About Stuart C. Ash

Trademarks are the core of Stuart C. Ash's work, from getting a mark registered to keeping it protected and well managed, both at home in Canada and abroad. Ash is a partner in Gowling WLG's Ottawa office, practising as a trademark lawyer who's also a registered trademark agent. A second strand of the practice covers deals where intellectual property is sold, transferred or licensed, and trademark licence agreements get particular attention there.

Clients come from all sorts of industries. On one side there are local tech companies; on the other, global media and entertainment businesses. Ash also acts for companies in consumer goods and financial services, and for food and health product makers.

Ash earned an LLB at the University of Manitoba and was called to the Ontario bar in 1996. At Gowling WLG, Ash once led the firm's Canadian Trademarks Group. World Trademark Review has included Ash in the WTR 1000 since 2013, and The Best Lawyers in Canada 2027 recognizes Ash for intellectual property law.

You'll often find Ash at a podium or in print on IP transaction issues. When Canada's amended Trademarks Act was on its way in, those talks went well past Ottawa, with stops in New York, Austin, Phoenix, Milwaukee and Melbourne, Australia.
