Case: Patents/Specification (Fed. Cir.)

The Federal Circuit reversed the decision of the District of Colorado holding that Sandoz Inc. failed to prove a challenged claim of Duke University and Allergan Sales LLC’s patent that relates generally to treating hair loss using compositions containing prostaglandin F analogs invalid for lack of adequate written description. According to the appeals court, no reasonable fact-finder could have found anything other than clear and convincing evidence that the challenged claim is invalid for lack of adequate written description.
