M/S A & J Designers successfully challenged the non-renewal of their 'Paris' trademark registration in the Kerala High Court.

Yamaha Hatsudoki Kabushiki Kaisha v.Mr. Devender Kumar And Anr.
The Calcutta High Court allowed an appeal filed by Yamaha Hatsudoki Kabushiki Kaisha against a rejection of its trademark application for 'R3' in Class 12. The court found that the original rejection failed to consider key arguments, including the appellant's claim that R3 was an associated mark and their existing portfolio of related marks (like YZF-R3). Consequently, the High Court set aside the impugned order and remanded the matter back to the Controller for a fresh hearing.
Ds Drinks And Beverages Private Limited v.Hector Beverages Private Limited
The Delhi High Court dismissed the appeal filed by Ds Drinks And Beverages Private Limited, upholding the interim injunction granted to Hector Beverages Private Limited.

Given that both products are allied and sold across the same counter, the court ruled that there is a clear likelihood of customer confusion, favoring the established goodwill of Hector Beverages.
