Case: Patents/Procedure (Fed. Cir.)

The Federal Circuit vacated and remanded the decision of a federal district court in Wisconsin granting Cherry Optical Inc. summary judgment on Inland Diamond Products Co.'s action for patent infringement. The appeals court determined that the district court erred by giving issue-preclusive effect to facts found under the preponderance standard when adjudicating the validity of the claims under the clear and convincing standard.
