What Is a Patent? A Plain-English Guide for Indian Founders and Inventors

A patent is a government-granted right that stops others from making, using, selling or importing your invention without permission, for a fixed period — 20 years from the filing date in India. It does not protect an idea in the abstract. It protects a specific, clearly described technical solution to a technical problem.

To qualify, an invention must meet three tests under the Patents Act, 1970. It must be novel, meaning no one has publicly disclosed it anywhere in the world before you file. It must involve an inventive step, meaning the solution would not be obvious to someone skilled in that field. And it must be capable of industrial application, meaning it can actually be made or used in some industry.

Certain things are excluded from patent protection in India even if they are new. This includes discoveries of scientific principles, mathematical or business methods, mere schemes or rules for playing games, a method of agriculture, and software claimed purely as a computer program without a demonstrated technical effect. Founders building software products should note this last point carefully — a software-driven invention can often still be patented in India if the application is drafted around the technical problem it solves, not just the code.

One detail catches inventors off guard more than any other: public disclosure before filing can destroy novelty. Presenting your invention at a conference, publishing a paper, demoing it at a pitch event, or even discussing it in an unprotected conversation can count as prior disclosure. India does allow a narrow twelve-month grace period for disclosures made at certain recognised exhibitions, but the safer rule is simple — file first, talk later.

Who can apply. The true and first inventor can apply, and so can an assignee such as a company that the inventor has assigned rights to, which is the usual route for founders building inside a startup. Joint applications are common where multiple inventors or a company and an individual apply together.

The route most Indian founders take starts with a provisional application, a lower-cost filing that locks in a priority date while the invention is still being refined. A complete specification, with full technical detail and legal claims, must follow within twelve months. From there, the application is published, examination is requested, the patent office raises objections in an examination report, the applicant responds, and — if the office is satisfied — the patent is granted. The full process commonly takes two to five years, though India's patent office has been working to speed this up for startups and MSMEs, who also qualify for reduced official fees.

A patent is only as strong as its claims. The claims define the legal boundary of what is protected, and a narrow or poorly drafted claim can leave real gaps for a competitor to design around. This is the single biggest reason patent drafting is not a do-it-yourself exercise: the description can be technically accurate and still fail to protect the commercially important part of the invention if the claims are written loosely.

Founders often ask whether to patent early or wait until the product is more finished. The honest answer depends on disclosure risk and competitive pressure. If you are about to demo publicly, raise funds with a detailed pitch, or you know close competitors are working on similar problems, filing a provisional application early protects your priority date without requiring a finished product. If the invention is still changing significantly, filing too early can mean the eventual complete specification no longer matches what you actually built.

At Ragulika IP, we work with founders, researchers and R&D teams from the earliest concept stage — running a novelty search before you spend on drafting, identifying what is genuinely patentable versus what should be protected as a trade secret instead, and drafting claims built to withstand examination and, later, litigation. If you are weighing whether your invention is ready to file, talk to our team before your next public disclosure, not after.
