Nana Liu

Nana Liu is an associate in the Patent Litigation practice at Mintz, Levin, Cohn, Ferris, Glovsky and Popeo P.C., focusing on intellectual property litigation for life sciences companies. Her practice involves cases in federal district courts, the U.S. Court of Appeals for the Federal Circuit, and the International Trade Commission (ITC). She handles matters involving high-tech, biologic, and chemical innovations, including Hatch-Waxman pharmaceutical cases and Section 337 investigations at the ITC. While her tracked appearances include one plaintiff-side matter, her overall practice and recognition suggest a strong focus on representing complainants and patent owners seeking to enforce their intellectual property rights, although she has also represented defendant-appellees in appellate matters.

At Mintz, Ms. Liu serves as a key member of case teams, handling aspects from pre-suit diligence and discovery to claim construction, motion practice, and trial preparation. Her notable experience includes representing Glycosyn LLC as a complainant in an ITC investigation (Certain Human Milk Oligosaccharides and Methods of Producing the Same) that led to an Initial Determination finding infringement and recommending an exclusion order. She also successfully represented Kowa Company and its affiliates as appellees at the Federal Circuit, upholding the validity and infringement of two patents (Kowa Company, Ltd., et al v. Amneal Pharmaceuticals, LLC). Additionally, she has represented Innovative Foundry Technologies and GlobalFoundries in ITC semiconductor-related disputes, which resulted in resolutions.

Ms. Liu is actively involved in PTAB and IPR proceedings, having co-authored articles on PTAB statistics concerning Orange Book-listed and biologic patents, and providing tips for patent owners navigating IPRs. She is admitted to practice in California and Massachusetts. Ms. Liu earned her Juris Doctor from Northeastern University and holds a Bachelor of Arts in Biological Chemistry from Wellesley College.
