Jonathan Tuminaro, Ph.D.

Jonathan Tuminaro, Ph.D., is a director in the Sterne Kessler’s Trial & Appellate and Electronics Practice Groups. He has a unique combination of legal and technical expertise—with a Ph.D. in physics and over ten years of experience handling patent matters. He regularly litigates cases at the International Trade Commission, the U.S. district courts, and the Patent Trials and Appeals Board.

Jonathan’s approach to patent litigation follows Albert Einstein’s words: “If you can’t explain it simply, you don’t understand it well enough.” In each engagement, Jonathan works to understand even the smallest of details to craft compelling stories that inform and persuade both judges and juries. He has applied this approach to a wide range of complex technologies including wireless communications, hand-held devices, computer architecture and software, medical devices, and pharmaceuticals.

Jonathan received his Bachelor’s degree in physics and mathematics from Canisius College, and was a member of the ’95-’96 Men’s Basketball team that won the Metro Atlantic Athletic Conference Tournament and earned an automatic bid to the NCAA Division I Men’s Basketball Tournament. He then went on to earn a Master’s degree and a Ph.D. in physics from the University of Maryland, and he received his J.D. from George Mason University School of Law.

Jonathan has been named a 2015, 2016, and 2017 DC Super Lawyers “Rising Star” in IP litigation.

Jonathan is also is a contributing author of Patent Office Litigation, Second Edition, published in 2017, the book provides a fresh and comprehensive exploration of patent office litigation proceedings, including how the proceedings interact with other aspects of patent procurement and enforcement, while delivering practical analysis and advice. This second edition of Patent Office Litigation is the follow up to the first version of the book that was published in 2012 by Thomson Reuters Westlaw that focused on the contested proceedings that were introduced under the America Invents Act that year
