Jeffrey A. Wolfson

Partner | Chair - Patent Prosecution Practice Group

Jeffrey Wolfson, chair of the Patent Prosecution Practice Group, helps clients ranging from Fortune 500 enterprises to start-ups manage their intellectual property and related legal risk. With more than 25 years of experience in patent and intellectual property law, Jeff counsels clients on a range of strategic issues, including:

  • Obtaining and managing portfolios of U.S. and foreign patent and other IP rights, including patent prosecution
  • Negotiating and drafting IP-related commercial agreements
  • Handling key product and service launches and related design-around opportunities and commercial IP strategies

As a reliable advisor to his clients, Jeff has represented enterprises across various industries on technologies such as brand and generic pharmaceuticals, drug delivery devices and materials, petroleum automation technology, behavioral and predictive communication routing and analytics, industrial equipment and processes, automotive polymers, food products and processing, leisure and sporting goods, and more.

Jeff is a trusted business advisor to companies facing competitive headwinds. He has in-depth experience representing clients outside the courtroom to minimize the risk of IP litigation, and to tip the strategic strengths when it cannot be avoided. Jeff prefers to keep clients out of court by obtaining quality patents while considering the latest Federal Circuit and Supreme Court decisions; negotiating and drafting licenses, distribution and other agreements while considering critical client business goals that minimize or even avoid future misunderstandings; and counseling clients on critical IP issues when developing new products and services to reduce risk at the outset.

A registered patent lawyer with a chemical engineering education, Jeff represents clients at the U.S. Patent and Trademark Office; has obtained numerous U.S. and foreign patents; has prepared hundreds of invalidity, non-infringement, patentability, freedom-to-operate, and other product clearance opinions; and has conducted numerous IP diligence evaluations in connection with mergers, acquisitions, and secured financial transactions. Jeff is frequently asked to speak to IP organizations and trade associations on a variety of topics, including IP issues in mergers and acquisitions, patent prosecution and the effects of the America Invents Act, inter partes review proceedings, and the U.S. Biosimilars regulatory framework.

Clients and colleagues have generously rewarded Jeff with accolades, including recognition in DC Super Lawyers, 2013-2023 (Thomson Reuters) for intellectual property. Jeff is AV® Peer Review Rated Preeminent by Martindale-Hubbell® Law Directory. He was also honored in Intellectual Asset Management (IAM) Patent 1000: The World’s Leading Patent Practitioners (Law Business Research), most recently in 2017-2024 for patent prosecution and in certain years also for IP transactions.

In his limited spare time, Jeff volunteers regularly for Brown University, for which he has served as a college class officer for the last 10 years, and on the Board of Directors of the Normandy Hills Homeowner's Association, and enjoys spending time with his former teenagers.
