Gary Levin focuses in patent litigation and counseling and has been involved in dozens of complex patent cases in courts around the country. He has extensive experience in patent cases in the federal courts and in contested proceedings at the Patent Office in all aspects of pre-trial, trial and appellate work, as well as in alternative dispute resolution. His cases have covered such technologies as chemical processing, pharmaceutical and agricultural products, complex medical devices, diagnostic systems, computer database configuration and wireless telecommunication technology. A significant case Gary participated in was Eli Lilly & Co. v. Medtronic, 872 F.2d 402 (Fed. Cir. 1989), in which the Federal Circuit, in a case later affirmed by the Supreme Court, established a defense to infringement for the testing of medical devices to obtain FDA approval. In a Federal Circuit appeal in 2016, Gary obtained a rare reversal, without remand, of a PTAB decision in an inter partes review that had invalidated a key claim in a patent infringement action brought by the client.
Prior to entering private practice, Gary practiced for eight years as in-house patent counsel at DuPont, focusing on polymer-based coating products, agricultural chemicals and pharmaceuticals. Presently, Gary serves as an adjunct professor at Drexel University Thomas R. Kline School of Law, teaching a course of appellate advocacy.
