Sony loses force feedback patent infringement suit

A US District Court judge has ordered Sony to pay over $90 million in damages and interest to settle a patent infringement case with Immersion, a developer of force feedback technology. The Dualshock controllers that Sony ships with its PlayStation and PlayStation 2 consoles apparently infringe on Immersion's patents, and Sony has also been ordered to pay licensing fees for hardware already sold in the US. The Judge even went so far as to issue an injunction barring Sony from selling infringing PlayStation hardware in the US, but that injunction has been stayed while Sony files an appeal. Interesting, Microsoft settled a similar suit with Immersion for only $26 million nearly two years ago.
