Justice Manmohan, however, gave liberty to Natco to seek the court's permission to export the drug as and when it gets the nod from the Drug Controlling Authority.
The court also issued notice to the Centre, customs authorities and Natco, seeking their replies on the plea of Bayer which has alleged that the generic drug is being made under compulsory licence for sale in India and thus, it cannot be exported.
Bayer in its plea has sought directions to the customs authorities to seize and confiscate the consignment containing Sorafenat manufactured by Natco Pharma Ltd under compulsory licence granted by the patent office on March 9, 2012.
The company, represented by senior advocate Mukul Rohatgi, has contended that the compulsory licence was granted with the condition that permission is being granted for making and selling the drug "within the territory of India".
Sorafenat is the generic alternative to Bayer's Nexavar, and is used to treat a type of kidney cancer called advanced renal cell carcinoma as well as liver cancer.
