Topic 33 — Relative Grounds for Refusal of Registration and Honest Concurrent Use
While Section 9 of the Trade Marks Act 1999 looks inward — at the qualities of the mark itself — Section 11 looks outward, at the rights of third parties. The "relative grounds" for refusal apply where registration of a mark would conflict with another's prior trademark or with another's common-law rights. Section 11 is therefore the gatekeeper that prevents the Register from filling up with confusingly similar marks. Section 12 supplies the safety valve — honest concurrent use, which permits the Registrar to register multiple identical or similar marks where two parties have independently and in good faith used the same mark. This topic walks through Section 11 in detail, the deceptive-similarity test from Cadila Health Care v. Cadila Pharmaceuticals (2001), the well-known mark protection under Section 11(6)-(10), and Section 12 honest concurrent use.
1. The Architecture of Section 11
Section 11 has five operative parts:
Sub-section | Subject |
|---|---|
Section 11(1) | Likelihood of confusion with prior mark (similar mark + similar goods). |
Section 11(2) | Use detrimental to or taking advantage of an earlier well-known mark (cross-class). |
Section 11(3) | Use prevented under any law (e.g., passing off, copyright). |
Section 11(4) | Saving — does not prevent registration with consent of the earlier rights-holder. |
Section 11(5) | Application of grounds raised by the Registrar suo motu vs. on opposition. |
Section 11(6)–(10) | Well-known marks framework (covered in detail in Topic 31). |
2. Section 11(1) — Confusion with Prior Marks
Section 11(1) — Likelihood of Confusion "Save as provided in section 12, a trade mark shall not be registered if, because of — (a) its identity with an earlier trade mark and similarity of goods or services covered by the trade mark; or (b) its similarity to an earlier trade mark and the identity or similarity of the goods or services covered by the trade mark, there exists a likelihood of confusion on the part of the public, which includes the likelihood of association with the earlier trade mark." |
A. The Two-Pronged Test
Section 11(1) sets up a two-pronged test:
- Identity or similarity of marks — the impugned mark must be either identical with or similar to the earlier mark.
- Identity or similarity of goods or services — the goods or services must be either identical with or similar to those of the earlier mark.
Both prongs must be satisfied. If the marks are identical and the goods are identical, refusal is automatic. If only one prong is met (say, identical marks but unrelated goods), Section 11(1) does not apply — though Section 11(2) on dilution may step in for famous marks.
✅ "Earlier trade mark" defined Section 11(1) refers to an "earlier trade mark". Section 11(4) Explanation defines this as (i) a registered trademark with an earlier filing or priority date, (ii) a Convention application with an earlier priority date, and (iii) a trademark that, on the date of application, was entitled to protection as a well-known trademark. Even an unregistered well-known mark therefore counts as an "earlier trade mark" for Section 11(1) purposes. |
3. The Deceptive Similarity Test — Cadila Health Care
📖 Cadila Health Care Ltd. v. Cadila Pharmaceuticals Ltd., (2001) 5 SCC 73 Facts — Cadila Health Care marketed a brand "FALCITAB" for malaria treatment. Cadila Pharmaceuticals (a different company) marketed "FALCIGO" for the same condition. Cadila Health Care sued for passing off; pharmaceutical-mark confusion. Holding — The Supreme Court (Justice B.N. Kirpal) held that confusion in pharmaceutical marks demands a stricter standard than in ordinary goods, given the public-health stakes. The Court laid down a multi-factor test for deceptive similarity: (i) The nature of the marks (word/composite; visually similar/dissimilar). (ii) The degree of resemblance — phonetic, visual, conceptual. (iii) The nature of the goods (whether for the same purpose or different). (iv) The class of customers (educated/uneducated; specialist/general). (v) The purchaser's level of intelligence and degree of care. (vi) The mode of purchase (over the counter, prescription, online). (vii) Surrounding circumstances and the likelihood of confusion. Significance — The locus classicus on deceptive similarity in Indian trademark law. The factors are applied in every infringement and opposition case where similarity is in dispute. |
A. Three Dimensions of Similarity
Indian courts assess similarity along three dimensions:
1 PHONETIC how it sounds | 2 VISUAL how it looks | 3 CONCEPTUAL what it suggests |
- Phonetic similarity — how the marks sound when pronounced. Examples of phonetic confusion: "PIDILITE" vs "PIDIVITE"; "AMUL" vs "AMRUT"; "MOTILAL" vs "MOTILALA"."
- Visual similarity — how the marks look when written or rendered. Includes typeface, layout, colour, device elements. Examples: stylised script that mimics another's logo; nearly-identical layouts of word marks.
- Conceptual similarity — what the marks evoke or signify in the consumer's mind. Examples: "MERCURY" and "QUICKSILVER" both signify speed; "LION" and "TIGER" both signify strength.
B. The "Average Consumer" Standard
Confusion is judged from the perspective of the "average consumer" of the goods or services in question — not the trademark expert, not the careful comparative shopper. The Indian courts (following the Cadila factors) have treated the average consumer as someone who relies on imperfect recollection, encounters the marks at different times in different settings, and pays varying levels of attention depending on the goods.
✅ Pharmaceuticals get extra scrutiny Cadila Health Care held that pharmaceutical marks must be assessed by a stricter standard than ordinary consumer goods. Confusion in medicines can mean wrong drugs, allergic reactions, even death. The Court held that "even a remote possibility of confusion" should weigh against registration in pharmaceutical cases. This stricter standard has been consistently applied in subsequent pharmaceutical-mark cases. |
4. Section 11(2) — Dilution of Well-Known Marks
Section 11(2) — Dilution "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 which are not similar to those for which the earlier trade mark is registered in the name of a different proprietor, shall not be registered if or to the extent the earlier trade mark is a well-known trade mark in India and the 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 trade mark." |
Section 11(2) implements the cross-class protection of well-known marks. Where the goods are dissimilar but the earlier mark is well-known, registration is barred if the later use would dilute the earlier mark's distinctiveness or take unfair advantage of its reputation. The provision works in tandem with Section 29(4) (infringement by dilution) and Section 11(6)-(10) (well-known mark factors). The Haldiram and Boroline 2024 decisions (Topic 31) apply this framework.
5. Section 11(3) — Other Legal Bars
Section 11(3) — Other Legal Bars "A trade 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 law of copyright." |
Section 11(3) is the catch-all relative-ground provision. It bars registration if the mark's use would be prevented by:
- Passing off — common-law protection of an unregistered trademark with goodwill (the classic Reckitt & Colman trinity).
- Copyright — where the mark incorporates a copyrighted work (e.g., a logo containing a copyrighted artistic work; a sound mark containing a copyrighted musical phrase).
✅ Section 11(3)(a) — passing off as a registration ground Section 11(3)(a) is significant because it gives common-law trademark rights formal weight in registration proceedings. A senior unregistered user, with established goodwill, can oppose registration of a similar mark by a junior applicant. The Yahoo! Inc. v. Akash Arora (1999) decision on domain names extended this principle into the cybersquatting context. |
6. Section 11(4) — Consent and Letter of Consent
Section 11(4) "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..." |
Section 11(4) carves out an exception: where the proprietor of the earlier mark gives written consent (a "Letter of Consent"), registration is permitted despite the relative-ground objection. This is widely used in:
- Group company registrations — where one group entity gives consent to another to register a similar mark.
- Coexistence agreements — where two unrelated parties agree to coexist with delimited use of similar marks.
- Business reorganisations — where mark portfolios are split between successor entities.
7. Honest Concurrent Use — Section 12
Section 12 — Registration in Case of Honest Concurrent Use "In the case of honest concurrent use or of other special circumstances which in the opinion of the Registrar, make it proper so to do, he may permit the registration by more than one proprietor of the trade marks which are identical or similar (whether any such trade mark is already registered or not) in respect of the same or similar goods or services, subject to such conditions and limitations, if any, as the Registrar may think fit to impose." |
Section 12 supplies the safety valve. Where two parties have independently and in good faith used identical or similar marks for similar goods, the Registrar can register both, subject to conditions:
- Geographic limits — Party A in North India, Party B in South India.
- Trade-channel limits — Party A in retail, Party B in wholesale.
- Format limits — Party A in word form, Party B in stylised form.
- Class limits — restrict each registration to specific goods within the broader class.
Five Factors for Honest Concurrent Use
Indian courts (following the UK case Pirie's Application, [1933] 50 RPC 147) consider five factors:
- Honesty of concurrent use — both parties must have adopted the mark in good faith, without knowledge of the other.
- Length of use — substantial period of concurrent use.
- Volume and locality of trade — extent of each party's commercial activity.
- Likelihood of confusion — actual evidence of confusion or its absence.
- Acquiescence — whether either party has known of the other and acquiesced.
📖 Pirie's Application, [1933] 50 RPC 147 (UK) The classical UK statement of the honest-concurrent-use doctrine. Adopted by Indian courts in numerous decisions; the five Pirie factors form the operational test for Section 12 applications. |
8. Special Doctrines under Section 11
A. Doctrine of Imperfect Recollection
Indian courts assume that consumers do not have the marks side-by-side for comparison; they encounter them at different times. The "imperfect recollection" of the average consumer means that small differences may not register, and similarities are amplified. This doctrine, well-established in trademark law, raises the bar for marks claiming visual or phonetic distance from earlier marks.
B. Doctrine of Initial Interest Confusion
Even if confusion is dispelled at the time of purchase, infringement can be made out if there was confusion at an earlier "interest" stage — for example, when a consumer searches online and reaches the wrong website. Indian courts have applied this doctrine in domain-name disputes (Yahoo! v. Akash Arora 1999) and search-engine-keyword cases.
C. Doctrine of Reverse Confusion
Confusion arises not only when the junior user benefits from the senior user's goodwill, but also when a junior user with deeper pockets so saturates the market that consumers come to associate the senior user's goods with the junior user. The senior user is, in effect, "buried" by the junior. Indian courts have not formally adopted reverse confusion as a separate doctrine, but the principle has been applied in some cases.
D. Doctrine of Family of Marks
A trademark proprietor with a series of marks sharing a common element (e.g., McDonald's "Mc-" prefix series — McChicken, McNuggets, McSpicy, McAloo) is entitled to protect the common element across the family. A junior applicant using the same prefix may be refused even if no individual prior mark is identical.
9. Practical Implications for Trademark Practice
✅ Eight points for trademark practitioners on relative grounds Conduct a comprehensive search before filing — Trade Marks Registry, Indian common law (passing off), and well-known marks list. For dual-class applications, consider whether Section 11(2) dilution may apply against well-known marks in unrelated classes. Apply the Cadila multi-factor test in opposition pleadings — phonetic, visual, conceptual; nature of goods; class of customers; mode of purchase; surrounding circumstances. For pharmaceutical marks, plead the stricter Cadila standard — even remote possibility of confusion supports refusal. For Section 11(4) applications, secure a clean Letter of Consent — specifying the marks, classes and any limitations. For Section 12 honest concurrent use, gather Pirie-factor evidence — particularly the independence and good faith of adoption. For passing-off-based oppositions under Section 11(3)(a), establish the trinity: goodwill + misrepresentation + damage. Keep written records of mark-clearance investigations as evidence of good faith for any future disputes. |
