Thomson Scientific was one of the five operating divisions of The Thomson Corporation from 2006 to 2008. Following the merger of Thomson with Reuters Group to form Thomson Reuters in 2008, it became the "Scientific" business unit of the new company. In 2009, the Scientific business came together with the Healthcare business to form the Healthcare & Science business of Thomson Reuters. The healthcare business was sold in 2012 and is now Truven Health Analytics. Prior to 2006 the two businesses were combined as Thomson Scientific & Healthcare. In late 2011, Thomson Reuters announced a new organizational structure, with one of its divisions being Intellectual Property & Science.
The Science unit of Thomson Reuters provided information-based solutions for the academic, business and R&D communities. It had headquarters in Philadelphia, London, Singapore and Tokyo with about 2,400 staff in more than 20 countries. The Science unit provided integrated information solutions with brands such as Aureka, Delphion, Cortellis, Derwent World Patents Index (DWPI), EndNote, Horizon Global, Horizon Sourcing, IDdb, IDRAC, IP Management Services, ISI Web of Knowledge, MicroPatent PatentWeb, Techstreet Industry Standards, ThomsonPharma, GeneGo, IDDB, Thomson Regulatory Solutions, and Web of Science. This science unit of Thomson Reuters (known as IP & Science unit) was sold in 2016 to Onex and Baring Private Equity Asia for $3.5 billion. The newly independent company has been named as Clarivate Analytics.
