When Does Comparative Advertising Become Trademark Infringement in India?

When Does Comparative Advertising Become Trademark Infringement in India?. Comparative advertising is an accepted feature of commercial competition. Businesses may compare their goods or services with those of competitors to communicate differences in price, quality, performance, effectiveness or other characteristics. The mere fact that a competitor's product or trade mark is identifiable does not automatically make an advertisement unlawful. The legal difficulty arises when comparison crosses into unfair trademark use, false or misleading factual claims, or actionable commercial disparagement.
The Statutory Framework
Sections 29(8) and 30(1) of the Trade Marks Act, 1999 form the principal statutory framework. Section 29(8) addresses advertising of a registered trade mark where the advertising takes unfair advantage of and is contrary to honest practices in industrial or commercial matters, is detrimental to the distinctive character of the mark, or is against its reputation. Section 30(1), conversely, preserves use of a registered trade mark for identifying the proprietor's goods or services where the use is in accordance with honest practices and does not take unfair advantage of, or cause detriment to, the distinctive character or repute of the mark.
Comparative Advertising Is Not Per Se Trademark Infringement
In Reckitt Benckiser Healthcare India Ltd. v. Emami Ltd. & Anr., F.M.A.T. No. 1408 of 2014, Calcutta High Court, judgment dated 29 January 2015, the Court explained that comparative advertising ordinarily identifies a competitor's goods and communicates that the advertiser's own goods are different or superior. The Court nevertheless held that where use of the competitor's registered mark takes unfair advantage, is contrary to honest practices, or is detrimental to the mark's distinctive character or reputation, Section 29(8) may be engaged. Importantly, the appeal was principally concerned with jurisdiction and the statutory framework, and the Court stated that it had not decided the merits of the advertisement.
Sections 29(8) and 30(1) Must Be Read Together
A registered mark does not give its proprietor an absolute right to suppress every reference to that mark in advertising. At the same time, Section 30(1) is not a blanket licence to use a competitor's mark in any manner. The inquiry concerns the purpose and manner of use, honest commercial practice, unfair advantage, and detriment to the distinctive character or repute of the mark.
Pepsi v. Coca-Cola: Important but Historical
Pepsi Co. Inc. v. Hindustan Coca Cola Ltd., 2003 (27) PTC 305 (Delhi), is frequently cited in comparative-advertising discussions. However, the decision arose under the Trade and Merchandise Marks Act, 1958, not the present Trade Marks Act, 1999. It should therefore not be presented as a direct interpretation of current Section 29(8). It remains historically useful for its treatment of comparative advertising and disparagement, including an advertisement that identified Pepsi through visual features and portrayed it in a mocking manner. For current analysis, Sections 29(8) and 30(1) should remain the statutory anchor.
Puffery and Hyperbole
In Hindustan Unilever Ltd. v. Reckitt Benckiser (India) Pvt. Ltd., FAO(OS)(COMM) 157/2021, judgment dated 13 April 2023, the Delhi High Court Division Bench discussed puffery and hyperbole in comparative advertising. Exaggerated praise of one's own product is not automatically actionable merely because it places the competitor in an unfavourable light. The important distinction is between promotional opinion and an assertion of fact capable of verification.
Factual Claims Carry a Greater Evidentiary Burden
Once an advertisement makes a measurable factual comparison—such as claiming that one product lasts longer, removes more stains or performs better—the advertiser should be able to substantiate the claim. In HUL v. Reckitt
Benckiser, the Court treated the relevant comparative claims as statements of fact rather than mere puffery and examined whether the message conveyed to consumers was truthful and non-misleading.
The Overall Message Matters
A comparative advertisement is consumed as a complete communication. Words, images, packaging, product demonstrations, voice-over, sequencing and disclaimers may collectively convey a message that differs from any single sentence. The 2023 HUL v. Reckitt Benckiser judgment emphasised that the overall message delivered by factual statements must not be misleading. An advertiser cannot necessarily defend a campaign by extracting one literally accurate statement while ignoring the impression created by the advertisement as a whole.
Commercial Disparagement: A More Precise Formulation
In Hindustan Unilever Ltd. v. Kwick Living (I) Pvt. Ltd., CS(COMM) 904/2026, Delhi High Court, judgment dated 10 September 2026, the Court explained that some adverse comparison is inherent in comparative advertising. It distinguished a mere derogatory comparison from actionable disparagement involving falsehood, misrepresentation or deception and injury to the competitor's intellectual property or reputation. At the interim stage, the Court found that the impugned campaign went beyond permissible comparative advertising because of its overall representations concerning the alleged harmfulness of HUL products.
Truthful but Unfavourable Comparison
A truthful comparison does not become unlawful merely because the competitor dislikes the result. The September 2026 Kwick Living judgment cautions against equating every unflattering comparison with actionable disparagement. The focus is on whether the representation is false, misleading or deceptive and, where relevant, whether the other ingredients of the pleaded cause of action are established.
Use of a Competitor's Packaging or Trade Mark
A competitor's name, mark or packaging may sometimes be necessary to identify the product being compared. That fact alone does not establish infringement. The question is whether the use falls within the statutory conditions for permissible identification and honest commercial practice, or instead crosses into unfair advantage, detriment to distinctiveness or reputation, misleading representation, or another actionable wrong.
The Competitor Need Not Always Be Named
A competitor may be identifiable by implication through distinctive packaging, product appearance, a recognisable mark or another unmistakable commercial reference. The absence of the competitor's written name is therefore not necessarily decisive. The real question is what the relevant consumer would understand from the advertisement and what message it conveys.
Trademark Infringement and Disparagement Are Not Identical
A comparative-advertising dispute may involve different causes of action depending on the facts, including infringement of a registered trade mark, passing off, commercial disparagement or malicious falsehood. These should not be collapsed into one doctrine. Reckitt Benckiser v. Emami is useful because the Court recognised that a claimant objecting to comparative advertising containing its registered mark may allege Section 29(8) infringement and may also rely on tortious remedies where their requirements are satisfied.
Commercial Speech
In Tata Press Ltd. v. Mahanagar Telephone Nigam Ltd., (1995) 5 SCC 139, the Supreme Court recognised commercial speech as receiving protection under Article 19(1)(a). Comparative-advertising jurisprudence treats this protection as important but not unlimited: commercial speech does not immunise false, misleading, unfair or deceptive advertising.
A Practical Five-Part Test
Before releasing a comparative advertisement, an advertiser should ask: (1) What exactly is being compared? (2) Is the claim opinion/puffery or a factual proposition? (3) If factual, is there reliable substantiation under the conditions represented? (4) Is the competitor's mark or product shown only to identify what is being compared, and is the use consistent with honest commercial practice? (5) What overall message would an ordinary consumer take from the complete advertisement?
Illustration
Suppose Brand A advertises: “In independent testing under specified conditions, Brand A removed more surface stains than Brand B.” If the test genuinely supports the claim and the presentation is not misleading, this is closer to legitimate comparative advertising. By contrast, an advertisement that shows Brand B's product surrounded by alarming imagery and states that Brand B is “unsafe for your family” without adequate evidence creates substantially greater legal risk. The issue is not merely the presence of the competitor's mark but the truth, substantiation and overall commercial message.
Conclusion
Indian law does not prohibit comparative advertising. The Trade Marks Act, 1999 creates a framework in which a competitor's mark may be referred to for identification, while Sections 29(8) and 30(1) impose limits based on honest commercial practice, unfair advantage, detriment to distinctiveness and repute. Pepsi v. Hindustan Coca Cola remains historically important but arose under the 1958 statute; Reckitt Benckiser v. Emami provides a useful current-Act framework; HUL v. 
Reckitt Benckiser demonstrates the distinction between puffery and factual claims; and HUL v. Kwick Living provides a recent illustration that mere unfavourable comparison is not automatically actionable, while false, misleading or deceptive representations may cross the legal boundary. The practical dividing line is therefore not simply comparison versus no comparison, but honest and supportable comparison versus unfair trademark exploitation or misleading commercial communication.

Comparative advertising is an accepted feature of commercial competition. Businesses may compare their goods or services with those of competitors to communicate differences in price, quality, performance, effectiveness or other characteristics. The mere fact that a competitor's product or trade mark is identifiable does not automatically make an advertisement unlawful. The legal difficulty arises when comparison crosses into unfair trademark use, false or misleading factual claims, or actionable commercial disparagement.

The Statutory Framework

Sections 29(8) and 30(1) of the Trade Marks Act, 1999 form the principal statutory framework. Section 29(8) addresses advertising of a registered trade mark where the advertising takes unfair advantage of and is contrary to honest practices in industrial or commercial matters, is detrimental to the distinctive character of the mark, or is against its reputation. Section 30(1), conversely, preserves use of a registered trade mark for identifying the proprietor's goods or services where the use is in accordance with honest practices and does not take unfair advantage of, or cause detriment to, the distinctive character or repute of the mark.

Comparative Advertising Is Not Per Se Trademark Infringement

In Reckitt Benckiser Healthcare India Ltd. v. Emami Ltd. & Anr., F.M.A.T. No. 1408 of 2014, Calcutta High Court, judgment dated 29 January 2015, the Court explained that comparative advertising ordinarily identifies a competitor's goods and communicates that the advertiser's own goods are different or superior. The Court nevertheless held that where use of the competitor's registered mark takes unfair advantage, is contrary to honest practices, or is detrimental to the mark's distinctive character or reputation, Section 29(8) may be engaged. Importantly, the appeal was principally concerned with jurisdiction and the statutory framework, and the Court stated that it had not decided the merits of the advertisement.

Sections 29(8) and 30(1) Must Be Read Together

A registered mark does not give its proprietor an absolute right to suppress every reference to that mark in advertising. At the same time, Section 30(1) is not a blanket licence to use a competitor's mark in any manner. The inquiry concerns the purpose and manner of use, honest commercial practice, unfair advantage, and detriment to the distinctive character or repute of the mark.

Pepsi v. Coca-Cola: Important but Historical

Pepsi Co. Inc. v. Hindustan Coca Cola Ltd., 2003 (27) PTC 305 (Delhi), is frequently cited in comparative-advertising discussions. However, the decision arose under the Trade and Merchandise Marks Act, 1958, not the present Trade Marks Act, 1999. It should therefore not be presented as a direct interpretation of current Section 29(8). It remains historically useful for its treatment of comparative advertising and disparagement, including an advertisement that identified Pepsi through visual features and portrayed it in a mocking manner. For current analysis, Sections 29(8) and 30(1) should remain the statutory anchor.

Puffery and Hyperbole

In Hindustan Unilever Ltd. v. Reckitt Benckiser (India) Pvt. Ltd., FAO(OS)(COMM) 157/2021, judgment dated 13 April 2023, the Delhi High Court Division Bench discussed puffery and hyperbole in comparative advertising. Exaggerated praise of one's own product is not automatically actionable merely because it places the competitor in an unfavourable light. The important distinction is between promotional opinion and an assertion of fact capable of verification.

Factual Claims Carry a Greater Evidentiary Burden

Once an advertisement makes a measurable factual comparison—such as claiming that one product lasts longer, removes more stains or performs better—the advertiser should be able to substantiate the claim. In HUL v. Reckitt

Benckiser, the Court treated the relevant comparative claims as statements of fact rather than mere puffery and examined whether the message conveyed to consumers was truthful and non-misleading.

The Overall Message Matters

A comparative advertisement is consumed as a complete communication. Words, images, packaging, product demonstrations, voice-over, sequencing and disclaimers may collectively convey a message that differs from any single sentence. The 2023 HUL v. Reckitt Benckiser judgment emphasised that the overall message delivered by factual statements must not be misleading. An advertiser cannot necessarily defend a campaign by extracting one literally accurate statement while ignoring the impression created by the advertisement as a whole.

Commercial Disparagement: A More Precise Formulation

In Hindustan Unilever Ltd. v. Kwick Living (I) Pvt. Ltd., CS(COMM) 904/2026, Delhi High Court, judgment dated 10 September 2026, the Court explained that some adverse comparison is inherent in comparative advertising. It distinguished a mere derogatory comparison from actionable disparagement involving falsehood, misrepresentation or deception and injury to the competitor's intellectual property or reputation. At the interim stage, the Court found that the impugned campaign went beyond permissible comparative advertising because of its overall representations concerning the alleged harmfulness of HUL products.

Truthful but Unfavourable Comparison

A truthful comparison does not become unlawful merely because the competitor dislikes the result. The September 2026 Kwick Living judgment cautions against equating every unflattering comparison with actionable disparagement. The focus is on whether the representation is false, misleading or deceptive and, where relevant, whether the other ingredients of the pleaded cause of action are established.

Use of a Competitor's Packaging or Trade Mark

A competitor's name, mark or packaging may sometimes be necessary to identify the product being compared. That fact alone does not establish infringement. The question is whether the use falls within the statutory conditions for permissible identification and honest commercial practice, or instead crosses into unfair advantage, detriment to distinctiveness or reputation, misleading representation, or another actionable wrong.

The Competitor Need Not Always Be Named

A competitor may be identifiable by implication through distinctive packaging, product appearance, a recognisable mark or another unmistakable commercial reference. The absence of the competitor's written name is therefore not necessarily decisive. The real question is what the relevant consumer would understand from the advertisement and what message it conveys.

Trademark Infringement and Disparagement Are Not Identical

A comparative-advertising dispute may involve different causes of action depending on the facts, including infringement of a registered trade mark, passing off, commercial disparagement or malicious falsehood. These should not be collapsed into one doctrine. Reckitt Benckiser v. Emami is useful because the Court recognised that a claimant objecting to comparative advertising containing its registered mark may allege Section 29(8) infringement and may also rely on tortious remedies where their requirements are satisfied.

Commercial Speech

In Tata Press Ltd. v. Mahanagar Telephone Nigam Ltd., (1995) 5 SCC 139, the Supreme Court recognised commercial speech as receiving protection under Article 19(1)(a). Comparative-advertising jurisprudence treats this protection as important but not unlimited: commercial speech does not immunise false, misleading, unfair or deceptive advertising.

A Practical Five-Part Test

Before releasing a comparative advertisement, an advertiser should ask: (1) What exactly is being compared? (2) Is the claim opinion/puffery or a factual proposition? (3) If factual, is there reliable substantiation under the conditions represented? (4) Is the competitor's mark or product shown only to identify what is being compared, and is the use consistent with honest commercial practice? (5) What overall message would an ordinary consumer take from the complete advertisement?

Illustration

Suppose Brand A advertises: “In independent testing under specified conditions, Brand A removed more surface stains than Brand B.” If the test genuinely supports the claim and the presentation is not misleading, this is closer to legitimate comparative advertising. By contrast, an advertisement that shows Brand B's product surrounded by alarming imagery and states that Brand B is “unsafe for your family” without adequate evidence creates substantially greater legal risk. The issue is not merely the presence of the competitor's mark but the truth, substantiation and overall commercial message.

Conclusion

Indian law does not prohibit comparative advertising. The Trade Marks Act, 1999 creates a framework in which a competitor's mark may be referred to for identification, while Sections 29(8) and 30(1) impose limits based on honest commercial practice, unfair advantage, detriment to distinctiveness and repute. Pepsi v. Hindustan Coca Cola remains historically important but arose under the 1958 statute; Reckitt Benckiser v. Emami provides a useful current-Act framework; HUL v.

Reckitt Benckiser demonstrates the distinction between puffery and factual claims; and HUL v. Kwick Living provides a recent illustration that mere unfavourable comparison is not automatically actionable, while false, misleading or deceptive representations may cross the legal boundary. The practical dividing line is therefore not simply comparison versus no comparison, but honest and supportable comparison versus unfair trademark exploitation or misleading commercial communication.
