Section 11 explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
Where section 9 looks at the mark by itself, section 11 looks at it against other people's rights: earlier marks, well-known marks, passing off and copyright. It is the section behind most "cited mark" objections. This article reads all eleven sub-sections plus the Explanation; for the reply side see our guides on cited prior marks under section 11 and well-known marks under section 11.
Save as provided in section 12, a mark shall not be registered if, because of identity or similarity with an earlier trade mark and identity or similarity of goods or services, there is a likelihood of confusion on the part of the public, including likelihood of association (11(1)). A well-known earlier mark is protected even against dissimilar goods where use would take unfair advantage or be detrimental (11(2)). Prior passing off and copyright rights also bar registration (11(3)). The earlier proprietor's consent can open the door (11(4)).
Section 11(1): likelihood of confusion
"Save as provided in Section 12", a trade mark shall not be registered if there exists a likelihood of confusion on the part of the public, which includes the likelihood of association with the earlier trade mark, because of:
| Limb | Marks | Goods or services |
|---|---|---|
| (a) | Identity with an earlier trade mark | Similarity of goods or services covered |
| (b) | Similarity to an earlier trade mark | Identity or similarity of goods or services |
So the sub-section needs two things together: a closeness between the marks and a closeness between the goods or services. Identical marks on dissimilar goods do not fall in 11(1); they are dealt with, for well-known marks, in 11(2). The opening words "save as provided in Section 12" point to honest concurrent use. The "deceptively similar" test in 2(1)(h) is the related definition; see section 2, part 3. If an examination report cites an earlier mark against you under this sub-section, our trademark objection reply service handles the response.
Section 11(2): well-known earlier marks and dissimilar goods
A trade mark which (a) is identical with or similar to an earlier trade mark, and (b) is to be registered for goods or services not similar to those for which the earlier mark is registered in the name of a different proprietor, shall not be registered if or to the extent the earlier mark is a well-known trade mark in India and use of the later mark without due cause would take unfair advantage of or be detrimental to the distinctive character or repute of the earlier mark.
Four conditions run together: similarity of marks, dissimilar goods, the earlier mark being well known in India, and unfair advantage or detriment without due cause.
Section 11(3): passing off and copyright
A mark shall not be registered if, or to the extent that, its use in India is liable to be prevented:
- (a) by virtue of any law, in particular the law of passing off protecting an unregistered trade mark used in the course of trade; or
- (b) by virtue of the law of copyright.
This is how an unregistered mark or a copyright work can stand in the way of a later registration. See passing off.
Section 11(4): consent of the earlier proprietor
"Nothing in this section shall prevent the registration of a trade mark where the proprietor of the earlier trade mark or other earlier right consents to the registration, and in such case the Registrar may register the mark under special circumstances under Section 12." A template is at NOC from a prior trademark owner. The text says "may register", so acceptance is for the Registrar.
The Explanation: what is an "earlier trade mark"
For the purposes of section 11, "earlier trade mark" means:
| Limb | Text |
|---|---|
| (a) | A registered trade mark, or an application under Section 18 bearing an earlier date of filing, or an international registration referred to in Section 36E, or a convention application referred to in Section 154, which has a date of application earlier than the mark in question, taking account of any priority claimed |
| (b) | A trade mark which, on the date of application (or priority date), was entitled to protection as a well-known trade mark |
A footnote records that limb (a) was substituted by Act 40 of 2010 with effect from 8 July 2013. So an earlier pending application and an international registration can count, not only a registered mark.
Section 11(5): when 11(2) and 11(3) can be raised
A trade mark shall not be refused registration on the grounds in sub-sections (2) and (3) unless objection on one or more of those grounds is raised in opposition proceedings by the proprietor of the earlier trade mark. So the Registrar will not refuse on well-known-mark or passing-off or copyright grounds on his own; the earlier proprietor must raise it in opposition. Section 11(1) is not covered by this restriction. For opposition itself, see opposition.
Section 11(6): factors for a well-known mark
The Registrar, in deciding whether a mark is well known, shall take into account any fact he considers relevant, including:
- knowledge or recognition in the relevant section of the public, including knowledge in India obtained through promotion;
- duration, extent and geographical area of use;
- duration, extent and geographical area of promotion, including advertising and presentation at fairs or exhibitions;
- duration and area of any registration or application, to the extent they reflect use or recognition;
- the record of successful enforcement, including recognition as well known by any court or Registrar.
Section 11(7): relevant section of the public
For 11(6), the Registrar shall take into account (i) the number of actual or potential consumers; (ii) the number of persons in the channels of distribution; and (iii) the business circles dealing with the goods or services.
Section 11(8): earlier recognition
Where a mark has been determined well known in at least one relevant section of the public in India by any court or Registrar, the Registrar shall consider it a well-known trade mark for registration under the Act.
Section 11(9): what the Registrar cannot demand
The Registrar shall not require, as a condition for finding a mark well known, that:
- the mark has been used in India;
- it has been registered;
- an application for registration has been filed in India;
- it is well known, registered or applied for in any jurisdiction other than India; or
- it is well known to the public at large in India.
Section 11(10): protection and bad faith
When considering an application and any opposition, the Registrar shall (i) protect a well-known trade mark against identical or similar marks and (ii) take into consideration bad faith of the applicant or the opponent affecting the right to the mark.
Section 11(11): good-faith saving
Where a mark has been registered in good faith disclosing material information to the Registrar, or a right to a mark has been acquired through use in good faith before the commencement of this Act, nothing in the Act shall prejudice the validity of the registration or the right to use the mark on the ground that it is identical with or similar to a well-known trade mark.
Example. "Zenara" is registered for sarees. A trader applying for "Zenara" for sarees (identical marks, identical goods) meets 11(1)(a). One applying for "Zenara" for cement is not caught by 11(2) unless "Zenara" is well known in India and the use would take unfair advantage or be detrimental; and under 11(5) the sarees proprietor must raise it in opposition.
Need help with a Section 11 objection?
A citation under section 11 means the examiner sees a clash with an earlier mark. The reply usually turns on how close the marks and goods are, and sometimes on consent or evidence of use. Our trademark objection reply team prepares the response and appears at the hearing.
Key takeaways
- 11(1) needs closeness of marks and of goods or services, with likelihood of confusion including association.
- 11(2) protects well-known earlier marks against dissimilar goods.
- 11(3) bars marks whose use is liable to be prevented by passing off or copyright.
- 11(4): the earlier proprietor's consent can open registration, with the Registrar using section 12.
- 11(5): grounds in 11(2) and (3) must be raised in opposition.
- The Explanation counts pending applications, international registrations and convention applications as "earlier".
