Login to PCT e-Filing


Welcome to CIPO's International Filing e-service, called PCT e-Filing.

With this online service, users are able to submit international patent applications to the Canadian Intellectual Property Office (CIPO). PCT e-Filing allows users to pay the prescribed filing fees on-line and to receive the filing date and international application number immediately.

Applications filed using PCT-SAFE e-filing receive a fee reduction (PDF 41.7 KB) on the international filing fee.

Applications prepared using WIPO's ePCT online service and filed through CIPO's International Filing e-service receive a fee reduction (PDF 41.7 KB) on the international filing fee.

Using WIPO's ePCT Online Service with Canada as the Receiving Office

Step 1 - Prepare the PCT application using WIPO's ePCT online service:

  • Login to WIPO's ePCT Portal;
  • Prepare the PCT application, validate it and download the e-filing package (.zip file);
  • Save the .zip file (contains a .zg1 file needed in Step 2).

Step 2 - Submit the PCT application to CIPO with CIPO's PCT e-Filing service:

  • Login to CIPO's PCT e-Filing service;
  • Extract the .zg1 file from the .zip file obtained in Step 1;
  • Transmit the .zg1 file to CIPO through CIPO's PCT e-Filing service.


The payment of fees is not done in Step 1 through WIPO's ePCT Portal. Payments may be made directly to CIPO by credit card or deposit account in CIPO's PCT e Filing at Step 2 or via other means.

In order to file an international application electronically, a digital certificate is required. You can apply for a WIPO Customer Certification Authority (CA) certificate online.

Alternative Arrangements for Filing International Patent Applications

This section describes alternative arrangements available for filing international patent applications in case:

  • A failure occurs in any component of the CIPO's server, which prevents successful completion of filing.
  • A failure occurs in any component of the client's system, which prevents successful completion of filing.

In case of the above, clients are advised to transmit their application to CIPO by facsimile.

Facsimiles must be addressed to the Commissioner of Patents, and sent using the following numbers (facsimile equipment of CIPO's mailroom):

  • 819-953-CIPO (953-2476) or
  • 819-953-OPIC (953-6742)

The electronic transmittal report will constitute the acknowledgement that the correspondence has been received.

Facsimile correspondence that is sent to any facsimile number other than those indicated above, including those of a designated establishment, will be considered not to have been received.

When submitting a document by facsimile that also has a fee requirement, notification of the preferred mode of payment to be applied should be prominently displayed on the covering letter to ensure expedient processing.

Correspondence delivered by electronic means of transmission, including facsimile, will be considered to be received on the day that it is transmitted if it is transmitted and received before midnight, local time at CIPO on a day when CIPO is open for business. When CIPO is closed for business, correspondence delivered on that day will be considered to be received on the next day on which CIPO is open for business.

Method of Payment

Payments may be made by credit card or by deposit account.
