Rolls-Royce files patent infringement complaint

Rolls-Royce today filed an amended complaint alleging infringement by United Technologies Corporation (UTC) of the Rolls-Royce swept fan blade patent in the Federal Court for the Eastern District of Virginia in the United States. The complaint specifically alleges that the fan stages on the Engine Alliance GP7200 engine and on UTC's PW1000G engine (also known as the Geared Turbofan) infringe the Rolls-Royce patent. The complaint also alleges that a number of other UTC aero civil engines infringe the Rolls-Royce patent. Rolls-Royce is seeking damages and injunctions.

It is expected that the case will be heard before a jury in the Eastern District of Virginia in the first half of 2011.

The origins of this case date back to the late 1990s. The dispute was initiated by UTC when it applied to the US Patent Office to have the Rolls-Royce swept fan blade patent struck out. UTC's efforts were unsuccessful and the validity of the Rolls-Royce patent has been upheld in the United States.
