Thomas J. Filarski is a partner in Steptoe's Chicago office, where he is a member of the Intellectual Property and related litigation groups. Mr. Filarski is acknowledged as a leading trial lawyer particularly in patent, Hatch-Waxman, and International Trade Commission matters.
Intellectual Asset Management (IAM) magazine writes that Mr. Filarski is “particularly adept when it comes to Hatch-Waxman Act and ITC litigation” and is a “superb attorney with topnotch licensing expertise.” One client says, “he 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.” Another client refers to Mr. Filarski as “one of those quiet, humble people, but he is very crafty and he instills great confidence.”
He represents prominent companies in the pharmaceutical, semiconductor, medical device, biotech, chemical, electrochemical and mechanical industries.
He is the past president of the Licensing Executives Society (USA and Canada), a professional organization focusing on the development and transfer of technology and intellectual property. He also serves on the advisory board of the Clean Energy Trust, which connects entrepreneurs, researchers, and early stage companies with the expertise and capital needed to become sustainable businesses.
Mr. Filarski speaks and writes regularly to professional and industry groups in the United States and abroad on patent litigation and intellectual property topics. He authors the chapter "Patent Defenses" in BNA Books' Patent Litigation Strategies Handbook, now in its third edition, and he was featured in the Business Edition of Leading Lawyers Network magazine in January 2009. Mr. Filarski’s professional affiliations also include Richard Linn American Inn of Court, Chicago Bar Association, American Bar Association, American Intellectual Property Law Association, and Federal Circuit Bar Association.
