Pure Data Systems, LLC v. Electronic Arts Inc.

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.

Monument Patent Holdings, LLC appears to have rebooted the content delivery campaign that it began this past April. The NPE, through its controlled plaintiff Pure Data Systems, LLC, has notified the Eastern District of Texas of its voluntarily dismissal (without prejudice) of the cases that it filed three months ago against CBS (CBS Interactive, CNET), Time Warner (CNN Interactive), Twenty-First Century Fox (Fox Broadcasting, Fox News, Fox Sports), and Gannett (USA Today). At the same time, Pure Data has filed a new Delaware case against EnterpriseDB (1:17-cv-00876), asserting the same two patents (5,999,947; 6,321,236) previously at issue. The patents generally relate to the distribution of database differences; accused of infringement is the defendant’s system for replicating such differences on client computers as needed. The move to Delaware follows a similar jump in another Monument campaign, filed by controlled subsidiary Digital Stream IP, LLC over satellite and digital radio.

Pure Data Systems, LLC, a subsidiary of Monument Patent Holdings, LLC, has launched a new campaign over two patents (5,999,947; 6,321,236) generally related to the distribution of database differences and previously asserted in litigation. Pure Data’s complaints accuse CBS (CBS Interactive, CNET) (6:17-cv-000210), Time Warner (CNN Interactive) (6:17-cv-000209), Twenty-First Century Fox (Fox Broadcasting, Fox News, Fox Sports) (6:17-cv-000211), and USA Today (6:17-cv-000208) of infringement through the process by which content delivered to their websites and mobile apps is replicated across multiple servers. Xanthus Data Technologies, LLC, an affiliate of Daniel F. Perez, asserted both patents against Citrix and LinkedIn in a short-lived 2015 litigation campaign.
