When a Trademark is advertised in a Trademarks Journal (an Official Publication) any person may oppose the registration by filing the prescribed FORM TM–5 stating the grounds for opposition. The prescribed FORM TM-5 should be filed within 3 months from the date of publication in the Trademarks Journal. Further, the notice of opposition should be filed in the Office of the Registry where the application was filed.

     For example:- If the advertised application is filed in the Chennai Registry and if the opponent is from Kolkatta, the opposition should be filed before the Chennai Registry.
