Los Angeles - Gemstar-TV Guide International (NASD: GMST), a provider of electronic program guides for digital TV services, announced on Thursday that it has filed a patent infringement lawsuit against cable TV provider Virgin Media in the U.K.

Los Angeles-based Gemstar alleges that Virgin Media is infringing on three of its European patents, including claims directed to techniques for providing certain interactive program guides (IPGs), and for handling recordings from IPGs.

"We have worked diligently to license Virgin Media for their distribution of various set-top boxes that contain IPGs covered by our patents, but negotiations did not lead to a resolution," said Samir Armaly, executive vice president of intellectual property and licensing at Gemstar-TV Guide.
