When opposition arises

After an application clears examination, the Registry advertises it in the Trade Marks Journal, published weekly online. Advertisement invites the public to object before the mark is registered. Anyone may oppose: you do not need to own a registered mark, though in practice opponents are usually brand owners who see a similar mark in their field.

For brand owners, the practical lesson is to watch the Journal. Opposing a similar mark at this stage is faster and cheaper than seeking cancellation after registration through rectification, or suing for infringement later.

Grounds of opposition

The grounds are drawn mainly from Sections 9, 11 and 18 of the Act:

• Prior similar mark: the opposed mark is identical or similar to the opponent's earlier mark for similar goods or services, and confusion is likely (Section 11).
• Passing off: use of the opposed mark is liable to be prevented by the law of passing off, which protects even unregistered marks with goodwill (Section 11(3)).
• Well-known mark: the opposed mark would take unfair advantage of, or harm, a well-known mark even for different goods (Section 11(2)).
• Absolute grounds: the mark is descriptive, generic, deceptive or otherwise barred by Section 9.
• Bad faith and false claim of ownership: the applicant is not the true proprietor, for example a former distributor or employee who filed the principal's brand (Section 18).

Stages and time limits

If the applicant fails to file a counter-statement in time, the application is deemed abandoned. If the opponent does not file evidence or inform the Registry that it relies on the notice, the opposition can be treated as abandoned. These consequences are applied strictly, so calendars must be maintained by both sides.

Filing an opposition against someone else's mark

A notice of opposition must set out the opponent's rights, the specific grounds and the relief sought. We first assess whether opposition is worth it: how close the marks are, whether the goods overlap, the strength of your prior use and the cost of proceedings. If you have no registration of your own, we usually advise filing one at once, as an application strengthens your position.

Evidence is the heart of the case. Opponents should collect dated proof of first use, sales across years, advertisements, and any earlier disputes won against similar marks. The evidence is filed by affidavit, and documents must be properly exhibited.

Defending your application against an opposition

A counter-statement must deny the allegations clearly and set out the applicant's own case: the date and extent of use, the honesty of adoption, differences between the marks and the goods, and any weakness in the opponent's claims, such as non-use or a narrow registration. A short or evasive counter-statement weakens the defence at the evidence stage.

Options other than a fight are also considered: narrowing the goods, adding a distinguishing element, or a written coexistence agreement with the opponent. Many oppositions end in settlement, which can then be recorded with the Registry by withdrawal of the opposition.

Hearing, decision and appeal

After evidence closes, the Registrar fixes a hearing, which is now commonly held by video conference. Both sides argue their case, and written submissions are filed. The Registrar may allow the opposition (refusing the application), reject it (letting the mark proceed to registration), or allow registration with conditions or limitations. Costs may be awarded.

An appeal against the Registrar's order lies before the High Court under Section 91 within three months of the order. Since the Tribunals Reforms Act, 2021 abolished the IPAB, these appeals are heard by the High Courts, several of which have dedicated intellectual property divisions.

Fees and how costs build up

The official fee for a notice of opposition and for a counter-statement is charged per class, and is about ₹2,700 per class for e-filing as on date. Professional fees depend on the stage: drafting the notice or counter-statement, preparing evidence affidavits, and attending the hearing. Contested oppositions can run for well over a year, so we quote stage-wise in writing. If an opposition is filed after your application cleared an objection, keep your objection reply and evidence handy, as they are often reused.

Opposition, rectification or a suit: choosing the route

Opposition is only one of three tools against a conflicting mark, and the right choice depends on timing and on what the other side is actually doing.

• Opposition is the right route while the mark is in the four-month window after advertisement. It stops registration before the other side gains statutory rights.
• Rectification is used once the window has passed and the mark is registered, or where the registered mark has not been used for five years.
• An infringement or passing off suit is needed where the other side is already selling goods under the mark. An opposition does not stop use in the market; only a court can do that, by injunction.

These are not exclusive. Where a competitor has both filed an application and started selling, we often oppose the application and send a cease and desist notice at the same time, so that the dispute is resolved on both fronts. A Journal watch service, which reviews each weekly Journal for marks similar to yours, makes sure the opposition window is not missed.

Evidence affidavits deserve real care. They must be sworn by a person with knowledge, usually a director or proprietor, and every document relied on must be exhibited and explained. Unexplained bundles of invoices carry little weight. Where evidence was weak in an earlier proceeding, it cannot simply be repeated; it has to be rebuilt.

Documents you need

The documents depend on which side you are on:

• Journal number, application number and copy of the advertised mark
• Your own trademark registration or application details
• Dated invoices, catalogues and advertisements proving first use
• Sales and promotion figures across years, certified where possible
• The notice of opposition served on you (if defending)
• Signed Form TM-48 authorising us as agent
• Any earlier correspondence, notices or settlements with the other side
