Gemstar-TV Guide International Inc. filed a patent-infringement lawsuit Thursday against Tribune Co.'s Zap2It (www.zap2it.com) Web site, which contains TV-programming guides, Reuters reported.

The lawsuit claimed that the technology Zap2It uses to help online readers search for TV listings in their area is under patent by Gemstar's TV Guide Interactive unit, according to Reuters.

In the suit, filed in Delaware, Gemstar-TV Guide said it is seeking damages and an injunction against Zap2It, adding that past efforts to reach an agreement with Tribune have been unsuccessful, Reuters reported.
