U.S. Court of Appeals for the Federal Circuit
Evolved Wireless, LLC v. Samsung Electronics America, Inc.
August 31, 2026
Summary
The court affirmed the district court’s rulings on all three appeals. It upheld the denial of a new infringement trial because substantial trial evidence supported the jury’s finding that LTE-compliant products need not use a collision-free dedicated preamble, and it upheld summary judgment because the Qualcomm license survived termination of the parties’ agreement. The court also held that substantial evidence supported the jury’s finding that the asserted claims satisfied the written-description requirement.
