She is an exemplary attorney.; Anne is knowledgeable and smart, quick on her feet, and extremely industry and business -savvy. – Chambers USA, 2022

When biotech innovations and licenses lead to conflict—or companies need advice avoiding it—companies trust Anne Li for outside-the-box strategies. She represents clients whose groundbreaking products and services raise complex legal questions at the nexus of competitors and collaborators, including those times when one shifts to the other. She has significant experience in the biotech, pharma, life sciences, and medical device sectors, handling high-stakes litigation in patent, trade secret, and licensing disputes.

Anne frequently advises biotech, biologics, pharmaceutical, medical device, and technology companies on all aspects of intellectual property law—patents, trade secrets, unfair competition, trademarks, contract disputes, and licenses. Her goal is always to reach a good business resolution. But when that is not possible, she zealously advocates for her clients in district court, at the International Trade Commission, at the U.S. Patent and Trademark Office, or anywhere the case takes her. She has successfully represented companies in bet-the-company litigations, often scoring key wins long before trial, resulting in favorable settlements.

Companies rely on Anne to help them navigate the intersection of intellectual property and business because she provides in-house counsel with patent, unfair competition, and trade secret advice that is practical and actionable. She takes time to learn a client’s business—from biotech startups to multibillion-dollar pharmaceutical companies and everything in between—so she can help them develop bespoke strategies that work for their unique situations.

Clients also appreciate Anne’s ability to match legal strategies with their risk tolerance and business objectives. Her approach is informed by her commitment to developing long-standing relationships with in-house counsel and her knowledge of the industry and related technologies.

Anne is co-chair of Crowell’s Life Sciences Practice Group and a member of the Pro Bono Committee.
