From Slashdot, news comes that the University of Wisconsin Madison has sued Sony, claiming that Sony's PS2 chip violates a 16-year-old patent held by the university.
There isn't much information out there about the suit (does anybody have the documents?), but from this article we learn: "It's thought that the lawsuit centres on the manufacturing process involved in creating Emotion Engine devices, not any technology on board the chip itself, and as such both Sony and Toshiba are targetted by the suit." The university is seeking damages and an injunction on further production of the chip.
A quick search on the Patent Office website reveals all of the university's patents applied for and issued in 1986. I am incapable of understanding patents; perhaps the patent at issue is 4,630,094 ("Use of metallic glasses for fabrication of structures with submicron dimensions") or 4,744,863 ("Sealed cavity semiconductor pressure transducers and method of producing the same")?
