Practice Notice Issued for Trademark Priority Claims
On September 2, 2010 the Canadian Intellectual Property Office ("CIPO") issued a Practice Notice to provide guidance on the use and interpretation of (Paris Convention) priority claims in accordance with the Trade-marks Act (the "Act").
Priority claims, which are available within six (6) months of the after the date on which the earliest application was filed for registration of the same or substantially the same trademark for use with the same kind of wares or services (the "Priority Period"), allow trademark applicants to essentially 'back date' the date of subsequent filings to the date upon which the original application was filed. Claims for priority may be submitted in the following ways:
1. including the claim in an application at filing within the Priority Period;
2. by amending a previously filed application to include the claim, provided the amendment is submitted within the Priority Period; or
3. by filing a separate declaration in respect of an application within the Priority Period.
A priority claim must reference the date of, and country where, the initial application was filed and, where an error has been made an Applicant may only correct those claims within the Priority Period. The Trade-marks Branch has indicated that a priority claim need not include the application number in the priority claim - however, such applicants may be required to provide a certified copy of the earlier application. If an error has been made in the application number referencing the earlier filed application, the Trade-marks Branch has indicated that the number may be corrected at any time before registration.
