AP Racing Ltd v Alcon Components Ltd

A caliper infringes claim 1 of UK Patent No. 2,451,690 only if it has a peripheral stiffening band that is appreciably beyond and distinct from limb material at the ends of cylinders, materially increases stiffness, and is asymmetric about any lateral axis in plan view. Only Alcon's caliper CAR 9549Y73 meets these criteria; the others do not.
