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 on the international filing fee.
Filing of Sequence Listings Forming Part of the International Application
For international applications filed on or after July 1, 2009:
- No page fees are payable for sequence listings filed in ST.25 text format as part of an international application filed in electronic form.
- Full page fees are payable for all pages of a sequence listing filed in image format as part of an international application in electronic form.
- Full page fees are payable for sequence listings filed on paper.
ATTENTION: Mixed mode filings (former Part 8 of the Administrative Instructions) are no longer permissible.
International patent applications have to be prepared using the latest version of WIPO's PCT-SAFE software.
Any support required regarding usage of the PCT-SAFE software or obtaining a digital certificate should be requested from the WIPO PCT-SAFE helpdesk.
If you need assistance to upload or make payments for international patent applications through this website, please contact CIPO's Client Service Centre. To report a technical problem, please complete the Problem Report form.
WIPO's Digital Certificates
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.

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