Finnegan was one of the top firms at the U.S. Court of Appeals for the Federal Circuit in 2018 according to a Law360 review of patent opinions issued by the specialty appeals court.
Finnegan argued more than 20 cases before the Federal Circuit last year, 12 of which resulted in wins, including a victory for Sprint that upheld a $140 million jury verdict in the telecom’s favor and a ruling in favor of PPC Broadband Inc. preserving a $61 million win in a patent infringement case over coaxial cable connectors. “We’ve got a pretty diverse practice, and where the Federal Circuit cases are originating, we’re active in all those forums as well. I think that’s a big part of it,” said Erik Puknys, partner at Finnegan and head of the firm’s appellate section.
Puknys noted that Finnegan’s deep bench of appellate specialists (including more than 40 attorneys who clerked at the Federal Circuit) is another reason for the success. “If you limit it to just a few superstars that are going to argue, you’re going to limit your exposure at that appellate court. We have so many attorneys who are comfortable there.”
