Gregory S. Tamkin

Gregory S. Tamkin is an experienced intellectual property litigator and a co-leader of Dorsey & Whitney LLP's Trial Group, also serving on the firm's Management Committee. His practice spans patent, trademark, and copyright disputes, often handling complex commercial cases in various venues, including international arbitrations, jury trials, and appellate matters. While the tracked case shows him as lead counsel for a defendant (Haemonetics Corporation v. Terumo BCT, Inc.), his broader representative experience includes work for both plaintiffs and defendants. Technology areas he has handled include medical devices/blood processing, photovoltaic technology, LED-based products, and issues relating to patent-eligible subject matter, specifically software patents. Dorsey & Whitney's IP practice is also noted for its strength in biotechnology issues.

Mr. Tamkin has achieved significant outcomes in his career. Notably, he secured summary judgment in a patent infringement case, Sterisil v. ProEdge Dental Products, which was then resolved during appeal. He also represented Solannex, Inc. as plaintiff's counsel in a patent dispute concerning photovoltaic technology, leading to a confidential settlement after claim construction. Furthermore, he successfully overturned an unfavorable district court ruling on appeal at the Federal Circuit in a preliminary judgment motion against an infringer of LED-based products in Fiber Optic Designs, Inc. and Holiday Creations, Inc. v. Seasonal Specialties, LLC. While his professional profile and the firm's IP practice emphasize comprehensive intellectual property services, specific mentions of IPR or PTAB experience are not explicitly detailed in the publicly available information.

Mr. Tamkin is admitted to practice in California and Colorado, as well as before the U.S. Court of Appeals for the Ninth, Tenth, and Federal Circuits, and numerous U.S. District Courts. He earned his J.D. from the University of Virginia School of Law in 1994 and his A.B., cum laude, from Dartmouth College in 1991.
