PARKERVISION, INC. v. VIDAL

Court: US Court of Appeals for the Federal Circuit

Docket: 22-1548

Opinion Date: December 15, 2023

Areas of Law: Government & Administrative Law, Intellectual Property, Patents

The case involves ParkerVision, Inc. appealing a decision by the Patent Trial and Appeal Board (Board) that invalidated one of its patents, U.S. Patent No. 7,110,444 ('444 patent), owned by ParkerVision, Inc., which relates to wireless local area networks (WLANs) that use frequency translation technology. The Board determined that claim 3 of the patent is unpatentable as obvious in light of prior art. The United States Court of Appeals for the Federal Circuit affirmed the Board's decision. The court found that the Board correctly construed the term “storage element” and did not procedurally err in how it treated certain arguments raised by the parties. The court also found substantial evidence supporting the Board's finding that the patent claim was obvious in light of prior art. The court found no violation of ParkerVision's procedural rights under the Administrative Procedure Act (APA) and no abuse of the Board's discretion in excluding parts of ParkerVision’s sur-reply.
