Chapter II, Section 3 of the Indian Patents Act stipulates what is not considered an invention under the law and is therefore not patentable in India:
- inventions being frivolous or contrary to public order, morality, public health, the environment, etc.
- scientific discoveries
- mere discoveries of new forms of known substances
- methods of agriculture or horticulture
- diagnostic, therapeutic and surgical methods for the treatment of humans or animals
- plants and animals other than micro-organisms
- mathematical or business methods or computer programs per se or algorithms
- literary, dramatic, musical or artistic work or any other aesthetic creation
- schemes, rules or methods of performing mental acts or methods of playing games

Inventions relating to atomic energy are not patentable either.
