In over 20 years of trying intellectual property cases and counseling clients, Mr. Rich has built broad experience in dealing with complex and difficult issues. He has successfully litigated in Federal and state trial and appellate courts throughout the United States, in cases involving patent, trade secret, trademark, copyright, and other commercial issues. He has also represented clients before the United States Patent and Trademark Office in inter partes review, reexamination, and interference proceedings, as well as in arbitrations around the world. But his experience is not limited to adversarial proceedings; Mr. Rich has worked closely with clients to avoid litigation when appropriate.

He is accomplished in all facets of trial and appellate litigation, ranging from pretrial seizures and preliminary injunction proceedings to bench and jury trials, appeals, and certiorari petitions. He works closely with clients to find the best solutions to intellectual property disputes.
