Patent Registration in India — Filing, Examination and Grant
A patent is a twenty-year monopoly, counted from the date of filing, granted in exchange for a full public disclosure of how your invention works. Under the Patents Act, 1970 an invention must be new, must involve an inventive step, and must be capable of industrial application — and it must not fall into one of the exclusions in section 3, which is where a great many Indian applications actually fail.
The process has more moving parts than any other Indian IP filing. You file Form 1 with a specification on Form 2, choose between a provisional and a complete specification, publish at eighteen months or earlier on request, file a separate request for examination that does not happen automatically, answer a First Examination Report within the period allowed, and then pay renewal fees from the third year to keep the patent alive for its full term.
This guide covers what is and is not patentable in India, provisional versus complete specifications, the forms and offices involved, indicative fees with the concessions for natural persons, startups, small entities and educational institutions, the expedited examination route under Rule 24C, pre-grant and post-grant opposition, renewal, and the working statement obligation that patentees most often forget.

What is a patent and what does registration give you?
A patent is an exclusive right granted for an invention — a product or a process that is new, involves an inventive step, and is capable of industrial application. Once granted, the patentee can prevent others from making, using, selling, offering for sale or importing the patented invention in India without licence, for the balance of the twenty-year term.
The bargain is disclosure. The complete specification must describe the invention fully, disclose the best method of performing it known to the applicant, and end with claims that define the scope of protection. Everything you disclose becomes public at publication, whether or not the patent is eventually granted.
Because of that, patents are the wrong tool for know-how you can keep secret and the right tool for something a competitor will reverse-engineer from the product itself. For appearance rather than function, use design registration instead.
What cannot be patented in India?
Section 3 lists what are not inventions within the meaning of the Act. It is a longer and stricter list than in many jurisdictions, and the exclusions are absolute — no amount of novelty rescues subject matter that falls inside them.
- 1.Frivolous inventions and anything contrary to well-established natural laws
- 2.Inventions whose primary or intended use would be contrary to public order, morality, or seriously prejudicial to human, animal or plant life, health or the environment
- 3.The mere discovery of a scientific principle or formulation of an abstract theory
- 4.The mere discovery of a new form of a known substance that does not enhance known efficacy
- 5.A substance obtained by mere admixture resulting only in aggregation of properties
- 6.The mere arrangement, rearrangement or duplication of known devices working independently
- 7.Methods of agriculture or horticulture
- 8.Methods of treatment of humans or animals, including diagnostic and therapeutic methods
- 9.Plants and animals in whole or any part thereof, other than micro-organisms
- 10.A mathematical or business method, a computer programme per se, or an algorithm
- 11.Literary, dramatic, musical or artistic works and cinematographic works — these are copyright subject matter
- 12.A mere scheme, rule or method of performing a mental act, or a method of playing a game
- 13.Presentation of information
- 14.Topography of integrated circuits
- 15.Inventions that are in effect traditional knowledge, or aggregation of known properties of traditionally known components
Software is the exclusion that causes the most difficulty. Section 3(k) bars a computer programme per se, and Indian courts have applied a technical effect test — a claim is not excluded merely because software is involved, but the invention must produce a technical effect or advancement and the claims must recite the hardware integers that make it work. Pure business methods remain excluded regardless of technical implementation.
Should you file a provisional or a complete specification?
A provisional specification secures an early priority date when the invention is developed enough to describe but not yet finalised. It is filed on Form 1 with Form 2 and does not need claims. You then have a fixed twelve months to file the complete specification, and that period is not extendable — miss it and the application is treated as abandoned and the priority date is lost.
A complete specification is filed where the invention is settled. It must fully describe the invention and its operation, disclose the best method known to the applicant, and conclude with claims and an abstract. Convention applications and PCT national phase applications cannot be filed with a provisional specification.
The practical rule is that a provisional buys you time to test, refine and raise money without losing the date — but only if the disclosure in it actually supports the claims you later make. A thin provisional that does not support the complete specification gives you a date you cannot rely on.
How does a patent compare with the other IP rights for a new product?
A hardware product typically needs more than one right. What distinguishes the patent is the cost and the examination burden — it is the most expensive and slowest of the four, and the only one that requires you to teach the public how to make the thing.
| Right | Test applied | Examination | Term | Upkeep |
|---|---|---|---|---|
| Patent | Novelty, inventive step, industrial application, not excluded by section 3 | Substantive, on request only | 20 years from filing | Renewal fees from the third year |
| Registered design | New or original, significantly distinguishable, judged by the eye | Formal plus novelty citation | 10 years, extendable by 5 | One extension fee |
| Trade mark | Distinctiveness, no conflict with earlier marks | Examination plus publication and opposition | 10 years per term | Renewal every 10 years, indefinitely |
| Copyright | Originality of expression | Formality check only | Generally life plus 60 years | None |
Sequencing matters more than choosing. A patent application must be on file before the invention is disclosed, and a design application before the product is shown. Brand filings can come later without losing rights, though earlier is safer — see trademark registration.
Who can apply for a patent in India?
An application may be made by the true and first inventor, by an assignee of the inventor, or by the legal representative of a deceased person who was entitled to apply. The applicant may be a natural person or a legal person such as a company, small entity, startup, research organisation, educational institution or the Government.
Where the inventor is not the applicant, proof of right to apply must be filed — either by endorsement in the appropriate paragraph of Form 1 or by a duly authenticated assignment from the inventors, generally within six months of filing the application in India. This applies to convention and national phase applications as well.
Applicant category drives both fees and eligibility for expedited examination. Startups need DPIIT recognition under Startup India; small entities are evidenced by MSME or Udyam registration. Form 28 with the appropriate evidence must accompany every document for which a concessional fee is claimed.
What documents and forms are needed for a patent application?
- Form 1 — application for grant of patent, with inventor and applicant particulars
- Form 2 — provisional or complete specification, with claims and abstract where complete
- Drawings where they help explain the invention, prepared to the prescribed standard
- Form 3 — statement and undertaking regarding corresponding foreign applications
- Form 5 — declaration as to inventorship, filed with the complete specification
- Form 26 — power of attorney where a patent agent acts for you
- Form 28 — claiming small entity, startup or educational institution status, with evidence
- Proof of right to apply where the applicant is not the inventor
- Priority documents and verified translations for convention applications
- Sequence listings in the prescribed electronic format for biotechnology inventions
- Form 9 — request for early publication, where you want to publish before eighteen months
- Form 18 or Form 18A — request for ordinary or expedited examination
A patent application is drafted, not filled in. The specification and claims determine what you actually own, and a specification that reads like a product brochure typically yields claims too narrow to stop anyone. Filing is electronic and signed with a digital signature certificate.
How to file a patent in India step by step?
- 1.Run a patentability and prior art search, including a section 3 screen for the excluded categories
- 2.Decide the filing route — provisional first, or straight to a complete specification
- 3.Draft the specification with a full description, the best method known, and claims of layered scope
- 4.File Form 1 with Form 2 and drawings, and pay the fee for your applicant category
- 5.File Form 3 on foreign filing particulars and keep it updated as foreign filings progress
- 6.Where a provisional was filed, file the complete specification within the non-extendable twelve months
- 7.File Form 5 declaration as to inventorship with the complete specification
- 8.Optionally file Form 9 for early publication instead of waiting for automatic publication at eighteen months
- 9.File the request for examination — Form 18, or Form 18A for the expedited route if eligible
- 10.Receive and analyse the First Examination Report with its objections on novelty, inventive step and section 3
- 11.File a reply with amended claims and submissions, and attend a hearing if one is offered
- 12.Deal with any pre-grant representation filed by a third party
- 13.On grant, receive the patent certificate and the patent number
- 14.Pay renewal fees from the third year onwards and file the statement of working when due
Note the two independent traps in that sequence. Publication is automatic but examination is not — no request for examination and the application is deemed withdrawn. And the twelve-month provisional-to-complete window has no extension mechanism at all.
How much does patent registration cost in India?
Official fees are set in the First Schedule to the Patents Rules and are tiered between the concessional category — natural persons, startups, small entities and educational institutions — and other applicants. The figures below reflect the current e-filing schedule and are indicative; physical filing attracts a surcharge over the e-filing rate. We confirm every figure against the schedule before filing.
| Stage | Form | Concessional category (indicative) | Other applicants (indicative) |
|---|---|---|---|
| Application for patent with specification | Form 1 and Form 2 | ₹1,600 | ₹8,000 |
| Excess sheets and excess claims | — | Per sheet and per claim above the base limits | Per sheet and per claim above the base limits |
| Early publication | Form 9 | Lower slab | Higher slab |
| Ordinary request for examination | Form 18 | ₹4,000 | ₹20,000 |
| Expedited examination | Form 18A | ₹8,000 | ₹60,000 |
| Conversion from ordinary to expedited | Form 18A | Differential fee | Differential fee |
| Pre-grant opposition representation | — | Lower slab | Higher slab |
| Renewal fees | — | Payable from the third year, rising with the year of the term | Payable from the third year, rising with the year of the term |
| Professional and drafting fees | — | Scoped after a short discovery call | Scoped after a short discovery call |
For most applicants the government fee is the smaller number. Specification drafting, claim strategy, examination replies and foreign filings are where the real budget goes, and under-investing in drafting is the most expensive saving available in patent practice.
What is expedited examination under Rule 24C?
Ordinary examination can take years because the request only enters a long queue. Rule 24C lets eligible applicants file Form 18A to place the application in a priority queue, with the First Examination Report issuing far sooner and grant timelines commonly quoted in the range of one to two years rather than three to five.
- The applicant is a startup recognised by DPIIT, with recognition valid on the date of filing the request
- The applicant is a small entity under the MSME Act
- All applicants are natural persons and at least one is female
- The applicant is a department of Government
- The applicant is an institution established by a Central, Provincial or State Act and owned or controlled by Government
- The applicant is a Government company as defined in the Companies Act, 2013
- The applicant is an institution wholly or substantially financed by Government
- The application pertains to a sector notified by the Central Government following a departmental request
- The applicant is eligible under an arrangement between the Indian Patent Office and a foreign patent office, such as a Patent Prosecution Highway programme
- India was chosen as the International Searching Authority or International Preliminary Examining Authority in the corresponding PCT application
A request for examination already filed on Form 18 can be converted to the expedited route on payment of the differential fee and filing the required documents. Note that expedited examination must be accompanied by a publication request unless the application has already been published. The trade mark system has its own accelerated route — see expedited trademark registration.
How long does it take to get a patent in India?
There is no fixed statutory timeline to grant. Publication happens automatically at eighteen months from the priority date, or within about a month of a Form 9 early publication request. Examination starts only after the request is filed, and for applications filed on or after the 2024 rules change the request for examination is due within thirty-one months of the priority date.
On the ordinary route, applicants commonly experience three to five years from filing to grant. On the expedited route, the First Examination Report arrives within months and grant within roughly one to two years is realistic where the objections are answerable. Neither is a promise — the timetable depends on the examiner’s objections, the quality of your reply and any opposition.
What is pre-grant and post-grant opposition?
Section 25(1) allows any person, after publication but before grant, to represent by way of opposition on the statutory grounds — wrongful obtaining, prior publication, prior claiming, prior public knowledge or use, obviousness, non-patentability, insufficiency of description, non-disclosure or wrong mention of source of biological material, and anticipation by traditional knowledge, among others. The opponent may request a hearing.
Section 25(2) allows any person interested, at any time after grant but before one year from the date of publication of the grant, to give notice of opposition on substantially the same grounds. Post-grant opposition goes to an Opposition Board and is a substantive proceeding rather than a representation.
Both routes are also a strategic tool if a competitor’s patent blocks you. Watching publications in your field is part of the same discipline as watching trade mark journals — see trademark protection for how that monitoring habit is built.
How do you keep a granted patent alive?
- 1.Pay renewal fees from the third year of the term, in advance of the due date
- 2.Note that fees escalate with the year of the term, so later years cost materially more
- 3.Consider paying several years in advance electronically where a discount is offered for doing so
- 4.File the statement of working of the patented invention on the prescribed form within the period allowed
- 5.Keep the Controller informed of changes in applicant name, address and address for service
- 6.Record assignments and licences so the register reflects the true proprietor
- 7.Track corresponding foreign applications and keep Form 3 particulars updated while the application is pending
- 8.Diarise every renewal date centrally, because a lapse requires restoration rather than a simple late payment
Following the 2024 rules amendments, the statement of working is filed once every three financial years rather than annually. It is a genuine statutory obligation and non-compliance is penalised, so it belongs on the compliance calendar next to your annual filings.
How do you protect an invention outside India?
Patents are territorial. An Indian patent is enforceable only in India. The usual route is to file in India first, then use the twelve-month Paris Convention priority period to file abroad directly, or to file a PCT international application that preserves the date while you decide which national phases are worth the money.
Indian residents must also observe the foreign filing licence requirement before filing abroad in the circumstances the Act specifies. If your commercial markets are overseas, plan the foreign programme at the same time as the Indian filing rather than after grant — see USA trademark registration for the parallel brand-side discussion.
Is a patent worth it for your business?
A patent is worth filing when the invention is genuinely novel, when a competitor could copy it from the product, and when you would realistically spend money enforcing it. It is worth much less when the advantage lies in execution, data, distribution or brand — all of which are protected by other means at a fraction of the cost.
Investors treat a granted patent as a durable asset and a pending application as a signal of technical depth, which is a real if secondary benefit. But the honest test is the enforcement one: a patent you would never litigate is a disclosure you did not have to make.
