HP Files Appeal in Patent Dispute

Technology company HP of Palo Alto, Calif., has filed an appeal in its patent dispute with Cornell University and the Cornell Research Foundation. On March 30, 2009, the US District Court issued several post-trial decisions reducing the amount of an earlier jury verdict returned in favor of Cornell from $184 million to approximately $53 million. The patent dispute between HP and Cornell relates to allegations that HP’s PA-8000 family of microprocessors, and servers and workstations incorporating those processors, infringed a patent that describes a way of executing microprocessor instructions. The patent in the litigation expired on Feb. 21, 2006, and therefore the litigation will not affect future sales of HP products.
