J.MITRA & CO.PVT.LTD. vs ASST.CONTROLLER OF PATENTS & DESIG.

The Supreme Court addressed the confusion arising from the postponed commencement of the Patents (Amendment) Act, 2005, particularly concerning the application of Sections 25 and 116 of the Indian Patents Act, 1970. The Court clarified that appeals against decisions made by the Controller regarding 'pre-grant oppositions' under Section 25 were maintainable before the High Court under Section 116(2) as it stood in 2000. The judgment emphasized the importance of clear legislative timelines and the implications of amendments on pending patent applications.
