Sony will continue to sell its PlayStation 2 in the United States while it appeals a court-ordered ban on sales of the market-leading game console, the company said Monday. Judge Claudia Wilken of the U.S. District Court for Northern California issued the order late last week in a patent infringement case filed against Sony Computer Entertainment by Immersion, a San Jose, Calif.-based developer of "haptics" technology.

Immersion claims that Sony's implementation of force feedback in its PlayStation 2 and the original PlayStation consoles infringes on its patents. Microsoft paid the California company $26 million two years ago to settle similar claims regarding its PC joysticks and other products. Sony has fought those charges and suffered a setback late last year, when a jury sided with Immersion and ordered the console maker to pay $82 million in damages. Enforcement of the verdict was delayed, pending the judge's ruling on post-trial motions. Read the rest of the article at News.com.
