About Nadine D'Aguiar Professional Corporation

Nadine D'Aguiar Professional Corporation is a solo intellectual property practice in Ontario, founded in 2011 by Nadine D'Aguiar, a lawyer, trademark agent, and patent agent. The firm describes itself as a "virtual" IP law practice, meaning it was built without a traditional bricks-and-mortar office; the model keeps overhead low and lets the practice work with clients wherever they are. D'Aguiar holds an LLB and a Bachelor of Science in Chemical Engineering, both from Queen's University, was called to the Ontario bar in 1997, and later qualified as a Canadian trademark agent in 2001 and a Canadian patent agent in 2005.

Before starting the firm, D'Aguiar worked in the intellectual property departments of several large Canadian law firms, and the practice now draws on more than 25 years combining private practice and in house experience. The work centers on trademark prosecution and portfolio strategy (the firm has handled more than 500 trademark applications and official mark requests since it opened) alongside technology licensing and health law contracts for hospitals and research institutes negotiating clinical study, collaboration, and data transfer agreements. D'Aguiar belongs to the International Trademark Association and the Licensing Executive Society, is an associate member of the Intellectual Property Institute of Canada, and previously served as chair of the Toronto Intellectual Property Group.
