Section 2 of the Patents Act, 1970, define invention as a new product or process involving an inventive step and capable of industrial application. With the proposal of introduction of product patents, the definition is broadened by introduction of the words 'non-obvious' and 'useful' synonymous to inventive step and capable of industrial application, respectively. A patent is a form of intellectual property. A patent gives its owner the right to exclude others from making, using, selling, and importing an invention for a limited period of time, usually twenty years. The third amendment to the Patents Act 1970 was introduced through the Patents (Amendment) Ordinance, 2004 w.e.f. 1st January, 2005. This Ordinance was later replaced by the Patents (Amendment) Act 2005 (Act 15 Of 2005) on 4th April, 2005 which was brought into force from 1-1-2005.
