Alex Chung's practice involves a mix of patent prosecution, counseling, and litigation in the areas of biotechnology and pharmaceuticals. He has extensive experience in procuring, managing, evaluating, enforcing, and defending patents and in providing strategic IP counsel to clients. Alex's practice includes the preparation and prosecution of patent applications, providing patentability, infringement, validity, and freedom-to-operate opinions, and conducting due diligence analysis on IP portfolios.

Prior to joining Jones Day in 2017, Alex successfully represented clients in patent infringement and Hatch-Waxman actions involving biotechnology and pharmaceutical patents in district courts and the United States International Trade Commission (ITC). He also has in-depth experience with inter partes review (IPR) proceedings before the Patent Trial and Appeal Board (PTAB). Alex has extensively represented U.S., European, Korean, and Japanese companies in the biotechnology and pharmaceutical industries.

Prior to attending law school, Alex worked as a postdoctoral fellow at the National Institutes of Health (NIH), where he investigated photoreceptor differentiation and designed switchable adeno-associated virus (AAV) gene therapy vectors for clinical trials. He is a co-inventor of a U.S. patent on RNA interference (RNAi) expression vector, which was commercially licensed to and is currently marketed by Thermo Fisher (f.k.a. Invitrogen).

Alex is a native speaker of Korean and regularly travels to Korea to visit clients.
