This notice supersedes the one of September 18, 2015.

As of September 22, 2015, biological sequence listings forming part of the description of new applications entering the national phase are automatically obtained from the World Intellectual Property Organization (WIPO) in the format submitted during the international phase.

As a result, clients will no longer be required to provide these documents at the national entry phase.

However, if we receive a duplicate sequence listings from the applicant of the one on file from WIPO, we will:

  1. 1. check the WIPO sequence for defects:
    1. 1.1 if there are no defects, we will use the WIPO sequence for examination purposes;
    2. 1.2 if there are defects, we will assess the submitted duplicate;
      1. 1.2.1 if there are no defects in the submitted duplicate, we will use the submitted duplicate for examination purposes; and
      2. 1.2.2 if there are defects in the submitted duplicate, we will send a requisition to the applicant.

Please note that any amendments to the biological sequence listings submitted after the national entry phase will still have to be provided as a Voluntary Amendment to the Canadian Intellectual Property Office.

Should you have any questions, you are invited to communicate with Andrée Patry, Manager – Operations Sector, at 819-635-3557 or at
