ATI sued by SGI

The patent, 6,650,327, describes a display system with floating point rasterisation and buffering.

SGI wants a district court to injunct ATI, and naturally it wants damages as well.

Dennis McKenna, CEO of SGI, said he and his firm will aggressively protect and enforce its intellectual property to the hilt.

ATI has a complex cross licensing deal with Intel which no outsider has ever really fathomed, and of course ATI is being acquired by AMD, which has a complex cross licensing deal with Intel. It's all rather tangled. µ
