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.
Digital Stream IP, LLC, an affiliate of Monument Patent Holdings, LLC, has added two cases to its radio communications campaign, suing CBS (CBS Radio) (2:17-cv-00313) and iHeartMedia (2:17-cv-00315) over one (the ‘913 patent) of the three patents (6,757,913; 7,962,090; 8,265,545) already at issue. The patents generally relate to digital audio receivers; Digital Stream IP’s earlier cases have focused on the sale of satellite radio units, made by, for example, Sirius XM, and sold in automobiles, including the vehicles sold by defendants BMW, Daimler (Mercedes-Benz), GM, Honda, and Nissan. These two newest complaints target digital audio transmitters used with CBS and iHeart radio stations.
