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.

Cox filed the suit  (posted by the Atlanta Business Chronicle) on May 11 in the U.S. District Court for the Northern District of Georgia, alleging that AT&T is infringing on the following 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.
