We seek to license our technology, including GABRIEL Connection Technology™, to various original equipment manufacturers, or OEMs, that use our technologies in the development and manufacturing of their own products within the IP-telephony, mobility, fixed-mobile convergence and unified communications markets. Prior to 2012 our revenue was limited to an insignificant amount of software royalties pursuant to the terms of a single license agreement. During 2012 we had revenues from settlements of patent infringement disputes whereby we received consideration for past sales of licensees that utilized our technology, where there was no prior patent license agreement (see "Revenue Recognition). |

| Summary of Significant Accounting Policies [Abstract] | |
| Summary of Significant Accounting Policies | Note 2 - Summary of Significant Accounting Policies Basis of Presentation The consolidated financial statements include the accounts of VirnetX Holding Corporation and all wholly-owned subsidiaries. All material intercompany accounts and transactions have been eliminated. Certain prior year amounts have been reclassified to conform to current year presentations. Use of Estimates We have made a number of estimates and assumptions related to the reporting of assets, liabilities, revenues and expenses to prepare these financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) as delineated by the Financial Accounting Standards Board (FASB) in its Accounting Standards Codification (ASC). Generally, assets and liabilities that are subject to estimation and judgment include the fair value of stock-based compensation, the fair value of our warrant liability and deferred income taxes. While actual results could differ, we believe such estimates to be reasonable. Revenue Recognition We derive our revenue from patent licensing. The timing and amount of revenue recognized from each licensee depends upon a variety of factors, including the specific terms of each agreement and the nature of the deliverables and obligations. Such agreements can be complex and may or may not include multiple elements. These agreements may include, without limitation, elements related to the settlement of past patent infringement liabilities, up-front and non-refundable license fees for the use of patents, patent licensing royalties on covered products sold by licensees, and the compensation structure and ownership of intellectual property rights associated with contractual technology development arrangements. Beginning January 1, 2011, licensing agreements are accounted for under the FASB revenue recognition guidance, "Revenue Arrangements with Multiple Deliverables." This guidance requires consideration to be allocated to each element of an agreement that has stand-alone value using the relative fair value method. In other circumstances, such as those agreements involving consideration for past and expected future patent royalty obligations, after consideration of the particular facts and circumstances, the appropriate recording of revenue between periods may require the use of judgment. In all cases, revenue is only recognized after all of the following criteria are met: (1) written agreements have been executed; (2) delivery of technology or intellectual property rights has occurred or services have been rendered; (3) fees are fixed or determinable; and (4) collectability of fees is reasonably assured. Patent License Agreements: Upon signing a patent license agreement, we provide the licensee permission to use our patented technology in specific applications. We account for patent license agreements in accordance with the guidance for revenue arrangements with multiple deliverables and the guidance for revenue recognition. We have elected to utilize the leased-based model for revenue recognition, with revenue being recognized over the expected period of benefit to the licensee. Under our patent license agreements, we typically receive one or a combination of the following forms of payment as consideration for permitting our licensees to use our patented inventions in specific applications and products: Consideration for Past Sales: Consideration related to a licensee's product sales from prior periods may result from a negotiated agreement with a licensee that utilized our patented technology prior to signing a patent license agreement with us or from the resolution of a disagreement or arbitration with a licensee over the specific terms of an existing license agreement. We may also receive royalty for past sales in connection with the settlement of patent litigation where there was no prior patent license agreement. These amounts are negotiated based upon application of a royalty rate to historical sales prior to the execution of the license agreement. In each of these cases, since delivery has occurred, we record the consideration as revenue when we have obtained a signed agreement, identified a fixed or determinable price, and determined that collectability is reasonably assured. Current Royalty Payments: These are ongoing royalty payments covering a licensee's obligations to us related to its sales of covered products in the current contractual reporting period. Licensees that owe Current Royalty Payments are obligated to provide us with quarterly or semi-annual royalty reports that summarize their sales of covered products and their related royalty obligations to us. We expect to receive these royalty reports subsequent to the period in which our licensees' underlying sales occurred. As a result, it is impractical for us to recognize revenue in the period in which the underlying sales occur, and, in most cases, we will recognize revenue in the period in which the royalty report is received and other revenue recognition criteria are met due to the fact that without royalty reports from our licensees, our visibility into our licensees' sales is limited. Current Royalty Payments will be calculated based on related per-unit sales of covered products. Revenues recognized during 2012 resulted from settlements of patent infringement disputes (see Note 15 "Litigation") whereby we received consideration for past sales of licensees that utilized our technology, where there was no prior patent license agreement. Cash and Cash Equivalents We consider all highly liquid investments purchased with original maturities of three months or less at the date of purchase to be cash equivalents. Our cash and cash equivalents are not subject to significant interest rate risk due to the short maturities of these investments. Investments Investments are classified as available-for-sale and are recorded at fair market value. Unrealized gain and losses are reported as other comprehensive income. Realized gains and losses are recorded in income in the period they are realized. The Company's investments consist of debt securities and certificates of deposit with maturity dates primarily less than nine months. Property and Equipment Property and equipment are stated at historical cost, less accumulated depreciation and amortization. Depreciation and amortization are computed using the accelerated and straight line methods over the estimated useful lives of the assets, which range from five to seven years. Repair and maintenance costs are charged to expense as incurred. Concentration of Credit Risk and Other Risks and Uncertainties Our cash and cash equivalents are primarily maintained at two major financial institutions in the United States. 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 year ended December 31, 2012, 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. Fair Value The carrying amounts of our financial instruments, including cash equivalents, accounts payable, and accrued liabilities, approximate fair value because of their generally short maturities. Intangible Assets We record intangible assets at cost, less accumulated amortization. Amortization of intangible assets is provided over their estimated useful lives, which can range from 3 to 15 years, on either a straight-line basis or as revenue is generated by the assets. Impairment of Long-Lived Assets We identify and record impairment losses on long-lived assets 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' 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. Research and Development Research and development costs include expenses paid to outside development consultants and compensation related expenses for our engineering staff. Research and development costs are expensed as incurred. Income Taxes The provision for income taxes is computed using the asset and liability method, under which deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities, and for operating losses and tax credit carry forwards. Deferred tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for the years in which those tax assets are expected to be realized or settled. The Company records a valuation allowance to reduce deferred tax assets to the amount that is believed more likely than not to be realized. In addition, the calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws. We are subject to examinations by the Internal Revenue Service ("IRS") and other taxing jurisdictions on various tax matters, including challenges to various positions we assert in our filings. In the event that the IRS or another taxing jurisdiction levies an assessment in the future, it is possible the assessment could have a material adverse effect on our consolidated financial condition or results of operations. The financial statement recognition of the benefit for a tax position is dependent upon the benefit being more likely than not to be sustainable upon audit by the applicable tax authority. If this threshold is met, the tax benefit is then measured and recognized at the largest amount that is greater than 50 percent likely of being realized upon ultimate settlement. In the event that the IRS or another taxing jurisdiction levies an assessment in the future, it is possible the assessment could have a material adverse effect on our consolidated financial condition or results of operations. See Note 11, "Income Taxes" for additional information. Derivative Instruments Our Series I Warrants are accounted for as derivative instruments as a result of an anti-dilution provision which, in accordance with U.S. GAAP, prevents them from being considered indexed to our stock and qualified for an exception to derivative accounting. We recognize derivative instruments as either assets or liabilities on the accompanying Consolidated Balance Sheets at fair value. We record changes in the fair value (i.e., gains or losses) of the derivatives in the accompanying Consolidated Statements of Operations. Stock-Based Compensation We account for stock-based compensation using the fair value recognition method in accordance with U.S. GAAP. We recognize these compensation costs net of the applicable forfeiture rate and recognize the compensation costs for only those shares expected to vest on a straight-line basis over the requisite service period of the award, which is generally the option vesting term of 4 years. We estimate the forfeiture rate based on our historical experience if any. See Note 6 - Stock-Based Compensation for additional information concerning our share-based compensation awards. In addition, as required we record stock and options 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. Earnings Per Share Basic earnings per share are computed by dividing earnings available to common stockholders by the weighted average number of outstanding common shares during the period. Diluted earnings per share is computed by dividing net income by the weighted average number of shares outstanding during the period increased to include the number of additional shares of common stock that would have been outstanding if the potentially dilutive securities had been issued. During 2012 and 2011 we had incurred losses; therefore the effect of any common stock equivalent would be anti-dilutive during these periods. New Accounting Pronouncements In May 2011, the FASB issued a new accounting standard update, which amends the fair value measurement guidance and includes some enhanced disclosure requirements. The most significant change in disclosures is an expansion of the information required for Level 3 measurements based on unobservable inputs. The standard is effective for fiscal years beginning after December 15, 2011. This standard did not have an impact on our consolidated results of operations and financial position, when adopted on January 1, 2012. On January 31, 2013 the FASB issued an update to an existing accounting standard the objective of which is to clarify the scope of Accounting Standards Update No. 2011-11, Disclosures about Offsetting Assets and Liabilities, would apply to derivatives including bifurcated embedded derivatives, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions that are either offset in accordance with Section 210-20-45 or Section 815-10-45 or are subject to a master netting arrangement or similar agreement. Management does not expect adoption to have an effect on our consolidated results of operations and financial position. On February 5, 2013 the FASB issued an amendment to a prior update of existing standards. The amendments in this update supersede and replace the presentation requirements for reclassifications out of accumulated other comprehensive income in ASUs 2011-05 (issued in June 2011) and 2011-12 (issued in December 2011) for all public and private organizations. The amendments would require an entity to provide additional information about reclassifications out of accumulated other comprehensive income. Management does not expect adoption to have an effect on our consolidated results of operations and financial position. Impact of Recently Issued Accounting Pronouncements New accounting guidance was issued in 2011 to require more prominent disclosure of comprehensive income. This guidance was effective for us beginning in the first quarter of 2012, and requires the presentation of net income, items of other comprehensive income and total comprehensive income in one continuous statement or two separate but consecutive statements. We elected to present two separate but consecutive statements. New accounting guidance was issued in February 2013 that requires the presentation of information about the amounts reclassified out of accumulated other comprehensive income by component for each reporting period. This guidance is effective for us in the first quarter of 2013 and is not expected to have an effect on our financial condition or results of operations. In addition, new accounting guidance was issued in 2011 and 2012 which was intended to reduce the complexity and costs of performing annual goodwill and indefinite-lived intangible asset testing by allowing companies the option to make a qualitative evaluation about the likelihood of impairment to determine whether it should calculate the fair value of a reporting unit or the indefinite-live intangible asset. The adoption of this guidance did not have an effect on the Company's financial condition or results of operations. |

| Stock Plan | Note 5 - Stock Plan In 2005, VirnetX, Inc. adopted the 2005 Stock Plan (the "Plan"), which was assumed by us upon the closing of the transaction between VirnetX Holding Corporation and VirnetX, Inc. on July 5, 2007. Our Board of Directors renamed this Plan the VirnetX Holding Corporation 2007 Stock Plan and our stockholders approved the Plan at our 2008 annual stockholders' meeting. The Plan provides for the issuance of up to 11,624,469 shares of our common stock. 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 Plan. The Plan provides for the granting of stock options and restricted stock purchase rights (RSU) to our employees and consultants. Stock options granted under the Plan may be incentive stock options or nonqualified stock options. Incentive stock options ("ISO") may only be granted to our employees (including officers and directors). Nonqualified stock options ("NSO") and stock purchase rights may be granted to our employees and consultants. The Plan will expire 10 years after it was approved by our Board of Directors. Options may be granted under the 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 ISO or 85% of 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% 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 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.

| Stock-Based Compensation | Note 6 - Stock-Based Compensation The following table summarizes information about stock options outstanding at December 31, 2012:
The following table summarizes activity under the Plan for the indicated periods:
Intrinsic value is calculated as the difference between the per share market price of our common stock on the last trading day of 2012, which was $29.28, and the exercise price of the options. For options exercised, the intrinsic value is the difference between market price and the exercise price on the date of exercise. We received cash proceeds of $1,691 and $1,068 from stock options exercised in 2012 and 2011, respectively. The total intrinsic value of options exercised was $11,509, $8,050 and $7,350 during the years ended December 31, 2012, 2011 and 2010, respectively. The aggregate intrinsic value of options exercisable at December 31, 2012 was $99,723. Stock-based compensation expense is included in general and administrative expense for each period as follows:
As of December 31, 2012, there was $12,883 of unrecognized stock-based compensation expense expected to be recognized related to unvested employed stock options and $2,891 of unrecognized stock-based compensation expense to be recognized related to unvested RSU's. These costs are expected to be recognized over a weighted-average period of 1.36 and 2.81 years. The fair value of each option grant was estimated on the date of grant using the Black-Scholes option pricing model using the following weighted average assumptions:
Based on the Black-Scholes option pricing model, the weighted average estimated fair value of employee stock options granted was $23.15, $21.13 and $4.83 during the years ended December 31, 2012, 2011 and 2010 respectively. The expected life was determined using the simplified method outlined in ASC 718, taking the average of the vesting term and the contractual term of the option. Expected volatility of the stock options was based upon historical data and other relevant factors, such as the volatility of comparable publicly-traded companies at a similar stage of life cycle. We have not provided an estimate for forfeitures because we have no history of forfeited options and believe that all outstanding options at December 31, 2012, will vest. In the future, the Company may change this estimate based on actual and expected future forfeiture rates. |

| Earnings Per Share | Note 7 - Earnings Per Share Basic earnings per share are based on the weighted average number of shares outstanding for a period. Diluted earnings per share are based upon the weighted average number of shares and potentially dilutive common shares outstanding. Potential common shares outstanding principally include stock options, under our stock plan and warrants. During 2012 and 2011, we incurred losses; therefore the effect of any common stock equivalent would be anti-dilutive during those periods. The table below sets forth the basic loss per share calculations:
Options to purchase 2.3 million shares at prices ranging from $0.24 to $6.47 were excluded from the diluted earnings per share calculation for the year ending December 31, 2010 because they would have been anti-dilutive due to their exercise prices exceeding the average market prices for the period. |

| Income Taxes | Note 11 - Income Taxes The (benefit) provision for income taxes is comprised of the following:
A reconciliation of the United States federal statutory income tax rate to our effective income tax rate is as follows:
Deferred tax assets (liabilities) consist of the following:
In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of deferred assets will not be realized. The ultimate realization of the deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Based on the available objective evidence, we believe it is more likely than not that the net deferred tax assets as of December 31, 2012 will not be fully realizable. Accordingly, management has established a full valuation allowance against its net deferred tax assets at December 31, 2012. The net change in the total valuation allowance for the year ended December 31, 2012 was an increase of $802. At December 31, 2012, the Company has federal and state net operating loss carry forwards of approximately $912 and $39,432, respectively expiring in 2027 and 2012, respectively. At December 31, 2012, the Company has federal research and development credits carry forwards of approximately zero expiring beginning in 2031. Internal Revenue Code Section 382 places a limitation (the "Section 382 Limitation") on the amount of taxable income can be offset by net operating loss carry forwards after a change in control (generally greater than 50% change in ownership) of a loss corporation. California has similar rules. Our capitalization described herein may have resulted in such a change. Generally, after a control change, a loss corporation cannot deduct net operating loss carry forward in excess of the Section 382 Limitation. Management has analyzed the utilization of its net operating loss carry forward against taxable income in future periods and determined on a more likely than not basis it will be able to use all its recognized net operating losses before they expire. We are required to 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. As a result, we have provided contingent reserve under ASC 740-10 of $128 and $128 at December 31, 2012 and December 31, 2011, respectively. Our tax returns are subject to review by various tax authorities. The returns are subject to review those from 2005 forward. Our policy is to recognize interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense. We did not have associated accrued interest or penalties nor was any interest expense or penalties recognized during the year ended December 31, 2012. A reconciliation of beginning and ending amounts of unrecognized tax benefits follows:

| Fair Value Measurement | Note 12 - Fair Value Measurement We apply fair value accounting for all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement: Level 1 – Quoted prices in active markets for identical assets or liabilities. Level 2 – Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 – Inputs that are generally unobservable and typically reflect management's estimate of assumptions that market participants would use in pricing the asset or liability. The carrying amounts for cash and cash equivalents, investments in certificates of deposit, accounts payable and accrued expenses approximate their fair values due to the short period of time until maturity. Certificate of deposits: Fair value measured at face value plus accrued interest. Corporate bonds: Fair value measured at the closing price reported on the active market on which the individual securities are traded. Series I Warrants: Fair value measured by using a Binomial valuation model. As of December 31, 2012, the assumptions used to measure fair value of the liability embedded in our outstanding Series I Warrants included a warrant exercise price of $3.59 per share, a common share price of $29.28, a discount rate of 0.72%, and a volatility of 94.15%. As of December 31, 2011, the assumptions used to measure fair value of the liability embedded in our outstanding Series I Warrants included a warrant exercise price of $3.59 per share, a common share price of $24.97, a discount rate of 0.83%, and a volatility of 123%.

The amount of such payments depends upon the type of value generated, and certain categories are subject to maximums and other limitations. As of June 30, 2010, we met our maximum royalty payment requirement; however, SAIC is also entitled under certain circumstances to receive a portion of the proceeds paid to us for certain acquisitions of VirnetX or from the settlement of certain patent infringement claims of ours. As of December 31, 2012, the expected future amortization of the intangible assets is as follows:

| Litigation [Abstract] | |
| Litigation | Note 14 - Litigation We have four intellectual property infringement lawsuits pending against multiple parties in the United States District Court for the Eastern District of Texas, Tyler Division, pursuant to which we allege that these parties infringe on certain of our patents. We seek damages and injunctive relief in all the complaints. We have one complaint with the United States International Trade Commission (ITC) alleging that Apple, Inc. has engaged in unfair trade practices by the importation, sale for importation, and sale after importation of certain devices with secure communication capabilities that infringe one or more claims of our U.S. Patent No. 8,051,181. On February 27, 2013, we announced our intent to withdraw our complaint with the ITC and pursue comprehensive relief from Apple Inc.'s infringement through the district courts. VirnetX Inc. v. Cisco Systems, Inc. et al On August 11, 2010, we initiated a lawsuit by filing a complaint against Aastra, Apple, Cisco, and NEC in the United States District Court for the Eastern District of Texas, Tyler Division, pursuant to which we allege that these parties infringe on certain of our patents. We seek damages and injunctive relief. On February 4, 2011, we amended our original complaint, filed on August 11, 2010, against Aastra, Apple, Cisco and NEC in the United States District Court for the Eastern District of Texas, Tyler Division, to assert U.S. Patent No. 7,418,504 against Apple and Aastra. On April 5, 2011, we again amended our complaint against Aastra, Apple, Cisco and NEC in the United States District Court for the Eastern District of Texas, Tyler Division, to include Apple's iPad 2 in the list of Apple products that are accused of infringing our patents. We also asserted our newly-issued patent, U.S. Patent No. 7,921,211 against all of the defendants in that lawsuit. A claim construction hearing was held on January 5, 2012 and the court issued a Markman ruling on April 25, 2012. Aastra and NEC have signed license agreements with us and we have dismissed the patent infringement cases against them. At the pre-trial hearing, the judge decided to postpone the trial against Cisco to March 4, 2013 and just try the case against Apple. On November 6, 2012, a Jury in the United States Court for the Eastern District of Texas, Tyler Division, awarded us over $368,000,000 in a verdict against Apple Corporation for infringing four of our patents. A post-trial hearing in the case against Apple was held on December 20, 2012. On February 26, 2013, the United States District Court for the Eastern District of Texas, Tyler Division issued its Memorandum Opinion and Order regarding post-trial motions resulting from the prior jury verdict. The Court denied Apple's motion to reduce the damages awarded by the jury for past infringement. The Court further denied Apple's request for a new trial on the liability and damages portions of the verdict. Additionally, the Court granted our motions for pre-judgment interest, post-judgment interest, and post-verdict damages to date. Specifically, the Court ordered that Apple pay $33,561 in daily interest up to final judgment and $330,201 in daily damages for infringement up to final judgment for certain Apple devices included in the verdict. The Court denied our request for a permanent injunction. In doing so, the Court ordered the parties to mediate over a license in the following 45 days for Apple's future infringing use not covered by the Court's Order. If the parties fail to agree to a license, the Court requested that we file the appropriate motion with the Court. The preparations for the jury trial against Cisco on March 4, 2013 are underway. VirnetX Inc. v. Mitel Networks Corporation et al On January 12, 2011, we initiated a lawsuit by filing a complaint against Siemens and Mitel in the United States District Court for the Eastern District of Texas, Tyler Division, pursuant to which we allege that these companies infringe three of our patents. We seek damages and injunctive relief. On April 12, 2011 we again amended our complaint against Siemens and Mitel in the United States District Court for the Eastern District of Texas, Tyler Division, to add Avaya Inc. as a defendant. On July 11, 2012, Mitel Network Corporation signed a license agreement with us and we dismissed the patent infringement case against them. On July 12, 2012 we had a claims construction hearing in this case and a markman order was issued on August 1, 2012. On January 29, 2013 Siemens signed a license agreement with us and we dismissed the patent infringement case against them. The preparations for the jury trial against Avaya on March 4, 2013 are underway. VirnetX Inc. v. Apple, Inc. On November 1, 2011, we initiated a lawsuit against Apple in the United States District Court, Tyler Division, pursuant to which allege that Apple infringes one or more claims of our U.S. Patent No. 8,051,181. We seek damages and injunctive relief. No hearing or trial dates have been set. VirnetX Inc. v. Apple, Inc. On November 6, 2012, we filed a new complaint against Apple Inc., in the United States District Court for the Eastern District of Texas, Tyler Division for willfully infringing four of our patents, U.S. Patent Nos. 6,502,135, 7,418,504, 7,921,211 and 7,490,151, and seeking both 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. Due to their release dates, these products were not included in the previous lawsuit that concluded with a Jury verdict on November 6, 2012 that was subsequently upheld by the United States District Court for the Eastern District of Texas, Tyler Division, on February 26, 2013. ITC Investigation No. 337-TA-858 On July 18, 2012, the Administrative Law Judge (ALJ) assigned to investigate our complaint, against Apple Inc., identified a procedural discrepancy with our complaint and dismissed it. On September 14, 2012, we re-filed our complaint with the ITC jointly with Science Applications International Corporation (SAIC) [NYSE: SAI] to remove a procedural standing issue that was identified as the reason for dismissal of our previous complaint. On October 16, 2012, the United States International Trade Commission (ITC) accepted our complaint and instituted an investigation against Apple and assigned ALJ E. James Gildea to preside over this investigation. Subsequently on October 23, 2012, the ALJ issued an order setting February 21, 2014 as the target date for completion of this investigation. The hearing in-front of ALJ is scheduled for May 20, 2013. On February 27, 2013, we announced our intent to withdraw our complaint with the ITC and pursue comprehensive relief from Apple Inc.'s infringement through the district courts. One or more potential 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 worth pursuing, commencing a lawsuit can be expensive and time-consuming, and there is no assurance that we will prevail on such potential claims. In addition, bringing a lawsuit may lead to potential counterclaims which may preclude our ability to commercialize our initial products, which are currently in development. |

| Subsequent Events [Abstract] | |
| Subsequent Events | Note 16 - Subsequent Event On January 29, 2013, we entered into a License Agreement with Siemens Enterprise Communications GmbH & Co. KG, and Siemens Enterprise Communications Inc.. Under the terms of the Agreement, the Parties have agreed to dismiss the patent infringement case between the Parties and their affiliates before the U.S. District Court for the Eastern District of Texas. On February 26, 2013, the United States District Court for the Eastern District of Texas, Tyler Division issued its Memorandum Opinion and Order regarding post-trial motions resulting from the November 6, 2012 jury verdict against Apple, Inc. The Court denied Apple's motion to reduce the damages awarded by the jury for past infringement. The Court further denied Apple's request for a new trial on the liability and damages portions of the verdict. Additionally, the Court granted our motions for pre-judgment interest, post-judgment interest, and post-verdict damages to date. The Court ordered that Apple pay daily interest up to final judgment and daily damages for infringement up to final judgment for certain Apple devices included in the verdict. The Court denied our request for a permanent injunction. The Court has ordered the parties to mediate over a license in the following 45 days for Apple's future infringing use not covered by the Court's Order. If the parties fail to agree to a license, the Court requested that we file the appropriate motion with the Court for its assistance. There can be no assurance a license agreement can be reached. Due to the remaining uncertainty regarding the conclusion of this litigation, the financial statements do not include any provision for gains or losses regarding this matter. |

| Summary of Significant Accounting Policies [Abstract] | |
| Basis of Presentation | Basis of Presentation The consolidated financial statements include the accounts of VirnetX Holding Corporation and all wholly-owned subsidiaries. All material intercompany accounts and transactions have been eliminated. Certain prior year amounts have been reclassified to conform to current year presentations. |
| Use of Estimates | Use of Estimates We have made a number of estimates and assumptions related to the reporting of assets, liabilities, revenues and expenses to prepare these financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) as delineated by the Financial Accounting Standards Board (FASB) in its Accounting Standards Codification (ASC). Generally, assets and liabilities that are subject to estimation and judgment include the fair value of stock-based compensation, the fair value of our warrant liability and deferred income taxes. While actual results could differ, we believe such estimates to be reasonable. |
| Revenue Recognition | Revenue Recognition We derive our revenue from patent licensing. The timing and amount of revenue recognized from each licensee depends upon a variety of factors, including the specific terms of each agreement and the nature of the deliverables and obligations. Such agreements can be complex and may or may not include multiple elements. These agreements may include, without limitation, elements related to the settlement of past patent infringement liabilities, up-front and non-refundable license fees for the use of patents, patent licensing royalties on covered products sold by licensees, and the compensation structure and ownership of intellectual property rights associated with contractual technology development arrangements. Beginning January 1, 2011, licensing agreements are accounted for under the FASB revenue recognition guidance, "Revenue Arrangements with Multiple Deliverables." This guidance requires consideration to be allocated to each element of an agreement that has stand-alone value using the relative fair value method. In other circumstances, such as those agreements involving consideration for past and expected future patent royalty obligations, after consideration of the particular facts and circumstances, the appropriate recording of revenue between periods may require the use of judgment. In all cases, revenue is only recognized after all of the following criteria are met: (1) written agreements have been executed; (2) delivery of technology or intellectual property rights has occurred or services have been rendered; (3) fees are fixed or determinable; and (4) collectability of fees is reasonably assured. Patent License Agreements: Upon signing a patent license agreement, we provide the licensee permission to use our patented technology in specific applications. We account for patent license agreements in accordance with the guidance for revenue arrangements with multiple deliverables and the guidance for revenue recognition. We have elected to utilize the leased-based model for revenue recognition, with revenue being recognized over the expected period of benefit to the licensee. Under our patent license agreements, we typically receive one or a combination of the following forms of payment as consideration for permitting our licensees to use our patented inventions in specific applications and products: Consideration for Past Sales: Consideration related to a licensee's product sales from prior periods may result from a negotiated agreement with a licensee that utilized our patented technology prior to signing a patent license agreement with us or from the resolution of a disagreement or arbitration with a licensee over the specific terms of an existing license agreement. We may also receive royalty for past sales in connection with the settlement of patent litigation where there was no prior patent license agreement. These amounts are negotiated based upon application of a royalty rate to historical sales prior to the execution of the license agreement. In each of these cases, since delivery has occurred, we record the consideration as revenue when we have obtained a signed agreement, identified a fixed or determinable price, and determined that collectability is reasonably assured. Current Royalty Payments: These are ongoing royalty payments covering a licensee's obligations to us related to its sales of covered products in the current contractual reporting period. Licensees that owe Current Royalty Payments are obligated to provide us with quarterly or semi-annual royalty reports that summarize their sales of covered products and their related royalty obligations to us. We expect to receive these royalty reports subsequent to the period in which our licensees' underlying sales occurred. As a result, it is impractical for us to recognize revenue in the period in which the underlying sales occur, and, in most cases, we will recognize revenue in the period in which the royalty report is received and other revenue recognition criteria are met due to the fact that without royalty reports from our licensees, our visibility into our licensees' sales is limited. Current Royalty Payments will be calculated based on related per-unit sales of covered products. Revenues recognized during 2012 resulted from settlements of patent infringement disputes (see Note 15 "Litigation") whereby we received consideration for past sales of licensees that utilized our technology, where there was no prior patent license agreement. |
| Cash and Cash Equivalents | Cash and Cash Equivalents We consider all highly liquid investments purchased with original maturities of three months or less at the date of purchase to be cash equivalents. Our cash and cash equivalents are not subject to significant interest rate risk due to the short maturities of these investments. |
| Investments | Investments Investments are classified as available-for-sale and are recorded at fair market value. Unrealized gain and losses are reported as other comprehensive income. Realized gains and losses are recorded in income in the period they are realized. The Company's investments consist of debt securities and certificates of deposit with maturity dates primarily less than nine months. |
| Property and Equipment | Property and Equipment Property and equipment are stated at historical cost, less accumulated depreciation and amortization. Depreciation and amortization are computed using the accelerated and straight line methods over the estimated useful lives of the assets, which range from five to seven years. Repair and maintenance costs are charged to expense as incurred. |
| Concentration of Credit Risk and Other Risks and Uncertainties | Concentration of Credit Risk and Other Risks and Uncertainties Our cash and cash equivalents are primarily maintained at two major financial institutions in the United States. 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 year ended December 31, 2012, 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. |
| Fair Value | Fair Value The carrying amounts of our financial instruments, including cash equivalents, accounts payable, and accrued liabilities, approximate fair value because of their generally short maturities. |
| Intangible Assets | Intangible Assets We record intangible assets at cost, less accumulated amortization. Amortization of intangible assets is provided over their estimated useful lives, which can range from 3 to 15 years, on either a straight-line basis or as revenue is generated by the assets. |
| Impairment of Long-Lived Assets | Impairment of Long-Lived Assets We identify and record impairment losses on long-lived assets 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' 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. |
| Research and Development | Research and Development Research and development costs include expenses paid to outside development consultants and compensation related expenses for our engineering staff. Research and development costs are expensed as incurred. |
| Income Taxes | Income Taxes The provision for income taxes is computed using the asset and liability method, under which deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities, and for operating losses and tax credit carry forwards. Deferred tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for the years in which those tax assets are expected to be realized or settled. The Company records a valuation allowance to reduce deferred tax assets to the amount that is believed more likely than not to be realized. In addition, the calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws. We are subject to examinations by the Internal Revenue Service ("IRS") and other taxing jurisdictions on various tax matters, including challenges to various positions we assert in our filings. In the event that the IRS or another taxing jurisdiction levies an assessment in the future, it is possible the assessment could have a material adverse effect on our consolidated financial condition or results of operations. The financial statement recognition of the benefit for a tax position is dependent upon the benefit being more likely than not to be sustainable upon audit by the applicable tax authority. If this threshold is met, the tax benefit is then measured and recognized at the largest amount that is greater than 50 percent likely of being realized upon ultimate settlement. In the event that the IRS or another taxing jurisdiction levies an assessment in the future, it is possible the assessment could have a material adverse effect on our consolidated financial condition or results of operations. See Note 11, "Income Taxes" for additional information. |
| Derivative Instruments | Derivative Instruments Our Series I Warrants are accounted for as derivative instruments as a result of an anti-dilution provision which, in accordance with U.S. GAAP, prevents them from being considered indexed to our stock and qualified for an exception to derivative accounting. We recognize derivative instruments as either assets or liabilities on the accompanying Consolidated Balance Sheets at fair value. We record changes in the fair value (i.e., gains or losses) of the derivatives in the accompanying Consolidated Statements of Operations. |
| Stock-Based Compensation | Stock-Based Compensation We account for stock-based compensation using the fair value recognition method in accordance with U.S. GAAP. We recognize these compensation costs net of the applicable forfeiture rate and recognize the compensation costs for only those shares expected to vest on a straight-line basis over the requisite service period of the award, which is generally the option vesting term of 4 years. We estimate the forfeiture rate based on our historical experience if any. See Note 6 - Stock-Based Compensation for additional information concerning our share-based compensation awards. In addition, as required we record stock and options 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. |
| Earnings Per Share | Earnings Per Share Basic earnings per share are computed by dividing earnings available to common stockholders by the weighted average number of outstanding common shares during the period. Diluted earnings per share is computed by dividing net income by the weighted average number of shares outstanding during the period increased to include the number of additional shares of common stock that would have been outstanding if the potentially dilutive securities had been issued. During 2012 and 2011 we had incurred losses; therefore the effect of any common stock equivalent would be anti-dilutive during these periods. |
| New Accounting Pronouncements | New Accounting Pronouncements In May 2011, the FASB issued a new accounting standard update, which amends the fair value measurement guidance and includes some enhanced disclosure requirements. The most significant change in disclosures is an expansion of the information required for Level 3 measurements based on unobservable inputs. The standard is effective for fiscal years beginning after December 15, 2011. This standard did not have an impact on our consolidated results of operations and financial position, when adopted on January 1, 2012. On January 31, 2013 the FASB issued an update to an existing accounting standard the objective of which is to clarify the scope of Accounting Standards Update No. 2011-11, Disclosures about Offsetting Assets and Liabilities, would apply to derivatives including bifurcated embedded derivatives, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions that are either offset in accordance with Section 210-20-45 or Section 815-10-45 or are subject to a master netting arrangement or similar agreement. Management does not expect adoption to have an effect on our consolidated results of operations and financial position. On February 5, 2013 the FASB issued an amendment to a prior update of existing standards. The amendments in this update supersede and replace the presentation requirements for reclassifications out of accumulated other comprehensive income in ASUs 2011-05 (issued in June 2011) and 2011-12 (issued in December 2011) for all public and private organizations. The amendments would require an entity to provide additional information about reclassifications out of accumulated other comprehensive income. Management does not expect adoption to have an effect on our consolidated results of operations and financial position. Impact of Recently Issued Accounting Pronouncements New accounting guidance was issued in 2011 to require more prominent disclosure of comprehensive income. This guidance was effective for us beginning in the first quarter of 2012, and requires the presentation of net income, items of other comprehensive income and total comprehensive income in one continuous statement or two separate but consecutive statements. We elected to present two separate but consecutive statements. New accounting guidance was issued in February 2013 that requires the presentation of information about the amounts reclassified out of accumulated other comprehensive income by component for each reporting period. This guidance is effective for us in the first quarter of 2013 and is not expected to have an effect on our financial condition or results of operations. In addition, new accounting guidance was issued in 2011 and 2012 which was intended to reduce the complexity and costs of performing annual goodwill and indefinite-lived intangible asset testing by allowing companies the option to make a qualitative evaluation about the likelihood of impairment to determine whether it should calculate the fair value of a reporting unit or the indefinite-live intangible asset. The adoption of this guidance did not have an effect on the Company's financial condition or results of operations. |

- Definition
Tabular disclosure of warrants or rights issued. 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. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.

This element represents the portion of the balance sheet assertion valued at fair value by the entity whether such amount is presented as a separate caption or as a parenthetical disclosure. Additionally, this element may be used in connection with the fair value disclosures required in the footnote disclosures to the financial statements. The element may be used in both the balance sheet and disclosure in the same submission. This item represents Available-for-sale Securities which consist of all investments in certain debt and equity securities neither classified as trading or held-to-maturity securities. A debt security represents a creditor relationship with an enterprise. Debt securities include, among other items, US Treasury securities, US government securities, municipal securities, corporate bonds, convertible debt, commercial paper, and all securitized debt instruments. An equity security represents an ownership interest in an enterprise or the right to acquire or dispose of an ownership interest in an enterprise at fixed or determinable prices. Equity securities include, among other things, common stock, certain preferred stock, warrant rights, call options, and put options, but do not include convertible debt. An entity may opt to provide the reader with additional narrative text to better understand the nature of investments in debt and equity securities which are categorized as Available-for-sale.
