Executive Summary
The Delhi High Court dismissed Sun Pharma's appeal against the denial of an interim injunction concerning pharmaceutical trademarks. The court held that since both parties are generic drug manufacturers launching products after patent expiry, and given the similarity of the marks is based on active ingredients, there were no strong equities in favor of either party at this preliminary stage. Furthermore, the appellant's registered mark had not been used for over twenty-four years, which weighed against granting immediate protection.
