Intellectual Property

At Lenczner Slaght, we recognize the vital importance of intellectual property in a complex and fast-moving global marketplace. Our success in negotiating favourable commercial outcomes in litigation matters extends as well to the resolution of technically sophisticated IP disputes on behalf of our clients.

We draw upon our firm's extensive courtroom experience as we represent clients in intellectual property matters in proceedings before the Federal Court, the Federal Court of Appeal, the Ontario Superior Court and the Ontario Court of Appeal. Our lawyers have also litigated IP cases in the U.S., and we regularly represent U.S.-based corporations on the Canadian aspects of disputes that span multiple jurisdictions.
