Database Duplication Campaign Expands in Delaware, Adds Case in Washington

  • November 6, 2017

Pure Data Systems, LLC, a subsidiary of Monument Patent Holdings, LLC, has added three more Delaware cases—one each against Imgur (1:17-cv-01585), Mercari (1:17-cv-01586), and Pinterest (1:17-cv-01587)—and a Western District of Washington case—against Valve (2:17-cv-01659)—to the litigation campaign that it began this past April. The complaints each assert two patents generally related to the distribution of database differences, with the defendants accused of infringement through the use of systems designed to conform information accessed by their websites and mobile applications. The new suits join one active case, filed in June, targeting EnterpriseDB’s system for replicating database differences across multiple computers.
