a monopoly with respect to the importation of the patented article. Thus it would presuppose that some efforts to manufacture in India should also be made by the patent holder. This is further supported by the other considerations set out in Section 83 of the Act to be applied in construing 'worked in territory of India'. Section 83(c) of the Act provides that there must be transfer of technological knowledge to the mutual advantage of the producers and users of the patented article. In this case, the user of the knowledge of the technology is the patient in India i.e. cancer patients. Section 83(f) of the Act provides that patent holder should not abuse his patent so as to inter alia adversely affect international trade. As against the above, Form 27 as prescribed also gives an indication that importation could also be a part of working in India. Therefore, as rightly held by the Tribunal, it would need to be decided on case-to-case basis. It would, therefore, follow that when a patent holder is faced with an application for Compulsory License, it is for the patent holder to show that the patented invention/ drug is worked in the territory of India by manufacture or otherwise. Manufacture in all cases may not be necessary to establish working in India as held by the Tribunal. However, the patent holder would nevertheless have to satisfy the authorities under the Act as to why the patented invention was not being manufactured in India keeping in view Section 83 of the Act. This could be for diverse reasons but it would be for the patent holder to establish those reasons which makes it impossible/ prohibitive for it to manufacture the patented drug in India. However, where a patent holder satisfies the authorities, the reason why the patented invention could not be manufactured in India then the patented invention can be considered as having been worked in the
