        statements that may constitute &#8220;forward-looking statements&#8221; within the meaning of Section 27A of the Securities Act of 1933, as amended (the &#8220;Securities Act&#8221;), and Section 21E of the Securities Exchange Act of 1934, as amended (the &#8220;Exchange Act&#8221;).
        These forward-looking statements are based upon our current expectations, estimates, assumptions, and beliefs concerning future events and conditions and may discuss, among other things, anticipated future performance (including sales and
        earnings), expected growth, future business plans and costs and the impact of potential and ongoing litigation. Any statement that is not historical in nature is a forward- looking statement and may be identified by the use of words and phrases
        such as &#8220;anticipates,&#8221; &#8220;believes,&#8221; &#8220;estimates,&#8221; &#8220;expects,&#8221; &#8220;intends,&#8221; &#8220;plans,&#8221; &#8220;predicts,&#8221; &#8220;projects,&#8221; &#8220;will be,&#8221; &#8220;will continue,&#8221; &#8220;will likely result in,&#8221; and similar expressions. These statements include our beliefs and statements regarding
        general industry and market conditions and growth rates, as well as general domestic and international economic conditions. Readers are cautioned not to place undue reliance on forward-looking statements. Forward-looking statements are necessarily
        subject to risks, uncertainties, and other factors, many of which are outside our control, which could cause actual results to differ materially from such statements and from our historical results and experience. These risks, uncertainties and
        other factors include, but are not limited to those described in Item 1A - Risk Factors of this Report and elsewhere in this Report and those described from time to time in our future reports filed with the Securities and Exchange Commission (the
        &#8220;SEC&#8221;). Readers are cautioned that it is not possible to predict or identify all the risks, uncertainties and other factors that may affect future results and that the risks described herein should not be considered a complete list. Any
        forward-looking statement speaks only as of the date on which such statement is made, and we undertake no obligation to update or revise any forward-looking statement, whether as a result of new information, future events or otherwise.</div>

              <div style="font-family: 'Times New Roman', Times, serif; font-size: 10pt;">In the VirnetX Inc. v. Apple, Inc. (Case Nos. 6:11-cv-00563-RWS, 6:12-cv-00855-RWS) (&#8220;Apple II&#8221;) litigation, the United States Court of Appeals for the Federal
                Circuit (the &#8220;Federal Circuit&#8221;) in November 2019, affirmed-in-part, and reversed-in-part the judgment issued by the United States District Court for the Eastern District of Texas (the &#8220;district court&#8221;) in the case awarding VirnetX damages
                of $595.9 million. On October 30, 2020, after a trial in the district court, a jury returned a verdict in favor of VirnetX, awarding VirnetX over $502 million in damages. On January 15, 2021, the district court denied Apple&#8217;s motion for
                judgment as a matter of law and affirmed the jury findings. This may imply that VirnetX may soon receive over $500 million in cash, however, Apple has appealed to the Federal Circuit with regards to the judgement from the district court and
                this appeal is awaiting calendaring for oral arguments. In addition, the patents in this case are being challenged in the United States Patent and Trademark Office. If those challenges are successful, the award in the case may be reduced,
                eliminated and/or delayed for a lengthy period. The continuation of this litigation is distracting to our management, expensive, and these distractions and expenses may continue.</div>

      with U.S. GAAP. In doing so, we have to make estimates and assumptions that affect our reported amounts of assets, liabilities, revenues, and expenses, as well as related disclosure of contingent assets and liabilities. In some cases, we could
      reasonably have used different accounting policies and estimates. In some cases, changes in the accounting estimates are reasonably likely to occur from period to period. Accordingly, actual results could differ materially from our estimates. To the
      extent that there are material differences between these estimates and actual results, our financial condition or results of operations will be affected. We base our estimates on past experience and other assumptions that we believe are reasonable
      under the circumstances, and we evaluate these estimates on an ongoing basis. We refer to accounting estimates of this type as critical accounting policies and estimates, which we discuss further below. We have reviewed our critical accounting
      policies and estimates with the audit committee of our Board of Directors.</div>

    contracts with customers which often span several years. We account for this revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers. A performance obligation is a promise in a contract to transfer a distinct good or service to
    the customer. A contract&#8217;s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. Our revenue arrangements may consist of multiple-element arrangements,
    with revenue for each unit of accounting recognized as the product or service is delivered to the customer.</div>

      method. The asset and liability method requires the recognition of deferred tax assets and liabilities for expected future tax consequences of temporary differences that currently exist between the tax basis and financial reporting basis of our
      assets and liabilities. We calculate current and deferred tax provisions based on estimates and assumptions that could differ from actual results reflected on the income tax returns filed during the following years. Adjustments based on filed returns
      are recorded when identified in the subsequent years. The effect on deferred taxes for a change in tax rates is recognized in income in the period that the tax rate change is enacted. In assessing our deferred tax assets, we consider whether it is
      more likely than not that all or some portion of the deferred tax assets will not be realized.</div>

      assets when, in our judgment, based upon currently available information and other factors, it is more likely than not that all or a portion of such deferred income tax assets will not be realized. The determination of the need for a valuation
      allowance is based on an on-going evaluation of current information including, among other things, historical operating results, estimates of future earnings in different taxing jurisdictions and the expected timing of the reversals of temporary
      differences. We believe the determination to record a valuation allowance to reduce a deferred income tax asset is a significant accounting estimate because it is based, among other things, on an estimate of future taxable income in the United States
      and certain other jurisdictions, which is susceptible to change and may or may not occur, and because the impact of adjusting a valuation allowance may be material. In determining when to release the valuation allowance established against our net
      deferred income tax assets, we consider all available evidence, both positive and negative. We continually assess our ability to generate sufficient taxable income during future periods in which our deferred tax assets may be realized. If and when we
      believe it is more likely than not that we will recover our deferred tax assets, we will reverse the valuation allowance as an income tax benefit in our statements of operations.</div>

<div style="text-align: justify; color: rgb(0, 0, 0); font-family: 'Times New Roman',Times,serif; font-size: 10pt;">We account for our uncertain tax positions in accordance with U.S. GAAP, which utilizes a two-step approach to evaluate tax positions.
      Step one, recognition, requires evaluation of the tax position to determine if based solely on technical merits it is more likely than not to be sustained upon examination. Step two, measurement, is addressed only if a position is more likely than
      not to be sustained. In step two, the tax benefit is measured as the largest amount of benefit, determined on a cumulative probability basis, which is more likely than not to be realized upon ultimate settlement with tax authorities. If a position
      does not meet the more likely than not threshold for recognition in step one, no benefit is recorded until the first subsequent period in which the more likely than not standard is met, the issue is resolved with the taxing authority, or the statute
      of limitations expires. Positions previously recognized are derecognized when we subsequently determine the position no longer is more likely than not to be sustained. Evaluation of tax positions, their technical merits, and measurements using
      cumulative probability are highly subjective management estimates. Actual results could differ materially from these estimates.</div>

      approximate, fair value. When we estimate fair value, we utilize market data or assumptions that we believe market participants would use in pricing the financial instrument, including assumptions about risk and inputs to the valuation technique. We
      use valuation techniques, primarily the income and market approach, which maximizes the use of observable inputs and minimize the use of unobservable inputs for recurring fair value measurements.</div>

    consistent application of and simplify U. S. GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after
    December 15, 2020. We adopted this ASU on January 1, 2021 and there was no material impact on our financial position or cash flows as a result.</div>

<div style="text-align: justify; color: rgb(0, 0, 0); font-family: 'Times New Roman',Times,serif; font-size: 10pt;">A valuation allowance is provided for deferred tax assets when, in our judgment, based upon currently available information and other
        factors, it is more likely than not that all or a portion of such deferred income tax assets will not be realized. The determination of the need for a valuation allowance is based on an on-going evaluation of current information including, among
        other things, historical operating results, estimates of future earnings in different taxing jurisdictions and the expected timing of the reversals of temporary differences. We believe the determination to record, or reduce, a valuation allowance
        associated with a deferred income tax asset is a significant accounting estimate because it is based, among other things, on an estimate of future taxable income in the United States and certain other jurisdictions, which is susceptible to change
        and may or may not occur, and because the impact of adjusting a valuation allowance may be material. In determining when to release the valuation allowance established against our net deferred income tax assets, we consider all available evidence,
        both positive and negative. We accumulated a net operating loss (&#8220;NOL&#8221;) carryforward in the state in which we were once headquartered, which will begin to expire in <span style="-sec-ix-hidden:Fact_bd581b5b582441fc94cd11a40324bd0d">2029</span>; none of the NOL carryforward is included in our deferred tax asset because we currently have no operations in the state where such accumulated.</div>

        damages and injunctive relief. The accused products include the iPhone 5, iPod Touch 5th Generation, iPad 4th Generation, iPad mini, and the latest Macintosh computers. Post-trial motions hearing was held on July 18, 2018. On August 31, 2018, the

<div style="text-align: justify; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">On September 22, 2017, we filed with the USCAFC an appeal of the invalidity findings by the PTAB in inter-partes review proceeding
            IPR2016-00693 involving our U.S. Patent No. 7,418,504, and an appeal of the invalidity findings by the PTAB in inter-partes review proceeding IPR2016-00957 involving our U.S. Patent No. 7,921,211. On September 16, 2021, USCAFC issued an order
            remanding these appeals for the limited purpose of allowing VirnetX the opportunity to request rehearing of the PTAB&#8217;s final written decisions by the Director of the USPTO. The USCAFC retained jurisdiction over the appeals in the meantime. On
            October 18, 2021, we filed our requests for Director rehearing with the USPTO. On January 7, 2022, our requests for Director rehearing were denied. On January 21, 2022, we informed the USCAFC about the denial of Director rehearing and requested
            that the court dismiss the appeal involving IPR2016-00957 as moot and vacate the PTAB&#8217;s underlying decision. On April 4, 2022, the USCAFC vacated the PTAB&#8217;s decision in IPR2016-00957 and remanded Appeal No. 17-2594 with instructions to dismiss.
            In the April 4, 2022 order, the USCAFC further set a briefing schedule, with VirnetX&#8217;s opening brief currently due June 17, 2022.</div>

        Secure Domain Names and GABRIEL Connection Technology&#8482;, are the foundation for our new VirnetX One&#8482; platform that protects communications using Zero Trust Network Access (&#8220;ZTNA&#8221;). Our technology generates secure connections on a &#8220;zero-click&#8221; or
        &#8220;single-click&#8221; basis, significantly simplifying the deployment of secure real-time communication solutions by eliminating the need for end-users to enter any encryption information. Our portfolio of intellectual property is the foundation of our
        business model. We currently own approximately 205 total patents and pending applications, including 72 U.S. patents/patent applications and 133 foreign patents/validations/pending applications. Our patent portfolio is primarily focused on securing
        real-time communications over the Internet, and related services, and is used in all our technology and products, some of which were acquired by our principal operating subsidiary&#894; VirnetX, Inc., from Leidos, Inc., or Leidos, (f/k/a Science

        infrastructure providers, communication service providers as well as to system integrators. Our GABRIEL Connection Technology&#8482; License is offered to original equipment manufacturer (&#8220;OEM&#8221;) customers who want to adopt the GABRIEL Connection
        Technology&#8482; as their solution for establishing secure connections using secure domain names within their products. We have developed GABRIEL Connection Technology&#8482; Software Development Kit (&#8220;SDK&#8221;) to assist with rapid integration of these

        establishing secure communication links, can purchase a patent license. The number of patents licensed, and therefore the cost of the patent license to the customer, will depend upon which of the patents are used in a particular product or service.
        These licenses will typically include an initial license fee, as well as an ongoing royalty.</div>

      <div style="text-align: left; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"> <br />
      </div>

      <div style="text-align: justify; font-family: 'Times New Roman',Times,serif; font-size: 10pt;">In March and April 2022, we launched War Room&#8482; and VirnetX Matrix&#8482; on our VirnetX One&#8482; platform. During this year, we expect to launch these products in
        Asia Pacific and Europe. We also intend to continue to introduce new products on our VirnetX One&#8482; platform in the future. The introduction and launch of new products is subject to significant costs, risks of slow market acceptance, and variable
        costs of customer acquisition. While, we believe our software products will be attractive to all businesses, government agencies, cloud and on-premise application service providers, and OEMs, if we are unable to overcome these risks, we may never
        generate significant revenue from the sales of these products.</div>

    </div>

    <div><br />
    </div>

    <div style="text-align: justify; font-style: italic; font-weight: bold;">We are involved and will continue to be involved in litigation defending our patent portfolio, which can be time-consuming and costly, and we cannot anticipate the results.</div>

    <div><br />
    </div>

    <div style="text-align: justify;">We spend a significant amount of our financial and management resources to pursue our current litigation. We believe that this litigation and others that we may pursue in the future could continue for years and consume
      significant financial and management resources. The counterparties to our litigation include large, well-financed companies with substantially greater resources than us. Patent litigation is risky, and the outcome is uncertain, and we cannot assure
      you that any of our current or future litigation matters will result in a favorable outcome for us. In addition, even if we obtain favorable interim rulings or verdicts, they may be inconsistent with the ultimate resolution of the dispute.
      Furthermore, any awards we receive may be subject to obligations to Leidos and fee arrangements with outside counsel. 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 develop and commercialize our products.</div>

    <div><br />
    </div>

    <div style="text-align: justify; font-style: italic; font-weight: bold;">We may not be able to capitalize on market opportunities related to our licensing strategy or our patent portfolio.</div>

    <div><br />
    </div>

    <div style="text-align: justify;">A large part of our business strategy includes licensing our patents and technology to other companies in order to reach a larger end-user base than we could reach through direct sales and marketing efforts; as such,
      our business strategy and revenues may depend on intellectual property licensing fees and royalties for the majority of our revenues. We currently derive minimal revenue from licensing activities, and royalties, and we cannot assure you that we will
      successfully capitalize on our market opportunities or that this portion of our business strategy will succeed.</div>

    <div><br />
    </div>

    <div style="text-align: justify;">Although to date we have entered into a limited number of settlement and license agreements, we may not be successful in entering into further licensing relationships, or if we are successful in entering into such
      relationships, the acquisition of them may be expensive, and they, as well as our existing settlement and our existing and pending license agreements may not generate the financial results, we expect.</div>

    <div><br />

    <div><br />
    </div>

    <div style="text-align: justify;">We believe our patents are valid, enforceable, and valuable. Notwithstanding this belief, third parties may make claims of infringement or invalidity claims with respect to our patents and such claims could give rise
      to material cost for defense or settlement or both, jeopardize or substantially delay a successful outcome of litigation we are or may become involved in, divert resources away from our other activities, limit or cease our revenues related to such
      patents, or otherwise materially and adversely affect our business. Similar challenges could also prevent us from obtaining additional patents in the future. Additionally, several of our patents are currently, and other patents may in the future be,
      subject to USPTO post-grant inter partes review proceedings (&#8220;IPR&#8221;) which may result in all, or part of these patents being invalidated, or the claims of our patents being limited. Unfavorable or adverse outcomes in our litigation or IPRs may result
      in losses, exhaustion of financial resources, reduction in our ability to enforce our intellectual property rights, or other adverse effects, which could encumber our ability to develop and commercialize our products. Even if we are successful in
      enforcing our intellectual property rights, our patents may not ultimately provide us with any competitive advantages and may be less valuable than we currently expect. These risks may be heightened in countries other than the United States where
      laws regarding patent protection are less developed and may be negatively affected by the fact that legal standards in the United States and elsewhere for protection of intellectual property rights in Internet-related businesses are uncertain and
      still evolving. In addition, there are a significant number of United States and foreign patents and patent applications in our areas of interest, and we expect that significant litigation in these areas will continue and will add uncertainty to the
      value of certain patents and other intellectual property rights in our areas of interest. If we are unable to protect our intellectual property rights or otherwise realize value from them, our business would be negatively affected.</div>

    <div style="text-align: justify; font-style: italic;"><span style="font-weight: bold;">We can provide no assurances that the licensing of our essential security patents under FRAND will be successful</span>.</div>

    <div><br />
    </div>

    <div style="text-align: justify;">At the request of the European Telecommunications Standards Institute (&#8220;ETSI&#8221;), and the Alliance for Telecommunications Industry Solutions (&#8220;ATIS&#8221;), we agreed to update our licensing declaration to ETSI and ATIS under
      their respective Intellectual Property Rights policies. This was in response to our Statement of Patent Holder identifying a group of our patents and patent applications that we believe are or may become essential to certain developing specifications
      in the 3rd Generation Partnership Project Long Term Evolution (&#8220;LTE&#8221;), Systems Architecture Evolution project. We will make available a non-exclusive patent license under FRAND (fair, reasonable and non- discriminatory terms, and conditions, with
      compensation) for the patents identified by us that are or become essential to applicants desiring to implement the Technical Specifications identified by us, as set forth in the updated licensing declaration under the ATIS and ETSI Intellectual
      Property Rights policies. Our licensing declarations under the ATIS and ETSI Intellectual Property Rights policies may limit our flexibility in determining royalties and license terms for certain of our patents. Consequently, we cannot assure you
      that the licensing of the essential security patents will be successful or that third parties will be willing to enter into licenses with us on reasonable terms or at all, which could have an adverse effect on our business and harm our competitive
      position.</div>

    <div><br />
    </div>

    <div style="text-align: justify; font-style: italic; font-weight: bold;">Because our business is conducted or expected to be conducted in an environment that is subject to rapid change, we may be subject to various developments in regulation, law, and
      consumer preferences to which we may not be able to adapt successfully.</div>

    <div><br />
    </div>

    <div style="text-align: justify;">The current regulatory environment for our products and services remains unclear. We can give no assurance that our planned product offerings will be in compliance with laws and regulations of local, state, United
      States federal or foreign authorities. Further, we can give no assurance that we will not unintentionally violate such laws or regulations or that such laws or regulations will not be modified, or that new laws or regulations will be enacted in the
      future which would cause us to be in violation of such laws or regulations. For example, Voice-Over-Internet Protocol (&#8220;VoIP&#8221;) services are not currently subject to all the same regulations that apply to traditional telephony, but it is possible that
      similar regulations may be applied to VoIP in the future and that these could result in substantial costs to us which could adversely affect the marketability of our products and planned products related to VoIP. For further example, the use of the
      Internet and private Internet Protocol (&#8220;IP&#8221;) networks for communication is largely unregulated within the United States, but may become regulated in the future; additionally, several foreign governments have enacted measures that could restrict or
      prohibit voice communications services over the Internet or private IP networks.</div>

    <div><br />
    </div>

    <div style="text-align: justify;">Our business depends on the growth of instant messaging, VoIP, mobile services, streaming video, file transfer and remote desktop and other next-generation Internet-based applications. A decline in the use of these
      applications due to complexity or cost relative to alternate traditional or newly developed communications channels, or development of alternative technologies, could cause a material decline in the number of users in these areas.</div>

    <div><br />
    </div>

    <div style="text-align: justify;">More aggressive domestic or international regulation of the Internet in general, and Internet telephony providers and services specifically may materially and adversely affect our business, financial condition,

              States enacted sweeping changes to the United States patent system under the Leahy-Smith America Invents Act, including changes that transition the United States from a &#8220;first-to-invent&#8221; system to a &#8220;first to file&#8221; system and alter the

    <div style="text-align: justify;">Intellectual property is the subject of intense scrutiny by the courts, legislatures, and executive branches of governments around the world. Various patent offices, governments or intergovernmental bodies may
      implement new legislation, regulations or rulings that impact the patent enforcement process, or the rights of patent holders and such changes could negatively affect licensing efforts and/or litigations. For example, limitations on the ability to
      bring patent enforcement claims, limitations on potential liability for patent infringement, lower evidentiary standards for invalidating patents, increases in the cost to resolve patent disputes and other similar developments could negatively affect
      our ability to assert our patent or other intellectual property rights.</div>

    <div style="text-align: justify;">It is impossible to determine the extent of the impact of any new laws, regulations or initiatives that may be proposed, or whether any of the proposals will become enacted as laws. Compliance with any new or existing
      laws or regulations could be difficult and expensive, affect the manner in which we conduct our business and negatively impact our business, prospects, financial condition, and results of operations.</div>

    <div><br />
    </div>

    <div style="text-align: justify; font-style: italic; font-weight: bold;">If we experience security breaches or incidents, we could be exposed to liability and our reputation and business could suffer.</div>

    <div><br />
    </div>

    <div style="text-align: justify;">We expect to retain certain confidential and proprietary customer information in our secure data centers and secure domain name registry, as well as personal data and other confidential and proprietary information
      relating to our business. It will be critical to our business strategy that our facilities and infrastructure remain secure and are perceived by the marketplace to be secure. Our secure domain name registry operations will also depend on our ability
      to maintain our computer and telecommunications equipment in effective working order and to reasonably protect our systems against interruption, and potentially depend on protection by other registrars in the shared registration system. The secure
      domain name servers that we will operate will be critical hardware to our registry services operations. Therefore, we expect to have to expend significant time and money to maintain or increase the security of our products, facilities, and
      infrastructure. Security technologies are constantly being tested by computer professionals, academics and &#8220;hackers.&#8221; Advances in computer capabilities and the techniques for attacking security solutions, new discoveries in the field of cryptography
      or other events or developments could result in compromises or breaches of our security measures and could make some or all our products obsolete or unmarketable. Likewise, we may need to dedicate engineering and other resources to eliminate security
      vulnerabilities and may find it necessary or appropriate to repair or replace products already sold or licensed to our customers. Despite the security measures that we and our service providers utilize, our infrastructure and that of our service
      providers may be vulnerable to physical break-ins, ransomware, computer viruses, other malicious code attacks by hackers, phishing attacks, social engineering, or similar disruptive problems. It is possible that we may have to expend additional
      financial and other resources to address such problems. The COVID-19 pandemic is increasing vulnerability to cyber-attacks, as more individuals and companies work online, which increases these risks. As a provider of Internet security software and
      technology, we may be the target of dedicated efforts by hackers and other third parties to overcome or defeat our security measures. Any physical or electronic break-in or other security breach or incident or compromise impacting our products or any
      information stored at our secure data centers and domain name registration systems, including any compromise due to human error or employee or contractor malfeasance, may jeopardize the security of information stored on our premises or in the
      computer systems and networks of our customers. In such an event, we could face significant liability and current or potential customers could be reluctant to use our services. Additionally, any such data security incident, or the perception that one
      has occurred could also result in adverse publicity, harm to our reputation and competitive position, and therefore adversely affect the market&#8217;s perception of the security of electronic commerce and communications over IP networks as well as the
      security or reliability of our services.</div>

    <div style="text-align: justify;">A security breach or other security incident could require a substantial level of financial resources to address and otherwise respond to, may be difficult to identify or address in a timely manner, and could result in
      claims, investigations, inquiries, and other proceedings or actions by private parties or governmental entities that may divert management&#8217;s attention and require the expenditure of significant time and resources, and which may cause us to incur
      substantial fines, penalties, or other liability and related legal and other costs. Any actual or perceived security breach or other security incident may also harm our reputation and make it more difficult or impossible for us to successfully market
      to others. Any of the foregoing matters could harm our operating results and financial condition.</div>

    <div><br />
    </div>

    <div style="text-align: justify; font-style: italic; font-weight: bold;">Privacy and data security concerns, and data collection and transfer restrictions and related domestic or foreign regulations may limit the use and adoption of our solutions and
      adversely affect our business.</div>

    <div><br />
    </div>

    <div style="text-align: justify;">Personal privacy, information security, and data protection are significant issues in the United States, Europe, and many other jurisdictions where we have operations or offer our products. The regulatory framework
      governing the collection, processing, storage and use of confidential and proprietary business information and personal data is rapidly evolving. The United States federal and various state and foreign governments have adopted or proposed
      requirements regarding the collection, distribution, use, security and storage of personally identifiable information and other data relating to individuals, and federal and state consumer protection laws are being applied to enforce regulations
      related to the online collection, use and dissemination of data.</div>

    <div><br />
    </div>

    <div style="text-align: justify;">Further, many foreign countries and governmental bodies, including the European Union (&#8220;EU&#8221;), where we conduct business, have laws and regulations concerning the collection and use of personal data obtained from their
      residents or by businesses operating within their jurisdiction. These laws and regulations often are more restrictive than those in the United States. Laws and regulations in these jurisdictions apply broadly to the collection, use, storage,
      disclosure, and security of data that identifies or may be used to identify or locate an individual, such as names, email addresses and, in some jurisdictions, IP addresses.</div>

    <div><br />
    </div>

    <div style="text-align: justify;">We also expect that there will continue to be new proposed laws, regulations and industry standards concerning privacy, data protection and information security in the United States, the EU, and other jurisdictions.
      For example, the European Commission adopted a General Data Protection Regulation (the &#8220;GDPR&#8221;) that became fully effective on May 25, 2018, superseding prior EU data protection legislation, imposing more stringent EU data protection requirements, and
      providing for greater penalties for noncompliance. The United Kingdom has enacted a Data Protection Act and legislation referred to as the UK GDPR that substantially implements the GDPR. We are evaluating obligations imposed on us by the GDPR and we
      may be required to incur substantial expense in order to make significant changes to our product and business operations in connection with obtaining and maintaining compliance with the GDPR and similar legislation, such as the UK GDPR and UK Data
      Protection Act, all of which may adversely affect our revenue and product sales. California has enacted legislation, the California Consumer Privacy Act (the &#8220;CCPA&#8221;) that, among other things, requires covered companies to provide disclosures to
      California consumers, and afford such consumers abilities to opt-out of certain sales of personal information. Additionally,&#160; the California Privacy Rights Act (the &#8220;CPRA&#8221;), was approved by California voters in the November 2020 election. The CPRA
      significantly modifies the CCPA, creating obligations relating to consumer data which began on January 1, 2022, with implementing regulations expected on or before July 1, 2022, and enforcement beginning July 1, 2023. Additionally, other U.S. states
      continue to propose, and in certain cases adopt, privacy-focused legislation. For example, in March 2021, Virginia enacted the Virginia Consumer Data Protection Act, which becomes effective on January 1, 2023, in June 2021, Colorado enacted the
      Colorado Privacy Act, which takes effect July 1, 2023, and in March 2022, Utah enacted the Utah Consumer Privacy Act, which takes effect December 31, 2023. We cannot yet fully determine the impact these or future laws, regulations and standards may
      have on our business, but they may require us to modify our data processing practices and policies and to incur substantial costs and expenses in an effort to comply. Privacy, data protection and information security laws and regulations are often
      subject to differing interpretations, may be inconsistent among jurisdictions, and may be alleged to be inconsistent with our current or future practices. Additionally, we may be bound by contractual requirements applicable to our collection, use,
      processing, and disclosure of various types of data, including personal data, and may be bound by, or voluntarily comply with, self-regulatory or other industry standards relating to these matters. These and other requirements could reduce demand for
      our products, increase our costs, impair our ability to grow our business, or restrict our ability to store and process data or, in some cases, impact our ability to offer our service in some locations and may subject us to liability. Any failure or
      perceived failure to comply with applicable laws, regulations, industry standards, and contractual obligations may adversely affect our business. Further, in view of new or modified federal, state, or foreign laws and regulations, industry standards,
      contractual obligations and other legal obligations, or any changes in their interpretation, we may find it necessary or desirable to fundamentally change our business activities and practices or to expend significant resources to modify our product
      and otherwise adapt to these changes. We may be unable to make such changes and modifications in a commercially reasonable manner or at all, and our ability to develop new products and features could be limited.</div>

    <div style="text-align: justify;">In addition, potential customers of our products include local, state, federal and foreign government authorities. Sales to government authorities can be extended and unpredictable. Government authorities generally
      have complex budgeting, purchasing, and regulatory processes that govern their capital spending, and their spending is likely to be adversely impacted by economic conditions, including impacts from the COVID-19 pandemic. In addition, in many

      of which could adversely affect our business, operating results, and financial condition. In addition, we could face claims for product liability, tort, or breach of warranty, including claims relating to changes to our products made by our channel
      partners. The performance of our products could have unforeseen or unknown adverse effects on the networks over which they are delivered as well as on third-party applications and services that utilize our services, which could result in legal claims
      against us, harming our business. Furthermore, we expect to provide implementation, consulting, and other technical services in connection with the implementation and ongoing maintenance of our products, which typically involves working with
      sophisticated software, computing, and communications systems. We expect that our contracts with customers will contain provisions relating to warranty disclaimers and liability limitations, which may not be upheld. Defending a lawsuit, regardless of
      its merit, is costly and may divert management&#8217;s attention and adversely affect the market&#8217;s perception of us and our products. In addition, if our business liability insurance coverage proves inadequate or future coverage is unavailable on
      acceptable terms or at all, our business, operating results, and financial condition could be adversely impacted.</div>

    <div><br />
    </div>

    <div style="text-align: justify;">Our business will depend upon, among other things, the capacity, reliability, security, and unimpeded access of the infrastructure owned by third parties that we will use to deploy our offerings. We have no control
      over the operation, quality, or maintenance of a significant portion of that infrastructure or whether those third parties will upgrade or improve their equipment. We depend on these companies to maintain the operational integrity of our connections.
      If one or more of these companies is unable or unwilling to supply or expand its levels of service to us in the future, our operations could be severely interrupted. Also, to the extent that the number of users of networks utilizing our current or
      future products suddenly increases, the technology platform and secure hosting services which will be required to accommodate a higher volume of traffic may result in slower response times or service interruptions. System interruptions or increases
      in response time could result in a loss of potential or existing users and, if sustained or repeated, could reduce the appeal of the networks to users. In addition, users depend on real-time communications; outages caused by increased traffic could
      result in delays and system failures. These types of occurrences could cause users to perceive that our solution does not function properly and could therefore adversely affect our ability to attract and retain licensees, strategic partners, and
      customers.</div>

    <div style="text-align: justify; font-style: italic; font-weight: bold;">System failure or interruption or our failure to meet increasing demands on our systems could harm our business.</div>

    <div style="text-align: justify;">The success of our license and service offerings will depend on the uninterrupted operation of various systems, secure data centers and other computer and communication networks that we establish. To the extent, the
      number of users of networks utilizing our future products suddenly increases, the technology platform and hosting services which will be required to accommodate a higher volume of traffic may result in slower response times, service interruptions or

      assigned secure domain names for a period of time. The inability of the registrar systems we establish, including our back-office billing and collections infrastructure, and telecommunications systems to meet the demands of an increasing number of

    <div style="text-align: justify; font-style: italic; font-weight: bold;">Our ability to sell our solutions will be dependent on the quality of our technical support, and our failure to deliver high-quality technical support services could have a

    <div><br />
    </div>

      that we may not be able achieve to the foregoing, our ability to sell our products would be adversely affected, and our reputation with current and potential customers could be harmed. In addition, as we expand our operations internationally, our
      technical support team will face additional challenges, including those associated with delivering support, training, and documentation in languages other than English. Our failure to deliver and maintain high-quality technical support services to

    <div style="text-align: justify; font-style: italic; font-weight: bold;">Telephone carriers have petitioned governmental agencies to enforce regulatory tariffs, which, if granted, would increase the cost of online communication, and such increase in
      cost may impede the growth of online communication and adversely affect our business.</div>

    <div><br />
    </div>

    <div style="text-align: justify;">Use of the Internet has over-burdened existing telecommunications infrastructures, and many high traffic areas have begun to experience interruptions in service. As a result, certain local telephone carriers have
      petitioned governmental agencies to enforce regulatory tariffs on IP-telephony traffic that crosses over their traditional telephone networks. If the relief sought in these petitions is granted, the costs of communicating via online could increase
      substantially, potentially adversely affecting the growth in the use of online secure communications. Any of these developments could have an adverse effect on our business.</div>

    <div style="text-align: justify;">We expect to expand our presence internationally in Japan and elsewhere through third party arrangements such as international partnerships, joint ventures and potentially establishing international subsidiaries and
      offices. Our international expansion may present challenges and risks, including those inherent in international operations, to us and may require significant attention from management. For example, the COVID-19 pandemic has and could continue to
      disrupt and slow our international expansion and partnership efforts, as our international partners&#8217; businesses could continue to be disrupted. We may not be successful in our international partnerships, expansion efforts, and we may incur
      significant operating expenses in our efforts to expand internationally.</div>

    <div style="font-style: italic; font-weight: bold;">The global COVID-19 pandemic may harm our business, financial condition, and results of operations.</div>

    <div><br />
    </div>

    <div style="text-align: justify;">In December 2019, a novel coronavirus, COVID-19 was reported in China and in March 2020, the World Health Organization declared it a pandemic. This contagious disease outbreak and related variants have continued to
      spread across the globe and impact worldwide economic activity and financial markets. In light of the uncertain and rapidly evolving situation relating to the spread of COVID-19, we continue to take precautionary measures intended to minimize the
      risk of the virus to our employees, our customers, and other third parties with whom we interact. We continue to require all employees to work remotely and have also suspended all non-essential travel worldwide for our employees. While we have a
      distributed workforce and our employees are accustomed to working remotely or working with other remote employees, our workforce is not fully remote. Our employees and consultants travel frequently to establish and maintain relationships with one
      another, our customers and prospective customers, partners, and investors. Although we continue to monitor the situation and may adjust our current policies as more information and public health guidance becomes available, temporarily suspending
      travel and restricting the ability to do business in person could negatively affect our customer success efforts, sales and marketing efforts, challenge our ability to enter into customer contracts in a timely manner, slow down our recruiting
      efforts, or create operational or other challenges, any of which could harm our business, financial condition and results of operations. Furthermore, if a natural disaster, power outage, connectivity issue, or other event occurred that impacted our
      employees&#8217; ability to work remotely, it may be difficult or, in certain cases, not possible, for us to continue our business for a substantial period of time. The increase in remote working may also result in consumer privacy, IT security and fraud
      concerns as well as increase our exposure to potential wage and hour issues. In addition, the COVID-19 pandemic may disrupt the operations of our customers, partners, suppliers, and other third-party providers for an indefinite period of time,
      including as a result of travel restrictions, adverse effects on budget planning processes, and/or business shutdowns, all of which could negatively impact our business, financial condition, and results of operations. More generally, despite
      continued actions taken by governments and businesses to attempt to contain and treat the disease, and related variants, including the distribution and administration of effective vaccines, the COVID-19 pandemic could continue to adversely affect
      economies and financial markets globally, potentially leading to an economic downturn, which could decrease technology spending and adversely affect our business.</div>

    <div><br />
    </div>

    <div style="text-align: justify;">Our dividend policy is within the discretion of our Board of Directors and will depend upon various factors, including our business, financial condition, results of operations, capital requirements, and investment
      opportunities. We therefore cannot make assurances that our Board of Directors will determine to pay regular or special dividends in the future. Accordingly, unless our Board of Directors determines to pay dividends, stockholders will be required to

    <div><br />
    </div>

    <div style="text-align: justify;">The exercise of our outstanding vested stock options, warrants, and RSUs would dilute the ownership interests of our existing stockholders. As of March 31, 2022, we had outstanding options, warrants and RSUs to
      purchase an aggregate of 6,931,592 shares of common stock representing approximately 9.7% of our total shares outstanding of which 5,105,969 were vested and therefore exercisable. To the extent outstanding stock options are exercised, additional
      shares of common stock will be issued, existing stockholders&#8217; percentage voting interests will decline and the number of shares eligible for resale in the public market will increase. Such increase may have a negative effect on the value or market
      trading price of our common stock.</div>

    <div><br />
    </div>

    <div style="text-align: justify; font-style: italic; font-weight: bold;">Because ownership of our common stock is concentrated, investors may have limited influence on stockholder decisions.</div>

    <div><br />
    </div>

    <div style="text-align: justify;">As of March 31, 2022, our executive officers and directors beneficially owned approximately 14% of our outstanding common stock. In addition, a group of stockholders that, as of December 31, 2007, held 4,766,666
      shares, or approximately 7% of our outstanding common stock, have entered into a voting agreement with us that requires them to vote all of their shares of our voting stock in favor of the director nominees approved by our Board of Directors at each
      director election going forward, and in a manner that is proportional to the votes cast by all other voting shares as to any other matters submitted to the stockholders for a vote. However, we cannot be certain how many shares of our common stock
      this group of stockholders currently owns. Because of their beneficial ownership interest, our officers and directors could significantly influence stockholder actions of which you disapprove or that are contrary to your interests. This ability to

    <div style="text-align: justify;">In addition, the provisions of Section 203 of the Delaware General Corporation Law govern us. These provisions may prohibit large stockholders, particularly those owning 15% or more of our outstanding voting stock,
      from merging or combining with us for a certain period of time.</div>

    <div><br />
    </div>

    <div style="text-align: justify;">These and other provisions in our amended and restated certificate of incorporation, our bylaws and under Delaware law could discourage potential takeover attempts, reduce the price that investors might be willing to
      pay for shares of our common stock in the future and result in the market price being lower than it would be without these provisions.</div>

    <div><br />
    </div>

    <div style="text-align: justify; font-style: italic; font-weight: bold;">Our amended and restated bylaws designate a state or federal court located within the State of Delaware as the exclusive forum for substantially all disputes between us and our
      stockholders, which could limit our stockholders&#8217; ability to choose the judicial forum for disputes with us or our directors, officers, or employees.</div>

    <div><br />
    </div>

    <div style="text-align: justify;">Our amended and restated bylaws provide that, unless we consent in writing to the selection of an alternative forum, the sole and exclusive forum for (1) any derivative action or proceeding brought on our behalf, (2)
      any action asserting a claim of breach of a fiduciary duty owed by any of our directors, stockholders, officers, or other employees to us or our stockholders, (3) any action arising pursuant to any provision of the Delaware General Corporation Law,
      or our amended and restated certificate of incorporation or amended and restated bylaws or (4) any other action asserting a claim that is governed by the internal affairs doctrine shall be the Court of Chancery of the State of Delaware (or, if the
      Court of Chancery does not have jurisdiction, another State court in Delaware or the federal district court for the District of Delaware), in all cases subject to the court having jurisdiction over indispensable parties named as defendants.</div>

    <div><br />
    </div>

    <div style="text-align: justify;">However, notwithstanding the exclusive forum provisions, our amended and restated bylaws explicitly state that they would not preclude the filing of claims brought to enforce any liability or duty created under federal
      securities laws, including the Securities Act or the Exchange Act.</div>

    <div><br />
    </div>

    <div style="text-align: justify;">Any person or entity purchasing or otherwise acquiring any interest in any of our securities shall be deemed to have notice of and consented to this provision. This exclusive-forum provision may limit a stockholder&#8217;s
      ability to bring a claim in a judicial forum of its choosing for disputes with us or our directors, officers, or other employees, which may discourage lawsuits against us and our directors, officers, and other employees. If a court were to find this
      exclusive-forum provision in our amended and restated bylaws to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving the dispute in other jurisdictions, which could harm our results of operations.</div>

    </div>

    <div style="text-align: justify; font-style: italic; font-weight: bold;">General Risk Factors</div>

    <div><br />
    </div>

    <div style="text-align: justify; font-style: italic; font-weight: bold;">We may need to raise additional capital to support our business growth, and this capital may be dilutive, may cause our stock price to drop or may not be available on acceptable
      terms, if at all.</div>

    <div><br />
    </div>

    <div style="text-align: justify;">We may need to raise additional capital, which may not be available to us when needed or may not be available on terms acceptable to us, to support our business growth or to respond to business opportunities,
      challenges, or unforeseen circumstances, including sales under our past and any future shelf registration statements. Our ability to obtain additional capital, if and when required, will depend on our business plans, investor demand, our operating
      performance, the condition of the capital markets, the terms of our current contractual obligations and other factors.</div>

    <div><br />
    </div>

    <div style="text-align: justify;">If we raise additional funds through the issuance of equity, equity-linked or debt securities, including those under our past and any future shelf registration statements, those securities may have rights, preferences,
      or privileges senior to the rights of our common stock, and our existing stockholders may experience dilution. Additionally, we are unable to predict the future success of any future offerings. Sales of a substantial number of shares of our common
      stock in the public market, or the perception that these sales or other financings might occur, could depress the market price of our common stock, and could also impair our ability to raise capital through the sale of additional equity securities.
      If we issue debt securities or incur indebtedness, we could experience increased future payment obligations and a need to comply with restrictive covenants, such as limitations on our ability to incur additional debt, limitations on our ability to
      acquire, sell or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. If we are unable to obtain additional capital or are unable to obtain additional capital on
      satisfactory terms, our ability to continue to support our business growth or to respond to business opportunities, challenges, or other circumstances could be adversely affected, and our business may be harmed.</div>

    <div><br />
    </div>

    <div style="text-align: justify; font-style: italic; font-weight: bold;">The departure of Kendall Larsen, our Chief Executive Officer and President, and/or other key personnel could compromise our ability to execute our strategic plan and materially
      harm our business.</div>

    <div><br />
    </div>

    <div style="text-align: justify;">Our success depends on the skills, experience, and performance of our key personnel. Due to the specialized nature of our business and limited staff, we are particularly dependent on Kendall Larsen, our Chief Executive
      Officer and President. We have no employment agreements with any of our key executives that prevent them from leaving us at any time. In addition, we do not maintain key person life insurance for any of our officers or key employees. The loss of Mr.
      Larsen, or our failure to retain other key personnel or plan for the succession of key personnel, would jeopardize our ability to execute our strategic plan and materially harm our business.</div>

    <div><br />
    </div>

    <div style="text-align: justify; font-style: italic; font-weight: bold;">We will need to recruit and retain additional qualified personnel to successfully grow our business.</div>

    <div><br />
    </div>

    <div style="text-align: justify;">Our future success will depend, in part, on our ability to attract and retain qualified engineering, operations, marketing, sales and executive personnel. Inability to attract and retain such personnel could adversely
      affect our business. Competition for engineering, operations, marketing, sales, and executive personnel is intense, particularly in the technology and Internet sectors and in the regions where we conduct our business. We may need to invest
      significant amounts of cash and equity to attract and retain employees and expend significant time and resources to identify, recruit, train and integrate such employees, and we may never realize returns on these investments. Additionally, we can
      provide no assurance that we will attract or retain such personnel.</div>

    <div><br />
    </div>

    <div style="text-align: justify; font-style: italic; font-weight: bold;">We have incurred and will continue to incur significant costs as a result of operating as a public company, and our management will be required to continue to devote substantial
      time to various compliance initiatives.</div>

    <div><br />
    </div>

    <div style="text-align: justify;">The Sarbanes-Oxley Act of 2002, the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, as well as other rules implemented by the SEC and the New York Stock Exchange (&#8220;NYSE&#8221;), impose various requirements
      on public companies, including requiring changes in corporate governance practices. These and proposed corporate governance laws and regulations under consideration may further increase our compliance costs. If compliance with these various legal and
      regulatory requirements diverts our management&#8217;s attention from other business concerns, it could have a material adverse effect on our business, financial condition, and operating results. The Sarbanes-Oxley Act requires, among other things, that we
      assess the effectiveness of our internal control over financial reporting annually and disclosure controls and procedures quarterly. If we are unable to assert in any future reporting periods that our internal control over financial reporting is
      effective (or if our independent registered public accounting firm is unable to express an opinion on the effectiveness of our internal controls), we could lose investor confidence in the accuracy and completeness of our financial reports, which
      would have an adverse effect on our share price.</div>

    <div style="text-align: justify;"> <br />
    </div>

    <div style="clear: both; margin-top: 10pt; margin-bottom: 10pt;" class="DSPFPageBreakArea">
      <div style="text-align: center;" class="DSPFPageNumberArea"><span style="font-family: 'Times New Roman', Times, serif; font-size: 8pt; font-weight: normal; font-style: normal;" class="DSPFPageNumber">34</span></div>

      <div style="page-break-after:always;" class="DSPFPageBreak">
        <hr style="margin: 4px 0px; width: 100%; border-width: 0; height: 2px; color: #000000; background-color: #000000; clear: both;" /></div>

      </div>

    </div>

    <div style="text-align: justify;">Although we believe that we currently maintain effective control over our disclosures and procedures and internal control over financial reporting, we may in the future identify deficiencies regarding the design and
      effectiveness of our system of internal control over financial reporting. If we experience any material weaknesses in our internal control over financial reporting in the future or are unable to provide unqualified management or attestation reports
      about our internal controls, we may be unable to meet financial and other reporting deadlines and may incur costs associated with remediation, and any of which could cause our share price to decline. Moreover, if we identify deficiencies in our
      internal control over financial reporting that are deemed to be material weaknesses in future periods, the market price of our common stock could decline, and we could be subject to potential delisting by the NYSE and review by the NYSE, the SEC, or
      other regulatory authorities, which would require the expenditure by us of additional financial and management resources. As a result, our shareholders could lose confidence in our financial reporting, which would harm our business and the market
      price of our common stock.</div>

    <div><br />
    </div>

    <div style="text-align: justify; font-style: italic; font-weight: bold;">There are inherent uncertainties involved in estimates, judgments and assumptions used in the preparation of financial statements in accordance with U.S. GAAP. Any changes in
      estimates, judgments and assumptions could have a material adverse effect on our business, financial condition, and operating results.</div>

    <div><br />
    </div>

    <div style="text-align: justify;">The preparation of financial statements in accordance with U.S. GAAP involves making estimates, judgments and assumptions that affect reported amounts of assets (including intangible assets), liabilities and related
      reserves, revenues, expenses, and income. Estimates, judgments, and assumptions are inherently subject to change in the future, and any such changes could result in corresponding changes to the amounts of assets, liabilities, revenues, expenses, and
      income. Any such changes could have a material adverse effect on our business, financial condition, and operating results.</div>

    <div><br />
    </div>

    <div style="text-align: justify; font-style: italic; font-weight: bold;">Our results of operations and financial condition could be materially affected by the enactment of legislation implementing changes in the U.S. or foreign taxation of
      international business activities or the adoption of other tax reform policies.</div>

    <div><br />
    </div>

    <div style="text-align: justify;">As we expand the scale of our international business activities, any changes in the U.S. or foreign taxation of such activities may increase our worldwide effective tax rate and harm our business, results of
      operations, and financial condition. For example, the current administration has proposed to increase the U.S. corporate income tax rate, increase U.S. taxation of international business operations, and impose a global minimum tax which has agreement
      from, many countries and the Organisation for Economic Cooperation and Development. Also, starting in fiscal year 2022, the Tax Cuts and Jobs Act requires taxpayers to capitalize research and development expenditures and to amortize domestic
      expenditures over five years and foreign expenditures over fifteen years. If Congress does not modify or repeal this provision, it may reduce our cash flows beginning in fiscal year 2022.&#160; Other countries have recently proposed or recommended changes
      to existing tax laws or have enacted new laws that could impact our tax obligations in countries where we do business or cause us to change the way we operate our business. The impact of future changes to U.S. and foreign tax law on our business is
      uncertain and could be adverse, and we will continue to monitor and assess the impact of any such changes on our future tax provisions<span style="font-style: italic;">.</span></div>

    <div><br />
    </div>

    <div style="text-align: justify; font-style: italic; font-weight: bold;">War, terrorism, other acts of violence, or natural or manmade disasters may affect the markets in which we operate, our clients and our service delivery.</div>

    <div><br />
    </div>

    <div style="text-align: justify;">Our business may be adversely affected by instability, disruption, or destruction in a geographic region in which we operate, regardless of cause, including war, terrorism, riot, civil insurrection, or social unrest,
      and natural or manmade disasters, including famine, flood, fire, earthquake, storm, or pandemic events and spread of disease, such as the COVID-19 pandemic and the Russian invasion of Ukraine. Such events may cause our customers to delay their
      decisions on spending for the services we provide and give rise to sudden significant changes in regional and global economic conditions and cycles. These events may also pose risks to our personnel and to physical facilities and operations, which
      could adversely affect our financial results.</div>

    <div style="text-align: justify;">Our common stock is currently listed on the NYSE and was previously listed on the NYSE American LLC (formerly the NYSE MKT LLC). Over the past years, the market price of our common stock has experienced significant
      fluctuations. Between April 1, 2021, and March 31, 2022, the reported last adjusted closing price on the NYSE American LLC, and now NYSE, for our common stock ranged between $1.63 and $5.59 per share. The price of our common stock may continue to be
      volatile as a result of several factors, some of which are beyond our control. These factors include, but not limited to, the following:</div>

      be beyond the full control of the SEC and Financial Institutions Regulatory Authority or &#8220;FINRA.&#8221; While the SEC and FINRA rules prohibit some forms of short selling and other activities that may result in stock price manipulation, such activity may
      nonetheless occur without detection or enforcement. We have held conversations with regulators concerning trading activity in our stock; however, there can be no assurance that should there be any illegal manipulation in the trading of our stock, it
      will be detected, prosecuted, or successfully eradicated. Significant short selling market manipulation could cause our stock trading price to decline, to become more volatile, or both.</div>

      often have been unrelated or disproportionate to the operating performance of those companies. In addition, the stock prices of many technology companies have experienced wide fluctuations that have often been unrelated to the operating performance
      of those companies. These broad market and industry fluctuations, as well as general economic, political and market conditions such as recessions, government shutdowns, global pandemics (such as the COVID-19 pandemic), interest rate changes the
      stability of the EU (including, but not limited to, effects from the exit of the United Kingdom or international currency fluctuations, may cause the market price of our common stock to decline. In the past, following periods of volatility in the

      with U.S. GAAP. In doing so, we have to make estimates and assumptions that affect our reported amounts of assets, liabilities, revenues, and expenses, as well as related disclosure of contingent assets and liabilities. In some cases, we could
      reasonably have used different accounting policies and estimates. In some cases, changes in the accounting estimates are reasonably likely to occur from period to period. Accordingly, actual results could differ materially from our estimates. To the
      extent that there are material differences between these estimates and actual results, our financial condition or results of operations will be affected. We base our estimates on past experience and other assumptions that we believe are reasonable
      under the circumstances, and we evaluate these estimates on an ongoing basis. We refer to accounting estimates of this type as critical accounting policies and estimates, which we discuss further below. We have reviewed our critical accounting
      policies and estimates with the audit committee of our Board of Directors.</div>

    contracts with customers which often span several years. We account for this revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers. A performance obligation is a promise in a contract to transfer a distinct good or service to
    the customer. A contract&#8217;s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. Our revenue arrangements may consist of multiple-element arrangements,
    with revenue for each unit of accounting recognized as the product or service is delivered to the customer.</div>

    property rights, including seeking appropriate compensation from third parties that utilize the Company&#8217;s intellectual property without a license. As a result, the Company may, from time to time, receive payments as part of a settlement or compensation
    for a patent infringement dispute. Proceeds received are allocated to each element identified in the settlement or compensation, based on the fair value of each element. Generally, settlements and compensation may include the following elements: the
    value of a license or royalty agreement, cost reimbursement, damages, and interest. Elements identified related to licensing and royalty are recognized as revenue. Elements identified as reimbursed costs are generally recorded as a reduction to the
    reported expenses. Elements identified as damages or interest are generally recorded in other income in the condensed consolidated statement of operations.</div>

      method. The asset and liability method requires the recognition of deferred tax assets and liabilities for expected future tax consequences of temporary differences that currently exist between the tax basis and financial reporting basis of our
      assets and liabilities. We calculate current and deferred tax provisions based on estimates and assumptions that could differ from actual results reflected on the income tax returns filed during the following years. Adjustments based on filed returns
      are recorded when identified in the subsequent years. The effect on deferred taxes for a change in tax rates is recognized in income in the period that the tax rate change is enacted. In assessing our deferred tax assets, we consider whether it is
      more likely than not that all or some portion of the deferred tax assets will not be realized.</div>

<div style="text-align: justify; font-family: 'Times New Roman'; font-size: 10pt; font-weight: normal; color: rgb(0, 0, 0); font-style: normal; font-variant: normal; text-transform: none;">A valuation allowance is provided for deferred income tax
      assets when, in our judgment, based upon currently available information and other factors, it is more likely than not that all or a portion of such deferred income tax assets will not be realized. The determination of the need for a valuation
      allowance is based on an on-going evaluation of current information including, among other things, historical operating results, estimates of future earnings in different taxing jurisdictions and the expected timing of the reversals of temporary
      differences. We believe the determination to record a valuation allowance to reduce a deferred income tax asset is a significant accounting estimate because it is based, among other things, on an estimate of future taxable income in the United States
      and certain other jurisdictions, which is susceptible to change and may or may not occur, and because the impact of adjusting a valuation allowance may be material. In determining when to release the valuation allowance established against our net
      deferred income tax assets, we consider all available evidence, both positive and negative. We continually assess our ability to generate sufficient taxable income during future periods in which our deferred tax assets may be realized. If and when we
      believe it is more likely than not that we will recover our deferred tax assets, we will reverse the valuation allowance as an income tax benefit in our statements of operations.</div>

<div style="text-align: justify; color: rgb(0, 0, 0); font-family: 'Times New Roman',Times,serif; font-size: 10pt;">We account for our uncertain tax positions in accordance with U.S. GAAP, which utilizes a two-step approach to evaluate tax positions.
      Step one, recognition, requires evaluation of the tax position to determine if based solely on technical merits it is more likely than not to be sustained upon examination. Step two, measurement, is addressed only if a position is more likely than
      not to be sustained. In step two, the tax benefit is measured as the largest amount of benefit, determined on a cumulative probability basis, which is more likely than not to be realized upon ultimate settlement with tax authorities. If a position
      does not meet the more likely than not threshold for recognition in step one, no benefit is recorded until the first subsequent period in which the more likely than not standard is met, the issue is resolved with the taxing authority, or the statute
      of limitations expires. Positions previously recognized are derecognized when we subsequently determine the position no longer is more likely than not to be sustained. Evaluation of tax positions, their technical merits, and measurements using
      cumulative probability are highly subjective management estimates. Actual results could differ materially from these estimates.</div>

        compensation costs on a straight-line basis over the requisite service period of the award, which is generally a vesting term of 4
        years. We recognize forfeitures, if any, when they occur. In addition, we record stock-based compensation expense for awards granted to non-employees at fair value of the consideration received or the fair value of the equity instruments issued, as
        they vest, over the performance period (See Note 5 - Stock-Based Compensation).</div>

      transaction between market participants at the measurement date. A fair value hierarchy prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or
      liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). Level 2 measurements utilize either directly or indirectly observable inputs in markets other than quoted prices in active markets.</div>

    (&#8220;FASB&#8221;) issued Accounting Standards Update (&#8220;ASU&#8221;) 2019-12 Income Taxes (Topic 740). The amendments in this ASU simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve
    consistent application of and simplify U. S. GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after
    December 15, 2020. We adopted this ASU on January 1, 2021 and there was no material impact on our financial position or cash flows as a result.</div>

<div style="text-align: justify; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">For the three months ended March 31, 2022, we recognized income tax benefit of $1,059 on loss before taxes of $4,379, which is an effective tax
        rate of 24.45%. The effective tax rate was higher than the statutory federal income tax rate primarily due to the effect of research and
        development tax credits. For the three months ended March 31, 2021, income tax benefit was $7,193 on loss before income taxes of $33,636 and an effective tax rate of 21.38%.
        The effective tax rate was higher than the statutory federal income tax rate primarily due to the effect of research and development tax credits.</div>

<div style="text-align: justify; color: rgb(0, 0, 0); font-family: 'Times New Roman',Times,serif; font-size: 10pt;">During the three months ended March 31, 2022, our deferred tax asset increased by $1,059 to $17,009. </div>

      </div>

<div style="text-align: justify; color: rgb(0, 0, 0); font-family: 'Times New Roman',Times,serif; font-size: 10pt;">A valuation allowance is provided for deferred tax assets when, in our judgment, based upon currently available information and other
        factors, it is more likely than not that all or a portion of such deferred income tax assets will not be realized. The determination of the need for a valuation allowance is based on an on-going evaluation of current information including, among
        other things, historical operating results, estimates of future earnings in different taxing jurisdictions and the expected timing of the reversals of temporary differences. We believe the determination to record, or reduce, a valuation allowance
        associated with a deferred income tax asset is a significant accounting estimate because it is based, among other things, on an estimate of future taxable income in the United States and certain other jurisdictions, which is susceptible to change
        and may or may not occur, and because the impact of adjusting a valuation allowance may be material. In determining when to release the valuation allowance established against our net deferred income tax assets, we consider all available evidence,
        both positive and negative. We accumulated a net operating loss (&#8220;NOL&#8221;) carryforward in the state in which we were once headquartered, which will begin to expire in <span style="-sec-ix-hidden:Fact_bd581b5b582441fc94cd11a40324bd0d">2029</span>; none of the NOL carryforward is included in our deferred tax asset because we currently have no operations in the state where such accumulated.</div>

<div style="font-family: 'Times New Roman'; font-size: 10pt; font-style: normal; text-align: justify;">Our tax years for 2005 and forward are subject to examination by the U.S. tax authority and various state tax authorities. These years are open due
        to NOLs, and tax credits generated in these years were utilized in 2020. The statute of limitation for these years shall expire three years after the date of filing 2020 income tax returns. </div>

<div><span style="background-color: rgb(255, 255, 255); font-weight: normal; color: rgb(0, 0, 0); font-family: 'Times New Roman'; font-size: 10pt; font-style: normal; font-variant: normal; text-transform: none;"><br/>

        recognize the financial statement effects of a tax position when it is more likely than not, based on the technical merits, that the position will be sustained upon examination. At December 31, 2021 and March 31, 2022, we have no uncertain tax positions. Our policy is to recognize interest and penalties accrued on uncertain tax positions as a component of income tax
        expense. We had no accrued interest or penalties related to uncertain tax positions at March 31, 2022.  </div>

      plan for employees and others called the VirnetX Holding Corporation 2013 Equity Incentive Plan (the &#8220;2013 Plan&#8221;), which has been approved by our stockholders. To the extent that any award should expire, become un-exercisable or is otherwise
      forfeited, the shares subject to such award will again become available for issuance under the 2013 Plan. The 2013 Plan provides for the granting of stock options and restricted stock units purchase rights (&#8220;RSUs&#8221;) to our employees and consultants.
      Stock options granted under the 2013 Plan may be incentive stock options or nonqualified stock options. Incentive stock options (&#8220;ISOs&#8221;) may only be granted to our employees (including officers and directors). Nonqualified stock options (&#8220;NSOs&#8221;) and
      stock purchase rights may be granted to our employees and consultants. The 2013 Plan expires in 2023.</div>

        under the 2013 Plan with an exercise price determined by our Board of Directors, or a duly appointed committee thereof, provided, however, that the exercise price of an option granted to any employee shall be not less than 100% of the fair market value at the date of grant in the case of ISOs or 85% of the fair market value at the date of grant in the case of an NSO. The exercise price of an ISO or NSO granted to one of our Named Executive Officers shall not be less
        than 100% of the fair market value of the shares at the date of grant and the exercise price of an ISO granted to a 10% shareholder
        shall not be less than 110% of the fair market value of the shares on the date of grant. Stock options granted under the 2013 Plan
        typically vest over four years and have a 10-year
        term. All RSUs are considered to be granted at the fair value of our stock on the date of grant because they have no exercise price. RSUs typically vest over four years. As of March 31, 2022, there were 2,240,296 shares available for grant under the 2013 Plan.</div>

        November 6, 2012, when we had filed a complaint against Apple in United States District Court (&#8220;USDC&#8221;) in which we alleged that Apple infringed on certain of our patents, (U.S. Patent Nos. 6,502,135, 7,418,504, 7,921,211 and 7,490,151). We sought
        damages and injunctive relief. The accused products include the iPhone 5, iPod Touch 5th Generation, iPad 4th Generation, iPad mini, and the latest Macintosh computers. Post-trial motions hearing was held on July 18, 2018. On August 31, 2018, the
        USDC entered a Final Judgment and issued its Memorandum Opinion and Order regarding post-trial motions, affirming the jury&#8217;s verdict of $502,600
        and granting VirnetX motions for supplemental damages, a sunset royalty, and the royalty rate of $1.20 per infringing iPhone, iPad and
        Mac products, pre-judgment and post-judgment interest and costs. Apple filed a notice of appeal with the USCAFC in the Apple II case.</div>

        USCAFC docketed the appeal as Case No. 19-1050 - VirnetX Inc. v. Apple Inc. On January 24, 2019 Apple filed its opening brief. We filed our response brief on March 1, 2019. Apple filed its reply brief on April 5, 2019. The oral arguments were heard
        on October 4, 2019. On November 22, 2019, the USCAFC issued an opinion affirming the district court&#8217;s findings that Apple is precluded from making certain invalidity arguments and that Apple infringed the &#8216;135 and &#8216;151 patents; reversing the USDC&#8217;s
        finding that Apple infringed the &#8216;504 and &#8216;211 patents; and remanding the case for proceedings on damages. Apple sought panel and en banc rehearing, which the USCAFC denied on February 10, 2020.</div>

        the USDC issued a scheduling order for the parties to brief the court about the need for a new trial for recalculating the damages. We filed our motion for entry of judgment on February 28, 2020. The arguments on this matter were heard on April 14,
        2020. In its order, unsealed on May 1, 2020, the USDC denied VirnetX&#8217;s motion for entry of a new judgment based on the prior jury verdict and ordered a new jury trial on damages. On August 10, 2020, the USDC granted Apple&#8217;s motion for continuance
        and reset the date to October 26, 2020. On October 30, 2020, a jury returned a $502,800 verdict in favor of VirnetX based on Apple&#8217;s
        infringement of two network security patents: VirnetX US Patents No. 6,502,135 and No. 7,490,151. The jury verdict called for damages of
        $0.84 per accused device since the 2013 launch of Apple&#8217;s iOS 7 operating system and represents 598,629,580 infringing units from US sales only. On January 15, 2021, the district court denied Apple&#8217;s motion for judgment as a matter of law, and on February 4, 2021, Apple
        filed a notice of appeal to the USCAFC. <br/>

          IPR2016-00062 involving our U.S. Patent No. 6,502,135, and an appeal of the invalidity findings by the PTAB in inter-partes review proceedings IPR2015-1047, IPR2016- 00063, and IPR2016-00167 involving our U.S. Patent No. 7,490,151. On September
          25, 2020, the USCAFC issued an order consolidating the two appeals. On December 15, 2020, we filed a motion to vacate the PTAB
          decisions below and to remand these appeals to the PTAB. On March 16, 2021, the USCAFC denied the motion without prejudice to us raising the challenges made in the motion in our opening brief. Our opening brief was filed on June 7, 2021.</span></div>

<div style="text-align: justify; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">On June 23, 2021, the USCAFC entered an order directing us (and parties in other appeals that raised Appointments Clause challenges) to
          file a brief explaining how they believe their cases should proceed in light of the Supreme Court&#8217;s decision in&#160;United States v. Arthrex, Inc., 141 S. Ct. 1970 (2021). On July 7, 2021, we filed a brief in response to the court&#8217;s order. Other
          parties, including the U.S. Patent and Trademark Office (&#8220;USPTO&#8221;) filed their responses on July 21, 2021. On August 19, 2021, USCAFC issued an order remanding these appeals for the limited purpose of allowing VirnetX the opportunity to request
          rehearing of the PTAB&#8217;s final written decisions by the Director of the USPTO. The USCAFC retained jurisdiction over the appeals in the meantime. On September 20, 2021, we filed our requests for Director rehearing with the USPTO. On October 29,
          2021, our requests for Director rehearing were denied. We subsequently filed an amended opening brief to the USCAFC on December 10, 2021, the other parties filed response briefs on February 2, 2022, and we filed a reply brief on February 22,

        law firm of McKool Smith, P.C. (&#8220;McKool&#8221;) filed a Demand for Arbitration against VirnetX, Inc. with the American Arbitration Association (&#8220;AAA&#8221;). In its demand, McKool claimed that a retention agreement it entered into in 2010 with VirnetX entitled
        it to a contingency fee arising from the recent 2020 payment made in the Apple I case. McKool claimed it was owed approximately $36,300
        (or 8% of the Apple I payment). We filed a general response with the AAA denying McKool&#8217;s claim and contested the matter vigorously. An
        evidentiary hearing was held on the matter during the week of February 22, 2021 and the parties submitted additional briefings. On April 19, 2021, the arbitrator awarded McKool $36,323 in damages, plus pre-judgment interest in the amount of 5% simple

        expensive and time-consuming, and there is no assurance that we could prevail on such potential claims if we made them. In addition, bringing a lawsuit may lead to potential counterclaims which may distract our management and our other resources,

      with U.S. GAAP. In doing so, we have to make estimates and assumptions that affect our reported amounts of assets, liabilities, revenues, and expenses, as well as related disclosure of contingent assets and liabilities. In some cases, we could
      reasonably have used different accounting policies and estimates. In some cases, changes in the accounting estimates are reasonably likely to occur from period to period. Accordingly, actual results could differ materially from our estimates. To the
      extent that there are material differences between these estimates and actual results, our financial condition or results of operations will be affected. We base our estimates on past experience and other assumptions that we believe are reasonable
      under the circumstances, and we evaluate these estimates on an ongoing basis. We refer to accounting estimates of this type as critical accounting policies and estimates, which we discuss further below. We have reviewed our critical accounting
      policies and estimates with the audit committee of our Board of Directors.</div>

    value of a license or royalty agreement, cost reimbursement, damages, and interest. Elements identified related to licensing and royalty are recognized as revenue. Elements identified as reimbursed costs are generally recorded as a reduction to the
    reported expenses. Elements identified as damages or interest are generally recorded in other income in the condensed consolidated statement of operations.</div>

      method. The asset and liability method requires the recognition of deferred tax assets and liabilities for expected future tax consequences of temporary differences that currently exist between the tax basis and financial reporting basis of our
      assets and liabilities. We calculate current and deferred tax provisions based on estimates and assumptions that could differ from actual results reflected on the income tax returns filed during the following years. Adjustments based on filed returns
      are recorded when identified in the subsequent years. The effect on deferred taxes for a change in tax rates is recognized in income in the period that the tax rate change is enacted. In assessing our deferred tax assets, we consider whether it is
      more likely than not that all or some portion of the deferred tax assets will not be realized.</div>

      assets when, in our judgment, based upon currently available information and other factors, it is more likely than not that all or a portion of such deferred income tax assets will not be realized. The determination of the need for a valuation
      allowance is based on an on-going evaluation of current information including, among other things, historical operating results, estimates of future earnings in different taxing jurisdictions and the expected timing of the reversals of temporary
      differences. We believe the determination to record a valuation allowance to reduce a deferred income tax asset is a significant accounting estimate because it is based, among other things, on an estimate of future taxable income in the United States
      and certain other jurisdictions, which is susceptible to change and may or may not occur, and because the impact of adjusting a valuation allowance may be material. In determining when to release the valuation allowance established against our net
      deferred income tax assets, we consider all available evidence, both positive and negative. We continually assess our ability to generate sufficient taxable income during future periods in which our deferred tax assets may be realized. If and when we
      believe it is more likely than not that we will recover our deferred tax assets, we will reverse the valuation allowance as an income tax benefit in our statements of operations.</div>

<div style="text-align: justify; color: rgb(0, 0, 0); font-family: 'Times New Roman',Times,serif; font-size: 10pt;">We account for our uncertain tax positions in accordance with U.S. GAAP, which utilizes a two-step approach to evaluate tax positions.
      Step one, recognition, requires evaluation of the tax position to determine if based solely on technical merits it is more likely than not to be sustained upon examination. Step two, measurement, is addressed only if a position is more likely than
      not to be sustained. In step two, the tax benefit is measured as the largest amount of benefit, determined on a cumulative probability basis, which is more likely than not to be realized upon ultimate settlement with tax authorities. If a position
      does not meet the more likely than not threshold for recognition in step one, no benefit is recorded until the first subsequent period in which the more likely than not standard is met, the issue is resolved with the taxing authority, or the statute
      of limitations expires. Positions previously recognized are derecognized when we subsequently determine the position no longer is more likely than not to be sustained. Evaluation of tax positions, their technical merits, and measurements using
      cumulative probability are highly subjective management estimates. Actual results could differ materially from these estimates.</div>

    consistent application of and simplify U. S. GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after
    December 15, 2020. We adopted this ASU on January 1, 2021 and there was no material impact on our financial position or cash flows as a result.</div>

Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months.

      with U.S. GAAP. In doing so, we have to make estimates and assumptions that affect our reported amounts of assets, liabilities, revenues, and expenses, as well as related disclosure of contingent assets and liabilities. In some cases, we could
      reasonably have used different accounting policies and estimates. In some cases, changes in the accounting estimates are reasonably likely to occur from period to period. Accordingly, actual results could differ materially from our estimates. To the
      extent that there are material differences between these estimates and actual results, our financial condition or results of operations will be affected. We base our estimates on past experience and other assumptions that we believe are reasonable
      under the circumstances, and we evaluate these estimates on an ongoing basis. We refer to accounting estimates of this type as critical accounting policies and estimates, which we discuss further below. We have reviewed our critical accounting
      policies and estimates with the audit committee of our Board of Directors.&lt;/div&gt;

    the customer. A contract&#x2019;s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. Our revenue arrangements may consist of multiple-element arrangements,
    with revenue for each unit of accounting recognized as the product or service is delivered to the customer.&lt;/div&gt;

    property rights, including seeking appropriate compensation from third parties that utilize the Company&#x2019;s intellectual property without a license. As a result, the Company may, from time to time, receive payments as part of a settlement or compensation
    for a patent infringement dispute. Proceeds received are allocated to each element identified in the settlement or compensation, based on the fair value of each element. Generally, settlements and compensation may include the following elements: the
    value of a license or royalty agreement, cost reimbursement, damages, and interest. Elements identified related to licensing and royalty are recognized as revenue. Elements identified as reimbursed costs are generally recorded as a reduction to the
    reported expenses. Elements identified as damages or interest are generally recorded in other income in the condensed consolidated statement of operations.&lt;/div&gt;

Deposits held with these financial institutions may exceed the amount of insurance provided on such
      deposits. A portion of those balances are insured by the Federal Deposit Insurance Corporation, or FDIC. During the three months ended March 31, 2022, we had, at times, funds that were uninsured. We do not believe that we are subject to any unusual
      financial risk beyond the normal risk associated with commercial banking relationships. We have not experienced any losses on our deposits of cash and cash equivalents.&lt;/div&gt;

      used in operations when events and changes in circumstances indicate that the carrying amount of an asset might not be recoverable, but not less than annually. Recoverability is measured by comparison of the anticipated future net undiscounted cash
      flows to the related assets&#x2019; carrying value. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the projected discounted future net cash flows
      arising from the asset.&lt;/div&gt;

      method. The asset and liability method requires the recognition of deferred tax assets and liabilities for expected future tax consequences of temporary differences that currently exist between the tax basis and financial reporting basis of our
      assets and liabilities. We calculate current and deferred tax provisions based on estimates and assumptions that could differ from actual results reflected on the income tax returns filed during the following years. Adjustments based on filed returns
      are recorded when identified in the subsequent years. The effect on deferred taxes for a change in tax rates is recognized in income in the period that the tax rate change is enacted. In assessing our deferred tax assets, we consider whether it is
      more likely than not that all or some portion of the deferred tax assets will not be realized.&lt;/div&gt;

&lt;div&gt;&lt;span style="font-weight: normal; color: rgb(0, 0, 0); font-family: 'Times New Roman'; font-size: 10pt; font-style: normal; font-variant: normal; text-transform: none;"&gt; &lt;/span&gt;&lt;/div&gt;

      &lt;/span&gt; &lt;/div&gt;

&lt;div style="text-align: justify; font-family: 'Times New Roman'; font-size: 10pt; font-weight: normal; color: rgb(0, 0, 0); font-style: normal; font-variant: normal; text-transform: none;"&gt;A valuation allowance is provided for deferred income tax
      assets when, in our judgment, based upon currently available information and other factors, it is more likely than not that all or a portion of such deferred income tax assets will not be realized. The determination of the need for a valuation
      allowance is based on an on-going evaluation of current information including, among other things, historical operating results, estimates of future earnings in different taxing jurisdictions and the expected timing of the reversals of temporary
      differences. We believe the determination to record a valuation allowance to reduce a deferred income tax asset is a significant accounting estimate because it is based, among other things, on an estimate of future taxable income in the United States
      and certain other jurisdictions, which is susceptible to change and may or may not occur, and because the impact of adjusting a valuation allowance may be material. In determining when to release the valuation allowance established against our net
      deferred income tax assets, we consider all available evidence, both positive and negative. We continually assess our ability to generate sufficient taxable income during future periods in which our deferred tax assets may be realized. If and when we
      believe it is more likely than not that we will recover our deferred tax assets, we will reverse the valuation allowance as an income tax benefit in our statements of operations.&lt;/div&gt;

&lt;div style="text-align: justify; color: rgb(0, 0, 0); font-family: 'Times New Roman',Times,serif; font-size: 10pt;"&gt;We account for our uncertain tax positions in accordance with U.S. GAAP, which utilizes a two-step approach to evaluate tax positions.
      Step one, recognition, requires evaluation of the tax position to determine if based solely on technical merits it is more likely than not to be sustained upon examination. Step two, measurement, is addressed only if a position is more likely than
      not to be sustained. In step two, the tax benefit is measured as the largest amount of benefit, determined on a cumulative probability basis, which is more likely than not to be realized upon ultimate settlement with tax authorities. If a position
      does not meet the more likely than not threshold for recognition in step one, no benefit is recorded until the first subsequent period in which the more likely than not standard is met, the issue is resolved with the taxing authority, or the statute
      of limitations expires. Positions previously recognized are derecognized when we subsequently determine the position no longer is more likely than not to be sustained. Evaluation of tax positions, their technical merits, and measurements using
      cumulative probability are highly subjective management estimates. Actual results could differ materially from these estimates.&lt;/div&gt;

        compensation costs on a straight-line basis over the requisite service period of the award, which is generally a vesting term of 4
        years. We recognize forfeitures, if any, when they occur. In addition, we record stock-based compensation expense for awards granted to non-employees at fair value of the consideration received or the fair value of the equity instruments issued, as
        they vest, over the performance period (See Note 5 - Stock-Based Compensation).&lt;/div&gt;

      transaction between market participants at the measurement date. A fair value hierarchy prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or
      liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). Level 2 measurements utilize either directly or indirectly observable inputs in markets other than quoted prices in active markets.&lt;/div&gt;

      approximate, fair value. When we estimate fair value, we utilize market data or assumptions that we believe market participants would use in pricing the financial instrument, including assumptions about risk and inputs to the valuation technique. We
      use valuation techniques, primarily the income and market approach, which maximizes the use of observable inputs and minimize the use of unobservable inputs for recurring fair value measurements.&lt;/div&gt;

    (&#x201c;FASB&#x201d;) issued Accounting Standards Update (&#x201c;ASU&#x201d;) 2019-12 Income Taxes (Topic 740). The amendments in this ASU simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve
    consistent application of and simplify U. S. GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after
    December 15, 2020. We adopted this ASU on January 1, 2021 and there was no material impact on our financial position or cash flows as a result.&lt;/div&gt;

      with U.S. GAAP. In doing so, we have to make estimates and assumptions that affect our reported amounts of assets, liabilities, revenues, and expenses, as well as related disclosure of contingent assets and liabilities. In some cases, we could
      reasonably have used different accounting policies and estimates. In some cases, changes in the accounting estimates are reasonably likely to occur from period to period. Accordingly, actual results could differ materially from our estimates. To the
      extent that there are material differences between these estimates and actual results, our financial condition or results of operations will be affected. We base our estimates on past experience and other assumptions that we believe are reasonable
      under the circumstances, and we evaluate these estimates on an ongoing basis. We refer to accounting estimates of this type as critical accounting policies and estimates, which we discuss further below. We have reviewed our critical accounting
      policies and estimates with the audit committee of our Board of Directors.&lt;/div&gt;

    for a patent infringement dispute. Proceeds received are allocated to each element identified in the settlement or compensation, based on the fair value of each element. Generally, settlements and compensation may include the following elements: the
    value of a license or royalty agreement, cost reimbursement, damages, and interest. Elements identified related to licensing and royalty are recognized as revenue. Elements identified as reimbursed costs are generally recorded as a reduction to the
    reported expenses. Elements identified as damages or interest are generally recorded in other income in the condensed consolidated statement of operations.&lt;/div&gt;

      method. The asset and liability method requires the recognition of deferred tax assets and liabilities for expected future tax consequences of temporary differences that currently exist between the tax basis and financial reporting basis of our
      assets and liabilities. We calculate current and deferred tax provisions based on estimates and assumptions that could differ from actual results reflected on the income tax returns filed during the following years. Adjustments based on filed returns
      are recorded when identified in the subsequent years. The effect on deferred taxes for a change in tax rates is recognized in income in the period that the tax rate change is enacted. In assessing our deferred tax assets, we consider whether it is
      more likely than not that all or some portion of the deferred tax assets will not be realized.&lt;/div&gt;

&lt;div&gt;&lt;span style="font-weight: normal; color: rgb(0, 0, 0); font-family: 'Times New Roman'; font-size: 10pt; font-style: normal; font-variant: normal; text-transform: none;"&gt; &lt;/span&gt;&lt;/div&gt;

      assets when, in our judgment, based upon currently available information and other factors, it is more likely than not that all or a portion of such deferred income tax assets will not be realized. The determination of the need for a valuation
      allowance is based on an on-going evaluation of current information including, among other things, historical operating results, estimates of future earnings in different taxing jurisdictions and the expected timing of the reversals of temporary
      differences. We believe the determination to record a valuation allowance to reduce a deferred income tax asset is a significant accounting estimate because it is based, among other things, on an estimate of future taxable income in the United States
      and certain other jurisdictions, which is susceptible to change and may or may not occur, and because the impact of adjusting a valuation allowance may be material. In determining when to release the valuation allowance established against our net
      deferred income tax assets, we consider all available evidence, both positive and negative. We continually assess our ability to generate sufficient taxable income during future periods in which our deferred tax assets may be realized. If and when we
      believe it is more likely than not that we will recover our deferred tax assets, we will reverse the valuation allowance as an income tax benefit in our statements of operations.&lt;/div&gt;

&lt;div style="text-align: justify; color: rgb(0, 0, 0); font-family: 'Times New Roman',Times,serif; font-size: 10pt;"&gt;We account for our uncertain tax positions in accordance with U.S. GAAP, which utilizes a two-step approach to evaluate tax positions.
      Step one, recognition, requires evaluation of the tax position to determine if based solely on technical merits it is more likely than not to be sustained upon examination. Step two, measurement, is addressed only if a position is more likely than
      not to be sustained. In step two, the tax benefit is measured as the largest amount of benefit, determined on a cumulative probability basis, which is more likely than not to be realized upon ultimate settlement with tax authorities. If a position
      does not meet the more likely than not threshold for recognition in step one, no benefit is recorded until the first subsequent period in which the more likely than not standard is met, the issue is resolved with the taxing authority, or the statute
      of limitations expires. Positions previously recognized are derecognized when we subsequently determine the position no longer is more likely than not to be sustained. Evaluation of tax positions, their technical merits, and measurements using
      cumulative probability are highly subjective management estimates. Actual results could differ materially from these estimates.&lt;/div&gt;

    (&#x201c;FASB&#x201d;) issued Accounting Standards Update (&#x201c;ASU&#x201d;) 2019-12 Income Taxes (Topic 740). The amendments in this ASU simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve
    consistent application of and simplify U. S. GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after
    December 15, 2020. We adopted this ASU on January 1, 2021 and there was no material impact on our financial position or cash flows as a result.&lt;/div&gt;

&lt;div style="text-align: justify; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;For the three months ended March 31, 2022, we recognized income tax benefit of $1,059 on loss before taxes of $4,379, which is an effective tax
        rate of 24.45%. The effective tax rate was higher than the statutory federal income tax rate primarily due to the effect of research and
        development tax credits. For the three months ended March 31, 2021, income tax benefit was $7,193 on loss before income taxes of $33,636 and an effective tax rate of 21.38%.
        The effective tax rate was higher than the statutory federal income tax rate primarily due to the effect of research and development tax credits.&lt;/div&gt;

&lt;div style="text-align: justify; color: rgb(0, 0, 0); font-family: 'Times New Roman',Times,serif; font-size: 10pt;"&gt;During the three months ended March 31, 2022, our deferred tax asset increased by $1,059 to $17,009. &lt;/div&gt;

&lt;div style="text-align: justify; color: rgb(0, 0, 0); font-family: 'Times New Roman',Times,serif; font-size: 10pt;"&gt;A valuation allowance is provided for deferred tax assets when, in our judgment, based upon currently available information and other
        factors, it is more likely than not that all or a portion of such deferred income tax assets will not be realized. The determination of the need for a valuation allowance is based on an on-going evaluation of current information including, among
        other things, historical operating results, estimates of future earnings in different taxing jurisdictions and the expected timing of the reversals of temporary differences. We believe the determination to record, or reduce, a valuation allowance
        associated with a deferred income tax asset is a significant accounting estimate because it is based, among other things, on an estimate of future taxable income in the United States and certain other jurisdictions, which is susceptible to change
        and may or may not occur, and because the impact of adjusting a valuation allowance may be material. In determining when to release the valuation allowance established against our net deferred income tax assets, we consider all available evidence,
        both positive and negative. We accumulated a net operating loss (&#x201c;NOL&#x201d;) carryforward in the state in which we were once headquartered, which will begin to expire in &lt;span style="-sec-ix-hidden:Fact_bd581b5b582441fc94cd11a40324bd0d"&gt;2029&lt;/span&gt;; none of the NOL carryforward is included in our deferred tax asset because we currently have no operations in the state where such accumulated.&lt;/div&gt;

      &lt;/div&gt;

&lt;div style="font-family: 'Times New Roman'; font-size: 10pt; font-style: normal; text-align: justify;"&gt;Our tax years for 2005 and forward are subject to examination by the U.S. tax authority and various state tax authorities. These years are open due
        to NOLs, and tax credits generated in these years were utilized in 2020. The statute of limitation for these years shall expire three years after the date of filing 2020 income tax returns. &lt;/div&gt;

&lt;div&gt;&lt;span style="background-color: rgb(255, 255, 255); font-weight: normal; color: rgb(0, 0, 0); font-family: 'Times New Roman'; font-size: 10pt; font-style: normal; font-variant: normal; text-transform: none;"&gt;&lt;br/&gt;

        recognize the financial statement effects of a tax position when it is more likely than not, based on the technical merits, that the position will be sustained upon examination. At December 31, 2021 and March 31, 2022, we have no uncertain tax positions. Our policy is to recognize interest and penalties accrued on uncertain tax positions as a component of income tax
        expense. We had no accrued interest or penalties related to uncertain tax positions at March 31, 2022.  &lt;/div&gt;

      plan for employees and others called the VirnetX Holding Corporation 2013 Equity Incentive Plan (the &#x201c;2013 Plan&#x201d;), which has been approved by our stockholders. To the extent that any award should expire, become un-exercisable or is otherwise
      forfeited, the shares subject to such award will again become available for issuance under the 2013 Plan. The 2013 Plan provides for the granting of stock options and restricted stock units purchase rights (&#x201c;RSUs&#x201d;) to our employees and consultants.
      Stock options granted under the 2013 Plan may be incentive stock options or nonqualified stock options. Incentive stock options (&#x201c;ISOs&#x201d;) may only be granted to our employees (including officers and directors). Nonqualified stock options (&#x201c;NSOs&#x201d;) and
      stock purchase rights may be granted to our employees and consultants. The 2013 Plan expires in 2023.&lt;/div&gt;

        the grant date was estimated utilizing the Black-Scholes valuation model with the following weighted average assumptions (i) dividend yield on our common stock of 0 percent (ii) expected stock price volatility of 97 percent (iii) a risk-free interest rate of 0.27 percent and (iv) and expected option term of 5
        years.&lt;/span&gt;&lt;/div&gt;

        November 6, 2012, when we had filed a complaint against Apple in United States District Court (&#x201c;USDC&#x201d;) in which we alleged that Apple infringed on certain of our patents, (U.S. Patent Nos. 6,502,135, 7,418,504, 7,921,211 and 7,490,151). We sought
        damages and injunctive relief. The accused products include the iPhone 5, iPod Touch 5th Generation, iPad 4th Generation, iPad mini, and the latest Macintosh computers. Post-trial motions hearing was held on July 18, 2018. On August 31, 2018, the
        USDC entered a Final Judgment and issued its Memorandum Opinion and Order regarding post-trial motions, affirming the jury&#x2019;s verdict of $502,600
        and granting VirnetX motions for supplemental damages, a sunset royalty, and the royalty rate of $1.20 per infringing iPhone, iPad and
        Mac products, pre-judgment and post-judgment interest and costs. Apple filed a notice of appeal with the USCAFC in the Apple II case.&lt;/div&gt;

        USCAFC docketed the appeal as Case No. 19-1050 - VirnetX Inc. v. Apple Inc. On January 24, 2019 Apple filed its opening brief. We filed our response brief on March 1, 2019. Apple filed its reply brief on April 5, 2019. The oral arguments were heard
        on October 4, 2019. On November 22, 2019, the USCAFC issued an opinion affirming the district court&#x2019;s findings that Apple is precluded from making certain invalidity arguments and that Apple infringed the &#x2018;135 and &#x2018;151 patents; reversing the USDC&#x2019;s
        finding that Apple infringed the &#x2018;504 and &#x2018;211 patents; and remanding the case for proceedings on damages. Apple sought panel and en banc rehearing, which the USCAFC denied on February 10, 2020.&lt;/div&gt;

        the USDC issued a scheduling order for the parties to brief the court about the need for a new trial for recalculating the damages. We filed our motion for entry of judgment on February 28, 2020. The arguments on this matter were heard on April 14,
        2020. In its order, unsealed on May 1, 2020, the USDC denied VirnetX&#x2019;s motion for entry of a new judgment based on the prior jury verdict and ordered a new jury trial on damages. On August 10, 2020, the USDC granted Apple&#x2019;s motion for continuance
        and reset the date to October 26, 2020. On October 30, 2020, a jury returned a $502,800 verdict in favor of VirnetX based on Apple&#x2019;s
        infringement of two network security patents: VirnetX US Patents No. 6,502,135 and No. 7,490,151. The jury verdict called for damages of
        $0.84 per accused device since the 2013 launch of Apple&#x2019;s iOS 7 operating system and represents 598,629,580 infringing units from US sales only. On January 15, 2021, the district court denied Apple&#x2019;s motion for judgment as a matter of law, and on February 4, 2021, Apple
        filed a notice of appeal to the USCAFC. &lt;br/&gt;

          its responsive brief on July 26, 2021. Apple filed its reply brief on September 13, 2021. The briefing is complete, and we are awaiting the court order with the schedule for oral arguments in this matter.&lt;/div&gt;

          IPR2016-00062 involving our U.S. Patent No. 6,502,135, and an appeal of the invalidity findings by the PTAB in inter-partes review proceedings IPR2015-1047, IPR2016- 00063, and IPR2016-00167 involving our U.S. Patent No. 7,490,151. On September
          25, 2020, the USCAFC issued an order consolidating the two appeals. On December 15, 2020, we filed a motion to vacate the PTAB
          decisions below and to remand these appeals to the PTAB. On March 16, 2021, the USCAFC denied the motion without prejudice to us raising the challenges made in the motion in our opening brief. Our opening brief was filed on June 7, 2021.&lt;/span&gt;&lt;/div&gt;

&lt;div style="text-align: justify; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;On June 23, 2021, the USCAFC entered an order directing us (and parties in other appeals that raised Appointments Clause challenges) to
          file a brief explaining how they believe their cases should proceed in light of the Supreme Court&#x2019;s decision in&#160;United States v. Arthrex, Inc., 141 S. Ct. 1970 (2021). On July 7, 2021, we filed a brief in response to the court&#x2019;s order. Other
          parties, including the U.S. Patent and Trademark Office (&#x201c;USPTO&#x201d;) filed their responses on July 21, 2021. On August 19, 2021, USCAFC issued an order remanding these appeals for the limited purpose of allowing VirnetX the opportunity to request
          rehearing of the PTAB&#x2019;s final written decisions by the Director of the USPTO. The USCAFC retained jurisdiction over the appeals in the meantime. On September 20, 2021, we filed our requests for Director rehearing with the USPTO. On October 29,
          2021, our requests for Director rehearing were denied. We subsequently filed an amended opening brief to the USCAFC on December 10, 2021, the other parties filed response briefs on February 2, 2022, and we filed a reply brief on February 22,
          2022. All the briefings have been completed. We are awaiting the court order with the schedule for oral arguments in this matter. &lt;/div&gt;

&lt;div style="text-align: justify; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;On September 22, 2017, we filed with the USCAFC an appeal of the invalidity findings by the PTAB in inter-partes review proceeding
            IPR2016-00693 involving our U.S. Patent No. 7,418,504, and an appeal of the invalidity findings by the PTAB in inter-partes review proceeding IPR2016-00957 involving our U.S. Patent No. 7,921,211. On September 16, 2021, USCAFC issued an order
            remanding these appeals for the limited purpose of allowing VirnetX the opportunity to request rehearing of the PTAB&#x2019;s final written decisions by the Director of the USPTO. The USCAFC retained jurisdiction over the appeals in the meantime. On
            October 18, 2021, we filed our requests for Director rehearing with the USPTO. On January 7, 2022, our requests for Director rehearing were denied. On January 21, 2022, we informed the USCAFC about the denial of Director rehearing and requested
            that the court dismiss the appeal involving IPR2016-00957 as moot and vacate the PTAB&#x2019;s underlying decision. On April 4, 2022, the USCAFC vacated the PTAB&#x2019;s decision in IPR2016-00957 and remanded Appeal No. 17-2594 with instructions to dismiss.
            In the April 4, 2022 order, the USCAFC further set a briefing schedule, with VirnetX&#x2019;s opening brief currently due June 17, 2022.&lt;/div&gt;

        law firm of McKool Smith, P.C. (&#x201c;McKool&#x201d;) filed a Demand for Arbitration against VirnetX, Inc. with the American Arbitration Association (&#x201c;AAA&#x201d;). In its demand, McKool claimed that a retention agreement it entered into in 2010 with VirnetX entitled
        it to a contingency fee arising from the recent 2020 payment made in the Apple I case. McKool claimed it was owed approximately $36,300
        (or 8% of the Apple I payment). We filed a general response with the AAA denying McKool&#x2019;s claim and contested the matter vigorously. An
        evidentiary hearing was held on the matter during the week of February 22, 2021 and the parties submitted additional briefings. On April 19, 2021, the arbitrator awarded McKool $36,323 in damages, plus pre-judgment interest in the amount of 5% simple
        interest from March 23, 2020 to April 18, 2021, and post-judgment interest in the amount of 5%, compounded annually, until payment of
        the award. We accrued the resulting $38,284 as of March 31, 2021 and paid that amount to McKool on April 20, 2021. &lt;span style="font-weight: bold;"&gt;This matter is now closed.&lt;/span&gt;&lt;/div&gt;

        intellectual property infringement claims may also be available to us against certain other companies who have the resources to defend against any such claims. Although we believe these potential claims are likely valid, commencing a lawsuit can be
        expensive and time-consuming, and there is no assurance that we could prevail on such potential claims if we made them. In addition, bringing a lawsuit may lead to potential counterclaims which may distract our management and our other resources,
        including capital resources, from efforts to successfully commercialize our products.&lt;/div&gt;

&lt;div style="text-align: justify; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;Basic earnings per share are based on the weighted average number of common shares outstanding for the period. Diluted earnings per share are based on the

      higher than the closing price of our stock at the end of each reporting period. &lt;span style="font-family: 'Times New Roman', Times, serif; font-size: 10pt; color: #000000;"&gt;The following table shows the computation of basic and diluted earnings per share for&#160;the three months ended March 31, 2022 and 2021 (in thousands, except per share amounts): &lt;/span&gt;&lt;/div&gt;
