Reckitt Benckiser (India) Limited v. Hindustan Unilever Limited

In the high-stakes world of consumer goods, competitors constantly try to outflank each other in the marketplace of perception. But what happens when an advertisement takes a not-so-subtle shot at a rival's product? Does every pointed comparison amount to legal slander, or is there room for brands to puff up their own virtues by pointing out the flaws of a category — without naming names? A landmark ruling from the Delhi High Court tackled exactly this question, drawing a surprisingly visual line between fair competition and unfair disparagement.

The dispute pitted two heavyweight consumer goods companies against each other: Reckitt Benckiser (India) Limited as the plaintiff, and Hindustan Unilever Limited as the defendant. At the heart of the conflict was an advertisement run by the defendant that allegedly disparaged the plaintiff's product. Believing the ad crossed the line from competitive comparison into outright denigration, the plaintiff rushed to court seeking an interim injunction to pull the advertisement before it could do further damage. The defendant countered that its ad was a legitimate piece of comparative advertising, designed to highlight the virtues of its own product rather than to slander the plaintiff's specific goods.

The plaintiff argued that the advertisement, when viewed by ordinary consumers, would be understood as a direct attack on its product line. The implication was clear: the ad was designed to make the plaintiff's offering look inferior, thereby causing reputational and commercial harm. The defendant, on the other hand, maintained that the ad targeted a particular class of products defined by specific attributes — and that the plaintiff's product simply did not belong to that class. The legal friction, therefore, centered on whether the ad's messaging was a broadside against the plaintiff's specific goods or a permissible poke at a broader category of competitors.

The Delhi High Court dismissed the plaintiff's request for an interim injunction, siding with the defendant. In a memorable piece of judicial reasoning, the court employed a Venn diagram analogy to make its point: the advertisement targeted products that were both thin and blue, and the plaintiff's product — being thick — simply did not fall within that overlapping circle. Because the attributes of viscosity and color did not align, the court concluded that the ad could not reasonably be read as disparaging the plaintiff's specific goods. The court reaffirmed the principle that comparative advertising is permissible so long as it does not directly denigrate another trader's specific products. With the injunction refused, the defendant was free to continue running its advertisement.

For founders and brand leaders, this case offers a sharp reminder: comparative advertising is a powerful marketing tool, but its legal safety depends on precision. If you are going to take a shot at a competitor's category, make sure the attributes you highlight — whether color, viscosity, size, or any other feature — actually match the rival you are worried about. Conversely, if you believe a competitor is using comparative advertising to undermine your brand, you must be prepared to show that your product genuinely shares the specific characteristics being mocked. Vague associations and category-level jabs are likely to survive legal scrutiny; targeted attacks on identifiable products will not.
