Sony is Being Sued for the Processor Used in PS3

Sony has already been slapped with patent suits over the construction of its PlayStation 3 Blu-ray discs and the system's digital security technology. Now the electronics giant is being taken to court over the parallel processing Cell chip that powers its latest console.

In its suit, Parallel Processing Corporation of Newport Beach, California, cites a patent for "synchronized parallel processing with shared memory" that was approved on October 8, 1991. The patent was originally assigned to International Parallel Machines of New Bedford, Massachusetts, while Parallel Processing Corporation describes itself as its "exclusive licensee."
