Trademark opposition: 4 months, not extendable.

Section 21(1) gives a fixed four-month window to oppose an advertised mark. Understand the stages — and never miss the date — with a weekly Journal watch.

The opposition stages

  1. 1

    Advertisement

    The accepted mark is published in the weekly Trade Marks Journal. The 4-month clock starts from the date of advertisement.

  2. 2

    Notice of opposition (Form TM-O)

    Any person may oppose within 4 months under s.21(1). This deadline is not extendable — miss it and the mark proceeds to registration.

  3. 3

    Counter-statement

    The applicant files a counter-statement, typically within 2 months of receiving the notice, or the application is deemed abandoned.

  4. 4

    Evidence & hearing

    Both sides file evidence by affidavit (Rules 45–47), followed by a hearing before the Registrar, who then decides the opposition.

Why the window is the most important date

Not extendable. Unlike many procedural timelines, the 4-month opposition window under s.21(1) cannot be extended. TM Watch treats it as the highest-priority deadline in the whole lifecycle: dated from the Journal advertisement, holiday-adjusted, and alerted on a 90 / 60 / 30 / 7 / 1-day schedule.

Frequently asked questions

How long is the trademark opposition period in India?
Four months from the date the mark is advertised (or re-advertised) in the Trade Marks Journal, under s.21(1) of the Trade Marks Act, 1999. This period is fixed and cannot be extended.
Who can oppose a trademark?
Any person — you do not need to own a registered or prior mark to file a notice of opposition, though a prior right strengthens the case. Common grounds are under s.9 (absolute) and s.11 (relative, e.g. similarity to an earlier mark).
What happens if I miss the opposition window?
If no opposition is filed within the 4 months, the mark generally proceeds to registration. Because the window is not extendable, a missed diary entry can mean losing the only easy chance to stop a conflicting mark — which is precisely what a Journal watch guards against.
How does TM Watch help with oppositions?
TM Watch searches the weekly Journal and runs a class-scoped scan of your whole portfolio against each issue, raising an alert on any mark advertised or cited against you. It also dates the opposition window from the advertisement and reminds you on a tightening schedule. It is advisory — you or your attorney file the opposition.

Software for practitioners — not a filing service. TM Watch is the platform your practice runs on: it tracks status, computes statutory deadlines with their basis, watches the Journal and prepares drafts for your review. Every date is advisory — verify against the official Registry record. TM Watch never files, pays, or signs anything with the Registry; you, the attorney, stay in control of every action.

Catch conflicts while you can still oppose.

Scan every weekly Journal against your portfolio and get alerted in time.
