Trademark opposition: deadline, process and counter-statement
A trademark opposition challenges an advertised trademark. It is filed in Form TM-O within four months of publication in the Trade Marks Journal.
Short answer
A trademark opposition is a formal challenge by any person to the registration of a trademark that has been accepted and advertised in the Trade Marks Journal. Under section 21 of the Trade Marks Act, 1999, a notice of opposition in Form TM-O must be filed within four months of the advertisement date.

How opposition proceedings work
Once a notice of opposition is served, the applicant must file a counter-statement within two months, failing which the application is treated as abandoned. The parties then file evidence by affidavit in turn: the opponent's evidence in support, the applicant's evidence in support of the application, and the opponent's evidence in reply. The Registrar hears both sides and decides whether the mark should proceed to registration. Either party can appeal the decision to the High Court. Proceedings can take a long time, and parties often settle through coexistence agreements or amendments to the specification.
Common grounds of opposition
An opponent can rely on absolute grounds under section 9 or relative grounds under section 11 of the Act, along with general objections. The grounds most often raised in practice are these.
- Similarity to an earlier registered or used mark, likely to cause confusion
- Prior use and reputation of the opponent's mark
- The mark is descriptive, generic or lacks distinctiveness
- The application was made in bad faith
- The applicant is not the proprietor of the mark
Why it matters for startups
Monitor the Trade Marks Journal or use a watch service so you can oppose marks similar to yours within the four-month window, which cannot be extended. If your own application is opposed, file the counter-statement on time and gather evidence of your use and reputation, such as invoices, marketing and media coverage. Missing a deadline can cost you the mark.
