Jon R. Trembath

With more than 20 years of intellectual property litigation experience, including several trials and appeals, Jon has dealt with complex legal issues and difficult logistics such as managing a suit involving 37 patents in the semiconductor and telecommunications arts. Jon has also represented smaller clients who depend on their intellectual property for survival.

Jon is a trial lawyer and litigator in the Denver office who has focused primarily on patent litigation. He enjoys working on intellectually challenging cases since his clerkship at the U.S. Court of Appeals for the Federal Circuit and devising winning strategies that give his clients competitive advantages in the marketplace. His strong analytic and communication skills allow him to explain complex technologies using simple, understandable language and to tell a compelling story while preparing his cases for appellate success.

Jon has a clear record of success at both the trial stage of litigation and with appeals before the U.S. Court of Appeals for the Federal Circuit, winning all of the Federal Circuit appeals he controlled. Recently, Jon prevailed in an appeal that reversed a trial-court judgment with a $50 million dollar exposure to his client, a construction products manufacturer. He has represented clients such as Motorola, Freescale, Robert Bosch Tool Corp., Microsoft, Siemens, 3M, Honeywell, Harman Kardon, Terex, OfficeMax, Vermeer Manufacturing Co., U.S. Ecology, Trophy Ridge, Grouser, Department 56, Adaptec, KV33, Featherlite, Smash, Bay West Paper Co., Digital River, Halo Innovations, Cold Spring Granite, Pari, Carbo Ceramics, Connect-A-Dock, Intercept Corp., Onset Pipe, Powerscreen and Loegering Manufacturing.

While the focus of Jon’s practice is on patent litigation, he has successfully obtained ex parte seizure orders, even with unregistered trademarks, and has litigated color and other trademarks and right of publicity claims. Jon has significant experience with the new Inter Partes Review process at the U.S.P.T.O. As a founding board member and current president of the Colorado IP Inn of Court, Jon works to improve collegiality and foster professionalism in the Bar. He is a frequent speaker and writer on intellectual property law issues.

At the office, Jon can often be found at the standing desk that he built. When not working, his spare time is spent with his wife and ten children. He also likes to sneak away on motorcycle rides, to fish, hunt, and to visit his dad on the farm.
