Organization, Consolidation and Presentation of Financial Statements [Abstract]
The Company and Basis of Presentation	NOTE 1 – THE COMPANY AND BASIS OF PRESENTATION Adeia Inc. (formerly known as Xperi Holding Corporation) (the "Company"), a Delaware corporation, is one of the industry’s largest intellectual property ("IP") licensing platforms, with a diverse portfolio of media and semiconductor intellectual property and more than 9,750 patents and patent applications worldwide. On December 18, 2019, Xperi Corporation (“Xperi”) entered into an Agreement and Plan of Merger and Reorganization with TiVo Corporation (“TiVo”) to combine in an all-stock merger of equals transaction (the “Mergers”). Immediately following the consummation of the Mergers on June 1, 2020 (the “Merger Date”), Xperi Holding Corporation, a Delaware corporation founded in December 2019 under the name “XRAY-TWOLF HoldCo Corporation,” became the parent company of both Xperi and TiVo. The common stock of Xperi and TiVo were de-registered after completion of the Mergers. On June 2, 2020, Xperi Holding Corporation’s common stock, par value $0.001 per share, commenced trading on the Nasdaq Global Select Market (“Nasdaq”) under the ticker symbol “XPER.” On October 1, 2022, the Company completed the previously announced separation ("the Separation") of its product business into a separate, independent, publicly-traded company, Xperi Inc. ("Xperi Inc."). The Separation was structured as a spin-off (the "Spin-off"), which was achieved through the Company's distribution of 100 percent of the outstanding shares of Xperi Inc.'s common stock to holders of the Company's common stock as of the close of business on the record date of September 21, 2022 (the "Record Date"). Each Company stockholder of record received four shares of Xperi Inc. common stock for every ten shares of Company common stock that it held on the Record Date. Following the Separation, the Company retains no ownership in Xperi Inc., which is now listed under the ticker symbol "XPER" on the New York Stock Exchange. Effective at the open of business on October 3, 2022, the Company's shares of common stock, par value $0.001 per share, began trading on the Nasdaq Global Select Market under the new ticker symbol "ADEA". The accounting requirements for reporting the Separation of Xperi Inc. as a discontinued operation were met when the Separation was completed. Accordingly, the financial results of Xperi Inc. for the years ended December 31, 2022, 2021 and 2020 are presented as net loss from discontinued operations, net of tax on the Consolidated Statements of Operations and its assets and liabilities as of December 31, 2021 are reclassified as discontinued operations in the Consolidated Balance Sheets. For further information on discontinued operations, see "Note 9 - Discontinued Operations". Unless noted otherwise, discussion in the Notes to the Consolidated Financial Statements pertain to continuing operations. Additionally, as a result of the Separation, the Company changed its operational structure in the fourth quarter of 2022, resulting in one reportable segment: Intellectual Property ("IP") Licensing. The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles (“GAAP”) in the United States (“U.S.”) and the applicable rules and regulations of the Securities and Exchange Commission (“SEC”). All intercompany balances and transactions are eliminated in consolidation. The Company's fiscal year ends on December 31. The Company employs a calendar month-end reporting period for its quarterly reporting. Reclassification Certain reclassifications have been made to prior period balances in order to conform to the current period’s presentation.
