Ruston & Hornsby Ltd. v. The Zamindara Engineering Co.

Supreme Court of India | September 8, 1969 | Civil Appeal No. 1274 of 1966 V. Ramaswami & J.C. Shah, JJ.

Background

Ruston & Hornsby Ltd., a company incorporated in England with its registered office at Lincoln, is engaged in the manufacture and sale of diesel internal combustion engines and their parts. Its Indian subsidiary, Ruston & Hornsby (India) Ltd., was the registered user of the trademark “RUSTON” – registered in India under Registration No. 5120 in Class 7 in respect of internal combustion engines – and manufactured and sold engines under this mark in India.

In June 1955, the appellant discovered that the respondent, Zamindara Engineering Co., a firm also engaged in manufacturing and selling diesel engines, was using the trademark “RUSTAM” on its products. The appellant issued a legal notice calling upon the respondent to cease use of “RUSTAM,” but the respondent replied that no infringement arose because it used the words “RUSTAM INDIA” – not “RUSTAM” alone – and that the suffix “India” sufficiently distinguished its product from the appellant’s.

The appellant filed a suit for permanent injunction in 1956. The trial court (Additional District Judge, Meerut) dismissed the suit in 1958, holding that there was no visual or phonetic similarity between “RUSTON” and “RUSTAM.” On appeal, the Allahabad High Court reversed this finding and held that “RUSTAM” did constitute infringement of “RUSTON.” However, the High Court drew a peculiar distinction: it held that while the bare word “RUSTAM” was an infringement, the combination “RUSTAM INDIA” was not, reasoning that since the appellant’s engines were manufactured in England and the respondent’s in India, the suffix “India” served as a sufficient warning to consumers. The appellant appealed to the Supreme Court.

Issues for Determination

1. Whether, once a mark is found to be deceptively similar to a registered trademark, the addition of a geographical suffix such as “INDIA” to the infringing mark can save it from constituting infringement.
2. Whether the test of likelihood of confusion or deception is the same in both infringement actions and passing off actions where the defendant uses a mark similar (but not identical) to the registered mark.
3. Whether the High Court was correct in permitting the use of “RUSTAM INDIA” despite having found “RUSTAM” to be deceptively similar to “RUSTON.”

Key Holdings of the Court

1. Addition of “INDIA” is of no consequence: Once a mark is found to be deceptively similar to a registered trademark, the addition of a geographical word or suffix cannot cure the infringement or provide a safe harbour to the infringer. The respondent was not entitled to use “RUSTAM INDIA” merely because it had appended the word “India” to an otherwise infringing mark.
2. The respondent was bound by the High Court’s finding: Since the respondent had not appealed against the High Court’s finding that “RUSTAM” was deceptively similar to “RUSTON,” that finding had attained finality and could not be challenged at the Supreme Court stage.
3. Unified test for similarity in infringement and passing off: Where a defendant uses not the exact registered mark but something similar to it, the test of infringement is the same as in a passing off action – namely, the likelihood of confusion or deception in the minds of consumers.
4. Statutory protection is absolute: Once a mark is shown to infringe, the registrant cannot be deprived of relief by something extraneous to the mark itself (such as a distinguishing suffix). Protection under the Trade Marks Act is absolute in this sense.
5. Relief granted: The Supreme Court allowed the appeal and granted the appellant a permanent injunction restraining the respondent from using “RUSTAM” or “RUSTAM INDIA” in connection with its engines, machinery and accessories. Nominal damages of Rs. 100/- were also awarded, along with an order for delivery of price lists, invoices and advertising material bearing the infringing marks.

Statutory Provisions Involved

Section 21, Trade Marks Act, 1940 – The central provision in issue. It grants the registered proprietor of a trademark the exclusive right to use the mark in relation to the goods for which it is registered and deems this right to be infringed by any person who uses a mark identical with or so nearly resembling the registered mark as to be likely to deceive or cause confusion in the course of trade.

Sections 22, 25, 26, 30, 34 and 35, Trade Marks Act, 1940 – Referenced as qualifications and exceptions to the right of infringement, though not directly in issue in this case.

Reasoning of the Court

On the distinction between infringement and passing off: The Court articulated a clear conceptual distinction between the two causes of action. In a passing off action, the question is whether the defendant is selling goods so marked as to lead purchasers to believe they are the plaintiff’s goods. In an infringement action, the question is whether the defendant is using the same mark or a colourable imitation of the registered mark. Infringement is a statutory right dependent on the validity of registration, whereas passing off is a common law action rooted in the protection of goodwill. Critically, in an infringement action, even if the get-up of the defendant’s goods is so different that no consumer would actually be confused, an injunction will still issue the moment the improper use of the mark is proved. The statutory protection is absolute in this sense.

On the unified similarity test: However, the Court drew an important nuance: when the defendant uses not the exact registered mark but something similar to it, the test for infringement converges with the passing off test – both ask whether the similarity is likely to cause confusion or deception. The Court relied on the classic formulation from Saville Perfumery Ltd. v. June Perfect Ltd. to hold that statutory infringement takes place not merely by exact imitation but by use of a mark so nearly resembling the registered mark as to be likely to deceive.

On the “INDIA” suffix defence: The High Court’s reasoning – that the suffix “India” was a sufficient warning because one product was manufactured in England and the other in India – was squarely rejected. The Court reasoned that once deceptive resemblance between the two marks is established, nothing extraneous to the marks themselves (including a geographical qualifier) can provide a defence. To hold otherwise would be to allow infringers to easily circumvent trademark protection by appending common words to otherwise infringing marks.

Doctrinal Significance

1. Convergence of the infringement and passing off tests for similar (non-identical) marks: This judgment is a foundational authority for the proposition that where the defendant uses a mark similar but not identical to the registered mark, the applicable test in an infringement action is the same as in passing off – namely, likelihood of confusion. This convergence has been consistently followed in subsequent Indian trademark jurisprudence.

2. Absolute statutory protection – extraneous matter irrelevant: The Court reinforced that statutory infringement protection under trademark law is absolute. Once infringement of a registered mark is established, the defendant cannot escape liability by pointing to something outside the mark itself – whether it is different packaging, a different country of origin or an added suffix. This principle has become a cornerstone of Indian trademark law.

3. Geographical suffixes cannot save an infringing mark: The judgment establishes that the addition of a purely geographical word like “India” to an otherwise deceptively similar mark does not distinguish it for the purposes of trademark law. This holding remains highly relevant in the context of localised variants of globally known marks.

4. Finality of unchallenged findings: The case also illustrates an important procedural principle – that a party who does not appeal against an adverse finding on a specific issue is bound by it and cannot raise it at a higher court. This prevents piecemeal challenges to complex multi-issue judgments.

5. Precedential value in the diesel/industrial goods sector: The case is significant in the context of industrial and engineering goods where buyers, though not illiterate, may still be confused by phonetically similar brand names, demonstrating that the protective ambit of trademark law extends beyond consumer goods to industrial machinery markets.
