Eurocopter v. Bell Helicopter Textron Canada Limitée

Eurocopter v. Bell Helicopter Textron Canada Limitée

Claim 15 of Canadian Patent No. 2,207,787 is valid and was infringed by Bell's Legacy landing gear; Claims 1-14 and 16 are invalid for lack of demonstrated utility/sound prediction and overbreadth (claim 16 covering embodiments offset rearwards lacked demonstrated utility at filing); the Production gear does not infringe because it lacks essential claim elements (notably double curvature/integrated front cross piece); injunction, destruction of Legacy gears (subject to limited retention for foreign litigation), entitlement to damages including punitive damages (quantum deferred), interest and costs reserved.
