Gemstar Sues Tribune Over Online TV Listings
Gemstar-TV Guide International Inc. said it had filed a patent infringement lawsuit against Tribune Co.’s Zap2It, a website that includes TV programming guides.
The lawsuit, filed in Delaware, charges that the technology Zap2It uses to help online readers search for TV listings in their area is under patent by Gemstar’s TV Guide.
TV Guide is seeking damages and an injunction against Zap2It. It said that past efforts to reach an agreement with Tribune over the patent have been unsuccessful.
Tribune, publisher of the Los Angeles Times, declined to comment on the lawsuit.
Separately, Verizon Communications Inc. signed a deal to carry Gemstar’s channel guide on its new television network.
