Phonetic Similarity as a Ground for Trademark Infringement and Passing Off: A Perspective for Glocal Professional

Introduction

In the realm of trademark law, the question often arises: Can two brand names that sound alike, but look different, still be considered deceptively similar? For companies like Glocal Professional, understanding this principle is vital to protecting brand identity and consumer trust.

Legal Foundation: Phonetic Similarity in Indian Trademark Law

Indian trademark law, particularly Section 29(9) of the Trade Marks Act, 1999, explicitly recognizes that infringement can occur not only through visual imitation but also through phonetic (sound-based) similarity. This means that if a competitor uses a name that sounds similar to "Glocal Professional," even if it is spelled differently or has a different logo, it could still be considered an infringement if it causes confusion among consumers.

The courts have repeatedly emphasized that both the eye and the ear must be engaged when comparing trademarks. The Supreme Court, in landmark cases such as Amritdhara Pharmacy v. Satya Deo Gupta and Cadila Healthcare Ltd. v. Cadila Pharmaceuticals Ltd., has held that the test for deceptive similarity must consider the imperfect recollection of the average consumer-someone who may not remember the exact spelling or appearance but is likely to recall how the name sounds.

Judicial Approach and Key Precedents

• Phonetic Similarity Alone Can Suffice: Courts have established that phonetic similarity alone can be sufficient to prove trademark infringement and passing off, even if there are clear visual differences between the marks. For example, in the Chanel Ltd. v. Sunder Chemicals Agarbati Works (P) Ltd. case, the Delhi High Court granted an injunction based solely on the phonetic closeness of "CHANEL" and "SHANELLE," despite differences in spelling and packaging.

• Average Consumer Standard: The assessment is made from the perspective of an average person with imperfect memory, not an expert or someone making a side-by-side comparison.

• Market Context: The risk of confusion increases when the goods or services are similar or target the same market segment, making phonetic similarity a more critical factor.

Practical Implications for Glocal Professional

• Trademark Searches: When Glocal Professional considers new product names or brand extensions, it is essential to conduct not only visual but also phonetic searches to identify potential conflicts.

• Brand Protection: If another company adopts a name that sounds similar to "Glocal Professional," even with different spelling or design, Glocal Professional can seek legal remedies. The courts may grant injunctions to prevent such use if there is a likelihood of confusion.

• Passing Off: In addition to statutory infringement, common law passing off protects against unfair competition. If phonetic similarity misleads consumers into associating another business with Glocal Professional, it can amount to passing off, even without identical marks.

Recent Cases and Judicial Trends

• In INSEAD v. INSAID, the Delhi High Court found that the use of "INSAID" was phonetically similar to "INSEAD" and thus likely to cause confusion, leading to the cancellation of the respondent's mark.

• In Winmedicare Ltd. v. Somacare Laboratories, the marks "DICLOMOL" and "DICMOL" were found confusingly similar due to their sound, resulting in an injunction.

• The courts have consistently held that minor visual differences do not negate the risk of confusion if the names are aurally similar and the products are related.

Conclusion

For Glocal Professional, the law is clear: phonetic similarity alone can be a sufficient basis for trademark infringement and passing off actions, even if visual differences exist. Protecting your brand means being vigilant not just about how your name looks, but also how it sounds in the marketplace. This approach ensures that consumer trust is maintained and the distinctiveness of Glocal Professional is preserved against misleading imitations
