With 35+ years of experience as a patent attorney, Bill’s practice involves all aspects of domestic and foreign patent preparation, prosecution and assertion, including dispute resolution. He regularly counsels clients on the development and management of patent portfolios. Bill’s practice includes counselling on how to protect various aspects of inventions and monetize them by sale and licensing. 

Bill has managed intellectual property matters in many technical disciplines including manufacturing, metallurgy, chemistry, medical devices and aeronautics.  His background in industry plus his diverse experience in writing and prosecuting hundreds of patents have enabled Bill to spot the strengths and weaknesses in a patent when a dispute or enforcement issue arises. 

He has an affinity for working with emerging entities whose value can be enhanced by effective intellectual property portfolio creation and management to help his clients’ businesses succeed.  In one case, he introduced two separate clients – a physician and an entrepreneur – and brought them together to develop and protect medical devices to treat patients and enhance the quality of their lives.

Bill is a member of the Federal Bar Association – Eastern District of Michigan Chapter and currently serves as a co-chair of the Intellectual Property Law Section.  He is a former council member of the Aviation Law Section of the State Bar of Michigan.  Bill is a Fellow of the Michigan State Bar Foundation and a Master of the Bench (American Inns of Court).  Bill also served on the steering committee that formed the Michigan Intellectual Property American Inns of Court Chapter and was its President (2017-18). He was an adjunct professor of patent law at the University of Detroit Mercy School of Law.

He has been appointed as an Expert Adviser and Facilitative Mediator in the Federal District Court, Eastern District of Michigan.

Outside the office, Bill enjoys flying his Beechcraft Debonair airplane, skiing, playing golf and tennis, working out and travelling to England, his birth place. He and his wife Candyce count Vail Colorado and Ft Lauderdale as favorite haunts.
