Hanyong Lee


Leveraging the rare combination of training and practices in Korea and in the U.S., Hanyong Lee offers clients over 15 years of experience with IP management, licensing and litigation. Early in his career, Han worked at a major law firm in Korea as a patent attorney, and later at one of the largest Internet companies in Asia, Naver, where he was the lead in-house IP counsel founding and heading its IP department. 

Since joining Ropes & Gray in 2008, Han has litigated numerous U.S. patent infringement matters in the federal courts and before the International Trade Commission in both defensive and offensive actions. Han has experience in all stages of litigation, ranging from pre-suit investigations to pleadings, infringement and invalidity analyses, fact and expert discovery including e-discovery, and claim construction as well as pre-trial, trial and post-trial proceedings. His experience also includes mediation and settlement of IP disputes.

In addition to IP, Han has significant experience in compliance and government enforcement matters.  His practice includes advising clients on internal investigations, due diligence, and compliance programs, particularly with a focus on anti-corruption and anti-money laundering matters in Korea.  Han has conducted numerous internal investigations for multinational and private equity clients across different industries, including pharmaceutical, bio and cosmetic, finance, mobile and manufacturing.

Han was previously based in the firm’s New York office before relocating to Seoul in 2013. Prior to joining the firm, Han served as a Judicial Intern to The Honorable Susan G. Braden at the U.S. Court of Federal Claims.

Han is currently registered in Korea as a foreign legal consultant.
