While Rovi is holding off on litigation with Dish Network and EchoStar as it negotiates possible licensing extensions, the company has filed a patent infringement lawsuit against cable giant Comcast. In the Comcast suit, “Rovi asserts infringement by Comcast of 14 U.S. patents for features in the cable operator’s products,” reports Variety. “That includes the way that Comcast implements remote DVR recording, AnyRoom DVR and X1 search.” Rovi, which says it has licensing deals with eight of the top 10 U.S. providers, recently reached a deal with Time Warner Cable to extend its interactive program guide and licensing agreement to the end of this year.
