• Exclusions: Ensure that your invention does not fall under the categories of non-patentable inventions as outlined in Section 3 and Section 4 of the Patents Act, 1970. These include, but are not limited to, inventions that are contrary to public order or morality, mere discoveries of scientific principles, or methods of agriculture and horticulture.
