Sterne Kessler Building Interior

James M. Eaton, Ph.D.



James M. Eaton, Ph.D., is an associate in Sterne Kessler’s Biotechnology & Chemical Practice Group. James assists in worldwide procurement of patents in the biotechnology, chemical, and pharmaceutical industries. His experience also extends to assisting in the preparation of validity, infringement, freedom to operate, and patentability opinions.

James’ technical expertise focuses on biochemistry and molecular biology. While earning his Ph.D., James elucidated molecular mechanisms controlling insulin signaling and fat synthesis in adipocytes. He also has experience in small molecule synthesis. During his graduate studies, he received a Pharmacological Sciences training grant from the National Institutes of Health.

James earned his J.D. from the University of Richmond School of Law. He received a Ph.D. in Pharmacology and M.S. in Biological and Physical Science from the University of Virginia, and a B.A. in Chemistry from Kenyon College.
