Comparative advertising allows businesses to highlight the advantages of their products by referring to competing products. However, a campaign can create legal exposure when it misuses a competitor’s trademark, makes misleading claims or damages the reputation of a rival brand. Understanding trademark infringement in advertising is therefore essential for businesses planning product comparisons, promotional campaigns and competitive marketing strategies in India. The law does not prohibit every reference to a competitor. It recognises the value of truthful comparisons while setting limits on unfair commercial conduct. The challenge is to distinguish legitimate product promotion from misleading comparison, trademark misuse and product disparagement.
1. What Is Comparative Advertising?
Comparative advertising is a promotional technique in which a business compares its products or services with those of a competitor. The comparison may refer to price, quality, performance, ingredients, durability, features or other commercial attributes. A business may identify a competitor directly by name or trademark. It may also refer to a rival indirectly through packaging, product appearance, slogans or other recognisable features. Such comparisons can help consumers make informed purchasing decisions and encourage competition. However, an advertisement must present its claims fairly. A company cannot use a comparison as an opportunity to misrepresent a competitor’s product, create confusion about commercial origin or exploit another brand’s reputation.
2. What Does Indian Trademark Law Say About Comparative Advertising?
The Trade Marks Act, 1999 provides the central legal framework for assessing trademark use in advertisements. Section 29(8) specifically addresses infringement through advertising. A registered trademark may be infringed when it is used in advertising if 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 trademark.
- Is against the reputation of the trademark.
Section 30(1) provides an important limitation. Use of a registered trademark to identify the goods or services of its proprietor may be permissible where the use accords with honest practices in industrial or commercial matters and does not take unfair advantage of, or cause detriment to, the mark’s distinctive character or repute. These provisions recognise a balance. Competitors should be able to identify products for genuine comparison, but they cannot use another brand’s reputation unfairly or undermine its distinctiveness through dishonest advertising.
3. When Does Comparative Advertising Become Trademark Infringement?
A comparative advertisement does not automatically infringe a trademark merely because it mentions a competitor’s brand. The circumstances and manner of use are important. A legal issue may arise when an advertiser uses a competitor’s mark in a way which suggests an association between the two businesses, takes unfair advantage of the mark’s reputation or damages its distinctive character. An advertisement may also create infringement concerns if it uses a rival’s logo, slogan or other protected brand element beyond what is reasonably required for identification.
For example, a company may compare the price of its product with a competitor’s product using accurate and verifiable information. However, using the competitor’s logo prominently, presenting its product as inferior without reliable evidence or creating the impression of an official association may create legal exposure. The question is not simply whether a competitor’s trademark appears in the advertisement. It is whether the use satisfies the statutory conditions and remains consistent with honest commercial practices.
4. The Difference Between Puffery and Product Disparagement
Puffery refers to promotional exaggeration used to present a product favourably. Statements such as “the best in the market” or “unmatched performance” may be treated as ordinary advertising opinion when consumers are unlikely to interpret them as precise factual claims. Product disparagement is different. It occurs when an advertisement unfairly belittles a competitor’s product through misleading statements, false comparisons or an overall presentation which damages its reputation.
Indian courts have recognised a business’s freedom to promote its own products. However, an advertiser cannot cross the line by making false or misleading statements about a rival. In Pepsi Co. Inc. v. Hindustan Coca Cola Ltd., 2003 (27) PTC 305 (Del), the Delhi High Court examined advertisements involving Pepsi and Coca Cola products. The Court recognised the right of a trader to claim its goods are better than those of a competitor. However, it also emphasised the limits of disparagement. A business may praise its own products, but it cannot unfairly denigrate the rival’s goods. The decision remains an important reference for understanding comparative advertising and product disparagement in India.
5. Important Indian Judgments on Comparative Advertising
Indian courts have developed practical principles through disputes involving consumer products, household goods and competing advertising campaigns.
a) Hindustan Unilever Ltd. v. Reckitt Benckiser (India) Ltd. (2013)
The Calcutta High Court considered competing advertisements involving VIM and Dettol Healthy Kitchen Gel. The dispute concerned claims about germ removal and the presentation of competing dishwashing products. The Court examined the advertisements individually and considered whether the comparisons were fair, accurate and capable of misleading consumers. The decision illustrates how courts assess the complete message conveyed by an advertisement rather than relying only on the words used in isolation.
b) Havells India Ltd. v. Amritanshu Khaitan, CS(OS) 107/2015, decided on 17 March 2015
The Delhi High Court considered a comparison between Eveready and Havells LED bulbs. The dispute involved claims about brightness, price and product performance. The Court observed that comparative advertising should involve products serving the same needs and should compare material, relevant, verifiable and representative features. It also emphasised the importance of honest commercial practices under Sections 29(8) and 30(1) of the Trade Marks Act. The decision demonstrates why selective comparisons can create legal problems. An advertisement may mislead consumers if it highlights one favourable feature while concealing other important factors which materially affect the comparison.
c) Reckitt Benckiser (India) Pvt. Ltd. v. Wipro Enterprises (P) Ltd., 2023:DHC:3418
In this Delhi High Court dispute, Reckitt challenged a Santoor Hand Wash advertisement which referred to an ordinary hand wash and showed a bottle resembling Dettol Hand Wash. The Court examined the advertisement’s storyline, visual presentation and implied message. Its judgment discussed the principles governing comparative advertising, including the distinction between permissible promotion and unfair disparagement. The decision is particularly useful for businesses using visual references to competitors. Even where an advertisement does not repeatedly name a rival, the product may be identifiable through its packaging or other distinctive features.
6. How Should Businesses Make Fair and Defensible Comparisons?
Businesses should establish a review process before releasing comparative advertisements. The first step is to identify precisely what the campaign intends to compare. Products should serve the same needs or have a comparable purpose. Comparing unrelated products can create a misleading impression. The next step is to verify every factual claim. Performance, price, quality, durability and ingredient comparisons should be supported by reliable and current evidence. Testing should use consistent methods and comparable conditions. The business should retain the underlying reports, product samples, dates and other supporting records.
The advertisement should also present the results fairly. A company should not select only favourable measurements while concealing information likely to change the consumer’s understanding. Disclaimers may clarify a claim, but they cannot correct a fundamentally misleading message. Finally, the creative presentation should be reviewed. Competitor logos, brand names, packaging, slogans and other distinctive elements should be used only where necessary and in a manner consistent with applicable law.
7. Other Laws Which May Apply to Comparative Advertising
Trademark law is not the only legal framework governing advertising in India. Section 2(28) of the Consumer Protection Act, 2019 defines misleading advertisements. It covers advertisements which falsely describe a product, give false guarantees, mislead consumers about a product’s nature or quality, convey representations amounting to unfair trade practices or deliberately conceal important information.
The Central Consumer Protection Authority has also issued the Guidelines for Prevention of Misleading Advertisements and Endorsements for Misleading Advertisements, 2022. These guidelines address conditions for valid advertisements, disclaimers, endorsements and the responsibilities of advertisers and other participants.
The Advertising Standards Council of India also provides a self regulatory framework. Its code permits comparative advertisements where comparisons are factual, accurate and capable of substantiation, while prohibiting unfair denigration and misleading presentation. Businesses should therefore assess advertising campaigns under trademark law, consumer protection requirements and applicable industry standards. A campaign may avoid trademark infringement yet still raise concerns under consumer protection law if its claims are misleading.
8. What Can a Business Do If a Competitor Publishes a Misleading Advertisement?
A business concerned about a competitor’s campaign should first preserve the relevant evidence. This may include television recordings, social media posts, print advertisements, website captures, product samples and the dates on which the campaign appeared. The next step is to identify the legal basis for a complaint. The issue may involve unauthorised trademark use, misleading factual claims, product disparagement or a combination of these concerns.
Depending on the circumstances, the affected business may consider a legal notice, an advertising standards complaint, a consumer protection complaint or court proceedings. Section 135 of the Trade Marks Act provides for civil remedies in infringement and passing off actions, including injunctions, damages or an account of profits.
Urgent interim relief may be relevant where an advertisement is continuing to cause serious harm. However, a court will consider the evidence, the legal claim and the requirements for interim relief before granting an injunction. Businesses seeking to understand trademark infringement in advertising should examine the statutory requirements carefully rather than assuming every unfavourable comparison is unlawful.
9. Why Legal Review Should Be Part of Advertising Strategy
Legal review should take place before a comparative campaign is published, not only after a competitor objects. Marketing teams may focus on creative impact and brand positioning, while legal teams assess the accuracy, fairness and intellectual property implications of the message. A structured approval process can help identify problematic claims, unsupported comparisons and unnecessary use of competitor trademarks. It can also ensure the business retains evidence supporting its advertising statements.
Seeking advice from trademark lawyers for advertising matters can help businesses assess the risks associated with comparative campaigns, review proposed claims and respond to disputes. This is particularly important in sectors where product performance claims influence consumer safety, health or significant purchasing decisions.
Conclusion
Comparative advertising can be an effective way to communicate product advantages and help consumers make informed decisions. However, businesses must ensure their campaigns remain factual, fair and consistent with honest commercial practices. Indian law permits legitimate comparison but does not protect misleading claims, unfair trademark use or product disparagement. By verifying claims, presenting comparisons objectively and reviewing creative material before publication, businesses can reduce legal exposure while maintaining effective advertising strategies.
