Trademark opposition deadline calculator
Enter the date of the Trade Marks Journal that published the mark. You’ll get the last date to file a notice of opposition (Form TM-O), the days left, and a reminder for your calendar.
Your opposition deadline
Estimate only. Confirm the date in the official Trade Marks Journal and file well before the deadline. This is not legal advice.
Each block is one week of the 4-month window.
The reminder fires 30, 7 and 1 day before the last day. Some calendar apps, Google Calendar among them, drop reminders from imported files, so check yours after importing.
How the deadline is worked out
Anyone can oppose a trademark within 4 months of the date of the Trade Marks Journal that advertised it (section 21(1) of the Trade Marks Act, 1999). We add calendar months to the journal date. The journal date itself isn’t counted, so the last day falls on the same date in the end month: a mark published on Monday, 2 November 2026 can be opposed until Tuesday, 2 March 2027.
If the end month is shorter, the last day of that month is used. A mark published on 31 October can be opposed until 28 February, or 29 February in a leap year.
The period is counted from the publication date shown on the Journal. If you’re in doubt about which date applies, file earlier.
Can the deadline be extended?
No. The period is written into the Act itself, and the Registrar has no power to extend it. The old system of 3 months plus a one-month extension ended on 8 July 2013, when the 2010 amendment to the Act came into force.
Online filings get no holiday extension, because e-filing is open at all hours. File online before the date shown.
What filing costs
A notice of opposition is filed on Form TM-O. The official fee is ₹2,700 per class opposed when filed online (₹3,000 on paper), and it’s the same for everyone. A trademark agent’s or advocate’s fees are extra.
