Note 1. General

Overview

Vringo, Inc., together with its consolidated subsidiaries (“Vringo” or the “Company”), is engaged in the development and monetization of intellectual property worldwide. The Company's intellectual property portfolio consists of over 600 patents and patent applications covering telecom infrastructure, internet search and mobile technologies. The Company’s patents and patent applications have been developed internally or acquired from third parties. In potential acquisitions, the Company seeks to purchase all of, or interests in, technology and intellectual property in exchange for cash, the Company’s securities and/or interests in the monetization of those assets. Revenue from this aspect of Vringo’s business can be generated through licensing and litigation efforts.

Prior to December 31, 2013, the Company operated a global platform for the distribution of mobile social applications and the services that it developed. On February 18, 2014, the Company executed the sale of its mobile social application business to InfoMedia Services Limited (“InfoMedia”), receiving an 8.25% ownership interest in InfoMedia as consideration. As part of the transaction, the Company has the opportunity to license certain intellectual property assets and support InfoMedia to identify and protect new intellectual property.

Infrastructure Patents

The Company’s infrastructure patents are primarily made up of a patent portfolio purchased from Nokia Corporation (“Nokia”) in 2012. This patent portfolio is comprised of 124 patent families with counterparts in certain jurisdictions world-wide and encompass technologies relating to telecom infrastructure, including communication management, data and signal transmission, mobility management, radio resources management and services. Declarations were filed by Nokia indicating that 31 of the 124 patent families acquired may be essential to wireless communications standards. The Company also owns other acquired infrastructure patent portfolios and has filed over 60 internally developed patent applications. As one of the means of realizing the value of the patents on telecom infrastructure, the Company has filed a number of suits against ZTE Corporation (“ZTE”), ASUSTeK Computer Inc. (“ASUS”), and certain of their subsidiaries, affiliates and other companies in the United States, European jurisdictions, India, Australia, Brazil, and Malaysia alleging infringement of certain U.S., European, Indian, Australian, Brazilian, and Malaysian patents. In response, ZTE Corporation or its affiliates have filed a number of counterclaims and other responsive cases in various countries such as the United States, certain European jurisdictions, the People’s Republic of China and others.

To date, in connection with the suits filed against ZTE, Vringo patents have been found to be infringed in the United Kingdom (“UK”) and Germany, and preliminary relief has been granted in India, Brazil, Romania, and the Netherlands. Separately, Vringo has entered into settlement and license agreements with ADT, Tyco, D-Link, and Belkin.

Search Patents

On September 15, 2011, the Company’s wholly-owned subsidiary, I/P Engine, Inc. (“I/P Engine”), initiated litigation against AOL Inc., Google, Inc., IAC Search & Media, Inc., Gannett Company, Inc., and Target Corporation (collectively, the “Defendants”) for infringement of claims of certain of its owned patents. Trial commenced during 2012, and, on November 6, 2012, the jury ruled in favor of I/P Engine and against the Defendants. After upholding the validity of the patents-in-suit, and determining that the asserted claims of the patents were infringed by the Defendants, the jury found that reasonable royalty damages should be based on a “running royalty,” and that the running royalty rate should be 3.5%. The jury also awarded I/P Engine a total of approximately $30,500. In January 2014, the United States District Court, Eastern District of Virginia (the “District Court”) ordered that I/P Engine recover an additional sum of $17,320 from the Defendants for supplemental damages and prejudgment interest. Further, the District Court ruled that the appropriate ongoing royalty rate for Defendants' continued infringement of the patents-in-suit is a rate of 6.5% of the 20.9% royalty base previously set by the District Court. These rulings were appealed by the Defendants and the oral argument was heard before the United States Court of Appeals for the Federal Circuit (“Federal Circuit”) on May 6, 2014.

On August 15, 2014, the Federal Circuit reversed the judgment of the District Court by holding that the claims of the patents-in-suit asserted by the Company against the Defendants are invalid for obviousness. The Company filed a petition with the Federal Circuit on October 15, 2014 seeking en banc review of the decision. On October 20, 2014, the Federal Circuit invited the defendants/appellants to respond to the petition. On December 15, 2014, the Federal Circuit denied I/P Engine's petition for rehearing of the case en banc and consequently, the Company announced that I/P Engine will seek review by the Supreme Court of the United States (“Supreme Court”) of the Federal Circuit’s decision. On May 14, 2015, I/P Engine filed a petition for a writ of certiorari with the Supreme Court, which requests review of the Federal Circuit’s decision.

Financial condition

As of June 30, 2015, the Company had a cash balance of $20,227. The Company’s average monthly cash spent in operations for the six month periods ended June 30, 2015 and 2014 was approximately $1,285 and $2,159, respectively. In addition, the Company holds $2,117 in deposits with courts related to proceedings in Germany, Brazil, Romania, and Malaysia. As of June 30, 2015 and December 31, 2014, the Company’s total stockholders' equity was $20,396 and $31,180, respectively. The decrease in stockholders’ equity since December 31, 2014 is mainly due to the operating loss during the six month period ended June 30, 2015.

On May 4, 2015 (the “Closing Date”), the Company entered into a securities purchase agreement with certain institutional investors in a registered direct offering of $12,500 of Senior Secured Convertible Notes (the “Notes”) and warrants to purchase up to 5,375,000 shares of the Company’s common stock. On the Closing Date, the Company issued the Notes, which are convertible into shares of the Company’s common stock at $1.00 per share, bear 8% interest and mature in 21 months from the date of issuance, unless earlier converted. In addition, the Company issued 5,375,000 warrants to purchase shares of the Company’s common stock, which are exercisable at $1.00 per share and are exercisable for a period of five years. In connection with the issuance of the Notes and warrants, the Company received net cash proceeds of $12,425 on May 5, 2015. The Company’s obligations under the outstanding Notes are secured by a first priority perfected security interest in substantially all of the Company’s U.S. assets. In addition, stock of certain subsidiaries of the Company has been pledged. The outstanding Notes contain customary events of default, as well as covenants which include restrictions on the assumption of new debt by the Company.

The principal amount of the outstanding Notes will be repaid monthly, and the Company may make such payments and related interest payments in cash or, subject to certain conditions, in registered shares of the Company’s common stock, at its election. If the Company chooses to repay the Notes in shares of its common stock, the shares will be issued at a 15% discount, based on the then-current market price data of the Company’s common stock. The Company may also repay the Notes in advance of the maturity schedule subject to early repayment penalties.

The Company’s operating plans include efforts to increase revenue through the licensing of its intellectual property, strategic partnerships, and litigation, when required, which may be resolved through a settlement or collection. Disputes regarding the assertion of patents and other intellectual property rights are highly complex and technical. The majority of the Company’s expenditures consist of costs related to the Company’s litigation campaigns. In the cases against ZTE and ASUS, the Company incurred costs during the first half of 2015 related to the preparation and filing of briefs and other court documents, as well as case preparation and management. A large percentage of these costs were incurred in the UK and the U.S. In civil law jurisdictions, such as Germany, France, Spain, and others, the majority of costs are incurred in the early stages of litigation. With respect to the Company’s litigation in such countries, the respective campaigns are currently in the later stages and therefore the Company has already incurred the large majority of the related anticipated costs. As such, based on the Company’s plans, costs in these jurisdictions are projected to be lower in the remainder of 2015 and other future periods.

Despite the Company’s plans, its legal proceedings may continue for several years and may require significant expenditures for legal fees and other expenses. Further, should the Company be deemed the losing party in certain of its litigations, it may be liable for some or all of its opponents’ legal fees. In addition, in connection with litigation, the Company has made several affirmative financial guarantees to courts around the world, and might face the need to make additional guarantees in the future.

In addition, the Company’s plans to continue to expand its planned operations through acquisitions and monetization of additional patents, other intellectual property or operating businesses may be time consuming, complex and costly to consummate. The Company may utilize many different transaction structures in its acquisitions and the terms of such acquisition agreements tend to be heavily negotiated. The Company’s future ability to raise capital, if necessary, may be limited. Even if the Company is able to acquire particular patents or other intellectual property assets, there is no guarantee that it will generate sufficient revenue related to those assets to offset the acquisition costs. Therefore, no assurance can be given at this time as to whether the Company will be able to achieve its objectives or whether it will have the sources of liquidity for follow through with its operating plans.

In addition, until the Company generates sufficient revenue, the Company may need to raise additional funds, which may be achieved through the issuance of additional equity or debt, or through loans from financial institutions. There can be no assurance, however, that any such opportunities will materialize. The Company may also be able to raise additional funds through the exercise of its outstanding warrants and options, however, substantially all of such outstanding equity instruments are currently “out of the money.”

As a result of the events and circumstances described above, including the cash proceeds received in connection with the May 2015 financing transaction and the Company’s operating plans, which include paying the principal and interest related to the Notes in shares of the Company’s common stock, the Company believes that it currently has sufficient cash to continue its current operations for at least the next twelve months.

Accounting Policies [Abstract]

Accounting and Reporting Policies

Note 2. Accounting and Reporting Policies

(a) Basis of presentation and principles of consolidation

The accompanying interim consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) for interim financial information and the instructions to Rule 10-01 of Regulation S-X, and should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2014. All adjustments that, in the opinion of management, are necessary for a fair presentation for the periods presented have been reflected by the SEC. Such adjustments are of a normal, recurring nature. The results of operations for the three month and six month periods ended June 30, 2015 are not necessarily indicative of the results that may be expected for the entire fiscal year or for any other interim period. All significant intercompany balances and transactions have been eliminated in consolidation.

(b) Use of estimates

The preparation of accompanying consolidated financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenues and expenses for the periods presented. Actual results may differ from such estimates. Significant items subject to such estimates and assumptions include the Company’s intangibles assets, the useful lives of the Company’s intangible assets, the valuation of the Company’s derivative warrants, the valuation of stock-based compensation, deferred tax assets and liabilities, income tax uncertainties and other contingencies.

(c) Translation into U.S. dollars

The Company conducts certain transactions in foreign currencies, which are recorded at the exchange rate as of the transaction date. All exchange gains and losses occurring from the re-measurement of monetary balance sheet items denominated in non-U.S. dollar currencies are reflected as non-operating income or expense in the consolidated statements of operations.

(d) Cash and cash equivalents

The Company invests its cash in money market funds with financial institutions. The Company has established guidelines relating to diversification and maturities of its investments in order to minimize credit risk and maintain high liquidity of funds. All highly liquid investments with original maturities of three months or less at acquisition date are considered cash equivalents.

(e) Derivative instruments

The Company recognizes all derivative instruments as either assets or liabilities in the consolidated balance sheets at their respective fair values. The Company's derivative instruments have been recorded as liabilities at fair value, and are revalued at each reporting date, with changes in the fair value of the instruments included in the consolidated statements of operations as non-operating income (expense). The Company reviews the terms of features embedded in non-derivative instruments to determine if such features require bifurcation and separate accounting as derivative financial instruments. Equity–linked derivative instruments are evaluated in accordance with FASB Accounting Standard Codification 815-40, Contracts in an Entity’s Own Equity to determine if such instruments are indexed to the Company’s own stock and qualify for classification in equity.

(f) Intangible assets

Intangible assets include purchased patents which are recorded based on the cost to acquire them. These assets are amortized over their remaining estimated useful lives, which are periodically evaluated for reasonableness. The Company’s intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. In assessing the recoverability of the Company's intangible assets, the Company must make estimates and assumptions regarding future cash flows and other factors to determine the fair value of the respective assets. These estimates and assumptions could have a significant impact on whether an impairment charge is recognized and also the magnitude of any such charge. Fair value estimates are made at a specific point in time, based on relevant information. These estimates are subjective in nature and involve uncertainties and matters of significant judgments and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates. If these estimates or material related assumptions change in the future, the Company may be required to record impairment charges related to its intangible assets.

(g) Revenue recognition

Revenue from patent licensing and enforcement is recognized if collectability is reasonably assured, persuasive evidence of an arrangement exists, the sales price is fixed or determinable and delivery of the service has been rendered. The Company uses management's best estimate of selling price for individual elements in multiple-element arrangements, where vendor specific evidence or third party evidence of selling price is not available.

Currently, the Company’s revenue arrangements provide for the payment of contractually determined fees and other consideration for the grant of certain intellectual property rights related to the Company’s patents. These rights typically include some combination of the following: (i) the grant of a non-exclusive, retroactive and future license to manufacture and/or sell products covered by patents, (ii) the release of the licensee from certain claims, and (iii) the dismissal of any pending litigation. The intellectual property rights granted typically extend until the expiration of the related patents. Pursuant to the terms of these agreements, the Company has no further obligation with respect to the grant of the non-exclusive retroactive and future licenses, covenants-not-to-sue, releases, and other deliverables, including no express or implied obligation on the Company’s part to maintain or upgrade the related technology, or provide future support or services. Generally, the agreements provide for the grant of the licenses, covenants-not-to-sue, releases, and other significant deliverables upon execution of the agreement, or upon receipt of the upfront payment. As such, the earnings process is complete and revenue is recognized upon the execution of the agreement, upon receipt of the upfront fee, and when all other revenue recognition criteria have been met.

(h) Operating legal costs

Operating legal costs mainly include expenses incurred in connection with the Company’s patent licensing and enforcement activities, patent-related legal expenses paid to external patent counsel (including contingent legal fees), licensing and enforcement related research, consulting and other expenses paid to third parties, as well as related internal payroll expenses and stock-based compensation. In addition, amounts received by the Company for reimbursements of legal fees in connection with its litigation campaigns are recorded in Operating legal costs as an offset to legal expense.

(i) Stock-based compensation

Stock-based compensation is recognized as an expense in the consolidated statements of operations and such cost is measured at the grant-date fair value of the equity-settled award. The fair value of stock options is estimated at the date of grant using the Black-Scholes-Merton option-pricing model. The expense is recognized on a straight-line basis, over the requisite service period. The Company uses the simplified method to estimate the expected term of options due to insufficient history and high turnover in the past. Since the Company lacks sufficient history, expected volatility is estimated based on a weighted average historical volatility of the Company and comparable entities with publicly traded shares. The risk-free rate for the expected term of the option is based on the U.S. Treasury yield curve at the date of grant.

(j) Recently Issued Accounting Pronouncements

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which impacts virtually all aspects of an entity's revenue recognition. The core principle of the new standard is that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance was amended in July 2015 and is effective for annual reporting periods beginning after December 15, 2017. The Company is currently evaluating the impact of the adoption on its consolidated financial statements.

In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements (Topic 205): Going Concern. The new standard provides guidance around management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and to provide related footnote disclosures. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016 and early adoption is permitted. The Company is currently evaluating the impact of the adoption on its consolidated financial statements.

In November 2014, the FASB issued ASU 2014-16, Derivatives and Hedging: Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share is More Akin to Debt or to Equity. The new standard clarifies how current U.S. GAAP should be interpreted in evaluating the economic characteristics and risks of a host contract in a hybrid financial instrument that is issued in the form of a share. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015 and early adoption is permitted. The Company is currently evaluating the impact of the adoption on its consolidated financial statements.

In April 2015, the FASB issued ASU No. 2015-03, Simplifying the Presentation of Debt Issuance Costs, which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the corresponding debt liability, consistent with debt discounts. The new standard does not change the amortization of debt issuance costs, which are reported as interest expense in the consolidated statements of operations. This guidance is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years and early adoption is permitted. The Company is currently evaluating the impact of the adoption on its consolidated financial statements.

Certain balances have been reclassified to conform to presentation requirements.

	$	16,008	$	17,625

The Company’s patents consist of three major patent portfolios, which were acquired from third parties, as well as a number of internally developed patents. The costs related to internally developed patents are expensed as incurred.

In August 2012, the Company purchased a portfolio from Nokia consisting of various patents and patent applications as described in Note 1. The total consideration paid for the portfolio was $22,000 and the Company capitalized certain costs related to the acquisition of patents in the total amount of $548. Under the terms of the purchase agreement, to the extent that the gross revenue generated by such portfolio exceeds $22,000, the Company is obligated to pay a royalty of 35% of such excess. The Company has not recorded any amounts in respect of this contingent consideration, as both the amounts of future potential revenue, if any, and the timing of such revenue cannot be reasonably estimated.

The Company’s patents are amortized over their expected useful lives (i.e., through the expiration date of the patent). During the three and six month periods ended June 30, 2015, the Company recorded amortization expense of $813 and $1,617, respectively, related to its patents. During the three and six month periods ended June 30, 2014, the Company recorded amortization expense of $968 and $1,925, respectively, related to its patents.

During the third quarter of 2014, the Company determined that there were impairment indicators related to certain of its patents. A significant factor that was considered when making this determination included the announcement of the Federal Circuit’s decision on August 15, 2014. The Company concluded that this factor was deemed a “triggering” event requiring that the related patent assets be tested for impairment during the third quarter of 2014. In performing this impairment test, the Company determined that the patent portfolio containing the patents-in-suit in I/P Engine's litigation against AOL Inc., Google Inc. et al, which represents an asset group, was subject to impairment testing. In the first step of the impairment test, the Company utilized its projections of future undiscounted cash flows based on the Company’s existing plans for the patents. As a result, it was determined that the Company’s projections of future undiscounted cash flows were less than the carrying value of the asset group. Accordingly, the Company performed the second step of the impairment test to measure the potential impairment by calculating the asset group’s fair value. This resulted in an impairment of $1,355 during the third quarter of 2014, related to the asset group, which represents the difference between the fair value and the carrying value of the asset group. There were no impairment charges related to the Company’s patents during the six month periods ended June 30, 2015 and 2014.

Earnings Per Share, Basic and Diluted [Abstract]

Net Loss per Common Share

Note 4. Net Loss per Common Share

Basic net loss per share is computed by dividing the net loss for the period by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by dividing the net loss for the period by the weighted-average number of shares of common stock plus dilutive potential common stock considered outstanding during the period. However, as the Company generated net losses in all periods presented, some potentially dilutive securities that relate to the continuing operations, including certain warrants and stock options, were not reflected in diluted net loss per share because the impact of such instruments was anti-dilutive. The table below presents the computation of basic and diluted net losses per common share:

Senior Secured Convertible Notes

Note 6. Senior Secured Convertible Notes

On May 4, 2015 (the “Closing Date”), the Company entered into a securities purchase agreement with certain institutional investors in a registered direct offering of $12,500 of Senior Secured Convertible Notes (the “Notes”) and warrants to purchase 5,375,000 shares of the Company’s common stock. On the Closing Date, the Company issued the Notes, which are convertible into shares of the Company’s common stock at $1.00 per share, bear 8% interest and mature in 21 months from the date of issuance, unless earlier converted. In addition, the Company issued 5,375,000 warrants to purchase shares of the Company’s common stock, which are exercisable at $1.00 per share and are exercisable for a period of five years, beginning on the six month and one day anniversary of their date of issuance. In connection with the issuance of the Notes and warrants, the Company received net cash proceeds of $12,425 on May 5, 2015. The Company also incurred third party costs directly associated with the issuance of Notes of $218, which are capitalized as debt issuance costs and included in Other assets, and are amortized over the term of the Note. The Company’s obligations under the outstanding Notes are secured by a first priority perfected security interest in substantially all of the Company’s U.S. assets. In addition, stock of certain subsidiaries of the Company has been pledged. The outstanding Notes contain customary events of default, as well as covenants which include restrictions on the assumption of new debt by the Company. As of June 30, 2015, all covenants were met and there were no events of default.

The principal amount of the outstanding Notes will be repaid monthly, and the Company may make such payments and related interest payments in cash or, subject to certain conditions, in registered shares of the Company’s common stock, at its election. On each of the principal installment dates, the Company’s scheduled principal amortization payment will be an amount equal to $595. If the Company chooses to repay the Notes in shares of its common stock, the shares will be issued at a 15% discount, based on the then-current market price data of the Company’s common stock. The Company may also repay the Notes in advance of the maturity schedule subject to early repayment penalties. The holders of the Notes may accelerate up to six principal installment payments on each of the principal installment dates. The Company may choose to settle such amounts in cash or shares issued at a 15% discount, based on the then-current market price data of the Company’s common stock. Further, the Notes contain provisions that under certain events of default, as defined in the agreement, the amount owed could increase by amounts ranging from 115% to 120% of the face value depending on when the event occurred, and additionally, the interest rates would increase to 16.5% per annum upon the occurrence and continuance of an event of default. In addition, the Company may choose to repay the Notes early at a premium ranging from 115% to 120% of the face value depending on when the election is made.

The 8% interest will be paid quarterly, starting July 1, 2015, and the Company may make such payments in cash or registered shares of the Company’s common stock, at its election. If the Company chooses to repay the Notes in shares of its common stock, the shares for the payment of interest will be issued at the then-current market price of the Company’s common stock.

Upon issuance of the Notes on May 4, 2015, the Company recorded the following as of June 30, 2015:

Net cash proceeds from the Notes ($12,500 less investors issuance costs of $75)	$	12,425
Debt Discount:
May 2015 Warrants		1,717
Conversion feature		1,244
		2,961
Net Total – May 4, 2015		9,464
Debt discount amortization		289
Debt repayments		(1,191)
Net Total – June 30, 2015		8,562
Short-term portion		8,111
Long-term portion		451

The debt discount is attributable to the value of the separately accounted for Conversion feature and May 2015 Warrants issued in connection with the financing. The embedded Conversion feature derivatives relate to the conversion option, redemption in case of an event of default, and redemption in the case of a change in control features of the Notes. The embedded derivatives were evaluated under ASC topic 815-15, were bifurcated from the debt host, and were classified as liabilities in the consolidated balance sheet. The debt discount is amortized using the effective interest method over the term of the Notes. For the three and six months ended June 30, 2015, the Company recorded $289 of debt discount amortization included in interest expense on the consolidated statements of operations. In addition, the Company recorded $21 amortization of debt issuance costs included in interest expense and recorded an interest accrual of $155 included in Accounts payable and accrued expenses as of June 30, 2015.

During the three months ended June 30, 2015, the Company made principal payments in the aggregate amount of $1,191. The Company elected to make these principal payments in shares of the Company’s common stock, which are issued at a 15% discount to the market price. As such, the Company issued 2,300,000 shares in lieu of principal payments and recorded $210 as extinguishment of debt expense on the consolidated statements of operations.Subsequent to June 30, 2015, the Company made additional principal payments in the aggregate amount of $1,524 and an interest payment of $155 in shares of common stock, the latter of which had been accrued as of June 30, 2015.

See Note 7 and 8 for further detail on the fair value of the May 2015 Warrants and Conversion feature.

Fair Value Measurements [Abstract]

Fair Value Measurements

Note 7. Fair Value Measurements

The Company measures fair value in accordance with FASB Accounting Standard Codification (“ASC”) 820-10, Fair Value Measurements and Disclosures. FASB ASC 820-10 clarifies that fair value is an exit price, representing the amount that would be received by selling an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability. As a basis for considering such assumptions, FASB ASC 820-10 establishes a three-tier value hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value:

Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date.

Level 2: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability.

Level 3: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at measurement date.

The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

The following table presents the placement in the fair value hierarchy of liabilities measured at fair value on a recurring basis as of June 30, 2015 and December 31, 2014:

			Fair value measurement at reporting date using
			Quoted prices in
			active markets		Significant other		Significant
			for identical		observable		unobservable
		Balance		assets (Level 1)		inputs (Level 2)		inputs (Level 3)
June 30, 2015:
May 2015 Warrants	$	1,507	$	—	$	—	$	1,507
Conversion feature	$	759	$	—	$	—	$	759

December 31, 2014:
Conversion Warrants, the derivative Reload Warrants and the derivative Series 1 Warrants	$	175	$	—	$	—	$	175

The Company measures its derivative liabilities at fair value. The Conversion Warrants, the derivative Reload Warrants and the derivative Series 1 Warrants were classified within Level 3 because they were valued using the Black-Scholes-Merton and the Monte-Carlo models, as these warrants included down-round protection clauses, which utilize significant inputs that are unobservable in the market. On January 1, 2015, the down-round protection clauses associated with all of the Company’s outstanding derivative warrants expired and, as a result, these warrants no longer meet the criteria for liability classification. As such, the related liabilities were revalued as of January 1, 2015 and the balance of $175, which was comprised of long-term derivative liability warrants of $174 and short-term derivative liability warrants of $1, was reclassified to equity.

The May 2015 Warrants were classified within Level 3 because they were valued using the Black-Sholes-Merton model, which utilizes significant inputs that are unobservable in the market. They are recorded as derivative liability warrants as they are freestanding instruments and there are several features within the warrants that may require the Company to cash settle or partially cash settle. In particular, the Company may have to cash settle, partially cash settle, or make cash payments to the holders including cash settlement upon exercise when insufficient shares are authorized to be issued, and that the Company is obligated to issue registered shares when the warrants are exercised. The derivative liability is initially measured at fair value and marked to market at each balance sheet date.

The Conversion feature was classified within Level 3 because it was valued using the Monte-Carlo model, which utilizes significant inputs that are unobservable in the market. The embedded Conversion feature derivatives relate to the conversion option, redemption in case of an event of default, and redemption in the case of a change in control features of the Notes. The Conversion feature was separated from the host debt contract and accounted for as a derivative instrument because the feature is not clearly and closely related to the debt host and a separate instrument with the same terms as the embedded derivative would be a derivative instrument.

In addition to the above, the Company’s financial instruments as of June 30, 2015 and December 31, 2014 consisted of cash, cash equivalents, receivables, accounts payable and deposits. The carrying amounts of all the aforementioned financial instruments approximate fair value because of the short-term maturities of these instruments.

The following table summarizes the changes in the Company’s liabilities measured at fair value using significant unobservable inputs (Level 3) during the six month period ended June 30, 2015:

	Conversion Warrants, the derivative Reload Warrants and the derivative Series 1 Warrants		May 2015 Warrants		Conversion feature
December 31, 2014	$	175	$	—	$	—
Reclassification of derivative Reload Warrants and Series 1 Warrants to equity warrants		(175)		—		—
Issuance of Notes and derivative warrants on May 4, 2015		—		1,717		1,244
Gain on revaluation of warrants and conversion feature		—		(210)		(485)
June 30, 2015		—		1,507		759

Valuation processes for Level 3 Fair Value Measurements

Fair value measurement of the derivative warrant liabilities falls within Level 3 of the fair value hierarchy. The fair value measurements are evaluated by management to ensure that changes are consistent with expectations of management based upon the sensitivity and nature of the inputs.

December 31, 2014:

Description	Valuation technique	Unobservable inputs	Range
Conversion Warrants, derivative Reload Warrants and	Black-Scholes-Merton and the	Volatility		56.55% - 77.06%
derivative Series 1 Warrants	Monte-Carlo models	Risk free interest rate		0.13% - 0.87%
		Expected term, in years		0.48 - 2.55
		Dividend yield		0%

June 30, 2015:

Description	Valuation technique	Unobservable inputs	Range
Conversion feature	Monte-Carlo model	Volatility		91.53%
		Risk free interest rate		0.44%
		Expected term, in years		1.50
		Conversion price		$1.00

May 2015 Warrants	Black-Scholes-Merton	Volatility		77.69%
		Risk free interest rate		1.70%
		Expected term, in years		4.84
		Dividend yield		0.00%

Sensitivity of Level 3 measurements to changes in significant unobservable inputs

The inputs to estimate the fair value of the Company’s derivative warrant liabilities and Conversion feature were the current market price of the Company’s common stock, the exercise price of the warrants and Conversion feature, their remaining expected term, the volatility of the Company’s common stock price and the risk-free interest rate over the expected term. Significant changes in any of those inputs in isolation can result in a significant change in the fair value measurement.

Generally, an increase in the market price of the Company’s shares of common stock, an increase in the volatility of the Company’s shares of common stock, and an increase in the remaining term of the warrants and Conversion feature would each result in a directionally similar change in the estimated fair value of the Company’s warrants. Such changes would increase the associated liability while decreases in these assumptions would decrease the associated liability. An increase in the risk-free interest rate or a decrease in the differential between the warrants’ and Conversion feature’s exercise prices and the market price of the Company’s shares of common stock would result in a decrease in the estimated fair value measurement and thus a decrease in the associated liability. The Company has not, and does not plan to, declare dividends on its common stock, and as such, there is no change in the estimated fair value of the warrants and Conversion feature due to the dividend assumption.

Commitments and Contingencies [Abstract]

Commitments and Contingencies

Note 10. Commitments and Contingencies

Litigation and legal proceedings

The Company retains the services of professional service providers, including law firms that specialize in intellectual property licensing, enforcement and patent law. These service providers are often retained on an hourly, monthly, project, contingent or a blended fee basis. In contingency fee arrangements, a portion of the legal fee is based on predetermined milestones or the Company’s actual collection of funds. The Company accrues contingent fees when it is probable that the milestones will be achieved and the fees can be reasonably estimated.

The Company’s subsidiaries have filed patent infringement lawsuits against ZTE and its subsidiaries in the UK, France, Germany, Netherlands, Australia, India, Brazil, Malaysia, and Romania, and against ASUS and its subsidiaries in Germany, Spain and India. In such jurisdictions, an unsuccessful plaintiff may be required to pay a portion of the other party’s legal fees. In addition, the Company may be required to grant additional written commitments, as necessary, in connection with its commenced proceedings against ZTE and its subsidiaries in various countries. However, if the Company were successful on any court applications or the entirety of any litigation, the defendants may be responsible for a substantial portion of the Company’s legal fees. In response, ZTE Corporation or its affiliates have filed a number of counterclaims and other responsive cases in various countries such as the United States, certain European jurisdictions, the People’s Republic of China, and others.

Pursuant to negotiation with ZTE’s UK subsidiary, the Company made two written commitments, in November 2012 and May 2013, representing payment should a liability by Vringo Infrastructure arise as a result of the two cases it has filed. Each of the cases filed include three patents which the Company has alleged are infringed by ZTE. The defendants estimated the total possible liability to be no more than approximately $2,900 for each case. The Company recorded its best estimate of its liability in respect of ZTE’s legal fees, which is presented in Other liabilities included in the consolidated balance sheets as of June 30, 2015 and December 31, 2014, but believes that the ultimate liability will be significantly less.

In March 2014, the Company withdrew one of the patents included in the first case against ZTE’s UK subsidiary. ZTE withdrew its invalidity counterclaims.

In November 2014, with respect to another patent included in the first case, the Court found that Vringo’s patent is valid as amended and infringed by ZTE. ZTE did not appeal the decision, and the decision is final.

On February 17, 2015, Vringo withdrew its infringement claims against ZTE on three of the four remaining European Patents in suit in the second litigation in the UK. ZTE subsequently withdrew its invalidity counterclaims in respect of these three patents.

On April 10, 2015, Vringo and ZTE reached an agreement in relation to the remaining European Patent in issue (EP (UK) 1 330 933) in the second patent case in the UK in which the parties will withdraw their respective claims and counterclaims.

On September 13, 2013 and January 28, 2014, Vringo Germany filed two suits in the Regional Court of Düsseldorf, alleging infringement of two European patents by ZTE’s German subsidiary. Those cases were heard by the Court on November 27, 2014. On January 22, 2015, the Court issued its judgment, finding that ZTE does not infringe either patent. On February 17, 2015, Vringo filed notices of appeal for each patent. The appeal process is anticipated to take at least one year.

On May 5, 2014, the Company deposited a bond of €1,000 (approximately $1,109 as of June 30, 2015) to enforce an injunction against ZTE in Germany. On May 20, 2015, the Company paid an additional €50 (approximately $57 as of June 30, 2015) to enforce review of accounting records. Should the injunction be successfully overturned on appeal, the Company may be obligated to compensate ZTE for any damages allegedly suffered as a result of the enforcement of the injunction, which would be ascertained through separate damages proceedings. Should the judgment which granted the injunction be affirmed on appeal, however, the amount paid as security would be returnable to the Company in full. The Company has assessed the likelihood of the injunction being successfully overturned on appeal as remote.

In Brazil, as a condition of the relief requested, the Company deposited R$2,020 on April 17, 2014 (approximately $640 as of June 30, 2015), as a surety against the truth of allegations contained in the complaint. This deposit is returnable at the end of the litigation unless ZTE is the prevailing party and proves that actual material damages were suffered while the requested relief was in place. The Company has assessed the likelihood of ZTE doing so as remote.

In Romania, Vringo Infrastructure filed a patent infringement lawsuit against ZTE in the Bucharest Tribunal Civil Section on June 23, 2014 and the Court granted an ex-parte preliminary injunction, ordering ZTE to cease any importation, exportation, introduction on the market, offer for sale, storage, sale, trade, distribution, promotion, or any other business activity regarding the infringing product. The Company deposited a bond of €243 on February 11, 2015 (approximately $270 as of June 30, 2015) with the Court in order to continue to enforce the injunction.

The bond deposits in Germany and Romania and the surety deposit in Brazil are included in Deposits with courts in the consolidated balance sheets as of June 30, 2015 and December 31, 2014.

In the People’s Republic of China, ZTE has filed 33 reexamination requests of Vringo’s Chinese patents with the Patent Re-Examination Board (“PRB”) of the State Intellectual Property Office of the People’s Republic of China. To date, the PRB has upheld the validity of 17 of the Company’s patents, partially upheld the validity of two of the Company’s patents, and has held that 12 of the Company’s patents are invalid. The Company has filed appeals on the PRB’s decision on the patents that have been held invalid. The appeal process is expected to take at least one year. The remaining reexamination requests remain pending, with decisions expected to be rendered on a rolling basis.

On February 21, 2014, ZTE filed a civil complaint against the Company and certain of its subsidiaries in the Shenzhen Intermediate Court alleging that the Company violated China’s antimonopoly laws. The Company received notice of the action on June 26, 2014. The Company intends to vigorously contest all aspects of this action in the appropriate manner. On July 28, 2014, the Company filed a motion to have this complaint dismissed due to lack of jurisdiction. On August 6, 2014, the Court dismissed this motion. The Company filed an appeal of the dismissal, which was denied by the Court. The Court conducted a hearing on May 29, 2015 for the parties to submit any evidence on which they intended to rely. During this hearing, ZTE amended its complaint to increase its damages demand. As a result, the Company filed a motion contesting the jurisdiction of the Court, which was denied. The Company’s appeal of the jurisdictional question is pending. Trial on the merits, which had been scheduled to begin on June 9, 2015 has been postponed pending Vringo’s appeal. The appellate process is expected to take several months. The Company has not made a determination of what the potential liability may be should it lose the case in China.

Leases

In July 2012, the Company signed a rental agreement for its corporate executive office in New York for an annual rental fee of approximately $137 (subject to certain adjustments) which was to expire in September 2015. In January 2014, the Company entered into an amended lease agreement with the landlord for a different office space within the same building. The initial annual rental fee for this new office is approximately $403 (subject to certain future escalations and adjustments) beginning on August 1, 2014, which was the date when the new office space was available. This lease will expire in October 2019. Rent expense for operating leases for the three and six month periods ended June 30, 2015 were $91 and $183, respectively. Rent expense for operating leases for the three and six month periods ended June 30, 2014 were $70 and $182, respectively.

Risks and Uncertainties

6 Months Ended

Jun. 30, 2015

Risks and Uncertainties [Abstract]

Risks and Uncertainties

Note 11. Risks and Uncertainties

(a)

New legislation, regulations or rulings that impact the patent enforcement process or the rights of patent holders could negatively affect the Company’s current business model. 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 the Company’s ability to assert its patent or other intellectual property rights.

(b)

The patents owned by the Company are presumed to be valid and enforceable. As part of the Company’s ongoing legal proceedings, the validity and/or enforceability of its patents is often challenged in a court or an administrative proceeding. On August 15, 2014, the Federal Circuit reversed a judgment of the United States District Court for the Eastern District of Virginia by holding that the asserted claims of the patents-in-suit in I/P Engine's litigation against AOL Inc., Google Inc. et al. are invalid for obviousness. Additionally, during the second half of 2014, the Patent Re-Examination Board of the State Intellectual Property Office of the People’s Republic of China held that twelve of the Company's Chinese patents, and partial claims on two of the Company’s other Chinese patents, are invalid. The Company is appealing these decisions. The Company’s other patents have not been declared to be invalid or unenforceable to date.

(c)

Financial instruments which potentially subject the Company to significant concentrations of credit risk consist principally of cash and cash equivalents. The Company maintains its cash and cash equivalents with various major financial institutions. These major financial institutions are located in the United States and the Company’s policy is designed to limit exposure to any one institution.

(d)

A portion of the Company’s expenses are denominated in foreign currencies. If the value of the U.S. dollar weakens against the value of these currencies, there will be a negative impact on the Company’s operating costs. In addition, the Company is subject to the risk of exchange rate fluctuations to the extent it holds monetary assets and liabilities in these currencies.

(e)

The Notes are repaid on a monthly basis in cash or shares at the Company’s election. If the Company is unable to satisfy certain equity conditions, it will be required to pay all amounts due on any installment date in cash. The Company’s ability to timely repay the Notes, to redeem the Notes, and to fund working capital needs and planned capital expenditures depends on its ability to generate cash flow in the future. If the Company is unable to generate sufficient cash flow or otherwise obtain funds necessary to make required payments, or if the Company fails to comply with the various requirements of the Notes, the Company would be in default, which would permit the holders of the Notes to accelerate the maturity of the Notes and cause a default under the Notes. Any default under the Notes could have a material adverse effect on the Company’s business, results of operations and financial condition.

(f)

The Company may choose to raise additional funds in connection with any potential acquisition of patent portfolios or other intellectual property assets or operating businesses. In addition, the Company may also need additional funds to respond to business opportunities and challenges, including its ongoing operating expenses, protection of its assets, development of new lines of business and enhancement of its operating infrastructure. While the Company may need to seek additional funding, it may not be able to obtain financing on acceptable terms, or at all. If the Company is unable to obtain additional funding on a timely basis, it may be required to curtail or terminate some of its business plans.

- 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.
