NATURE OF OPERATIONS	'
	NATURE OF OPERATIONS
	TiVo Inc. (together with its subsidiaries the "Company” or “TiVo”) was incorporated in August 1997 as a Delaware corporation and is located in San Jose, California. The unaudited interim condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All inter-company accounts and transactions have been eliminated in consolidation. The Company conducts its operations through one reportable segment.
	The Company is subject to a number of risks, including delays in product and service developments; competitive product and service offerings; lack of market acceptance; uncertainty of future profitability; the dependence on third parties for manufacturing, marketing, and sales support, as well as third-party rollout schedules, software development issues for third-party products which contain its technology; access to television programming including digital cable signals in connection with CableCARD and switched digital Internet Protocol, downloadable conditional access, and other new signal delivery and encryption technologies; dependence on its relationships with third-party service providers for subscription growth; and the Company’s ability to sustain and grow both its TiVo-Owned and MSO subscription base. The Company anticipates that its retail business will continue to be seasonal and expects to generate a significant portion of its new subscriptions during and immediately after the holiday shopping season. The Company remains cautious about its ability to grow or even slow the decline in its TiVo-Owned subscription base.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	'
	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Basis of Presentation
	The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles (“GAAP”) for interim financial information, the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, the unaudited interim condensed consolidated financial statements do not contain all of the information and footnotes required by generally accepted accounting principles for complete audited annual financial statements. In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all adjustments, consisting of normal recurring adjustments, necessary for the fair presentation of the Company’s financial position as of October 31, 2013 and January 31, 2013 and the results of operations and the statement of other comprehensive income for the three and nine months ended October 31, 2013 and 2012 and condensed consolidated statements of cash flows for the nine month periods ended October 31, 2013 and 2012. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements, including the notes thereto, included in the Company’s annual report on Form 10-K for the fiscal year ended January 31, 2013. Operating results for the three and nine month periods ended October 31, 2013 are not necessarily indicative of results that may be expected for this fiscal year ending January 31, 2014 or any other periods.
	Deferred Tax Assets
	We make certain estimates in determining income tax expense for financial statement purposes. These estimates occur in the calculation of certain tax assets and liabilities, which arise from differences in the timing of recognition of revenue and expense for tax and financial statement purposes. From time-to-time, we evaluate the expected realization of our deferred tax assets and determine whether a valuation allowance needs to be established or released. In determining the need for and amount of our valuation allowance, we assess the likelihood that we will be able to recover our deferred tax assets using historical levels of income and estimates of future income. Our estimates of future income include our internal projections and various internal estimates and certain external sources which we believe to be reasonable but that are unpredictable and inherently uncertain. We also consider the jurisdictional mix of income and loss, changes in tax regulations in the period the changes are enacted and the type of deferred tax assets and liabilities. In assessing whether a valuation allowance needs to be established or released, we use judgment in considering the cumulative effect of negative and positive evidence and the weight given to the potential effect of the evidence. Recent historical income or loss and future projected operational results have the most influence on our determinations of whether a deferred tax valuation allowance is required or not.
	Our other critical accounting policies or in the matters for which we make critical accounting estimates in the preparation of our condensed consolidated financial statements are set out under the heading "Critical Accounting Estimates" in our Annual Report on Form 10-K for the fiscal year ended January 31, 2013.
	Recent Accounting Pronouncements
	In June 2013, the Financial Accounting Standards Board ratified Emerging Issues Task Force (EITF) Issue 13-C, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists” which concludes an unrecognized tax benefit should be presented as a reduction of a deferred tax asset when settlement in this manner is available under the tax law. The Company will adopt this amendment as of the fiscal quarter ending April 30, 2014. The Company does not believe that the impact of adopting this amendment will be significant on the Company's results of operations and financial condition.

Fair Value Disclosures [Abstract]	'
FAIR VALUE	'
	FAIR VALUE
	Inputs to valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect TiVo's market assumptions. These two types of inputs have created the following fair-value hierarchy:
	Level 1 - Quoted prices for identical instruments in active markets;
	Level 2 - Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and
	Level 3 - Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.
	This hierarchy requires TiVo to minimize the use of unobservable inputs and to use observable market data, if available, when determining fair value. TiVo recognizes transfers between levels of the hierarchy based on the fair values of the respective financial instruments at the end of the reporting period in which the transfer occurred.
	Cash equivalents and available-for-sale marketable securities (including asset- and mortgage-backed securities) are reported at their fair value. Additionally, carrying amounts of certain of the Company’s financial instruments including accounts receivable, accounts payable, and accrued expenses approximate their fair value because of their short maturities. The Company has financial liabilities for which it is obligated to repay the carry value, unless the holder agrees to a lesser amount. These financial liabilities include TiVo's convertible debt. The fair values of TiVo's convertible debt are influenced by interest rates, TiVo's stock price and stock price volatility and are determined by Level 2 inputs, including prices for the convertible debt observed in market trading. The carrying value of these financial liabilities at October 31, 2013 and January 31, 2013 was $172.5 million (for both periods) and the fair value was $238.1 million and $241.6 million, based on the bonds' quoted market price as of October 31, 2013 and January 31, 2013, respectively.
	On a quarterly basis, TiVo measures at fair value certain financial assets and liabilities. The fair value of those financial assets and liabilities was determined using the following levels of inputs as of October 31, 2013 and January 31, 2013:
		As of October 31, 2013

	Level 1 Measurements
	TiVo's cash equivalents held in money market funds, TiVo's available-for-sale securities and the trading securities are measured at fair value using Level 1 inputs.
	Level 2 Measurements
	The Company uses inputs such as broker/dealer quotes, and other similar data, which are obtained from quoted market prices, independent pricing vendors, or other sources, to determine the ultimate fair value of these assets and liabilities. The Company uses such pricing data as the primary input to make its assessments and determinations as to the ultimate valuation of its investment portfolio and has not made, during the periods presented, any material adjustments to such inputs. The Company is ultimately responsible for the financial statements and underlying estimates.
	Level 3 Measurements
	As of October 31, 2013, TiVo had no Level 3 instruments.
	The Company did not have any transfers between Level 1, Level 2, and Level 3 fair value measurements during the periods presented as there were no changes in the composition of Level 1, 2, or 3 securities.
	TiVo also has a direct investment in a privately-held company accounted for under the cost method, which is periodically assessed for other-than-temporary impairment. If the Company determines that an other-than-temporary impairment has occurred, TiVo will write-down the investment to its fair value. The fair value of a cost method investment is not evaluated if there are no identified events or changes in circumstances that may have asignificant adverse effect on the fair value of the investment. However, if such a significant adverse events were identified, the Company would estimate the fair value of its cost method investment considering available information at the time of the event, such as pricing in recent rounds of financing, current cash position, earnings and cash flow forecasts, recent operational performance, and any other readily available data. The carrying amount of the Company's cost method investment was $250,000 as of October 31, 2013. No events or circumstances indicating a potential impairment were identified as of October 31, 2013.

	Product Warranties
	The Company’s standard manufacturer's warranty period to consumers for TiVo-enabled DVRs is 90 days for parts and labor from the date of consumer purchase, and from 91-365 days for parts only. Within the limited warranty period, consumers are offered a no-charge exchange for TiVo-enabled DVRs returned due to product defect, within 90 days from the date of consumer purchase. Thereafter, consumers may exchange a TiVo-enabled DVR with a product defect for a charge. As of October 31, 2013 and January 31, 2013, the accrued warranty reserve was $534,000 and $419,000, respectively. The Company’s accrued warranty reserve is included in accrued liabilities in the accompanying condensed consolidated balance sheets.
	The Company also offers its TiVo-Owned customers separately priced optional 2-year and 3-year extended warranties. The Company defers and amortizes cost and revenue associated with the sales of these extended warranties over the warranty period or until a warranty is redeemed. Additionally the Company offers its MSO customers separately priced optional 3-year extended warranties. The Company defers the revenues associated with sale of these extended warranties over the second and third year of the warranty period. As of October 31, 2013, the extended warranty deferred revenue and cost was $1,898,000 and $258,000, respectively. As of January 31, 2013, the extended warranty deferred revenue and cost was $875,000 and $269,000, respectively.
	Indemnification Arrangements
	The Company undertakes indemnification obligations in its ordinary course of business. For instance, the Company has undertaken to indemnify its underwriters and certain investors in connection with the issuance and sale of its securities and the Company provides indemnification for its directors and officers in accordance with Delaware law. The Company has also undertaken to indemnify certain customers and business partners for, among other things, the licensing of its products, the sale of its DVRs, and the provision of engineering and consulting services. Pursuant to these agreements, the Company may indemnify the other party for certain losses suffered or incurred by the indemnified party in connection with various types of claims, which may include, without limitation, intellectual property infringement, advertising and consumer disclosure laws, certain tax liabilities, negligence and intentional acts in the performance of services and violations of laws, including certain violations of securities laws with respect to underwriters and investors. The term of these indemnification obligations is generally perpetual. The Company’s obligation to provide indemnification under its agreements with customer and business partners would arise in the event that a third party filed a claim against one of the parties that was covered by the Company’s indemnification obligation. As an example, if a third party sued a customer for intellectual property infringement and the Company agreed to indemnify that customer against such claims, its obligation would be triggered.
	The Company is unable to estimate with any reasonable accuracy the liability that may be incurred pursuant to its indemnification obligations, if any. Variables affecting any such assessment include but are not limited to: the nature of the claim asserted; the relative merits of the claim; the financial ability of the party suing the indemnified party to engage in protracted litigation; the number of parties seeking indemnification; the nature and amount of damages claimed by the party suing the indemnified party; and the willingness of such party to engage in settlement negotiations. Due to the nature of the Company’s potential indemnity liability, its indemnification obligations could range from immaterial to having a material adverse impact on its financial position and its ability to continue operation in the ordinary course of business.
	Under certain circumstances, the Company may have recourse through its insurance policies that would enable it to recover from its insurance company some or all amounts paid pursuant to its indemnification obligations. The Company does not have any assets held either as collateral or by third parties that, upon the occurrence of an event requiring it to indemnify a customer, the Company could obtain and liquidate to recover all or a portion of the amounts paid pursuant to its indemnification obligations.
	Legal Matters
	Intellectual Property Litigation.
	On October 6, 2011, Digital CBT filed a complaint against TiVo in the District of Delaware (“First Action”) alleging infringement of U.S. Patent No. 5,805,173 ("System and Method for Capturing and Transferring Selected Portions of a Video Stream in a Computer System"). Digital CBT sought an injunction and unspecified damages. On March 22, 2012, Digital CBT dismissed the Delaware complaint and filed a substantially identical complaint in the Central District of California (“Second Action”). On July 18, 2012, Digital CBT informed the Company of a potential standing issue with the March 22, 2012 complaint because it appeared that Digital CBT did not have the necessary rights to assert infringement of the '173 patent against the Company. On July 24, 2012, the Company filed a complaint against Digital CBT in the Northern District of California (“Third Action”) requesting declaratory judgment that U.S. Patent No. 5,805,173 ("System and Method for Capturing and Transferring Selected Portions of a Video Stream in a Computer System") is invalid and not infringed. On July 26, 2012, Digital CBT claimed to have corrected its standing problem and filed a complaint against TiVo (“Fourth Action”), substantially identical to its March 22, 2012 complaint against the Company, in the Central District of California. On July 30, 2012, Digital CBT filed a motion to dismiss its own Second Action, which TiVo did not oppose, and on August 29, 2012 the court dismissed the Second Action. On September 17, 2012, Digital CBT filed a motion to dismiss or alternatively to transfer the Third Action to the Central District of California. On October 29, 2012, the Court transferred the Third Action to the Central District of California, where the Fourth Action is pending and where Digital CBT has a case involving the same patent pending against AT&T. On October 31, 2012 TiVo filed its answer and counterclaims in the Fourth Action. On April 5, 2013, the United States District Court for the Central District of California Southern Division entered an order in the Digital CBT v. TiVo case scheduling, among other things, the completion of discovery by April 18, 2014 and jury trial to begin on July 29, 2014. The Company may incur material expenses in connection with these litigations and in the event there is an adverse outcome, the Company's business could be harmed. The Company has determined a potential loss is reasonably possible; however, based on its current knowledge, management does not believe that the amount of such possible loss or a range of potential loss is reasonably estimable.
	From time to time, the Company is involved in numerous lawsuits as well as subject to various legal proceedings, claims, threats of litigation, and investigations in the ordinary course of business, including claims of alleged infringement of third-party patents and other intellectual property rights, commercial, employment and other matters. The Company assesses potential liabilities in connection with each lawsuit and threatened lawsuits and accrues an estimated loss for these loss contingencies if both of the following conditions are met: information available prior to issuance of the financial statements indicates that it is probable that a liability has been incurred at the date of the financial statements and the amount of loss can be reasonably estimated. While certain matters to which the Company is a party specify the damages claimed, such claims may not represent reasonably possible losses. Given the inherent uncertainties of the litigation, the ultimate outcome of these matters cannot be predicted at this time, nor can the amount of possible loss or range of loss, if any, be reasonably estimated. As of October 31, 2013, the Company has not accrued any pre-judgment liability for any lawsuits filed against the Company, as the Company has neither determined that it is probable that a liability has been incurred at the date of the financial statements nor that the amount of any loss can be reasonably estimated. The Company has accrued $4.5 million, including accrued interest, for arbitrations proceedings related to a contractual dispute. The Company is currently appealing an unfavorable decision in the initial arbitration proceeding. The Company expenses legal costs as they are incurred.

NET INCOME PER COMMON SHARE	'
	NET INCOME PER COMMON SHARE
	Basic net income per common share is computed by dividing net income by the weighted average number of common shares outstanding, excluding unvested restricted stock.
	Diluted net income per common share is computed based on the weighted average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period. Dilutive potential common shares include outstanding stock options, stock awards, and performance stock awards and are calculated using the treasury stock method. Also included in the weighted average effect of dilutive securities is the diluted effect of the convertible senior notes which is calculated using the if-converted method.
	The following table sets forth the computation of basic and diluted earnings per common share:

SETTLEMENTS	'
	SETTLEMENTS
	Effective July 2, 2013, TiVo entered into a settlement and patent license agreement (the “Settlement Agreement”) with ARRIS Group, Inc. (“Arris”) (owner of General Instrument Corporation, formerly a subsidiary of Motorola Mobility, Inc.), Cisco Systems, Inc. (“Cisco”), and Google Inc. (“Google”) (owner of Motorola Mobility, LLC formerly Motorola Mobility, Inc.), pursuant to which the parties agreed to settle and dismiss all outstanding litigation between them, including Time Warner Cable (as described in TiVo's periodic reports filed with the Securities and Exchange Commission ), provide licenses to certain patents between the parties, and release patent infringement claims between the parties with respect to all outstanding litigation in exchange for a payment of $490.0 million to TiVo by Google/Motorola Mobility and Cisco.
	The licenses granted by TiVo to Cisco and Google/Motorola Mobility under U.S. Patent Nos. 6,233,389, 7,529,465, 6,792,195, and 7,493,015 (the “TiVo patents-in-suit”) and certain related patents are perpetual. The other licenses granted by TiVo to Google/Motorola Mobility and from Google/Motorola Mobility to TiVo will expire on July 31, 2018. The other licenses granted by TiVo to Cisco and from Cisco to TiVo will expire on July 2, 2023, when the agreement expires.
	The agreement includes multiple elements consisting of: (i) an exchange of licenses to certain intellectual property, (ii) an interest income component related to the past infringement, and (iii) the settlement of all outstanding litigation and claims between TiVo and Arris, Google/Motorola Mobility and Cisco. The proceeds of the agreement were allocated amongst the principal elements of the transaction based on relative fair values of each element.
	TiVo estimated the fair value of future licensing revenue from July 2, 2013 until July 31, 2018 using an income approach and future licensing revenue from August 1, 2018 to July 2, 2023 using a market approach. The significant inputs and assumptions used in the valuations included actual past and projected future estimated infringing DVR shipments, estimated life of the DVR, estimated market-based royalty rates, and estimated risk-adjusted discount rates, among others. The development of a number of these inputs and assumptions in the model requires a significant amount of management judgment and is based upon a number of factors. Changes in these assumptions may have a substantial impact on the fair value assigned to each element. These inputs and assumptions represent management's best estimates at the time of the transaction.
	The total consideration of $490.0 million was allocated on a relative fair value basis as $381.1 million to the future licensing revenue element, $752,000 to interest income related to past infringement and $108.1 million to the past infringement and litigation settlement element. The amount related to past infringement and settlement was recorded under “Litigation proceeds” in the nine months ended October 31, 2013. The amount related to interest income was recorded under “Interest income” in the nine months ended October 31, 2013. $381.1 million of license royalties has been or will be recorded as technology revenues over the term of the agreement through July 2023.
	Licensing revenues have been or are expected to be recognized as follows (in thousands):

	On September 21, 2012, TiVo Inc. entered into a Settlement and Patent License Agreement with Verizon Communications, Inc. ("VZ"). Under the terms of the Agreement, VZ agreed to pay TiVo a minimum amount of $250.4 million plus incremental monthly fees per DVR subscriber if VZ's subscriber base exceeds certain pre-determined levels which increase annually.
	The total consideration of $250.4 million was allocated on a relative fair value basis as $78.4 million to the past infringement and litigation settlement element, $568,000 to interest income related to past infringement and $171.4 million to the base license royalties element that has been or will be recognized in the future. The amount related to past infringement and settlement was recorded under “Litigation proceeds” in the three and nine months ended October 31, 2012. The amount related to interest income was recorded under “Interest income” in the three and nine months ended October 31, 2012.

INCOME TAX	'
	INCOME TAX
	The Company recorded income tax benefit for the three and nine months ended October 31, 2013 of ($2.0) million and ($168.9) million, respectively.
	The Company had a deferred tax asset of $220.5 million as of January 31, 2013, which has been previously reduced by a full valuation allowance. After evaluating positive and negative evidence available as of October 31, 2013, the Company has determined that it is more likely than not that it will realize its deferred tax assets for federal tax purposes and all state taxes except for the state of California. The Company now has three years of cumulative income and is also forecasting future taxable income due primarily to the settlement agreements (described in Note 9 "Settlements" above) entered into during the nine months ended October 31, 2013.
	As a result, the Company has recognized a net deferred tax asset of approximately $171.8 million on its condensed consolidated balance sheet as of October 31, 2013.
	The Company continues to conclude that it does not meet the more likely than not criteria for its California deferred tax assets as of October 31, 2013 because the income attributable to California is not expected to be sufficient to realize these deferred tax assets.

Accordingly, the unaudited interim condensed consolidated financial statements do not contain all of the information and footnotes required by generally accepted accounting principles for complete audited annual financial statements. In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all adjustments, consisting of normal recurring adjustments, necessary for the fair presentation of the Company’s financial position as of October 31, 2013 and January 31, 2013 and the results of operations and the statement of other comprehensive income for the three and nine months ended October 31, 2013 and 2012 and condensed consolidated statements of cash flows for the nine month periods ended October 31, 2013 and 2012. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements, including the notes thereto, included in the Company’s annual report on Form 10-K for the fiscal year ended January 31, 2013. Operating results for the three and nine month periods ended October 31, 2013 are not necessarily indicative of results that may be expected for this fiscal year ending January 31, 2014 or any other periods.
Deferred Tax Assets	'
	Deferred Tax Assets
	We make certain estimates in determining income tax expense for financial statement purposes. These estimates occur in the calculation of certain tax assets and liabilities, which arise from differences in the timing of recognition of revenue and expense for tax and financial statement purposes. From time-to-time, we evaluate the expected realization of our deferred tax assets and determine whether a valuation allowance needs to be established or released. In determining the need for and amount of our valuation allowance, we assess the likelihood that we will be able to recover our deferred tax assets using historical levels of income and estimates of future income. Our estimates of future income include our internal projections and various internal estimates and certain external sources which we believe to be reasonable but that are unpredictable and inherently uncertain. We also consider the jurisdictional mix of income and loss, changes in tax regulations in the period the changes are enacted and the type of deferred tax assets and liabilities. In assessing whether a valuation allowance needs to be established or released, we use judgment in considering the cumulative effect of negative and positive evidence and the weight given to the potential effect of the evidence. Recent historical income or loss and future projected operational results have the most influence on our determinations of whether a deferred tax valuation allowance is required or not.
	Our other critical accounting policies or in the matters for which we make critical accounting estimates in the preparation of our condensed consolidated financial statements are set out under the heading "Critical Accounting Estimates" in our Annual Report on Form 10-K for the fiscal year ended January 31, 2013.

The Company will adopt this amendment as of the fiscal quarter ending April 30, 2014. The Company does not believe that the impact of adopting this amendment will be significant on the Company's results of operations and financial condition.

	The Company also offers its TiVo-Owned customers separately priced optional 2-year and 3-year extended warranties. The Company defers and amortizes cost and revenue associated with the sales of these extended warranties over the warranty period or until a warranty is redeemed. Additionally the Company offers its MSO customers separately priced optional 3-year extended warranties. The Company defers the revenues associated with sale of these extended warranties over the second and third year of the warranty period. As of October 31, 2013, the extended warranty deferred revenue and cost was $1,898,000 and $258,000, respectively. As of January 31, 2013, the extended warranty deferred revenue and cost was $875,000 and $269,000, respectively.
	Indemnification Arrangements
	The Company undertakes indemnification obligations in its ordinary course of business. For instance, the Company has undertaken to indemnify its underwriters and certain investors in connection with the issuance and sale of its securities and the Company provides indemnification for its directors and officers in accordance with Delaware law. The Company has also undertaken to indemnify certain customers and business partners for, among other things, the licensing of its products, the sale of its DVRs, and the provision of engineering and consulting services. Pursuant to these agreements, the Company may indemnify the other party for certain losses suffered or incurred by the indemnified party in connection with various types of claims, which may include, without limitation, intellectual property infringement, advertising and consumer disclosure laws, certain tax liabilities, negligence and intentional acts in the performance of services and violations of laws, including certain violations of securities laws with respect to underwriters and investors. The term of these indemnification obligations is generally perpetual. The Company’s obligation to provide indemnification under its agreements with customer and business partners would arise in the event that a third party filed a claim against one of the parties that was covered by the Company’s indemnification obligation. As an example, if a third party sued a customer for intellectual property infringement and the Company agreed to indemnify that customer against such claims, its obligation would be triggered.
	The Company is unable to estimate with any reasonable accuracy the liability that may be incurred pursuant to its indemnification obligations, if any. Variables affecting any such assessment include but are not limited to: the nature of the claim asserted; the relative merits of the claim; the financial ability of the party suing the indemnified party to engage in protracted litigation; the number of parties seeking indemnification; the nature and amount of damages claimed by the party suing the indemnified party; and the willingness of such party to engage in settlement negotiations. Due to the nature of the Company’s potential indemnity liability, its indemnification obligations could range from immaterial to having a material adverse impact on its financial position and its ability to continue operation in the ordinary course of business.
	Under certain circumstances, the Company may have recourse through its insurance policies that would enable it to recover from its insurance company some or all amounts paid pursuant to its indemnification obligations. The Company does not have any assets held either as collateral or by third parties that, upon the occurrence of an event requiring it to indemnify a customer, the Company could obtain and liquidate to recover all or a portion of the amounts paid pursuant to its indemnification obligations.
	Legal Matters
	Intellectual Property Litigation.
	On October 6, 2011, Digital CBT filed a complaint against TiVo in the District of Delaware (“First Action”) alleging infringement of U.S. Patent No. 5,805,173 ("System and Method for Capturing and Transferring Selected Portions of a Video Stream in a Computer System"). Digital CBT sought an injunction and unspecified damages. On March 22, 2012, Digital CBT dismissed the Delaware complaint and filed a substantially identical complaint in the Central District of California (“Second Action”). On July 18, 2012, Digital CBT informed the Company of a potential standing issue with the March 22, 2012 complaint because it appeared that Digital CBT did not have the necessary rights to assert infringement of the '173 patent against the Company. On July 24, 2012, the Company filed a complaint against Digital CBT in the Northern District of California (“Third Action”) requesting declaratory judgment that U.S. Patent No. 5,805,173 ("System and Method for Capturing and Transferring Selected Portions of a Video Stream in a Computer System") is invalid and not infringed. On July 26, 2012, Digital CBT claimed to have corrected its standing problem and filed a complaint against TiVo (“Fourth Action”), substantially identical to its March 22, 2012 complaint against the Company, in the Central District of California. On July 30, 2012, Digital CBT filed a motion to dismiss its own Second Action, which TiVo did not oppose, and on August 29, 2012 the court dismissed the Second Action. On September 17, 2012, Digital CBT filed a motion to dismiss or alternatively to transfer the Third Action to the Central District of California. On October 29, 2012, the Court transferred the Third Action to the Central District of California, where the Fourth Action is pending and where Digital CBT has a case involving the same patent pending against AT&T. On October 31, 2012 TiVo filed its answer and counterclaims in the Fourth Action. On April 5, 2013, the United States District Court for the Central District of California Southern Division entered an order in the Digital CBT v. TiVo case scheduling, among other things, the completion of discovery by April 18, 2014 and jury trial to begin on July 29, 2014. The Company may incur material expenses in connection with these litigations and in the event there is an adverse outcome, the Company's business could be harmed. The Company has determined a potential loss is reasonably possible; however, based on its current knowledge, management does not believe that the amount of such possible loss or a range of potential loss is reasonably estimable.
	From time to time, the Company is involved in numerous lawsuits as well as subject to various legal proceedings, claims, threats of litigation, and investigations in the ordinary course of business, including claims of alleged infringement of third-party patents and other intellectual property rights, commercial, employment and other matters. The Company assesses potential liabilities in connection with each lawsuit and threatened lawsuits and accrues an estimated loss for these loss contingencies if both of the following conditions are met: information available prior to issuance of the financial statements indicates that it is probable that a liability has been incurred at the date of the financial statements and the amount of loss can be reasonably estimated. While certain matters to which the Company is a party specify the damages claimed, such claims may not represent reasonably possible losses. Given the inherent uncertainties of the litigation, the ultimate outcome of these matters cannot be predicted at this time, nor can the amount of possible loss or range of loss, if any, be reasonably estimated. As of October 31, 2013, the Company has not accrued any pre-judgment liability for any lawsuits filed against the Company, as the Company has neither determined that it is probable that a liability has been incurred at the date of the financial statements nor that the amount of any loss can be reasonably estimated. The Company has accrued $4.5 million, including accrued interest, for arbitrations proceedings related to a contractual dispute. The Company is currently appealing an unfavorable decision in the initial arbitration proceeding. The Company expenses legal costs as they are incurred.
