I've lost track of the number of people who have tried to sue Sony over the PS3 and/or Blu-Ray. Suffice to say, it's loads. Now, it's loads +1. Parallel Processing Corporation claim that the PS3's fancy Cell chip violates a patent they filed all the way back in 91 for something with "synchronized parallel processing with shared memory". The suit was filed on July 26 in Texas, and whines that the PS3 is "causing irreparable harm and monetary damage". Presumably to PPC. Not Sony...
