Within two months from the advertisement of an application, any person may, upon payment of the required fee, file a statement of opposition with the Trademark Opposition Board. A proposed opponent need not show they would be adversely affected by registration. The effect of beginning an opposition is to bring the prosecution of the opposed application to a halt until the opposition is concluded.
An extension of the time to file the statement of opposition may be requested before or, sometimes after the expiration of the above limit. The timely request for an extension is a practical step as it will provide some time for the proposed parties to consider settlement.
An extension applied for after the expiration of the time limit or the time extended by the Registrar of Trademarks will not be granted unless the Registrar is satisfied that the failure to do the act or apply for the extension within that time or the extended time was not reasonably avoidable.
The Registrar may, within three months after the registration of a trademark, remove the registration from the register if the Registrar registered the trademark without considering a previously filed request for an extension of time to file a statement of opposition.
