He is also experienced in Patent Trial and Appeal Board (PTAB) proceedings, having prosecuted a number of AIA trials before the USPTO. Mr. Kim is admitted to practice in Arizona, New York, and New Jersey, and before the U.S. Patent and Trademark Office. He earned his J.D. from Rutgers University School of Law in Newark in 1994.
