Quarterly Report on Form 10-Q contains &#8220;forward-looking statements&#8221; that involve risks and uncertainties, as well as assumptions
that, if they never materialize or prove incorrect, could cause our results to differ materially from those expressed or implied by such
forward-looking statements. The statements contained in this Quarterly Report on Form 10-Q that are not purely historical are forward-looking
statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act
of 1934, as amended. Such forward-looking statements include any expectation of earnings, revenue or other financial items; any statements
of the plans, strategies and objectives of management for future operations; factors that may affect our operating results; statements
related to future performance and other matters that do not relate strictly to historical facts or statements of assumptions underlying
any of the foregoing. Forward-looking statements are often identified by the use of words such as, but not limited to, &#8220;anticipate,&#8221;
&#8220;believe,&#8221; &#8220;can,&#8221; &#8220;continue,&#8221; &#8220;could,&#8221; &#8220;estimate,&#8221; &#8220;expect,&#8221;

&#8220;target,&#8221; &#8220;would,&#8221; and similar expressions or variations intended to identify forward-looking statements. These
statements are based on the beliefs and assumptions of our management based on information currently available to management. Such forward-looking
statements are subject to risks, uncertainties and other important factors that could cause actual results and the timing of certain
events to differ materially from future results expressed or implied by such forward-looking statements. Except as required by law, we
undertake no obligation to update any forward-looking statements to reflect events or circumstances after the date of such statements.
Factors that could cause or contribute to such differences include various risks and uncertainties described below and elsewhere in this
Quarterly Report on Form 10-Q as well as in our Annual Report on Form 10-K for the year ended December 31, 2021 (filed with the SEC on
March 30, 2022). Furthermore, such forward-looking statements speak only as of the date of this report. Such risks and uncertainties
include, but are not limited to, the following:</span></p>

reviews opportunities to acquire or license additional intellectual property as well as other strategic alternatives. The Company&#8217;s
patent acquisition and development strategy is to focus on acquiring high quality patents which management believes have the potential
to generate significant licensing opportunities as the Company has achieved with respect to its Remote Power Patent and Mirror Worlds
Patent Portfolio. In addition, the Company may also enter into strategic relationships with third parties to develop, commercialize,
license or otherwise monetize their intellectual property.</span></p>

income or loss from equity method investments is recognized on a one-quarter lag. When the Company&#8217;s carrying value in an equity
method investment is reduced to zero, no further losses are recorded in the Company&#8217;s financial statements unless the Company guaranteed
obligations of the investee company or has committed additional funding. When the investee company subsequently reports income, the Company

on deferred income taxes of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation
allowance is recognized if it is more likely than not that some portion, or all, of a deferred tax asset will not be realized. As of

740-10, <i>Accounting for Uncertainty in Income Taxes</i>, defines uncertainty in income taxes and the evaluation of a tax position as
a two-step process. The first step is to determine whether it is more likely than not that a tax position will be sustained upon examination,
including the resolution of any related appeals or litigation based on the technical merits of that position. The second step is to measure
a tax position that meets the more-likely-than-not threshold to determine the amount of benefit to be recognized in the financial statements.
A tax position is measured at the largest amount of benefit that is greater than 50 percent likelihood of being realized upon ultimate
settlement. Tax positions that previously failed to meet the more-likely-than-not recognition threshold should be recognized in the first
subsequent period in which the threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not criteria
should be de-recognized in the first subsequent financial reporting period in which the threshold is no longer met. The Company had no
uncertain tax positions as of September 30, 2022.</span></p>

distributions to shareholders. For a corporation to be classified as a PHC, it must satisfy two tests: (i) that more than 50% in value
of its outstanding shares must be owned directly or indirectly by five or fewer individuals at any time during the second half of the
year (after applying constructive ownership rules to attribute stock owned by entities to their beneficial owners and among certain family

subject to the 20% tax on its UPHCI. In such event, the Company may issue a special cash dividend to its shareholders in an amount equal
to the UPHCI rather than incur the 20% tax.</span></p>

ASC 842, the Company determines if an arrangement is a lease at inception. Right-of-Use (&#8220;ROU&#8221;) assets and related lease
obligations are recognized at commencement date based on the present value of remaining lease payments over the lease term. For this
purpose, the Company considers only payments that are fixed and determinable at the time of commencement. As most of the Company's leases
do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date
in determining the present value of lease payments. The Company's determined incremental borrowing rate is a hypothetical rate based
on its understanding of what the Company's credit rating would be. The ROU asset also includes any
lease payments made prior to commencement and is recorded net of any lease incentives received and net of the deferred rent balance on
the date of implementation. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain
that it will exercise such options. As permitted under ASC 842, the Company has elected to not recognize ROU assets and related lease
obligations for leases with terms of twelve months or less.</span></p>

August 16, 2022, the Inflation Reduction Act of 2022 (the &#8220;IR Act&#8221;) was signed into federal law. The IR Act provides for,
among other things, a new U.S. federal 1% excise tax on certain repurchases of stock by publicly traded U.S. domestic corporations and
certain U.S. domestic subsidiaries of publicly traded foreign corporations occurring on or after January 1, 2023. The excise tax is imposed
on the repurchasing corporation itself, not its shareholders from which shares are repurchased. The amount of the excise tax is generally
1% of the fair market value of the shares repurchased at the time of the repurchase. However, for purposes of calculating the excise
tax, repurchasing corporations are permitted to net the fair market value of certain new stock issuances against the fair market value
of stock repurchases during the same taxable year. In addition, certain exceptions apply to the excise tax. The U.S. Department of Treasury
has been given authority to provide regulations and other guidance to carry out and prevent the abuse or avoidance of the excise tax.</span></p>

principal business is the development, licensing and protection of our intellectual property assets. We presently own ninety-six (96)
patents including: (i) our Cox Patent Portfolio relating to enabling technology for identifying media content on the Internet and taking
further action to be performed after such identification; (ii) our M2M/IoT Patent Portfolio relating to, among other things, enabling
technology for authenticating, provisioning and using embedded sim technology in next generation IoT, Machine-to-Machine, and other mobile
devices, including smartphones, tablets and computers; (iii) our HFT Patent Portfolio covering certain advanced technologies relating
to high frequency trading, which inventions specifically address technological problems associated with speed and latency and provide
critical latency gains in trading systems where the difference between success and failure may be measured in nanoseconds; (iv) our Mirror
Worlds Patent Portfolio relating to foundational technologies that enable unified search and indexing, displaying and archiving of documents
in a computer system; and (v) our Remote Power Patent covering the delivery of power over Ethernet (PoE) cables for the purpose of remotely
powering network devices, such as wireless access ports, IP phones and network based cameras.&#160;&#160;In addition, we continually
review opportunities to acquire or license additional intellectual property as well as other strategic alternatives.</span></p>

September 30, 2022, our principal sources of liquidity consisted of cash and cash equivalents and marketable securities of $48,923,000

property as well as evaluate other strategic opportunities.</span></p>

the period December 2018 through August 2022, we made an aggregate investment of $7,000,000 in ILiAD Biotechnologies, LLC (&#8220;ILiAD&#8221;),
a clinical stage biotechnology company with an exclusive license to sixty-two&#160;(62) patents (see Note J to our unaudited condensed

the three and nine months ended September 30, 2022, we recorded a gain on our investment in ILiAD of $3,727,000 due to an observable

on conversion of our convertible note from ILiAD of $271,000 as a result of the conversion of the convertible note in the private

have been dependent upon our Remote Power Patent for a significant portion of our revenue. Our Remote Power Patent generated licensing
revenue in excess of $187,000,000 from May 2007 through September 30, 2022. We no longer receive licensing revenue for our Remote Power
Patent for any period subsequent March 7, 2020 (the expiration date of the patent). We recently commenced litigations against nine defendants

current strategy includes continuing our licensing efforts with respect to our intellectual property assets and the monetization of our

of their patented technologies. We may also enter into strategic relationships with third parties to develop, commercialize, license
or otherwise monetize their intellectual property. Our patent acquisition and development strategy is to focus on acquiring high quality
patents which management believes have the potential to generate significant licensing opportunities as we have achieved with respect

had no revenue for the three and nine months ended September 30, 2022. Our revenue of $35,692,000 for the nine months ended September

from our litigation settlement with Hewlett-Packard (see Notes I[1] and I[2] to our unaudited condensed consolidated financial statements
included herein). While we have pending litigation involving certain patents within our Cox Patent Portfolio and our Remote Power Patent
and have appealed the judgment of the District Court dismissing our litigation against Facebook on the grounds of non&#45;infringement
involving certain patents within our Mirror Worlds Portfolio, we may not achieve successful outcomes of such litigation or the appeal.
Accordingly, our future revenue is uncertain.</span></p>

method investments are equity securities in entities that we do not control but over which we have the ability to exercise significant

price transactions, if any. Our proportionate share of the income or loss from equity method investments is recognized on a one-quarter
lag. When our carrying value in an equity method investment is reduced to zero, no further losses are recorded in our financial statements
unless we guaranteed obligations of the investee company or have committed additional funding. When the investee company subsequently
reports income, we will not record our share of such income until it equals the amount of our share of losses not previously</span></p>

In the event the equity method investee enters into an observable price transaction, the Company will increase or decrease the carrying
value in its equity method investment based on the fair value indicated by such transaction. Upon sale of equity method investments,
the difference between sales proceeds and the carrying amount of the equity investment is recognized in profit or loss. In determining
whether an equity method investment&#160;is impaired, we take into consideration a variety of factors including the operating and financial
performance of the investee, the investee&#8217;s future business plans and projections, discussions with the investee&#8217;s management,
and our intent and ability to hold the investment until it recovers in value. Accordingly, we make assumptions and estimates in assessing
whether an impairment has occurred and if, in the future, our assumptions and estimates made in assessing the fair value of these investments
change, this could result in a material decrease in the carrying value of the investment. This would cause us to write-down the carrying
value of the investment and could have a material adverse effect on our results of operations in the period the impairment charge is
taken.</span></p>

<p style="font: 12pt Times New Roman, Times, Serif; margin: 0 0 12pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">We
account for income taxes in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) <i>Topic
740, Income Taxes</i> (ASC 740), which requires us to use the assets and liability method of accounting for income taxes. Under the assets
and liability method, deferred income taxes are recognized for the tax consequences of temporary (timing) differences by applying enacted
statutory tax rates applicable to future years to differences between financial statement carrying amounts and the tax bases of existing
assets and liabilities and operating loss and tax credit carry forwards. Under this accounting standard, the effect on deferred income
taxes of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recognized
if it is more likely than not that some portion, or all, of a deferred tax asset will not be realized. In evaluating the need for a valuation
allowance, we estimate future taxable income based on management business plans. This process involves significant management judgment
about assumptions that are subject to change from period to period. Because the recognition of deferred tax assets requires management
to make significant judgments about future earnings, the periods in which items will impact taxable income and the application of inherently
complex tax laws, we have identified the assessment of deferred tax assets and the need for any related valuation allowance as a critical
accounting estimate.</span></p>

upfront license fees, and ongoing royalties on licensed products sold by the licensee. Generally, in the event of a litigation settlement

if any, plus or minus the Company&#8217;s share of an investee&#8217;s income or loss. The Company&#8217;s proportionate share of the
income or loss from equity method investments is recognized on a one-quarter lag. When the Company&#8217;s carrying value in an equity
method investment is reduced to zero, no further losses are recorded in the Company&#8217;s financial statements unless the Company guaranteed
obligations of the investee company or has committed additional funding. When the investee company subsequently reports income, the Company
will not record its share of such income until it equals the amount of its share of losses not previously recognized.</span></p>

by applying enacted statutory tax rates applicable to future years to differences between financial statement carrying amounts and the
tax bases of existing assets and liabilities and operating loss and tax credit carry forwards. Under this accounting standard, the effect
on deferred income taxes of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation
allowance is recognized if it is more likely than not that some portion, or all, of a deferred tax asset will not be realized. As of
September 30, 2022, the Company had total deferred tax assets generated from the Company&#8217;s activities totaling $<span id="xdx_903_eus-gaap--DeferredTaxAssetsGross_c20220930_pp0p0" title="Deferred tax assets">803,000</span>. The Company&#8217;s

740-10, <i>Accounting for Uncertainty in Income Taxes</i>, defines uncertainty in income taxes and the evaluation of a tax position as
a two-step process. The first step is to determine whether it is more likely than not that a tax position will be sustained upon examination,
including the resolution of any related appeals or litigation based on the technical merits of that position. The second step is to measure
a tax position that meets the more-likely-than-not threshold to determine the amount of benefit to be recognized in the financial statements.
A tax position is measured at the largest amount of benefit that is greater than 50 percent likelihood of being realized upon ultimate
settlement. Tax positions that previously failed to meet the more-likely-than-not recognition threshold should be recognized in the first
subsequent period in which the threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not criteria
should be de-recognized in the first subsequent financial reporting period in which the threshold is no longer met. The Company had no
uncertain tax positions as of September 30, 2022.</span></p>

purpose, the Company considers only payments that are fixed and determinable at the time of commencement. As most of the Company's leases
do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date
in determining the present value of lease payments. The Company's determined incremental borrowing rate is a hypothetical rate based
on its understanding of what the Company's credit rating would be. The ROU asset also includes any
lease payments made prior to commencement and is recorded net of any lease incentives received and net of the deferred rent balance on
the date of implementation. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain
that it will exercise such options. As permitted under ASC 842, the Company has elected to not recognize ROU assets and related lease
obligations for leases with terms of twelve months or less.</span></p>

Inc. (&#8220;Facebook&#8221;) in the U.S. District Court for the Southern District of New York, for infringement of U.S. Patent No. 6,006,227,
U.S. Patent No. 7,865,538 and U.S. Patent No. 8,255,439 (among the patents within the Company&#8217;s Mirror Worlds Patent Portfolio).
The lawsuit alleged that the asserted patents are infringed by Facebook&#8217;s core technologies that enable Facebook&#8217;s Newsfeed
and Timeline features.</span> The lawsuit further alleged that Facebook&#8217;s unauthorized use of the stream-based solutions of the Company&#8217;s
asserted patents has helped Facebook become the most popular social networking site in the world. On August 11, 2018, the Court issued
an order granting Facebook&#8217;s motion for summary judgment of non-infringement and dismissed the case. On August 17, 2018, the Company
filed a Notice of Appeal to appeal the summary judgment decision to the U.S. Court of Appeals for the Federal Circuit. On January 23,
2020, the U.S. Court of Appeals for the Federal Circuit reversed the summary judgment finding of the District Court and remanded the
litigation to the Southern District of New York for further proceedings.</span></p>

<p style="font: 12pt Times New Roman, Times, Serif; margin: 0 0 6pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">On
March 7, 2022, the District Court entered a ruling granting in part and denying in part a motion for summary judgment by Facebook. In
its ruling the Court (i) denied Facebook&#8217;s motion that the asserted patents were invalid by concluding that all asserted claims
were patent eligible under &#167;101 of the Patent Act and (ii) granted summary judgment of non-infringement in favor of Facebook
and dismissed the case. The Company strongly disagrees with the decision of the District Court on non-infringement and on April 4,
2022, the Company filed a notice of appeal to the U.S. Court of Appeals for the Federal Circuit. On April 18, 2022, Facebook filed a
notice of cross-appeal with respect to the Court&#8217;s ruling on validity. On September 19, 2022, the Company filed its brief on the
appeal.</span></p>

of New York, County of New York, for breach of a Settlement and License Agreement, dated May 22, 2009, with the Company (the &#8220;Agreement&#8221;)
for failure to make royalty payments, and provide corresponding royalty reports, to the Company based on sales of Netgear&#8217;s PoE
products. On October 22, 2021, Netgear filed a Demand for Arbitration at the American Arbitration Association (&#8220;AAA&#8221;) seeking
to arbitrate certain issues raised in the litigation. The Company objected to jurisdiction at the AAA. On April 1, 2022, the Court denied
Netgear&#8217;s motion to compel arbitration. On April 22, 2022, Netgear filed a counterclaim in the Court action alleging that the Company
breached the Agreement by not offering Netgear lower royalties. On September 22, 2022, the arbitration brought by Netgear was dismissed
by the AAA on jurisdiction grounds.</span></p>

<p style="font: 12pt Times New Roman, Times, Serif; margin: 0 0 6pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">On
August 24, 2022, ILiAD completed a private financing of $<span id="xdx_902_eus-gaap--LineOfCredit_iI_c20220824__dei--LegalEntityAxis__custom--ILiADBiotechnologiesLLCMember_zqx1Ecgeczw3" title="Private financing - D units">42,836,000</span>

This private financing represented an observable price transaction in accordance with ASC 323, and resulted in dilution in the
Company&#8217;s ownership in the investee (ILiAD). In accordance with ASC 323-10-40-1 the Company accounted for the
dilution as if it had sold a portion of its investment. As a result, the Company increased the carrying value of its ILiAD
investment by $3,727,000 and recognized an unrealized gain based on the excess of the fair value of the securities issued by ILiAD
over the carrying value of the Company&#8217;s diluted shares.

Company has accounted for the transaction in accordance with ASC 323-10-40-1, which states that an equity method investor (the
Company) shall account for a share issuance by an investee (ILiAD) as if the investor had sold a proportionate share of its
investment in the transaction and records a gain or loss associated with the dilution of its investment. The difference between the
securities of ILiAD owned by the Company and the securities sold in the Financing were not material. Accordingly, the Company valued
its securities at the observable transaction price. Any gain or loss to the investor resulting from an investee&#8217;s share
issuance shall be recognized in earnings.</span></p>

August 16, 2022, the Inflation Reduction Act of 2022 (the &#8220;IR Act&#8221;) was signed into federal law. The IR Act provides for,
among other things, a new U.S. federal 1% excise tax on certain repurchases of stock by publicly traded U.S. domestic corporations and
certain U.S. domestic subsidiaries of publicly traded foreign corporations occurring on or after January 1, 2023. The excise tax is imposed
on the repurchasing corporation itself, not its shareholders from which shares are repurchased. The amount of the excise tax is generally
1% of the fair market value of the shares repurchased at the time of the repurchase. However, for purposes of calculating the excise
tax, repurchasing corporations are permitted to net the fair market value of certain new stock issuances against the fair market value
of stock repurchases during the same taxable year. In addition, certain exceptions apply to the excise tax. The U.S. Department of Treasury
has been given authority to provide regulations and other guidance to carry out and prevent the abuse or avoidance of the excise tax.</span></p>

upfront license fees, and ongoing royalties on licensed products sold by the licensee. Generally, in the event of a litigation settlement
related to the Company&#8217;s assertion of patent infringement involving its intellectual property, defendants will either pay (i) a
non-refundable lump sum payment for a non-exclusive fully-paid license, or (ii) a non-refundable lump sum payment (license initiation
fee) together with an ongoing obligation to pay quarterly or monthly royalties to the Company for the life of the licensed patent.</span></p>

method investments are equity securities in entities the Company does not control but over which it has the ability to exercise significant
influence. These investments are accounted for under the equity method of accounting in accordance with ASC 323, <i>Investments &#8212;
Equity Method and Joint Ventures</i> (see&#160;Note&#160;J&#160;hereof). Equity method investments are measured at cost minus impairment,
if any, plus or minus the Company&#8217;s share of an investee&#8217;s income or loss. The Company&#8217;s proportionate share of the
income or loss from equity method investments is recognized on a one-quarter lag. When the Company&#8217;s carrying value in an equity
method investment is reduced to zero, no further losses are recorded in the Company&#8217;s financial statements unless the Company guaranteed
obligations of the investee company or has committed additional funding. When the investee company subsequently reports income, the Company
will not record its share of such income until it equals the amount of its share of losses not previously recognized.</span></p>

a sale of an equity method investment by the Company, the difference between sales proceeds and the carrying amount of the equity
investment is recognized in profit or loss. Upon the issuance of securities by the equity method investee in an observable price
transaction, the Company will account for the share issuance by an investee as if the Company had sold a proportionate share of its
investment in the transaction and records a gain or loss associated with the Company&#8217;s dilution of its investment with respect
to the transaction. As such the Company will increase or decrease its basis in the non-marketable equity of the investee and record a gain or
loss associated with the dilution of the investment basis based on the fair value indicated by the issuance of the securities. The
resulting gain or loss related to the dilution is recorded within other income or expense in the Company&#8217;s unaudited condensed
consolidated statements of operations and comprehensive income (loss).</span></p>

Company accounts for income taxes in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC)
<i>Topic 740, Income Taxes</i> (ASC 740), which requires the Company to use the assets and liability method of accounting for income
taxes. Under the assets and liability method, deferred income taxes are recognized for the tax consequences of temporary (timing) differences
by applying enacted statutory tax rates applicable to future years to differences between financial statement carrying amounts and the
tax bases of existing assets and liabilities and operating loss and tax credit carry forwards. Under this accounting standard, the effect
on deferred income taxes of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation
allowance is recognized if it is more likely than not that some portion, or all, of a deferred tax asset will not be realized. As of
September 30, 2022, the Company had total deferred tax assets generated from the Company&#8217;s activities totaling $<span id="xdx_903_eus-gaap--DeferredTaxAssetsGross_c20220930_pp0p0" title="Deferred tax assets">803,000</span>. The Company&#8217;s

740-10, <i>Accounting for Uncertainty in Income Taxes</i>, defines uncertainty in income taxes and the evaluation of a tax position as
a two-step process. The first step is to determine whether it is more likely than not that a tax position will be sustained upon examination,
including the resolution of any related appeals or litigation based on the technical merits of that position. The second step is to measure
a tax position that meets the more-likely-than-not threshold to determine the amount of benefit to be recognized in the financial statements.
A tax position is measured at the largest amount of benefit that is greater than 50 percent likelihood of being realized upon ultimate
settlement. Tax positions that previously failed to meet the more-likely-than-not recognition threshold should be recognized in the first
subsequent period in which the threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not criteria
should be de-recognized in the first subsequent financial reporting period in which the threshold is no longer met. The Company had no
uncertain tax positions as of September 30, 2022.</span></p>

distributions to shareholders. For a corporation to be classified as a PHC, it must satisfy two tests: (i) that more than 50% in value
of its outstanding shares must be owned directly or indirectly by five or fewer individuals at any time during the second half of the
year (after applying constructive ownership rules to attribute stock owned by entities to their beneficial owners and among certain family
members and other related parties) (the &#8220;Ownership Test&#8221;) and (ii) at least 60% of its adjusted ordinary gross income for

if it satisfies both the Ownership Test and Income Test. If the Company were to become a PHC in 2022 or any future year, it would be
subject to the 20% tax on its UPHCI. In such event, the Company may issue a special cash dividend to its shareholders in an amount equal
to the UPHCI rather than incur the 20% tax.</span></p>

ASC 842, the Company determines if an arrangement is a lease at inception. Right-of-Use (&#8220;ROU&#8221;) assets and related lease
obligations are recognized at commencement date based on the present value of remaining lease payments over the lease term. For this
purpose, the Company considers only payments that are fixed and determinable at the time of commencement. As most of the Company's leases
do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date
in determining the present value of lease payments. The Company's determined incremental borrowing rate is a hypothetical rate based
on its understanding of what the Company's credit rating would be. The ROU asset also includes any
lease payments made prior to commencement and is recorded net of any lease incentives received and net of the deferred rent balance on
the date of implementation. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain
that it will exercise such options. As permitted under ASC 842, the Company has elected to not recognize ROU assets and related lease
obligations for leases with terms of twelve months or less.</span></p>

Securities issued include securities outstanding and securities held in treasury. Temporary equity is a security with redemption features that are outside the control of the issuer, is not classified as an asset or liability in conformity with GAAP, and is not mandatorily redeemable. Includes any type of security that is redeemable at a fixed or determinable price or on a fixed or determinable date or dates, is redeemable at the option of the holder, or has conditions for redemption which are not solely within the control of the issuer. If convertible, the issuer does not control the actions or events necessary to issue the maximum number of shares that could be required to be delivered under the conversion option if the holder exercises the option to convert the stock to another class of equity. If the security is a warrant or a rights issue, the warrant or rights issue is considered to be temporary equity if the issuer cannot demonstrate that it would be able to deliver upon the exercise of the option by the holder in all cases. Includes stock with put option held by ESOP and stock redeemable by holder only in the event of a change in control of the issuer.</p></div>

media content on the Internet and taking further actions to be performed after such identification; (ii) the M2M/IoT patent portfolio
(the &#x201c;M2M/IoT Patent Portfolio&#x201d;) relating to, among other things, enabling technology for authenticating, provisioning and
using embedded sim technology in next generation IoT, Machine-to-Machine, and other mobile devices, including smartphones, tablets and
computers; (iii) the HFT patent portfolio (the &#x201c;HFT Patent Portfolio&#x201d;) covering certain advanced technologies relating to
high frequency trading, which inventions specifically address technological problems associated with speed and latency and provide critical
latency gains in trading
systems where the difference between success and failure may be measured in nanoseconds; (iv) the Mirror Worlds patent portfolio (the

Company had been dependent upon its Remote Power Patent for a significant portion of its revenue. The Company no longer receives licensing
revenue for its Remote Power Patent for any period subsequent to March 7, 2020 (the expiration date of the patent). The Company&#x2019;s
future revenue is largely dependent on its ability to monetize its other patent assets.&lt;/span&gt;&lt;/p&gt;

Company&#x2019;s current strategy includes continuing to pursue licensing opportunities for its patent portfolios. In addition, the Company
reviews opportunities to acquire or license additional intellectual property as well as other strategic alternatives. The Company&#x2019;s
patent acquisition and development strategy is to focus on acquiring high quality patents which management believes have the potential
to generate significant licensing opportunities as the Company has achieved with respect to its Remote Power Patent and Mirror Worlds
Patent Portfolio. In addition, the Company may also enter into strategic relationships with third parties to develop, commercialize,
license or otherwise monetize their intellectual property.&lt;/span&gt;&lt;/p&gt;

preparation of the unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the
date of the unaudited condensed consolidated financial statements, and the reported amounts of revenues and expenses during the reporting
periods. The significant estimates and assumptions made in the preparation of the Company&#x2019;s unaudited condensed consolidated financial
statements include legal fees and related costs, income taxes, valuation of patents, and equity method investments, including evaluation
of the Company&#x2019;s basis difference. Actual results could be materially different from those estimates, upon which the carrying values

Company relies on royalty reports received from third party licensees to record its revenue. From time to time, the Company may audit
or otherwise dispute royalties reported from licensees. Any adjusted royalty revenue as a result of such audits or dispute is recorded
by the Company in the period in which such adjustment is agreed to by the Company and the licensee or otherwise determined.&lt;/span&gt;&lt;/p&gt;

from the Company&#x2019;s patent licensing business is generated from negotiated license agreements. The timing and amount of revenue
recognized from each licensee depends upon a variety of factors, including the terms of each agreement and the nature of the obligations
of the parties. These agreements may include, but not be limited to, elements related to past infringement liabilities, non-refundable
upfront license fees, and ongoing royalties on licensed products sold by the licensee. Generally, in the event of a litigation settlement
related to the Company&#x2019;s assertion of patent infringement involving its intellectual property, defendants will either pay (i) a
non-refundable lump sum payment for a non-exclusive fully-paid license, or (ii) a non-refundable lump sum payment (license initiation
fee) together with an ongoing obligation to pay quarterly or monthly royalties to the Company for the life of the licensed patent.&lt;/span&gt;&lt;/p&gt;

method investments are equity securities in entities the Company does not control but over which it has the ability to exercise significant
influence. These investments are accounted for under the equity method of accounting in accordance with ASC 323, &lt;i&gt;Investments &#x2014;
Equity Method and Joint Ventures&lt;/i&gt; (see&#160;Note&#160;J&#160;hereof). Equity method investments are measured at cost minus impairment,
if any, plus or minus the Company&#x2019;s share of an investee&#x2019;s income or loss. The Company&#x2019;s proportionate share of the
income or loss from equity method investments is recognized on a one-quarter lag. When the Company&#x2019;s carrying value in an equity
method investment is reduced to zero, no further losses are recorded in the Company&#x2019;s financial statements unless the Company guaranteed
obligations of the investee company or has committed additional funding. When the investee company subsequently reports income, the Company
will not record its share of such income until it equals the amount of its share of losses not previously recognized.&lt;/span&gt;&lt;/p&gt;

a sale of an equity method investment by the Company, the difference between sales proceeds and the carrying amount of the equity
investment is recognized in profit or loss. Upon the issuance of securities by the equity method investee in an observable price
transaction, the Company will account for the share issuance by an investee as if the Company had sold a proportionate share of its
investment in the transaction and records a gain or loss associated with the Company&#x2019;s dilution of its investment with respect
to the transaction. As such the Company will increase or decrease its basis in the non-marketable equity of the investee and record a gain or
loss associated with the dilution of the investment basis based on the fair value indicated by the issuance of the securities. The
resulting gain or loss related to the dilution is recorded within other income or expense in the Company&#x2019;s unaudited condensed
consolidated statements of operations and comprehensive income (loss).&lt;/span&gt;&lt;/p&gt;

Company accounts for income taxes in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC)
&lt;i&gt;Topic 740, Income Taxes&lt;/i&gt; (ASC 740), which requires the Company to use the assets and liability method of accounting for income
taxes. Under the assets and liability method, deferred income taxes are recognized for the tax consequences of temporary (timing) differences
by applying enacted statutory tax rates applicable to future years to differences between financial statement carrying amounts and the
tax bases of existing assets and liabilities and operating loss and tax credit carry forwards. Under this accounting standard, the effect
on deferred income taxes of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation
allowance is recognized if it is more likely than not that some portion, or all, of a deferred tax asset will not be realized. As of
September 30, 2022, the Company had total deferred tax assets generated from the Company&#x2019;s activities totaling $&lt;span id="xdx_903_eus-gaap--DeferredTaxAssetsGross_c20220930_pp0p0" title="Deferred tax assets"&gt;803,000&lt;/span&gt;. The Company&#x2019;s
deferred tax assets were offset by a valuation allowance of $&lt;span id="xdx_907_eus-gaap--DeferredTaxAssetsValuationAllowance_c20220930_pp0p0" title="Deferred Tax Assets, Valuation Allowance"&gt;533,000&lt;/span&gt; as it was determined that it is more likely than not that certain
deferred tax assets will not be realized. The Company also had a deferred tax liability of $&lt;span id="xdx_904_eus-gaap--DeferredIncomeTaxLiabilities_c20220930_pp0p0" title="Deferred tax liability"&gt;1,246,000&lt;/span&gt;, resulting in a net deferred tax

740-10, &lt;i&gt;Accounting for Uncertainty in Income Taxes&lt;/i&gt;, defines uncertainty in income taxes and the evaluation of a tax position as
a two-step process. The first step is to determine whether it is more likely than not that a tax position will be sustained upon examination,
including the resolution of any related appeals or litigation based on the technical merits of that position. The second step is to measure
a tax position that meets the more-likely-than-not threshold to determine the amount of benefit to be recognized in the financial statements.
A tax position is measured at the largest amount of benefit that is greater than 50 percent likelihood of being realized upon ultimate
settlement. Tax positions that previously failed to meet the more-likely-than-not recognition threshold should be recognized in the first
subsequent period in which the threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not criteria
should be de-recognized in the first subsequent financial reporting period in which the threshold is no longer met. The Company had no
uncertain tax positions as of September 30, 2022.&lt;/span&gt;&lt;/p&gt;

federal, state and local income tax returns prior to 2019 are not subject to examination by any applicable tax authorities, except that

personal holding company (&#x201c;PHC&#x201d;) rules under the Internal Revenue Code impose a 20% tax on a PHC&#x2019;s undistributed personal
holding company income (&#x201c;UPHCI&#x201d;), which means, in general, taxable income subject to certain adjustments and reduced by certain
distributions to shareholders. For a corporation to be classified as a PHC, it must satisfy two tests: (i) that more than 50% in value
of its outstanding shares must be owned directly or indirectly by five or fewer individuals at any time during the second half of the
year (after applying constructive ownership rules to attribute stock owned by entities to their beneficial owners and among certain family
members and other related parties) (the &#x201c;Ownership Test&#x201d;) and (ii) at least 60% of its adjusted ordinary gross income for
a taxable year consists of dividends, interest, royalties, annuities and rents (the &#x201c;Income Test&#x201d;).&lt;/span&gt;&lt;/p&gt;

the second half of 2022 through October 2022, based on available information concerning the Company&#x2019;s shareholder ownership, the
Company did not satisfy the Ownership Test. However, the Company may subsequently be determined to be a PHC in 2022 or in future years
if it satisfies both the Ownership Test and Income Test. If the Company were to become a PHC in 2022 or any future year, it would be
subject to the 20% tax on its UPHCI. In such event, the Company may issue a special cash dividend to its shareholders in an amount equal
to the UPHCI rather than incur the 20% tax.&lt;/span&gt;&lt;/p&gt;

ASC 842, the Company determines if an arrangement is a lease at inception. Right-of-Use (&#x201c;ROU&#x201d;) assets and related lease
obligations are recognized at commencement date based on the present value of remaining lease payments over the lease term. For this
purpose, the Company considers only payments that are fixed and determinable at the time of commencement. As most of the Company's leases
do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date
in determining the present value of lease payments. The Company's determined incremental borrowing rate is a hypothetical rate based
on its understanding of what the Company's credit rating would be. The ROU asset also includes any
lease payments made prior to commencement and is recorded net of any lease incentives received and net of the deferred rent balance on
the date of implementation. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain
that it will exercise such options. As permitted under ASC 842, the Company has elected to not recognize ROU assets and related lease
obligations for leases with terms of twelve months or less.&lt;/span&gt;&lt;/p&gt;

Company relies on royalty reports received from third party licensees to record its revenue. From time to time, the Company may audit
or otherwise dispute royalties reported from licensees. Any adjusted royalty revenue as a result of such audits or dispute is recorded
by the Company in the period in which such adjustment is agreed to by the Company and the licensee or otherwise determined.&lt;/span&gt;&lt;/p&gt;

from the Company&#x2019;s patent licensing business is generated from negotiated license agreements. The timing and amount of revenue
recognized from each licensee depends upon a variety of factors, including the terms of each agreement and the nature of the obligations
of the parties. These agreements may include, but not be limited to, elements related to past infringement liabilities, non-refundable
upfront license fees, and ongoing royalties on licensed products sold by the licensee. Generally, in the event of a litigation settlement
related to the Company&#x2019;s assertion of patent infringement involving its intellectual property, defendants will either pay (i) a
non-refundable lump sum payment for a non-exclusive fully-paid license, or (ii) a non-refundable lump sum payment (license initiation
fee) together with an ongoing obligation to pay quarterly or monthly royalties to the Company for the life of the licensed patent.&lt;/span&gt;&lt;/p&gt;

method investments are equity securities in entities the Company does not control but over which it has the ability to exercise significant
influence. These investments are accounted for under the equity method of accounting in accordance with ASC 323, &lt;i&gt;Investments &#x2014;
Equity Method and Joint Ventures&lt;/i&gt; (see&#160;Note&#160;J&#160;hereof). Equity method investments are measured at cost minus impairment,
if any, plus or minus the Company&#x2019;s share of an investee&#x2019;s income or loss. The Company&#x2019;s proportionate share of the
income or loss from equity method investments is recognized on a one-quarter lag. When the Company&#x2019;s carrying value in an equity
method investment is reduced to zero, no further losses are recorded in the Company&#x2019;s financial statements unless the Company guaranteed
obligations of the investee company or has committed additional funding. When the investee company subsequently reports income, the Company
will not record its share of such income until it equals the amount of its share of losses not previously recognized.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 12pt Times New Roman, Times, Serif; margin: 0 0 6pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;Upon
a sale of an equity method investment by the Company, the difference between sales proceeds and the carrying amount of the equity
investment is recognized in profit or loss. Upon the issuance of securities by the equity method investee in an observable price
transaction, the Company will account for the share issuance by an investee as if the Company had sold a proportionate share of its
investment in the transaction and records a gain or loss associated with the Company&#x2019;s dilution of its investment with respect
to the transaction. As such the Company will increase or decrease its basis in the non-marketable equity of the investee and record a gain or
loss associated with the dilution of the investment basis based on the fair value indicated by the issuance of the securities. The
resulting gain or loss related to the dilution is recorded within other income or expense in the Company&#x2019;s unaudited condensed
consolidated statements of operations and comprehensive income (loss).&lt;/span&gt;&lt;/p&gt;

Company accounts for income taxes in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC)
&lt;i&gt;Topic 740, Income Taxes&lt;/i&gt; (ASC 740), which requires the Company to use the assets and liability method of accounting for income
taxes. Under the assets and liability method, deferred income taxes are recognized for the tax consequences of temporary (timing) differences
by applying enacted statutory tax rates applicable to future years to differences between financial statement carrying amounts and the
tax bases of existing assets and liabilities and operating loss and tax credit carry forwards. Under this accounting standard, the effect
on deferred income taxes of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation
allowance is recognized if it is more likely than not that some portion, or all, of a deferred tax asset will not be realized. As of
September 30, 2022, the Company had total deferred tax assets generated from the Company&#x2019;s activities totaling $&lt;span id="xdx_903_eus-gaap--DeferredTaxAssetsGross_c20220930_pp0p0" title="Deferred tax assets"&gt;803,000&lt;/span&gt;. The Company&#x2019;s

deferred tax assets will not be realized. The Company also had a deferred tax liability of $&lt;span id="xdx_904_eus-gaap--DeferredIncomeTaxLiabilities_c20220930_pp0p0" title="Deferred tax liability"&gt;1,246,000&lt;/span&gt;, resulting in a net deferred tax

740-10, &lt;i&gt;Accounting for Uncertainty in Income Taxes&lt;/i&gt;, defines uncertainty in income taxes and the evaluation of a tax position as
a two-step process. The first step is to determine whether it is more likely than not that a tax position will be sustained upon examination,
including the resolution of any related appeals or litigation based on the technical merits of that position. The second step is to measure
a tax position that meets the more-likely-than-not threshold to determine the amount of benefit to be recognized in the financial statements.
A tax position is measured at the largest amount of benefit that is greater than 50 percent likelihood of being realized upon ultimate
settlement. Tax positions that previously failed to meet the more-likely-than-not recognition threshold should be recognized in the first
subsequent period in which the threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not criteria
should be de-recognized in the first subsequent financial reporting period in which the threshold is no longer met. The Company had no
uncertain tax positions as of September 30, 2022.&lt;/span&gt;&lt;/p&gt;

federal, state and local income tax returns prior to 2019 are not subject to examination by any applicable tax authorities, except that

personal holding company (&#x201c;PHC&#x201d;) rules under the Internal Revenue Code impose a 20% tax on a PHC&#x2019;s undistributed personal
holding company income (&#x201c;UPHCI&#x201d;), which means, in general, taxable income subject to certain adjustments and reduced by certain
distributions to shareholders. For a corporation to be classified as a PHC, it must satisfy two tests: (i) that more than 50% in value
of its outstanding shares must be owned directly or indirectly by five or fewer individuals at any time during the second half of the
year (after applying constructive ownership rules to attribute stock owned by entities to their beneficial owners and among certain family
members and other related parties) (the &#x201c;Ownership Test&#x201d;) and (ii) at least 60% of its adjusted ordinary gross income for
a taxable year consists of dividends, interest, royalties, annuities and rents (the &#x201c;Income Test&#x201d;).&lt;/span&gt;&lt;/p&gt;

the second half of 2022 through October 2022, based on available information concerning the Company&#x2019;s shareholder ownership, the
Company did not satisfy the Ownership Test. However, the Company may subsequently be determined to be a PHC in 2022 or in future years
if it satisfies both the Ownership Test and Income Test. If the Company were to become a PHC in 2022 or any future year, it would be
subject to the 20% tax on its UPHCI. In such event, the Company may issue a special cash dividend to its shareholders in an amount equal
to the UPHCI rather than incur the 20% tax.&lt;/span&gt;&lt;/p&gt;

ASC 842, the Company determines if an arrangement is a lease at inception. Right-of-Use (&#x201c;ROU&#x201d;) assets and related lease
obligations are recognized at commencement date based on the present value of remaining lease payments over the lease term. For this
purpose, the Company considers only payments that are fixed and determinable at the time of commencement. As most of the Company's leases
do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date
in determining the present value of lease payments. The Company's determined incremental borrowing rate is a hypothetical rate based
on its understanding of what the Company's credit rating would be. The ROU asset also includes any
lease payments made prior to commencement and is recorded net of any lease incentives received and net of the deferred rent balance on
the date of implementation. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain
that it will exercise such options. As permitted under ASC 842, the Company has elected to not recognize ROU assets and related lease
obligations for leases with terms of twelve months or less.&lt;/span&gt;&lt;/p&gt;

Pursuant to the Amendment, Cisco paid $&lt;span id="xdx_90C_ecustom--AmountOfRoyaltiesAgreedToBePaidByCisco_pp0p0_c20210301__20210330__srt--ConsolidatedEntitiesAxis__custom--LicenseAgreementMember_z8dvjKFgYDJ8" title="Amount of payment by Cisco to resolve contractual dispute"&gt;18,692,000&lt;/span&gt; to the Company
to resolve a dispute relating to Cisco&#x2019;s contractual obligation to pay royalties under the Agreement to the Company for the period
beginning in the fourth quarter of 2017 through March 7, 2020 (when the Remote Power Patent expired) with respect to licensing the Remote
Power Patent.&lt;/span&gt;&lt;/p&gt;

&lt;/b&gt;On July 26, 2021, the Company agreed to settle its patent litigation against Hewlett-Packard Company and Hewlett-Packard Enterprise
Company (collectively, &#x201c;HP&#x201d;) pending in the U.S. District Court for the Eastern District of Texas, Tyler Division, for infringement
of the Company&#x2019;s Remote Power Patent. Under the terms of the settlement agreement, Hewlett-Packard Enterprise Company paid the
Company $&lt;span id="xdx_907_eus-gaap--LitigationSettlementExpense_c20210701__20210726__dei--LegalEntityAxis__custom--HewlettPackardEnterpriseCompanyMember_zUqSK3kuC9ql" title="Settlement of litigation"&gt;17,000,000&lt;/span&gt; in full settlement of the litigation and HP received a fully paid license and release to the Remote Power Patent
for its full term, which applies to sales of Power over Ethernet (&#x201c;PoE&#x201d;) products by HP and its wholly-owned subsidiary Aruba
Networks, LLC.&lt;/span&gt;&lt;/p&gt;

&lt;/b&gt;On April&#160;4, 2014 and December 3, 2014, the Company initiated litigation against Google Inc. (&#x201c;Google&#x201d;) and YouTube,
LLC (&#x201c;YouTube&#x201d;) in the U.S. District Court for the Southern District of New York for infringement of several of its patents
within its Cox Patent Portfolio acquired from Dr. Cox which relate to the identification of media content on the Internet. The lawsuit
alleges that Google and YouTube have infringed and continue to infringe certain of the Company&#x2019;s patents by making,
using, selling and offering to sell unlicensed systems and related products and services, which include YouTube&#x2019;s Content ID system.
The litigations against Google and YouTube were subject to court ordered stays which were in effect from July 2, 2015 until January&#160;2,&#160;2019
as a result of proceedings at the Patent Trial and Appeal Board (PTAB) and the appeals of PTAB Final Written Decisions to the U.S. Court
of Appeals for the Federal Circuit. Pursuant to a Joint Stipulation and Order Regarding Lifting of Stays, entered on January 2, 2019,
the parties agreed, among other things, that the stays with respect to the litigations were lifted. In January 2019, the two litigations
against Google and YouTube were consolidated. Discovery has been substantially completed and a trial date has not yet been set.&lt;/span&gt;&lt;/p&gt;

&lt;/b&gt;On May 9, 2017, Mirror Worlds Technologies, LLC, the &lt;span id="xdx_906_ecustom--LitigationPendingDescription_c20170508__20170509__srt--TitleOfIndividualAxis__custom--FacebookMember" title="Litigation pending, description"&gt;Company&#x2019;s wholly-owned subsidiary, initiated litigation against Facebook,
Inc. (&#x201c;Facebook&#x201d;) in the U.S. District Court for the Southern District of New York, for infringement of U.S. Patent No. 6,006,227,
U.S. Patent No. 7,865,538 and U.S. Patent No. 8,255,439 (among the patents within the Company&#x2019;s Mirror Worlds Patent Portfolio).
The lawsuit alleged that the asserted patents are infringed by Facebook&#x2019;s core technologies that enable Facebook&#x2019;s Newsfeed
and Timeline features.&lt;/span&gt; The lawsuit further alleged that Facebook&#x2019;s unauthorized use of the stream-based solutions of the Company&#x2019;s
asserted patents has helped Facebook become the most popular social networking site in the world. On August 11, 2018, the Court issued
an order granting Facebook&#x2019;s motion for summary judgment of non-infringement and dismissed the case. On August 17, 2018, the Company
filed a Notice of Appeal to appeal the summary judgment decision to the U.S. Court of Appeals for the Federal Circuit. On January 23,
2020, the U.S. Court of Appeals for the Federal Circuit reversed the summary judgment finding of the District Court and remanded the
litigation to the Southern District of New York for further proceedings.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 12pt Times New Roman, Times, Serif; margin: 0 0 6pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;On
March 7, 2022, the District Court entered a ruling granting in part and denying in part a motion for summary judgment by Facebook. In
its ruling the Court (i) denied Facebook&#x2019;s motion that the asserted patents were invalid by concluding that all asserted claims
were patent eligible under &#xa7;101 of the Patent Act and (ii) granted summary judgment of non-infringement in favor of Facebook
and dismissed the case. The Company strongly disagrees with the decision of the District Court on non-infringement and on April 4,
2022, the Company filed a notice of appeal to the U.S. Court of Appeals for the Federal Circuit. On April 18, 2022, Facebook filed a
notice of cross-appeal with respect to the Court&#x2019;s ruling on validity. On September 19, 2022, the Company filed its brief on the
appeal.&lt;/span&gt;&lt;/p&gt;

&lt;/b&gt;On December 15, 2020, the Company filed a lawsuit against NETGEAR, Inc. (&#x201c;Netgear&#x201d;) in the Supreme Court of the State
of New York, County of New York, for breach of a Settlement and License Agreement, dated May 22, 2009, with the Company (the &#x201c;Agreement&#x201d;)
for failure to make royalty payments, and provide corresponding royalty reports, to the Company based on sales of Netgear&#x2019;s PoE
products. On October 22, 2021, Netgear filed a Demand for Arbitration at the American Arbitration Association (&#x201c;AAA&#x201d;) seeking
to arbitrate certain issues raised in the litigation. The Company objected to jurisdiction at the AAA. On April 1, 2022, the Court denied
Netgear&#x2019;s motion to compel arbitration. On April 22, 2022, Netgear filed a counterclaim in the Court action alleging that the Company
breached the Agreement by not offering Netgear lower royalties. On September 22, 2022, the arbitration brought by Netgear was dismissed
by the AAA on jurisdiction grounds.&lt;/span&gt;&lt;/p&gt;

the period December 2018 through August 2022, the Company made an aggregate investment of $&lt;span id="xdx_90B_eus-gaap--Investments_iI_pp0p0_c20220930__us-gaap--RelatedPartyTransactionAxis__custom--IliadMember_zrVwTGQ7ibE6" title="Aggregrate investment"&gt;&lt;span id="xdx_903_ecustom--BookValueOfInvestment_iI_pp0p0_c20220930__dei--LegalEntityAxis__custom--ILiADBiotechnologiesLLCMember_zfQQp3tELaMg" title="Book value of investment"&gt;7,000,000&lt;/span&gt;&lt;/span&gt; in ILiAD Biotechnologies, LLC (&#x201c;ILiAD&#x201d;),
a privately held clinical stage biotechnology company dedicated to the prevention and treatment of human disease caused by Bordetella
pertussis. ILiAD is developing key technologies that focus on validating its proprietary intranasal vaccine, BPZE1, for the prevention
of pertussis (whooping cough). At September 30, 2022, the Company owned approximately &lt;span id="xdx_90A_eus-gaap--EquityMethodInvestmentOwnershipPercentage_iI_dp_c20220930__srt--ScheduleOfEquityMethodInvestmentEquityMethodInvesteeNameAxis__custom--IliadMember__us-gaap--DerivativeInstrumentRiskAxis__custom--ClassCUnitsMember_z0dg1ynf9UZe" title="Ownership percentage not fully diluted"&gt;6.9%&lt;/span&gt; of the outstanding units of ILiAD on a non-fully

options, warrants and convertible notes). In connection with its initial investment, the Company&#x2019;s Chairman and Chief Executive
Officer obtained a seat on ILiAD&#x2019;s Board of Managers and receives the same compensation for service on the Board of Managers as
other non-management Board members.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 12pt Times New Roman, Times, Serif; margin: 0 0 6pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;On
August 24, 2022, ILiAD completed a private financing of $&lt;span id="xdx_902_eus-gaap--LineOfCredit_iI_c20220824__dei--LegalEntityAxis__custom--ILiADBiotechnologiesLLCMember_zqx1Ecgeczw3" title="Private financing - D units"&gt;42,836,000&lt;/span&gt;
of Class D units, of which a multi-national pharmaceutical company invested $&lt;span id="xdx_907_ecustom--InvestedAmount_iI_c20220824__dei--LegalEntityAxis__custom--ILiADBiotechnologiesLLCMember_zT86jUKXyMpg" title="Invested amount - multi-national pharma"&gt;30,000,000&lt;/span&gt;
(the &#x201c;Financing&#x201d;). As part of the Financing, the Company invested an additional $&lt;span id="xdx_909_ecustom--AdditionalInvestedAmount_iI_c20220824__dei--LegalEntityAxis__custom--ILiADBiotechnologiesLLCMember_zaeGmvDcViq3" title="Additional invested amount - D units"&gt;1,000,000&lt;/span&gt;.
This private financing represented an observable price transaction in accordance with ASC 323, and resulted in dilution in the
Company&#x2019;s ownership in the investee (ILiAD). In accordance with ASC 323-10-40-1 the Company accounted for the
dilution as if it had sold a portion of its investment. As a result, the Company increased the carrying value of its ILiAD
investment by $3,727,000 and recognized an unrealized gain based on the excess of the fair value of the securities issued by ILiAD
over the carrying value of the Company&#x2019;s diluted shares. The unrealized gain of $&lt;span id="xdx_90E_eus-gaap--DebtSecuritiesUnrealizedGainLoss_c20220701__20220930_zj5r8ROzHmze" title="Unrealized gain securities"&gt;&lt;span id="xdx_90B_eus-gaap--DebtSecuritiesUnrealizedGainLoss_c20220101__20220930_zGKZp8Zj6GY2" title="Unrealized gain securities"&gt;3,727,000&lt;/span&gt;&lt;/span&gt;
as a result of the securities issuance by ILiAD in the Financing is reflected in the Company&#x2019;s unaudited condensed
consolidated statements of operations and comprehensive income (loss) for the three and nine months ended September 30,
2022.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 12pt Times New Roman, Times, Serif; margin: 0 0 6pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;The
Company has accounted for the transaction in accordance with ASC 323-10-40-1, which states that an equity method investor (the
Company) shall account for a share issuance by an investee (ILiAD) as if the investor had sold a proportionate share of its
investment in the transaction and records a gain or loss associated with the dilution of its investment. The difference between the
securities of ILiAD owned by the Company and the securities sold in the Financing were not material. Accordingly, the Company valued
its securities at the observable transaction price. Any gain or loss to the investor resulting from an investee&#x2019;s share
issuance shall be recognized in earnings.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 12pt Times New Roman, Times, Serif; margin: 0 0 6pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;In
addition, as part of the Financing, the Company converted its convertible note in the principal amount of $&lt;span id="xdx_905_eus-gaap--DebtInstrumentFaceAmount_iI_c20220930_zO8Klkj9TqJb" title="Principal amount - convertible note"&gt;1,000,000&lt;/span&gt;

in accordance with its terms, into equity of ILiAD and has accounted for this investment under the equity method of accounting. The
Company recognized an unrealized gain on conversion of $&lt;span id="xdx_902_eus-gaap--GainsLossesOnExtinguishmentOfDebt_c20220701__20220930_z8XarAR321Q9" title="Unrealized gain on conversion - convertible note"&gt;&lt;span id="xdx_907_eus-gaap--GainsLossesOnExtinguishmentOfDebt_c20220101__20220930_z9LUwz0VA2ch" title="Unrealized gain on conversion - convertible note"&gt;271,000&lt;/span&gt;&lt;/span&gt;
based on the observable price transaction which was recognized in its unaudited condensed consolidated statements of operations and
comprehensive income (loss) for the three and nine months ended September 30, 2022.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 12pt Times New Roman, Times, Serif; margin: 0 0 6pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;For
the three months ended September 30, 2022 and 2021, the Company recorded an allocated net loss from its equity method investment in ILiAD

For the nine months ended September 30, 2022 and 2021, the Company recorded an allocated net
loss from its equity method investment in ILiAD totaling $&lt;span id="xdx_90C_ecustom--EquityInvestmentNetLoss_c20220101__20220930__us-gaap--RelatedPartyTransactionAxis__custom--IliadMember_pp0p0" title="Equity investment net loss"&gt;1,073,000&lt;/span&gt; and $&lt;span id="xdx_90E_ecustom--EquityInvestmentNetLoss_c20210101__20210930__us-gaap--RelatedPartyTransactionAxis__custom--IliadMember_pp0p0" title="Equity investment net loss"&gt;632,000&lt;/span&gt;, respectively.&lt;/span&gt;&lt;/p&gt;

on the Company&#x2019;s unaudited condensed consolidated balance sheet at September 30, 2022 is due to an excess amount paid over the
book value of the investment totaling approximately $&lt;span id="xdx_90F_eus-gaap--Investments_iI_pp0p0_c20220930__us-gaap--RelatedPartyTransactionAxis__custom--IliadMember_zjoPpi6Cp1Ie" title="Aggregrate investment"&gt;7,000,000&lt;/span&gt; which is accounted for as equity method goodwill.&lt;/span&gt;&lt;/p&gt;

August 16, 2022, the Inflation Reduction Act of 2022 (the &#x201c;IR Act&#x201d;) was signed into federal law. The IR Act provides for,
among other things, a new U.S. federal 1% excise tax on certain repurchases of stock by publicly traded U.S. domestic corporations and
certain U.S. domestic subsidiaries of publicly traded foreign corporations occurring on or after January 1, 2023. The excise tax is imposed
on the repurchasing corporation itself, not its shareholders from which shares are repurchased. The amount of the excise tax is generally
1% of the fair market value of the shares repurchased at the time of the repurchase. However, for purposes of calculating the excise
tax, repurchasing corporations are permitted to net the fair market value of certain new stock issuances against the fair market value
of stock repurchases during the same taxable year. In addition, certain exceptions apply to the excise tax. The U.S. Department of Treasury
has been given authority to provide regulations and other guidance to carry out and prevent the abuse or avoidance of the excise tax.&lt;/span&gt;&lt;/p&gt;
