Exclusive statutory rights for inventors, governed by The Patents Act, 1970 — protecting innovations for up to 20 years from the date of filing.
In India, a patent is a statutory right granted by the government to an inventor for a limited period, typically 20 years from the date of filing the patent application. This right is governed by The Patents Act, 1970, as amended.
The patent holder gains the exclusive right to prevent others from making, using, selling, or importing the patented invention without their permission — creating a powerful legal shield around your innovation and establishing a clear competitive advantage in the market.
The invention must be new and not previously disclosed to the public in any form, either in India or anywhere else in the world. Prior disclosure — in any medium — will disqualify an invention from patent protection.
The invention must involve a technical advancement over existing knowledge or have economic significance. Critically, it must not be obvious to a person skilled in the relevant field — it must represent a genuine leap beyond the known.
The invention must be capable of being made or used in an industry. This requirement ensures patents are granted only for practical inventions with real-world utility, not merely theoretical constructs.
The Patents Act explicitly lists exclusions designed to balance innovation with public welfare. The following inventions cannot be protected by a patent in India:
While India does not distinguish between "utility" and "design" patents as some jurisdictions do — design protection is governed separately under the Designs Act, 2000 — the Patents Act, 1970 covers both products and processes. Several application types are available:
A standard application filed without claiming priority from any earlier application — the most straightforward route for new inventions with no prior filing history.
Filed to secure an early filing date for an invention still under development. Gives the inventor a 12-month window to file a complete specification without losing priority.
The full and final document providing a detailed description of the invention and its claims. Must be filed within 12 months of a provisional application.
Filed in India within 12 months of a corresponding application in a convention country, allowing the applicant to claim the priority date of that earlier application.
Part of the Patent Cooperation Treaty process for filing in multiple countries simultaneously. The PCT National Phase application is the final step for a PCT application entering India.
Granted for an improvement or modification of an already applied-for or granted invention. It expires alongside the main patent, keeping related innovations protected under one umbrella.
