Following its win on appeal, AstraZeneca Pharmaceuticals failed to persuade a federal judge to award it attorney fees for its defense against allegations that it violated Teva Pharmaceutical Industries’ patent for a component to drugs that lower cholesterol.

AstraZeneca prevailed in district court as well as on appeal in the Federal Circuit, but did not convince U.S. District Judge William H. Yohn Jr. of the Eastern District of Pennsylvania that the case was “exceptional,” which would have warranted the awarding of fees.
