What makes an invention patentable in India under the Patents Act

Question

I have developed a new technical process and want to know whether it qualifies for a patent under Indian law. Before I spend money on it, I want to know whether Patents Act, 1970, Section 2(1)(j) gives me a remedy here and what proof I would need. Any Section numbers I can quote when I write to them would be useful.

Patents Act, 1970, Section 2(1)(j) and Patents Act, 1970, Section 3 is what decides this question in India. Read it alongside the provisions named, because the relief available to you turns on the facts you can prove on paper.

Section 2(1)(j) of the Patents Act, 1970 defines a patentable invention as a new product or process involving an inventive step and capable of industrial application, meaning the invention must be novel, non-obvious to a person skilled in the art, and usable in industry.

Section 3 lists categories that are not inventions for the purposes of the Act even if they otherwise appear novel, including frivolous inventions, discoveries of a scientific principle or abstract theory, mere admixtures resulting only in aggregation of properties, methods of agriculture or horticulture, and methods of treatment of human beings.

Section 3(k) specifically excludes mathematical or business methods, computer programmes per se, and algorithms from patentability, which is the most litigated exclusion for software-related inventions, though inventions demonstrating a technical effect beyond the computer programme itself have succeeded before the Patent Office and courts.

Novelty is assessed against 'prior art' anywhere in the world as of the priority date, so public disclosure, prior sale, or even the inventor's own publication before filing can destroy novelty, subject to the narrow grace period under Section 31 for disclosure at certain exhibitions or before learned societies.

In practice, in this order: 1) Conduct a prior art search before public disclosure or filing; 2) Avoid publishing or publicly demonstrating the invention before filing a patent application; 3) Check whether the invention falls within any Section 3 exclusion; 4) File a provisional or complete specification promptly to secure the priority date.

Timing matters here: Patents Act, 1970, Section 2(1)(j) works on limitation periods, so a patentability india claim that is right on the merits can still fail if it is brought late.
