William R. Boudreaux

“Effectively representing a client requires fostering an open and trusting relationship. My job is to address your issues and relieve your stress.”

Bill Boudreaux is an experienced pharmaceutical patent lawyer, bringing more than 20 years of experience from both in-house and private practice settings. Bill’s extensive in-house experience at major pharmaceutical companies gives him a unique perspective, allowing him to provide clients with practical, business-focused advice. He is known for his thoughtful, thorough approach and ability to anticipate client needs.

Bill represents a broad range of biotech and pharma clients ranging from Global Fortune 50 Companies to start-ups.  While at Eli Lilly and Pfizer, he was primary patent counsel for several late-stage and post-launch drug products, including four blockbuster drugs. He has extensive experience in global patent portfolio creation and management, pharmaceutical patent life-cycle planning and IP due diligence. Bill’s experience also includes freedom-to-operate studies, due diligence reviews, infringement/validity studies, and strategy and support for Hatch-Waxman litigation.

Whether providing advice to in-house counsel or business associates, Bill understands the importance of delivering legal advice in a distilled, business-focused way. In-house counsel appreciate that Bill has stood in their shoes. One lead lawyer at a global pharmaceutical company commented that it is rare to find someone like Bill who understands all aspects of her job—the legal issues, the pressures and relational dynamics.

A recognized leader in the life sciences space, Bill co-chairs Brinks Gilson & Lione’s Biotechnology and Pharmaceutical practice group and served on the firm’s Board of Directors and Executive Committee. He has been named a “Life Science Star” by Managing Intellectual Property magazine and a “Leading Intellectual Property Lawyer” by Leading Lawyers Network.
