TiVo Accuses Sonicblue of Stealing Technology

TiVo Inc. filed a lawsuit accusing interactive-television rival Sonicblue Inc. of stealing technology that lets viewers store some programs while they watch another show.

TiVo filed the federal patent-infringement lawsuit on Jan. 23 against Sonicblue and its ReplayTV Inc. unit.

Sonicblue and TiVo are battling for supremacy in the growing market for video-data recorders. In December, Sonicblue accused TiVo of infringing a Sonicblue patent for devices that pause and replay TV shows.

TiVo’s lawsuit seeks damages and a court order blocking Sonicblue and ReplayTV from selling any infringing products.

Shares of Alviso, Calif.-based TiVo fell 11 cents to $5.75, while Santa Clara, Calif.-based Sonicblue fell 15 cents to $4.60, both on Nasdaq.
