Bill Rooklidge practices in the area of intellectual property litigation and related counseling, with a focus on patent infringement litigation. He represents clients in a variety of industries, including communications, diesel engines, software, electronics, sporting goods, and financial services. He also has considerable experience in trademark litigation, enforcement of intellectual property through U.S. Customs and Border Protection, and mediation and arbitration of intellectual property disputes. He has extensive trial and appellate experience, including arguing many cases at the U.S. Court of Appeals for the Federal Circuit.

Prior to joining Jones Day in 2011, Bill represented a major search engine company as a co-defendant in a patent infringement suit alleging infringement of a patent related to a method for processing electronic messages by providing internet search advertising. The jury returned a verdict on the first day of deliberation in favor of the client and found that none of the three asserted claims were valid or infringed. He also represented the same internet search provider in defending another patent infringement charge and was successful on summary judgment. In addition, he represented a toy manufacturer in defending the appeal of a trademark opposition proceeding in the Federal Circuit, which affirmed the decision that the client had not abandoned the mark, and represented an owner of golf club patents in cases regarding knock-off club components.

Bill has served as president of the Orange County Patent Law Association and the American Intellectual Property Law Association (AIPLA). He has published and spoken extensively on patent issues.
