Fan (Frances) Zhang

Fan (Frances) Zhang is a patent litigation attorney whose tracked experience includes representing operating companies in intellectual property disputes. Her practice areas, based on case involvement, appear to include technologies related to mobile device data management and wireless communication. She is associated with Sheppard, Mullin, Richter & Hampton LLP.

Zhang's sole tracked appearance is as counsel for the plaintiff in Samsung Electronics Co., Ltd. v. Headwater Research LLC. While the broader litigation involving Headwater Research LLC against Samsung in district court primarily saw Samsung as a defendant in patent infringement suits concerning mobile technology and Wi-Fi standards, her "plaintiff" side appearance for Samsung suggests involvement in actions such as declaratory judgment suits or petitions to challenge patent validity. This is further supported by her documented role as counsel for Samsung Electronics Co., Ltd. as a petitioner in multiple inter partes review (IPR) proceedings against Omni Medsci, Inc. (e.g., IPR2025-01250) before the Patent Trial and Appeal Board (PTAB). This indicates a focus on representing operating companies in defending against patent assertions, often from non-practicing entities, through offensive invalidation strategies.

She has experience with PTAB proceedings, having represented Samsung in IPRs.

Fan (Frances) Zhang is admitted to the California Bar under license #324347. Her license status is currently inactive as of March 30, 2026.
