The U.S. Court of Appeals for the Federal Circuit Wednesday gave a lower court and the U.S. Patent and Trademark Office (USPTO) a lesson in the plain meaning of the law when it comes to patent term adjustments (PTAs). In a precedent-setting decision, the Federal Circuit reversed the district court's grant of summary judgment to the USPTO and sent Supernus Pharmaceuticals Inc. v. Iancu back to the court for a do-over.
