Responding to a Patent FER in India: 6 + 3 Months, Form 4, Form 3, Expedited Track

How-to · Patent Prosecution

Updated for 2026 · Claw Editorial

A First Examination Report (FER) starts a clock. If your reply and any needed documents are not in order before that clock ends, the application is treated as abandoned, and you may lose the patent. This guide explains, in plain steps, how to respond to a patent FER in India and how to track the deadline so it is never missed. Last verified October 2026.

01Why the FER deadline is risky

The First Examination Report is the Patent Office’s first list of objections to your application. It may raise lack of novelty, lack of inventive step, non-patentable subject matter under Section 3, unclear claims, or missing documents. Almost every application gets one.

The danger is not the objections. They are normal. The danger is the date. The report is issued on a date you do not control, it reaches you through the IP India portal or your agent, and the period to put the application in order starts from the date of the report, not from the day you read it.

• Many moving parts: the written reply, amended claims, a hearing request if you want one, and Form 3 updates may all fall due together.
• Many applications: a firm or an in-house team may hold dozens of files, each with its own report date.
• Late notice: a report can sit unseen in an inbox or a portal for weeks.

02The deadline: 6 months, plus up to 3 more

Under Rule 24B of the Patents Rules, 2003, you must put the application in order for grant within 6 months from the date the FER is issued. That means filing a reply that meets every objection, or otherwise bringing the application to a state where the Controller can grant it.

You can ask for more time. Under the 2024 amendment, you may extend the period by 3 months by filing Form 4 with the fee. That makes the outer limit 9 months from the date of the FER. Under the amended rules the extension request can be made even after the first 6 months have passed, but it must still fall inside the 9 month limit.

The 9 month limit is the hard edge. Treat month 6 as your real deadline and month 9 as an emergency.

03Step by step: how to respond to a patent FER

1. Note the date of the FER. Write down the issue date, then calculate month 6 and month 9. Put both in your calendar the same day.
2. Read every objection. List each one: novelty, inventive step, Section 3 grounds, clarity, unity of invention, formal defects.
3. Study the cited prior art. Read the documents the examiner cited. Decide for each whether you will argue, amend, or both.
4. Check Form 3. If you have foreign filings, bring the details up to date (see the Form 3 section below).
5. Prepare the reply. It usually has amended claims (clean and marked up), arguments on each objection, and any supporting evidence or declarations.
6. Decide on a hearing. If the objections stay unresolved after your reply, the Controller may call a hearing. You can also request one.
7. File online on the IP India portal, before month 6, or file Form 4 for the extension in time.
8. Diarise what comes next. Hearing notice dates, any further reply dates, and the grant or refusal order.

If your reply does not remove every objection, you may get a hearing notice, and a further reply may be due after it. Each of those has its own date. Keep every one of them on the same tracker.

04Form 4: extension of time and fees

Form 4 is the request for extension of time. Its fee depends on who files, and it is charged per month of extension asked for. Based on the IP India fee schedule as we last checked:

So a full 3 month extension costs Rs 3,000 or Rs 12,000 on these rates. Paper filing is charged at a higher rate.

Rule 138 is the general power of the Controller to extend time under the Rules, and it is also exercised through Form 4. It is wider than the FER extension. For a deeper look at how that power works, and its limits, see patent extension of time under Form 4 and Rule 138.

05Form 3 under Rule 12(2): do not forget it

Section 8 of the Patents Act requires you to keep the Controller informed of corresponding applications you file abroad. This is done on Form 3 (Statement and Undertaking).

Under Rule 12(2), you must give the Controller the details of other applications filed in any country within 3 months from the date of issue of the first statement of objections under Rule 24B (or 24C). In practice this means that the Form 3 update is due long before your FER reply deadline at month 6.

• The Controller can also ask for a fresh Form 3 under Section 8(2), with a separate time limit given in the request.
• Missing Section 8 information can lead to objection, and in serious cases it can be used against a granted patent.

Treat Form 3 as its own deadline: report date plus 3 months. Many teams track only month 6 and miss this one.

06The expedited examination track

Normally, examination starts only when a request is filed and the application reaches its turn in the queue. Rule 24C allows expedited examination on Form 18A, with fee, on listed grounds. Examples are when the applicant is a startup, a small entity, a woman applicant, a government department or an educational institution, or where India was chosen as the International Searching Authority.

Two points matter for deadlines:

• The expedited track gets you the FER sooner. It does not give you a longer reply period. The same 6 months plus 3 months limit applies to the FER.
• A faster FER means your Form 3 and reply dates come sooner too. Prepare your prior art and claims before you ask for speed.

07How to track the FER deadline so it is never missed

The reply itself is legal work. The deadline is a tracking problem. A simple system works:

1. One list for all files. Application number, FER date, month 3 (Form 3), month 6 (reply), month 9 (outer limit).
2. Early warnings. Set alerts at 30 and 14 days before each date, sent to more than one person.
3. Check the portal on a schedule. Do not rely on an email alone. Look at the IP India status for each file regularly.
4. Record each step done. When Form 3 is filed or Form 4 is filed, note the date and the acknowledgment.
5. Link related court matters. If the same patent is also in a revocation or infringement suit, those hearings need their own dates on the same calendar.

08Where Claw fits

Claw is an all-in-one legaltech platform for Indian advocates, law firms, and corporate legal teams, combining AI-based case search, an AI legal assistant (Legal GPT), case management, and compliance automation across all Indian courts and tribunals.

Answering an FER and tracking its deadline is registry work. If the same patent is later in a revocation or infringement suit, those hearings sit in the court record. Claw tracks cases, orders and hearings across 9,102 courts, benches and forums, with 30 crore+ judgments and results in under 5 seconds, covering the Supreme Court from 1950 and the High Courts from 1990. So you can keep the court side of a patent in view alongside the prosecution dates.

Claw does not use customer documents to train AI models. Create a FREE Claw account to follow patent litigation by party, number or advocate. To search the wider body of law, see case search across Indian courts.
