Douglas B. Wentzel

Doug Wentzel focuses his practice on patent and trade secret litigation. Doug successfully represents clients in district courts across the country and before the International Trade Commission (ITC), Patent Trial and Appeal Board (PTAB), and Patent Office. Doug is adept at understanding complex technologies and has assisted clients in cases covering a broad spectrum of technologies, including wearable health devices, minimally invasive heart repair devices, respiratory therapy products, automotive shock absorbers, microdermabrasion systems, and more. Doug also has experience litigating design patents.

Among other client successes, Doug played an integral role in a high-profile ITC investigation resulting in an import ban of the Apple Watch, and in persuading both the PTAB and the Patent Office not to institute challenges to the patents underlying the import ban.

Doug is actively involved in the legal community and is a co-chair of the Young Lawyers Division of the Federal Bar Association’s Orange County Chapter.
