Recent Cases

Intellectual Property Litigation

This was an appeal of a decision on a motion to strike certain portions of Bell Canada's Statement of Defence and Counterclaim. Initially the case management judge struck portions of Bell Canada's claims against our clients, the Plaintiffs/Defendants by Counterclaim and Aird & Berlis. That decision was appealed by Bell Canada. The Federal Court judge dismissed the appeal and determined that the case management judge was correct in dismissing certain claims against the Plaintiffs/Defendants by Counterclaim and Aird & Berlis including claims related to alleged misuse of copyright and unlawful means conspiracy.
