Central Park Estates Pvt. Ltd. v. Keystone Realtors Pvt Ltd

In the high-stakes world of real estate, a brand name can make or break a project. But what happens when two developers stake their claim on the same iconic phrase? This case is a masterclass in why trademark registration, while powerful, is not an invincible shield—especially when the other side has been building their reputation long before the paperwork was filed. For founders and IP professionals, the lesson is clear: in trademark battles, equity often trumps exclusivity.

Central Park Estates Pvt. Ltd. and its associates, the appellants, held registered trademark rights in the name 'Central Park'. They approached the Delhi High Court seeking to restrain Keystone Realtors Pvt Ltd. and another party from using a similar mark. Keystone Realtors, the respondent, had been operating under the brand 'Rustomjee Central Park' for their real estate project. The appellants argued that their registered rights entitled them to protection against any confusingly similar use. Keystone, however, countered that they had adopted the mark in a bona fide manner, had invested substantially in their project, and had established a significant commercial presence—all before the appellants' claims could override their existing operations.

The appellants leaned heavily on the strength of their registered trademark, arguing that statutory ownership should automatically translate into the right to exclude others from using a deceptively similar mark. They sought an absolute injunction to halt Keystone's use of 'Rustomjee Central Park' entirely. Keystone, on the other hand, marshaled evidence of their prior commercial use, the scale of their investment in the project, and the bona fide nature of their adoption of the mark. They also highlighted the practical reality that an absolute injunction would severely disrupt their ongoing operations and impact existing occupants and purchasers who had already committed to the project. The legal friction centered on a classic IP dilemma: does a registered proprietor automatically win, or should the court weigh the equities of prior use and established business interests?

The Delhi High Court dismissed the appeal filed by Central Park Estates, choosing to uphold the limited interim injunction that had been granted in favor of Keystone Realtors. The court acknowledged the appellants' registered rights but found that the respondents had successfully demonstrated bona fide prior use coupled with substantial investment in their project. Balancing the equities, the court ruled that Keystone could continue using 'Rustomjee Central Park', subject to one critical condition: the prominence of the words 'Central Park' must be maintained in their branding. This conditional permission reflected the court's effort to protect both parties' legitimate interests without granting either side an absolute victory.

For founders, startup leaders, and IP professionals, this case delivers a sobering reminder: trademark registration is a powerful right, but it is not an absolute guarantee of market exclusivity. Before adopting a brand name, conduct thorough clearance searches—not just for registered marks, but for unregistered prior users who may have built substantial goodwill. If you are the registered owner, be prepared to demonstrate that your mark has been actively used and enforced, because courts will weigh the equities heavily in favor of parties who have invested significantly in their brand. And if you find yourself on the defending side, document your adoption timeline, investments, and commercial use meticulously—these facts can be the difference between being shut down and being allowed to operate under reasonable conditions.
