Silicon Graphics Inc says it has been granted its motion for summary judgement in the patent infringement case bought against it by TM Patents LP, an entity created out of the bankrupt estate of the old Thinking Machines Corp. Filed back in 1997 against Cray Research Inc, the TM suit charged that the Cray T3E and T3D supercomputers and SGI Origin2000 server infringed patents held by Thinking Machines. The dispute over the Origin servers was settled earlier in the litigation, but now the court has ruled that the T3E does not infringe any of the patents. US District Court Judge Sandra Armstrong also ruled that the T3E’s predecessor, the T3D, does not literally infringe any of the patent claims remaining in the case. SGI said that TM Patents sued the company without any basis in fact or law.
