About John

John Dragseth is a senior principal of Fish & Richardson P.C., and has been named one of the top 50 IP attorneys in the country under the age of 45. He has also been named a Minnesota SuperLawyer multiple years.  His practice centers on complex legal analysis and writing – in federal appeals, patent prosecution, reexamination, pre-suit and due diligence investigations, and patent opinions. His prosecution work centers on cloud computing, mobile computing, software, medical devices, and mechanical technologies (including HVAC). John has led the briefing on more than 60 appeals to the U.S. Supreme Court and U.S. Court of Appeals for the Federal Circuit, where he was previously a law clerk to the Honorable Raymond C. Clevenger III. He has extensive experience in taking over cases on appeal and framing them for the Federal Circuit, while working closely with trial counsel. He also enters cases frequently as a “fixer” — helping with tough and important issues. (The similarities with George Clooney’s “Michael Clayton” character end there.) John writes and lectures frequently on a variety of patent law topics. He is also an adjunct professor teaching IP litigation at the University of St. Thomas Law School, and has authored case books on patent law and IP litigation (very exciting reads). He was raised on a small grain and sugar beet farm in Northern Minnesota.
