A domain incorporating the Yahoo name, aimed at Indian users and offering services of a similar kind, appeared in the late 1990s. Yahoo went to the Delhi High Court. The awkward fact for the plaintiff was that its trademark was not registered in India at that point, so the claim could not be brought as infringement and had to be brought in passing off instead.
The IP move
The court granted an interim injunction in 1999. It held that a domain name performs a function well beyond that of a technical address, that internet users encountering the two would be likely to assume some connection between them, and that adding a geographic word to a well-known name does nothing to dispel that confusion. If anything, appending a country name suggests an official local presence, which makes matters worse rather than better. It is generally regarded as India's first cybersquatting decision.
Yahoo won, but it is worth being precise about what winning required. It had to prove its reputation, prove likely confusion, and litigate for an interim order, all of which is avoidable when you hold a registration and you catch the problem early enough to send a letter instead of a plaint.
The lasting significance of the case is that it opened a category. Once domain names were recognised as identifiers worth protecting, watching for them stopped being an IT housekeeping matter and became part of protecting the brand, sitting alongside the trademark register rather than apart from it.
The takeaways
Your brand can be taken in places that have no examiner and no opposition period, which means nobody is going to notify you that it happened.
Adding a country name, a hyphen, a plural or a different extension does not make a copy lawful, and it does make it much easier to miss.
Watching is a standing process across the trademark register, the marketplaces, the app stores and the domain space, not an annual tidy-up.
Early detection converts a lawsuit into a takedown request or a transfer, which is a difference measured in years and lakhs.
The cheapest enforcement is the one that happens before the other party has built anything on the name.
The lesson for your business
Put your marks under an active watch and give a named person ownership of the calendar behind it: renewal dates for every registration and every domain, a registry watch for confusingly similar applications during the window when they can still be opposed, and periodic sweeps of domains, app stores and marketplace listings. The cost of watching for a decade is smaller than the cost of one contested injunction, and watching is the only mechanism that tells you in time to act while acting is still cheap.
