Parallel Processing Corporation v. Sony Corporation of America
United States District Court, Eastern District of Texas
Case No. 07-353, Filed July 26, 2007

Case Update:

This case was dismissed without prejudice on October 8, 2007. Plaintiff Parallel Processing Corp filed a notice of voluntary dismissal under Rule 41(a) of the FRCP. This allows for the plaintiff to dismiss an action without a court order by filing a notice of dismissal before the opposing party serves either an answer or a motion for summary judgment. In this case Sony had not responded to PPC’s suit with any court filings before PPC filed the voluntary dismissal.

Original Post:

Parallel Processing Corp. has filed a lawsuit alleging that Sony's PlayStation 3 infringes U.S. Pat. No. 5,056,000, entitled "Synchronized parallel processing with shared memory." Not the sexiest of patents with respect to game console hardware, but given the convergence of game consoles and general purpose computers, it's not surprising.

The lawsuit is Parallel Processing Corp v. Sony Corp. of America, case number 07-353, in
the U.S. District Court for the Eastern District of Texas, filed July 26, 2007.
