TRADE MARK DILUTION AND WELL-KNOWN MARKS IN INDIA: JUDICIAL OVERREACH

INTRODUCTION

Historically, trade mark law remained satisfactorily linked to a thin consumer protection ground: source identification of goods or service and avoiding public confusion therewith. In the past several decades, the measure of protection extended to certain trade marks has perceptibly shifted its focus from a mere source-indication protection to reputation protection. Where, under the traditional approach to trade mark infringement suits, the prime issue would be whether or not there would be potential consumer confusion over origin, the courts’ gaze is increasingly fixed on whether the junior trade mark detracts from the distinctive feature or reputation of the famous trade mark, i.e., the essence of the dilution doctrine. This shift can also be noticed in the India Trade Marks Act, 1999, where trade marks can be termed ‘well-known marks’ with a corresponding cause of action based upon reputation. However, in their effort to protect these brand values, it seems that cases in this area are going in directions difficult to articulate in terms of legislative intent. The focus of this article is to explore whether the Indian judiciary in its interpretation of cases regarding dilution and well-known marks of trademarks has stepped out of these boundaries.

THE CONCEPT OF TRADE MARK DILUTION AND WELL-KNOWN MARKS

Trade mark Dilution corresponds to the loss of distinctiveness or reputation resulting from unauthorised use, even in the absence of confusion. It differs from the infringement mark as it instead prevents the loss of the mark’s selling power as opposed to source identification. There are two main types of dilution that typically occur. These are blurring and tarnishment. Blurring occurs as a mark becomes less distinct as it is used in conjunction with unrelated products. Tarnishment is the mark’s reputation being damaged by something that is deemed to be disreputable. Famous trademarks constitute the intellectual basis of the scope of dilution protection. These trademarks receive superior protection on account of their recognition not being limited to a particular product but being entrenched in the consciousness of the public. The underlying reason is the prevention of free riding on such trademarks and their accrued market magnetism. Nonetheless, the superior status of these trademarks constitutes a shift from the principle of territory, thereby exhibiting potential tendencies towards monopolisation of space.

The underlying theory justifying the protection of well-known trademarks against dilution is the belief that some trademarks attain an autonomous economic value that stands apart from the goods and services that the trademarks represent. These trademarks do not merely indicate the origin of the goods but also embody the accumulated trust, lifestyle, and meaning of the consumers. The unauthorized use of trademarks in non-comparative situations may enable the junior party to tap into such accumulated trust without shouldering the investment costs. Hence, the basis of dilution protection lies in shielding the trademark from losing its communicative and associational strength in the marketplace.

On the other hand, however, the recognition of trade marks as quasi-property rights on the basis of reputation triggers several normative questions. In particular, if dilution protection is granted broadly, it may lead to recognition of brand recognition analogously to a right of perpetual exclusivity that exceeds the proper scope of trade mark protection. Over-expansive protection of well-known marks may stifle fair competition by reducing the functionality of generic words, symbols, or cultural references. It is with this in mind that a balanced approach in dilution is called for in dilution jurisprudence—a balance that acknowledges the special status of “famous” marks while preventing their protection from petrifying into an “unwarranted monopoly” over “market language”.

STATUTORY FRAMEWORK UNDER THE TRADE MARKS ACT, 1999

Dilution and well-known mark protection are brought about by the Trade Marks Act, 1999, mainly by Sections 11 and 29(4). The well-known mark is defined by Section 2(1) (zg) as a mark which is known to a substantial part of the public as to signify an association with the proprietor when used on other goods. The criterion to distinguish well-known marks is provided by Sections 11(6) and 11(7), and it includes recognition, period of use, advertising, and enforcement. Sections 11(9) states that in India, there is no necessity to register or use the mark, while Section 11(10) states the necessity to provide protection against conflicting marks.

Under section 29(4), the cause of action for dilution can be restrained against use on dissimilar goods if the registered mark has a reputation in India and if such use takes unfair advantage of and depreciates the distinguishing character or reputation of the mark. The requirement of the section appears to be narrowly focused and of an evidentiary nature. However, judicial interpretation has often expanded this scope by presuming reputation and harm.

 JUDICIAL EVOLUTION OF DILUTION JURISPRUDENCE IN INDIA

The Indian judiciary’s attitude towards dilution started cautiously. The earlier cases began with the concepts of goodwill, prior usage, and reputation. The judgment remained grounded in the principles of consumer protection. The recognition of the ‘trans-border reputation’ by the Supreme Court brought a major shift. The brand could be protected even if it’s not registered in the country. Over the years, courts started realizing the concept of dilution as a separate harm. Case laws like Daimler Benz v. Hybo Hindustan and Tata Sons v. Manoj Dodia indicated a departure towards robust reputation protection, including for unconnected products. These judgments established the premise for liberal judicial construction of dilution.

Starting from 2022, there is more evident extension of the principles. It is more common for courts to hold a mark to be well-known and grant injunction relief with less scrutiny regarding actual harm. Digital commerce has further fueled such developments, with courts being more willing to enjoin domain names, marketplace listings, and cyberspatial uses of famous marks. In a couple of decisions from 2023 to 2025, high damages awards have been available with liability against intermediaries, with a pro-brand attitude being promoted. Although these rules are aimed at preventing misappropriation, they considerably depend on the reputation of the mark instead of substantial evidence of the negative impact. This results in the idea of dilution being presumed simply based on reputation instead of being the exception.

A notable consequence of this judicial trajectory is the gradual dilution of the statutory safeguards embedded in Section 29(4) of the Trade Marks Act, 1999. Courts have, in several recent cases, treated the existence of reputation as sufficient to infer both unfair advantage and detriment, effectively collapsing the multi-pronged statutory test into a single inquiry centred on fame. This approach departs from the legislative design, which envisages dilution as an exceptional cause of action requiring affirmative proof that the defendant’s use exploits or harms the distinctive character of the mark. By presuming harm rather than demanding evidence of economic or reputational injury, courts risk transforming dilution into a strict-liability doctrine for well-known marks. One of the most significant effects resulting from this judicial pathway is the weakening of the protective provision enshrined within Section 29(4) of the Trade Marks Act, 1999. It has been observed in various judgments passed by the courts in recent years that the presence of reputation is enough to conclude both unfair advantage and detriment, in effect merging the multi-fact requirement within the statutory provision into a single dimension focused on fame. However, this judicial stance goes against the intention of the legislation that provides dilution as an extraordinary action requiring judicial ascertainment in affirmatively established cases where the defendant’s act is known to exploit and/or damage the distinctive feature of the mark.

This expansion further gives rise to wider constitutional and policy questions. The liberal protection of dilution could cause a disproportionately high limit on Freedom of Trade under Article 19(1)(g) of the Indian Constitution, especially when injunctive relief is granted for non-competitive and descriptive use. The lack of a nuanced examination of proportionality only adds fuel to fire in an already tricky balancing act, as it is highly unlikely for courts to limit a defendant’s right to conduct business on a balancing scale with the de minimis damages alleged by a holder of a famous mark. The comparative experience clearly establishes that a balanced treatment of dilution and market competition is possible only when courts adhere to a requirement of harm and a healthy dose of judicial sobriety.

JUDICIAL OVERREACH AND ITS CONSEQUENCES

The broader scope of the dilution doctrine raises the issue of judicial overreach as the liberalized standards of evidence are likely to cause the dilution doctrine to be applied in the manner of strict liability with respect to famous trademarks. Too much protection can be given to famous trade marks. This can negatively impact the level of competition. Start-ups or small businesses are afraid of being sued and hence are discouraged from engaging in genuine trade mark practices. Common language and symbols are essentially monopolized. This results in low market entry and innovation. This is considered trade mark bullying and disrupts the equilibrium that trade mark law aims to achieve. In addition, there is a tension between the structure of brand law and competition law. Too much brand law can operate as a non-tariff barrier to competition. Indeed, when courts place more weighting on reputation than competition, there is a risk that economic liberty is subordinated to private monopoly.

This judicial bias in favor of broad dilution protection also raises important concerns about institutional competence and the separation of powers. In so far as judges begin to weigh in with their interpretation of brand protection cum market freedom, there may be concerns about judges overstepping their institutional mandate in traversing this delicate balance. Starting from a democratically defined definition under legislation under the Trade Marks Act of 1999, judges also run the risk of usurping a legislative mandate in crafting near absolute rights to well-known brand trademarks in situations where Parliament has not indicated any legislative guidance in this regard.

COMPARATIVE JURISPRUDENCE

Comparative jurisprudence is also highly instructive. In United States law, for a mark to be protected under dilution, it must be famous, and a likelihood of dilution must be proved. In European cases, a concrete link must also be established between the marks, and a demonstrated effect on distinctive character or repute. These countries consider dilution to be an extraordinary remedy rather than an automatic effect of fame. In contrast to India’s “dilution” jurisprudence that appears to treat reputation-based protection more flexibly – without adequate consideration for proportionality, it is suggested that a more disciplined standard of evidence is required to safeguard famous marks while not unduly hampering competition.

CONSTITUTIONAL AND POLICY DIMENSIONS

Broad dilution protection raises constitutional concerns under Article 19(1)(g) of the Indian Constitution, which guarantees freedom of trade. Injunctions granted without proportional justification may amount to unreasonable restrictions not saved under Article 19(6). There is also a separation-of-powers concern when judicial interpretation effectively rewrites statutory standards. From the point of view of policy, trade mark law has to strike a balance between incentive and access: protection of investment in brands is legitimate but it should not be at the expense of market diversity and entrepreneurial freedom.

SUGGESTION

There is a need for a reinterpretation of the dilution case law tradition under Indian law. The courts must require evidence of unfair advantage/detriment to be shown, and a presumption of dilution on the basis of fame alone must be avoided. If the Registrar’s system of making a formal ‘well-known mark’ decision was given a bigger role, this could increase transparency and predictability. Application of the principles of competition and proportionality assessment could improve the consistency of the case law.

CONCLUSION

Trade mark dilution has a crucial role in ensuring that only those marks which are truly famous are given protection with regard to reputation. Uncontrolled usage of trade mark dilution has a very harmful effect, as it confers monopolies. Indian courts must see to it that trade mark dilution becomes a rarity that has any support in law. Only then can any law on trade marks remain a good servant of both public and private initiatives.
