Sony has been hit with yet another patent infringement lawsuit. This one targets the Cell processor, the brains of the PlayStation 3.

A company that claims to be located in Newport Beach, CA, Parallel Processing Corporation, filed suit in the US District Court for the Eastern District of Texas alleging that the Cell infringes on a patent for "synchronized parallel processing with shared memory."

The patent in question, number 5,056,000, was filed in November 1989 and issued in late 1991—back in the days when the Intel 486 and the Motorola 68040 were the bleeding edge of personal computing while the NES and the Sega Genesis represented the pinnacle of console gaming. It was originally filed by International Parallel Machines, which later assigned the patent to Parallel Processing Corporation.
