What Inventions Are NOT Patentable in India?
(Understanding on Section 3 of the Indian Patents Act)
Continuing our 𝐊𝐧𝐨𝐰𝐥𝐞𝐝𝐠𝐞 𝐁𝐚𝐬𝐞 𝐏𝐚𝐭𝐞𝐧𝐭 𝐒𝐞𝐫𝐢𝐞𝐬, a practical guide for inventors, startups, and researchers to better understand patent protection in India.
When inventors apply for patents in India, it’s important to know that not all inventions qualify for patent protection. The Indian Patents Act sets some clear rules about what cannot be patented, mainly in under Sections 3 to 5. Let’s understand these rules in simple terms.
Section 3: What Cannot Be Patented?
Key points to note under Section 3: types of inventions excluded from patentability include:
Scientific theories and mathematical formulas: Pure ideas or discoveries without practical application can’t be patented. There should be some method or system with technical effect need to claim for Patent.
Discoveries of naturally occurring substances: Just finding a plant, mineral, or micro-organism in nature isn’t patentable.
Business methods and mental acts: Pure business plans, algorithms, or ways of playing games are excluded unless they produce a technical effect.
Medical treatments and surgical methods: Methods of treating humans or animals (like surgeries or therapies) are not patentable, only formulations and compositions can be patented.
Mere arrangement, re-arrangement, or duplication of known devices: Items that are merely aggregated without creating a new functional result are excluded are not patentable.
Literary, artistic works, or aesthetic creations: Inventors needs to understand that these can be protected under copyright, not patents.
Agricultural methods: Traditional farming or gardening methods are excluded.
Computer programs ‘per se’: Software alone can’t be patented unless tied to technical hardware or effect.
