Scholar. Fighter. Copyrighter.

Reagan is a trademark and copyright enforcer. Skilled in cross-examinations, laws of evidence and procedure, negotiations and legal argument, Reagan solves problems and protects high-value intellectual property. 

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. Trademark oppositions, section 45 non-use cancellation challenges, and trademark infringement and copyright infringement matters are all in his wheelhouse.

Outside the courtroom, Reagan is seasoned in trademark clearance opinions, the prosecution of trademark filings, 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.
