Appellate Litigation

At the Patent Trial and Appeal Board, the final written decision is often only the beginning. That’s why McNish PLLC also represents clients on appeal. An experienced advocate at the U.S. Court of Appeals for the Federal Circuit, Kevin McNish has worked on appeals arising from more than a dozen inter partes reviews. In those appeals, he has litigated issues of patent law, administrative law, and constitutional law, both by writing briefs and arguing at oral hearings.

Although McNish PLLC’s appellate practice principally focuses on Federal Circuit appeals of PTAB proceedings, Kevin also represents clients in appeals and mandamus proceedings arising from patent infringement litigation in the U.S. District Courts. He has also prepared and contributed to briefs for amici curiae at both the Federal Circuit and the Supreme Court of the United States.
