Realtime, Both Data and Adaptive, Keep On Filing New Cases, Most Recently Against Charter, Comcast, Cox, and Facebook

June 8, 2018

Both Realtime Data LLC (RTD) and its subsidiary Realtime Adaptive Streaming LLC (RAS) recently added cases to their respective wings of what has become one of the longest-running, widest-ranging active litigation campaigns. RTD asserted three familiar data compression patents against Facebook (1:18-cv-01373), targeting its Zstandard compression algorithm, as well as products and services “that incorporate the algorithm”. Meanwhile, RAS tagged Charter Communications (1:18-cv-01345), Comcast (1:18-cv-01446), and Cox Communications (8:18-cv-00942), asserting three equally familiar video compression patents against the companies’ respective broadcasting services, training infringement allegations—as it has in most of its cases in this campaign—on the use of the H.264 video compression to standard “to deliver HD video broadcasting products/services” to customers.
