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.
