Overview

What is Trademark Opposition?

Once a trademark is accepted, it is published in the Trade Marks Journal. Any person can oppose it within four months of publication by filing a notice of opposition in Form TM-O. The applicant must then file a counter-statement, after which both sides submit evidence and the matter may go to a hearing.

Whether you want to stop a confusingly similar mark or protect your own application from an opposition, our experts prepare the filings, evidence and arguments you need at each stage.
