Case Note & Summary
The dispute arose from the patent application filed by J. Mitra & Co. Pvt. Ltd. in 2000, which was opposed by Span Diagnostics Limited. The Patents (Amendment) Act, 2005 introduced a dichotomy in patent law, distinguishing between pre-grant and post-grant opposition. The appellant argued that the respondent's appeal against the rejection of its pre-grant opposition was not maintainable due to the changes in the law. The respondent contended that its appeal was valid under the law as it stood at the time of filing. The court analyzed the legislative intent behind the amendments and the timing of their enforcement. It concluded that the appeals filed by the respondent were valid as they were made under the old law before the new provisions came into force. The court directed that the High Court should hear and decide the appeals in accordance with the law as it stood prior to the amendments, thereby allowing the respondent to seek remedy for its grievances. The two civil appeals were disposed of with no order as to costs.
