William D. Hall

Of Counsel


Bill Hall represents clients in all areas of intellectual property law and is a registered patent attorney with the U.S. Patent and Trademark Office.

In 2015, Bill was one of only two lawyers in Oklahoma to be honored with Lexology’s “Client Choice” award, which recognizes lawyers worldwide who provide excellence in client care and quality of service. In nominating him for the award, clients said “His efficiency in understanding inventions and his ability to guide inventors to imagine more than they disclosed are unparalleled” and “Bill has the capability to take the complex and distil it to an understandable product that is readily enforceable.” His achievements have also earned him inclusion in The Best Lawyers in America (patent law; trade secrets law).

Prior to joining McAfee & Taft in June 2001, he was senior counsel for Conoco, Inc., where he had worked for 10 years counseling clients in all areas of intellectual property and providing legal counsel relating to the Internet and computer law. 

Bill previously served on the executive committee of the Oklahoma Bar Association’s Intellectual Property Law Section representing each office, including a term as president in 1998.

In his leisure time, Bill enjoys taking friends on flights around Oklahoma in his Piper Arrow, scuba diving and slowly rebuilding a ’57 Chevy.
