Organization, Consolidation and Presentation of Financial Statements [Abstract]
Background and Nature of Operations	Background and Nature of Operations Clarivate Plc (“Clarivate,” “us,” “we,” “our,” or the “Company”), is a public limited company organized under the laws of Jersey, Channel Islands. We were initially registered on January 7, 2019, and at our 2020 annual general meeting, our shareholders approved a change of our corporate name from “Clarivate Analytics Plc” to “Clarivate Plc”. Pursuant to the definitive agreement entered into to effect a merger between Camelot Holdings (Jersey) Limited ("Jersey") and Churchill Capital Corp, a Delaware corporation, ("Churchill") (the “2019 Transaction”), the Company was formed for the purposes of completing the 2019 Transaction and related transitions and carrying on the business of Jersey and its subsidiaries. The Company is a provider of proprietary and comprehensive content, analytics, professional services and workflow solutions that enable users across government and academic institutions, life science companies and research and development (“R&D”) intensive corporations to discover, protect and commercialize their innovations. Clarivate has two reportable segments: Science and Intellectual Property ("IP"). Our segment structure is organized to address customer needs by product line. Our Science segment consists of our Academic and Life Sciences Product Lines. Both provide curated, high-value, structured information that is delivered and embedded into the workflows of our customers, which include research intensive corporations, life science organizations and universities world-wide. Our IP segment consists of our Patent, Trademark, Domain and IP Management Product Lines. These Product Lines help manage customer's end-to-end portfolios of intellectual property from patents to trademarks to corporate website domains. See Note 21 - Segment Information, for additional information on the Company's reportable segments. In January 2019, we entered into an Agreement and Plan of Merger (as amended by Amendment No. 1 to the Agreement and Plan of Merger, dated February 26, 2019, and Amendment No. 2 to the Agreement and Plan of Merger, dated March 29, 2019, collectively, the “Merger Agreement”) by and among Churchill, Jersey, CCC Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of Clarivate (“Delaware Merger Sub”), Camelot Merger Sub (Jersey) Limited, a private limited company organized under the laws of Jersey, Channel Islands and wholly owned subsidiary of Clarivate (“Jersey Merger Sub”), and the Company, which, among other things, provided for (i) Jersey Merger Sub to be merged with and into Jersey with Jersey being the surviving company in the merger (the “Jersey Merger”) and (ii) Delaware Merger Sub to be merged with and into Churchill with Churchill being the surviving corporation in the merger (the “Delaware Merger”), and together with the Jersey Merger, the “Mergers”. On May 13, 2019, the 2019 Transaction was consummated, and Clarivate became the sole managing member of Jersey, operating and controlling all of the business and affairs of Jersey, through Jersey and its subsidiaries. Following the consummation of the 2019 Transaction on May 13, 2019, the Company’s ordinary shares and warrants began trading on the New York Stock Exchange. All of the Company’s public warrants have subsequently been redeemed. See Note 16 - Shareholders’ Equity for further information regarding the redemption of the Company’s public warrants. The 2019 Transaction was accounted for as a reverse recapitalization in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). Under this method of accounting, Churchill was treated as the "acquired" company for financial reporting purposes. This determination was primarily based on post 2019 Transaction relative voting rights, composition of the governing board, size of the two entities pre-merger, and intent of the 2019 Transaction. Accordingly, for accounting purposes, the 2019 Transaction was treated as the equivalent of the Company issuing stock for the net assets of Churchill. The net assets of Churchill were stated at historical cost, with no goodwill or other intangible assets resulting from the 2019 Transaction. Reported amounts from operations included herein prior to the 2019 Transaction are those of Jersey.

Risks and Uncertainties In March 2020, the World Health Organization characterized COVID-19 as a pandemic. The rapid spread of COVID-19 and the continuously evolving responses to combat it have had an increasingly negative impact on the global economy. In view of the rapidly changing business environment, market volatility and heightened degree of uncertainty resulting from COVID-19, we are currently unable to fully determine its future impact on our business. However, we continue to assess the potential effect on our financial position, results of operations, and cash flows. If the global pandemic continues to evolve into a prolonged crisis, the effects could have an adverse impact on the Company's results of operations, financial condition and cash flows.
