About Chad

Chad has earned a global reputation for successfully protecting the intellectual property rights and assets of pharmaceutical companies in high-stakes patent litigation in the United States and internationally. For his clients, such cases are not mere inconveniences — they are make-or-break disputes that determine returns on multibillion-dollar investments and decades of research.

Over the course of his career, Chad has represented clients in disputes involving some of the leading drugs on the market, including name brands such as SOVALDI®, HARVONI®, EPCLUSA®, RANEXA®, VEMLIDY®, DESCOVY®, ODEFSEY®, and DESCOVY for PrEP® (Gilead Sciences); LATUDA® and APTIOM® (Dainippon Sumitomo Pharma Co. Ltd./Sunovion);  ZORVOLEX® and VIVLODEX® (Iroko Pharmaceuticals); COREG®  and FLOVENT® (GlaxoSmithKline). Many of these cases are global in nature, often involving multiple jurisdictions and major markets in Europe, North America, and the Asia/Pacific region. Despite the scale of these matters, Chad is known for his approachability, pragmatism, legal and business acumen, unwavering dedication to his clients, and unflappability in even the most challenging of circumstances.

Chad’s trial experience is unparalleled. He has served as lead trial attorney or member of the trial team in nearly two dozen trials, including numerous Hatch-Waxman cases. Chad is equally well-versed in representing clients in post-grant proceedings before the U.S. Patent Trial and Appeal Board and in opposition proceedings before the European Patent Office. Drawing upon his experience as a Federal Circuit clerk, he has played a key role in hundreds of appeals.

Chad draws on his litigation experience, extensive network of scientific and business experts, and detailed knowledge of his clients’ companies to provide strategic legal counsel on a wide range of business matters. Able to communicate complex ideas in clear language, he speaks and writes frequently on issues such as biosimilars and generics, Hatch-Waxman litigation, Markman hearings, and biotechnology and pharmaceutical patent due diligence. Chad also teaches life sciences trial and patent practice courses around the country.
