Trade Immersion Corporation
in 2002, Sony and Microsoft were sued by Immersion for violating patents for the use of vibration functions in their gaming consoles. Specifically, they were charged with infringing claims in the U.S. patent 6,424,333 and the U.S. patent 6,275,213 (2000 and 2001 were filed as additions to 6,088,017 U.S. patents, itself 1998, all "reaction by tracking device interface device"). Both patents were continuing patent applications originally filed in November 1995. Nintendo was not involved in the case, as the technology used in the Pak and GameCube rumble controller (and, later, Wii Remote) is based on a different design, which holds Nintendo's American patent 6200253 and the American patent 6676520 based on a Japanese patent application filed on October 9, 1995. While Microsoft settled out of court, buying a 10% stake in immersion, Sony continued to defend the case. The lead attorney for Gommar in this case was Morgan Chu, the defense's focus on the patent for the feedback controller that Sony licensed from Logitech during 1998. Sony, with a jury awarding immersion $82 million for seven years that dualShock controller was on the market, which with the addition of a judge of interest and costs before the verdict, totaled $90.7 million. In addition, the ruling asked Sony to suspend the sale of all controllers containing patented immersion technology, including all Console Packages PlayStation and PlayStation 2. Sony appealed this decision It was able to sell its products during the appeal. On March 8, 2006, Sony lost the u.S. District Court appeal and subsequently appealed to the U.S. Court of Appeals for the Federal Circuit. Once again, the order to stop the sales of the offending observers was suspended pending the outcome of the appeal.
