Madras High Court affirms rejection of IIT-M Patent on ‘Method of Doping Potassium’, for lack of inventive step
Madras High Court concluded that without any experimental data to compare the costs of using filtrate material, which requires frequent changing, vis-a-vis using an external reagent, the economic significance of the claimed invention cannot be established. Thus, the claimed invention lacks an inventive step under Section 2(1)(ja) of the Patents Act.
