Satyam Infoway Ltd. v Sifynet Solutions Pvt. Ltd.

• Satyam Infoway Ltd (later Sify Technologies) was one of India's earliest ISPs, operating since 1998 under the brand "Sify"
• It held the domain sify.com and provided internet access, web hosting, and portal services
• The respondent registered "siffynet.com" and offered competing internet and portal services
• The phonetic similarity between "Sify" and "Siffy" was apparent
• The Madras High Court granted an interim injunction; the respondent appealed

1. Whether a domain name is a form of intellectual property protectable by law
2. Whether the passing off action extends to domain names
3. What principles govern domain name disputes in the absence of specific legislation

• Domain names have evolved beyond mere internet addresses; they are valuable business identifiers and indicators of source
• The legal principles governing trademarks (passing off, deceptive similarity, likelihood of confusion) apply to domain names
• "siffynet.com" is phonetically and visually similar to "sify.com" and is likely to cause confusion among consumers of internet services
• Injunction upheld; the respondent restrained from using the domain
• Courts must consider: similarity of marks, nature of goods/services, likelihood of confusion, intent of the adopter

With the growth of e-commerce, domain names serve the same purpose as trademarks: they identify the source of services and distinguish one provider from another. When a domain name is used in connection with a business, it acquires the character of a trade identifier. The action of passing off provides adequate remedy for domain name disputes without requiring statutory amendment.
