Frequently Asked Questions

What is the difference between Canadian and US patent marking requirements?

While both jurisdictions now permit virtual marking, Canada requires the patent number to be associated with the product (physically or virtually), whereas the US allows 'patented' without numbers if virtual marking is used. Additionally, Canada's false marking provisions are criminal (Section 76) rather than civil liability based, and Canada does not have a qui tam false marking provision like the US previously did.

When can I start using 'Patent Pending' in Canada?

You may only mark 'Patent Pending' (or 'Demande de brevet en cours') after a Canadian patent application has been filed and you have received an application number from CIPO. Marking before filing constitutes false marking. The marking must cease if the application is abandoned or refused.

What are the penalties for false patent marking in Canada?

Under Section 76 of the Patent Act, false marking is a hybrid offense punishable by a fine up to $25,000. Additionally, the Competition Act may apply if the false marking constitutes misleading advertising to the public. Unlike some jurisdictions, there is no statutory damages provision for competitors to sue for false marking.

Does marking products in Canada affect my ability to collect damages in other countries?

No. Patent marking is jurisdictional. US marking requirements are governed by 35 U.S.C. § 287, and Canadian marking affects only Canadian infringement damages under Section 55(2). You must comply with each country's specific marking laws to preserve damages in that jurisdiction.
