Please note that you cannot use the form below to file a Patent Cooperation Treaty (PCT) International Patent Application. For an international application, see the instructions on the PCT e-filing page.

2. In order to receive a filing date, your application must contain:

A patent application consists of many parts, only a few of which are required to be submitted to the Office to obtain a filing date. However, all the parts of the patent application must be submitted soon after the filing date in order to be compliant with the prescribed requirements of the Patent Act and the Patent Rules. You are encouraged to submit the other parts of the application at the time of filing.

Other compliance requirements:

Application Fee:

The application fee is not a requirement to establish a filing date. If an applicant does not pay the application fee on the filing of the application, they will be required to pay a late fee.
