Ruston & Hornsby Ltd. v. Zamindara Engineering Co.

A leading trademark case establishing that addition of a geographical or descriptive word does not necessarily distinguish a deceptively similar trademark.

Short Description About the Case

This case concerned the trademark “RUSTON” and the defendant's use of “RUSTAM INDIA.” Ruston & Hornsby Ltd. alleged trademark infringement. The Supreme Court considered whether adding the word “INDIA” to a deceptively similar mark was sufficient to distinguish it from the plaintiff's trademark. The Court held that it was not.

Facts

Ruston & Hornsby Ltd. was the proprietor of the trademark “RUSTON”, used in relation to diesel engines.

Zamindara Engineering Co. manufactured and sold diesel engines under the mark “RUSTAM INDIA.”

The plaintiff alleged that “RUSTAM INDIA” was deceptively similar to its registered trademark “RUSTON” and therefore constituted trademark infringement.

The defendant argued that the addition of the word “INDIA” sufficiently distinguished its mark from the plaintiff's trademark.

Findings

The Supreme Court compared the competing marks from the perspective of their overall commercial impression.

The Court held that the essential feature of the defendant's mark was “RUSTAM”, which was deceptively similar to “RUSTON.”

The mere addition of the word “INDIA” did not remove the likelihood of confusion or deception.

The Court therefore rejected the argument that adding another word automatically makes an otherwise deceptively similar trademark legally distinguishable.

Suggestion

This case is highly useful in matters involving trademark infringement, deceptive similarity, addition of suffixes or prefixes, dominant features, and comparison of competing marks.

It can be cited where a defendant attempts to avoid infringement by adding words such as “India,” “Co.,” “Ltd.,” “International,” or other descriptive/geographical expressions to a similar trademark.

For practical legal use, this case supports the principle that a minor addition to a deceptively similar trademark does not necessarily cure infringement when the essential feature of the mark remains similar.

Judgment

The Supreme Court upheld the finding of trademark infringement against the defendant.

It held that “RUSTAM INDIA” was deceptively similar to “RUSTON”, and the addition of “INDIA” did not sufficiently distinguish the defendant's mark.

The defendant was therefore restrained from using the infringing mark.
