Patents Act, 1970
83. General principles applicable to working of patented inventions
Without prejudice to the other provisions contained in this Act, in exercising the powers conferred by this Chapter regard shall be had to the following general considerations, namely,-
(a) that patents are granted to encourage inventions and to secure that the inventions are worked in India on a commercial scale and to the fullest extent that is reasonably practicable without undue delay; and
(b) that they are not granted merely to enable patentees to enjoy a monopoly for the importation of the patented article.
