properties of other ingredients is their use as fuel, the claimed invention would fall within Section 3(p). Indeed, a Google search is sufficient to establish the conventional use of cow dung as fuel, in combination with neem and lemon leaves (for fragrance and as insect repellents), and to make lamps during festivals, such as Diwali. In the claimed invention, the lamp is produced from the mixture of these components and, upon being lit, it has the effects of, inter alia , emitting light, acting as a mosquito repellent and not leaving a carbon footprint. The usage of such traditional knowledge, including by using known properties of the ingredients, therefore, falls within the exclusion in Section 3(k). For reasons set out above, I see no reason to depart from the conclusions of the second respondent on Section 3(p) of the Patents Act. This conclusion, on its own, is sufficient to reject this appeal. Nonetheless, since conclusions on other exclusions under Section 3 and on lack of inventive step were recorded in the impugned order, the same are also discussed.
