Organization Consolidation And Presentation Of Financial Statements [Abstract]
The Company and Basis of Presentation	NOTE 1 – THE COMPANY AND BASIS OF PRESENTATION Xperi Corporation (the “Company”) licenses its innovative products, technologies and inventions to global electronics companies which, in turn, integrate the technologies into their own consumer electronics and semiconductor products. The Company’s technologies and inventions are widely adopted and used every day by millions of people. The Company’s audio technologies have shipped in billions of devices for the home, mobile and automotive markets. The Company's imaging technologies have been embedded in billions of smartphones and other mobile devices. The Company's semiconductor packaging and interconnect technologies have been licensed to more than 100 customers and have shipped in over 100 billion semiconductor chips. The accompanying interim unaudited condensed consolidated financial statements as of March 31, 2020 and 2019, and for the three months then ended, have been prepared by the Company in accordance with generally accepted accounting principles (“GAAP”) in the United States (“U.S.”) for interim financial information. The amounts as of December 31, 2019 have been derived from the Company’s annual audited financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted in accordance with such rules and regulations. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments necessary (consisting of normal recurring adjustments) to state fairly the financial position of the Company and its results of operations and cash flows as of and for the periods presented. These financial statements should be read in conjunction with the annual audited financial statements and notes thereto as of and for the year ended December 31, 2019, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, filed on February 18, 2020 (the “Form 10-K”). The results of operations for the three months ended March 31, 2020 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2020 or any future period and the Company makes no representations related thereto. In the fourth quarter of 2018, the Company funded a new subsidiary, Perceive Corporation (“Perceive”), which was created to focus on delivering edge inference solutions. As a result of issuing new shares in Perceive to noncontrolling interests, the Company’s ownership interest in Perceive decreased to approximately 83% as of March 31, 2020. The operating results of Perceive have been consolidated in the Company’s condensed consolidated financial statements for all periods presented. In the first quarter of 2019, the Company recorded an out-of-period adjustment to decrease current unbilled receivables and decrease retained earnings by Accounting Standards Update (“ASU”) No . 2014-09 (Topic 606) “Revenue from Contracts with Customers.” On December 18, 2019, the Company entered into an Agreement and Plan of Merger and Reorganization (as amended on January 31, 2020, the “Merger Agreement”) with TiVo Corporation (“TiVo”) to combine in an all-stock merger of equals transaction (the “Mergers”). The Mergers are expected to close and become effective (the “Effective Time”) during the second quarter of 2020, subject to regulatory approvals, the approval by the shareholders of each company, and other customary closing conditions. Subject to the terms and conditions of the Merger Agreement, each share of Company common stock (“Xperi Common Stock”) issued and outstanding immediately prior to the Effective Time, excluding any shares of Xperi Common Stock that are held in treasury, will be converted into the right to receive one share of common stock of the combined company and each share of TiVo common stock (“TiVo Common Stock”) issued and outstanding immediately prior to the Effective Time, excluding any shares of TiVo Common Stock that are held in treasury, will be converted into the right to receive 0.455 shares of common stock of the combined company. On a pro forma, fully diluted basis, it is expected that immediately following the Effective Time, Xperi stockholders will own approximately 46.5% of the combined company and TiVo stockholders will own approximately 53.5% of the combined company. In connection with the Merger Agreement, the Company and TiVo obtained a debt commitment letter from Bank of America, N.A., Royal Bank of Canada, and Barclays Bank PLC to provide a senior secured first lien term loan B facility in an aggregate principal amount of $ 1,100 million (the “Debt Financing”), subject to the terms and conditions set forth therein. The proceeds from the Debt Financing may be used (i) to pay fees and expenses incurred in connection with the Mergers and the related transactions, (ii) to accomplish the refinancing of existing indebtedness of the Company and TiVo, and (iii) to the extent of any remaining amounts, for working capital and other general corporate purposes. Reclassification Certain reclassifications have been made to prior period balances in order to conform to the current period’s presentation.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE 2 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Except as noted below, there have been no significant changes in the Company’s significant accounting policies during the three months ended March 31, 2020, as compared to the significant accounting policies described in the Form 10-K . Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. The accounting estimates and assumptions that require management’s most significant, difficult, and subjective judgment include the estimation of licensees’ quarterly royalties prior to receiving the royalty reports, the collectability of accounts receivable, the fair value measurements of goodwill, other intangible assets and investments, the assessment of the recoverability of goodwill, the assessment of useful lives and recoverability of other intangible assets and long-lived assets, recognition and measurement of current and deferred income tax assets and liabilities, the assessment of unrecognized tax benefits and the valuation and recognition of stock-based compensation expense, and business combinations, among others. Actual results experienced by the Company may differ from management’s estimates. The worldwide spread of the COVID-19 virus is expected to result in a global slowdown of economic activity which is likely to decrease demand for a broad variety of goods and services, while also disrupting sales channels, marketing activities and supply chains for an unknown period of time until the disease is contained. The Company expects this to have a negative impact on its revenue, billings and results of operations, the size and duration of which it is currently unable to predict. The Company anticipates that the impact of the COVID-19 virus will increase volatility and make the estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes more difficult, however, as of the date of issuance of the financial statements, the Company is not aware of any specific event or circumstance that would require it to update its estimates, judgments or revise the carrying value of its assets or liabilities. These estimates may change, as new events occur and additional information is obtained, and are recognized in the consolidated financial statements as soon as they become known. Recently Adopted Accounting Pronouncements In September 2016, the Financial Accounting Standards Board (“FASB”) issued Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments Revenue Recent Accounting Pronouncements On December 18, 2019, FASB released ASU 2019-12, “ Simplifying the Accounting for Income Taxes ASU 2019-12 is effective for the Company in the first quarter of the year ending December 31, 2021. The Company is in the process of evaluating the impact of the adoption of this new standard on its consolidated financial statements.

Revenue

Revenue From Contract With Customer [Abstract]
Revenue	NOTE 3 – REVENUE Revenue Recognition The Company derives its revenue primarily from royalty and license fees for rights to use the Company’s intellectual property and technologies (“IP”). Revenue is recognized upon transfer of control of promised products, services or IP rights to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products, services or licensing of the IP rights. Certain licensees have entered into fixed fee or minimum guarantee arrangements, whereby licensees pay a fixed fee for the right to incorporate the Company’s technology in the licensee's products over the license term. In arrangements with a minimum guarantee, the fixed fee component corresponds to a minimum number of units or dollars that the customer must produce or pay, with additional per-unit fees for any units or dollars exceeding the minimum. In most cases, the customer pays the fixed license fee in specified installments over the license term. For both fixed fee and minimum guarantee agreements, the Company recognizes the full fixed fee as revenue at the beginning of the license term, when the licensee has the right to use the IP and begins to benefit from the license. If the contract term of a fixed fee or minimum guarantee arrangement is longer than one year, the Company also considers the scheduled payment arrangements to determine whether a significant financing component exists. In general, if the payment arrangements extend beyond the initial twelve months of the contract, the Company treats a portion of the payments as a significant financing component. When the payments are expected to be received within one year or less, the Company does not adjust the promised amount of consideration for the effects of a financing component. The discount rate used for each arrangement reflects the rate that would be used in a separate financing transaction between the Company and the licensee at contract inception and takes into account the credit characteristics of the licensee and market interest rates as of the date of the agreement. As such, the amount of fixed fee revenue recognized at the beginning of the license term will be reduced by the calculated financing component. As payments are received from the licensee, the Company recognizes a portion of the financing component as interest income, reported as other income and expense in the Condensed Consolidated Statements of Operations. For certain licensees, royalty revenues are generated based on a licensee’s production or shipment of licensed products incorporating the Company’s IP, technologies or software. Licensees with a per-unit arrangement pay a per-unit royalty for each product manufactured or sold, as set forth in its license agreement. Licensees generally report manufacturing or sales information in the quarter subsequent to when the production or shipment activity takes place. The Company estimates the royalties earned each quarter based on its forecast of manufacturing and sales activity incurred by its licensees in that quarter. Any differences between actual royalties owed by a licensee and the Company’s quarterly estimate are recognized in the following quarter, when the licensee’s royalty report is received. Estimating licensees’ quarterly royalties prior to receiving the royalty reports requires the Company to make significant assumptions and judgments related to forecasted trends and growth rates used to estimate quantities shipped by customers, which could have a material impact on the amount of revenue it reports on a quarterly basis. The Company actively monitors and enforces its IP, including seeking appropriate compensation from customers that have under-reported royalties owed under a license agreement and from third parties that utilize the Company’s intellectual property without a license. As a result of these activities, the Company may, from time to time, recognize revenue from payments resulting from periodic compliance audits of licensees for underreporting royalties incurred in prior periods, as part of a settlement of a patent infringement dispute, or from legal judgments in a license dispute. These recoveries and settlements may cause revenue to be higher than expected during a particular reporting period and such recoveries may not occur in subsequent periods. The Company recognizes revenue from recoveries when a binding agreement has been executed and the Company concludes collection under that agreement is likely. In some instances, the Company may enter into license agreements containing multiple performance obligations that include engineering services in addition to a technology or software license. For such arrangements where all components are capable of being distinct and accounted for as separate performance obligations, the Company allocates revenue to each performance obligation based on its relative standalone selling price. The Company generally determines standalone selling prices based on the prices ordinarily charged to customers, or in some cases by applying a reasonable cost-plus margin. The consideration for engineering services is recognized as the underlying performance obligations are satisfied. Generally, the Company satisfies performance obligations over time and therefore recognizes revenue over time by measuring the progress toward completion of the performance obligation at each reporting period. From time to time, the Company enters into arrangements with licensees in which the Company pays consideration to the licensee. Such payments can take the form of marketing development funds or various rebate incentives. The Company typically accounts for consideration paid to its licensees as a reduction to the transaction price and revenue, unless the payment to the licensee is in exchange for a distinct good or service that the licensee transfers to the Company. In cases where the consideration paid to the licensee is variable, the Company estimates the variable consideration based on the terms of the arrangement and expectations of future outcomes. The Company recognizes the reduction to revenue when it recognizes revenue for transfer of control of promised products, services or IP rights to the licensee. Revenue is recognized gross of withholding taxes that are remitted directly by the Company’s licensees to a local tax authority. For additional detail on the Company's revenue disaggregated by geographic location, refer to Note 15 – “ Segment and Geographic Information Contract Balances Unbilled Contracts Receivable Timing of revenue recognition may differ significantly from the timing of invoicing to customers. Accounts receivable, net, includes amounts billed and currently due from customers. Unbilled contracts receivable represents unbilled amounts expected to be received from customers in future periods, where the revenue recognized to date (or cumulative adjustments to retained earnings in the initial period of adopting Topic 606) exceeds the amount billed, and right to payment is subject to the underlying contractual terms. Unbilled contracts receivable amounts may not exceed their net realizable value and are classified as long-term assets if the payments are expected to be received more than one year from the reporting date. Deferred Revenue Deferred revenue includes payments made by licensees for which the corresponding performance obligations have not yet been fully satisfied by the Company and typically arises where performance obligations are satisfied over time. Allowance for Credit Losses The allowance for credit losses, which includes the allowance for accounts receivable and unbilled contracts receivable, represents the Company’s best estimate of lifetime expected credit losses inherent in those financial assets. The Company’s lifetime expected credit losses are determined using relevant information about past events, including historical experience, current conditions and reasonable and supportable forecasts that affect collectability. The Company monitors its credit exposure through ongoing credit evaluations of its customers’ financial condition and limits the amount of credit extended when deemed necessary.

Investments Debt And Equity Securities [Abstract]
Financial Instruments	NOTE 5 – FINANCIAL INSTRUMENTS The Company has investments in debt securities which include corporate bonds and notes, treasury and agency notes and bills, commercial paper, certificates of deposit, and in equity securities consisting of money market funds and common equity securities of a publicly traded Japanese company. The Company classifies its debt securities as available-for-sale (“AFS”), which are accounted for at fair value with credit related losses recognized as a provision for credit loss expense in its Condensed Consolidated Statements of Operations and all non-credit related unrealized gains and losses recognized in accumulated other comprehensive income or loss on the Condensed Consolidated Balance Sheets. Under ASU 2016-01 (Topic 321), equity securities are measured at fair value with unrealized gains and losses recognized in other income and expense, net, on the Condensed Consolidated Statements of Operations. The following is a summary of marketable securities at March 31, 2020 and December 31, 2019 (in thousands): March 31, 2020 Cost Gross Unrealized Gains Gross Unrealized Losses Allowance for Credit Losses Estimated Fair Values Marketable securities Corporate bonds and notes $ 32,608 $ 16 $ (272 ) $ — $ 32,352 Commercial paper 1,324 1 — — 1,325 Total debt securities 33,932 17 (272 ) — 33,677 Money market funds 34,791 — — — 34,791 Marketable equity securities 3,405 — (3,015 ) — 390 Total equity securities 38,196 — (3,015 ) — 35,181 Total marketable securities $ 72,128 $ 17 $ (3,287 ) $ — $ 68,858 Reported in: Cash and cash equivalents $ 34,791 Available-for-sale debt securities 33,677 Equity securities 390 Total marketable securities $ 68,858 December 31, 2019 Cost Gross Unrealized Gains Gross Unrealized Losses Estimated Fair Values Marketable securities Corporate bonds and notes $ 41,730 $ 29 $ (13 ) $ 41,746 Commercial paper 4,052 4 — 4,056 Total debt securities 45,782 33 (13 ) 45,802 Money market funds 2,601 — — 2,601 Marketable equity securities 3,405 — (2,281 ) 1,124 Total equity securities 6,006 — (2,281 ) 3,725 Total marketable securities $ 51,788 $ 33 $ (2,294 ) $ 49,527 Reported in: Cash and cash equivalents $ 2,601 Available-for-sale debt securities 45,802 Equity securities 1,124 Total marketable securities $ 49,527 At March 31, 2020 and December 31, 2019, the Company had $142.5 million and $121.5 million, respectively, in cash, cash equivalents and short-term investments. These balances include $73.6 million and $72.0 million in cash held in operating accounts not included in the tables above at March 31, 2020 and December 31, 2019, respectively. Debt Securities The gross realized gains and losses on sales of marketable debt securities were not significant during the three months ended March 31, 2020 and 2019, respectively. Unrealized losses on marketable debt securities were $0.3 million and $0.1 million, net of tax, as of March 31, 2020 and December 31, 2019, respectively. The Company evaluated whether the decline in fair value has resulted from credit losses or other factors and concluded these amounts were related to temporary fluctuations in value of AFS securities and were due primarily to changes in interest rates and market conditions of the underlying securities. In addition, the contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost bases of the investments. The Company does not intend to sell the investments and it is more likely than not that it will not be required to sell the investments before recovery of their amortized cost bases. For the three months ended March 31, 2020, the Company did not recognize a provision for credit loss expense related to its AFS debt securities. For the three months ended March 31, 2019, the Company did not record any impairment charges related to its AFS debt securities. The following table summarizes the fair value and gross unrealized losses related to individual AFS debt securities at March 31, 2020 and December 31, 2019, which have been in a continuous unrealized loss position, aggregated by investment category and length of time (in thousands): Less Than 12 Months 12 Months or More Total March 31, 2020 Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses Corporate bonds and notes $ 21,256 $ (265 ) $ 3,995 $ (7 ) $ 25,251 $ (272 ) Total $ 21,256 $ (265 ) $ 3,995 $ (7 ) $ 25,251 $ (272 ) Less Than 12 Months 12 Months or More Total December 31, 2019 Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses Corporate bonds and notes $ 20,031 $ (10 ) $ 8,753 $ (3 ) $ 28,784 $ (13 ) Total $ 20,031 $ (10 ) $ 8,753 $ (3 ) $ 28,784 $ (13 ) The estimated fair value of marketable debt securities by contractual maturity at March 31, 2020 is shown below (in thousands). Actual maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations without call or prepayment penalties. Estimated Fair Value Due in one year or less $ 23,548 Due in one to two years 10,129 Total $ 33,677 Equity Securities On September 19, 2018, the Company purchased seven million common shares of Onkyo Corporation (“Onkyo”), a publicly traded Japanese company and a long-standing customer of the Company, pursuant to the Capital Alliance Agreement (“Agreement”) entered into between the two parties on September 3, 2018. Upon making the investment, the Company held a 6.3% ownership interest in Onkyo. Due to changes in business expectations, the Company determined not to continue discussions on the business alliance. On July 5, 2019, the Company sold approximately 2.8 million shares of Onkyo stock and realized a gain of $0.9 million. There were no sales of the Onkyo investment during the three months ended March 31, 2020 and 2019. The Company intends to sell the remaining shares over time depending on market conditions. The Company recorded unrealized losses on its Onkyo investment of $0.7 million and $0.4 million during the three months ended March 31, 2020 and 2019, respectively. Cumulative unrealized losses on the investment amounted to $3.0 million through March 31, 2020. Derivatives From time to time , the Company may use derivative financial instruments to manage foreign currency exchange rate risk. The Company does not enter into derivative transactions for trading purposes. Cash flows from the derivative programs are classified as cash flows from operating activities in the Condensed Consolidated Statement Cash Flows The Company’s derivative financial instruments consist of deliverable and non-deliverable foreign currency forward contracts, which are used primarily to hedge balance sheet and certain expenditure exposures. These instruments are generally short-term in nature, with typical maturities of less than one year, and are subject to fluctuations in foreign exchange rates. Fair values for derivative financial instruments are based on prices computed using third-party valuation models and are classified as Level 2 in accordance with the three-level hierarchy of fair value measurements. All significant inputs to the third-party valuation models are observable in active markets. Inputs include current market-based parameters such as forward rates, yield curves and credit default swap pricing. For additional information related to the three-level hierarchy of fair value measurements, s ee “ Under the Company’s policy election, these derivatives are not designated as hedge instruments, which are measured and reported at fair value. Changes in the fair value of these undesignated derivatives are reported in other income and expense, net, on the Condensed Consolidated Statements of Operations. Realized losses and changes in the estimated fair value of the derivatives were not significant in the three months ended March 31, 2020 and 2019.

Fair Value Disclosures [Abstract]
Fair Value	NOTE 6 – FAIR VALUE The Company follows the authoritative guidance for fair value measurement and the fair value option for financial assets and financial liabilities. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability, or an exit price, in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The established fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value: Level 1 Quoted prices in active markets for identical assets. Level 2 Observable market-based inputs or unobservable inputs that are corroborated by market data. Level 3 Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. When applying fair value principles in the valuation of assets, the Company is required to maximize the use of quoted market prices and minimize the use of unobservable inputs. The Company calculates the fair value of its Level 1 and Level 2 instruments based on the exchange traded price of similar or identical instruments, where available, or based on other observable inputs. There were no significant transfers into or out of Level 1 or Level 2 that occurred between December 31, 2019 and March 31, 2020. The following sets forth the fair value, and classification within the hierarchy, of the Company’s assets required to be measured at fair value on a recurring basis as of March 31, 2020 (in thousands): Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets Marketable securities Money market funds - equity securities (1) $ 34,791 $ 34,791 $ — $ — Marketable equity securities (2) 390 390 Corporate bonds and notes - debt securities (3) 32,352 — 32,352 — Commercial paper - debt securities (3) 1,325 — 1,325 — Total Assets $ 68,858 $ 35,181 $ 33,677 $ — (1) Reported as cash and cash equivalents in the Condensed Consolidated Balance Sheet.

The Company's reporting units include the Product Licensing segment and the Semiconductor and IP Licensing segment. Of the carrying value of goodwill, approximately $378.1 million was allocated to the Product Licensing segment and approximately $7.7 million was allocated to the Semiconductor and IP Licensing segment During the first quarter of 2020, the COVID-19 pandemic rapidly spread globally and has created unprecedented disruptions in economic activity and financial markets. Due to resulting changes in macroeconomic conditions, industry outlook, and a meaningful decline in the Company’s share price, indicators of potential goodwill impairment were identified. The Company proceeded with a quantitative interim goodwill impairment test as of March 31, 2020. Based on the quantitative assessment, the Company concluded that the fair value of the reporting units exceeded the carrying amount for both Product Licensing and Semiconductor and IP Licensing. As a result, no goodwill impairment charges were recognized in the three months ended March 31, 2020 .

Diluted net income (loss) per share is computed using the treasury stock method to calculate the weighted average number of common shares and, if dilutive, potential common shares outstanding during the period. Potential dilutive common shares include unvested restricted stock awards and units and incremental common shares issuable upon the exercise of stock options, less shares from assumed proceeds. The assumed proceeds calculation includes actual proceeds to be received from the employee upon exercise and the average unrecognized stock compensation cost during the period. For the three months ended March 31, 2020, 2.1 million shares subject to stock options and restricted stock awards and units were excluded from the computation of diluted net income per share as they were anti-dilutive. For the three months ended March 31, 2019, there was no difference in the weighted average number of common shares used for the calculation of basic and diluted loss per share as the effect of all potentially dilutive shares outstanding was anti-dilutive. A total of 2.1 million shares subject to stock options and restricted stock awards and units were excluded from the computation of diluted net loss per share for the three months ended March 31, 2019, because including them would have been anti-dilutive.

Income Taxes	NOTE 12 – INCOME TAXES For the three months ended March 31, 2020, the Company recorded an income tax expense of $2.1 million on pretax income of $20.8 million, which resulted in an effective tax rate of 9.9%. The income tax expense for the three months ended March 31, 2020 was primarily related to tax expense from operating income, increase in certain non-deductible expenses, shortfalls from stock-based compensation, increase in valuation allowance on certain deferred tax assets, and unrealized foreign exchange losses from the prior year Korea refund claim, offset by a deduction from foreign-derived intangible income and the release of unrecognized tax benefits due to lapse in statute of limitation. For the three months ended March 31, 2019, the Company recorded an income tax benefit of $9.0 million on a pretax loss of $34.4 million, which resulted in an effective tax rate of 26.0%. The effective tax rate was primarily related to tax benefit from operating losses and the realization of certain tax credits, offset by foreign withholding taxes, certain non-deductible expenses, and shortfalls from stock-based compensation. The Company's provision for income taxes is based on its worldwide estimated annualized effective tax rate, except for jurisdictions for which a loss is expected for the year and no benefit can be realized for those losses, and the tax effect of discrete items occurring during the period. The tax for jurisdictions for which a loss is expected and no benefit can be realized for the year is based on actual taxes and tax reserves for the quarter. The change from income tax benefit to income tax expense for the period ended March 31, 2020 as compared to the prior year is largely attributable to operating income, increase in certain non-deductible expenses and unrealized foreign exchange loss from the Korean refund claim partially offset by tax benefits from the release of unrecognized tax benefits due to lapse in statute of limitation. During the fourth quarter of 2019, the Company filed a refund claim for foreign taxes previously withheld from licensees in Korea based on recent court rulings in Korea and other business factors. These previously withheld foreign taxes were claimed as a foreign tax credit in the U.S. As a result of the Company’s refund claim, it recorded a non-current income tax receivable of $65.2 million in income tax receivable, an unrecognized tax benefit of $48.2 million in other long-term liabilities, and a reduction in deferred tax assets of $17.0 million. The Company anticipates filing a refund claim for the 2020 year-to-date Korean withholding taxes. During the first quarter of 2020, an additional non-current income tax receivable of $ 4.8 million, an unrecognized tax benefit of $ 2.4 million in other long-term liabilities, and a reduction in deferred tax assets of $ 2.3 million were recorded . At March 31, 2020, the Company had recorded a cumulative unrealized foreign exchange loss of approximately $ 3.9 million as a reduction in non-current income tax receivable . As of March 31, 2020, unrecognized tax benefits were $85.5 million (which is included in long-term deferred tax and other long-term liabilities on the Condensed Consolidated Balance Sheet), of which $81.6 million would affect the effective tax rate if recognized. As of March 31, 2019, unrecognized tax benefits were $33.7 million (which was included in long-term deferred tax and other long-term liabilities on the Condensed Consolidated Balance Sheet), of which $21.3 million would affect the effective tax rate if recognized. The Company is unable to reasonably estimate the timing of the long-term payments or the amount by which the liability will increase or decrease. It is the Company's policy to classify accrued interest and penalties related to unrecognized tax benefits in the provision for income taxes. For the three months ended March 31, 2020 and 2019, the Company recognized an insignificant amount of interest and penalties related to unrecognized tax benefits. Accrued interest and penalties were $1.1 million and $1.2 million as of March 31, 2020 and December 31, 2019, respectively. At March 31, 2020, the Company’s

Leases [Abstract]
Leases	NOTE 13 – LEASES The Company leases office and research facilities and office equipment under operating leases which expire through 2028. The Company’s leases have remaining lease terms of one year to nine years, some of which may include options to extend the leases for five years or longer, and some of which may include options to terminate the leases within one year or less. Leases with an initial term of 12 months or less are not recorded; expense for these leases is recognized on a straight-line basis over the lease term. Variable lease payments are expensed as incurred and are not included within the lease liability and right-of-use assets calculation. As a practical expedient, the Company elected, for all office and facility leases, not to separate nonlease components (e.g., common-area maintenance costs) from lease components (e.g., fixed payments including rent) and instead to account for each separate lease component and its associated non-lease components as a single lease component. As most of the leases do not provide an implicit rate, the Company generally, for purposes of discounting lease payments, uses its incremental borrowing rate based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments at commencement date. Lease cost is summarized in the table below (in thousands): Three Months Ended March 31, 2020 March 31, 2019 Operating lease cost (1) $ 2,181 $ 1,951 (1) Includes short-term leases and variable lease costs, which were immaterial.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	NOTE 14 – COMMITMENTS AND CONTINGENCIES Purchase and Other Commitments There have been no material changes to the Company’s purchase and other commitments in the three months ended March 31, 2020. For detail, refer to “Note 15 – Commitments and Contingencies” Leases The Company leases office and research facilities and office equipment under operating leases which expire at various dates through 2028. The terms of some of the Company’s leases provide for rental payments on a graduated scale. Lease expense is recorded on a straight-line basis over the lease term. For further details, refer to “Note 13 – Leases.” Contingencies At each reporting period, the Company evaluates whether or not a potential loss amount or a potential range of loss is probable and reasonably estimable under the provisions of the authoritative guidance that addresses accounting for contingencies. The Company is currently unable to predict the final outcome of lawsuits to which it is a party and therefore cannot determine the likelihood of loss nor estimate a range of possible loss. An adverse decision in any of these proceedings could significantly harm the Company’s business and consolidated financial position, results of operations or cash flows. The Company and its subsidiaries are involved in litigation matters and claims in the normal course of business. In the past, the Company and its subsidiaries have litigated to enforce their respective patents and other intellectual property rights, to enforce the terms of license agreements, to protect trade secrets, to determine the validity and scope of the proprietary rights of others and to defend itself or its customers against claims of infringement or invalidity. The Company expects it or its subsidiaries will be involved in similar legal proceedings in the future, including proceedings regarding infringement of its patents, and proceedings to ensure proper and full payment of royalties by licensees under the terms of its license agreements. The existing and any future legal actions may harm the Company’s business. For example, legal actions could cause an existing licensee or strategic partner to cease making royalty or other payments to the Company, or to challenge the validity and enforceability of patents owned by the Company’s subsidiaries or the scope of license agreements with the Company’s subsidiaries, and could significantly damage the Company’s relationship with such licensee or strategic partner and, as a result, prevent the adoption of the Company’s other technologies by such licensee or strategic partner. Litigation could also severely disrupt or shut down the business operations of licensees or strategic partners of the Company’s subsidiaries, which in turn would significantly harm ongoing relations with them and cause the Company to lose royalty revenue. The costs associated with legal proceedings are typically high, relatively unpredictable, and not completely within the Company’s control. These costs may be materially higher than expected, which could adversely affect the Company’s operating results and lead to volatility in the price of its common stock. Whether or not determined in the Company’s favor or ultimately settled, litigation diverts managerial, technical, legal, and financial resources from the Company’s business operations. Furthermore, an adverse decision in any of these legal actions could result in a loss of the Company’s proprietary rights, subject the Company to significant liabilities, require the Company to seek licenses from others, limit the value of the Company’s licensed technology or otherwise negatively impact the Company’s stock price or its business and consolidated financial position, results of operations or cash flows.

Segment and Geographic Informat

Segment and Geographic Information	3 Months Ended

Segment Reporting [Abstract]
Segment and Geographic Information	NOTE 15 – SEGMENT AND GEOGRAPHIC INFORMATION The Company reports its financial results within two reportable segments: (1) Product Licensing and (2) Semiconductor and IP Licensing. There are certain corporate overhead costs that are not allocated to these reportable segments because these operating amounts are not considered in evaluating the operating performance of the Company’s business segments. The Chief Executive Officer is also the Chief Operating Decision Maker (“CODM”) as defined by the authoritative guidance on segment reporting. The Product Licensing segment is comprised of the Company’s audio and imaging businesses, which the Company licenses through the DTS, HD Radio, and IMAX Enhanced brands. These licenses typically include the delivery of software and/or hardware-based solutions to the Company’s customers or to their suppliers. Product Licensing revenue is derived primarily from sales into the home, automotive and mobile markets. The Semiconductor and IP Licensing segment includes the Company’s Tessera, Invensas and Invensas Bonding Technologies subsidiaries, which license semiconductor packaging and interconnect technologies and associated IP. Semiconductor and IP Licensing revenue is derived from technology and IP licenses to semiconductor companies, foundries and packaging companies. The Company has a long history of developing and monetizing next-generation technologies, including chip-scale and multi-chip packaging solutions as well as low-temperature wafer and die bonding solutions. Today, the Company is actively developing and licensing 3D semiconductor packaging, interconnect and bonding solutions for semiconductors that are used in everyday products such as smartphones, tablets, and laptops as well as servers used in datacenters. The Company also provides engineering services to its customers to assist them in their evaluation and adoption of the Company’s technologies including the transition into high volume production. The Company does not identify or allocate assets by reportable segment, nor does the CODM evaluate reportable segments using discrete asset information. Reportable segments do not record inter-segment revenue and accordingly there are none to report. The Company does not allocate other income and expense to reportable segments. Although the CODM uses operating income to evaluate reportable segments, operating costs included in one segment may benefit other segments. The following table sets forth the Company’s segment revenue, operating expenses and operating income (loss) for the three months ended March 31, 2020 and 2019 (in thousands): Three Months Ended March 31, 2020 March 31, 2019 Revenue: Product Licensing segment $ 55,942 $ 44,567 Semiconductor and IP Licensing segment 61,723 12,000 Total revenue 117,665 56,567 Operating expenses: Product Licensing segment 45,166 45,757 Semiconductor and IP Licensing segment 10,169 10,238 Unallocated operating expenses (1) 37,803 30,569 Total operating expenses 93,138 86,564 Operating income (loss): Product Licensing segment 10,776 (1,190 ) Semiconductor and IP Licensing segment 51,554 1,762 Unallocated operating expenses (1) (37,803 ) (30,569 ) Total operating income (loss) $ 24,527 $ (29,997 ) (1) Unallocated operating expenses consist primarily of selling, general and administrative expenses, such as administration, human resources, finance, information technology, corporate development and procurement. These expenses are not allocated because these amounts are not considered in evaluating the operating performance of the Company’s business segments. A significant portion of the Company’s revenue is derived from licensees headquartered outside of the U.S., principally in Asia, and it is expected that this revenue will continue to account for a significant portion of total revenue in future periods. The table below lists the geographic revenue for the periods indicated (in thousands): Three Months Ended March 31, 2020 March 31, 2019 Japan $ 51,322 44 % $ 17,232 31 % Korea 27,583 23 17,503 31 U.S. 23,136 20 11,432 20 China 8,846 7 3,443 6 Europe and Middle East 4,448 4 4,000 7 Other 2,330 2 2,957 5 $ 117,665 100 % $ 56,567 100 % For the three months ended March 31, 2020 and 2019, there were two customers and one customer, respectively, that accounted for 10% or more of total revenue. As of March 31, 2020 and December 31, 2019, there were two and three customers, respectively, that each accounted for 10% or more of total accounts receivable.

Accounting Policies [Abstract]
Basis of Accounting	The accompanying interim unaudited condensed consolidated financial statements as of March 31, 2020 and 2019, and for the three months then ended, have been prepared by the Company in accordance with generally accepted accounting principles (“GAAP”) in the United States (“U.S.”) for interim financial information. The amounts as of December 31, 2019 have been derived from the Company’s annual audited financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted in accordance with such rules and regulations. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments necessary (consisting of normal recurring adjustments) to state fairly the financial position of the Company and its results of operations and cash flows as of and for the periods presented. These financial statements should be read in conjunction with the annual audited financial statements and notes thereto as of and for the year ended December 31, 2019, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, filed on February 18, 2020 (the “Form 10-K”).
Reclassification	Reclassification Certain reclassifications have been made to prior period balances in order to conform to the current period’s presentation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. The accounting estimates and assumptions that require management’s most significant, difficult, and subjective judgment include the estimation of licensees’ quarterly royalties prior to receiving the royalty reports, the collectability of accounts receivable, the fair value measurements of goodwill, other intangible assets and investments, the assessment of the recoverability of goodwill, the assessment of useful lives and recoverability of other intangible assets and long-lived assets, recognition and measurement of current and deferred income tax assets and liabilities, the assessment of unrecognized tax benefits and the valuation and recognition of stock-based compensation expense, and business combinations, among others. Actual results experienced by the Company may differ from management’s estimates. The worldwide spread of the COVID-19 virus is expected to result in a global slowdown of economic activity which is likely to decrease demand for a broad variety of goods and services, while also disrupting sales channels, marketing activities and supply chains for an unknown period of time until the disease is contained. The Company expects this to have a negative impact on its revenue, billings and results of operations, the size and duration of which it is currently unable to predict. The Company anticipates that the impact of the COVID-19 virus will increase volatility and make the estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes more difficult, however, as of the date of issuance of the financial statements, the Company is not aware of any specific event or circumstance that would require it to update its estimates, judgments or revise the carrying value of its assets or liabilities. These estimates may change, as new events occur and additional information is obtained, and are recognized in the consolidated financial statements as soon as they become known.
Recent Accounting Pronouncements	Recently Adopted Accounting Pronouncements In September 2016, the Financial Accounting Standards Board (“FASB”) issued Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments Revenue Recent Accounting Pronouncements On December 18, 2019, FASB released ASU 2019-12, “ Simplifying the Accounting for Income Taxes ASU 2019-12 is effective for the Company in the first quarter of the year ending December 31, 2021. The Company is in the process of evaluating the impact of the adoption of this new standard on its consolidated financial statements.
Revenue Recognition	Revenue Recognition The Company derives its revenue primarily from royalty and license fees for rights to use the Company’s intellectual property and technologies (“IP”). Revenue is recognized upon transfer of control of promised products, services or IP rights to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products, services or licensing of the IP rights. Certain licensees have entered into fixed fee or minimum guarantee arrangements, whereby licensees pay a fixed fee for the right to incorporate the Company’s technology in the licensee's products over the license term. In arrangements with a minimum guarantee, the fixed fee component corresponds to a minimum number of units or dollars that the customer must produce or pay, with additional per-unit fees for any units or dollars exceeding the minimum. In most cases, the customer pays the fixed license fee in specified installments over the license term. For both fixed fee and minimum guarantee agreements, the Company recognizes the full fixed fee as revenue at the beginning of the license term, when the licensee has the right to use the IP and begins to benefit from the license. If the contract term of a fixed fee or minimum guarantee arrangement is longer than one year, the Company also considers the scheduled payment arrangements to determine whether a significant financing component exists. In general, if the payment arrangements extend beyond the initial twelve months of the contract, the Company treats a portion of the payments as a significant financing component. When the payments are expected to be received within one year or less, the Company does not adjust the promised amount of consideration for the effects of a financing component. The discount rate used for each arrangement reflects the rate that would be used in a separate financing transaction between the Company and the licensee at contract inception and takes into account the credit characteristics of the licensee and market interest rates as of the date of the agreement. As such, the amount of fixed fee revenue recognized at the beginning of the license term will be reduced by the calculated financing component. As payments are received from the licensee, the Company recognizes a portion of the financing component as interest income, reported as other income and expense in the Condensed Consolidated Statements of Operations. For certain licensees, royalty revenues are generated based on a licensee’s production or shipment of licensed products incorporating the Company’s IP, technologies or software. Licensees with a per-unit arrangement pay a per-unit royalty for each product manufactured or sold, as set forth in its license agreement. Licensees generally report manufacturing or sales information in the quarter subsequent to when the production or shipment activity takes place. The Company estimates the royalties earned each quarter based on its forecast of manufacturing and sales activity incurred by its licensees in that quarter. Any differences between actual royalties owed by a licensee and the Company’s quarterly estimate are recognized in the following quarter, when the licensee’s royalty report is received. Estimating licensees’ quarterly royalties prior to receiving the royalty reports requires the Company to make significant assumptions and judgments related to forecasted trends and growth rates used to estimate quantities shipped by customers, which could have a material impact on the amount of revenue it reports on a quarterly basis. The Company actively monitors and enforces its IP, including seeking appropriate compensation from customers that have under-reported royalties owed under a license agreement and from third parties that utilize the Company’s intellectual property without a license. As a result of these activities, the Company may, from time to time, recognize revenue from payments resulting from periodic compliance audits of licensees for underreporting royalties incurred in prior periods, as part of a settlement of a patent infringement dispute, or from legal judgments in a license dispute. These recoveries and settlements may cause revenue to be higher than expected during a particular reporting period and such recoveries may not occur in subsequent periods. The Company recognizes revenue from recoveries when a binding agreement has been executed and the Company concludes collection under that agreement is likely. In some instances, the Company may enter into license agreements containing multiple performance obligations that include engineering services in addition to a technology or software license. For such arrangements where all components are capable of being distinct and accounted for as separate performance obligations, the Company allocates revenue to each performance obligation based on its relative standalone selling price. The Company generally determines standalone selling prices based on the prices ordinarily charged to customers, or in some cases by applying a reasonable cost-plus margin. The consideration for engineering services is recognized as the underlying performance obligations are satisfied. Generally, the Company satisfies performance obligations over time and therefore recognizes revenue over time by measuring the progress toward completion of the performance obligation at each reporting period. From time to time, the Company enters into arrangements with licensees in which the Company pays consideration to the licensee. Such payments can take the form of marketing development funds or various rebate incentives. The Company typically accounts for consideration paid to its licensees as a reduction to the transaction price and revenue, unless the payment to the licensee is in exchange for a distinct good or service that the licensee transfers to the Company. In cases where the consideration paid to the licensee is variable, the Company estimates the variable consideration based on the terms of the arrangement and expectations of future outcomes. The Company recognizes the reduction to revenue when it recognizes revenue for transfer of control of promised products, services or IP rights to the licensee. Revenue is recognized gross of withholding taxes that are remitted directly by the Company’s licensees to a local tax authority.
