The exact word "TSI" is already on record at the Indian Trademark Registry under Application No. 7958971. If you intend to use a similar mark for similar goods or services, you should conduct a comprehensive availability search and consult a trademark attorney before filing. Registerkaro offers a free availability check followed by professional filing.

Indian registered trademarks are valid for 10 years from the date of registration and can be renewed indefinitely in 10-year blocks. TSI (App #7958971) is currently in status "Send To Vienna Codification" — renewal dates apply only after registration is granted.

If TSI is in the "Advertised before Acceptance" or "Accepted & Advertised" stage, you have a 4-month window from publication in the Trade Marks Journal to file an opposition (Form TM-O) at the same Trade Marks Registry office. Grounds typically include prior rights, descriptiveness or bad faith. Registerkaro can prepare and file a Notice of Opposition for you.
