Trademark Infringement vs. Passing Off: A Comparative Legal Analysis

Introduction

A trademark is a distinctive sign that identifies the source of goods or services and distinguishes them from those of others. The Trade Marks Act, 1999 defines a trademark as a mark capable of graphical representation and capable of distinguishing the goods or services of one person from those of others.¹ Trademarks serve two primary functions: protecting consumer interests by preventing confusion and safeguarding the goodwill built by businesses in their brands.

Indian trademark law adopts a dual system of protection. First, it provides statutory protection to registered trademarks through an action for infringement.² Second, it preserves the common law remedy of passing off to protect unregistered marks and business goodwill.³ Although both remedies aim to prevent deception and unfair competition, they differ significantly in their legal basis, evidentiary requirements, and scope of protection.

Trademark Infringement: The Statutory Remedy

Trademark infringement is a statutory cause of action available only to the registered proprietor or a permitted user of a trademark. Section 28(1) of the Trade Marks Act grants the registered proprietor the exclusive right to use the trademark and to obtain relief in respect of infringement.⁴ Section 29 defines infringement. It provides that a registered trademark is infringed when a person, without authorisation, uses in the course of trade a mark that is identical with or deceptively similar to the registered trademark in relation to goods or services for which the mark is registered, in a manner likely to cause confusion.⁵

The essential elements of infringement are:

1. Valid registration of the trademark;
2. Unauthorised use by the defendant;
3. Identity or deceptive similarity between the marks;
4. Likelihood of confusion or association.

Under Section 29(3), when identical marks are used for identical goods, the court shall presume likelihood of confusion.⁶ Further, Section 29(4) extends protection to well-known trademarks even in relation to dissimilar goods, where such use takes unfair advantage of or is detrimental to the distinctive character or reputation of the registered mark.⁷

Registration carries a presumption of validity under Section 31.⁸ Therefore, in an infringement suit, the plaintiff need not independently prove goodwill or reputation. Once the defendant’s use of the mark is established, the burden shifts to the defendant to disprove confusion or to rely upon statutory defences under Section 30.⁹

The Supreme Court clarified in K.P. Durga Dutt Sharma v. Navaratna Pharmaceutical Laboratories¹⁰ that in infringement actions, if the essential features of the plaintiff’s registered mark are adopted by the defendant, differences in get-up, packing, or additional material are immaterial. The focus remains on the similarity of the mark itself.

Section 135 provides remedies for infringement, including injunction, damages or an account of profits, and delivery-up or destruction of infringing goods.¹¹ Thus, infringement is a relatively straightforward statutory action supported by presumptions in favour of the registered proprietor.

Passing Off: The Common Law Remedy

Passing off is a common law tort designed to protect business goodwill against misrepresentation. Section 27(2) of the Act expressly preserves the right to institute an action for passing off even in respect of unregistered trademarks.¹²

Unlike infringement, passing off does not protect a statutory monopoly but safeguards commercial reputation. The classical trinity of passing off consists of:

1. Goodwill or reputation of the plaintiff;
2. Misrepresentation by the defendant;
3. Damage or likelihood of damage to the plaintiff’s goodwill.

The principle underlying passing off was famously articulated in Perry v. Truefitt (1842),¹³ where it was observed that no person has the right to represent his goods as those of another.

In India, the Supreme Court elaborated the doctrine in Cadila Healthcare Ltd. v. Cadila Pharmaceuticals Ltd.¹⁴ The Court emphasised that deceptive similarity must be assessed from the perspective of an average consumer with imperfect recollection. It laid down multiple factors to determine likelihood of confusion, including the nature of the marks, the degree of resemblance, the class of purchasers, the nature of goods, and the surrounding circumstances.

In passing off actions, the plaintiff bears a heavier evidentiary burden than in infringement suits. The plaintiff must prove prior use, established reputation, and actual or probable deception. There is no presumption of validity as exists in statutory infringement. The focus is not merely on the similarity of marks but on the overall presentation, trade dress, and consumer perception. If successful, the plaintiff may obtain remedies similar to those available in infringement proceedings under Section 135, including injunction and damages.

Comparative Analysis

1. Nature of Right

Trademark infringement is a statutory remedy arising from registration under the Trade Marks Act. Passing off is a common law tort grounded in the protection of goodwill and the prevention of deceit.

2. Requirement of Registration

Registration is mandatory for an infringement action. Without registration, a proprietor cannot sue for infringement.¹⁵ Passing off, however, is available irrespective of registration.

3. Burden of Proof

In infringement, registration provides prima facie validity.¹⁶ The plaintiff must establish similarity and unauthorised use, after which statutory presumptions operate in the plaintiff’s favour. In passing off, the plaintiff must independently establish goodwill, misrepresentation, and damage. There are no statutory presumptions.

4. Role of Similarity and Get-Up

In infringement, the similarity of the essential features of the registered mark is decisive. As held in Durga Dutt Sharma,¹⁷ differences in packaging are immaterial once the essential features are copied. In passing off, overall get-up, trade dress, and presentation are crucial. The defendant may escape liability if sufficient distinguishing features prevent consumer confusion.

5. Scope of Protection

Infringement protection is confined to the goods or services for which the mark is registered, subject to extended protection for well-known marks under Section 29(4).¹⁸ Passing off protection attaches to the trader’s goodwill across goods or services once reputation is established.

6. Practical Strategy

In practice, plaintiffs often plead both infringement and passing off together. This ensures protection even if registration is challenged or held invalid.

Judicial Interpretation

Indian courts have consistently emphasised the distinction between infringement and passing off.

In K.P. Durga Dutt Sharma v. Navaratna Pharmaceutical Laboratories,¹⁹ the Supreme Court clarified that infringement requires proof of use of the registered mark and that deception may be presumed in cases of substantial identity. Passing off, however, is an action sounding in deceit, requiring independent proof of misrepresentation.

In Cadila Healthcare Ltd. v. Cadila Pharmaceuticals Ltd.,²⁰ the Court introduced a detailed multi-factor test for deceptive similarity, placing particular emphasis on stricter scrutiny in pharmaceutical cases due to the public health implications involved.

These decisions form the cornerstone of Indian trademark jurisprudence and clearly demarcate the boundaries between statutory and common law protection.

Conclusion

Trademark infringement and passing off share the objective of preventing consumer confusion and unfair competition, yet they differ fundamentally in origin, requirements, and proof. Infringement is a statutory remedy protecting registered trademarks with presumptive validity and streamlined proof requirements. Passing off is a common law remedy protecting business goodwill through independent proof of misrepresentation and damage.

The coexistence of these remedies ensures comprehensive protection of trademarks in India. While infringement safeguards the formally registered right, passing off protects the broader commercial reputation of traders. Together, they form an integrated framework that upholds both statutory monopoly and equitable fairness in trade.
