Reagan is a trademark and copyright lawyer who represents clients through the full lifecycle of their IP journey. Whether helping a business select a new brand or enforcing long-established rights in court, Reagan is trusted to provide targeted strategies and legal interventions that make the most out of a client’s IP budget.

As a litigator, Reagan is known for his ability to distill complex problems into simple answers. He appears routinely before the Federal Court and Trademarks Opposition Board, while also making appearances on behalf of clients (successfully) before Ontario’s Superior Court of Justice and Court of Appeal.

Outside the courtroom, Reagan is seasoned in trademark clearance opinions, the prosecution of copyright and trademark filings, and licenses, assignments and other portfolio management strategies. Reagan is frequently called upon to speak on IP topics in the media and routinely contributes to academic legal discourse. His scholarly work is published in peer-reviewed journals from coast to coast, is cited in a leading property law textbook, and has been presented at major national conferences including the Congress of the Humanities & Social Sciences.

Prior to joining Smart & Biggar, Reagan had a celebrated career in Saskatchewan’s public sector and was a recipient of the Premier’s Award for Excellence in Public Service in 2016.
