Sangki Park

Sangki Park is a patent litigation attorney and Principal at Fish & Richardson P.C., where his practice encompasses a broad range of intellectual property matters. He focuses on patent procurement and litigation, offering counsel to domestic and international clients on offensive and defensive IP strategies. His technical experience spans diverse electrical, software, and mechanical arts, including telecommunications, semiconductors, medical devices, digital health, consumer electronics, networking, and standard-essential patents, such as video coding and haptic technology.

In terms of litigation strategy, Mr. Park primarily represents petitioners in post-grant proceedings before the Patent Trial and Appeal Board (PTAB), where he represents both petitioners and patent owners. While his two tracked appearances are on the plaintiff/petitioner side, his firm profile indicates he also handles the defense of IP rights in district courts and the International Trade Commission (ITC). Fish & Richardson is noted for its extensive experience in PTAB proceedings, and Mr. Park has co-authored insights on IPR considerations for foreign companies.

His notable representations include acting as Attorney for Petitioner in Apple Inc. v. Resonant Systems Inc. (IPR2024-00807), an IPR before the PTAB concerning haptic feedback devices. In this proceeding, the PTAB issued a Final Written Decision finding claims 2 and 3 of the challenged patent unpatentable. He also served as counsel for Eunsung Global Corp. in Eunsung Global Corp. v. HydraFacial LLC, a matter involving hydrodermabrasion systems where certain IPR petitions filed by his client were denied institution by the PTAB.

Mr. Park earned his J.D. from Washington University School of Law and holds a B.S. cum laude in Mechanical and Aerospace Engineering from Seoul National University. He is admitted to practice in Minnesota, the District of Columbia, before the U.S. Patent and Trademark Office, the U.S. District Court for the District of Minnesota, and the Korea Intellectual Property Office, having previously worked as a patent attorney in Korea.
