An Act section is not a Rule. Knowing which one you are reading changes the answer.
Almost every avoidable mistake in an Indian patent matter starts with confusing the two. This site keeps them in separate collections, with separate URLs, separate badges and separate indexes — and links them where they work together.
The Act gives you the right
Passed by Parliament. It decides what counts as an invention, who may apply, what a patent lets you stop, when a patent can be revoked, and what powers the Controller and the courts have.
- Section 3 — what is not an invention
- Section 48 — the rights a patentee gets
- Section 64 — how a patent is revoked
The Rules tell you how, on what form, by when
Made by the Central Government under the Act. They prescribe the forms, the fees, the time limits and the office procedure. Change a rule and the paperwork changes; the underlying right does not.
- Rule 24B — requesting examination
- Rule 55 — pre-grant opposition procedure
- Rule 138 — extending time and condoning delay
The questions Indian inventors actually search for
Each hub gathers the sections, rules, forms and deadlines that belong to one stage of the patent journey, so you are not jumping between unrelated provisions.
What can and cannot be patented
Section 3 is where most Indian applications get stuck. Learn the exclusions before you spend on drafting.
Filing a patent application
Provisional or complete, who may apply, what Form 1 asks and what the priority date really buys you.
Examination and the FER
The request for examination, the first examination report and the clock that starts the moment it issues.
Pre-grant and post-grant opposition
Two very different routes, two very different windows, two very different sets of consequences.
Grant and the rights it gives
What a granted Indian patent actually lets you stop, and for how long.
Renewal, lapse and restoration
Miss a renewal and the patent lapses. There is a way back, but it is time-barred.
Foreign filing and secrecy
Why an Indian resident cannot simply file abroad first, and what Form 25 is for.
Working statements and compulsory licences
Form 27, the three-year rule, and how a competitor can ask for a licence over your head.
From idea to granted patent, and what the law says at each step
File
Provisional or complete specification, applicant category, Form 1 and Form 2. The filing date fixes your priority.
Publish
Ordinarily 18 months from the priority date, unless you ask for early publication. Publication starts a limited set of rights.
Examine
Nothing happens until you request examination. Then the FER arrives and a hard clock starts running.
Grant & maintain
Grant, the 20-year term from filing, renewal fees, working statements, and what happens if a renewal is missed.

Patent Rule 24CExpedited examination of applications

The three questions a patent examiner will ask
Indian law does not ask whether an idea is clever. It asks three narrower questions, and then checks the invention against a list of things the Act says are not inventions at all.
Is it new?
Novelty. If the invention was already published, used or displayed anywhere in the world before your priority date, it is anticipated. Your own pre-filing disclosure counts against you.
Is it non-obvious?
Inventive step. A skilled person in the field, knowing everything already published, must not have found the step obvious. Technical advance or economic significance matters here.
Can it be made or used?
Industrial application. And separately: is it excluded by Section 3? Business methods, algorithms as such, mathematical methods and mere discoveries do not qualify however good they are.
The pages people actually need at 11pm
Statute pages answer “what does this say”. These answer “what do I do now”.
What happens if…
Missed the examination request, no reply to the FER, a lapsed renewal, filed abroad without permission. Honest answers, including when there is no way back.

Get told when the Act or the Rules change
The Patents Rules were last amended in March 2024. Appeals moved to the High Courts in 2021. Several offences were decriminalised in 2023. When something changes, we update the affected pages and note it in the change log — and we can tell you.
