SIGNIFICANT ACCOUNTING POLICIES	Dec. 31, 2022
Accounting Policies [Abstract]
SIGNIFICANT ACCOUNTING POLICIES	SIGNIFICANT ACCOUNTING POLICIES Description of Business Immersion Corporation (the "Company", "Immersion", "we" or "us") was incorporated in 1993 in California and reincorporated in Delaware in 1999. We focus on the creation, design, development, and licensing of innovative haptic technologies that allow people to use their sense of touch more fully as they engage with products and experience the digital world around them. We have adopted a business model that provides advanced tactile software, related tools, technical assistance designed to help integrate our patented technology into our customers’ products or enhance the functionality of our patented technology to certain customers, and offers licenses to our patented technology to other customers. Impact of COVID-19 The outbreak of coronavirus ("COVID-19") caused governments and public health officials around the world to implementing stringent measures to help control the spread of the virus. In response to the COVID-19 pandemic, we implemented work-from-home and restricted travel policies in the first quarter of 2020, but have since lifted our travel restriction and our employees now work both from the office and from home. In April 2020, the Government of Canada announced the Canada Emergency Wage Subsidy (“CEWS”) for Canadian employers whose businesses were affected by the COVID-19 pandemic. The CEWS provides a subsidy of up to 75% of eligible employees’ employment insurable remuneration, subject to certain criteria. We applied for the CEWS to the extent we met the requirements to receive the subsidy. During the year ended December 31, 2021 we recognized $0.3 million in government subsidies as a reduction to operating expenses in the Consolidated Statements of Income and Comprehensive Income . We did not recognize for any government subsidy during the year ended December 31, 2022. Principles of Consolidation and Basis of Presentation The accompanying consolidated financial statements include the accounts of Immersion and our wholly-owned subsidiaries. All intercompany accounts, transactions, and balances have been eliminated in consolidation. Certain prior year amounts have been reclassified to conform with the current year presentation. Use of Estimates The preparation of consolidated financial statements in conformity with the generally accepted accounting principles in the United States ("GAAP") requires estimates and assumptions that affect the amounts reported in the consolidated financial statements and the accompanying notes. Actual results may differ materially from these estimates On an ongoing basis, we evaluate our estimates, including those related to revenue recognition, fair value of financial instruments, property and equipment, income taxes, contingent liabilities, long-term deposits for withholding taxes and stock-based compensation. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Foreign Currency Translation The functional currency of our foreign subsidiaries is U.S. dollars. Gains and losses from the remeasurement financial statements of the foreign subsidiaries into the U.S. dollars and from foreign currency transaction are reported as Other income (expense), net in our Consolidated Statements of Income and Other Comprehensive Income . Revenue Recognition Our revenue is primarily derived from fixed fee license agreements and per-unit royalty agreements, along with less significant revenue earned from development, services and other revenue. Fixed fee license revenue We recognize revenue from a fixed fee license agreement when we have satisfied our performance obligations, which typically occurs upon the transfer of rights to our technology upon the execution of the license agreement. However, in certain contracts, we grant a license to our existing patent portfolio at the inception of the license agreement as well as rights to the portfolio as it evolves throughout the contract term. For such arrangements, we have concluded that there are two separate performance obligations: • Performance Obligation A: Transfer of rights to our patent portfolio as it exists when the contract is executed; • Performance Obligation B: Transfer of rights to our patent portfolio as it evolves over the term of the contract, including access to new patent applications that the licensee can benefit from over the term of the contract. If a fixed fee license agreement contains only Performance Obligation A, we recognize the revenue from the agreement at the inception of the contract. For fixed fee license agreements that contain both Performance Obligation A and B, we allocate the transaction price based on the standalone price for each of the two performance obligations. We use a number of factors primarily related to the attributes of our patent portfolio to estimate standalone prices related to Performance Obligation A and B. Once the transaction price is allocated, the portion of the transaction price allocable to Performance Obligation A is recognized in the period the license agreement is signed and the customer can benefit from rights provided in the contract. The portion allocable to Performance Obligation B is recognized on a straight-line basis over the contract term which best represents the ongoing and continuous nature of the patent prosecution process. For such contracts, a contract liability account is established and included within Deferred revenue on the Consolidated Balance Sheet s. As the rights and obligations in a contract are interdependent, contract assets and contract liabilities that arise in the same contract are presented on a net basis. Some of our license agreements contain fixed fees related to past infringements. Such fixed fees are recognized as revenue or recorded as a deduction to our operating expense in the quarter the license agreement is signed. Payments for fixed fee license contracts typically are due in full within 30 - 45 days from execution of the contract. From time to time, we enter into a fixed fee license contract with payments due in a number of installments payable throughout the contract term. In such cases, we determine if a significant financing component exists and if it does, we will recognize more or less revenue and corresponding interest expense or income, as appropriate. Per-unit Royalty revenue We record per-unit royalty revenue in the same period in which the licensee’s underlying sales occur. When we do not receive the per-unit licensee royalty reports for sales during a given quarter within the time frame that allows us to adequately review the reports and include the actual amounts in our quarterly results for such quarter, we accrue the related revenue based on estimates of our licensees’ underlying sales, subject to certain constraints on our ability to estimate such amounts. We develop such estimates based on a combination of available data including, but not limited to, approved customer forecasts, a look back at historical royalty reporting for each of our customers, and industry information available for the licensed products. As a result of accruing per-unit royalty revenue for the quarter based on such estimates, adjustments will be required in the following quarter to true up revenue to the actual amounts reported by its licensees. In 2022, we recorded $0.3 million, $0.5 million and $0.5 million adjustments to increase royalty revenue in the first, second and fourth quarters, respectively. In the third quarter of 2022, we recorded adjustments of $0.2 million to decrease royalty revenue. In 2021, we recorded $0.5 million, $0.5 million and $0.1 million adjustments to decrease royalty revenue in the first, third and fourth quarters, respectively. In the second quarter of 2021, we recorded adjustments of $2.0 million to increase royalty revenue. Certain of our per-unit royalty agreements contain minimum royalty provisions which sets forth minimum amounts to be received by us during the contract term. Under Accounting Standard Codification 606, Revenue from Contracts with Customers , (“ASC 606”), minimum royalties are considered a fixed transaction price to which we have a right once all other performance obligations, if any, are satisfied. We recognize all minimum royalties as revenue at the inception of the license agreement, or in the period in which all remaining revenue recognition criteria have been met. We account for the unbilled minimum royalties as contract assets as Prepaid and other current assets and Other assets, net on our Consolidated Balance Sheets , and the balance of such contract assets will be reduced by the actual royalties to be reported by the licensee during the contract term until fully utilized, after which point any excess per-unit royalties reported are recognized as revenue. As the rights and obligations in a contract are interdependent, contract assets and contract liabilities that arise in the same contract are presented on a net basis. Payments of per-unit royalties typically are due within 30 to 60 days from the end of the quarter in which the underlying sales took place. Development, services, and other revenue As the performance obligation related to our development, service and other revenue is satisfied over a period of time, we recognize such revenue evenly over the period of performance obligations, which is generally consistent with the contractual term. Deferred Revenue Deferred revenue consists of amounts that have been invoiced or paid, but have not been recognized as revenue. The amounts are primarily derived from our fixed license fee agreements under which we are obliged to transfer both rights to our patent portfolio that exists when the contract is executed and rights to its patent portfolio as it evolves over the contract term. Deferred revenue that will be recognizable during the succeeding 12-month period is recorded as Deferred Revenu e- current , and the remaining deferred revenue is recorded as D eferred revenue noncurrent on the Consolidated Balance Sheets . Capitalized Contract Costs We capitalize certain incremental costs incurred, such as commissions, in order to obtain new contracts with our customers if we expect to recover these costs. The capitalized contract costs are amortized on a straight-line basis over the term of the contract. Fair Value Measurement We measure the fair value of financial assets as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. We use the GAAP fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. This hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The three levels of the fair value hierarchy are as follows: Level 1 — Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 — O bservable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3 — Unobservable inputs for the asset or liability, which include assumptions market participants would use in pricing the asset or liability. Cash Equivalents We consider all highly liquid instruments with an original or remaining maturity of 90 days or less at the date of purchase to be cash equivalents. Certificates of deposit Certificate of deposits are reported at fair value and classified as current or noncurrent assets based on their initial and remaining maturity days at purchase. Certificates of deposit with original or remaining maturity days of 90 days or less are reported as cash equivalents, between 91 days and 1 year are reported as Investment- current . Certificates of deposit with longer than 1-year remaining term are reported as Investments - noncurrent on the Consolidated Balance Sheets . Investments in Marketable Securities Equity Securities We hold marketable equity investments over which we do not have a controlling interest or significant influence. Our investments in marketable equity securities are classified based on the nature of the securities and their availability for use in current operations. As of December 31, 2022, our marketable equity securities primarily consisted of mutual funds and corporate common and preferred stocks. Marketable equity investments are reported as Investment-current on the Consolidated Balance Sheets . They are measured using quoted prices in active markets with changes recorded in Other income (expense), net on the Consolidated Statements of Income and Other Comprehensive Income. Debt Securities Debt securities primarily consist of investments in corporate bonds and U.S. treasury securities. Our investments in marketable debt securities have been classified and accounted for as available-for-sale. We report our marketable debt securities as either Investments-current or Investments-noncurrent on our Consolidated Balance Sheets based on each instrument’s underlying contractual maturity date and management's intended holding period. Unrealized gains and losses on marketable debt securities classified as available-for-sale are recognized as Other comprehensive income (loss) on the Consolidated Statements of Income and Comprehensive Income . We may sell certain marketable debt securities prior to their stated maturities for reasons including, but not limited to, managing liquidity, credit risk, duration and asset allocation. If quoted prices for identical instruments are available in an active market, debt securities are classified within Level 1 of the fair value hierarchy. If quoted prices for identical instruments in active markets are not available, fair values are estimated using quoted prices of similar instruments and are classified within Level 2 of the fair value hierarchy. To date, all of our debt securities can be valued using one of these two methodologies. Derivative Financial Instruments We invest in derivatives that are not designated as hedging instruments and which consist of call and put options. When we sell call or put options, the premium received is reported as Other current liabilities on our Consolidated Balance Sheets . When we purchase put or call options, the premium paid is reported as Investments-current on our Consolidated Balance Sheets . The carrying value of these options is adjusted to the fair value, measured using the practical expedient of the midpoint of the bid-ask spread, at the end of each reporting period until the options expire. Gains and losses recognized from the periodic adjustments to fair value are recognized as Interest and other income (loss ), net on our Consolidated Statements of Income and Comprehensive Income . Accounts and Other Receivables Accounts and other receivables are primarily comprised of trade receivables that are recorded at the invoice amount, net of an allowance for credit losses. We assess our allowance for credit losses on trade receivables by taking into consideration forecasts of future economic conditions, information about past events, such as our historical trend of write-offs, and customer-specific circumstances, such as bankruptcies and disputes. The allowance for credit losses on trade receivables is recorded in operating expenses on our Consolidated Statements of Income and Comprehensive Income . Property and Equipment, Net Property and equipment are stated at cost less accumulated depreciation. Depreciation is recorded using straight-line method over the estimated useful life of the related assets. Property and equipment is reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. The estimated useful lives are typically as follows: Computer equipment and purchased software 3 years Machinery and equipment 3-5 years Furniture and fixtures 5 years Leasehold improvements are amortized over the shorter of the lease term or their estimated useful life. Total depreciation expenses for property and equipment for years ended December 31, 2022, and 2021 were $0.1 million and $0.1 million, respectively. Leases We lease our office space under lease arrangements with expiration dates on or before April 25, 2024. Operating leases are accounted for as right-of-use (“ROU”) assets and lease liability obligations in our Consolidated Balance Sheets under Other assets , net, Other current liabilities and Other long-term liabilities , respectively. ROU assets and lease liabilities are recognized at lease commencement date based on the present value of lease payments over the lease term. We elect to combine lease and non-lease components and account for them as a single lease component. As our leases typically do not provide an implicit rate, we estimate our incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. ROU assets also include any lease payments made and exclude lease incentives and direct costs. Lease expense is recognized on a straight-line basis over the lease term. We elected to not present leases with an initial term of 12 months or less on our Consolidated Balance Sheets . Variable lease payments primarily include reimbursements of costs incurred by lessors for common area maintenance and utilities and are expensed as incurred and are not included within the ROU asset and lease liability calculation. Advertising Advertising costs are expensed as incurred. Advertising expenses for the years ended December 31, 2022, and 2021 were zero and $0.2 million, respectively. Research and Development Research and development expenses primarily consisted of personnel-related costs, including payroll and stock-based compensation, outside consulting expenses and allocations of corporate overhead expenses. Research and development costs are expensed as incurred. Legal Proceedings and Litigations We are involved in legal proceedings on an ongoing basis. If we believe that a loss arising from such matters is probable and can be reasonably estimated, we accrue the estimated loss in our Consolidated Financial Statement s. If only a range of estimated losses can be determined, we accrue an amount within the range that, in our judgment, reflects the most likely outcome; if none of the estimates within that range is a better estimate than any other amount, we accrue the low end of the range. Patent Defense Costs Costs associated with patent applications, patent prosecution, patent defense and the maintenance of patents are charged to expense as incurred. Income Taxes We use the asset and liability method of accounting for income taxes. Under this method, income tax expense is recognized for the amount of taxes payable or refundable for the current year. In addition, deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities, and for operating losses and tax credit carryforwards. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized and are reversed at such a time that realization is believed to be more-likely-than-not. Stock-based Compensation We recognize stock-based compensation cost for shares, net of estimated forfeiture over the requisite service period of the award, which is the vesting period. We use the Black-Scholes Merton option pricing model to determine the fair value of stock options and employee stock purchase plan shares. We estimate the fair value of market-performance based stock options and restricted stock units using a Monte Carlo simulation model which requires the input of assumptions, including expected term, stock price volatility and the risk-free rate of return. In addition, judgment is also required in estimating the number of stock-based awards that are expected to be forfeited. Forfeitures are estimated based on historical experience at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Concentrations of Credit Risk and Significant Customers Our financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents, marketable securities, and accounts and other receivables. Deposits held by banks may exceed the amount of insurance provided on such deposits. Generally, these deposits may be redeemed upon demand. We are subject to a concentration of revenues given certain key licensees that contributed a significant portion of our total revenues. See Note 12. Segment Reporting, Geographic Information and Significant Customers of the Notes to Consolidated Financial Statements for more details on customer revenue concentration. We license technology primarily to companies in North America, Europe, and Asia. To reduce credit risk, management performs periodic credit evaluations of the financial conditions of our customer. We periodically evaluate potential credit losses to ensure adequate reserves are maintained, but historically we have not experienced any significant losses related to individual customers or groups of customers in any particular industry or geographic area. As such, our reserves for credit losses for the years ended December 31, 2022 and December 31, 2021 were not material due to our low credit risk. Certain Significant Risks and Uncertainties We operate in multiple industries and our operations can be affected by a variety of factors. For example, management believes that changes in any of the following areas could have a negative effect on our future financial position and results of operations: the impact of COVID-19 on our business, and the impact of COVID-19 on our customers, suppliers, and on the economy in general; our strategy and our ability to execute our business plan; our competition and the market in which we operate; our customers and suppliers; our revenue, trends related thereto and the recognition and components thereof; our costs and expenses; including capital expenditures; our investment of surplus funds and sales of marketable securities ; seasonality and demand; our investment in research and technology development; changes to general and administrative expenses; our foreign operations and the reinvestment of our earnings related thereto; our investment in and protection of our IP; our employees; capital expenditures and the sufficiency of our capital resources; unrecognized tax benefit and tax liabilities; the impact of changes in interest rates and foreign exchange rates, as well as our plans with respect to foreign currency hedging in general; changes in laws and regulations; including with respect to taxes; our plans related to and the impact of current and future litigation and arbitration; our sublease and the timing and income related thereto; and our stock repurchase and equity distribution programs and equity distribution programs. Segment Information We operate as one operating segment because our Chief Executive Officer, as our chief operating decision maker, reviews financial information, on a consolidated basis for purposes of making decisions regarding allocating resources and assessing performance. Our chief operating decision maker (“CODM”) is the Chief Executive Officer. The CODM approves budgets and allocates resources to and assesses our business performance using information about our revenue and operating loss. There is only one segment that is reported to management. Recently Adopted Accounting Pronouncements In November 2021, Financial Accounting Standard Board ("FASB") issued ASU 2021-10, Government Assistance (Topic 832) , which requires annual disclosures that increase the transparency of transactions involving government grants, including the types of transactions, the accounting for those transactions, and the effect of those transactions on an entity’s financial statements. This new standard became effective for annual periods beginning after December 15, 2021. We adopted this new guidance in the first quarter of 2022. This adoption did not have a material impact on our consolidated financial statements.

Contract assets decreased by $2.0 million from January 1, 2021 to December 31, 2021, primarily due to actual royalties billed during the year. Deferred Revenue Based on contracts signed and payments received as of December 31, 2022, we expect to recognize $17.4 million in revenue related to Performance Obligation B under our fixed fee license agreements, which are satisfied over time, including $11.7 million over one to three years and $5.7 million over more than three years. As of December 31, 2021, total deferred revenue was $21.5 million. In 2022, we recorded a $0.8 million increase in deferred revenue as a result to a new contract with a customer.

Investments, Debt and Equity Securities [Abstract]
INVESTMENTS AND FAIR VALUE MEASUREMENTS	INVESTMENTS AND FAIR VALUE MEASUREMENTS Marketable Securities We invest surplus funds in excess of operational requirements in a diversified portfolio of marketable securities, with the objectives of delivering competitive returns, maintaining a high degree of liquidity, and seeking to avoid the permanent impairment of principal. We regularly review our investment portfolio to identify and evaluate investments that have indicators of possible impairment. Investments are considered impaired when a decline in fair value is judged to be other-than-temporary. If the cost of an individual investment exceeds its fair value, we evaluate, among other factors, general market conditions, the duration and extent to which the fair value is less than cost, and our intent and ability to hold the investment. Once a decline in fair value is determined to be other-than-temporary, we will record an impairment charge and establish a new cost basis for the investment. Marketable securities as of December 31, 2022, and December 31, 2021, consisted of the following (in thousands): December 31, 2022 Cost or Amortized Cost Unrealized Gains Unrealized Losses Fair Value Mutual funds $ 26,352 $ — $ (3,143) $ 23,209 U.S. treasury securities 25,640 182 (24) 25,798 Corporate bonds 13,496 48 (106) 13,438 Equity securities 53,273 2,776 (5,836) 50,213 $ 118,761 $ 3,006 $ (9,109) $ 112,658 December 31, 2021 Cost or Amortized Cost Unrealized Gains Unrealized Losses Fair Value Mutual funds $ 50,000 $ — $ (338) $ 49,662 Corporate bonds 6,996 290 — 7,286 Equity securities 38,100 — (1,331) 36,769 $ 95,096 $ 290 $ (1,669) $ 93,717 As of December 31, 2022, and December 31, 2021, marketable securities are as follows (in thousands): December 31, 2022 Marketable Equity Securities Marketable Debt Securities Total Mutual funds $ 23,209 $ — $ 23,209 U.S. treasury securities — 25,798 25,798 Equity securities 50,213 — 50,213 Corporate bonds — 13,438 13,438 $ 73,422 $ 39,236 $ 112,658 December 31, 2021 Marketable Equity Securities Marketable Debt Securities Total Mutual funds $ 49,662 $ — $ 49,662 Equity securities 36,769 — 36,769 Corporate bonds — 7,286 7,286 $ 86,431 $ 7,286 $ 93,717 The amortized costs and fair value of marketable debt securities, by contractual maturity, as of December 31, 2022 (in thousands) are as follows: December 31, 2022 Amortized Fair Less than 1 year $ 22,014 $ 22,196 1 to 5 years 12,086 11,973 More than 5 years 5,036 5,067 Total $ 39,136 $ 39,236 Derivative Financial Instruments Our derivative instruments consisted of call and put options sold at their fair value as of the balance sheet date.

Equity securities are classified within Level 1 of the fair value hierarchy as they are valued based on quoted market price in an active market. Corporate debt securities and derivative instruments are valued based on quoted prices in markets that are less active, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency are generally classified within Level 2 of the fair value hierarchy. Financial instruments valued based on unobservable inputs which reflect the reporting entity’s own assumptions or data that market participants would use in valuing an instrument are generally classified within Level 3 of the fair value hierarchy. We did not hold Level 3 financial instruments as of December 31, 2022, and December 31, 2021. Financial instruments measured at fair value on a recurring basis as of December 31, 2022, and December 31, 2021 are classified based on the valuation technique in the table below (in thousands): December 31, 2022 Fair Value Measurements Using Quoted Prices Significant Significant Total Assets: Certificates of deposit $ — $ 5,300 $ — $ 5,300 U.S. treasury securities — 25,798 — 25,798 Mutual funds 23,209 — — 23,209 Equity securities 50,213 — — 50,213 Corporate bonds — 13,438 — 13,438 Total assets at fair value $ 73,422 $ 44,536 $ — $ 117,958 Liabilities Derivative instruments $ — $ 3,649 $ — $ 3,649 Total liabilities at fair value $ — $ 3,649 $ — $ 3,649 December 31, 2021 Fair Value Measurements Using Quoted Prices Significant Significant Total Assets: Mutual funds $ 49,662 $ — $ — 49,662 Equity securities 36,769 — — 36,769 Corporate bonds — 7,286 — 7,286 Total assets at fair value $ 86,431 $ 7,286 $ — $ 93,717 Liabilities Derivative instruments $ — $ 6,267 $ — $ 6,267 Total liabilities at fair value $ — $ 6,267 $ — $ 6,267 If quoted prices for identical instruments are available in an active market, debt securities are classified within Level 1 of the fair value hierarchy.

Commitments and Contingencies Disclosure [Abstract]
CONTINGENCIES	CONTINGENCIESFrom time to time, we receive claims from third parties asserting that our technologies, or those of our licensees, infringe on the other parties’ IP rights. Management believes that these claims are without merit. Additionally, periodically, we are involved in routine legal matters and contractual disputes incidental to our normal operations. In management’s opinion, unless we disclosed otherwise, the resolution of such matters will not have a material adverse effect on our consolidated financial condition, results of operations, or liquidity. In the normal course of business, we provide indemnification of varying scope to customers, most commonly to licensees in connection with licensing arrangements that include our IP, although these provisions can cover additional matters. Historically, costs related to these guarantees have not been significant, and we are unable to estimate the maximum potential impact of these guarantees on its future results of operations. Samsung Electronics Co. v. Immersion Corporation and Immersion Software Ireland Limited On April 28, 2017, Immersion and Immersion Software Ireland Limited (collectively referred to as “Immersion” in this section) received a letter from Samsung Electronics Co. (“Samsung”) requesting that we reimburse Samsung with respect to withholding tax and penalties imposed on Samsung by the Korean tax authorities following an investigation where the tax authority determined that Samsung failed to withhold taxes on Samsung’s royalty payments to Immersion Software Ireland from 2012 to 2016. On July 12, 2017, on behalf of Samsung, Immersion filed an appeal with the Korea Tax Tribunal regarding their findings with respect to the withholding taxes and penalties. On September 29, 2017, Samsung filed an arbitration demand with the International Chamber of Commerce against us demanding that we reimburse Samsung for the imposed tax and penalties that Samsung paid to the Korean tax authorities. Samsung requested that we pay Samsung the amount of KRW7,841,324,165 (approximately $6.9 million) plus interest from and after May 2, 2017, plus the cost of the arbitration including legal fees. On October 18, 2018, the Korea Tax Tribunal held a hearing and on November 19, 2018, the Korea Tax Tribunal issued its ruling in which it decided not to accept our arguments with respect to the Korean tax authorities’ assessment of withholding tax and penalties imposed on Samsung. On behalf of Samsung, we filed an appeal with the Korea Administrative Court on February 15, 2019. On March 27, 2019, we received the final award relating to the arbitration demand that Samsung had filed on September 29, 2017. The award ordered Immersion to pay Samsung KRW7,841,324,165 (approximately $6.9 million as of March 31, 2019), which we paid on April 22, 2019, denied Samsung’s claim for interest from and after May 2, 2017; and ordered Immersion to pay Samsung’s cost of the arbitration in the amount of approximately $871,454, which was paid in 2019. On July 16, 2020, the Korea Administrative Court issued its ruling in which it ruled that the withholding taxes and penalties which were imposed by the Korean tax authorities on Samsung should be cancelled with some litigation costs to be borne by the Korean tax authorities. On August 1, 2020, the Korean tax authorities filed an appeal with the Korea High Court. The first hearing in the Korea High Court occurred on November 11, 2020. A second hearing occurred on January 13, 2021. A third hearing occurred on March 21, 2021. The Korea High Court had indicated that a final decision was originally expected on May 28, 2021, but instead, decided to hold a fourth hearing on July 9, 2021. On October 1, 2021, the Korea High Court issued its ruling in which it ruled that withholding taxes and penalties totaling approximately KRW6,186,218,586 (approximately $5.2 million) in national-level withholding tax and local withholding taxes imposed by the Korean tax authorities on Samsung for royalties paid to Immersion during the period of 2012 – 2014 be cancelled on the basis that the Korea tax authorities wrongfully engaged in a duplicative audit with respect to such time period. The Korea High Court also ruled that approximately KRW1,655,105,584 (approximately$1.4 million) of national-level withholding tax and local withholding taxes imposed by the Korean tax authorities on Samsung for royalties paid to Immersion during 2015 and 2016 be upheld in part on the basis that Immersion Software Ireland Limited did not have sufficient economic substance to be considered the beneficial owner of the royalties paid by Samsung to Immersion Software Ireland Limited. On or about October 22, 2021, the Korean tax authorities filed an appeal with the Korea Supreme Court with respect to certain portions of the Korea High Court decision and we filed an appeal with the Korea Supreme Court with respect to certain portions of the Korea High Court decision. On December 1, 2021, the Korean tax authorities submitted its brief to the Korea Supreme Court challenging the cancellation by the Korea High Court of a portion of the withholding tax imposed by the Korean tax authorities. On December 3, 2021, we submitted our own brief to the Korea Supreme Court providing arguments in support of our position that Immersion Software Ireland Limited has sufficient economic substance to be considered the beneficial owner of the royalties paid by Samsung to Immersion Software Ireland Limited. Such brief also provided arguments challenging the calculation of the imposed withholding tax upheld by the Korea High Court. On December 2021, the Korean tax authorities filed a rebuttal brief relating to our brief filed on December 3, 2021. On December 29, 2021, we filed our rebuttal brief relating to the Korean tax authorities’ brief filed on December 1, 2021. On February 24, 2022, the Korea Supreme Court issued a decision affirming the rulings of the Korea High Court. We believe that any impairment in the Long-term deposits associated with the rulings of the Korea High Court was appropriately reflected in the Consolidated Balance Sheets . In the fourth quarter of 2021, we recorded an impairment charge of $1.4 million related to long-term deposits paid to Samsung. In March 2022, as a result of the Korea Supreme Court decision described above, we were reimbursed by Samsung in an amount equal to KRW6,088,855,388 (approximately $5 million) representing Korea national-level taxes, penalties and interest that were canceled by the Korea Supreme Court, which amount is net of $1.3 million of the impairment charge previously recorded in the fourth quarter of 2021. We were also reimbursed an additional KRW608,885,000 (approximately $0.5 million) representing local-level taxes, penalties and interest that were canceled by the Korea Supreme Court, which amount is net of $0.1 million of the impairment charge previously recorded in the fourth quarter of 2021. LGE Korean Withholding Tax Matter On October 16, 2017, we received a letter from LG Electronics Inc. (“LGE”) requesting that we reimburse LGE with respect to withholding tax imposed on LGE by the Korean tax authorities following an investigation where the tax authority determined that LGE failed to withhold on LGE’s royalty payments to Immersion Software Ireland from 2012 to 2014. Pursuant to an agreement reached with LGE, on April 8, 2020, we provided a provisional deposit to LGE in the amount of KRW 5,916,845,454 (approximately $5.0 million) representing the amount of such withholding tax that was imposed on LGE, which provisional deposit would be returned to us to the extent we ultimately prevail in the appeal in the Korea courts. In the second quarter of 2020, we recorded this deposit in Long-term deposits on our Consolidated Balance Sheets . In the event that we do not ultimately prevail in our appeal in the Korean courts, the deposit included in Long-term deposits would be recorded as additional income tax expense on our Consolidated Statements of Income and Comprehensive Income, in the period in which we do not ultimately prevail. On November 3, 2017, on behalf of LGE, we filed an appeal with the Korea Tax Tribunal regarding their findings with respect to the withholding taxes. The Korea Tax Tribunal hearing took place on March 5, 2019. On March 19, 2019, the Korea Tax Tribunal issued its ruling in which it decided not to accept our arguments with respect to the Korean tax authorities’ assessment of withholding tax and penalties imposed on LGE. On behalf of LGE, we filed an appeal with the Korea Administrative Court on June 10, 2019. The first hearing occurred on October 15, 2019. A second hearing occurred on December 19, 2019. A third hearing occurred on February 13, 2020. A fourth hearing occurred on June 9, 2020. A fifth hearing occurred on July 16, 2020. We anticipated a decision to be rendered on or about October 8, 2020, but the Korea Administrative Court scheduled and held a sixth hearing for November 12, 2020. A seventh hearing occurred on January 14, 2021. An eighth hearing occurred on April 8, 2021. A ninth hearing occurred on June 24, 2021. A tenth hearing occurred on September 13, 2021. An eleventh hearing occurred on November 15, 2021. A twelfth hearing occurred on December 23, 2021. The Court had indicated that it expected to render a decision on this matter by the end of February 2022. However, due to a reshuffling of judges, another hearing, which was originally scheduled for April 14, 2022, occurred on July 7, 2022. A thirteenth hearing occurred on October 27, 2022. A fourteenth hearing occurred November 24, 2022. The Court had indicated that it expected to render a decision on this matter by December 31, 2022, but had subsequently updated the parties to indicate that a decision on this matter is expected by February 16, 2023. On February 15, 2023, we were informed that the Court had scheduled another hearing for April 27, 2023. Based on the developments in these cases, we regularly reassess the likelihood that we will prevail in the claims from the Korean tax authorities with respect to the LGE case. To the extent that we determine that it is more likely than not that we will prevail against the claims from the Korean tax authorities, then no additional tax expense is provided for in our Consolidated Statements of Income and Comprehensive Income . In the event that we determine that it is more likely than not that we will not prevail against the claims from the Korean tax authorities, or a portion thereof, then we would estimate the anticipated additional tax expense associated with that outcome and record it as additional income tax expense in our Consolidated Statements of Income and Comprehensive Income in the period of the new determination. If the additional income tax expense was related to the periods assessed by Korean tax authorities and for which we recorded a Long-term deposits on our Consolidated Balance Sheets , then the additional income tax expense would be recorded as an impairment to the Long-term deposits . If the additional income tax expense was not related to the periods assessed by Korean tax authorities and for a which we recorded in Long-term deposits on our Consolidated Balance Sheets , then the additional income tax expense would be accrued as an Other current liabilities . In the event that we do not ultimately prevail in our appeal in the Korean courts with respect to this case, the applicable deposits included in Long-term deposits would be recorded as additional income tax expense on our Consolidated Statements of Income and Comprehensive Income , in the period in which we do not ultimately prevail. In the fourth quarter of 2021, we recorded an impairment charge of $0.8 million related to the long-term deposits paid to LGE. Immersion Software Ireland Limited v. Marquardt GMBH On August 3, 2021, we filed an arbitration demand with the American Arbitration Association (the “AAA”) against Marquardt GmbH (“Marquardt”), one of our licensees in the automotive market. The arbitration demand had arisen out of that certain Amended and Restated Patent License Agreement (the “Marquardt License”), effective as of January 1, 2018, between us as licensor and Marquardt, as licensee. Pursuant to the arbitration demand, we demanded that Marquardt cure its breach of the Marquardt License and pay all royalties currently owed under the Marquardt License. Pursuant to the terms of the Marquardt License, we requested arbitration by a single arbitrator in Madison County, New York. On August 9, 2021, the AAA confirmed receipt of our arbitration demand dated August 3, 2021. On August 13, 2021, the AAA conducted an administrative conference call to discuss communications, mediation, tribunal appointment, place of arbitration, and other administrative topics. On September 15, 2021, Marquardt filed an answer to our arbitration demand with the AAA, in which Marquardt provided general denials of our claims and asserted a counterclaim for approximately $138,000 in royalties previously paid to us under the Marquardt License. On September 30, 2021, we filed an answer to Marquardt’s counterclaim in which we denied the allegations set forth in Marquardt’s counterclaim. A preliminary hearing occurred on December 6, 2021, during which the parties agreed to explore mediation and the arbitrator set forth a schedule relating to the arbitration. A mediation session occurred during the period of March 14-16, 2022. At the mediation, we entered into a binding settlement term sheet with Marquardt pursuant to which we agreed to cause our arbitration demand to be dismissed. In exchange, Marquardt agreed to the prepayment of certain royalties otherwise payable under the Marquardt License. Additionally on April 4, 2022, we entered into an amendment to the Marquardt License to reflect such payment and other related terms. On May 20, 2022, the parties submitted a stipulation of dismissal to the AAA dismissing with prejudice all claims brought by us against Marquardt in the arbitration. Immersion Corporation vs. Meta Platforms, Inc., f/k/a Facebook, Inc. On May 26, 2022, we filed a complaint against Meta Platforms, Inc. (formerly known as Facebook, Inc.) (“Meta”) in the United States District Court for the Western District of Texas. The complaint alleges that Meta’s augmented and virtual reality (“AR/VR”) systems, including the Meta Quest 2, infringe six of our patents that cover various uses of haptic effects in connection with such AR/VR systems. We are seeking to protect Meta from further infringement and to recover a reasonable royalty for such infringement. The complaint against Meta asserts infringement of the following patents: • U.S. Patent No. 8,469,806: “System and method for providing complex haptic stimulation during input of control gestures, and relating to control of virtual equipment” • U.S. Patent No. 8,896,524: “Context-dependent haptic confirmation system” • U.S. Patent No. 9,727,217: “Haptically enhanced interactivity with interactive content” • U.S. Patent No. 10,248,298: “Haptically enhanced interactivity with interactive content” • U.S. Patent No. 10,269,222: “System with wearable device and haptic output device” • U.S. Patent No. 10,664,143: “Haptically enhanced interactivity with interactive content” Meta responded to our complaint on August 1, 2022. On September 12, 2022, Meta filed a motion to transfer the lawsuit to the Northern District of California or, in the alternative, to the Austin Division of the Western District of Texas. Meta’s motion remains pending, and a hearing on the transfer motion occurred on January 23, 2023. In the meantime, claim construction briefing is closed, and fact discovery opened on February 7, 2023. The claim construction hearing is scheduled for March 6, 2023.

Under our equity incentive plans, stock options may be granted at prices not less than the fair market value on the date of the grant for stock options. Stock options generally vest over four years and expire seven A summary of our equity incentive program as of December 31, 2022, is as follows (in thousands): Common stock shares available for grant 631 Stock options outstanding 140 RSUs outstanding 887 RSAs outstanding 119 PSUs outstanding 615 Time-Based Stock Options The following summarizes activities for the time-based stock options for the year ended December 31, 2022: Number of Shares Weighted Average Weighted Average Aggregate Outstanding at December 31, 2021 242 $ 8.04 4.44 $ — Granted — — Exercised — — Canceled or expired (102) 8.55 Outstanding as of December 31, 2022 140 $ 7.67 4.03 $ — Vested and expected to vest at December 31, 2022 137 $ 7.67 4.03 $ — Exercisable at December 31, 2022 102 $ 7.66 4.02 $ — The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying awards and the exercise price of our common stock for the options that were in-the-money.

Participants may not purchase more than 2,000 shares in a six-month offering period or purchase stock having a value greater than $25,000 in any calendar year as measured at the beginning of the offering period. A total of 1.0 million shares of common stock had been reserved for issuance under the ESPP. During the year ended December 31, 2022, 11,416 shares were purchased under the ESPP. As of December 31, 2022, 194,432 shares were available for future purchase under the ESPP. Effective February 1, 2023, our ESPP program was discontinued. Stock-based Compensation Expense Valuation and amortization methods Stock-based compensation is based on the estimated fair value of awards, net of estimated forfeitures, and recognized over the requisite service period. Estimated forfeitures are based on historical experience at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The stock-based compensation related to all of our stock-based awards and ESPP for the year ended December 31, 2022, and 2021 is as follows (in thousands): Years Ended 2022 2021 Stock options $ 120 $ 386 RSUs, RSAs and PSUs 3,295 1,894 ESPP 2 58 Total $ 3,417 $ 2,338 Sales and marketing $ 61 $ 745 Research and development 117 742 General and administrative 3,239 851 Total $ 3,417 $ 2,338 As of December 31, 2022, there was $8.6 million of unrecognized compensation cost adjusted for estimated forfeitures related to non-vested stock options, RSUs, RSAs and PSUs granted to our employees and directors. This unrecognized compensation cost will be recognized over an estimated weighted-average period of approximately 2.1 years. Total unrecognized compensation cost will be adjusted for future changes in estimated forfeitures.

Equity [Abstract]
STOCKHOLDERS' EQUITY	STOCKHOLDERS’ EQUITY Stock Repurchase Agreement On February 14, 2022, we entered into a Common Stock Repurchase Agreement (the “Agreement”) with Invenomic Capital Management LP. (“Invenomic”). P ursuant to the Agreement, we purchased 904,499 shares of our common stock from Invenomic at $4.725 per share, or an aggregate purchase price of $4.3 million. The closing price of our common stock on February 14, 2022 was $4.80 per share. We adopted a Section 382 Tax Benefits Preservation Plan on November 17, 2021 to diminish the risk we could experience an “ownership change” as defined in Section 382 of the Internal Revenue Code of 1986, as amended, which could substantially limit or permanently eliminate our ability to utilize its net operating loss carryovers to reduce potential future income tax obligations. Under this plan, a person who acquires, without the approval of our Board of Directors, beneficial ownership of 4.99% or more of the outstanding common stock could be subject to significant dilution. Following the repurchase, Invenomic’s holdings dropped to below 4.99% of the outstanding common stock. Stock Repurchase Program On February 23, 2022, our Board of Directors (the "Board") approved a stock repurchase program of up to $30.0 million of our common stock for a period of up to twelve months (the "February 2022 Stock Repurchase Program"). Any stock repurchases may be made through open market and privately negotiated transactions, at such times and in such amounts as management deems appropriate, including pursuant to one or more Rule 10b5-1 trading plans adopted in accordance with Rule 10b5-1 of the Securities Exchange Act of 1934. Additionally, the Board authorized the use of any derivative or similar instrument to effect stock repurchase transactions, including without limitation, accelerated share repurchase contracts, equity forward transactions, equity option transactions, equity swap transactions, cap transactions, collar transactions, naked put options, floor transactions or other similar transactions or any combination of the foregoing transactions. The stock repurchase program was implemented as a method to return value to our stockholders. The timing, pricing and sizes of any repurchases will depend on a number of factors, including the market price of our common stock and general market and economic conditions. The stock repurchase program does not obligate us to repurchase any dollar amount or number of shares, and the program may be suspended or discontinued at any time. The February 2022 Stock Repurchase Program was terminated on December 29, 2022. In the year ended December 31, 2022, we repurchased 1,637,566 shares of our common stock for $8.9 million at an average purchase price of $5.46 per share. The February 2022 Stock Repurchase Program was terminated on December 29, 2022. On December 29, 2022, the Board approved a stock repurchase program of up to $50.0 million of our common stock for a period of up to twelve months (the "December 2022 Stock Repurchase Program"), which terminated and superseded the stock repurchase program that had been approved by our Board of Directors on February 23, 2022. Any stock repurchases may be made through open market and privately negotiated transactions, at such times and in such amounts as management deems appropriate, including pursuant to one or more Rule 10b5-1 trading plans adopted in accordance with Rule 10b5-1 of the Securities Exchange Act of 1934. Additionally, the Board authorized the use of any derivative or similar instrument to effect stock repurchase transactions, including without limitation, accelerated share repurchase contracts, equity forward transactions, equity option transactions, equity swap transactions, cap transactions, collar transactions, naked put options, floor transactions or other similar transactions or any combination of the foregoing transactions. The stock repurchase program was implemented as a method to return value to our stockholders. The timing, pricing and sizes of any repurchases will depend on a number of factors, including the market price our common stock and general market and economic conditions. The stock repurchase program does not obligate us to repurchase any dollar amount or number of shares, and the program may be suspended or discontinued at any time. As of December 31, 2022, we have $50.0 million available for repurchase under the December 2022 Stock Repurchase Program. Dividends Payment On November 14, 2022, our Board of Directors ("Board") declared a quarterly dividend in the amount of $0.03 per share, which was paid on January 30, 2023, to stockholders of record on January 15, 2023. In addition, on December 29, 2022, our Board declared a special dividend in the amount of $0.10 per share, which was paid on January 30, 2023 to stockholders of record on January 15, 2023. On February 21, 2023, our Board declared a second quarterly dividend, in the amount of $0.03 per share, which will be paid on April 28, 2023 to stockholders of record on April 13, 2023.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES Benefit from (provision for) income taxes the years ended December 31, 2022 and 2021 consisted of the following (in thousands): Years Ended 2022 2021 Income before benefit from (provision for) income taxes 26,965 17,290 Benefit from (provision for) income taxes 3,699 (4,806) Effective tax rate (13.7) % 27.8 % Benefit from income taxes for the year ended December 31, 2022, resulted primarily from estimated domestic and foreign taxes included in the calculation of the effective tax rate. Provision for income taxes for the year ended December 31, 2021 primarily consisted of estimated U.S. taxes, adjustments to uncertain tax positions withholding tax reserve, foreign taxes and foreign withholding taxes. We put a partial valuation allowance for certain federal assets and continue to maintain full valuation allowance for state and certain foreign deferred tax assets in the United States and Canada. The components of our income before benefit from (provision for) income taxes were as follows (in thousands): Years Ended 2022 2021 Domestic $ 14,552 $ 5,893 Foreign 12,413 11,397 Total $ 26,965 $ 17,290 The benefit from (provision for) income taxes consisted of the following (in thousands): Years Ended December 31, 2022 2021 Current: U.S. federal $ 458 $ 3,285 States and local 74 2 Foreign 871 934 Total current 1,403 4,221 Deferred: U.S. federal (5,694) — States and local — — Foreign 592 585 Total deferred (5,102) 585 Total benefit from (provision for) income taxes $ (3,699) $ 4,806 Deferred tax assets and liabilities are recognized for the temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes, tax losses, and credit carryforwards. Significant components of the net deferred tax assets and liabilities consisted of (in thousands): December 31, 2022 2021 Deferred tax assets: Net operating loss carryforwards $ 5,391 $ 7,638 State income taxes 15 1 Deferred revenue 3,498 4,502 Research and development and other credits 3,757 10,493 Reserve and accruals recognized in different periods 1,692 395 Capitalized research and development expenses 3,019 3,333 Depreciation and amortization 1,802 2,492 Lease liability 104 339 Total deferred tax assets 19,278 29,193 Valuation allowance (12,341) (27,239) Net deferred tax assets 6,937 1,954 Deferred tax liabilities: Right of use lease assets (67) (185) Foreign credits — — Other deferred tax liabilities — — Total deferred tax liabilities (67) (185) Net deferred taxes $ 6,870 $ 1,769 We account for deferred taxes under ASC 740 which requires a reduction of the carrying amounts of deferred tax assets by a valuation allowance if, based on available evidence, it is more likely than not that such assets will not be realized. Accordingly, the need to establish valuation allowances for deferred tax assets is assessed periodically based on the ASC 740 more-likely-than-not realization ("MLTN") threshold criterion. This assessment considers matters such as future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. The evaluation of the recoverability of the deferred tax assets requires that we weigh all positive and negative evidence to reach a conclusion that it is more likely than not that all or some portion of the deferred tax assets will not be realized. The weight given to the evidence is commensurate with the extent to which it can be objectively verified. As of December 31, 2022, based on our assessment of the realizability of our deferred tax assets, we put partial valuation allowance for certain federal assets, whose future realization is not more likely than not and continue to maintain full valuation allowance for state and certain foreign deferred tax assets in the United States and Canada. As of December 31, 2022, the net operating loss carryforwards for federal and state income tax purposes were approximately $12.0 million and $53.0 million, respectively. The state net operating losses begin to expire in 2029. The federal net operating losses for tax years after 2017 can be carried forward indefinitely. We have no net operating loss carryforward from foreign jurisdictions. As of December 31, 2022, we had federal and state tax credit carryforwards of approximately $3.2 million and $2.5 million, respectively, available to offset future tax liabilities. The federal credit carryforwards will expire between 2023 and 2039 and the California tax credits will carryforward indefinitely. In addition, as of December 31, 2022, we have Canadian research and development credit carryforwards of $1.8 million, which will expire at various dates through 2040. These operating losses and credit carryforwards have not been reviewed by the relevant tax authorities and could be subject to adjustment upon examinations. Section 382 of the Internal Revenue Code (“IRC Section 382”) imposes limitations on a corporation’s ability to utilize its net operating losses and credit carryforwards if it experiences an “ownership change” as defined by IRC Section 382. Utilization of a portion of our federal net operating loss carryforward was limited in accordance with IRC Section 382, due to an ownership change that occurred during 1999. This limitation has fully lapsed as of December 31, 2010. As of December 31, 2022, we conducted an IRC Section 382 analysis with respect to our net operating loss and credit carryforwards and determined there was no limitation. There can be no assurance that future issuances of our securities will not trigger limitations under IRC Section 382 which could limit utilization of these tax attributes. The reconciliation of federal statutory income tax rate to our effective tax rate was as follows (in thousands): Years Ended 2022 2021 Federal statutory rate 21.0 % 21.0 % Foreign withholding 0.3 % 0.4 % Stock-based compensation expense 0.3 % 0.6 % Foreign rate differential (2.3) % (7.9) % Prior year true-up items (0.9) % 0.1 % Tax reserves 5.3 % (2.3) % Loss on expiration of capital loss carryover — % — % FTC 1.4 % — % Other 0.7 % 2.7 % FTC conversion true up — % (11.1) % 2017 Tax Act impact — % — % State taxes, net of federal benefit 0.2 % — % Global intangible low-taxed income 6.4 % 9.7 % Nondeductible officers compensation 1.1 % — % Irish corporation restructure — % — % Valuation allowance (47.2) % 14.6 % Effective tax rate (13.7) % 27.8 % The undistributed earnings of our foreign subsidiaries are considered to be indefinitely reinvested and accordingly, no provision for applicable income taxes has been provided thereon. Upon distribution of those earnings, we are subject to withholding taxes payable to various foreign countries. As of December 31, 2022, any foreign withholding taxes on the undistributed earnings of our foreign subsidiaries were immaterial. We maintain liabilities for uncertain tax positions. These liabilities involve considerable judgment and estimation and are continuously monitored by management based on the best information available, including changes in tax regulations, the outcome of relevant court cases, and other information. A reconciliation of the beginning and ending amount of gross unrecognized tax benefits is as follows (in thousands): Years Ended 2022 2021 Balance at beginning of year 7,569 4,525 Gross increases for tax positions of prior years (2,170) 1 Gross decreases for federal tax rate change for tax positions of prior years 647 — Gross increases for tax positions of current year 1,146 3,296 Settlements — — Lapse of statute of limitations (99) (253) Balance at end of year 7,093 7,569 The unrecognized tax benefits relate primarily to federal and state research and development credits, intercompany profit on the transfer of certain IP rights to one of our foreign subsidiaries as part of our tax reorganization completed in 2015 and withholding tax reserve. Based on our assessment of the developments in the Samsung case (South Korea withholding taxes) in October of 2021, we provided for an additional income tax expense of $0.3 million in 2022. We also settled $1.4 million previously accrued Samsung case liability in 2022. We account for interest and penalties related to uncertain tax positions as a component of income tax expense. As of December 31, 2021, we accrued $0.1 million interest or penalties related to uncertain tax positions. As of December 31, 2022, the total amount of unrecognized tax benefits that would affect our effective tax rate, if recognized, was $0. Because we have net operating loss and credit carryforwards, there are open statutes of limitations in which federal, state and foreign taxing authorities may examine our tax returns for all years from 2008 through the current period.

NET INCOME (LOSS) PER SHARE	Dec. 31, 2022
Earnings Per Share [Abstract]
NET INCOME (LOSS) PER SHARE	NET INCOME (LOSS) PER SHARE Basic net income (loss) per share is computed using the weighted average number of shares of common stock outstanding during the period. Diluted net income (loss) per share is computed using the weighted average number of shares of common stock, adjusted for any dilutive effect of potential common stock. Potential common stock, computed using the treasury stock method, includes stock options, stock awards and ESPP. The following is a reconciliation of the denominators used in computing basic and diluted net income (loss) per share (in thousands, except per share amounts): Years Ended 2022 2021 Denominator: Weighted-average shares outstanding, basic 33,280 31,459 Shares related to outstanding options, unvested RSUs, RSAs, PSUs and ESPP 228 310 Weighted average shares outstanding, diluted 33,508 31,769 We include market condition-based performance restricted stock units in the calculation of diluted earnings per share if the performance condition has been satisfied as of the end of the reporting period and exclude stock equity awards if the performance condition has not been met. For the years ended December 31, 2022, and 2021, we had stock options, RSUs, PSUs and RSAs outstanding that could potentially dilute basic earnings per share in the future, but these were excluded from the computation of diluted net income per share because their effect would have been anti-dilutive. These outstanding securities consisted of the following (in thousands): Years Ended 2022 2021 Stock options 184 225 Restricted stock units, restricted stock awards and market condition-based restricted stock units 25 — Total 209 225

Leases with an initial term of 12 months or less are not recorded on the Consolidated Balance Sheets . We combine lease and non-lease components for new and reassessed leases. We apply discount rates to operating leases using a portfolio approach.

This sublease commenced on June 8, 2022 and ends on February 27, 2024 which approximates the lease termination date of the original Montreal Facility lease. In accordance with provisions of ASC 842, we treated the sublease as a separate lease as we were not relieved of the primary obligation under the original lease. We continue to account for the original Montreal Facility, as a lessee, in the same manner as prior to the commencement date of the sublease. We accounted for the sublease as a lessor of the lease. We classified the sublease as an operating lease as it did not meet the criteria of a Sale-Type or Direct Financing lease. At the commencement date of the sublease, we recognized initial direct costs of $23,000. These deferred costs will be amortized over the term of the sublease payments. On January 31, 2022, we entered into an agreement to lease a 1,390 square feet of office space in Aventura, Florida (“Aventura Lease”). We use this facility as our principal executive offices and for general administrative functions. This lease commenced in the first quarter of 2022 and expires in the first quarter of 2024. We accounted for this lease as an operating lease in accordance with the provisions of ASC 842 Leases (“ASC 842”). In the first quarter of 2022, we recorded a lease liability of $0.1 million, which represents the present value of the lease payments using an estimated incremental borrowing rate of 3.93%. We also recognized a right-to-use asset ("ROU") of $0.1 million which represents our right to use an underlying asset for the lease term. On March 12, 2020, we entered into a sublease agreement with Neato Robotics, Inc. (“Neato”) for our facility located in San Jose, California (the "San Jose Facility"). This sublease commenced in June 2020 and ends on April 30, 2023 which is the lease termination date of the original San Jose Facility lease. In accordance with provisions of ASC 842, we treated the sublease as a separate lease as we were not relieved of the primary obligation under the original lease. We continue to account for the original San Jose Facility, as a lessee, in the same manner as prior to the commencement date of the sublease. We accounted for the sublease as a lessor of the lease. We classified the sublease as an operating lease as it did not meet the criteria of a Sale-Type or Direct Financing lease. At the commencement date of the sublease, we recognized initial direct costs of $0.3 million. These deferred costs will be amortized over the term of the sublease payments. As of December 31, 2022, the unamortized balance of the deferred costs are not material. We recognize operating lease expense and lease payments from the sublease, on a straight-line basis, in our Consolidated Statements of Income and Comprehensive Income over the lease terms. During the year ended December 31, 2022, and 2021, our net operating lease expenses are as follows (in thousands): Years Ended 2022 2021 Operating lease costs $ 906 $ 834 Variable lease payments 426 399 Sublease income (1,143) (1,030) Total lease cost (income) $ 189 $ 203 Minimum future lease payments obligations as of December 31, 2022, are as follows (in thousands): For the Years Ending December 31, 2023 $ 594 2024 39 Total lease payments 633 Less: Interest (91) Total lease liability $ 542 Future cash receipts from our sublease agreements as of December 31, 2022, are as follows (in thousands): For the Years Ending December 31, 2023 $ 550 2024 33 Total $ 583

Accounting Policies [Abstract]
Principles of Consolidation	The accompanying consolidated financial statements include the accounts of Immersion and our wholly-owned subsidiaries. All intercompany accounts, transactions, and balances have been eliminated in consolidation.
Basis of Presentation	Certain prior year amounts have been reclassified to conform with the current year presentation.
Use of Estimates	Use of EstimatesThe preparation of consolidated financial statements in conformity with the generally accepted accounting principles in the United States ("GAAP") requires estimates and assumptions that affect the amounts reported in the consolidated financial statements and the accompanying notes. Actual results may differ materially from these estimates On an ongoing basis, we evaluate our estimates, including those related to revenue recognition, fair value of financial instruments, property and equipment, income taxes, contingent liabilities, long-term deposits for withholding taxes and stock-based compensation. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities.
Foreign Currency Translation	Foreign Currency Translation The functional currency of our foreign subsidiaries is U.S. dollars. Gains and losses from the remeasurement financial statements of the foreign subsidiaries into the U.S. dollars and from foreign currency transaction are reported as Other income (expense), net in our Consolidated Statements of Income and Other Comprehensive Income
Revenue Recognition	Revenue Recognition Our revenue is primarily derived from fixed fee license agreements and per-unit royalty agreements, along with less significant revenue earned from development, services and other revenue. Fixed fee license revenue We recognize revenue from a fixed fee license agreement when we have satisfied our performance obligations, which typically occurs upon the transfer of rights to our technology upon the execution of the license agreement. However, in certain contracts, we grant a license to our existing patent portfolio at the inception of the license agreement as well as rights to the portfolio as it evolves throughout the contract term. For such arrangements, we have concluded that there are two separate performance obligations: • Performance Obligation A: Transfer of rights to our patent portfolio as it exists when the contract is executed; • Performance Obligation B: Transfer of rights to our patent portfolio as it evolves over the term of the contract, including access to new patent applications that the licensee can benefit from over the term of the contract. If a fixed fee license agreement contains only Performance Obligation A, we recognize the revenue from the agreement at the inception of the contract. For fixed fee license agreements that contain both Performance Obligation A and B, we allocate the transaction price based on the standalone price for each of the two performance obligations. We use a number of factors primarily related to the attributes of our patent portfolio to estimate standalone prices related to Performance Obligation A and B. Once the transaction price is allocated, the portion of the transaction price allocable to Performance Obligation A is recognized in the period the license agreement is signed and the customer can benefit from rights provided in the contract. The portion allocable to Performance Obligation B is recognized on a straight-line basis over the contract term which best represents the ongoing and continuous nature of the patent prosecution process. For such contracts, a contract liability account is established and included within Deferred revenue on the Consolidated Balance Sheet s. As the rights and obligations in a contract are interdependent, contract assets and contract liabilities that arise in the same contract are presented on a net basis. Some of our license agreements contain fixed fees related to past infringements. Such fixed fees are recognized as revenue or recorded as a deduction to our operating expense in the quarter the license agreement is signed. Payments for fixed fee license contracts typically are due in full within 30 - 45 days from execution of the contract. From time to time, we enter into a fixed fee license contract with payments due in a number of installments payable throughout the contract term. In such cases, we determine if a significant financing component exists and if it does, we will recognize more or less revenue and corresponding interest expense or income, as appropriate. Per-unit Royalty revenue We record per-unit royalty revenue in the same period in which the licensee’s underlying sales occur. When we do not receive the per-unit licensee royalty reports for sales during a given quarter within the time frame that allows us to adequately review the reports and include the actual amounts in our quarterly results for such quarter, we accrue the related revenue based on estimates of our licensees’ underlying sales, subject to certain constraints on our ability to estimate such amounts. We develop such estimates based on a combination of available data including, but not limited to, approved customer forecasts, a look back at historical royalty reporting for each of our customers, and industry information available for the licensed products. As a result of accruing per-unit royalty revenue for the quarter based on such estimates, adjustments will be required in the following quarter to true up revenue to the actual amounts reported by its licensees. In 2022, we recorded $0.3 million, $0.5 million and $0.5 million adjustments to increase royalty revenue in the first, second and fourth quarters, respectively. In the third quarter of 2022, we recorded adjustments of $0.2 million to decrease royalty revenue. In 2021, we recorded $0.5 million, $0.5 million and $0.1 million adjustments to decrease royalty revenue in the first, third and fourth quarters, respectively. In the second quarter of 2021, we recorded adjustments of $2.0 million to increase royalty revenue. Certain of our per-unit royalty agreements contain minimum royalty provisions which sets forth minimum amounts to be received by us during the contract term. Under Accounting Standard Codification 606, Revenue from Contracts with Customers , (“ASC 606”), minimum royalties are considered a fixed transaction price to which we have a right once all other performance obligations, if any, are satisfied. We recognize all minimum royalties as revenue at the inception of the license agreement, or in the period in which all remaining revenue recognition criteria have been met. We account for the unbilled minimum royalties as contract assets as Prepaid and other current assets and Other assets, net on our Consolidated Balance Sheets , and the balance of such contract assets will be reduced by the actual royalties to be reported by the licensee during the contract term until fully utilized, after which point any excess per-unit royalties reported are recognized as revenue. As the rights and obligations in a contract are interdependent, contract assets and contract liabilities that arise in the same contract are presented on a net basis. Payments of per-unit royalties typically are due within 30 to 60 days from the end of the quarter in which the underlying sales took place. Development, services, and other revenue As the performance obligation related to our development, service and other revenue is satisfied over a period of time, we recognize such revenue evenly over the period of performance obligations, which is generally consistent with the contractual term. Deferred Revenue Deferred revenue consists of amounts that have been invoiced or paid, but have not been recognized as revenue. The amounts are primarily derived from our fixed license fee agreements under which we are obliged to transfer both rights to our patent portfolio that exists when the contract is executed and rights to its patent portfolio as it evolves over the contract term. Deferred revenue that will be recognizable during the succeeding 12-month period is recorded as Deferred Revenu e- current , and the remaining deferred revenue is recorded as D eferred revenue noncurrent on the Consolidated Balance Sheets . Capitalized Contract Costs
Fair Value Measurement	Fair Value Measurement We measure the fair value of financial assets as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. We use the GAAP fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. This hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The three levels of the fair value hierarchy are as follows: Level 1 — Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 — O bservable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3 — Unobservable inputs for the asset or liability, which include assumptions market participants would use in pricing the asset or liability.
Cash Equivalents and Certificates of deposit	Cash Equivalents We consider all highly liquid instruments with an original or remaining maturity of 90 days or less at the date of purchase to be cash equivalents. Certificates of deposit Certificate of deposits are reported at fair value and classified as current or noncurrent assets based on their initial and remaining maturity days at purchase. Certificates of deposit with original or remaining maturity days of 90 days or less are reported as cash equivalents, between 91 days and 1 year are reported as Investment- current . Certificates of deposit with longer than 1-year remaining term are reported as Investments - noncurrent on the Consolidated Balance Sheets .
Investments in Marketable Securities	Investments in Marketable Securities Equity Securities We hold marketable equity investments over which we do not have a controlling interest or significant influence. Our investments in marketable equity securities are classified based on the nature of the securities and their availability for use in current operations. As of December 31, 2022, our marketable equity securities primarily consisted of mutual funds and corporate common and preferred stocks. Marketable equity investments are reported as Investment-current on the Consolidated Balance Sheets . They are measured using quoted prices in active markets with changes recorded in Other income (expense), net on the Consolidated Statements of Income and Other Comprehensive Income. Debt Securities Debt securities primarily consist of investments in corporate bonds and U.S. treasury securities. Our investments in marketable debt securities have been classified and accounted for as available-for-sale. We report our marketable debt securities as either Investments-current or Investments-noncurrent on our Consolidated Balance Sheets based on each instrument’s underlying contractual maturity date and management's intended holding period. Unrealized gains and losses on marketable debt securities classified as available-for-sale are recognized as Other comprehensive income (loss) on the Consolidated Statements of Income and Comprehensive Income . We may sell certain marketable debt securities prior to their stated maturities for reasons including, but not limited to, managing liquidity, credit risk, duration and asset allocation. If quoted prices for identical instruments are available in an active market, debt securities are classified within Level 1 of the fair value hierarchy. If quoted prices for identical instruments in active markets are not available, fair values are estimated using quoted prices of similar instruments and are classified within Level 2 of the fair value hierarchy. To date, all of our debt securities can be valued using one of these two methodologies. Derivative Financial Instruments We invest in derivatives that are not designated as hedging instruments and which consist of call and put options. When we sell call or put options, the premium received is reported as Other current liabilities on our Consolidated Balance Sheets . When we purchase put or call options, the premium paid is reported as Investments-current on our Consolidated Balance Sheets . The carrying value of these options is adjusted to the fair value, measured using the practical expedient of the midpoint of the bid-ask spread, at the end of each reporting period until the options expire. Gains and losses recognized from the periodic adjustments to fair value are recognized as Interest and other income (loss ), net on our Consolidated Statements of Income and Comprehensive Income .
Accounts and Other Receivables	Accounts and Other Receivables Accounts and other receivables are primarily comprised of trade receivables that are recorded at the invoice amount, net of an allowance for credit losses. We assess our allowance for credit losses on trade receivables by taking into consideration forecasts of future economic conditions, information about past events, such as our historical trend of write-offs, and customer-specific circumstances, such as bankruptcies and disputes. The allowance for credit losses on trade receivables is recorded in operating expenses on our Consolidated Statements of Income and Comprehensive Income .
Property and Equipment, Net	Property and Equipment, Net Property and equipment are stated at cost less accumulated depreciation. Depreciation is recorded using straight-line method over the estimated useful life of the related assets. Property and equipment is reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. The estimated useful lives are typically as follows: Computer equipment and purchased software 3 years Machinery and equipment 3-5 years Furniture and fixtures 5 years Leasehold improvements are amortized over the shorter of the lease term or their estimated useful life.
Leases	Leases We lease our office space under lease arrangements with expiration dates on or before April 25, 2024. Operating leases are accounted for as right-of-use (“ROU”) assets and lease liability obligations in our Consolidated Balance Sheets under Other assets , net, Other current liabilities and Other long-term liabilities , respectively. ROU assets and lease liabilities are recognized at lease commencement date based on the present value of lease payments over the lease term. We elect to combine lease and non-lease components and account for them as a single lease component. As our leases typically do not provide an implicit rate, we estimate our incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. ROU assets also include any lease payments made and exclude lease incentives and direct costs. Lease expense is recognized on a straight-line basis over the lease term. We elected to not present leases with an initial term of 12 months or less on our Consolidated Balance Sheets
Advertising	AdvertisingAdvertising costs are expensed as incurred.
Research and Development	Research and DevelopmentResearch and development expenses primarily consisted of personnel-related costs, including payroll and stock-based compensation, outside consulting expenses and allocations of corporate overhead expenses. Research and development costs are expensed as incurred.
Legal Proceedings and Litigations	Legal Proceedings and Litigations We are involved in legal proceedings on an ongoing basis. If we believe that a loss arising from such matters is probable and can be reasonably estimated, we accrue the estimated loss in our Consolidated Financial Statement s. If only a range of estimated losses can be determined, we accrue an amount within the range that, in our judgment, reflects the most likely outcome; if none of the estimates within that range is a better estimate than any other amount, we accrue the low end of the range. Patent Defense Costs Costs associated with patent applications, patent prosecution, patent defense and the maintenance of patents are charged to expense as incurred.
Income Taxes	Income Taxes We use the asset and liability method of accounting for income taxes. Under this method, income tax expense is recognized for the amount of taxes payable or refundable for the current year. In addition, deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities, and for operating losses and tax credit carryforwards. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized and are reversed at such a time that realization is believed to be more-likely-than-not.
Stock-based Compensation	Stock-based CompensationWe recognize stock-based compensation cost for shares, net of estimated forfeiture over the requisite service period of the award, which is the vesting period. We use the Black-Scholes Merton option pricing model to determine the fair value of stock options and employee stock purchase plan shares. We estimate the fair value of market-performance based stock options and restricted stock units using a Monte Carlo simulation model which requires the input of assumptions, including expected term, stock price volatility and the risk-free rate of return. In addition, judgment is also required in estimating the number of stock-based awards that are expected to be forfeited. Forfeitures are estimated based on historical experience at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.
Concentration of Credit Risks	Concentrations of Credit Risk and Significant Customers Our financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents, marketable securities, and accounts and other receivables. Deposits held by banks may exceed the amount of insurance provided on such deposits. Generally, these deposits may be redeemed upon demand. We are subject to a concentration of revenues given certain key licensees that contributed a significant portion of our total revenues. See Note 12. Segment Reporting, Geographic Information and Significant Customers of the Notes to Consolidated Financial Statements for more details on customer revenue concentration.
Certain Significant Risks and Uncertainties	Certain Significant Risks and Uncertainties We operate in multiple industries and our operations can be affected by a variety of factors. For example, management believes that changes in any of the following areas could have a negative effect on our future financial position and results of operations: the impact of COVID-19 on our business, and the impact of COVID-19 on our customers, suppliers, and on the economy in general; our strategy and our ability to execute our business plan; our competition and the market in which we operate; our customers and suppliers; our revenue, trends related thereto and the recognition and components thereof; our costs and expenses; including capital expenditures; our investment of surplus funds and sales of marketable securities ;
Segment Information	Segment Information We operate as one operating segment because our Chief Executive Officer, as our chief operating decision maker, reviews financial information, on a consolidated basis for purposes of making decisions regarding allocating resources and assessing performance. Our chief operating decision maker (“CODM”) is the Chief Executive Officer. The CODM approves budgets and allocates resources to and assesses our business performance using information about our revenue and operating loss. There is only one segment that is reported to management.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements In November 2021, Financial Accounting Standard Board ("FASB") issued ASU 2021-10, Government Assistance (Topic 832) , which requires annual disclosures that increase the transparency of transactions involving government grants, including the types of transactions, the accounting for those transactions, and the effect of those transactions on an entity’s financial statements. This new standard became effective for annual periods beginning after December 15, 2021. We adopted this new guidance in the first quarter of 2022. This adoption did not have a material impact on our consolidated financial statements.
