High-quality patents built to yield commercial value for clients

Focused primarily in the fields of electrical and computer engineering, Jeff works with businesses to draft and prosecute patent applications. He also provides insightful advice to clients on which patenting activities will best support their business objectives, particularly in view of other options such as trade secret protection and defensive publication.

Clients appreciate Jeff’s decisiveness, responsiveness, and overall approach to patents – that quality is more important than quantity. By focusing equally on process and purpose, Jeff produces well-drafted patents with real commercial relevance for his clients.

Domestic and international patent expertise coupled with diverse technical knowledge

Jeff also assists international companies and foreign firms seeking to file for patent protection in Canada, handling the Canadian patent prosecution with accuracy and efficiency. He regularly prosecutes patent applications in both the U.S. and Canadian patent offices, as well as in patent offices overseas through foreign associates, providing practical business-focused advice when the opportunity arises to add strategic value for the client.

Prior to entering the patent profession, Jeff pursued graduate studies in the field of electrical engineering, and he is named as a first author in papers published in IEEE Transactions on Information Theory and IEEE Transactions on Wireless Communications.

Jeff is a member of IEEE and Smart & Biggar’s representative on the IPIC Patent Practice Committee, which works to further improve policy and practice within the Canadian Patent Office and also reviews proposed changes to Patent Rules and practice.
