Li’s practice focuses on protecting and defending companies’ intellectual property rights. She has litigated cases from inception through trial in federal district courts, in Section 337 investigations before the US International Trade Commission, and before the Patent Trial and Appeal Board. Li represents clients in all areas of intellectual property law, including patent, trademark, trade secret, and copyright.

Li began her legal career prosecuting patents and is registered to practice before the US Patent and Trademark Office. With a technical background in chemistry and extensive research experience in semiconductor materials, she has developed a deep awareness and understanding of the interplay between technology and law. She has represented technology companies in matters involving electronics, medical devices, semiconductors, software, pharmaceuticals and chemicals, consumer products, telecommunications, and manufacturing processes.

Prior to joining private practice, she interned for the Honorable Susan G. Braden at the U.S. Court of Federal Claims, she worked for several years as a policy and intellectual property specialist at the National Cancer Institute, and she also worked as an engineer in the semiconductor manufacturing industry.

Li frequently speaks and writes about intellectual property issues, and has published in Bloomberg Law, Law360, Intellectual Property Magazine, WardsAuto, and the 337 Reporter of International Trade Commission Trial Lawyers Association.

Recognizing the importance of pro bono service to the community, Li has worked on a variety of pro bono matters, representing clients seeking asylum, resolving child custody disputes and contract disputes, and assisting veterans. She previously interned at the Legal Counsel for the Elderly, providing free legal services to elderly residents of Washington, DC.

Li has been actively involved in a number of legal organizations and their committees, including the American Bar Association, the PTAB Bar Association, and the National Asian Pacific American Bar Association.
