Thomas J. Filarski represents prominent pharmaceutical, medical device, and electronics companies in patent enforcement and defense actions. According to clients, Tom “has a gift for explaining technology and technological terms in a way that makes them understandable to a judge, a jury, or any decision maker.”
Tom is “on the cutting-edge at all times” in Hatch-Waxman pharmaceutical disputes and “knows how to extract value out of patent rights, and understands the changing nature of the marketplace,” according to IAM Patent 1000.
Recently, Tom successfully led a major drug manufacturer in multiple patent disputes, ultimately allowing the company to sell its several FDA-approved products used to enhance eyelash growth and treat upper respiratory infections and other conditions.
Tom has been involved in landmark patent cases on claim construction and patent venue. He led the teams that resolved the debate within the Federal Circuit over the interpretation of product-by-process claims and, more recently, the Federal Circuit’s decision on “regular and established place of business.”
Tom is the past president of the Licensing Executives Society (USA and Canada), which promotes the development and transfer of technology into commerce. He also served on the board of the Richard Linn American Inn of Court. Tom speaks to professional and industry groups in the United States and abroad on patent litigation and intellectual property topics.
Tom authored and annually updates the chapter on “Patent Defenses” in BNA Books’ Patent Litigation Strategies Handbook and wrote the chapter on “Basics of Patent Law: Strategies for Entrepreneurs and Start-Up Enterprises” in the recent publication Medical Innovation, Concept to Commercialization.
