Rolls-Royce Sues UTC for Patent Infringement
Rolls-Royce today filed a complaint alleging infringement by United Technologies Corp.

Rolls-Royce today filed a complaint alleging infringement by United Technologies Corp. (UTC) of the Rolls-Royce swept fan blade patent. The complaint specifically identifies the fan stages on both the Engine Alliance GP7200 engine and the Pratt & Whitney PW1000G engine. It also alleges that a number of other UTC aerospace civil engines infringe the Rolls-Royce patent. In a statement released today, Rolls-Royce said it seeks unspecified damages and injunctions.

UK-based Rolls-Royce expects a jury to hear the case in the first half of next year in the Federal Court for the Eastern District of Virginia.
