Drs Educational Society & Ors.vsRegistrar Of Trade Marks & Anr.

The Delhi High Court dismissed a writ petition filed by Drs Educational Society challenging the registration of the 'DRS' trademark. The petitioners argued that the registration was erroneous because the applicant had previously withdrawn their application, but the Registrar failed to act on this withdrawal. However, the court held that administrative lapses do not invalidate an accrued statutory right. It emphasized that disputes over trademark validity must be pursued through specific remedies under the Trademarks Act, 1999, rather than via a writ petition.

Tirupati Structurals LimitedvsJai Prakash Singhal

The Delhi High Court granted an interim injunction in favor of Tirupati Structurals Limited against Jai Prakash Singhal, finding that the defendant's use of 'MM TIRUPATI' was deceptively similar to the plaintiff's established mark 'TSL-TIRUPATI'. The court held that despite minor differences in prefixes, the identical and prominent shared element 'TIRUPATI', coupled with the similarity in goods (pipes and fittings), created a high likelihood of consumer confusion. This ruling reinforces the protection afforded by common law passing off principles against calculated attempts to capitalize on established goodwill.
