A partner in the Litigation Department, Chair of the Patent Litigation Group and co-chair of the Recruiting Committee, Catherine Nyarady specializes in patent litigation and is registered to practice in the United States Patent and Trademark Office. She has represented major corporate clients in patent litigations involving a wide range of technologies.

Catherine represented Edwards Lifesciences, the industry leader in artificial heart valves, in multiple litigations and related proceedings, including litigations against Medtronic, Inc. regarding transcatheter heart valves (THV). In 2014, Edwards secured an injunction order against the U.S. launch of Medtronic’s THV products, leading to a settlement in which Medtronic paid to Edwards over $1 billion. This was preceded by two major trial victories: a 2010 jury award of $74 million to Edwards (affirmed on appeal before the U.S. Court of Appeals for the Federal Circuit, certiorari denied) and a 2014 jury award to Edwards of over $393 million.

Catherine is regularly recognized for her work in patent litigation by leading publications such as Chambers USA where sources say she is “technically proficient and has a deep knowledge of patent law” and The Legal 500 where she has been described as having “the big advantage of being a top class litigator combined with a very extensive scientific understanding” and being “very good with tough issues and witnesses.” Catherine has been recognized as a “Client Service All-Star” by BTI Consulting Group and most recently by IAM Patent 1000 as one of The World’s Leading Patent Professionals in 2020.
