After advertisement in the Trademark Journal, any person may oppose the registration of a trademark within four months under Section 21 of the Trade Marks Act.
Filing an opposition
File Form TM-O, with grounds of opposition, such as prior use, the existence of an earlier or well-known trademark, or a likelihood of confusion arising from similarity. The applicant files a counter-statement; evidence stages and hearings follow.
Defending your application
Respond with proof of use, coexistence agreements, or distinctiveness. DuxLegis represents both opponents and applicants throughout trademark opposition proceedings.
