Patent FER Reply and Hearing in India
Sections 12 to 15 and 21, Patents Act, 1970 · Patents Rules, 2003, as amended in 2024
A First Examination Report (FER) is the Indian Patent Office’s list of objections to a patent application, typically on novelty, inventive step, Section 3 exclusions, clarity of claims or formalities. The applicant has six months from the FER to meet every requirement, extendable by three months on Form 4 under the Patents Rules as amended in 2024; an application not put in order in time is deemed abandoned (Section 21). Objections that remain go to a hearing before the Controller.

What is a First Examination Report in a patent application?
The FER is the examiner’s report after a request for examination on Form 18 or 18A is taken up. It sets out every requirement the application must meet before grant: objections on patentability, on the claims and description, and on formal documents. It usually cites prior-art documents found in the examiner’s search.
The FER starts the most important deadline in Indian patent prosecution. Within six months, extendable by three, the applicant must put the application in order for grant by answering every objection, amending the specification where needed, and filing any missing documents. Silence, or a partial response, risks the application being treated as abandoned.
What objections does a patent FER usually raise?
| Objection | Basis | Typical response |
|---|---|---|
| Lack of novelty | Sections 2(1)(j) and 13 | Show a claimed feature missing from each cited document; amend claims to that feature if needed |
| Lack of inventive step | Section 2(1)(ja) | Explain the technical problem, why the solution was not obvious from the cited art, and any unexpected advantage |
| Not an invention | Section 3, for example 3(d), 3(k) | Show technical effect, or enhanced efficacy with data; recast claims around the technical contribution |
| Unclear or unsupported claims | Section 10(4) and 10(5) | Amend the claims for clarity and support in the description |
| Lack of unity | Section 10(5) | Restrict the claims, and file a divisional application for the rest if wanted (Section 16) |
| Foreign filing details | Section 8, Form 3 | File an updated Form 3 and documents from corresponding applications abroad |
| Formal requirements | Patents Rules | File the missing power of attorney, inventorship declaration, priority document or corrected drawings |
How do you reply to a patent FER?
Week 1
Analyse the report
List every objection, read each cited document in full, and confirm the six-month date and the latest date for an extension.
Weeks 2 to 6
Agree the strategy with you
Which objections to argue, which to meet by amendment, and whether new data or a divisional application is useful.
Weeks 4 to 10
Amend the specification
Amendments are limited to disclaimer, correction or explanation, and must stay within what was originally disclosed (Section 59).
Within 6 months
File the reply
A point-by-point response with amended claims and any supporting documents, filed online. Form 4 is filed if more time is needed.
After the reply
Hearing, if objections remain
The Controller issues a hearing notice. The hearing is usually by video conference, and the applicant may propose further amendments.
After the hearing
Written submissions and decision
Written submissions follow within the period the Rules allow, and the Controller grants the patent or issues a reasoned refusal.
What are the deadlines after a patent FER?
| Step | Time limit | Basis |
|---|---|---|
| Reply and put the application in order | 6 months from the FER | Patents Rules, 2003, as amended in 2024 |
| Extension of the reply period | Up to 3 months more, on Form 4 | Patents Rules, 2003, as amended in 2024 |
| Updated Form 3 on foreign applications | Within 3 months of the FER | Patents Rules, 2003, as amended in 2024 |
| Hearing | On the date in the hearing notice | Section 14 |
| Written submissions after hearing | Within the period set by the Rules | Patents Rules, 2003 |
| Appeal against refusal | To the High Court, within the period allowed | Section 117A |
A missed FER deadline is hard to repair
An application not put in order for grant within the time allowed is deemed abandoned under Section 21. Restoration provisions apply to granted patents that lapse, not to abandoned applications. Ask for the extension on Form 4 before the period runs out if you need it.
Where the FER sits in the patent journey
The FER follows the request for examination on Form 18. Each card gives the period the Patents Act and Rules fix; the full stages, with sections and sources, are on patent registration in India.

Periods checked on against the Patents Act, 1970 and the Patents Rules, 2003 as amended in 2024. Periods run from the priority date unless the stage says otherwise. Examination and grant times vary by field and office; only the periods marked statutory are fixed.
Which Patent Office handles your application?
Rule 4 of the Patents Rules, 2003 decides it, by where the applicant resides, is domiciled or has a place of business in India, or where the invention originated; applicants with none of these in India use their address for service in India. See patent registration in India.

Patent FER FAQs
How long do I have to reply to a patent FER in India?
Six months from the date of the FER, which can be extended by up to three months on Form 4. The Form 4 request must be made before the six months run out (rule 24B(6)). Rule 138 separately allows the Controller to extend periods under the Rules or condone delay by up to six months, but plan the reply for the six-month date.
Is a hearing always held before refusal?
The Controller must give the applicant an opportunity to be heard before refusing an application (Section 14). If the reply resolves every objection, the patent can be granted without a hearing.
Can I add new features to the claims when replying?
Only features already disclosed in the specification as filed. Amendments are limited to disclaimer, correction or explanation and cannot introduce new matter or claims outside the original scope (Section 59).
What if the FER cites an invention very close to mine?
We look for the technical difference and its effect. Often the claims can be narrowed to the feature that makes the difference, which still gives commercially useful protection.
Can I split my application after a unity objection?
Yes. A divisional application can be filed for the inventions removed from the claims, before grant (Section 16). It keeps the original priority date.
Can I speed up examination after filing?
If you are eligible, for example as a startup or small entity, you can request expedited examination on Form 18A. It must be filed online with the higher expedited fee.
What can I do if the Controller refuses my application?
You can appeal to the High Court under Section 117A, or in some cases ask the Controller to review the decision. Appeals are time-bound, so take advice as soon as the order is received.
