Clarivate Plc is a British-American publicly traded analytics company that operates a collection of subscription-based services, in the areas of bibliometrics and scientometrics; business / market intelligence, and competitive profiling for pharmacy and biotech, patents, and regulatory compliance; trademark protection, and domain and brand protection.[3] In the academy and the scientific community, Clarivate is known for being the company that calculates the impact factor,[4] using data from its Web of Science product family, that also includes services/applications such as Publons, EndNote, EndNote Click, and ScholarOne. Its other product families are Cortellis, DRG, CPA Global, Derwent, CompuMark, and Darts-ip, [3] and also the various ProQuest products and services.

Clarivate was formed in 2016, following the acquisition of Thomson Reuters' Intellectual Property and Science business by Onex Corporation and Baring Private Equity Asia.[5] Clarivate has acquired various companies since then, including, notably, ProQuest in 2021.

Company history[edit]

Clarivate[6] was formerly the Intellectual Property and Science division of Thomson Reuters. Before 2008, it was known as Thomson Scientific.[7] In 2016, Thomson Reuters struck a $3.55 billion deal in which they spun it off as an independent company, and sold it to private-equity firms Onex Corporation and Baring Private Equity Asia.[8][9]

In May 2019, Clarivate merged with the Churchill Capital Corp SPAC to obtain a public listing on the New York Stock Exchange (NYSE)[10] It currently trades with symbol NYSE:CLVT.[11][12]

After the 2022 Russian invasion of Ukraine, on March 11, 2022, Clarivate, which has an office in Odesa, Ukraine announced that it would cease all commercial activity in Russia.[13]


As of 2023, the company conducts operations through three strategic business units: Intellectual Property Group, Life Sciences & Healthcare Group, and Academic and Government Group, each led by a president.[14][15]

Clarivate has been criticized for its anti-competitive practices in a highly oligopolistic academic database market, for increasing the prices of the products it acquired, for the lack of further development and integration of the acquired products, for not developing its own products, for outsourcing jobs from the US and UK to India, and for eliminating telephone support for many of the acquired products.[16][17]

Leadership Changes[edit]

On July 11, 2022, Clarivate announced that Jerre Stead would retire from his role as Executive Chair and Chief Executive Officer to become Non-Executive Chair of the Board of Directors on September 1, 2022. Jonathan Gear, previously Chief Financial Officer of IHS Markit, joined Clarivate on July 11, 2022, as CEO-elect, and became Chief Executive Officer on September 1, 2022.[18] [19]

On September 1, 2022, Clarivate announced that Jerre Stead would retire from the Board on October 20, 2022, at which date Andrew Snyder, CEO of Cambridge Information Group and Vice Chairman of Clarivate, becomes the new Chair effective from that date. The Board has appointed Stead as Chairman Emeritus upon his Board retirement.[1]

  • December 1, 2021: ProQuest, software, data and analytics provider to academic, research and national institutions.[28] It was acquired for $5.3 billion from Cambridge Information Group in what was described as a "huge deal in the library and information publishing world". The company said that the operational concept behind the acquisition was integrating ProQuest's products and applications with Web of Science.[29] Chairman of ProQuest Andy Snyder became the vice chairman of Clarivate.[30] The Scholarly Publishing and Academic Resources Coalition, an advocacy group for open access to scholarship, voiced antitrust concerns.[28] The acquisition had been delayed mid-year due to a Federal Trade Commission antitrust probe.[31]


Products and services[edit]

Web of Science[edit]

The Web of Science (WoS; previously known as Web of Knowledge) is a paid-access platform that provides (typically via the internet) access to multiple databases that provide reference and citation data from academic journals, conference proceedings, and other documents in various academic disciplines. Until 1997, it was originally produced by the Institute for Scientific Information.[34] It is currently owned by Clarivate,[35] and currently contains 79 million records in the core collection and 171 million records on the platform.[36]

The Web of Science Core Collection consists of six online indexing databases:[37][38]

  • Science Citation Index Expanded (SCIE), previously entitled Science Citation Index, covers more than 9,200 journals across 178 scientific disciplines. Coverage is from 1900 to present day, with over 53 million records[39]
  • Social Sciences Citation Index (SSCI) covers more than 3,400 journals in the social sciences. Coverage is from 1900 to present, with over 9.3 million records[40]
  • Arts & Humanities Citation Index (AHCI) covers more than 1,800 journals in the arts and humanities. Coverage is from 1975 to present, with over 4.9 million records[41]
  • Emerging Sources Citation Index (ESCI) covers more than 7,800 journals in all disciplines. Coverage is from 2005 to present, with over 3 million records[42]
  • Book Citation Index (BCI) covers more than 116,000 editorially selected books. Coverage is from 2005 to present, with over 53.2 million records[43]
  • Conference Proceedings Citation Index (CPCI) covers more than 205,000 conference proceedings. Coverage is from 1990 to present, with over 70.1 million records[44]


As Clarivate acquired ProQuest, various products of ProQuest are being operated under Clarivate, which encompasses products that ProQuest had taken on relatively recently, through acquisitions of its own—notably those of Innovative Interfaces: Vega, Sierra, Polaris, Millennium, and Virtua.[45]

Annual lists and reports[edit]

Highly Cited Researchers[edit]

Clarivate publishes an annual Highly Cited Researchers list. The list compiles "the world's most influential researchers of the past decade, demonstrated by the production of multiple highly-cited papers that rank in the top 1% by citations for field and year in Web of Science."[52] According to Clarivate, researchers are selected for their "exceptional performance" in one or more of 21 fields (those used in Clarivate Essential Science Indicators, or ESI) or across several fields. The 2019 list of Highly Cited Researchers was released on November 19, 2019.[53]

Clarivate Citation Laureates[edit]

Clarivate Citation Laureates, formerly Thomson Reuters Citation Laureates, is a list of candidates considered likely to win the Nobel Prize in their respective field. The candidates are so named based on the citation impact of their published research. Thomson Reuters Citation Laureates was established in 1989. The list pertains to likely Nobel Prize winners in medicine, chemistry, physics, and economics. There appears to be a correlation between high citation rates for a published researcher and the award of prestigious accolades. Furthermore, citation rates disclose researchers furnishing instrumental contributions that advance the science of their respective field. Finally, choosing one tenth of one percent (0.1%) of the highest impact papers winnows the analysis to the topics and people most likely to be selected by Nobel selection committee.[54][55][56]

From 2002 to 2020, 59 individuals listed as Citation Laureates have received Nobel prizes.[57]

Journal Citation Reports[edit]

Journal Citation Reports (JCR) is an annual publication by Clarivate.[58] It has been integrated with the Web of Science and is accessed from the Web of Science Core Collection. It provides information about academic journals in the natural and social sciences, including impact factors. JCR was originally published as a part of the Science Citation Index. Currently, the JCR, as a distinct service, is based on citations compiled from the Science Citation Index Expanded and the Social Sciences Citation Index.[59] As of the 2023 edition, journals from the Arts and Humanities Citation Index and the Emerging Sources Citation Index have also been included.[60]

Top 100 Global Innovators Report[edit]

The annual Top 100 Global Innovators report identifies the world's most innovative organizations. These businesses have successfully developed valuable patented inventions that also have strong commercialization potential based on market reach and impact on other downstream inventions. The 2020 Top 100 Global Innovators Report was released on February 19, 2020.[61]
