Alternative arrangements for filing international patent applications

This section describes alternative ways to file international patent applications in case:

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:

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.

You can pay using a credit card or by deposit account.
