About Markwell Clarizio LLP
Markwell Clarizio LLP is a small Toronto firm that practices intellectual property litigation and drug regulatory law almost exclusively. It represents pharmaceutical, biotechnology, and medical device companies in patent infringement and validity actions, trademark disputes, and proceedings before the Federal Court and the Patented Medicine Prices Review Board, along with legal opinions and due diligence work. The firm started in 2023 as Markwell LLP and expanded that October when patent lawyer Dino Clarizio joined as a partner, which led to the rebrand to Markwell Clarizio LLP.
Founding partner Jason Markwell was called to the Ontario bar in 1999 after a science degree from Queen's University and a law degree from Osgoode Hall Law School. Dino Clarizio, called to the bar in 1991, has practiced only in intellectual property law since then and co-authors two standard references on Canadian patent law, including Hughes and Woodley on Patents. Several of the firm's younger lawyers and students hold their own science degrees, in biochemistry, biology, and engineering, which fits a docket built around technical patent files.
