the three months ended March 31, 2021, or this Report, contains forward-looking statements within the meaning of the federal securities
laws, which statements are subject to substantial risks and uncertainties. These forward-looking statements are intended to qualify for
the safe harbor from liability established by the Private Securities Litigation Reform Act of 1995. All statements other than statements
of historical fact included in this Report, or incorporated by reference into this Report, are forward-looking statements. Throughout
this Report, we have attempted to identify forward-looking statements by using words such as &ldquo;may,&rdquo; &ldquo;believe,&rdquo;
&ldquo;will,&rdquo; &ldquo;could,&rdquo; &ldquo;project,&rdquo; &ldquo;anticipate,&rdquo; &ldquo;expect,&rdquo; &ldquo;estimate,&rdquo;
&ldquo;should,&rdquo; &ldquo;continue,&rdquo; &ldquo;potential,&rdquo; &ldquo;plan,&rdquo; &ldquo;forecasts,&rdquo; &ldquo;goal,&rdquo;
&ldquo;seek,&rdquo; &ldquo;intend,&rdquo; &ldquo;predict,&rdquo; other forms of these words or similar words or expressions or the negative
thereof, although not all forward-looking statements contain these terms. Such statements address future events and conditions concerning,
among other things, intellectual property, or IP, acquisition and development, licensing and enforcement activities, other related business
activities, the impact of the COVID-19 pandemic, capital expenditures, earnings, litigation, regulatory matters, markets for our services,
liquidity and capital resources and accounting matters. Actual results in each case could differ materially from those anticipated in
such statements by reason of factors such as our ability to invest in new technologies and patents, future global economic conditions,
changes in demand for our services, legislative, regulatory and competitive developments in markets in which we and our subsidiaries
operate, results of litigation and other circumstances affecting anticipated revenues and costs.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><FONT STYLE="color: Black">We have based our forward-looking statements
on management&rsquo;s current expectations and projections about trends affecting our business and industry and other future events.
Although we do not make forward-looking statements unless we believe we have a reasonable basis for doing so, we cannot guarantee their
accuracy. Forward-looking statements are subject to substantial risks and uncertainties that could cause our future business, financial
condition, results of operations or performance to differ materially from our historical results or those expressed or implied in any
forward-looking statement contained in this Report. Some of the risks and uncertainties that may cause actual results to differ from
those expressed or implied in the forward-looking statements are described in &ldquo;Risk Factors&rdquo; included in Part II, Item1A
of this Report, and in &ldquo;Risk Factors&rdquo; included in Part I, Item 1A of our Annual Report on Form 10-K for the fiscal year ended
December 31, 2020, filed with the Securities and Exchange Commission, or the SEC, on March 29, 2021, or our Annual Report, as well as
in our other public filings with the SEC. In addition, actual results may differ as a result of additional risks and uncertainties of
which we are currently unaware or which we do not currently view as material to our business.</FONT></P>

transfer of control of promised bundled IP Rights and other contractual performance obligations to licensees in an amount that reflects
the consideration we expect to receive in exchange for those IP Rights. Revenue contracts that provide promises to grant the right to
use IP Rights as they exist at the point in time at which the IP Rights are granted, are accounted for as performance obligations satisfied
at a point in time and revenue is recognized at the point in time that the applicable performance obligations are satisfied and all other

revenue contracts executed by the Company primarily provided for the payment of contractually determined, one-time, paid-up license fees

fees from sales-based revenue contracts, the majority of which were originally executed in prior periods, which provide for the payment
of quarterly license fees based on quarterly sales of applicable product units by licensees (&ldquo;Recurring Revenue Agreements&rdquo;).
Revenues may also include court ordered settlements or awards related to our patent portfolio or sales of our patent portfolio. IP Rights
granted included the following, as applicable: (i) the grant of a non-exclusive, retroactive and future license to manufacture and/or
sell products covered by patented technologies, (ii) a covenant-not-to-sue, (iii) the release of the licensee from certain claims, and
(iv) the dismissal of any pending litigation. The IP Rights granted were perpetual in nature, extending until the legal expiration date
of the related patents. The individual IP Rights are not accounted for as separate performance obligations, as (i) the nature of the
promise, within the context of the contract, is to transfer combined items to which the promised IP Rights are inputs and (ii) the Company's
promise to transfer each individual IP right described above to the customer is not separately identifiable from other promises to transfer
IP Rights in the contract.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"><FONT STYLE="color: Black">Since the promised IP Rights
are not individually distinct, the Company combined each individual IP Right in the contract into a bundle of IP Rights that is distinct,
and accounted for all of the IP Rights promised in the contract as a single performance obligation. The IP Rights granted were &ldquo;functional
IP rights&rdquo; that have significant standalone functionality. Acacia's subsequent activities do not substantively change that functionality
and do not significantly affect the utility of the IP to which the licensee has rights. Acacia&rsquo;s operating subsidiaries have no
further obligation with respect to the grant of IP Rights, including no express or implied obligation to maintain or upgrade the technology,
or provide future support or services. The contracts provide for the grant (i.e., transfer of control) of the licenses, covenants-not-to-sue,
releases, and other significant deliverables upon execution of the contract. Licensees legally obtain control of the IP Rights upon execution
of the contract. As such, the earnings process is complete and revenue is recognized upon the execution of the contract, when collectability
is probable and all other revenue recognition criteria have been met. Revenue contracts generally provide for payment of contractual
amounts with 30-90 days of execution of the contract, or the end of the quarter in which the sale or usage occurs for Recurring Revenue
Agreements. Contractual payments made by licensees are generally non-refundable.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"><FONT STYLE="color: Black">For sales-based royalties,
the Company includes in the transaction price some or all of an amount of estimated variable consideration to the extent that it is probable
that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable
consideration is subsequently resolved. Notwithstanding, revenue is recognized for a sales-based royalty promised in exchange for a license
of IP Rights when the later of (i) the subsequent sale or usage occurs, or (ii) the performance obligation to which some or all of the
sales-based royalty has been allocated has been satisfied. Estimates are generally based on historical levels of activity, if available.</FONT></P>

with significant financing components (either explicit or implicit) are recognized at an amount that reflects the price that a licensee
would have paid if the licensee had paid cash for the IP Rights when they transfer to the licensee. In determining the transaction price,
the Company adjusts the promised amount of consideration for the effects of the time value of money. As a practical expedient, the Company
does not adjust the promised amount of consideration for the effects of a significant financing component if the Company expects, at
contract inception, that the period between when the entity transfers promised IP Rights to a customer and when the customer pays for
the IP Rights will be one year or less.</FONT></P>

at a point in time or over time, allocating the transaction price to separate performance obligations, determining whether contracts

assets for potential impairment annually (quarterly for patents) and when events or changes in circumstances indicate the carrying amount
of an asset may not be recoverable. In the event the expected undiscounted future cash flows resulting from the use of the asset is less
than the carrying amount of the asset, an impairment loss is recorded in an amount equal to the excess of the asset&rsquo;s carrying
value over its fair value. If an asset is determined to be impaired, the loss is measured based on quoted market prices in active markets,
if available. If quoted market prices are not available, the estimate of fair value is based on various valuation techniques, including
a discounted value of estimated future cash flows. In the event that management decides to no longer allocate resources to a patent portfolio,
an impairment loss equal to the remaining carrying value of the asset is recorded. Refer to Note 4 for additional information.</FONT></P>

the &ldquo;Income Approach,&rdquo; focusing on the estimated future net income-producing capability of the patent portfolios over their
estimated remaining economic useful life. Estimates of future after-tax cash flows are converted to present value through &ldquo;discounting,&rdquo;
including an estimated rate of return that accounts for both the time value of money and investment risk factors. Estimated cash inflows
are typically based on estimates of reasonable royalty rates for the applicable technology, applied to estimated market data. Estimated
cash outflows are based on existing contractual obligations, such as contingent legal fee and inventor royalty obligations, applied to
estimated license fee revenues, in addition to other estimates of out-of-pocket expenses associated with a specific patent portfolio&rsquo;s
licensing and enforcement program. The analysis also contemplates consideration of current information about the patent portfolio including,
status and stage of litigation, periodic results of the litigation process, strength of the patent portfolio, technology coverage and
other pertinent information that could impact future net cash flows.</FONT></P>

technique. Compensation cost is recognized with a market-based vesting condition provided that the requisite service is rendered, regardless
of when, if ever, the market condition is satisfied. Assumptions utilized in connection with the Monte Carlo valuation technique included:
estimated risk-free interest rate of 1.38 percent; term of 3.00 years; expected volatility of 38 percent; and expected dividend yield
of 0 percent. The risk-free interest rate was determined based on the yields available on U.S. Treasury zero-coupon issues. The expected
stock price volatility was determined using historical volatility. The expected dividend yield was based on expectations regarding dividend
payments.</FONT></P>

to be bifurcated from their host contract are valued separately from the host instrument. The binomial model determines the value of
a convertible bond instrument by valuing its two separate components (i.e., a cash only component which is subject to the selected risk-adjusted
discount rate and an equity component where settlement is subject to a risk-free rate) within a single lattice framework. The binomial
model utilizes the Tsiveriotis and Fernandes implementation in which a convertible instrument is split into two separate components:
a cash-only component which is subject to the selected risk-adjusted discount rate and an equity component which is subject only to the
risk-free rate. The model considers the (i) implied volatility of the value of our common stock, (ii) appropriate risk-free interest
rate, (iii) credit spread, (iv) dividend yield, (v) dividend accrual (and a step-up in rates), and (vi) event probabilities of the various
conversion and redemption scenarios.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">The volatility of the Company&rsquo;s common stock is estimated by
analyzing the Company&rsquo;s historical volatility, implied volatility of publicly traded stock options, and the Company&rsquo;s current
asset composition and financial leverage. The selected volatility, as described below, represents a haircut from the Company&rsquo;s
actual realized historical volatility. A volatility haircut is a concept used to describe a commonly observed occurrence in which the
volatility implied by market prices involving options, warrants, and convertible debt is lower than historical actual realized volatility.
The assumed base case term used in the valuation model is the period remaining until November 15, 2027, the maturity date. The risk-free
interest rate is based on the yield on the U.S. Treasury with a remaining term equal to the expected term of the conversion and early
redemption options. The significant assumptions utilized in the Company&rsquo;s valuation of the embedded derivative at March 31, 2021
are as follows: volatility of 30 percent, risk-free rate of 1.3 percent, discount rate of 8.8 percent, and a dividend yield of 0 percent.
The fair value measurement of the embedded derivative is sensitive to these assumptions and changes in these assumptions could result
in a materially different fair value measurement. Refer to Note 10 for additional information.</P>

Acacia Entities, Monarch Networking Solutions LLC (&ldquo;Monarch&rdquo;), Acacia board member Katharine Wolanyk, and Transpacific IP
Group, Ltd., or Transpacific. Slingshot alleges that the Acacia Entities and Monarch misappropriated its confidential and proprietary
information, purportedly furnished to the Acacia Entities and Monarch by Ms. Wolanyk, in acquiring a patent portfolio from Transpacific
after Slingshot&rsquo;s exclusive option to purchase the same patent portfolio from Transpacific had already expired. Slingshot seeks
monetary damages, as well as equitable and injunctive relief related to its alleged right to own the portfolio. On March 15, 2021, the
court issued orders granting Monarch&rsquo;s motion to dismiss for lack of personal jurisdiction and Ms. Wolanyk&rsquo;s motion to dismiss
for lack of subject matter jurisdiction. The Acacia Entities maintain that Slingshot&rsquo;s allegations are baseless, that the Acacia
Entities neither had access to nor used Slingshot&rsquo;s information in acquiring the portfolio, that the Acacia Entities acquired the
portfolio as a result of the independent efforts of its IP licensing group, and that Slingshot suffered no damages given its exclusive
option to purchase the portfolio had already ended and it has proven itself incapable of closing on the portfolio purchase.<FONT STYLE="font-family: Times New Roman, Times, Serif"></FONT></FONT></P>

stock from acquiring additional shares of the Company&rsquo;s common stock (subject to certain exceptions). There is no guarantee, however,

each right would initially entitle the holder to purchase one one-thousandth of a share of the Company&rsquo;s Series B Junior Participating

the Company is required to use observable market inputs (Level 1 - quoted market prices) when measuring fair value. In such cases, the
level at which the fair value measurement falls is determined based on the lowest level input that is significant to the fair value measurement.
The assessment of the significance of a particular input requires judgment and considers factors specific to the asset or liability being
measured. In certain cases, inputs used to measure fair value fall into different levels of the fair value hierarchy.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><FONT STYLE="color: Black">As of the date of this report, our operating
subsidiaries have two pending patent infringement case with a scheduled trial date in the next twelve months. Patent infringement trials
are components of our overall patent licensing process and are one of many factors that contribute to possible future revenue generating
opportunities for us. Scheduled trial dates, as promulgated by the respective court, merely provide an indication of when, in future
periods, the trials may occur according to the court&rsquo;s scheduling calendar at a specific point in time. A court may change previously
scheduled trial dates. In fact, courts often reschedule trial dates for various reasons that are unrelated to the underlying patent assets
and typically for reasons that are beyond our control. While scheduled trial dates provide an indication of the timing of possible future
revenue generating opportunities for us, the trials themselves and the immediately preceding periods represent the possible future revenue
generating opportunities. These future opportunities can result in varying outcomes. In fact, it is difficult to predict the outcome
of patent enforcement litigation at the trial level and outcomes can be unfavorable. It can be difficult to understand complex patented
technologies, and as a result, this may lead to a higher rate of unfavorable litigation outcomes. Moreover, in the event of a favorable
outcome, there is, in our experience, a higher rate of successful appeals in patent enforcement litigation than more standard business
litigation. Such appeals are expensive and time consuming, resulting in increased costs and a potential for delayed or foregone revenue
opportunities in the event of modification or reversal of favorable outcomes. Although we diligently pursue enforcement litigation, we
cannot predict with reliability the decisions made by juries and trial courts. Please refer to Item 1A. &ldquo;Risk Factors&rdquo; for
additional information regarding trials, patent litigation and related risks.</FONT></P>

Purchase Agreement with Starboard and the Buyers, on June 4, 2020, the Company issued $115 million in Notes to the Buyers. Also on June
4, 2020, in connection with the issuance of the Notes, the Company entered into a Supplemental Agreement with Starboard, or the Supplemental
Agreement, through which, the Company agreed to redeem $80 million aggregate principal amount of the Notes by September 30, 2020, and
$35 million aggregate principal amount of the Notes by December 31, 2020, resulting in the total principal outstanding being paid by
December 31, 2020. Per the Supplemental Agreement, interest is payable semiannually at a rate of 6.00% per annum, and in an event of
default, the interest rate is increased to 10% per annum. The Notes outlined certain financial and non-financial covenants. Additionally,
all or any portion of the principal amount outstanding under the Notes may, at the election of the holders, be surrendered to the Company

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><FONT STYLE="color: Black">On June 30, 2020, the Company entered into
an Exchange Agreement, or the Exchange Agreement, with Merton Acquisition HoldCo LLC, a Delaware limited liability company and wholly-owned
subsidiary of the Company, or Merton, and Starboard, on behalf of itself and on behalf of the Buyers, including the holders of the Notes.
Pursuant to the Exchange Agreement, the holders of the Notes exchanged the entire outstanding principal amount of the Notes for new senior
notes, or the New Notes, issued by Merton and having an aggregate outstanding original principal amount of $115 million. The New Notes
bear interest at a rate of 6.00% per annum and will mature December 31, 2020. The New Notes are fully guaranteed by the Company and are
secured by an all-assets pledge of the Company and Merton and non-recourse equity pledges of each of the Company&rsquo;s material subsidiaries.
Pursuant to the Exchange Agreement, the New Notes (i) are deemed to be &ldquo;Notes&rdquo; for purposes of the Securities Purchase Agreement,
(ii) are deemed to be &ldquo;June 2020 Approved Investment Notes&rdquo; for purposes of the Supplemental Agreement, and therefore the
Company agreed to redeem $80 million principal amount of the New Notes by September 30, 2020 and $35 million principal amount of the
New Notes by December 31, 2020, and (iii) are deemed to be &ldquo;Notes&rdquo; for the purposes of the Series B Warrants, and therefore
may be tendered pursuant to a Note Cancellation under the Series B Warrants on the terms set forth in the Series B Warrants and the New
Notes. Delivery of notes in the form of the New Notes will satisfy the delivery of Exchange Notes pursuant to Section 16(i) of the Certificate
of Designations of the Company&rsquo;s Series A Convertible Preferred Stock, par value $0.001 per share. The New Notes will not be deemed
to be &ldquo;Notes&rdquo; for the purposes of the Registration Rights Agreement, dated as of November 18, 2019, by and between the Company,
Starboard and the Buyers. The deadline to redeem the entire principal amount of the New Notes was subsequently extended by the parties
to July 15, 2021. Refer to Note 10 to the consolidated financial statements elsewhere herein for additional information.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">The provision for income taxes is determined using an effective tax
rate. For the three months ended March 31, 2021, the Company&rsquo;s estimated annual effective tax rate of (0.04%) was lower than the
U.S. federal statutory rate primarily due to the change in valuation allowance, as well as state income taxes. The effective tax rate
may be subject to fluctuations during the year as new information is obtained which may affect the assumptions used to estimate the effective
tax rate, including factors such as expected utilization of net operating loss carryforwards, changes in or the interpretation of tax
laws in jurisdictions where the Company conducts business, the Company&rsquo;s expansion into new states or foreign countries, and the
amount of valuation allowances against deferred tax assets. For the three months ended March 31, 2021, the Company recorded a provision
for income taxes of $9,700, which was primarily comprised of state income taxes. For the three month period ended March 31, 2020, the
Company recorded a benefit for income taxes of which primarily reflects the impact of state taxes and foreign taxes withholding or refund
incurred on revenue agreements executed with third-party licensees domiciled in foreign jurisdictions.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">The Company recognizes deferred tax assets and liabilities for temporary
differences between the financial reporting basis and the tax basis of its assets and liabilities along with net operating loss and tax
credit carryforwards. The Company records a valuation allowance against its deferred tax assets to reduce the net carrying value to an
amount it believes is more likely than not to be realized. When the Company establishes or reduces the valuation allowance against its
deferred tax assets, the provision for income taxes will increase or decrease, respectively, in the period such determination is made.
For the three months ended March 31, 2021, the Company has recorded a full valuation allowance against its deferred tax assets as they
are not expected to be realized.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">On March 27, 2020, the United States enacted the CARES Act which provides
certain income tax benefits including the ability to carryback federal NOLs generated in 2018 through 2020 for an extended five year period
and increased the limitation for the deduction of interest expense from 30 percent to 50 percent of modified taxable income. The CARES
Act also provides other economic benefits such as allowing employers to defer payment of the employer&rsquo;s portion of payroll taxes
for 2020 and a refundable employee retention credit of up to $5,000 per eligible employee wages. The Company did not realize benefits
from the provisions of the CARES Act including the extended NOL carryback period, the payroll tax deferral, and the employee retention
credit.</P>

approved a stock repurchase program, which authorized the purchase of up to $10.0 million of the Company's common stock through open
market purchases, through block trades, through 10b5-1 plans, or by means of private purchases, from time to time, through July 31, 2020.
In determining whether or not to repurchase any shares of Acacia&rsquo;s common stock, Acacia&rsquo;s Board of Directors consider such
factors as the impact of the repurchase on Acacia&rsquo;s cash position, as well as Acacia&rsquo;s capital needs and whether there is
a better alternative use of Acacia&rsquo;s capital. Acacia has no obligation to repurchase any amount of its common stock under the Stock
Repurchase Program.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><FONT STYLE="color: Black">The primary objective of our short-term
investment activities is to preserve principal while concurrently maximizing the income we receive from our equity securities at fair
value without significantly increasing risk. Some of the securities that we invest in may be subject to interest rate risk and/or market
risk. This means that a change in prevailing interest rates, with respect to interest rate risk, or a change in the value of the United
States equity markets, with respect to market risk, may cause the principal amount or market value of the equity securities at fair value
to fluctuate. For example, if we hold a security that was issued with a fixed interest rate at the then-prevailing rate and the prevailing
interest rate later rises, the current value of the principal amount of our investment may decline. To minimize these risks in the future,
we intend to maintain our portfolio of cash equivalents and equity securities at fair value securities in a variety of securities, including
commercial paper, money market funds, high-grade corporate bonds, government and non-government debt securities and certificates of deposit.
In general, money market funds are not subject to market risk because the interest paid on such funds fluctuates with the prevailing
interest rate. Accordingly, a 100 basis point increase in interest rates or a 10% decline in the value of the United States equity markets
would not be expected to have a material impact on the value of such money market funds. Investments in U.S. government and corporate
fixed income securities are subject to interest rate risk and will decline in value if interest rates increase. However, due to the relatively
short duration of our debt securities portfolio, an immediate 100 basis point increase in interest rates would have no material
impact on our financial condition, results of operations or cash flows. Declines in interest rates over time will, however, reduce our
interest income.</FONT></P>

there are resource constraints, and the benefits of controls must be considered relative to their costs. Further, because of the inherent
limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud
will not occur or that all control issues and instances of fraud, if any, have been detected. The design of any system of controls is
based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed
in achieving its stated goals under all potential future conditions. Projections of any evaluation of the effectiveness of controls to
future periods are subject to risks. Over time, controls may become inadequate because of changes in conditions or deterioration in the
degree of compliance with policies or procedures.</FONT></P>

In such event, a court may issue monetary sanctions against us or our operating subsidiaries or award attorney&rsquo;s fees and/or expenses

the future determine to pursue could continue for years and continue to consume significant financial and management resources. The counterparties
to our litigation are sometimes large, well-financed companies with substantially greater resources than us. We cannot assure you that
any of our current or future litigation matters will result in a favorable outcome for us. In addition, in part due to the appeals process
and other legal processes, even if we obtain favorable interim rulings or verdicts in particular litigation matters, they may not be
predictive of the ultimate resolution of the dispute. Also, we cannot assure you that we will not be exposed to claims or sanctions against
us which may be costly or impossible for us to defend. Unfavorable or adverse outcomes may result in losses, exhaustion of financial
resources or other adverse effects which could encumber our ability to effectively and efficiently monetize our assets.</FONT></P>

LLC, or Slingshot, filed a lawsuit in Delaware Chancery Court against the Company and Acacia Research Group, LLC, or collectively, the
Acacia Entities, Monarch Networking Solutions LLC (&ldquo;Monarch&rdquo;), Acacia board member Katharine Wolanyk, and Transpacific IP
Group, Ltd., or Transpacific. Slingshot alleges that the Acacia Entities and Monarch misappropriated its confidential and proprietary
information, purportedly furnished to the Acacia Entities and Monarch by Ms. Wolanyk, in acquiring a patent portfolio from Transpacific
after Slingshot&rsquo;s exclusive option to purchase the same patent portfolio from Transpacific had already expired. Slingshot seeks
monetary damages, as well as equitable and injunctive relief related to its alleged right to own the portfolio. On March 15, 2021, the
court issued orders granting Monarch&rsquo;s motion to dismiss for lack of personal jurisdiction and Ms. Wolanyk&rsquo;s motion to dismiss
for lack of subject matter jurisdiction. The Acacia Entities maintain that Slingshot&rsquo;s allegations are baseless, that the Acacia
Entities neither had access to nor used Slingshot&rsquo;s information in acquiring the portfolio, that the Acacia Entities acquired the
portfolio as a result of the independent efforts of its IP licensing group, and that Slingshot suffered no damages given its exclusive
option to purchase the portfolio had already ended and it has proven itself incapable of closing on the portfolio purchase.</FONT></P>

Revenue contracts that provide promises to grant the right to&#13;use IP Rights as they exist at the point in time at which the IP Rights are granted, are accounted for as performance obligations satisfied&#13;at a point in time and revenue is recognized at the point in time that the applicable performance obligations are satisfied and all other&#13;revenue recognition criteria have been met.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in; color: #7030A0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; color: #7030A0"&gt;&lt;font style="color: Black"&gt;For&#13;the periods presented, revenue contracts executed by the Company primarily provided for the payment of contractually determined, one-time,&#13;paid-up license fees in consideration for the grant of certain IP Rights for patented technologies owned or controlled by Acacia. Revenues&#13;also included license fees from sales-based revenue contracts, the majority of which were originally executed in prior periods, which&#13;provide for the payment of quarterly license fees based on quarterly sales of applicable product units by licensees (&amp;#8220;Recurring&#13;Revenue Agreements&amp;#8221;). Revenues may also include court ordered settlements or awards related to our patent portfolio or sales of&#13;our patent portfolio. IP Rights granted included the following, as applicable: (i) the grant of a non-exclusive, retroactive and future&#13;license to manufacture and/or sell products covered by patented technologies, (ii) a covenant-not-to-sue, (iii) the release of the licensee&#13;from certain claims, and (iv) the dismissal of any pending litigation. The IP Rights granted were perpetual in nature, extending until&#13;the legal expiration date of the related patents. The individual IP Rights are not accounted for as separate performance obligations,&#13;as (i) the nature of the promise, within the context of the contract, is to transfer combined items to which the promised IP Rights are&#13;inputs and (ii) the Company's promise to transfer each individual IP right described above to the customer is not separately identifiable&#13;from other promises to transfer IP Rights in the contract.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; color: #7030A0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; color: #7030A0"&gt;&lt;font style="color: Black"&gt;Since the promised IP Rights&#13;are not individually distinct, the Company combined each individual IP Right in the contract into a bundle of IP Rights that is distinct,&#13;and accounted for all of the IP Rights promised in the contract as a single performance obligation. The IP Rights granted were &amp;#8220;functional&#13;IP rights&amp;#8221; that have significant standalone functionality. Acacia's subsequent activities do not substantively change that functionality&#13;and do not significantly affect the utility of the IP to which the licensee has rights. Acacia&amp;#8217;s operating subsidiaries have no&#13;further obligation with respect to the grant of IP Rights, including no express or implied obligation to maintain or upgrade the technology,&#13;or provide future support or services. The contracts provide for the grant (i.e., transfer of control) of the licenses, covenants-not-to-sue,&#13;releases, and other significant deliverables upon execution of the contract. Licensees legally obtain control of the IP Rights upon execution&#13;of the contract. As such, the earnings process is complete and revenue is recognized upon the execution of the contract, when collectability&#13;is probable and all other revenue recognition criteria have been met. Revenue contracts generally provide for payment of contractual&#13;amounts with 30-90 days of execution of the contract, or the end of the quarter in which the sale or usage occurs for Recurring Revenue&#13;Agreements. Contractual payments made by licensees are generally non-refundable.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; color: #7030A0"&gt;&lt;font style="color: Black"&gt;For sales-based royalties,&#13;the Company includes in the transaction price some or all of an amount of estimated variable consideration to the extent that it is probable&#13;that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable&#13;consideration is subsequently resolved. Notwithstanding, revenue is recognized for a sales-based royalty promised in exchange for a license&#13;of IP Rights when the later of (i) the subsequent sale or usage occurs, or (ii) the performance obligation to which some or all of the&#13;sales-based royalty has been allocated has been satisfied. Estimates are generally based on historical levels of activity, if available.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; color: #7030A0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; color: #7030A0"&gt;&lt;font style="color: Black"&gt;Revenues from contracts&#13;with significant financing components (either explicit or implicit) are recognized at an amount that reflects the price that a licensee&#13;would have paid if the licensee had paid cash for the IP Rights when they transfer to the licensee. In determining the transaction price,&#13;the Company adjusts the promised amount of consideration for the effects of the time value of money. As a practical expedient, the Company&#13;does not adjust the promised amount of consideration for the effects of a significant financing component if the Company expects, at&#13;contract inception, that the period between when the entity transfers promised IP Rights to a customer and when the customer pays for&#13;the IP Rights will be one year or less.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; color: #7030A0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; color: #7030A0"&gt;&lt;font style="color: Black"&gt;In general, the Company&#13;is required to make certain judgments and estimates in connection with the accounting for revenue contracts with customers. Such areas&#13;may include identifying performance obligations in the contract, estimating the timing of satisfaction of performance obligations, determining&#13;whether a promise to grant a license is distinct from other promised goods or services, evaluating whether a license transfers to a customer&#13;at a point in time or over time, allocating the transaction price to separate performance obligations, determining whether contracts&#13;contain a significant financing component, and estimating revenues recognized at a point in time for sales-based royalties.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif;

The binomial model determines the value of&#13;a convertible bond instrument by valuing its two separate components (i.e., a cash only component which is subject to the selected risk-adjusted&#13;discount rate and an equity component where settlement is subject to a risk-free rate) within a single lattice framework. The binomial&#13;model utilizes the Tsiveriotis and Fernandes implementation in which a convertible instrument is split into two separate components:&#13;a cash-only component which is subject to the selected risk-adjusted discount rate and an equity component which is subject only to the&#13;risk-free rate. The model considers the (i) implied volatility of the value of our common stock, (ii) appropriate risk-free interest&#13;rate, (iii) credit spread, (iv) dividend yield, (v) dividend accrual (and a step-up in rates), and (vi) event probabilities of the various&#13;conversion and redemption scenarios.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;&amp;#160;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;The volatility of the Company&amp;#8217;s common stock is estimated by&#13;analyzing the Company&amp;#8217;s historical volatility, implied volatility of publicly traded stock options, and the Company&amp;#8217;s current&#13;asset composition and financial leverage. The selected volatility, as described below, represents a haircut from the Company&amp;#8217;s&#13;actual realized historical volatility. A volatility haircut is a concept used to describe a commonly observed occurrence in which the&#13;volatility implied by market prices involving options, warrants, and convertible debt is lower than historical actual realized volatility.&#13;The assumed base case term used in the valuation model is the period remaining until November 15, 2027, the maturity date. The risk-free&#13;interest rate is based on the yield on the U.S. Treasury with a remaining term equal to the expected term of the conversion and early&#13;redemption options. The significant assumptions utilized in the Company&amp;#8217;s valuation of the embedded derivative at March 31, 2021&#13;are as follows: volatility of 30 percent, risk-free rate of 1.3 percent, discount rate of 8.8 percent, and a dividend yield of 0 percent.&#13;The fair value measurement of the embedded derivative is sensitive to these assumptions and changes in these assumptions could result&#13;in a materially different fair value measurement.

The fair value of restricted stock and restricted stock unit awards is determined by the product of the number of shares or units&#13;granted and the grant date market price of the underlying common stock. The fair value of each option award is estimated on the date&#13;of grant using a Black-Scholes option-pricing model. Forfeitures are accounted for as they occur.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;Restricted stock units granted in September&#13;2019 with market-based vesting conditions vest based upon the Company achieving specified stock price targets over a three-year period.&#13;The effect of a market condition is reflected in the estimate of the grant-date fair value of the options utilizing a Monte Carlo valuation&#13;technique. Compensation cost is recognized with a market-based vesting condition provided that the requisite service is rendered, regardless&#13;of when, if ever, the market condition is satisfied. Assumptions utilized in connection with the Monte Carlo valuation technique included:&#13;estimated risk-free interest rate of 1.38 percent; term of 3.00 years; expected volatility of 38 percent; and expected dividend yield&#13;of 0 percent. The risk-free interest rate was determined based on the yields available on U.S. Treasury zero-coupon issues. The expected&#13;stock price volatility was determined using historical volatility. The expected dividend yield was based on expectations regarding dividend&#13;payments.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="font-family: Times New Roman, Times, Serif; color: Black"&gt;Profits&#13;Interest Units (&amp;#8220;Units&amp;#8221;) were accounted for in accordance with Accounting Standards Codification (&amp;#8220;ASC&amp;#8221;) 718-10,&#13;&amp;#8220;Compensation - Stock Compensation.&amp;#8221; The vesting conditions did not meet the definition of service, market or performance&#13;conditions, as defined in ASC 718. As such, the Units were classified as liability awards. Compensation expense was adjusted for changes&#13;in fair value prorated for the portion of the requisite service period rendered. Initially, compensation expense was recognized on a&#13;straight-line basis over the employee&amp;#8217;s requisite service period (generally the vesting period of the equity award) which was five&#13;years. Upon full vesting of the award, which occurred during the three months ended September 30, 2017, previously unrecognized compensation&#13;expense was immediately recognized in the period. The Company has a purchase option to purchase the vested Units that are not otherwise&#13;forfeited after termination of continuous service. The exercise price of the purchase option is the fair market value of the Units on&#13;the date of termination of continuous service. As of March 31, 2021, the Units totaled $591,000, which was their fair value as of December&#13;31, 2018 after termination of service.&lt;/font&gt;&lt;/p&gt;</us-gaap:ShareBasedCompensationOptionAndIncentivePlansPolicy>

In the event the expected undiscounted future cash flows resulting from the use of the asset is less&#13;than the carrying amount of the asset, an impairment loss is recorded in an amount equal to the excess of the asset&amp;#8217;s carrying&#13;value over its fair value. If an asset is determined to be impaired, the loss is measured based on quoted market prices in active markets,&#13;if available. If quoted market prices are not available, the estimate of fair value is based on various valuation techniques, including&#13;a discounted value of estimated future cash flows. In the event that management decides to no longer allocate resources to a patent portfolio,&#13;an impairment loss equal to the remaining carrying value of the asset is recorded.

Estimates of future after-tax cash flows are converted to present value through &amp;#8220;discounting,&amp;#8221;&#13;including an estimated rate of return that accounts for both the time value of money and investment risk factors. Estimated cash inflows&#13;are typically based on estimates of reasonable royalty rates for the applicable technology, applied to estimated market data. Estimated&#13;cash outflows are based on existing contractual obligations, such as contingent legal fee and inventor royalty obligations, applied to&#13;estimated license fee revenues, in addition to other estimates of out-of-pocket expenses associated with a specific patent portfolio&amp;#8217;s&#13;licensing and enforcement program. The analysis also contemplates consideration of current information about the patent portfolio including,&#13;status and stage of litigation, periodic results of the litigation process, strength of the patent portfolio, technology coverage and&#13;other pertinent information that could impact future net cash flows.&lt;/font&gt;&lt;/p&gt;</us-gaap:ImpairmentOrDisposalOfLongLivedAssetsPolicyTextBlock>

The Company intends to leverage its (i) access to flexible capital that can be deployed unconditionally, (ii) expertise&#13;in corporate governance and operational restructuring, (iii) willingness to invest in out of favor industries and businesses that suffer&#13;from a complexity discount and untangle complex, multi-factor situations, and (iv) expertise and relationships in certain sectors, to&#13;complete strategic acquisitions of businesses, divisions, and/or assets with a focus on mature technology, healthcare, industrial and&#13;certain financial segments. Acacia seeks to identify opportunities where the Company believes it is an advantaged buyer, where the Company&#13;can avoid structured sale processes and create the opportunity to purchase businesses, divisions and/or assets of companies at an attractive&#13;price due to the Company&amp;#8217;s unique capabilities, relationships, or expertise, or where Acacia believes the target would be worth&#13;more to the Company than to other buyers.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;Acacia operates its business based on three&#13;key principles of People, Process and Performance and have built a management team with identified expertise in Research, Execution and&#13;Operation of the Company&amp;#8217;s targeted acquisitions.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;Acacia, through its operating subsidiaries,&#13;also currently engages in its legacy business of investing in, licensing and enforcing patented technologies. Acacia&amp;#8217;s operating&#13;subsidiaries partner with inventors and patent owners, applying their legal and technology expertise to patent assets to unlock the financial&#13;value in their patented inventions. In recent years, Acacia has also invested in technology companies. Acacia leverages its experience,&#13;expertise, data and relationships developed as a leader in the intellectual property (&amp;#8220;IP&amp;#8221;) industry to pursue these opportunities.&#13;In some cases, these opportunities will complement and/or supplement Acacia&amp;#8217;s primary licensing and enforcement business.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;Acacia&amp;#8217;s operating subsidiaries generate&#13;revenues and related cash flows from the granting of IP rights (hereinafter, &amp;#8220;IP Rights&amp;#8221;) for the use of patented technologies&#13;that its operating subsidiaries control or own. Acacia&amp;#8217;s operating subsidiaries assist patent owners with the prosecution and development&#13;of their patent portfolios, the protection of their patented inventions from unauthorized use, the generation of licensing revenue from&#13;users of their patented technologies and, where necessary, with the enforcement against unauthorized users of their patented technologies&#13;through the filing of patent infringement litigation.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;Acacia&amp;#8217;s operating subsidiaries are&#13;principals in the licensing and enforcement effort, obtaining control of the rights in the patent portfolio, or control of the patent&#13;portfolio outright. Acacia&amp;#8217;s operating subsidiaries own or control the rights to multiple patent portfolios, which include U.S.&#13;patents and certain foreign counterparts, covering technologies used in a wide variety of industries.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;Neither Acacia nor its operating subsidiaries&#13;invent new technologies or products; rather, Acacia depends upon the identification and investment in new patents, inventions and companies&#13;that own IP through its relationships with inventors, universities, research institutions, technology companies and others. If Acacia&amp;#8217;s&#13;operating subsidiaries are unable to maintain those relationships and identify and grow new relationships, then they may not be able&#13;to identify new technology-based opportunities for sustainable revenue and/or revenue growth.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;During the three months ended March 31,&#13;2021, Acacia obtained control of one new patent portfolio.

All intercompany transactions&#13;and balances have been eliminated in consolidation.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;font style="color: Black"&gt;&amp;#160;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;The accompanying unaudited condensed consolidated&#13;financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (&amp;#8220;U.S.&#13;GAAP&amp;#8221;) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly,&#13;certain information and footnotes required by U.S. GAAP in annual financial statements have been omitted or condensed in accordance with&#13;quarterly reporting requirements of the Securities and Exchange Commission (&amp;#8220;SEC&amp;#8221;). These interim unaudited condensed consolidated&#13;financial statements should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December&#13;31, 2020, as reported by Acacia in its Annual Report on Form 10-K filed with the SEC on March 29, 2021, as well as in our other public&#13;filings with the SEC. The condensed consolidated interim financial statements of Acacia include all adjustments of a normal recurring&#13;nature which, in the opinion of management, are necessary for a fair statement of Acacia&amp;#8217;s consolidated financial position as of&#13;March 31, 2021, and results of its operations and its cash flows for the interim periods presented. The consolidated results of operations&#13;for the three months ended March 31, 2021 are not necessarily indicative of the results to be expected for the entire fiscal year.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;&amp;#160;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;&lt;b&gt;Use of Estimates&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;The preparation of financial statements&#13;in conformity with generally accepted accounting principles in the United States of America requires management to make estimates and&#13;assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date&#13;of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results&#13;could differ from these estimates. Acacia believes that, of the significant accounting policies described herein, the accounting policies&#13;associated with revenue recognition, the valuation of the equity instruments, the valuation of Series A redeemable convertible preferred&#13;stock (the &amp;#8220;Series A Redeemable Convertible Preferred Stock&amp;#8221;), embedded derivatives, Series A warrants (the &amp;#8220;Series&#13;A Warrants&amp;#8221;), Series B warrants (the &amp;#8220;Series B Warrants&amp;#8221;), stock-based compensation expense, impairment of patent-related&#13;intangible assets, the determination of the economic useful life of amortizable intangible assets, income taxes and valuation allowances&#13;against net deferred tax assets, require its most difficult, subjective or complex judgments.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;&lt;b&gt;COVID-19 Pandemic and the CARES Act&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;The full impact of the COVID-19 pandemic&#13;continues to evolve as of the date of this report. While the Company does not expect the current situation to present direct risks to&#13;its business, and it has not had a material impact to date, the COVID-19 pandemic could adversely impact the Company&amp;#8217;s operations,&#13;as well as the operations of its licensees and other business partners. Our cash is held in major financial institutions in government&#13;instruments and high-quality short-term bonds. Our business is fully able to operate in a socially distanced and/or remote capacity and&#13;in accordance with applicable laws, policies, and best practices. Our workforce is provided ample paid sick leave, and we have in place&#13;robust disaster recovery and business continuity policies that have been revised to account for a long-term remote work contingency such&#13;as this. However, the ongoing pandemic may present risks that we do not currently consider material or risks that may evolve quickly&#13;that could have a materially adverse effect on our business, results of operations and financial condition.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;In response to the COVID-19 pandemic, the&#13;Coronavirus Aid, Relief and Economic Security Act (&amp;#34;CARES Act&amp;#34;) was signed into law on March 27, 2020. The CARES Act, among&#13;other things, includes tax provisions relating to refundable payroll tax credits, deferment of employer's social security payments, net&#13;operating loss utilization and carryback periods and modifications to the net interest deduction limitations. The CARES Act has not had&#13;a material impact on the Company&amp;#8217;s income tax provision.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;On December 27, 2020, the President of&#13;the United States signed the Consolidated Appropriations Act, 2021 (&amp;#8220;Consolidated Appropriations Act&amp;#8221;) into law. The Consolidated&#13;Appropriations Act is intended to enhance and expand certain provisions of the CARES Act, allows for the deductions of expenses related&#13;to the Payroll Protection Program funds received by companies, and provides an update to meals and entertainment expensing for 2021.&#13;The Consolidated Appropriations Act did not have a material impact to the Company&amp;#8217;s income tax provision for 2020. The Company&#13;will continue to evaluate the impact of the Consolidated Appropriations Act on its financial position, results of operations and cash&#13;flows, if any.&lt;/font&gt;&lt;/p&gt;</us-gaap:BusinessDescriptionAndBasisOfPresentationTextBlock>

In such event, a court may issue monetary sanctions against Acacia&#13;or its operating subsidiaries or award attorney&amp;#8217;s fees and/or expenses to a defendant(s), which could be material.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;&lt;i&gt;Facility Leases&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;font style="color: Black"&gt;&lt;i&gt;&amp;#160;&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;The Company primarily leases office facilities&#13;under operating lease arrangements that will end in various years through July 2024.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;On June 7, 2019, we entered into a building&#13;lease agreement (the &amp;#8220;New Lease&amp;#8221;) with Jamboree Center 4 LLC (the &amp;#8220;Landlord&amp;#8221;).

Slingshot alleges that the Acacia Entities and Monarch misappropriated its confidential and proprietary&#13;information, purportedly furnished to the Acacia Entities and Monarch by Ms. Wolanyk, in acquiring a patent portfolio from Transpacific&#13;after Slingshot&amp;#8217;s exclusive option to purchase the same patent portfolio from Transpacific had already expired. Slingshot seeks&#13;monetary damages, as well as equitable and injunctive relief related to its alleged right to own the portfolio. On March 15, 2021, the&#13;court issued orders granting Monarch&amp;#8217;s motion to dismiss for lack of personal jurisdiction and Ms. Wolanyk&amp;#8217;s motion to dismiss&#13;for lack of subject matter jurisdiction. The Acacia Entities maintain that Slingshot&amp;#8217;s allegations are baseless, that the Acacia&#13;Entities neither had access to nor used Slingshot&amp;#8217;s information in acquiring the portfolio, that the Acacia Entities acquired the&#13;portfolio as a result of the independent efforts of its IP licensing group, and that Slingshot suffered no damages given its exclusive&#13;option to purchase the portfolio had already ended and it has proven itself incapable of closing on the portfolio purchase.&lt;font style="font-family: Times New Roman, Times, Serif"&gt;&lt;/font&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;During the three months ended March 31,&#13;2021, we incurred no operating expenses for settlement and contingency accruals.

Acacia&#13;has no obligation to repurchase any amount of its common stock under the Stock Repurchase Program.

Our&#13;stockholders ratified the adoption of the Plan in July 2019. The purpose of the Plan is to protect the Company&amp;#8217;s ability to utilize&#13;potential tax assets, such as net operating loss carryforwards and tax credits to offset potential future taxable income.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;The Plan is designed to reduce the likelihood&#13;that the Company will experience an ownership change by discouraging (i) any person or group from acquiring beneficial ownership of 4.9%&#13;or more of the Company&amp;#8217;s outstanding common stock and (ii) any existing stockholders who, as of the time of the first public announcement&#13;of the adoption of the Plan, beneficially own more than 4.9% of the Company&amp;#8217;s then-outstanding shares of the Company&amp;#8217;s common&#13;stock from acquiring additional shares of the Company&amp;#8217;s common stock (subject to certain exceptions). There is no guarantee, however,&#13;that the Plan will prevent the Company from experiencing an ownership change.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;In connection with the adoption of the&#13;Plan, Acacia&amp;#8217;s Board of Directors authorized and declared a dividend distribution of one right for each outstanding share of the&#13;Company&amp;#8217;s common stock to stockholders of record at the close of business on March 16, 2019. On or after the distribution date,&#13;each right would initially entitle the holder to purchase one one-thousandth of a share of the Company&amp;#8217;s Series B Junior Participating&#13;Preferred Stock, $0.001 par value for a purchase price of $12.00. On March 15, 2021 the rights expired pursuant to their terms.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;&lt;b&gt;&amp;#160;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;The Company has a provision in its Amended&#13;and Restated Certificate of Incorporation, as amended (the &amp;#8220;Charter Provision&amp;#8221;) which generally prohibits transfers of its&#13;common stock that could result in an ownership change. Like the Plan, the purpose of the Charter Provision is to protect the Company&amp;#8217;s&#13;ability to utilize potential tax assets, such as net operating loss carryforwards and tax credits to offset potential future taxable&#13;income. The Charter Provision was approved by the Company&amp;#8217;s stockholders on July 15, 2019.&lt;/font&gt;&lt;/p&gt;</us-gaap:StockholdersEquityNoteDisclosureTextBlock>

MalinJ1 is included in the Company&amp;#8217;s consolidated financial statements because the Company, through its&#13;interest in the equity securities of MalinJ1, has the ability to control the operations and activities of MalinJ1. Viamet HoldCo LLC,&#13;a Delaware limited liability company and wholly-owned subsidiary of Acacia (see Note 11), is the majority shareholder of MalinJ1.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;A wholly owned subsidiary of Acacia is&#13;the general partner of the Acacia Intellectual Property Fund, L.P. (the &amp;#8220;Acacia IP Fund&amp;#8221;), which was formed in August 2010.&#13;The Acacia IP Fund has been included in the Company&amp;#8217;s consolidated financial statements since 2010, as Acacia&amp;#8217;s wholly owned&#13;subsidiary, the general partner of Acacia IP Fund, has the ability to control the operations and activities of the Acacia IP Fund. The&#13;Acacia IP Fund was terminated as of December 31, 2017 and dissolved in 2020.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&lt;b&gt;&amp;#160;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&lt;b&gt;Revenue Recognition&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&lt;i&gt;&amp;#160;&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"&gt;&lt;font style="color: Black"&gt;Revenue is recognized upon&#13;transfer of control of promised bundled IP Rights and other contractual performance obligations to licensees in an amount that reflects&#13;the consideration we expect to receive in exchange for those IP Rights. Revenue contracts that provide promises to grant the right to&#13;use IP Rights as they exist at the point in time at which the IP Rights are granted, are accounted for as performance obligations satisfied&#13;at a point in time and revenue is recognized at the point in time that the applicable performance obligations are satisfied and all other&#13;revenue recognition criteria have been met.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in; color: #7030A0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"&gt;&lt;font style="color: Black"&gt;For the periods presented,&#13;revenue contracts executed by the Company primarily provided for the payment of contractually determined, one-time, paid-up license fees&#13;in consideration for the grant of certain IP Rights for patented technologies owned or controlled by Acacia. Revenues also included license&#13;fees from sales-based revenue contracts, the majority of which were originally executed in prior periods, which provide for the payment&#13;of quarterly license fees based on quarterly sales of applicable product units by licensees (&amp;#8220;Recurring Revenue Agreements&amp;#8221;).&#13;Revenues may also include court ordered settlements or awards related to our patent portfolio or sales of our patent portfolio. IP Rights&#13;granted included the following, as applicable: (i) the grant of a non-exclusive, retroactive and future license to manufacture and/or&#13;sell products covered by patented technologies, (ii) a covenant-not-to-sue, (iii) the release of the licensee from certain claims, and&#13;(iv) the dismissal of any pending litigation. The IP Rights granted were perpetual in nature, extending until the legal expiration date&#13;of the related patents. The individual IP Rights are not accounted for as separate performance obligations, as (i) the nature of the&#13;promise, within the context of the contract, is to transfer combined items to which the promised IP Rights are inputs and (ii) the Company's&#13;promise to transfer each individual IP right described above to the customer is not separately identifiable from other promises to transfer&#13;IP Rights in the contract.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in; color: #7030A0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"&gt;&lt;font style="color: Black"&gt;Since the promised IP Rights&#13;are not individually distinct, the Company combined each individual IP Right in the contract into a bundle of IP Rights that is distinct,&#13;and accounted for all of the IP Rights promised in the contract as a single performance obligation. The IP Rights granted were &amp;#8220;functional&#13;IP rights&amp;#8221; that have significant standalone functionality. Acacia's subsequent activities do not substantively change that functionality&#13;and do not significantly affect the utility of the IP to which the licensee has rights. Acacia&amp;#8217;s operating subsidiaries have no&#13;further obligation with respect to the grant of IP Rights, including no express or implied obligation to maintain or upgrade the technology,&#13;or provide future support or services. The contracts provide for the grant (i.e., transfer of control) of the licenses, covenants-not-to-sue,&#13;releases, and other significant deliverables upon execution of the contract. Licensees legally obtain control of the IP Rights upon execution&#13;of the contract. As such, the earnings process is complete and revenue is recognized upon the execution of the contract, when collectability&#13;is probable and all other revenue recognition criteria have been met. Revenue contracts generally provide for payment of contractual&#13;amounts with 30-90 days of execution of the contract, or the end of the quarter in which the sale or usage occurs for Recurring Revenue&#13;Agreements. Contractual payments made by licensees are generally non-refundable.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"&gt;&lt;font style="color: Black"&gt;For sales-based royalties,&#13;the Company includes in the transaction price some or all of an amount of estimated variable consideration to the extent that it is probable&#13;that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable&#13;consideration is subsequently resolved. Notwithstanding, revenue is recognized for a sales-based royalty promised in exchange for a license&#13;of IP Rights when the later of (i) the subsequent sale or usage occurs, or (ii) the performance obligation to which some or all of the&#13;sales-based royalty has been allocated has been satisfied. Estimates are generally based on historical levels of activity, if available.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"&gt;&lt;font style="color: Black"&gt;Revenues from contracts&#13;with significant financing components (either explicit or implicit) are recognized at an amount that reflects the price that a licensee&#13;would have paid if the licensee had paid cash for the IP Rights when they transfer to the licensee. In determining the transaction price,&#13;the Company adjusts the promised amount of consideration for the effects of the time value of money. As a practical expedient, the Company&#13;does not adjust the promised amount of consideration for the effects of a significant financing component if the Company expects, at&#13;contract inception, that the period between when the entity transfers promised IP Rights to a customer and when the customer pays for&#13;the IP Rights will be one year or less.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"&gt;&lt;font style="color: Black"&gt;In general, the Company&#13;is required to make certain judgments and estimates in connection with the accounting for revenue contracts with customers. Such areas&#13;may include identifying performance obligations in the contract, estimating the timing of satisfaction of performance obligations, determining&#13;whether a promise to grant a license is distinct from other promised goods or services, evaluating whether a license transfers to a customer&#13;at a point in time or over time, allocating the transaction price to separate performance obligations, determining whether contracts&#13;contain a significant financing component, and estimating revenues recognized at a point in time for sales-based royalties.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;Revenues were comprised of the following&#13;for the periods presented:&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif;

In instances where there are no recoveries from potential&#13;infringers, no contingent legal fees are paid; however, Acacia&amp;#8217;s operating subsidiaries may be liable for certain out of pocket&#13;legal costs incurred pursuant to the underlying legal services agreement.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;Inventor royalty and contingent legal agreements typically provide&#13;for payment by the Company of contractual amounts 30 days subsequent to the fiscal quarter end during which related license fee payments&#13;are received from licensees by the Company.&lt;/p&gt;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&lt;i&gt;&amp;#160;&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&lt;i&gt;Concentrations&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;Financial instruments that potentially&#13;subject Acacia to concentrations of credit risk are cash equivalents, equity securities and accounts receivable. Acacia places its cash&#13;equivalents and equity securities primarily in highly rated money market funds and investment grade marketable securities. Cash and cash&#13;equivalents are also invested in deposits with certain financial institutions and may, at times, exceed federally insured limits.

Refer to Note 4 for additional&#13;information regarding our patents.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&lt;b&gt;&amp;#160;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&lt;b&gt;Impairment of Long-lived Assets&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&lt;i&gt;&amp;#160;&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;Acacia reviews long-lived assets and intangible&#13;assets for potential impairment annually (quarterly for patents) and when events or changes in circumstances indicate the carrying amount&#13;of an asset may not be recoverable. In the event the expected undiscounted future cash flows resulting from the use of the asset is less&#13;than the carrying amount of the asset, an impairment loss is recorded in an amount equal to the excess of the asset&amp;#8217;s carrying&#13;value over its fair value. If an asset is determined to be impaired, the loss is measured based on quoted market prices in active markets,&#13;if available. If quoted market prices are not available, the estimate of fair value is based on various valuation techniques, including&#13;a discounted value of estimated future cash flows. In the event that management decides to no longer allocate resources to a patent portfolio,&#13;an impairment loss equal to the remaining carrying value of the asset is recorded. Refer to Note 4 for additional information.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;Fair value is generally estimated using&#13;the &amp;#8220;Income Approach,&amp;#8221; focusing on the estimated future net income-producing capability of the patent portfolios over their&#13;estimated remaining economic useful life. Estimates of future after-tax cash flows are converted to present value through &amp;#8220;discounting,&amp;#8221;&#13;including an estimated rate of return that accounts for both the time value of money and investment risk factors. Estimated cash inflows&#13;are typically based on estimates of reasonable royalty rates for the applicable technology, applied to estimated market data. Estimated&#13;cash outflows are based on existing contractual obligations, such as contingent legal fee and inventor royalty obligations, applied to&#13;estimated license fee revenues, in addition to other estimates of out-of-pocket expenses associated with a specific patent portfolio&amp;#8217;s&#13;licensing and enforcement program. The analysis also contemplates consideration of current information about the patent portfolio including,&#13;status and stage of litigation, periodic results of the litigation process, strength of the patent portfolio, technology coverage and&#13;other pertinent information that could impact future net cash flows.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&lt;b&gt;&amp;#160;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&lt;b&gt;Cash and Cash Equivalents&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;Acacia considers all highly liquid, equity&#13;securities with original maturities of three months or less when purchased to be cash equivalents. For the periods presented, Acacia&amp;#8217;s&#13;cash equivalents are comprised of investments in AAA rated money market funds that invest in first-tier only securities, which primarily&#13;includes: domestic commercial paper, securities issued or guaranteed by the U.S. government or its agencies, U.S. bank obligations, and&#13;fully collateralized repurchase agreements. Acacia&amp;#8217;s cash equivalents are measured at fair value using quoted prices that represent&#13;Level 1 inputs.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&lt;b&gt;Long Term Restricted Cash &lt;/b&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;Long-term restricted cash relates&#13;primarily to the proceeds received from the issuance of Series A Redeemable Convertible Preferred Stock which are held in an escrow&#13;account.

They are reported at cost minus impairment, if any, plus or minus&#13;changes resulting from observable price changes in orderly transactions for an identical or similar investment of the same issuer. The&#13;fair values of the private company securities were estimated based on recent financing transactions and secondary market transactions&#13;and factoring in any adjustments for illiquidity or preference of these securities. Changes in fair value are reported in the consolidated&#13;statements of operations in other income (expense).&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&lt;b&gt;Investments at Fair Value&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;On an individual investment basis, Acacia&#13;may elect to account for investments in companies where the Company has the ability to exercise significant influence over operating&#13;and financial policies of the investee, at fair value. If the fair value method is applied to an investment that would otherwise be accounted&#13;for under the equity method of accounting, it is applied to all of the financial interests in the same entity that are eligible items&#13;(i.e., common stock and warrants). We elected the fair value method for our investment in Veritone, Inc. (&amp;#8220;Veritone&amp;#8221;) upon&#13;acquisition of the investment. As of March 31, 2021, we have no more investment in Veritone stocks and warrants.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&lt;b&gt;&amp;#160;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&lt;b&gt;Stock-Based Compensation&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;The compensation cost for all stock-based&#13;awards is measured at the grant date, based on the fair value of the award, and is recognized as an expense on a straight-line basis&#13;over the employee&amp;#8217;s requisite service period (generally the vesting period of the equity award) which is generally two to four&#13;years. The fair value of restricted stock and restricted stock unit awards is determined by the product of the number of shares or units&#13;granted and the grant date market price of the underlying common stock. The fair value of each option award is estimated on the date&#13;of grant using a Black-Scholes option-pricing model. Forfeitures are accounted for as they occur.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;Restricted stock units granted in September&#13;2019 with market-based vesting conditions vest based upon the Company achieving specified stock price targets over a three-year period.&#13;The effect of a market condition is reflected in the estimate of the grant-date fair value of the options utilizing a Monte Carlo valuation&#13;technique. Compensation cost is recognized with a market-based vesting condition provided that the requisite service is rendered, regardless&#13;of when, if ever, the market condition is satisfied. Assumptions utilized in connection with the Monte Carlo valuation technique included:&#13;estimated risk-free interest rate of 1.38 percent; term of 3.00 years; expected volatility of 38 percent; and expected dividend yield&#13;of 0 percent. The risk-free interest rate was determined based on the yields available on U.S. Treasury zero-coupon issues. The expected&#13;stock price volatility was determined using historical volatility. The expected dividend yield was based on expectations regarding dividend&#13;payments.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="font-family: Times New Roman, Times, Serif; color: Black"&gt;Profits&#13;Interest Units (&amp;#8220;Units&amp;#8221;) were accounted for in accordance with Accounting Standards Codification (&amp;#8220;ASC&amp;#8221;) 718-10,&#13;&amp;#8220;Compensation - Stock Compensation.&amp;#8221; The vesting conditions did not meet the definition of service, market or performance&#13;conditions, as defined in ASC 718. As such, the Units were classified as liability awards. Compensation expense was adjusted for changes&#13;in fair value prorated for the portion of the requisite service period rendered. Initially, compensation expense was recognized on a&#13;straight-line basis over the employee&amp;#8217;s requisite service period (generally the vesting period of the equity award) which was five&#13;years. Upon full vesting of the award, which occurred during the three months ended September 30, 2017, previously unrecognized compensation&#13;expense was immediately recognized in the period. The Company has a purchase option to purchase the vested Units that are not otherwise&#13;forfeited after termination of continuous service. The exercise price of the purchase option is the fair market value of the Units on&#13;the date of termination of continuous service. As of March 31, 2021, the Units totaled $591,000, which was their fair value as of December&#13;31, 2018 after termination of service.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&lt;b&gt;Series A Warrants&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&lt;b&gt;&amp;#160;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;The fair value of the Series A Warrants is estimated using a Black-Scholes&#13;option-pricing model. The fair value of the Series A Warrants as of March 31, 2021 was estimated based on the following assumptions:&#13;volatility of 30 percent, risk-free rate of 1.29 percent, term of 6.54 years and a dividend yield of 0 percent. Refer to Note 10 for&#13;additional information.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&lt;i&gt;&amp;#160;&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&lt;b&gt;Series B Warrants&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&lt;b&gt;&amp;#160;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;The fair value of the Series B Warrants is estimated using a Black-Scholes&#13;option-pricing model. In the quarter ended March 31, 2021, there was a change in methodology used to an acceptable Black-Scholes option-pricing&#13;model from a Monte Carlo valuation technique used to value the Series B Warrants as of December 31, 2020. The fair value of the Series&#13;B Warrants as of March 31, 2021 was estimated based on the following assumptions: (1) volatility of 30 percent, risk-free rate of 1.31&#13;percent, term of 6.63 years, and a dividend yield of 0 percent, and (2) volatility of 25 percent, risk-free rate of 0.11 percent, term&#13;of 1.4 years and a dividend yield of 0 percent. Refer to Note 10 for additional information.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&lt;b&gt;&amp;#160;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&lt;b&gt;Embedded derivatives&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&lt;i&gt;&amp;#160;&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;Embedded derivatives that are required&#13;to be bifurcated from their host contract are valued separately from the host instrument. The binomial model determines the value of&#13;a convertible bond instrument by valuing its two separate components (i.e., a cash only component which is subject to the selected risk-adjusted&#13;discount rate and an equity component where settlement is subject to a risk-free rate) within a single lattice framework. The binomial&#13;model utilizes the Tsiveriotis and Fernandes implementation in which a convertible instrument is split into two separate components:&#13;a cash-only component which is subject to the selected risk-adjusted discount rate and an equity component which is subject only to the&#13;risk-free rate. The model considers the (i) implied volatility of the value of our common stock, (ii) appropriate risk-free interest&#13;rate, (iii) credit spread, (iv) dividend yield, (v) dividend accrual (and a step-up in rates), and (vi) event probabilities of the various&#13;conversion and redemption scenarios.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;The volatility of the Company&amp;#8217;s common stock is estimated by&#13;analyzing the Company&amp;#8217;s historical volatility, implied volatility of publicly traded stock options, and the Company&amp;#8217;s current&#13;asset composition and financial leverage. The selected volatility, as described below, represents a haircut from the Company&amp;#8217;s&#13;actual realized historical volatility. A volatility haircut is a concept used to describe a commonly observed occurrence in which the&#13;volatility implied by market prices involving options, warrants, and convertible debt is lower than historical actual realized volatility.&#13;The assumed base case term used in the valuation model is the period remaining until November 15, 2027, the maturity date. The risk-free&#13;interest rate is based on the yield on the U.S. Treasury with a remaining term equal to the expected term of the conversion and early&#13;redemption options. The significant assumptions utilized in the Company&amp;#8217;s valuation of the embedded derivative at March 31, 2021&#13;are as follows: volatility of 30 percent, risk-free rate of 1.3 percent, discount rate of 8.8 percent, and a dividend yield of 0 percent.&#13;The fair value measurement of the embedded derivative is sensitive to these assumptions and changes in these assumptions could result&#13;in a materially different fair value measurement.

The applicable par value is deducted from the appropriate capital stock account&#13;on the formal or constructive retirement of treasury stock. Any excess of the cost of treasury stock over its par value is charged to&#13;additional paid-in capital and reflected as treasury stock on the condensed consolidated balance sheets.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&lt;b&gt;&amp;#160;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&lt;b&gt;Impairment of Investments&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;Acacia reviews its investments quarterly&#13;for indicators of other-than-temporary impairment. This determination requires significant judgment. In making this judgment, Acacia&#13;considers available quantitative and qualitative evidence in evaluating potential impairment of its investments. If the cost of an investment&#13;exceeds its fair value, Acacia evaluates, among other factors, general market conditions and the duration and extent to which the fair&#13;value is less than cost. Acacia also considers specific adverse conditions related to the financial health of and business outlook for&#13;the investee, including industry and sector performance, changes in technology, and operational and financing cash flow factors. Once&#13;a decline in fair value is determined to be other-than-temporary, an impairment charge is recorded in the condensed consolidated statements&#13;of operations and a new cost basis in the investment is established.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in"&gt;&lt;font style="color: Black"&gt;&lt;i&gt;&amp;#160;&lt;/i&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&lt;b&gt;Income Taxes&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&lt;i&gt;&amp;#160;&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;Income taxes are accounted for using an&#13;asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences&#13;of events that have been recognized in Acacia&amp;#8217;s condensed consolidated financial statements or consolidated income tax returns.&#13;A valuation allowance is established to reduce deferred tax assets if all, or some portion, of such assets will more than likely not&#13;be realized, or if it is determined that there is uncertainty regarding future realization of such assets.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;The provision for income taxes for interim&#13;periods is determined using an estimate of Acacia&amp;#8217;s annual effective tax rate, adjusted for discrete items, if any, that are taken&#13;into account in the relevant period. Each quarter, Acacia updates the estimate of the annual effective tax rate, and if the estimated&#13;tax rate changes, a cumulative adjustment is recorded.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;The Company&amp;#8217;s effective tax rates were (0%) and 11% for the&#13;three ended March 31, 2021 and 2020, respectively. Tax benefit (expense) for the periods presented primarily reflects the impact of state&#13;taxes and foreign taxes withholding or refund incurred on revenue agreements executed with third-party licensees domiciled in foreign&#13;jurisdictions. The Company has recorded full valuation allowance against our net deferred tax assets as of March 31, 2021 and 2020. These&#13;assets primarily consist of foreign tax credits, capital loss carryforwards and net operating loss carryforwards.&lt;/p&gt;</us-gaap:SignificantAccountingPoliciesTextBlock>

ASU&#13;2019-12 removes certain exceptions to the general principles in Topic 740 in Generally Accepted Accounting Principles. ASU 2019-12 is&#13;effective for public entities for fiscal years beginning after December 15, 2020, with early adoption permitted. The Company adopted ASU&#13;2019-12 as of January 1, 2021. The adoption of ASU 2019-12 did not have a material effect on the Company's current financial position,&#13;results of operations or financial statement disclosures.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&lt;i&gt;Recent Accounting Pronouncements &amp;#8211;&#13;Not Yet Adopted&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;In June 2016, the FASB issued ASU No. 2016-13,&#13;Financial Instruments&amp;#8212;Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, to replace the incurred&#13;loss methodology with an expected credit loss model that requires consideration of a broader range of information to estimate credit&#13;losses over the lifetime of the asset, including current conditions and reasonable and supportable forecasts in addition to historical&#13;loss information, to determine expected credit losses. Pooling of assets with similar risk characteristics and the use of a loss model&#13;are also required. Also, in April 2019, the FASB issued ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments&amp;#8212;Credit&#13;Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments, to clarify the inclusion of recoveries of trade receivables&#13;previously written off when estimating an allowance for credit losses. The amendments in this update will be effective for the Company&#13;in fiscal year 2023, with early adoption permitted. Management is currently evaluating the impact that the amendments in this update&#13;may have on the Company&amp;#8217;s condensed consolidated financial statements.&lt;/font&gt;&lt;/p&gt;</us-gaap:NewAccountingPronouncementsAndChangesInAccountingPrinciplesTextBlock>

The three-level hierarchy of valuation techniques established&#13;to measure fair value is defined as follows:&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;table cellspacing="0" cellpadding="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"&gt;&#13;  &lt;tr style="vertical-align: top"&gt;&#13;    &lt;td style="width: 96px"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;(i)&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;Level 1 - &lt;i&gt;Observable Inputs&lt;/i&gt;:&amp;#160;&amp;#160;Quoted&#13;    prices in active markets for identical investments;&lt;/font&gt;&lt;/td&gt;&lt;/tr&gt;&#13;  &lt;/table&gt;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;table cellspacing="0" cellpadding="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"&gt;&#13;  &lt;tr style="vertical-align: top"&gt;&#13;    &lt;td style="width: 96px"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;(ii)&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;Level 2 - &lt;i&gt;Pricing Models with Significant&#13;    Observable Inputs&lt;/i&gt;:&amp;#160;&amp;#160;Other significant observable inputs, including quoted prices for similar investments, interest&#13;    rates, credit risk, etc.; and&lt;/font&gt;&lt;/td&gt;&lt;/tr&gt;&#13;  &lt;/table&gt;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;table cellspacing="0" cellpadding="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"&gt;&#13;  &lt;tr style="vertical-align: top"&gt;&#13;    &lt;td style="width: 96px"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;(iii)&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;Level 3 - &lt;i&gt;Unobservable Inputs&lt;/i&gt;:&amp;#160;&amp;#160;Significant&#13;    unobservable inputs, including the entity&amp;#8217;s own assumptions in determining the fair value of investments.&lt;/font&gt;&lt;/td&gt;&lt;/tr&gt;&#13;  &lt;/table&gt;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;font style="color: Black"&gt;Whenever possible,&#13;the Company is required to use observable market inputs (Level 1 - quoted market prices) when measuring fair value. In such cases, the&#13;level at which the fair value measurement falls is determined based on the lowest level input that is significant to the fair value measurement.&#13;The assessment of the significance of a particular input requires judgment and considers factors specific to the asset or liability being&#13;measured.

Upon consummation of the&#13;approved investment in June 2020, the dividend rate increased to 8.0% on the stated value. Upon certain triggering events, the dividend&#13;rate will increase to 7.0% if the triggering event occurs before an approved investment or 10.0% on the stated value if the triggering&#13;event occurs after an approved investment.

Series A Redeemable Convertible Preferred Stock also participates on an as-converted&#13;basis in any regular or special dividends paid to common stockholders.

Proceeds received were allocated based on the fair value of the instrument without the Series A Warrants and of&#13;the Series A Warrants themselves at the time of issuance. The proceeds allocated to the Series A Redeemable Convertible Preferred Stock&#13;were then further allocated between the host preferred stock instrument and the embedded derivative, with the embedded derivative recorded&#13;at fair value and the Series A Redeemable Convertible Preferred Stock recorded at the residual amount. The portion of the proceeds allocated&#13;to the Series A Warrants, embedded derivative, and Series A Redeemable Convertible Preferred Stock was $4.8 million, $21.2 million, and&#13;$8.9 million, respectively. Transaction costs were also allocated between the Series A Redeemable Convertible Preferred Stock and the&#13;Series A Warrants on the same basis as the proceeds. The transaction costs allocated to the Series A Redeemable Convertible Preferred&#13;Stock were treated as a discount to the Series A Redeemable Convertible Preferred Stock. The transaction costs allocated to the Series&#13;A Warrants were expensed as incurred.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in; color: #7030A0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="color: Black"&gt;The Company classifies the Series A Redeemable&#13;Convertible Preferred Stock as mezzanine equity as the instrument will become redeemable at the option of the holder in various scenarios&#13;or otherwise on November 15, 2027. As it is probable that the Series A Redeemable Convertible Preferred Stock will become redeemable,&#13;the Company accretes the instrument to its redemption value using the effective interest method and recognizes any changes against additional&#13;paid in capital in the absence of retained earnings. Accretion for the three months ended March 31, 2021 was $853,000.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in; color: #7030A0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"&gt;&lt;font style="color: Black"&gt;In connection with the&#13;issuance of the Series A Redeemable Convertible Preferred Stock, the Company executed a Registration Rights Agreement with Starboard&#13;and the Buyers and a Governance Agreement with Starboard and certain affiliates of Starboard. Under the Registration Rights Agreement,&#13;the Company agreed to provide certain registration rights with respect to the Series A Redeemable Convertible Preferred Stock and shares&#13;of Common Stock issued upon conversion. In accordance with the Governance Agreement, the Company agreed to (i) increase the size of the&#13;Board of Directors from six to seven members, (ii) appoint Jonathan Sagal as a director of the Company, (iii) grant Starboard the right&#13;to recommend two additional directors for appointment to the board, (iv) form a Strategic Committee of the Board tasked with sourcing&#13;and performing due diligence on potential acquisition targets, (v) appoint certain directors to the Strategic Committee, and (vi) appoint&#13;a director to the Nominating and Corporate Governance Committee.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"&gt;&lt;font style="color: Black"&gt;The following features&#13;of the Series A Redeemable Convertible Preferred Stock are required to be bifurcated from the host preferred stock and accounted for&#13;separately as an embedded derivative: (i) the right of the holders to redeem the shares (the &amp;#8220;put option&amp;#8221;), (ii) the right&#13;of the holders to receive common stock upon conversion of the shares (the &amp;#8220;conversion option&amp;#8221;), (iii) the right of the Company&#13;to redeem the shares (the &amp;#8220;call option&amp;#8221;), and (iv) the change in dividend rate upon consummation of an approved investment&#13;or a triggering event (the &amp;#8220;contingent dividend rate feature&amp;#8221;).&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in; color: #7030A0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"&gt;&lt;font style="color: Black"&gt;These features are required&#13;to be accounted for separately from the Series A Redeemable Convertible Preferred Stock because the features were determined to be not&#13;clearly and closely related to the debt-like host and also did not meet any other scope exceptions for derivative accounting. Therefore,&#13;these features are bundled together and are accounted for as a single, compound embedded derivative liability.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in; color: #7030A0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"&gt;&lt;font style="color: Black"&gt;Accordingly, we have recorded&#13;an embedded derivative liability representing the combined fair value of each of these features. The embedded derivative liability is&#13;adjusted to reflect fair value at each period end with changes in fair value recorded in the &amp;#8220;Change in fair value of redeemable&#13;preferred stock embedded derivative&amp;#8221; financial statement line item of the accompanying consolidated statements of operations. As&#13;of March 31, 2021, the fair value of the Series A embedded derivative was $40.4 million.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"&gt;&lt;font style="color: Black"&gt;&lt;i&gt;Series A Warrants&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;On November 18, 2019, in connection with the issuance of the Series&#13;A Redeemable Convertible Preferred Stock, the Company issued a detachable Series A Warrants to acquire up to purchase 5,000,000 shares&#13;of common stock at a price of $3.65 per share (subject to certain anti-dilution adjustments) at any time during a period of eight years&#13;beginning on the instrument&amp;#8217;s issuance date of the Series A Warrants. The fair value of the Series A Warrants was $4.8 million.&#13;The Series A Warrants will be recognized at fair value at each reporting period until exercised, with changes in fair value recognized&#13;in other income (expense) in the accompanying consolidated statements of operations.

Per the Supplemental Agreement, interest is payable semiannually&#13;at a rate of 6.00% per annum, and in an event of default, the interest rate is increased to 10% per annum. The Notes include certain&#13;financial and non-financial covenants. Additionally, all or any portion of the principal amount outstanding under the Notes may, at the&#13;election of Starboard, be surrendered to the Company for cancellation in payment of the exercise price upon the exercise of Series B&#13;Warrants.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in; color: #7030A0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"&gt;&lt;font style="color: Black"&gt;On&#13;June 30, 2020, the Company entered into an Exchange Agreement (the &amp;#8220;Exchange Agreement&amp;#8221;) with Merton Acquisition HoldCo LLC,&#13;a Delaware limited liability company and wholly-owned subsidiary of the Company (&amp;#8220;Merton&amp;#8221;) and Starboard, on behalf of itself&#13;and on behalf of certain funds and accounts under its management, including the holders of the Notes. Pursuant to the Exchange Agreement,&#13;the holders of the Notes exchanged the entire outstanding principal amount for new senior notes (the &amp;#8220;New Notes&amp;#8221;) issued&#13;by Merton having an aggregate outstanding original principal amount of $115 million.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in; color: #7030A0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"&gt;&lt;font style="color: Black"&gt;The&#13;New Notes bear interest at a rate of 6.00% per annum and had a maturity date of December 31, 2020. The New Notes are fully guaranteed&#13;by the Company and are secured by an all-assets pledge of the Company and Merton and non-recourse equity pledges of each of the Company&amp;#8217;s&#13;material subsidiaries. Pursuant to the Exchange Agreement, the New Notes (i) are deemed to be &amp;#8220;Notes&amp;#8221; for purposes of the&#13;Securities Purchase Agreement, (ii) are deemed to be &amp;#8220;June 2020 Approved Investment Notes&amp;#8221; for purposes of the Supplemental&#13;Agreement, and therefore the Company has agreed to redeem $80 million principal amount of the New Notes by September 30, 2020 and $35&#13;million principal amount of the New Notes by December 31, 2020, and (iii) are deemed to be &amp;#8220;Notes&amp;#8221; for the purposes of the&#13;Series B Warrants, and therefore may be tendered pursuant to a Note Cancellation under the Series B Warrants on the terms set forth in&#13;the Series B Warrants and the New Notes. Delivery of notes in the form of the New Notes will also satisfy the delivery of Exchange Notes&#13;pursuant to Section 16(i) of the Certificate of Designations of the Company&amp;#8217;s Series A Convertible Preferred Stock, par value $0.001&#13;per share. The New Notes will not be deemed to be &amp;#8220;Notes&amp;#8221; for the purposes of the Registration Rights Agreement, dated as&#13;of November 18, 2019, by and among the Company, Starboard and the Buyers.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in; color: #7030A0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"&gt;&lt;font style="color: Black"&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;Because the New Notes are to be settled within twelve months pursuant&#13;to their terms, they are classified as current liabilities on the balance sheet. The Company capitalized $4.6 million in lender fees&#13;and $0.5 million in other issuance costs associated with the issuance of the Notes. The $4.6 million of lender fees are recognized as&#13;long term deferred debt issuance cost and will be amortized to interest expense until November 15, 2027, the maturity date of Series&#13;A Redeemable Convertible Preferred Stock. The $0.5 million issuance costs are recognized as a discount on the Notes and will be amortized&#13;to interest expense over the contractual life of the Notes. There is $1.5 million accrued and unpaid interest on the New Note as of March&#13;31, 2021.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in; color: #7030A0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;On January 29, 2021, the Company redeemed $50 million of the New Notes.&#13;On March 31, 2021, the Company reissued $50 million of the New Notes for a total principal amount outstanding of New Notes as of March&#13;31, 2021 of $115 million and the parties agreed that the Company will redeem the remaining $115 million of the principal amount of the&#13;New Notes on or before July 15, 2021.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; color: #7030A0"&gt;&lt;font style="color: Black"&gt;&lt;i&gt;Modifications&#13;to Series A Redeemable Convertible Preferred Stock and Series B Warrants&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; color: #7030A0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"&gt;&lt;font style="color: Black"&gt;The&#13;June 4, 2020 Supplemental Agreement also provided for (i) a waiver of increased dividends under the original terms of the Series A Redeemable&#13;Convertible Preferred Stock that would have otherwise accrued due to the Company&amp;#8217;s use of the $35 million proceeds received from&#13;Starboard and the Buyers upon the issuance of the Series A Redeemable Convertible Preferred Stock in November 2019, (ii) the replacement&#13;of original optional redemption rights for the Series A Redeemable Convertible Preferred Stock provided to both the Company and the holders&#13;that otherwise would have been nullified through the issuance of the Notes, and (iii) an amendment to the terms of the previously issued&#13;Series B Warrants to permit the payment of the lower exercise price of $3.65 through the payment of cash, rather than only through the&#13;cancellation of Notes outstanding, at any time until the expiration of the Series B Warrants on November 15, 2027. Only 31,506,849 of&#13;the Series B Warrants are subject to this adjustment with the remaining balance of 68,493,151 Series B Warrants continuing under their&#13;original terms.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"&gt;&lt;font style="color: Black"&gt;We&#13;analyzed the amendments to the terms of the Series A Redeemable Convertible Preferred Stock and determined that the amendments were not&#13;significant.

As of March 31, 2021, $1,133,000 was amortized to interest expense.

Pursuant to the Transaction Agreement,&#13;the Company agreed to purchase from Seller and Seller agreed to transfer to the Company the specified equity securities of all Portfolio&#13;Companies at set prices at various future dates. The transfer dates would vary among the Portfolio Companies as the Transaction Agreement&#13;gives the Company the exclusive right to determine when to call for transfer of each security, and because each Portfolio Company (or&#13;its existing equity holders) may be required to approve the transfer due to rights of first refusals and other company-specific terms&#13;and conditions. Thus, the execution of the Transaction Agreement resulted in forward contracts for the Company to purchase equity securities&#13;in each public and private company at a specified price on a future date.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in; color: #7030A0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"&gt;&lt;font style="color: Black"&gt;In accordance with the&#13;Transaction Agreement, the Company transferred the total purchase price of &amp;#163;223.9 million into an escrow account. Upon the transfer&#13;of equity securities in the Portfolio Companies to the Company, the associated funds were released from the escrow account to Seller&#13;based on the consideration amount assigned to the equity securities for such Portfolio Companies in the Transaction Agreement. As of&#13;December 31, 2020, all of the equity securities in the Portfolio Companies were transferred to the Company pursuant to the Transaction&#13;Agreement. The Company has sold a portion of the equity securities of such Portfolio Companies while retaining an interest in a number&#13;of operating businesses, including a controlling interest in one of the Portfolio Companies.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in; color: #7030A0"&gt;&lt;font style="color: Black"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"&gt;&lt;font style="color: Black"&gt;For accounting purposes,&#13;the total purchase price of the portfolio was allocated to the individual equity securities based on their individual fair values as&#13;of April 3, 2020, in order to establish an appropriate cost basis for each of the acquired securities. The fair values of the public&#13;company securities were based on their quoted market price.

The acquisition of the MalinJ1 securities was accounted for as&#13;an asset acquisition as there was a change of control of MalinJ1 and substantially all of the fair value of the assets acquired was concentrated&#13;in a single identifiable asset, an investment in Viamet Pharmaceuticals Holdings, LLC (&amp;#8220;Viamet&amp;#8221;). As such the cost basis&#13;of the MalinJ1 securities was used to allocate to the Viamet investment, the single identifiable asset, and no goodwill was recognized.&#13;The Company through its consolidation of MalinJ1 accounts for the Viamet investment under the equity method as it owns 37.9% of outstanding&#13;shares of Viamet.&lt;/font&gt;&lt;/p&gt;</us-gaap:InvestmentsInDebtAndMarketableEquitySecuritiesAndCertainTradingAssetsDisclosureTextBlock>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><font style="color: Black">Acacia was incorporated on January 25,
1993 under the laws of the State of California. In December 1999, Acacia changed its state of incorporation from California to Delaware.</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><font style="color: Black">&#160;</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><font style="color: Black">Acacia acquires businesses and operating
assets that the Company believes to be undervalued and where the Company believes it can leverage its resources and skill sets to realize
and unlock value. The Company intends to leverage its (i) access to flexible capital that can be deployed unconditionally, (ii) expertise
in corporate governance and operational restructuring, (iii) willingness to invest in out of favor industries and businesses that suffer
from a complexity discount and untangle complex, multi-factor situations, and (iv) expertise and relationships in certain sectors, to
complete strategic acquisitions of businesses, divisions, and/or assets with a focus on mature technology, healthcare, industrial and
certain financial segments. Acacia seeks to identify opportunities where the Company believes it is an advantaged buyer, where the Company
can avoid structured sale processes and create the opportunity to purchase businesses, divisions and/or assets of companies at an attractive
price due to the Company&#8217;s unique capabilities, relationships, or expertise, or where Acacia believes the target would be worth
more to the Company than to other buyers.</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><font style="color: Black">&#160;</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><font style="color: Black">Acacia operates its business based on three
key principles of People, Process and Performance and have built a management team with identified expertise in Research, Execution and
Operation of the Company&#8217;s targeted acquisitions.</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"><font style="color: Black">&#160;</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><font style="color: Black">Acacia, through its operating subsidiaries,
also currently engages in its legacy business of investing in, licensing and enforcing patented technologies. Acacia&#8217;s operating
subsidiaries partner with inventors and patent owners, applying their legal and technology expertise to patent assets to unlock the financial
value in their patented inventions. In recent years, Acacia has also invested in technology companies. Acacia leverages its experience,
expertise, data and relationships developed as a leader in the intellectual property (&#8220;IP&#8221;) industry to pursue these opportunities.
In some cases, these opportunities will complement and/or supplement Acacia&#8217;s primary licensing and enforcement business.</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><font style="color: Black">&#160;</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><font style="color: Black">Acacia&#8217;s operating subsidiaries generate
revenues and related cash flows from the granting of IP rights (hereinafter, &#8220;IP Rights&#8221;) for the use of patented technologies
that its operating subsidiaries control or own. Acacia&#8217;s operating subsidiaries assist patent owners with the prosecution and development
of their patent portfolios, the protection of their patented inventions from unauthorized use, the generation of licensing revenue from
users of their patented technologies and, where necessary, with the enforcement against unauthorized users of their patented technologies
through the filing of patent infringement litigation.</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"><font style="color: Black">&#160;</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><font style="color: Black">Acacia&#8217;s operating subsidiaries are
principals in the licensing and enforcement effort, obtaining control of the rights in the patent portfolio, or control of the patent
portfolio outright. Acacia&#8217;s operating subsidiaries own or control the rights to multiple patent portfolios, which include U.S.
patents and certain foreign counterparts, covering technologies used in a wide variety of industries.</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><font style="color: Black">Neither Acacia nor its operating subsidiaries
invent new technologies or products; rather, Acacia depends upon the identification and investment in new patents, inventions and companies
that own IP through its relationships with inventors, universities, research institutions, technology companies and others. If Acacia&#8217;s
operating subsidiaries are unable to maintain those relationships and identify and grow new relationships, then they may not be able
to identify new technology-based opportunities for sustainable revenue and/or revenue growth.</font></p>

GAAP&#8221;) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly,
certain information and footnotes required by U.S. GAAP in annual financial statements have been omitted or condensed in accordance with
quarterly reporting requirements of the Securities and Exchange Commission (&#8220;SEC&#8221;). These interim unaudited condensed consolidated
financial statements should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December
31, 2020, as reported by Acacia in its Annual Report on Form 10-K filed with the SEC on March 29, 2021, as well as in our other public
filings with the SEC. The condensed consolidated interim financial statements of Acacia include all adjustments of a normal recurring
nature which, in the opinion of management, are necessary for a fair statement of Acacia&#8217;s consolidated financial position as of
March 31, 2021, and results of its operations and its cash flows for the interim periods presented. The consolidated results of operations
for the three months ended March 31, 2021 are not necessarily indicative of the results to be expected for the entire fiscal year.</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><font style="color: Black">&#160;</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><font style="color: Black">The preparation of financial statements
in conformity with generally accepted accounting principles in the United States of America requires management to make estimates and
assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date
of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results
could differ from these estimates. Acacia believes that, of the significant accounting policies described herein, the accounting policies
associated with revenue recognition, the valuation of the equity instruments, the valuation of Series A redeemable convertible preferred
stock (the &#8220;Series A Redeemable Convertible Preferred Stock&#8221;), embedded derivatives, Series A warrants (the &#8220;Series
A Warrants&#8221;), Series B warrants (the &#8220;Series B Warrants&#8221;), stock-based compensation expense, impairment of patent-related
intangible assets, the determination of the economic useful life of amortizable intangible assets, income taxes and valuation allowances
against net deferred tax assets, require its most difficult, subjective or complex judgments.</font></p>

continues to evolve as of the date of this report. While the Company does not expect the current situation to present direct risks to
its business, and it has not had a material impact to date, the COVID-19 pandemic could adversely impact the Company&#8217;s operations,
as well as the operations of its licensees and other business partners. Our cash is held in major financial institutions in government
instruments and high-quality short-term bonds. Our business is fully able to operate in a socially distanced and/or remote capacity and
in accordance with applicable laws, policies, and best practices. Our workforce is provided ample paid sick leave, and we have in place
robust disaster recovery and business continuity policies that have been revised to account for a long-term remote work contingency such
as this. However, the ongoing pandemic may present risks that we do not currently consider material or risks that may evolve quickly
that could have a materially adverse effect on our business, results of operations and financial condition.</font></p>

Coronavirus Aid, Relief and Economic Security Act (&#34;CARES Act&#34;) was signed into law on March 27, 2020. The CARES Act, among
other things, includes tax provisions relating to refundable payroll tax credits, deferment of employer's social security payments, net
operating loss utilization and carryback periods and modifications to the net interest deduction limitations. The CARES Act has not had
a material impact on the Company&#8217;s income tax provision.</font></p>

the United States signed the Consolidated Appropriations Act, 2021 (&#8220;Consolidated Appropriations Act&#8221;) into law. The Consolidated
Appropriations Act is intended to enhance and expand certain provisions of the CARES Act, allows for the deductions of expenses related
to the Payroll Protection Program funds received by companies, and provides an update to meals and entertainment expensing for 2021.
The Consolidated Appropriations Act did not have a material impact to the Company&#8217;s income tax provision for 2020. The Company
will continue to evaluate the impact of the Consolidated Appropriations Act on its financial position, results of operations and cash
flows, if any.</font></p><span></span>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><font style="color: Black"><i>&#160;</i></font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"><font style="color: Black">Revenue is recognized upon
transfer of control of promised bundled IP Rights and other contractual performance obligations to licensees in an amount that reflects
the consideration we expect to receive in exchange for those IP Rights. Revenue contracts that provide promises to grant the right to
use IP Rights as they exist at the point in time at which the IP Rights are granted, are accounted for as performance obligations satisfied
at a point in time and revenue is recognized at the point in time that the applicable performance obligations are satisfied and all other
revenue recognition criteria have been met.</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in; color: #7030A0"><font style="color: Black">&#160;</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"><font style="color: Black">For the periods presented,
revenue contracts executed by the Company primarily provided for the payment of contractually determined, one-time, paid-up license fees
in consideration for the grant of certain IP Rights for patented technologies owned or controlled by Acacia. Revenues also included license
fees from sales-based revenue contracts, the majority of which were originally executed in prior periods, which provide for the payment
of quarterly license fees based on quarterly sales of applicable product units by licensees (&#8220;Recurring Revenue Agreements&#8221;).
Revenues may also include court ordered settlements or awards related to our patent portfolio or sales of our patent portfolio. IP Rights
granted included the following, as applicable: (i) the grant of a non-exclusive, retroactive and future license to manufacture and/or
sell products covered by patented technologies, (ii) a covenant-not-to-sue, (iii) the release of the licensee from certain claims, and
(iv) the dismissal of any pending litigation. The IP Rights granted were perpetual in nature, extending until the legal expiration date
of the related patents. The individual IP Rights are not accounted for as separate performance obligations, as (i) the nature of the
promise, within the context of the contract, is to transfer combined items to which the promised IP Rights are inputs and (ii) the Company's
promise to transfer each individual IP right described above to the customer is not separately identifiable from other promises to transfer
IP Rights in the contract.</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in; color: #7030A0"><font style="color: Black">&#160;</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"><font style="color: Black">Since the promised IP Rights
are not individually distinct, the Company combined each individual IP Right in the contract into a bundle of IP Rights that is distinct,
and accounted for all of the IP Rights promised in the contract as a single performance obligation. The IP Rights granted were &#8220;functional
IP rights&#8221; that have significant standalone functionality. Acacia's subsequent activities do not substantively change that functionality
and do not significantly affect the utility of the IP to which the licensee has rights. Acacia&#8217;s operating subsidiaries have no
further obligation with respect to the grant of IP Rights, including no express or implied obligation to maintain or upgrade the technology,
or provide future support or services. The contracts provide for the grant (i.e., transfer of control) of the licenses, covenants-not-to-sue,
releases, and other significant deliverables upon execution of the contract. Licensees legally obtain control of the IP Rights upon execution
of the contract. As such, the earnings process is complete and revenue is recognized upon the execution of the contract, when collectability
is probable and all other revenue recognition criteria have been met. Revenue contracts generally provide for payment of contractual
amounts with 30-90 days of execution of the contract, or the end of the quarter in which the sale or usage occurs for Recurring Revenue
Agreements. Contractual payments made by licensees are generally non-refundable.</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"><font style="color: Black">For sales-based royalties,
the Company includes in the transaction price some or all of an amount of estimated variable consideration to the extent that it is probable
that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable
consideration is subsequently resolved. Notwithstanding, revenue is recognized for a sales-based royalty promised in exchange for a license
of IP Rights when the later of (i) the subsequent sale or usage occurs, or (ii) the performance obligation to which some or all of the
sales-based royalty has been allocated has been satisfied. Estimates are generally based on historical levels of activity, if available.</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"><font style="color: Black">Revenues from contracts
with significant financing components (either explicit or implicit) are recognized at an amount that reflects the price that a licensee
would have paid if the licensee had paid cash for the IP Rights when they transfer to the licensee. In determining the transaction price,
the Company adjusts the promised amount of consideration for the effects of the time value of money. As a practical expedient, the Company
does not adjust the promised amount of consideration for the effects of a significant financing component if the Company expects, at
contract inception, that the period between when the entity transfers promised IP Rights to a customer and when the customer pays for
the IP Rights will be one year or less.</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"><font style="color: Black">In general, the Company
is required to make certain judgments and estimates in connection with the accounting for revenue contracts with customers. Such areas
may include identifying performance obligations in the contract, estimating the timing of satisfaction of performance obligations, determining
whether a promise to grant a license is distinct from other promised goods or services, evaluating whether a license transfers to a customer
at a point in time or over time, allocating the transaction price to separate performance obligations, determining whether contracts
contain a significant financing component, and estimating revenues recognized at a point in time for sales-based royalties.</font></p>

value over its fair value. If an asset is determined to be impaired, the loss is measured based on quoted market prices in active markets,

cash outflows are based on existing contractual obligations, such as contingent legal fee and inventor royalty obligations, applied to
estimated license fee revenues, in addition to other estimates of out-of-pocket expenses associated with a specific patent portfolio&#8217;s

The effect of a market condition is reflected in the estimate of the grant-date fair value of the options utilizing a Monte Carlo valuation
technique. Compensation cost is recognized with a market-based vesting condition provided that the requisite service is rendered, regardless
of when, if ever, the market condition is satisfied. Assumptions utilized in connection with the Monte Carlo valuation technique included:
estimated risk-free interest rate of 1.38 percent; term of 3.00 years; expected volatility of 38 percent; and expected dividend yield
of 0 percent. The risk-free interest rate was determined based on the yields available on U.S. Treasury zero-coupon issues. The expected
stock price volatility was determined using historical volatility. The expected dividend yield was based on expectations regarding dividend
payments.</font></p>

conditions, as defined in ASC 718. As such, the Units were classified as liability awards. Compensation expense was adjusted for changes
in fair value prorated for the portion of the requisite service period rendered. Initially, compensation expense was recognized on a
straight-line basis over the employee&#8217;s requisite service period (generally the vesting period of the equity award) which was five
years. Upon full vesting of the award, which occurred during the three months ended September 30, 2017, previously unrecognized compensation
expense was immediately recognized in the period. The Company has a purchase option to purchase the vested Units that are not otherwise
forfeited after termination of continuous service. The exercise price of the purchase option is the fair market value of the Units on
the date of termination of continuous service. As of March 31, 2021, the Units totaled $591,000, which was their fair value as of December

to be bifurcated from their host contract are valued separately from the host instrument. The binomial model determines the value of
a convertible bond instrument by valuing its two separate components (i.e., a cash only component which is subject to the selected risk-adjusted
discount rate and an equity component where settlement is subject to a risk-free rate) within a single lattice framework. The binomial
model utilizes the Tsiveriotis and Fernandes implementation in which a convertible instrument is split into two separate components:
a cash-only component which is subject to the selected risk-adjusted discount rate and an equity component which is subject only to the
risk-free rate. The model considers the (i) implied volatility of the value of our common stock, (ii) appropriate risk-free interest
rate, (iii) credit spread, (iv) dividend yield, (v) dividend accrual (and a step-up in rates), and (vi) event probabilities of the various
conversion and redemption scenarios.</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">The volatility of the Company&#8217;s common stock is estimated by
analyzing the Company&#8217;s historical volatility, implied volatility of publicly traded stock options, and the Company&#8217;s current
asset composition and financial leverage. The selected volatility, as described below, represents a haircut from the Company&#8217;s
actual realized historical volatility. A volatility haircut is a concept used to describe a commonly observed occurrence in which the
volatility implied by market prices involving options, warrants, and convertible debt is lower than historical actual realized volatility.
The assumed base case term used in the valuation model is the period remaining until November 15, 2027, the maturity date. The risk-free
interest rate is based on the yield on the U.S. Treasury with a remaining term equal to the expected term of the conversion and early
redemption options. The significant assumptions utilized in the Company&#8217;s valuation of the embedded derivative at March 31, 2021
are as follows: volatility of 30 percent, risk-free rate of 1.3 percent, discount rate of 8.8 percent, and a dividend yield of 0 percent.
The fair value measurement of the embedded derivative is sensitive to these assumptions and changes in these assumptions could result
in a materially different fair value measurement. Refer to Note 10 for additional information.</p>

for indicators of other-than-temporary impairment. This determination requires significant judgment. In making this judgment, Acacia
considers available quantitative and qualitative evidence in evaluating potential impairment of its investments. If the cost of an investment
exceeds its fair value, Acacia evaluates, among other factors, general market conditions and the duration and extent to which the fair
value is less than cost. Acacia also considers specific adverse conditions related to the financial health of and business outlook for
the investee, including industry and sector performance, changes in technology, and operational and financing cash flow factors. Once
a decline in fair value is determined to be other-than-temporary, an impairment charge is recorded in the condensed consolidated statements
of operations and a new cost basis in the investment is established.</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><font style="color: Black">Income taxes are accounted for using an
asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences
of events that have been recognized in Acacia&#8217;s condensed consolidated financial statements or consolidated income tax returns.
A valuation allowance is established to reduce deferred tax assets if all, or some portion, of such assets will more than likely not
be realized, or if it is determined that there is uncertainty regarding future realization of such assets.</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><font style="color: Black">The provision for income taxes for interim
periods is determined using an estimate of Acacia&#8217;s annual effective tax rate, adjusted for discrete items, if any, that are taken
into account in the relevant period. Each quarter, Acacia updates the estimate of the annual effective tax rate, and if the estimated
tax rate changes, a cumulative adjustment is recorded.</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in"><font style="color: Black">&#160;</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">The Company&#8217;s effective tax rates were (0%) and 11% for the
three ended March 31, 2021 and 2020, respectively. Tax benefit (expense) for the periods presented primarily reflects the impact of state
taxes and foreign taxes withholding or refund incurred on revenue agreements executed with third-party licensees domiciled in foreign
jurisdictions. The Company has recorded full valuation allowance against our net deferred tax assets as of March 31, 2021 and 2020. These
assets primarily consist of foreign tax credits, capital loss carryforwards and net operating loss carryforwards.</p><span></span>

Acacia Entities, Monarch Networking Solutions LLC (&#8220;Monarch&#8221;), Acacia board member Katharine Wolanyk, and Transpacific IP
Group, Ltd., or Transpacific. Slingshot alleges that the Acacia Entities and Monarch misappropriated its confidential and proprietary
information, purportedly furnished to the Acacia Entities and Monarch by Ms. Wolanyk, in acquiring a patent portfolio from Transpacific
after Slingshot&#8217;s exclusive option to purchase the same patent portfolio from Transpacific had already expired. Slingshot seeks
monetary damages, as well as equitable and injunctive relief related to its alleged right to own the portfolio. On March 15, 2021, the
court issued orders granting Monarch&#8217;s motion to dismiss for lack of personal jurisdiction and Ms. Wolanyk&#8217;s motion to dismiss
for lack of subject matter jurisdiction. The Acacia Entities maintain that Slingshot&#8217;s allegations are baseless, that the Acacia
Entities neither had access to nor used Slingshot&#8217;s information in acquiring the portfolio, that the Acacia Entities acquired the
portfolio as a result of the independent efforts of its IP licensing group, and that Slingshot suffered no damages given its exclusive
option to purchase the portfolio had already ended and it has proven itself incapable of closing on the portfolio purchase.<font style="font-family: Times New Roman, Times, Serif"></font></font></p>

common stock, Acacia&#8217;s Board of Directors consider such factors, among others, as the impact of the repurchase on Acacia&#8217;s
cash position, as well as Acacia&#8217;s capital needs and whether there is a better alternative use of Acacia&#8217;s capital. Acacia
has no obligation to repurchase any amount of its common stock under the Stock Repurchase Program. Repurchases to date were made in the

stock from acquiring additional shares of the Company&#8217;s common stock (subject to certain exceptions). There is no guarantee, however,

common stock that could result in an ownership change. Like the Plan, the purpose of the Charter Provision is to protect the Company&#8217;s
ability to utilize potential tax assets, such as net operating loss carryforwards and tax credits to offset potential future taxable
income. The Charter Provision was approved by the Company&#8217;s stockholders on July 15, 2019.</font></p><span></span>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">In December of 2019, the Financial Accounting Standards Board (&#8220;FASB&#8221;)
issued ASU No. 2019-12, &#34;Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes&#34; (&#34;ASU 2019-12&#34;). ASU
2019-12 removes certain exceptions to the general principles in Topic 740 in Generally Accepted Accounting Principles. ASU 2019-12 is
effective for public entities for fiscal years beginning after December 15, 2020, with early adoption permitted. The Company adopted ASU
2019-12 as of January 1, 2021. The adoption of ASU 2019-12 did not have a material effect on the Company's current financial position,
results of operations or financial statement disclosures.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><font style="color: Black">In June 2016, the FASB issued ASU No. 2016-13,
Financial Instruments&#8212;Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, to replace the incurred
loss methodology with an expected credit loss model that requires consideration of a broader range of information to estimate credit
losses over the lifetime of the asset, including current conditions and reasonable and supportable forecasts in addition to historical
loss information, to determine expected credit losses. Pooling of assets with similar risk characteristics and the use of a loss model
are also required. Also, in April 2019, the FASB issued ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments&#8212;Credit
Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments, to clarify the inclusion of recoveries of trade receivables
previously written off when estimating an allowance for credit losses. The amendments in this update will be effective for the Company
in fiscal year 2023, with early adoption permitted. Management is currently evaluating the impact that the amendments in this update
may have on the Company&#8217;s condensed consolidated financial statements.</font></p><span></span>

that would be received for an asset or the exit price that would be paid to transfer a liability in the principal or most advantageous
market in an orderly transaction between market participants on the measurement date, and also establishes a fair value hierarchy which
requires an entity to maximize the use of observable inputs, where available. The three-level hierarchy of valuation techniques established
to measure fair value is defined as follows:</font></p>

the Company is required to use observable market inputs (Level 1 - quoted market prices) when measuring fair value. In such cases, the
level at which the fair value measurement falls is determined based on the lowest level input that is significant to the fair value measurement.
The assessment of the significance of a particular input requires judgment and considers factors specific to the asset or liability being
measured. In certain cases, inputs used to measure fair value fall into different levels of the fair value hierarchy.</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"><font style="color: Black">On April 3, 2020, the Company
entered into an Option Agreement with Seller, which included general terms through which the Company was provided the option to purchase
life sciences equity securities in a portfolio of public and private companies (&#8220;Portfolio Companies&#8221;) for an aggregate purchase
price of &#163;223.9 million, approximately $277.5 million at the exchange rate on April 3, 2020.</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #7030A0"><font style="color: Black">On June 4, 2020, the Company
executed the Transaction Agreement between Link Fund Solutions Limited, Seller, and the Company. Pursuant to the Transaction Agreement,
the Company agreed to purchase from Seller and Seller agreed to transfer to the Company the specified equity securities of all Portfolio
Companies at set prices at various future dates. The transfer dates would vary among the Portfolio Companies as the Transaction Agreement
gives the Company the exclusive right to determine when to call for transfer of each security, and because each Portfolio Company (or
its existing equity holders) may be required to approve the transfer due to rights of first refusals and other company-specific terms
and conditions. Thus, the execution of the Transaction Agreement resulted in forward contracts for the Company to purchase equity securities
in each public and private company at a specified price on a future date.</font></p>

Transaction Agreement, the Company transferred the total purchase price of &#163;223.9 million into an escrow account. Upon the transfer
of equity securities in the Portfolio Companies to the Company, the associated funds were released from the escrow account to Seller
based on the consideration amount assigned to the equity securities for such Portfolio Companies in the Transaction Agreement. As of
December 31, 2020, all of the equity securities in the Portfolio Companies were transferred to the Company pursuant to the Transaction
Agreement. The Company has sold a portion of the equity securities of such Portfolio Companies while retaining an interest in a number
of operating businesses, including a controlling interest in one of the Portfolio Companies.</font></p>

the total purchase price of the portfolio was allocated to the individual equity securities based on their individual fair values as
of April 3, 2020, in order to establish an appropriate cost basis for each of the acquired securities. The fair values of the public
company securities were based on their quoted market price. The fair values of the private company securities were estimated based on
recent financing transactions and secondary market transactions and factoring in a discount for the illiquidity of these securities.</font></p>

Company&#8217;s acquisition of equity securities in the Portfolio Companies, the Company acquired a majority interest in the equity securities
of MalinJ1, which were transferred to the Company on December 3, 2020. The acquisition of the MalinJ1 securities was accounted for as
an asset acquisition as there was a change of control of MalinJ1 and substantially all of the fair value of the assets acquired was concentrated
in a single identifiable asset, an investment in Viamet Pharmaceuticals Holdings, LLC (&#8220;Viamet&#8221;). As such the cost basis
of the MalinJ1 securities was used to allocate to the Viamet investment, the single identifiable asset, and no goodwill was recognized.
The Company through its consolidation of MalinJ1 accounts for the Viamet investment under the equity method as it owns 37.9% of outstanding
shares of Viamet.</font></p><span></span>

assets that the Company believes to be undervalued and where the Company believes it can leverage its resources and skill sets to realize

from a complexity discount and untangle complex, multi-factor situations, and (iv) expertise and relationships in certain sectors, to
complete strategic acquisitions of businesses, divisions, and/or assets with a focus on mature technology, healthcare, industrial and
certain financial segments. Acacia seeks to identify opportunities where the Company believes it is an advantaged buyer, where the Company
can avoid structured sale processes and create the opportunity to purchase businesses, divisions and/or assets of companies at an attractive
price due to the Company&#8217;s unique capabilities, relationships, or expertise, or where Acacia believes the target would be worth
more to the Company than to other buyers.</font></p>

also currently engages in its legacy business of investing in, licensing and enforcing patented technologies. Acacia&#8217;s operating
subsidiaries partner with inventors and patent owners, applying their legal and technology expertise to patent assets to unlock the financial
value in their patented inventions. In recent years, Acacia has also invested in technology companies. Acacia leverages its experience,
expertise, data and relationships developed as a leader in the intellectual property (&#8220;IP&#8221;) industry to pursue these opportunities.
In some cases, these opportunities will complement and/or supplement Acacia&#8217;s primary licensing and enforcement business.</font></p>

revenues and related cash flows from the granting of IP rights (hereinafter, &#8220;IP Rights&#8221;) for the use of patented technologies
that its operating subsidiaries control or own. Acacia&#8217;s operating subsidiaries assist patent owners with the prosecution and development
of their patent portfolios, the protection of their patented inventions from unauthorized use, the generation of licensing revenue from
users of their patented technologies and, where necessary, with the enforcement against unauthorized users of their patented technologies
through the filing of patent infringement litigation.</font></p>

patents and certain foreign counterparts, covering technologies used in a wide variety of industries.</font></p>

invent new technologies or products; rather, Acacia depends upon the identification and investment in new patents, inventions and companies
that own IP through its relationships with inventors, universities, research institutions, technology companies and others. If Acacia&#8217;s
operating subsidiaries are unable to maintain those relationships and identify and grow new relationships, then they may not be able
to identify new technology-based opportunities for sustainable revenue and/or revenue growth.</font></p>

transfer of control of promised bundled IP Rights and other contractual performance obligations to licensees in an amount that reflects
the consideration we expect to receive in exchange for those IP Rights. Revenue contracts that provide promises to grant the right to
use IP Rights as they exist at the point in time at which the IP Rights are granted, are accounted for as performance obligations satisfied
at a point in time and revenue is recognized at the point in time that the applicable performance obligations are satisfied and all other
revenue recognition criteria have been met.</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; color: #7030A0"><font style="color: Black">For
the periods presented, revenue contracts executed by the Company primarily provided for the payment of contractually determined, one-time,
paid-up license fees in consideration for the grant of certain IP Rights for patented technologies owned or controlled by Acacia. Revenues
also included license fees from sales-based revenue contracts, the majority of which were originally executed in prior periods, which
provide for the payment of quarterly license fees based on quarterly sales of applicable product units by licensees (&#8220;Recurring
Revenue Agreements&#8221;). Revenues may also include court ordered settlements or awards related to our patent portfolio or sales of
our patent portfolio. IP Rights granted included the following, as applicable: (i) the grant of a non-exclusive, retroactive and future
license to manufacture and/or sell products covered by patented technologies, (ii) a covenant-not-to-sue, (iii) the release of the licensee
from certain claims, and (iv) the dismissal of any pending litigation. The IP Rights granted were perpetual in nature, extending until
the legal expiration date of the related patents. The individual IP Rights are not accounted for as separate performance obligations,
as (i) the nature of the promise, within the context of the contract, is to transfer combined items to which the promised IP Rights are
inputs and (ii) the Company's promise to transfer each individual IP right described above to the customer is not separately identifiable
from other promises to transfer IP Rights in the contract.</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; color: #7030A0"><font style="color: Black">Since the promised IP Rights
are not individually distinct, the Company combined each individual IP Right in the contract into a bundle of IP Rights that is distinct,
and accounted for all of the IP Rights promised in the contract as a single performance obligation. The IP Rights granted were &#8220;functional
IP rights&#8221; that have significant standalone functionality. Acacia's subsequent activities do not substantively change that functionality
and do not significantly affect the utility of the IP to which the licensee has rights. Acacia&#8217;s operating subsidiaries have no
further obligation with respect to the grant of IP Rights, including no express or implied obligation to maintain or upgrade the technology,
or provide future support or services. The contracts provide for the grant (i.e., transfer of control) of the licenses, covenants-not-to-sue,
releases, and other significant deliverables upon execution of the contract. Licensees legally obtain control of the IP Rights upon execution
of the contract. As such, the earnings process is complete and revenue is recognized upon the execution of the contract, when collectability
is probable and all other revenue recognition criteria have been met. Revenue contracts generally provide for payment of contractual
amounts with 30-90 days of execution of the contract, or the end of the quarter in which the sale or usage occurs for Recurring Revenue
Agreements. Contractual payments made by licensees are generally non-refundable.</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; color: #7030A0"><font style="color: Black">For sales-based royalties,
the Company includes in the transaction price some or all of an amount of estimated variable consideration to the extent that it is probable
that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable
consideration is subsequently resolved. Notwithstanding, revenue is recognized for a sales-based royalty promised in exchange for a license
of IP Rights when the later of (i) the subsequent sale or usage occurs, or (ii) the performance obligation to which some or all of the
sales-based royalty has been allocated has been satisfied. Estimates are generally based on historical levels of activity, if available.</font></p>

with significant financing components (either explicit or implicit) are recognized at an amount that reflects the price that a licensee
would have paid if the licensee had paid cash for the IP Rights when they transfer to the licensee. In determining the transaction price,
the Company adjusts the promised amount of consideration for the effects of the time value of money. As a practical expedient, the Company
does not adjust the promised amount of consideration for the effects of a significant financing component if the Company expects, at
contract inception, that the period between when the entity transfers promised IP Rights to a customer and when the customer pays for
the IP Rights will be one year or less.</font></p>

is required to make certain judgments and estimates in connection with the accounting for revenue contracts with customers. Such areas
may include identifying performance obligations in the contract, estimating the timing of satisfaction of performance obligations, determining
whether a promise to grant a license is distinct from other promised goods or services, evaluating whether a license transfers to a customer
at a point in time or over time, allocating the transaction price to separate performance obligations, determining whether contracts
contain a significant financing component, and estimating revenues recognized at a point in time for sales-based royalties.</font></p>

estimated risk-free interest rate of 1.38 percent; term of 3.00 years; expected volatility of 38 percent; and expected dividend yield
of 0 percent. The risk-free interest rate was determined based on the yields available on U.S. Treasury zero-coupon issues. The expected

to be bifurcated from their host contract are valued separately from the host instrument. The binomial model determines the value of
a convertible bond instrument by valuing its two separate components (i.e., a cash only component which is subject to the selected risk-adjusted
discount rate and an equity component where settlement is subject to a risk-free rate) within a single lattice framework. The binomial
model utilizes the Tsiveriotis and Fernandes implementation in which a convertible instrument is split into two separate components:
a cash-only component which is subject to the selected risk-adjusted discount rate and an equity component which is subject only to the
risk-free rate. The model considers the (i) implied volatility of the value of our common stock, (ii) appropriate risk-free interest
rate, (iii) credit spread, (iv) dividend yield, (v) dividend accrual (and a step-up in rates), and (vi) event probabilities of the various
conversion and redemption scenarios.</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">The volatility of the Company&#8217;s common stock is estimated by
analyzing the Company&#8217;s historical volatility, implied volatility of publicly traded stock options, and the Company&#8217;s current
asset composition and financial leverage. The selected volatility, as described below, represents a haircut from the Company&#8217;s
actual realized historical volatility. A volatility haircut is a concept used to describe a commonly observed occurrence in which the
volatility implied by market prices involving options, warrants, and convertible debt is lower than historical actual realized volatility.
The assumed base case term used in the valuation model is the period remaining until November 15, 2027, the maturity date. The risk-free
interest rate is based on the yield on the U.S. Treasury with a remaining term equal to the expected term of the conversion and early
redemption options. The significant assumptions utilized in the Company&#8217;s valuation of the embedded derivative at March 31, 2021
are as follows: volatility of 30 percent, risk-free rate of 1.3 percent, discount rate of 8.8 percent, and a dividend yield of 0 percent.
The fair value measurement of the embedded derivative is sensitive to these assumptions and changes in these assumptions could result
in a materially different fair value measurement. Refer to Note 10 for additional information.</p><span></span>

for indicators of other-than-temporary impairment. This determination requires significant judgment. In making this judgment, Acacia
considers available quantitative and qualitative evidence in evaluating potential impairment of its investments. If the cost of an investment
exceeds its fair value, Acacia evaluates, among other factors, general market conditions and the duration and extent to which the fair
value is less than cost. Acacia also considers specific adverse conditions related to the financial health of and business outlook for
the investee, including industry and sector performance, changes in technology, and operational and financing cash flow factors. Once
a decline in fair value is determined to be other-than-temporary, an impairment charge is recorded in the condensed consolidated statements
of operations and a new cost basis in the investment is established.</font></p><span></span>
