Lisa J. Pirozzolo

Lisa J. Pirozzolo is a partner and former co-chair of the Intellectual Property Litigation Practice Group at Wilmer Cutler Pickering Hale and Dorr in Boston. Her practice concentrates on intellectual property and commercial litigation, with a particular emphasis on the life sciences sector. She handles patent infringement and licensing disputes across a range of technologies, including pharmaceuticals, medical devices, and gene expression technology. Pirozzolo has been with WilmerHale and its predecessor firm, Hale and Dorr, since 1993.

The attorney's work appears to be balanced between representing patent holders and accused infringers. While the tracked case list shows her representing the defendant Luxottica in a patent dispute over smart-glasses technology, other publicly available information highlights her role on the plaintiff side. Notably, she was part of a trial team that secured a significant victory for Exelixis in a Hatch-Waxman litigation, protecting the patents for its cancer drug Cabometyx®. Her experience covers all phases of litigation, including trials and appeals.

Ms. Pirozzolo's practice also includes post-grant proceedings before the Patent Trial and Appeal Board (PTAB). For example, she was listed as counsel for patent owner Genentech, Inc. in an inter partes review (IPR) proceeding. She is recognized as a leading practitioner in patent and life sciences litigation by numerous legal publications.

Admitted to the Massachusetts bar, Ms. Pirozzolo earned her J.D., cum laude, from Cornell Law School and a B.A. from Yale College. Following law school, she clerked for the Hon. Franklin S. Billings, Jr. in the U.S. District Court for the District of Vermont.
