Teddy S. Gron is a chemical biotechnical patent attorney in the firm’s Chemical Patent Prosecution group. His practice focuses on chemical and biotechnological patent issues at the appellate and prosecution levels, and he consults and offers opinions on a full range of patent issues.

Prior to joining the firm, Mr. Gron spent 35 years at the United States Patent and Trademark Office (USPTO). He served 14 years as an Administrative Patent Judge (APJ) on the Board of Patent Appeals and Interferences (BPAI), six years as an Associate Solicitor, and 10 years as a Primary Examiner.

Mr. Gron has appeared in, and argued, more than 50 cases before the U.S. Court of Appeals for the Federal Circuit, presided over an array of ex parte and inter partes proceedings before the Board, and authored a host of Appellee’s Briefs for the USPTO and decisions for the Board in interference and contested cases. He appeared for the Commissioner of Patents and Trademarks in such landmark Federal Circuit cases as: In re Deuel (1995); In re Goodman (1993); In re Wright (1993); In re Bell (1993); In re Clay (1992); In re Baxter Travenol Labs (1991); In re Vaeck (1991); and In re Gorman (1991).

With his vast USPTO experience, Mr. Gron has an extraordinary sense of what is and is not patentable and how to craft claims that will broadly protect his clients’ innovations. Drawing upon his experience at the USPTO, especially his time as an Administrative Patent Judge, Mr. Gron is able to skillfully address and resolve his clients' patentability challenges.

Mr. Gron began his career in research and development in the fields of polymeric coatings and adhesives. This practical experience provided him with a solid understanding of chemical technologies. Mr. Gron lectures widely on appellate practice and patent prosecution in the United States and abroad and has been asked to testify as an expert witness on appellate practice.
