IP Alert: Supreme Court Requires Deference to District Court’s Fact-Finding on Claim Construction

January 20, 2015

Today, in Teva Pharmaceuticals USA, Inc. v. Sandoz, Inc., the U.S. Supreme Court issued an important opinion relating to patent claim construction. The Court held that an appellate court must apply a “clear error” standard of review, not a de novo standard of review, when reviewing the “evidentiary underpinnings” of a district court’s claim construction. This case will be significant in many respects in future appeals to the Federal Circuit.  

Fitch Even attorneys are reviewing the decision and will provide a more-detailed analysis in an upcoming alert.
