Responding to a Section 45 Notice

The owner of a trade-mark registration (or its representative for service) will receive a Section 45 Notice directly from the Registrar, indicating a three-month deadline for responding thereto.

If a registrant does not already have a trade-mark agent, it is strongly recommended to hire one at this point. Section 45 proceedings may be complex and can cost considerable time and money. A trade-mark agent should be chosen carefully; choose someone with proven expertise in this field. A list of trade-mark agents is available online or by contacting the Client Service Centre.

A registrant, or preferably its trade-mark agent, should take one of the following actions within the three-month time period, failing which its registration may be expunged:

  1. File one or more affidavits or statutory declarations and send a copy to the requesting party; or
  2. Request an extension of time for the filing of evidence and pay the prescribed fee; the request must:
    1. identify the trade-mark registration by number and trade-mark;
    2. provide sufficient reasons to explain why the extension of time is required;
    3. indicate the method by which the prescribed fee (see Payment of prescribed fees)
    4. cc. the requesting party.

Form of evidence to file

See Evidence in Practice in Section 45 Proceedings.

Note the following:

  • Evidence must be filed in the form of affidavits or statutory declarations;
  • Evidence cannot be filed by fax;
  • Evidence is not subject to cross-examination.

The exact nature of the evidence to be filed depends on the individual case. A registered trade-mark agent can assist you in determining what evidence is needed in order to put your best case forward.

The evidence must be filed with the TMOB and a copy sent to the requesting party within the set deadline.
