Any person — registered trademark owner or not — may file an opposition in India. Common grounds include similarity with your own mark, likelihood of consumer deception, bad faith filing, and absolute grounds under Section 9 of the Trade Marks Act.
Exactly 4 months from the date of publication in the Trade Marks Journal. This is a hard deadline — no extension is permitted. Missing it forfeits your right to oppose that application via this route.
Government fee for TM-O (opposition filing) is ₹2,700 per class. Our professional charges for filing an opposition start from ₹5,999. For defending an opposition (counter-statement + representation), charges start from ₹4,999.
