How to Register a Patent in India: The Complete Filing Process

A patent gives you a time-limited monopoly — up to 20 years — over an invention, in exchange for disclosing how it works. In India, the process is governed by the Patents Act, 1970, and it is more involved and more deadline-heavy than trademark registration. This guide walks through it end to end, in plain language.

First, is your invention patentable?

To be patentable in India, an invention must clear three tests: it must be novel (new to the world, not already disclosed anywhere), involve an inventive step (non-obvious to someone skilled in the field), and be capable of industrial application. Just as important is what the Act excludes under Section 3 — including, in most cases:

• A mere discovery of a scientific principle or an abstract theory.
• Mathematical or business methods, and computer programs 'per se'.
• A method of agriculture or horticulture.
• Methods of medical treatment of humans or animals.
• Mere admixtures or rearrangements of known things with no synergistic effect.

Step 1 — Run a patentability search

Before drafting, search existing patents and published literature (the 'prior art') to gauge whether your invention is genuinely new and non-obvious. A good search saves you from spending years and significant fees on an application that prior art was always going to block, and it sharpens your claims around what's actually inventive.

Step 2 — Provisional vs complete specification

India lets you file a provisional specification to lock in an early priority date while your invention is still being refined. You then have 12 months to file the complete specification with full claims. If the invention is already fully developed, you can file the complete specification directly.

• Provisional: secures a priority date early; buys 12 months to finalise. Miss that 12-month deadline and the application is treated as abandoned.
• Complete: the full disclosure plus the claims that define the legal scope of protection.

Step 3 — File the application

Applications are filed with the Indian Patent Office (online), with the specification, drawings, and the prescribed forms. Fees are tiered — individuals, startups, and small entities pay less than large entities. If you've filed abroad, watch the rules on foreign filing licences and timelines.

Step 4 — Publication

Applications are normally published in the Official Journal after 18 months from the priority date. You can request early publication to start your rights clock sooner. Publication is what puts the world on notice of your application.

Step 5 — Request for Examination (don't miss this)

Crucially, examination in India is not automatic. You must file a Request for Examination (RFE) within the prescribed period from the priority date. Miss it and the application is deemed withdrawn — one of the most common and most costly mistakes in Indian patent practice.

Step 6 — Examination and the FER

An examiner reviews the application and issues a First Examination Report (FER) raising objections — on novelty, inventive step, clarity, or Section 3 exclusions. You must put the application in order for grant within the statutory period (responding to the FER, often through amendments and arguments, and sometimes a hearing). This response window is a hard deadline.

Step 7 — Grant and annuities

Once objections are resolved, the patent is granted and published. A patent lasts 20 years from the filing date of the application — but only if you pay the annual renewal fees (annuities). Stop paying and the patent lapses, putting your invention in the public domain.

How long does it take?

Patents take years, not months — commonly several years from filing to grant, depending on examination backlogs and how many rounds of objections arise. Expedited examination is available in certain cases (for example, for startups). Across that long timeline sit multiple non-negotiable deadlines, which is where most applications quietly die.

The deadlines that sink patent applications

• Filing the complete specification within 12 months of a provisional.
• Filing the Request for Examination within the prescribed period.
• Responding to the FER and putting the application in order in time.
• Paying annuities every year to keep a granted patent alive.

Where software helps

Patenting rewards good drafting and good timekeeping in equal measure. An IP platform keeps every application, status, and statutory date in one place and reminds you well before each one — the RFE deadline, the FER response, every annuity. Novipra is built to docket exactly these dates for Indian IP practice, so a patent is never lost to a missed deadline.
