Delhi HC seeks response on Natco's patent challenge plea

The Delhi High Court is reviewing Natco Pharma's challenge to a breast cancer drug patent. Natco alleges Novartis and Astex secured two patents for the same invention. This action, Natco claims, unlawfully extends patent protection for the Ribociclib molecule. The court will first determine the petition's maintainability after legal arguments. The case has been scheduled for further hearing on September 16.
