Notice on filing of certified electronic priority documents to the Canadian receiving Office

With respect to Patent Cooperation Treaty (PCT) international applications and pursuant to PCT Rule 17.1(a), the applicant may submit to the Canadian receiving Office (CA/RO) electronic priority documents that are digitally signed with the certificate of one of the following issuing Offices:

  • National Institute of Industrial Property of Brazil;
  • National Institute of Industrial Property of Portugal; or,
  • United States Patent and Trademark Office.

Electronic priority documents may be uploaded into ePCT so that they will be contained in an ePCT filing package, together with the international application, for submission to CA/RO at time of filing through CIPO's e-filing using the normal two-step process. Alternatively, at the time of filing or post filing the electronic version of the priority document can be submitted to CA/RO on various electronic media as specified in Annex F of the PCT Administrative Instructions.
