Mark Nagumo is a chemical patent attorney in the firm’s Chemical Patent Practice group. His practice focuses on chemical patent issues, and he consults and offers opinions on a full range of patent issues.
Prior to joining the firm, Mr. Nagumo spent 29 years at the United States Patent and Trademark Office (USPTO), including 17 years as an Administrative Patent Judge (APJ) at the Patent Trial and Appeal Board (PTAB) (formerly the Board of Patent Appeals and Interferences (BPAI)), three years as an Associate Solicitor, and seven years as an Examiner (three years as a Primary Examiner). As an Administrative Patent Judge and as an Associate Solicitor, he handled appeals to the patent Board, and to the Court of Appeals for the Federal Circuit, respectively, throughout the chemical technologies, as well as cases in mechanical and electrical areas. As an Examiner, Mr. Nagumo focused on high polymers, metallocene and metathesis polymerization catalysts, and polymers having unusual properties and applications, including nonlinear optical properties, and liquid crystal polymers. Before joining the Patent Office, Mr. Nagumo was a research chemist at the Naval Research Laboratory (Washington, D.C.) for about seven years, starting in the Optical Sciences Division and ending in the Bio/Molecular Engineering Branch of the Chemical Division.
Mr. Nagumo’s practical experience in chemical research, especially using optical spectroscopies to study biomolecules and other materials, as well as a wide range of other analytical techniques, provide him with a solid basis for analyzing issues of patentability throughout chemical and materials technologies.
