Cox Communications has filed a lawsuit against AT&T claiming that the telco’s IP-fed U-verse TV service is infringing on three Cox patents.
-U.S. No. 7,992,172 (Method and System for Multicast Using Multiple Transport Streams) – Cox claims U-verse TV infringes by encoding interactive program guide pages from the system headend to the subscriber’s receiver/set-top via transport streams.
-U.S. No. 8,332,889 (Generating a personalized video mosaic in a cable services network) – Cox alleges that U-verse’s “My Multiview” app, which provides subscriber-personalized mosaic video channels, infringes.
-U.S. No. 5,999,970 (Access system and method for providing interactive access to an information source through a television distribution system).
Updated: AT&T, whose U-verse TV platform is powered by Ericsson Mediaroom (an IPTV system acquired from Microsoft in September 2013), said it is reviewing the complaint and had no further comment. AT&T lobbed a lawsuit at Cox in August 2014 claiming that Cox is infringing several patents tied to the MSO’s IP voice service, use of set-top boxes and DVRs, and its DOCSIS 3.0-powered high-speed Internet platform.
Cox’s lawsuit is seeking unspecified monetary damages and other relief.
