A federal appeals court refused to revive Teva Pharmaceutical Industries Ltd's patent infringement suit against AstraZeneca Pharmaceuticals LP for the rights to the cholesterol-fighting drug Crestor. The ruling invalidated Teva's patent for Crestor on grounds that AstraZenec invented it first.

Jamie B. Bischoff and Marc J. Weinstein of Ballard Spahr represented AstraZeneca in the case.
