Appeals and Interventions

We are appellate lawyers. We have represented clients in complex intellectual property and drug regulatory cases before the Federal Court of Appeal and the Supreme Court of Canada, including seminal cases on patent damages, obviousness, utility, data protection, and patent linkage (PMNOC).

We represent clients on appeal and provide independent assessments of cases that were handled by other law firms at first instance. In that role, we help identify potentially reviewable errors, and assist in the preparation of notices of appeal, motion records, and written arguments (aka memoranda of fact and law).

In our intervention practice, we represent individuals, trade associations and public interest advocacy groups in important appellate cases affecting their interests. We accept a certain number of these cases on a reduced fee basis to ensure that important voices are able to be heard by the Court.
