Today in Oakland, California, Sony lost a patent infringement court battle with Immersion Corp pertaining to Sony's use of Dual Shock and Dual Shock 2 controllers in its PlayStation and PlayStation 2 consoles. Sony has been ordered to pay Immersion $90.7 million in damages and is also expected to stop selling the patent infringing PlayStation and PlayStation 2 systems, as well as over forty games that infringe on Immersion's patent.

The case revolves around US patents 6,275,213 and 6,424,333 which cover "haptic feedback," which entails the use of computer-controlled vibrating motors to provide tactile feedback to the user of a program.

Following the ruling, Sony was granted a temporary stay of injunction while the case pends appeal that will subsequently allow Sony to sell the offending consoles and games until the appeal is resolved. A full listing of the titles affected, with RPGs bolded, is as follows:

A Bug's Life Amplitude Ape Escape Atlantis: The Lost Empire Bloody Roar 2 Cool Boarders 3 Cool Boarders 4 Cool Boarders 2001 Crash Bash Crash Team Racing Drakan: The Ancients' Gate Emperor's New Groove

In early 2002, Immersion filed suit against both Sony and Microsoft for patent infringement, that resulted in Microsoft settling out of court in mid-2003 for the sum of $26 million to license the technology and buying a portion of Immersion in the process.
