Jennifer represents clients in a variety of post-grant proceedings and patent litigation matters. She has substantial experience before the Patent Trial and Appeal Board, including inter partes reviews, post-grant reviews, patent appeals, and reexaminations, leading to her being named among the Top 50 Women in PTAB Trials. To date, Jennifer has served as lead or back up counsel in 35 PGRs, making her the most experienced PGR lawyer in the country, and has served as lead and backup counsel in many IPRs. Jennifer has achieved favorable results for clients in patent suits, including obtaining multiple decisions of patent ineligibility under Section 101 from both the PTAB and the Court of Appeals for the Federal Circuit.

Jennifer also has over 15 years of patent prosecution experience across a wide range of technical fields, including computer software, internet technologies, RFID, and life sciences and medical devices.

In addition to providing legal services for her clients, Jennifer has been a Lecturer-in-Law at the University of California, Davis School of Law, and has lectured on topics related to patent law at the University of California College of the Law, San Francisco and Santa Clara University School of Law. She also was a member of the faculty at the Practising Law Institute, and co-chair of the annual Fundamentals of Patent Prosecution boot camp for over a decade.

During law school Jennifer was editor-in-chief of the Santa Clara Law Review, and upon graduation was awarded both the faculty-selected Mabie Award for Outstanding Graduate and the peer-selected Graduating Student of the Year.

Prior to rejoining Fenwick, Jennifer was general counsel with Apercen Partners LLC, serving as sole counsel for seven entities spanning a breadth of legal issues, including IP, employment, contract, securities, tax, and general compliance matters.
