Dr. Susannah Gagnon focuses on IP matters, particularly those involving life sciences technologies. Susannah counsels clients regarding innovative technologies, particularly those involving life sciences, and assists with IP enforcement. Susannah has experience litigating Hatch-Waxman disputes for successful generic products, including in federal district court and before the Patent Trial and Appeal Board. Susannah also has represented clients in the agricultural technology and food science space, drawing on her background in structural biochemistry.

While completing her PhD research, Susannah focused on the structure-function characterization of multiple proteins: human ABO(H) blood group-synthesizing enzymes, monoclonal antibodies, as well as bacterial surface proteins. Her work on these topics resulted in multiple publications in high-impact, peer-reviewed scientific journals. Susannah has been the recipient of many awards, including international- and national-level scholarships, recognizing her research and academic leadership.

During her time at the University of Pennsylvania Carey Law School, Susannah served as a judicial intern to the Honorable Lee H. Rosenthal of the U.S. District Court for the Southern District of Texas, where she discovered her passion for litigation. At Penn Carey Law, Susannah also contributed to legal scholarship as a co-author with leading antitrust expert Professor Herbert J. Hovenkamp. Susannah is also familiar with construction contracts and arbitration disputes due to her part-time work assisting in-house counsel of a prominent North American steel solution provider prior to attending law school.
