The proviso to Section 84(6)(iv) says the requirement of prior efforts to obtain a licence "shall not be applicable in case of national emergency or other circumstances of extreme urgency or in case of public non-commercial use or on establishment of a ground of anti-competitive practices adopted by the patentee".
