Wexis

Wexis is a humorous portmanteau used to refer to the alleged duopoly of publishing conglomerates that dominate the U.S. legal information services industry – namely, West Publishing and LexisNexis.

Neither of these companies is independent – they are parts of much larger conglomerates that dominate the entire information services sector. West is owned by Thomson Reuters, while LexisNexis is a division of Reed Elsevier.

These companies dispute the allegation that they are a duopoly; LexisNexis actually sued one company which used the terms "Wexis" and "duopoly" in its marketing literature.

The United States district court imposed various requirements regarding the companies' operations in a consent decree resulting from an antitrust inquiry by the United States Department of Justice under the Hart-Scott-Rodino Antitrust Improvements Act in connection with Thomson's purchase of West Publishing, and West's and Lexis's settlement of various outstanding claims in that proceeding. For example, West was required to license the "star pagination" in its printed reporters under certain terms. Otherwise, lawyers in jurisdictions that require citations to all official and unofficial reporters would have to subscribe to both online services to get all the necessary page numbers for citations in their briefs. The judge also had concerns about the Thomson and West products ordered to be divested through a sale to Lexis, primarily statutory and case law publications of Lawyers Cooperative Publishing, such as United States Supreme Court Reports, Lawyers Edition and United States Code Service, but those sales were ultimately approved.
