United States Federal Circuit
Rolls-Royce, PLC v. United Tech., Corp., 09-1307
In a patent interference proceeding, relating to swept fan blades used on turbofan jet engines, district court's reversal of the Board's judgment against Rolls-Royce is affirmed as the claims of Rolls-Royce's '077 patent are patentable over defendant's '931 application because the '931 application does not render the '077 patent obvious.
