Introduction
One of the most common misconceptions about trademark law is that similarity automatically leads to infringement. In practice, Indian courts undertake a far more detailed inquiry. A trademark dispute is not decided merely by placing two marks side by side and identifying common letters, words, or sounds.
The central question is whether the use of one mark is likely to cause confusion regarding the source of the goods or services. To answer that question, courts examine the nature of the products, the class of consumers, trade channels, market realities, prior use, reputation, and the overall impression created by the competing marks. Two notable trademark disputes show why similar marks can sometimes coexist without infringing each other.
Lesson One: Registration Does Not Create a Monopoly Over an Entire Class
The Nandhini Deluxe Case
The Supreme Court's decision in Nandhini Deluxe v. Karnataka Co-operative Milk Producers Federation Ltd. is one of the most important decisions on trademark coexistence in India.
The dispute arose between Karnataka Co-operative Milk Producers Federation, the proprietor of the well-known "NANDINI" mark used for milk and dairy products, and Nandhini Deluxe, a restaurant business that sought registration of the mark "NANDHINI" for goods associated with its restaurant operations.
The Federation argued that its earlier registration entitled it to prevent registration of the later mark. The Supreme Court disagreed and permitted registration.
The Court emphasized several factors:
The marks were not identical.
The businesses operated in different commercial spheres.
The Federation's primary reputation was in dairy products.
Consumers were unlikely to assume that a restaurant operating under the name "NANDHINI" originated from the dairy producer.
The judgment clarified an important principle: ownership of a trademark does not automatically confer exclusive rights over every product or service falling within a broad trademark classification.
Lesson Two: Surnames Occupy a Special Position in Trademark Law
The Goenka Dispute
The Delhi High Court's decision in Goenka Institute of Education & Research v. Anjani Kumar Goenka concerned the use of the surname "Goenka" in the education sector.
The dispute raised a recurring trademark question: can a person or institution claim exclusive rights over a surname that is shared by many individuals?
The Court recognized that surnames often have limited inherent distinctiveness. At the same time, a surname may acquire trademark significance if prolonged use causes the public to associate it with a particular source. The Court therefore examined issues such as prior use, goodwill, acquired distinctiveness, and the manner in which the competing parties were presenting themselves in the marketplace.
The decision demonstrates that trademark protection for surnames exists on a spectrum. A surname cannot automatically be monopolized merely because it appears in a registered mark. Equally, once a surname acquires substantial goodwill and secondary meaning, courts may grant protection against confusing uses.
Lesson Three: Similarity Is Only One Part of the Test
Trademark litigation often focuses on phonetic resemblance. While phonetic similarity is important, it is rarely decisive on its own.
Indian courts generally compare marks as a whole. They examine:
Visual appearance.
Structural composition.
Pronunciation.
Nature of goods and services.
Consumer base.
Trade channels.
Overall commercial impression.
A mark that appears similar in isolation may nevertheless coexist with another if consumers are unlikely to assume a common commercial origin.
Likewise, marks that differ in spelling may still infringe if their overall impression creates confusion.
Honest Concurrent Use and Section 12
Another important feature of Indian trademark law is the doctrine of honest concurrent use embodied in Section 12 of the Trade Marks Act, 1999.
The provision recognizes that in certain circumstances multiple traders may independently and honestly adopt similar marks. Where there has been bona fide adoption, concurrent use, and limited risk of confusion, registration may be permitted subject to conditions imposed by the Registrar.
Section 12 does not automatically validate similar marks. Instead, it provides a mechanism through which coexistence may be legally recognized where the facts justify such an outcome.
Conclusion
Trademark law is ultimately concerned with consumer perception rather than mechanical comparison. The decisions in Nandhini Deluxe and Goenka demonstrate that similarity alone does not determine infringement. Courts evaluate the entire commercial context, including the nature of the business, the reputation of the mark, the likelihood of confusion, and the honesty of adoption.
Similar trademarks may coexist where consumers are unlikely to be misled, but even minor similarities may become actionable when they create confusion regarding the source of goods or services.
