Alexandra M. Leeper, Partner, Cooley LLP

Alexandra M. Leeper is a partner in Cooley's intellectual property litigation group, focusing on complex patent disputes for technology companies. Her practice involves a diverse range of technologies, including augmented and virtual reality, network communications hardware and software, consumer electronics, and social media. Leveraging a master's degree in engineering, she handles technically demanding cases through all stages of litigation, from pre-suit analysis to trial and appeal.

Consistent with the provided case data, Leeper's practice is primarily focused on defending operating companies in patent infringement suits. Her only tracked case, NantWorks, LLC et al. v. Niantic, Inc., was a defense-side representation. This focus is further evidenced by her role as a team lead in securing a significant victory for NETGEAR in the District of Delaware, which resulted in a dismissal with prejudice and summary judgment on multiple patents in late 2025.

Leeper has spent her entire legal career at Cooley, which she joined in 2016 after clerking for Judge Lucy H. Koh in the U.S. District Court for the Northern District of California and Judge Michelle T. Friedland in the U.S. Court of Appeals for the Ninth Circuit. While her firm biography notes experience before the U.S. Patent and Trademark Office, specific appearances in IPR or other PTAB proceedings are not publicly documented.

She earned her J.D. from Stanford Law School and also holds both a Master of Science in Management Science and Engineering and a Bachelor of Science in Mathematical & Computational Science from Stanford University. Leeper is admitted to practice in California.
