Sherry (Hanhui) Li focuses on patent litigation and client counseling, leveraging her technical background in computer science and engineering. She advises on complex intellectual property (IP) disputes involving artificial intelligence (AI), software, semiconductors, batteries, and medical devices, and has experience assisting international clients in matters before U.S. district courts and the Patent Trial and Appeal Board (PTAB) of the U.S. Patent and Trademark Office (USPTO).

Sherry advises clients on patent litigation, client counseling, and strategic IP matters, drawing on her computer science and engineering background to translate complex technologies into clear, practical guidance. Her experience includes infringement and invalidity analyses; discovery; motion practice; and cross-border strategy across an array of electrical and software technologies. 

 

Before entering the legal field, Sherry was a software engineer at a multinational information technology corporation, where she built and deployed data systems to improve product reliability and user experience. She is the named inventor on a Chinese patent and has published research on optimizing energy conversion processes, reflecting her hands-on work in miniaturizing electrical and mechanical systems for efficiency.
