Eileen M McMahon

Eileen’s market-leading experience, practical advice and industry insight in intellectual property and regulatory law make her a go-to advisor for clients in Canada and the United States.

Chair of Torys’ Intellectual Property and Food and Drug Regulatory practices, Eileen is one of a handful of Canadian lawyers who advise on regulatory clearance and intellectual property protection of products. Across sectors—including life sciences, agribusiness, regenerative medicine and stem cells, cannabis and more—Eileen helps clients identify IP and regulatory assets, obtain and maintain market exclusivity, exploit IP assets and enforce their IP rights.

Eileen is a registered patent and trademark agent in the United States and Canada and is adroit at navigating the issues at play in cross-border matters. She is also a Certified Licensing Professional of the Licensing Executive Society (LES) (2011-2014), United States and Canada. This certification is issued only to persons who have met the requirements for licensing professionals, established by CLP, Inc., under the guidance of the LES. Fewer than 1% of all attorneys have this certification, making Eileen a specialized resource for clients.
