A large litigation campaign initiated by Realtime Data LLC (RTD) nearly eight years ago continues to grow. Last week, the NPE filed four new cases asserting a group of data compression patents against CenturyLink (with Veritas, 6:16-cv-00087), Dell (with EMC, Iland Internet Solutions, and Veeam Software, 6:16-cv-00089), HP (with Hewlett-Packard Enterprise and Silver Peak Systems, 6:16-cv-00086), and Oracle (6:16-cv-00088). The companies’ compression products and services, including Dell’s Rapid Recovery software, HP’s StoreOnce, and Oracle’s SecureFiles, are the accused products. Each suit involves two to five patents; seven of the patents-in-suit (6,597,812; 7,161,506; 7,358,867; 7,395,345; 7,415,530; 8,643,513; 9,116,908) have been previously asserted in this campaign, but one (9,054,728) had not been litigated prior to last week. The ‘728 patent, which issued in June 2015, is asserted in all four of the new cases. These latest filings bring the total number of defendants in RTD’s campaign to 57, and the number of patents-in-campaign to 23.
