Overview

Provided by Markwell Clarizio LLP

Markwell Clarizio LLP is an intellectual property litigation, drug regulatory litigation, and advisory firm in Toronto, Canada.

We help innovative pharmaceutical and biotechnology companies navigate the complex regulatory system governing the approval and sale of new drugs and biologic products in Canada, including data protection (data exclusivity), patent linkage (PMNOC Regulations), certificates of supplementary protection (patent term restoration), pricing, formulary interchangeability, product listing agreements, and advertising (PAAB). We represent clients at meetings with regulators, hearings before the Patented Medicine Prices Review Board (PMPRB), and on judicial review applications.

In our intellectual property litigation practice, we represent individuals and companies in patent infringement and impeachment actions, including cases under the Patented Medicines (Notice of Compliance) Regulations, trademark infringement and opposition proceedings, injunction motions, appeals, and interventions. We have a record of success in a number of important and precedent-setting cases.

We work with our clients to understand their commercial goals and to develop strategies that meet their needs. We discuss all possible means of dispute resolution before we recommend or commence litigation. We also explore alternative fee arrangements to help our clients achieve greater financial certainty. We keep our clients apprised of all material developments on a timely basis so that they can give instructions and focus on other business priorities.
