The Kudelski Group's (SIX:KUD.S) OpenTV and Nagravision subsidiaries have filed a patent infringement suit against Shaw Communications (TSX:SJR.B) in the Federal Court of Canada. The lawsuit alleges that Shaw's system infringes six Canadian patents owned by Nagravision and OpenTV.
Kudelski Group's asserted patents relate to a wide variety of features in Shaw’s system, including its pay TV purchasing, distribution, viewership monitoring, and interactive television systems. The lawsuit seeks a preliminary injunction prohibiting deployment of Shaw's recent release of BlueSky TV, which is a licensed version of Comcast's (NASDAQ:CMCSA) X1 platform. Shaw unveiled the service in January.
OpenTV has sued a number of companies over video patents, including Yahoo!, Verizon, Netflix, Apple, and most recently the NFL.
