CIPO presents a common list of authorities for hearings of the Trademarks Opposition Board

CIPO presents a common list of authorities listing the decisions that are frequently cited in objection proceedings or notices under section 45 of the Trade-marks Act.

In proceedings before the Trademarks Opposition Board, a party that has decided to provide a compilation of case law to the Registrar is not required to provide a copy of a decision included in the common list.

However, the party is still required to include in its list of authorities the decisions found in the common list and that it intends to invoke.

If you have any questions or comments related to this common list of authorities, please contact our Client Service Centre.
