Readers will be saddened to hear that William L. Hayhurst QC passed away on February 27, 2011 after a long illness.  Bill Hayhurst was one of the leading IP lawyers of his generation and a prolific and oft-cited author of articles on IP.  He had a scholarly interest in intellectual property and gave generously of his time and knowledge to whoever sought it.

Bill attended Queen's University, graduating with the gold medal in electrical engineering. After obtaining a Master of Science degree from the California Institute of Technology in Pasadena and teaching in the Faculty of Electrical Engineering at the University of British Columbia, he read law at Osgoode Hall, where he was awarded the gold medal on graduation.

Bill Hayhurst practised law at Ridout & Maybee in Toronto for 40 years, specializing in intellectual property. He became senior partner and was counsel to the firm in retirement. While practising, for 21 years he taught the courses on intellectual property in the Faculty of Law at the University of Toronto.

He was past president and honorary member of the Intellectual Property Institute of Canada, and past president and life member of the Canadian Group of the International Association for the Protection of Industrial Property.

Sincere condolences are extended to his family.
