How to Oppose (or Defend) a Trademark Application in India: The Form TM-O Process

When Opposition Becomes Available — Journal Publication

Before a trademark application matures to registration, it is published in the Trade Marks Journal, giving third parties an opportunity to object before the mark is actually registered. This publication step exists precisely so that a brand owner who believes a newly applied-for mark conflicts with their own rights does not have to wait until after registration, and then pursue the more difficult route of a rectification or cancellation action, to raise that objection — opposition at the journal-publication stage is the earlier, generally more efficient point of intervention.

The Four-Month Window to File Form TM-O

Under Section 21 of the Trade Marks Act, 1999, a notice of opposition must be filed on Form TM-O within four months of the mark's publication (or re-publication, where applicable) in the Trade Marks Journal. This period is treated strictly by the Trade Marks Registry, and Rule 44 of the Trade Marks Rules allows only a limited extension on a showing of sufficient cause — brand owners monitoring for potentially conflicting marks should not assume a lenient or open-ended grace period exists, and should treat the four-month window as a hard deadline to calendar the moment a conflicting mark is spotted in the Journal.

Filing itself is done electronically through the Trade Marks Registry's e-filing system, with the current e-filing fee payable per class in which opposition is sought (a lower fee applies to e-filing than to physical filing, consistent with the Registry's broader push toward electronic processing) — the exact fee should always be checked against the Trade Marks Rules' current fee schedule at the time of filing, since these fees are revised from time to time.

What a Notice of Opposition Should Contain

A notice of opposition needs to set out the specific grounds on which registration is opposed, with sufficient particulars for the applicant to understand and respond to the case being made — a bare assertion that the applied-for mark is objectionable, without specifying why, invites early difficulty. The most commonly invoked grounds include deceptive similarity to, or likelihood of confusion with, an earlier registered or well-known mark; that the mark is descriptive of the goods or services, or otherwise lacks the distinctiveness required for registration; that the application was made in bad faith; and prior use of an identical or similar mark by the opponent predating the applicant's claimed date of first use. Opponents relying on prior use, rather than a prior registration, should be prepared to substantiate that use with genuine documentary evidence at the evidence stage, since a bare assertion of "prior use" carries little weight without it.

The Applicant's Response: The Counter-Statement Stage

Once the notice of opposition is served on the applicant, the applicant must file a counter-statement responding to the grounds raised within the statutory window measured from receipt of the notice. Failure to file a counter-statement within that window has a serious consequence: the application is treated as abandoned, and the opposed mark does not proceed to registration. Applicants who receive a notice of opposition should therefore treat the counter-statement deadline as time-critical from the outset, engaging counsel promptly rather than waiting to assess the opposition's merits before calendaring the response — a substantively weak opposition still succeeds by default if the applicant simply misses the counter-statement deadline.

Evidence Exchange

Once the counter-statement is on record, the matter moves into a structured evidence stage: the opponent first files evidence in support of the opposition, typically by way of affidavit exhibiting the documents relied on (registration certificates, evidence of prior use, evidence of reputation or well-known status, and similar material); the applicant then files evidence in support of the application, responding to the opponent's case and substantiating the applicant's own claimed rights and use; and a further, narrower window is available for the opponent to file evidence strictly in reply to points raised in the applicant's evidence, rather than to reargue the opposition afresh. Each stage carries its own statutory time limit from the Trade Marks Rules, which parties should confirm at the time of filing, since delay at any stage risks the evidence being taken as not filed.

Hearing and Appeal

After the evidence stage closes, the Registry lists the opposition for a hearing, at which both sides present their case before a hearing officer who then decides whether the opposition succeeds, in whole or in part, or whether the application should proceed to registration. A party aggrieved by the Registry's decision can appeal — since the Intellectual Property Appellate Board was abolished under the Tribunals Reforms Act, 2021, that appellate jurisdiction over trademark opposition and other trademark matters now lies with the relevant High Court, and parties should confirm the current appellate procedure and any recent High Court practice directions applicable to trademark appeals in their jurisdiction before filing.
