Dispute Summary
In a complex trademark dispute, Sun Pharma sought permanent injunction against Hetero Healthcare regarding the alleged infringement of its mark 'LETROZ' by 'LETERO'. The court allowed the Defendants to challenge the validity of Sun Pharma's marks through a rectification petition under Section 57. Crucially, the court clarified that while invalidity can be challenged, the primary suit for passing off will proceed independently, leading to framing of multiple issues covering both infringement and validity.
