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 are embedded in more than 25% of smartphones on the market today. 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 June 30, 2019 and 2018, and for the three and six 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, 2018 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, 2018, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018, filed on February 20, 2019 (the “Form 10-K”). The results of operations for the three and six months ended June 30, 2019 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2019 or any future period and the Company makes no representations related thereto. In the fourth quarter of 2018, the Company funded a new entity and issued shares to non-controlling interests. At the end of the fourth quarter of 2018, the entity was approximately 85% owned by the Company. As a result of issuing new shares in such entity to noncontrolling interests during the first six months of 2019, the Company’s ownership interest of the entity decreased to approximately 84% as of June 30, 2019. The operating results of this entity have been consolidated in the Company’s consolidated financial statements since the fourth quarter of 2018. 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.”

Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	NOTE 2 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The Company’s significant accounting policies are detailed in “Note 2 - Summary of Significant Accounting Policies” Leases Leases Recently Adopted Accounting Pronouncements In June 2018, the Financial Accounting Standards Board (“FASB”) issued Stock-based Compensation: Improvements to Nonemployee Share-based Payment Accounting,” In February 2016, the FASB issued ASU No. 2017-12, “ Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, In February 2016, the FASB issued ASU No. 2016-02, " Leases modified retrospective transition approach and elected the transition option The Company elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed it to carry forward the historical lease classification. Under the optional transition method, the Company opted to continue to apply the legacy guidance in ASC 840, Leases, including its disclosure requirements, in the comparative periods presented in the year it adopted the new leases standard, and therefore did not restate prior period results. The most significant impact from adopting Topic 842 was the initial recognition of operating lease ROU assets and operating lease liabilities of $17.6 million and $18.8 million, respectively, as of January 1, 2019. Operating lease liabilities consist of both current and noncurrent portions with the current portion included in the balance of accrued liabilities. The standard did not materially impact the Company’s Condensed Consolidated Statements of Operations and had no impact on cash flows. The cumulative effect of the changes made to the Company's Condensed Consolidated Balance Sheet as of January 1, 2019 for the adoption of Topic 842 was as follows (in thousands): Balance at December 31, 2018 Adjustments due to Topic 842 Balance at January 1, 2019 Assets Operating lease right-of-use assets $ — $ 17,594 $ 17,594 Liabilities Accrued liabilities $ 45,336 $ 3,858 (1) $ 49,194 Noncurrent operating lease liabilities $ — $ 13,736 $ 13,736 (1) Consists of a debit adjustment of $1.2 million to deferred rent to eliminate the existing balance and a credit adjustment of $5.1 million to record the current portion of operating lease liabilities.

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 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 that 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. Additional Disclosures Under Topic 606 The following table presents additional revenue and contract disclosures (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2019 2018 2019 2018 Revenue recognized in the period from: Amounts included in deferred revenue at the beginning of the period $ 2,124 $ 1,642 $ 3,167 $ 1,995 Performance obligations satisfied in previous periods (true ups and licensee reporting adjustments)* $ 2,472 $ 54 $ 3,637 $ 54 *True ups represent the differences between the Company’s quarterly estimates of per unit royalty revenue and actual production/sales-based royalties reported by licensees in the following period. Licensee reporting adjustments represent corrections or revisions to previously reported per unit royalties by licensees, generally resulting from the Company’s inquiries or compliance audits. Remaining revenue under contracts with performance obligations represents the aggregate amount of the transaction price allocated to the performance obligations that are unsatisfied (or partially unsatisfied) under the Company’s engineering services contracts. The Company's remaining revenue under contracts with performance obligations was as follows (in thousands): As of June 30, 2019 December 31, 2018 Revenue from contracts with performance obligations expected to be satisfied in: One year or less $ 867 $ 3,080 More than one year but less than two years — 2,289 Total $ 867 $ 5,369 Practical Expedients The Company expenses sales commissions when incurred because the amortization period generally would have been one year or less. In addition, sales commissions have historically not been a significant expense and are not contemplated to be significant in the future. Sales commissions are recorded in selling, general and administrative expenses in the Condensed Consolidated Statements of Operations.

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, which are accounted for at fair value with unrealized gains and losses recognized in accumulated other comprehensive gain 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 Statement of Operations. The following is a summary of marketable securities at June 30, 2019 and December 31, 2018 (in thousands): June 30, 2019 Cost Gross Unrealized Gains Gross Unrealized Losses Estimated Fair Values Marketable securities Corporate bonds and notes $ 34,510 $ 14 $ (70 ) $ 34,454 Commercial paper 2,292 5 — 2,297 Treasury and agency notes and bills 6,000 — (9 ) 5,991 Total debt securities 42,802 19 (79 ) 42,742 Marketable equity securities 5,662 — (594 ) 5,068 Total equity securities 5,662 — (594 ) 5,068 Total marketable securities $ 48,464 $ 19 $ (673 ) $ 47,810 Reported in: Cash and cash equivalents $ — Short-term investments 47,810 Total marketable securities $ 47,810 December 31, 2018 Cost Gross Unrealized Gains Gross Unrealized Losses Estimated Fair Values Marketable securities Corporate bonds and notes $ 28,623 $ — $ (275 ) $ 28,348 Commercial paper 2,999 — — 2,999 Treasury and agency notes and bills 6,000 — (53 ) 5,947 Total debt securities 37,622 — (328 ) 37,294 Money market funds 11,499 — — 11,499 Marketable equity securities 5,662 — (2,217 ) 3,445 Total equity securities 17,161 — (2,217 ) 14,944 Total marketable securities $ 54,783 $ — $ (2,545 ) $ 52,238 Reported in: Cash and cash equivalents $ 11,499 Short-term investments 40,739 Total marketable securities $ 52,238 At June 30, 2019 and December 31, 2018, the Company had $98.3 million and $154.4 million, respectively, in cash, cash equivalents and short-term investments. These balances include $50.5 million and $102.1 million in cash held in operating accounts not included in the tables above at June 30, 2019 and December 31, 2018, respectively. Debt Securities The gross realized gains and losses on sales of marketable debt securities were not significant during the three and six months ended June 30, 2019 and 2018, respectively. Unrealized losses on marketable debt securities were $0.1 million and $0.3 million, net of tax, as of June 30, 2019 and December 31, 2018, respectively. These amounts were related to temporary fluctuations in value of available-for-sale securities and were due primarily to changes in interest rates and market and credit conditions of the underlying securities. Certain investments with a temporary decline in value are not considered to be other-than-temporarily impaired as of June 30, 2019 because the Company has the intent and ability to hold these investments to allow for recovery, does not anticipate having to sell these securities with unrealized losses and continues to receive interest at the maximum contractual rate. For the three and six months ended June 30, 2019 and 2018, respectively, the Company did not record any impairment charges related to its marketable debt securities. The following table summarizes the fair value and gross unrealized losses related to individual available-for-sale debt securities at June 30, 2019 and December 31, 2018, 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 June 30, 2019 Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses Corporate bonds and notes $ 11,477 $ (20 ) $ 16,044 $ (50 ) $ 27,521 $ (70 ) Treasury and agency notes and bills 5,991 (9 ) — — 5,991 (9 ) Total $ 17,468 $ (29 ) $ 16,044 $ (50 ) $ 33,512 $ (79 ) Less Than 12 Months 12 Months or More Total December 31, 2018 Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses Corporate bonds and notes $ 5,488 $ (2 ) $ 22,860 $ (273 ) $ 28,348 $ (275 ) Commercial paper 2,999 — — — 2,999 — Treasury and agency notes and bills — — 5,947 (53 ) 5,947 (53 ) Total $ 8,487 $ (2 ) $ 28,807 $ (326 ) $ 37,294 $ (328 ) The estimated fair value of marketable debt securities by contractual maturity at June 30, 2019 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 $ 27,258 Due in one to two years 15,484 Total $ 42,742 Equity Securities There were no realized gains or losses on sales of equity securities during the three and six months ended June 30, 2019 and 2018. 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 and had one representative appointed to the board of directors of a subsidiary of Onkyo in November 2018. The Agreement contemplated that the parties would negotiate a business alliance agreement aimed at collaborating on certain new product development. On May 14, 2019, Sound United LLC announced that it had entered into a term sheet agreement to acquire Onkyo’s consumer audio division. Given the anticipated acquisition, the Company determined not to continue discussions on the business alliance and determined not to appoint a representative to serve on the board of directors of Onkyo. On July 5, 2019, the Company sold approximately 2.8 million shares of Onkyo stock . The Company intends to sell the remaining shares over time depending on market conditions. The Company had unrealized gains on its Onkyo investment of $2.0 million and $1.6 million during the three and six months ended June 30, 2019, respectively, and none for the three and six months ended June 30, 2018. Cumulative unrealized losses on the investment amounted to $0.6 million through June 30, 2019. 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, and 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 were not significant in the three and six months ended June 30, 2019. There were no derivative instruments outstanding as of June 30, 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, 2018 and June 30, 2019. The following is a list of the Company’s assets required to be measured at fair value on a recurring basis and where they were classified within the hierarchy as of June 30, 2019 (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 Marketable equity securities (1) $ 5,068 $ 5,068 $ — $ — Commercial paper - debt securities (1) 2,297 — 2,297 — Corporate bonds and notes - debt securities (1) 34,454 — 34,454 — Treasury and agency notes and bills - debt securities (1) 5,991 — 5,991 — Total Assets $ 47,810 $ 5,068 $ 42,742 $ — The following footnotes indicate where the noted items were recorded in the Condensed Consolidated Balance Sheet at June 30, 2019: (1) Reported as short-term investments.

Debt	NOTE 8 - DEBT On December 1, 2016, in connection with the consummation of the acquisition of DTS, the Company entered into a Credit Agreement (the “Credit Agreement”) by and among the Company, Royal Bank of Canada, as administrative agent and collateral agent, and the lenders party thereto. The Credit Agreement provided for a $600.0 million seven-year term B loan facility (the “Term B Loan Facility”) which matures on November 30, 2023. Upon the closing of the Credit Agreement, the Company borrowed $600.0 million under the Term B Loan facility. Net proceeds were used on December 1, 2016, together with cash and cash equivalents, to finance the acquisition of DTS. On January 23, 2018, the Company and the loan parties entered into an amendment to the Credit Agreement (the “Amendment”). In connection with the Amendment, the Company made a voluntary prepayment of $100.0 million of the term loan outstanding under the Credit Agreement using cash on hand. The Amendment provided for, among other things, (i) a replacement of the outstanding initial term loan with the new tranche term B-1 loan (the “Amended Term B Loan”) in a principal amount of $494.0 million, (ii) a reduction of the interest rate margin applicable to such loan to (x) in the case of Eurodollar loans, 2.50% per annum and (y) in the case of base rate loans, 1.50% per annum, (iii) a prepayment premium of 1.00% in connection with any repricing transaction with respect to the Amended Term B Loan within six months of the closing date of the Amendment, and (iv) certain amendments to provide the Company with additional flexibility under the covenant governing restricted payments. Using cash on hand, the Company made two voluntary prepayments of $50.0 million each on March 29, 2019 and June 28, 2019. The Company’s obligations under the Credit Agreement, as amended by the Amendment, continue to be guaranteed by substantially all of the Company’s subsidiaries, and secured by substantially all of the assets of the Company and its subsidiaries. The Credit Agreement contains customary events of default, upon the occurrence of which, after any applicable grace period, the lenders will have the ability to accelerate all outstanding loans thereunder. The Credit Agreement contains customary representations and warranties and affirmative and negative covenants that, among other things, restrict the ability of the Company to create or incur certain liens, incur or guarantee additional indebtedness, merge or consolidate with other companies, transfer or sell assets and make restricted payments. The Company was in compliance with all requirements during the three and six months ended June 30, 2019. At June 30, 2019, $394.0 million was outstanding with an interest rate, including the amortization of debt issuance costs, of 5.6%. Interest is payable monthly. There were also $10.6 million of unamortized debt issuance costs recorded as a reduction of the long-term portion of the debt. Interest expense was $6.2 million and $12.9 million for the three and six months ended June 30, 2019, respectively.

Earnings Per Share [Abstract]
Net Loss Per Share	NOTE 9 – NET LOSS PER SHARE The Company has a share-based compensation plan under which employees may be granted share-based awards including shares of restricted stock and restricted stock units ("RSUs"). Non-forfeitable dividends are paid on unvested shares of restricted stock. No dividends are accrued or paid on unvested RSUs. As such, shares of restricted stock are considered participating securities under the two-class method of calculating earnings per share. The two-class method of calculating earnings per share did not have a material impact on the Company’s loss per share calculation for the three and six months ended June 30, 2019 and 2018. The following table sets forth the computation of basic and diluted shares (in thousands): Three Months Ended Six Months Ended June 30, 2019 June 30, 2018 June 30, 2019 June 30, 2018 Denominator: Weighted average common shares outstanding 49,259 49,060 48,918 49,110 Less: shares of restricted stock subject to repurchase — — — — Total common shares-basic 49,259 49,060 48,918 49,110 Effect of dilutive securities: Options — — — — Restricted stock awards and units — — — — Total common shares-diluted 49,259 49,060 48,918 49,110 Basic net income (loss) per share is computed using the weighted average number of common shares outstanding during the period, excluding any unvested restricted stock awards that are subject to repurchase. 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 and six months ended June 30, 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 1.7 million and 1.7 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 and six months ended June 30, 2019, respectively, because including them would have been anti-dilutive. For the three and six months ended June 30 .

Income Tax Disclosure [Abstract]
Income Taxes	NOTE 12 – INCOME TAXES For the three months ended June 30, 2019, the Company recorded an income tax benefit of $3.5 million on a pretax loss of $9.7 million and for the six months ended June 30, 2019, the Company recorded an income tax benefit of $12.5 million on a pretax loss of $44.1 million, income tax benefit for the three and six months ended June 30, 2019 For the three months ended June 30, 2018, the Company recorded an income tax benefit of $3.3 million, on a pretax loss of $31.6 million and for the six months ended June 30, 2018, the Company recorded an income tax benefit of $6.0 million on a pretax loss of $67.2 million, The income tax benefit for the three and six months ended June 30, 2018 was primarily related to tax benefit from losses and credits generated from operations offset by foreign withholding taxes, certain book-to-tax permanent differences, valuation allowance recorded against the Company’s unutilized tax credits generated in the current year, 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 increase in income tax benefit for the six months ended June 30, 2019 as compared to the income tax benefit during the same period in the prior year is largely attributable to the realization of certain tax credits. As of June 30, 2019, unrecognized tax benefits were $33.9 million (which is 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. As of June 30, 2018, unrecognized tax benefits were $34.1 million (which was included in long-term deferred tax and other long-term liabilities on the Condensed Consolidated Balance Sheet), of which $22.2 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 six months ended June 30, 2019 and 2018, the Company recognized an insignificant amount of interest and penalties related to unrecognized tax benefits. Accrued interest and penalties were $1.1 million and $0.9 million as of June 30, 2019 and December 31, 2018, respectively. At June 30, 2019, the Company’s

Leases [Abstract]
Leases	NOTE 13 – LEASES Under Topic 842, a contract is a lease, or contains a lease, if the contract conveys the right to control the use of identified property, plant, or equipment (an identified asset) for a period of time in exchange for consideration. To determine whether a contract conveys the right to control the use of an identified asset for a period of time, an entity shall assess whether, throughout the period of use, the entity has both of the following: (a) the right to obtain substantially all of the economic benefits from use of the identified asset; and (b) the right to direct the use of the identified asset. The Company leases office and research facilities and office equipment under operating leases which expire at various dates through 2028. The Company’s leases have remaining lease terms of one year to ten 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 on the balance sheet; the Company recognizes lease expense for these leases on a straight-line basis over the lease term. 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. The Company uses its incremental borrowing rate for purposes of discounting lease payments. Lease cost is summarized in the table below (in thousands): Three Months Ended Six Months Ended June 30, 2019 June 30, 2018 June 30, 2019 June 30, 2018 Operating lease cost (1) $ 2,054 $ 1,795 $ 4,005 $ 3,629 (1) Includes short-term leases and variable lease costs, which were immaterial.

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 and six months ended June 30, 2019. For detail, refer to “Note 15 – Commitments and Contingencies” 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. Tessera, Inc. v. Toshiba Corporation, Civil Action No. 5:15-cv-02543-BLF (N.D. Cal.) On May 12, 2015, Tessera, Inc. filed a complaint against Toshiba Corporation (“Toshiba”) in California Superior Court. Tessera, Inc.’s complaint alleges causes of action for breach of contract, breach of the implied covenant of good faith and fair dealing, and declaratory relief, generally alleging that Toshiba underpaid royalties and failed to cooperate with audits conducted pursuant to the parties’ license agreement. On June 8, 2015, Toshiba removed the action to the U.S. District Court for the Northern District of California. On June 18, 2015, Toshiba filed its answer, affirmative defenses, and counterclaims to Tessera, Inc.’s complaint. Toshiba alleges counterclaims for declaratory judgment and breach of the implied warranty of good faith and fair dealing. The counterclaims seek, among other things, judicial determinations about the interpretation of the parties’ agreement, termination of the agreement, an accounting of the amount of alleged overpayments by Toshiba, restitution, and damages. On July 10, 2015, Tessera, Inc. filed its answer and affirmative defenses to Toshiba’s counterclaims. On March 17, 2016, Tessera, Inc. filed an amended complaint adding a claim for declaratory relief regarding a February 12, 2016 letter sent by Toshiba to Tessera, Inc. purporting to terminate the parties’ license agreement. On March 18, 2016, Toshiba filed its amended answer, affirmative defenses, and counterclaims. On April 4, 2016, Tessera, Inc. filed an answer to Toshiba’s amended counterclaims. An initial summary judgment hearing on contract issues took place on September 22, 2016. On November 7, 2016, the Court entered an order granting Toshiba’s motion regarding the definition of “TCC,” and denying summary judgment on the other issues raised by the parties’ cross-motions. On December 6, 2016, Tessera, Inc. filed a motion pursuant to Federal Rule of Civil Procedure 54(b) seeking authorization to appeal the order and for a stay. On March 6, 2017, the Court granted the Rule 54(b) motion. The Court subsequently vacated the trial date and stayed the remainder of the district court proceedings. On April 4, 2017, Tessera, Inc. filed a notice of appeal to the U.S. Court of Appeals for the Ninth Circuit. The parties completed briefing on November 2, 2017. A hearing for oral argument took place on October 15, 2018. On November 21, 2018, the Ninth Circuit dismissed the appeal for lack of appellate jurisdiction and remanded the case to the district court for further proceedings. The parties have both filed second round motions for summary judgment, and Toshiba has filed a motion to strike two of Tessera’s expert reports. All three motions are set to be heard on August 22, 2019 . Trial is set for October 19, 2020. Other Litigation Matters 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 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, including the Company’s The Semiconductor and IP Licensing segment develops and licenses semiconductor technologies and IP to manufacturers, foundries, subcontract assemblers and others. The segment includes revenue generated from the technology and IP portfolios of Tessera, Inc., Invensas and Invensas Bonding Technologies, Inc. (formerly Ziptronix, Inc.). Tessera, Inc. pioneered chip-scale packaging solutions. Invensas develops advanced semiconductor packaging and 3D interconnect solutions, including wafer and die bonding solutions, for applications such as smartphones, tablets, laptops, PCs, data centers and automobiles. The Company expands its technology and IP offerings in this segment through a combination of internal R&D and acquisitions. The Company also provides engineering services to customers in the form of technology demonstrations and technology transfers to assist their evaluation and adoption of the Company’s 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 and six months ended June 30, 2019 and 2018 (in thousands): Three Months Ended Six Months Ended June 30, 2019 June 30, 2018 June 30, 2019 June 30, 2018 Revenue: Product Licensing segment $ 61,431 $ 51,161 $ 105,999 $ 104,377 Semiconductor and IP Licensing segment 13,684 12,793 25,683 25,109 Total revenue 75,115 63,954 131,682 129,486 Operating expenses: Product Licensing segment 45,508 42,142 91,265 86,036 Semiconductor and IP Licensing segment 9,270 18,942 19,508 38,369 Unallocated operating expenses (1) 28,653 30,476 59,222 65,178 Total operating expenses 83,431 91,560 169,995 189,583 Operating income (loss): Product Licensing segment 15,923 9,019 14,734 18,341 Semiconductor and IP Licensing segment 4,414 (6,149 ) 6,175 (13,260 ) Unallocated operating expenses (1) (28,653 ) (30,476 ) (59,222 ) (65,178 ) Total operating loss $ (8,316 ) $ (27,606 ) $ (38,313 ) $ (60,097 ) (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.

Accounting Policies [Abstract]
Basis of Accounting	The accompanying interim unaudited condensed consolidated financial statements as of June 30, 2019 and 2018, and for the three and six 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, 2018 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, 2018, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018, filed on February 20, 2019 (the “Form 10-K”).
Recent Accounting Pronouncements	Recently Adopted Accounting Pronouncements In June 2018, the Financial Accounting Standards Board (“FASB”) issued Stock-based Compensation: Improvements to Nonemployee Share-based Payment Accounting,” In February 2016, the FASB issued ASU No. 2017-12, “ Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, In February 2016, the FASB issued ASU No. 2016-02, " Leases modified retrospective transition approach and elected the transition option The Company elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed it to carry forward the historical lease classification. Under the optional transition method, the Company opted to continue to apply the legacy guidance in ASC 840, Leases, including its disclosure requirements, in the comparative periods presented in the year it adopted the new leases standard, and therefore did not restate prior period results. The most significant impact from adopting Topic 842 was the initial recognition of operating lease ROU assets and operating lease liabilities of $17.6 million and $18.8 million, respectively, as of January 1, 2019. Operating lease liabilities consist of both current and noncurrent portions with the current portion included in the balance of accrued liabilities. The standard did not materially impact the Company’s Condensed Consolidated Statements of Operations and had no impact on cash flows. The cumulative effect of the changes made to the Company's Condensed Consolidated Balance Sheet as of January 1, 2019 for the adoption of Topic 842 was as follows (in thousands): Balance at December 31, 2018 Adjustments due to Topic 842 Balance at January 1, 2019 Assets Operating lease right-of-use assets $ — $ 17,594 $ 17,594 Liabilities Accrued liabilities $ 45,336 $ 3,858 (1) $ 49,194 Noncurrent operating lease liabilities $ — $ 13,736 $ 13,736 (1) Consists of a debit adjustment of $1.2 million to deferred rent to eliminate the existing balance and a credit adjustment of $5.1 million to record the current portion of operating lease liabilities. Recent Accounting Pronouncements In September 2016, the FASB issued ASU No. 2016-13, “ Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments
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 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 that 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. 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. Practical Expedients The Company expenses sales commissions when incurred because the amortization period generally would have been one year or less. In addition, sales commissions have historically not been a significant expense and are not contemplated to be significant in the future. Sales commissions are recorded in selling, general and administrative expenses in the Condensed Consolidated Statements of Operations.
