General [Abstract]

General

Note 1. General

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. 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 as consideration (Note 5).

Recent development

On August 15, 2014, the United States Court of Appeals for the Federal Circuit (“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 the Company's wholly-owned subsidiary I/P Engine's litigation against AOL Inc., Google Inc. et al. 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.

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, 2013. The results of operations for the three month and nine month periods ended September 30, 2014 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 valuation of goodwill and 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 remeasurement of monetary balance sheet items denominated in non-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, which are discussed in Notes 6 and 8, 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).

(f) Goodwill

Goodwill is an asset representing the future economic benefits arising from other assets acquired in a business combination that are not individually identified and separately recognized. Goodwill is reviewed for impairment at least annually, and when triggering events occur, in accordance with the provisions of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 350, Intangibles - Goodwill and Other. The Company has one reporting unit for purposes of evaluating goodwill impairment and performs its annual goodwill impairment test on December 31.

The Company has the option to perform a qualitative assessment to determine if an impairment is more likely than not to have occurred. If the Company can support the conclusion that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, the Company would not need to perform the two-step impairment test for the reporting unit. If the Company cannot support such a conclusion or the Company does not elect to perform the qualitative assessment, then the first step of the goodwill impairment test is used to identify potential impairment by comparing the fair value of the reporting unit with its carrying amount, including goodwill. Fair value of the reporting unit is determined using certain valuation techniques, including the estimation of an implied control premium, in addition to the Company’s market capitalization on the measurement date.

If the fair value of the reporting unit exceeds its carrying value, then the second step of the impairment test (measurement) does not need to be performed. If the fair value of the reporting unit is less than its carrying value, an indication of goodwill impairment exists for the reporting unit and the entity must perform the second step of the impairment test. Under the second step, an impairment loss is recognized for any excess of the carrying amount of the reporting unit’s goodwill over the implied fair value of that goodwill. The implied fair value of goodwill is determined by allocating the fair value of the reporting unit in a manner similar to an acquisition price allocation and the residual fair value after this allocation is the implied fair value of the reporting unit goodwill. A significant amount of judgment is required in estimating the fair value of a reporting unit and performing goodwill impairment tests. Refer to Note 3 for further discussion of the interim goodwill impairment test performed by the Company as of September 30, 2014.

(g) 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. Refer to Note 3 for further discussion of an impairment charge recorded by the Company during the quarter ended September 30, 2014 related to its intangible assets.

(h) 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.

(i) 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.

(j) Recently Issued Accounting Pronouncements

In July 2013, the FASB issued Accounting Standards Update (“ASU”) No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, which provides guidance on the presentation of unrecognized tax benefits. This guidance requires an entity to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except as follows: to the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. This guidance is effective beginning January 1, 2014 and is to be applied prospectively with retroactive application permitted. The Company adopted this guidance as of January 1, 2014, as required. There was no material impact of the consolidated financial statements resulting from the adoption.

In April 2014, the FASB issued ASU No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. This guidance changes the criteria for reporting a discontinued operation while enhancing disclosures in this area. This standard will be effective for the Company beginning January 1, 2015. Early adoption of the standard is permitted, but only for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued or available for issuance. The Company is currently evaluating the impact of the adoption on its consolidated financial statements.

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 is effective for annual reporting periods beginning after December 15, 2016. The Company is currently evaluating the impact of the adoption on its consolidated financial statements.

In June 2014, the FASB issued ASU No. 2014-10, Development Stage Entities (Topic 915): Elimination of Certain Financial Reporting Requirements, Including an Amendment to Variable Interest Entities Guidance in Topic 810, Consolidation, which removes the definition of development stage entity, as was previously defined under U.S. GAAP, thereby removing the financial reporting distinction between development stage entities and other reporting entities. In addition, the ASU eliminates the requirements for development stage entities to (i) present inception-to-date information in their financial statements, (ii) label the financial statements as those of a development stage entity, (iii) disclose a description of the development stage activities in which the entity is engaged, and (iv) disclose in the first year in which the entity is no longer a development stage entity that in prior years it had been in the development stage. This guidance is effective for annual reporting periods beginning after December 31, 2014 and early adoption of the standard is permitted. The Company adopted this guidance during the second quarter of 2014.

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.

(k) Reclassification

Certain balances have been reclassified to conform to presentation requirements including discontinued operations.

Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill and Intangible Assets

Note 3. Goodwill and Intangible Assets

Based upon a combination of factors and developments during the third quarter of 2014, including the announcement of the Federal Circuit’s decision on August 15, 2014, described in Note 1, as well as a decline in the Company’s stock price, the Company determined that there were impairment indicators related to its goodwill and certain intangible assets. The Company’s stock price opened at $3.18, reached a low of $0.67, and closed at $0.88 on August 15, 2014. The closing price of the Company’s stock on September 30, 2014 was $0.95. The average closing stock price of the Company from August 15, 2014 through September 30, 2014 was approximately $1.05, ranging from $0.95 to $1.40 during that time period. The Company concluded that these factors and developments were deemed “triggering” events requiring that goodwill and certain of the Company’s intangibles assets be tested for impairment as of September 30, 2014. The results of these impairment tests are discussed below in further detail.

Intangible assets

The following table provides information regarding the Company’s intangible assets, which consist of its patents:

	September 30, 2014		December 31, 2013		Weighted average amortization period (years)
Patents		28,213		28,213		8.9
Less: accumulated amortization		(8,368)		(5,465)
Less: impairment		(1,355)		—
	$	18,490	$	22,748

The Company’s patents are amortized over their expected useful lives (i.e., through the expiration date of the patent). During the three and nine month periods ended September 30, 2014, the Company recorded amortization expense of $978 and $2,903, respectively, related to its patents. During the three and nine month periods ended September 30, 2013, the Company recorded amortization expense of $860 and $2,538, respectively, related to its patents.

In performing the impairment analysis related to the Company’s intangible assets, 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. The impairment charge is included in Amortization and impairment of intangibles in the consolidated statements of operations.

Goodwill

The carrying amount of the Company’s goodwill was $65,757 as of September 30, 2014 and December 31, 2013. The Company performed the first step of the goodwill impairment test as of September 30, 2014 in order to identify potential impairment by comparing the fair value of the reporting unit with its carrying amount, including goodwill. The fair value of the reporting unit was determined with the assistance of a third party valuation specialist using certain valuation techniques, including the estimation of an implied control premium, in addition to the Company’s market capitalization on the measurement date. The implied control premium selected was developed based on certain observable market data of comparable companies. The market capitalization is sensitive to the volatility of the Company’s stock price. Based upon the first step of the goodwill impairment test performed as of September 30, 2014, the Company determined that the fair value of the reporting unit was in excess of its carrying amount by approximately 14% and therefore the second step of the goodwill impairment test was not required.

While the Company believes it has made reasonable estimates and assumptions to calculate the fair value of the reporting unit, it is possible a material change could occur. For instance, a subsequent decline in the Company’s common stock price would lower the market capitalization affecting the fair value of the reporting unit. Additionally, market data used in the future assessment of the implied control premium could change the Company’s current estimate. If actual results are not consistent with the Company’s estimates and assumptions used to calculate fair value, performance of the second step might be required, which could result in a material impairment of goodwill. The closing price of the Company’s stock on September 30, 2014 was $0.95. The closing stock price during October 2014 ranged from $0.72 to $1.10

- Definition

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:

Discontinued Operations and Assets Held For Sale

Note 5. Discontinued Operations and Assets Held For Sale

On December 31, 2013, the Company entered into a definitive asset purchase agreement with InfoMedia for the sale of all assets and the assignment of all agreements related to the Company’s mobile social application business. The closing of the transaction occurred on February 18, 2014 (“Closing”).

Upon Closing, as consideration for the assets and agreements related to the Company’s mobile social application business, the Company received 18 Class B shares of InfoMedia, which represent an 8.25% ownership interest in InfoMedia. Additionally, the Company’s Chief Executive Officer was appointed as a full voting member on InfoMedia’s board of directors and the Company received a number of customary protective rights. The InfoMedia Class B shares were accounted for as a cost-method investment at the carrying amount of $787 and are included in Other assets in the consolidated balance sheet as of September 30, 2014. During the nine month period ended September 30, 2014, there were no events or changes in circumstances that would indicate that the carrying amount of this investment may no longer be recoverable.

In connection with the asset purchase agreement, the requirement to report the results of the Company’s mobile social application business as discontinued operations was triggered. The following tables represent the components of operating results from discontinued operations, as presented in the consolidated statements of operations:

Fair Value Measurements

Fair Value Measurements [Abstract]

Fair Value Measurements

Note 6. Fair Value Measurements

The Company measures fair value in accordance with FASB 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 September 30, 2014 and December 31, 2013:

			Fair value measurement at reporting date using
			Quoted prices in
			active markets		Significant other		Significant
			for identical		observable		unobservable
Derivative warrant liabilities	Balance		assets (Level 1)		inputs (Level 2)		inputs (Level 3)
As of September 30, 2014	$	319		—		—	$	319
As of December 31, 2013	$	4,083		—		—	$	4,083

The Company measures its derivative liabilities at fair value. The Special Bridge Warrants, Conversion Warrants, the derivative Reload Warrants and the derivative Series 1 Warrants (as defined in Note 8) are classified within Level 3 because they are valued using the Black-Scholes-Merton and the Monte-Carlo models (as these warrants include down-round protection clauses), which utilize significant inputs that are unobservable in the market.

The following table presents the placement in the fair value hierarchy of assets that are measured at fair value on a non-recurring basis as of December 31, 2013 (there were no such assets or liabilities as of September 30, 2014):

In addition to the above, the Company’s financial instruments as of September 30, 2014 and December 31, 2013 consisted of cash, cash equivalents, receivables, accounts payable and deposits. The carrying amounts of all the aforementioned financial instruments approximate fair value. The following table summarizes the changes in the Company’s liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) during the nine month period ended September 30, 2014:

	Level 3
Balance at December 31, 2013	$	4,083
Fair value adjustment, prior to exercise of warrants, included in consolidated statement of operations		56
Exercise of derivative warrants		(1,707)
Fair value adjustment at end of period, included in consolidated statement of operations		(2,113)
Balance at September 30, 2014	$	319

Valuation processes for Level 3 Fair Value Measurements

Fair value measurement of the derivative warrant liabilities related to the Special Bridge Warrants, Conversion Warrants, Reload Warrants and Series 1 Warrants (as defined in Note 8) fall 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.

Description	Valuation technique	Unobservable inputs	Range
Special Bridge Warrants, Conversion Warrants, derivative	Black-Scholes-Merton and the	Volatility	58.34% – 92.99%
Reload Warrants and derivative Series 1 Warrants	Monte-Carlo models	Risk free interest rate	0.00% – 0.95%
		Expected term, in years	0.24 – 2.80
		Dividend yield	0%
		Probability and timing of down-round triggering event	5% occurrence in June 2015

The fair value of the assets held for sale as of December 31, 2013 (Note 5) was determined by estimating the present value of the expected future cash flows associated with that asset or asset group by using certain unobservable market inputs. These inputs included discount rates, estimated future cash flows and certain continuing growth rate assumptions. The discount rates are intended to reflect the risk inherent in the projected future cash flows generated by the respective asset or asset group. The inputs used in the valuation were sensitive to certain factors related to mobile social application technology such as rapid changes in the industry and technological advances.

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 are the current market price of the Company’s common stock, the exercise price of the warrant, its remaining expected term, the volatility of the Company’s common stock price, the Company’s assumptions regarding the probability and timing of a down-round protection triggering event and the risk-free interest rate. 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, an increase in the remaining term of the warrant, or an increase of a probability of a down-round triggering event 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 positive differential between the warrant’s exercise price and the market price of the Company’s shares of common stock would result in a decrease in the estimated fair value measurement of the warrants 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 due to the dividend assumption.

- Definition

On June 19, 2014, the Company entered into agreements with certain of its warrant holders, pursuant to which the warrant holders exercised for cash 5,697,227 of their outstanding Series 1 and Series 2 warrants, with an exercise price of $1.76 per share. The Company granted such warrant holders unregistered warrants of the Company to purchase an aggregate of 5,412,366 shares of the Company’s common stock, par value $0.01 per share, at an exercise price of $5.06 per share (the “June 2014 Warrants”). The June 2014 Warrants expire on June 21, 2015 and because such warrants do not bear any down-round protection clauses, they are classified as equity instruments. As a result of these transactions, the Company received $10,027 of proceeds.

The Company’s outstanding warrants consist of the following:

	No. outstanding		No. outstanding classified as equity		No. outstanding classified as liabilities*		Exercise price		Remaining contractual life
Series 1 Warrants		1,490,250		64,621		1,425,629	$	1.76	2.80 years

* These warrants bear down-round protection clauses and as a result, they are classified as derivative liabilities and recorded at fair value.

** The June 2014 Warrants were valued on the grant date (June 20, 2014) using the following assumptions: volatility: 40.05%, stock price: $3.33, risk free interest rate: 0.15% and dividend yield: 0%. The new warrants issued in connection with the exercise of warrants that were classified as liabilities were accounted for as an inducement and therefore an amount of $65, which is based on the fair value of the new warrants, was recorded as a non-operating expense during the second quarter of 2014. The new warrants issued in connection with the exercise of warrants that were classified as equity, which were fair valued at $611, were recorded as equity.

The Company’s subsidiaries have filed patent infringement lawsuits against the subsidiaries of ZTE Corporation and its subsidiaries in the United Kingdom, France, Germany, Australia, India, Brazil, Malaysia, and Romania, and against ASUSTeK Computer, Inc. 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 Corporation and its subsidiaries in various countries. It should be noted, however, that 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.

Pursuant to negotiation with ZTE’s United Kingdom 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. The defendants estimated the total possible liability to be no more than approximately $2,900 for each case. The Company’s best estimate of such possible liability related to the first written commitment is $2,000. The Company believes that payment of such amount is not probable. With respect to the second written commitment, the Company has determined that the possible liability amount is not reasonably estimable and that payment is not probable. In March 2014, the Company withdrew its claim to a certain patent included in the litigation against ZTE’s United Kingdom subsidiary. Consequently, the Company is liable for certain of ZTE's legal fees which will be determined and paid at the end of the case. During the third quarter of 2014, the Company recorded $405, which represents the Company’s best estimate of this liability, in Other liabilities included in the consolidated balance sheet as of September 30, 2014.

On May 5, 2014, the Company deposited a bond of approximately $1,400 to enforce an injunction against ZTE in Germany. 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 approximately $904 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.

The $1,400 bond deposit in Germany and the $904 surety deposit in Brazil are included in Deposits with courts in the consolidated balance sheet as of September 30, 2014.

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. However, 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 when the new office space was available on August 1, 2014. This lease will expire in October 2019. Rent expense for operating leases for the three and nine month periods ended September 30, 2014 were $91 and $273, respectively. Rent expense for operating leases for the three and nine month periods ended September 30, 2013 were $68 and $175, respectively.

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, on September 30, 2014, the Patent Re-Examination Board of the State Intellectual Property Office of the People’s Republic of China held that one of the Company's Chinese patents is invalid. The Company is appealing this decision. 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 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.

Subsequent Events

Note 12. Subsequent Events

On October 24, 2014, the President of the District Court of The Hague (“the Court”) in the Netherlands denied ZTE’s requests to seek the release of ZTE UMTS products being held by Dutch customs officials and to order the Company to ask the Dutch customs authorities to stop their actions against ZTE’s products based on the Anti-Piracy Regulations of the European Union. Further, the Court upheld the detention of ZTE’s goods, finding, prima facie, that ZTE has infringed one of Vringo’s European patents, upholding the validity of that patent, and rejecting ZTE’s argument that the Company has violated European competition law by enforcing that patent. ZTE was also ordered to pay Vringo’s legal costs of approximately $250,000. ZTE may choose to appeal this decision.

* These warrants bear down-round protection clauses and as a result, they are classified as derivative liabilities and recorded at fair value.

- 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.

These warrants bear down-round protection clauses and as a result, they are classified as derivative liabilities and recorded at fair value.

The June 2014 Warrants were valued on the grant date (June 20, 2014) using the following assumptions: volatility: 40.05%, stock price: $3.33, risk free interest rate: 0.15% and dividend yield: 0%. The new warrants issued in connection with the exercise of warrants that were classified as liabilities were accounted for as an inducement and therefore an amount of $65, which is based on the fair value of the new warrants, was recorded as a non-operating expense during the second quarter of 2014. The new warrants issued in connection with the exercise of warrants that were classified as equity, which were fair valued at $611, were recorded as equity.
