Filing of biological sequence listings forming part of the international application
For international applications filed on or after July 1, 2009, the following applies:
- You do not have to pay page fees (fees for additional pages over 30) for biological sequence listings filed in ST.25 text format as part of an international application in electronic form.
- However, you must pay full page fees for all pages of a biological sequence listing filed in image format as part of an international application in electronic form.
- You must pay full page fees for biological sequence listings filed on paper.
Note: Mixed mode filings (former part 8 of the administrative instructions) are no longer allowed.
Before you access the secure PCT e-filing service, you must first get your login credentials from Innovation, Science and Economic Development Canada. If you already have an account, you may log in.

WIPO’s digital certificates
To file an international application electronically, you need a digital certificate. You can apply for a WIPO Customer Certification Authority certificate online.
Alternative arrangements for filing international patent applications
This section describes alternative ways to file international patent applications in case:
- a failure occurs in any component of CIPO’s server that prevents you from completing your filing; or
- a failure occurs in any component of your system that prevents you from completing your filing.
In case of the above, clients are advised to transmit their application to CIPO by facsimile.
Should either of these things happen during your filing, we advise you to send your application to CIPO by facsimile.
You must address your facsimile to the Commissioner of Patents and use the following fax numbers:
- 819-953-CIPO (2476) or
- 819-953-OPIC (6742)
Facsimile correspondence that is sent to any number other than those indicated above, including those of a designated establishment, will be considered not to have been received.
Your electronic transmittal report constitutes acknowledgement that CIPO received the correspondence.
When you send a document by facsimile that also has a fee requirement, you should show your preferred mode of payment clearly on the covering letter. This will help expedite your payment.
For correspondence delivered electronically, including facsimile, we consider it 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. For correspondence delivered on a day when CIPO is closed for business, we consider it received on the next day CIPO is open for business.
Method of payment
You can pay using a credit card or by deposit account.
