Matthew D Powell

Partner at Gilbert’s LLP

Matthew D Powell is a patent prosecutor and a professional engineer. He leads the patent prosecution group at Gilbert's LLP and is known to be as comfortable at clients’ workbenches as he is in their boardrooms.

Mr Powell is retained by companies developing products and services involving telecoms, computing, digital currency, image processing, facial recognition, semiconductors, AI, magnetic resonance imaging, location-based services, virtual reality, energy storage, advanced materials, construction, vending and numerous others. He often works alongside patent litigators to consult on the strength and scope of patents from a prosecutor’s perspective.

Mr Powell earned his degree in electrical and computer engineering in 1997. He then worked as a software developer and inventor before shifting into full-time patent work in 2002. In 2003 he was awarded the Marie F Morency Memorial Prize for Canada’s highest score in patent drafting during his qualifying examinations. In 2012 he was appointed by the commissioner of patents to the Patent Agent Examination Board. He has maintained a Recommended Individual rating in the IAM Patent 1000 since 2014 and a listing in the prestigious IAM Strategy 300 since 2016.

Mr Powell has enjoyed teaching patent drafting at some of the International Federation of Intellectual Property Attorneys’ patent drafting tutorials and speaking to audiences about IP law and practice at seminars and courses held by the Law Society of Upper Canada, the Ontario Bar Association, Ontario College of Art and Design University, Sheridan College, Osgoode Law School and the Intellectual Property Institute of Canada.
