Gemstar Claims Patent Infringement

Gemstar International Group Ltd., maker of VCR Plus software, said it’s suing TiVo Inc. for allegedly selling a video recorder with an interactive television listing without Gemstar’s permission. Pasadena-based Gemstar, whose software lets viewers record TV shows by entering a number found in program listings, is seeking an injunction against TiVo and unspecified monetary damages. Gemstar’s Fremont, Calif.-based StarSight Telecast unit filed the patent infringement complaint in federal court in San Jose. Officials at Sunnyvale, Calif.-based TiVo didn’t immediately return a phone call seeking comment. Gemstar shares fell $1.75 to close at $82.63, and TiVo fell $4.88 to close at $50, both on Nasdaq.
