Court Rejects Sony's Appeal against Patent Ruling

A federal judge rejected an attempt by units of Sony Corporation to overturn a $90.7 million jury verdict in a patent case that could affect a forthcoming generation of Sony videogame machines. At issue is what game makers call haptic technology, which is used to make game controllers vibrate in response to action on a TV screen. Immersion Corp. filed a suit in 2002 alleging that Sony’s PlayStation products infringe Immersion patents on the technology. A jury in Oakland, California, ruled in Immersion’s favor in September 2004.
