Key Point: A “well-known trademark” in India enjoys cross-class protection — protection across all 45 trademark classes, including industries completely unrelated to the mark’s original business. This is the highest level of trademark protection available under Indian law, defined under Section 2(1)(zg) of the Trade Marks Act 1999.
Official Well-Known Marks List: CGPDTM maintains a public list of trademarks declared well-known in India. You can view it and submit applications at the IP India — CGPDTM official portal (ipindia.gov.in) under Trademark → Well-Known Trademarks.
Most brand owners think of trademark protection in terms of their specific products or services. A food company registers its mark in Class 30; a software firm registers in Class 42. But what if your brand becomes so famous that even using a similar name on completely unrelated products would cause confusion or take unfair advantage of your reputation?
That is precisely what well-known trademark status protects against. It is the legal recognition that your brand has transcended its original industry and deserves protection everywhere. This guide explains the criteria, the benefits, the application process, and what Indian brands have already achieved this status.
What Is a Well-Known Trademark? (Section 2(1)(zg))
Under Section 2(1)(zg) of the Trade Marks Act 1999, a well-known trademark is defined as a mark that has become so well known to a substantial segment of the public which uses such goods or services, that the use of such mark in relation to other goods or services would be likely to be taken as indicating a connection between those other goods or services and the person using the mark.
In simpler terms: a brand is “well-known” when a significant portion of its target consumers are so familiar with it that seeing the same name or logo on something else — a different product, a different industry — would make them think it is somehow connected to the original brand owner.
The Trade Marks Registry maintains an official list of marks declared well-known. Once on this list, the mark receives statutory well-known status — a stronger and more predictable form of protection than just being famous in practice.
Key Benefits of Well-Known Trademark Status
Cross-Class Protection
Your mark is protected across all 45 trademark classes, not just the ones you registered in. No one in any industry can register a confusingly similar mark.
Blocks Similar Marks at Filing
The Registry must refuse any new application for an identical or similar mark in any class — even if your mark is not registered in that class — under Section 11(2).
Anti-Dilution Protection
Even without confusion, use that tarnishes or blurs your mark’s distinctive character or reputation is actionable under Section 29(4).
Stronger Enforcement
Well-known status makes trademark infringement and passing off cases significantly easier to win. Courts give greater weight to these marks in disputes.
Higher Brand Valuation
Official recognition of well-known status increases the brand’s value for licensing, franchising, investment, and M&A transactions.
Domain Name Disputes
Well-known status strengthens your position in domain name disputes under INDRP (India’s domain dispute resolution policy) and UDRP proceedings globally.
Standard Registered Mark vs. Well-Known Mark: Comparison
| Feature | Standard Registered Mark | Well-Known Mark |
|---|---|---|
| Protection scope | Limited to registered class(es) only | All 45 classes (cross-class) |
| Confusion required for infringement | Yes (for similar goods/services) | No — even non-competing use on unrelated goods can infringe |
| Blocking power at Registry | Blocks only in same/similar class | Blocks in all classes |
| Anti-dilution protection | Limited | Full dilution protection under Section 29(4) |
| Fame required to prove | No | Yes — must demonstrate widespread recognition |
| Listed on official CGPDTM register | No separate listing | Yes — public CGPDTM well-known marks list |
| Application/petition required | Standard Form TM-A | Form TM-M (Rule 124) plus extensive evidence |
Criteria for Well-Known Status (Section 11(6)–(9))
The Registry considers the following factors when determining whether a trademark qualifies as well-known:
Knowledge and Recognition Among Relevant Public
The degree to which the mark is known among the relevant section of the public — including knowledge acquired through promotion or advertising.
Duration and Extent of Use
The duration and geographical extent of use of the trademark, and the scale of business associated with it.
Duration and Extent of Promotion
How long and how widely the mark has been advertised and promoted, including at trade fairs, exhibitions, or through media campaigns.
Record of Successful Enforcement
The successful outcome of proceedings that recognised the well-known character of the mark — court judgments, Registry decisions, or opposition victories.
Value Associated with the Mark
The value associated with the trademark in relation to the goods or services — brand valuations, licensing income, royalties, or franchise revenues.
Important: Under Section 11(9), a trademark need not be registered in India, used in India, or applied for registration in India to be recognised as well-known in India. A globally famous mark can be declared well-known in India even if the owner has never conducted business in India — based on international reputation alone. This is a significant protection for global brands entering the Indian market.
How to Apply for Well-Known Trademark Status in India
- File Form TM-M (Rule 124) — The application for determination of a trademark as well-known is filed using Form TM-M with CGPDTM under Rule 124 of the Trade Marks Rules 2017. The government fee is ₹1,00,000 (one lakh rupees) — reflecting the premium nature of this status. The application can be filed online through the IP India portal.
- Prepare Comprehensive Evidence — The strength of your application depends on the evidence you submit. Include: sales turnover figures by year, advertising spend over multiple years, media coverage (newspaper, magazine, TV, online), market research surveys showing consumer recognition, number of countries where the mark is registered, court decisions recognising the mark’s fame, and any existing brand valuation reports.
- Submit Trademark Registration Details — Provide details of all trademark registrations in India and abroad — including application numbers, registration numbers, classes, and dates. If the mark is registered internationally under the Madrid Protocol, include the international registration certificate. Guide: How to Register a Trademark in India.
- Registry Examination and Decision — CGPDTM examines the application and evidence. The Registrar may call for additional information or a hearing. If satisfied, the Registrar issues an order declaring the trademark as well-known and adds it to the official list published on the IP India website.
Examples of Well-Known Trademarks in India
CGPDTM’s published well-known marks list includes both Indian brands and global brands recognised in India. Some notable examples:
- BAJAJ
- BATA
- BISLERI
- DR. REDDY
- ENFIELD BULLET
- GILLETTE
- CARTIER
- CATERPILLAR
The Registry's list had about 275 marks as of early 2025.
Note: The official CGPDTM well-known marks list is regularly updated. The brands above are taken from the Registry's published list. For the current official list, visit the IP India portal directly. Indian brands that have achieved this status demonstrate that well-known status is accessible to domestic companies — not just global multinationals — with the right evidence and a sustained brand-building track record.
Well-Known Status and Trademark Infringement
Well-known status dramatically strengthens infringement claims. Under Section 29(4) of the Trade Marks Act, the owner of a well-known mark can sue for infringement even if:
- The infringer is operating in a completely different industry
- There is no direct competition between the two brands
- Consumers are not actually confused — but the infringer is taking unfair advantage of the mark’s reputation (free-riding) or causing detriment to the mark’s character
This makes well-known status a powerful deterrent against brand dilution. For the full picture on infringement remedies: Trademark Infringement in India — How to Protect Your Brand.

Frequently Asked Questions
Does my trademark need to be registered in India before applying for well-known status?
No. Section 11(9) explicitly states that a trademark need not be registered in India, or even used in India, to qualify for well-known status. Global fame and recognition in India (through media, imports, or consumer awareness) is sufficient. However, having Indian registrations strengthens the application considerably and makes enforcement easier.
Can a well-known trademark status be challenged or revoked?
Yes. Any person can file a petition to challenge or revoke well-known status if they believe the determination was made incorrectly — for example, if the evidence submitted was fraudulent or the mark no longer qualifies. The burden of proving that the mark qualifies (or no longer qualifies) shifts depending on which party makes the challenge. Courts and the Registry can also review well-known determinations in the context of litigation.
How long does the well-known trademark application process take?
There is no fixed statutory timeline for the Registry’s decision on a well-known trademark application. Applications backed by comprehensive, well-organised evidence tend to move faster.
Can a court declare a trademark well-known even without a Registry application?
Yes. Courts in India (particularly High Courts) have the power to declare a trademark well-known in the context of infringement or passing off litigation, even without a formal Registry application under Rule 124. Many famous trademarks attained judicial recognition of their well-known status through court proceedings before the formal administrative route was established. Both routes are valid.
What is the difference between a “well-known” trademark and a “famous” trademark?
In Indian law, the term is specifically “well-known trademark” as defined under Section 2(1)(zg). There is no separate legal category called “famous trademark” in Indian trademark law. The term “famous mark” is used in US trademark law (under the Lanham Act) and offers similar dilution protection in that jurisdiction. When Indian IP professionals refer to “famous marks,” they usually mean marks that meet the criteria for well-known status even if the formal declaration has not yet been obtained.
Where can I see the list of well-known trademarks?
The list is published on the IP India website and updated when new marks are added.
