A restaurant brand built across a century. A competitor that changed exactly one letter and replicated everything else — the font, the colour, the look, the feel.

The Delhi High Court had a straightforward question before it: does changing one letter create a different brand?

It does not. And the reasoning behind that conclusion matters to anyone who owns a brand in India's food-service sector — or in any consumer-facing business where recognition lives as much in sound as in appearance.

What Was Being Copied — and Why It Mattered

Karim Hotels Pvt Ltd has operated under the KARIM'S mark since 1913. The trademark has been registered in Class 43 — restaurant and food services — since December 1998. It is among the most recognised restaurant brands in the country.

The defendants adopted KARIN'S. The difference: a single transposed letter. They then reproduced the font, colour scheme, and overall visual identity of the Karim's brand, and operated in the same food-service segment.

The Trade Marks Act, 1999 prohibits the use of a mark that is deceptively similar to a registered mark. The test is not whether an expert, comparing the two marks side by side, can tell them apart. The test is the impression left on an ordinary consumer going about their daily life — the person who hears a recommendation, reads a signboard, or calls ahead for a table.

What the Court Found

The two marks are indistinguishable when spoken aloud. The trade dress was deliberately copied, not coincidentally similar. The commercial field is identical.

Deceptive similarity was made out on every dimension the law examines. No single dimension needed to carry the conclusion on its own.

Permanent injunction granted. The defendants were barred from using KARIN'S or any mark identical with or deceptively similar to KARIM'S.

Why This Actually Matters

Trademark protection is often thought of as a visual exercise. The lesson here is that it is equally phonetic.

In a market where customers ask for restaurant recommendations by name, search by sound, and pass references word of mouth, the way a brand sounds is as much its identity as how it looks. A mark that sounds the same — regardless of how it is spelled — is capable of deceiving the very consumer the Trade Marks Act is designed to protect.

The ruling also puts on record something courts have implied but rarely stated this directly: replicating trade dress alongside a phonetically similar mark is not a bona fide adoption. It is evidence of intent.

The Takeaway

If your brand is registered and someone is operating under a mark that sounds like yours — even if the spelling is technically different — you have a basis to act. Sound, appearance, and trade class are examined together, and none of the three needs to be a perfect copy.

And if you are on the other side of that question: a single-letter change does not create a new brand. It creates a problem.
