Developing appeal strategies based on PTAB and Federal Circuit insights
Decisions by the Patent Trial and Appeal Board (PTAB) of the U.S. Patent and Trademark Office (USPTO) are appealed directly to the U.S. Court of Appeals for the Federal Circuit, where Finnegan attorneys have briefed and argued hundreds of cases, possibly more than any other law firm. We know firsthand the procedural intricacies of both the PTAB and the Federal Circuit. And we understand how to leverage the nuanced differences between these forums on appeal. With only one or two briefs and 15 minutes of oral argument to make your case at the Federal Circuit, Finnegan brings the type of experience that can make all the difference.
As the body of case law develops around PTAB trials, we are constantly monitoring decisions at the Federal Circuit as well as the PTAB, and we use those insights for developing case strategies. Our attorneys are particularly well-suited to analyze the likelihood of success for each possible issue on appeal, counsel clients on which issues to raise, and provide the best overall appeal strategy to succeed and meet our client’s business needs.
Finnegan represented Bausch & Lomb’s licensee Eye Therapies, LLC in an appeal at the U.S. Court of Appeals for the Federal Circuit from a Patent Trial and Appeal Board (PTAB) decision finding Eye Therapies’ patent directed to a low-dose brimonidine treatment for eye redness (Lumify®) to be unpatentable. In a precedential decision, the Federal Circuit agreed with Finnegan’s arguments and found that the Board had wrongly invalidated the patent based on an incorrect claim construction, vacating and remanding the case back to the PTAB. The proceeding settled shortly thereafter
