First Examination Report in India: Structure, Objections and How to Respond (2025)

The First Examination Report is the Indian Patent Office’s formal examination output under Section 14 of the Patents Act, 1970, setting out every objection to grant, the prior art cited, and the statutory deadline for the applicant’s response.

Receiving the First Examination Report is the most consequential moment in Indian patent prosecution after filing. The report identifies every objection the Indian Patent Office has to grant, sets out the prior art cited, and starts a strict statutory clock.

Many applicants misread the examination report as a rejection. It is not. It is an invitation to argue, to amend, and to put the application in order for grant. Handled correctly, a well-structured FER response India applicants file under Rule 24B resolves all objections without a hearing. Handled incorrectly, by leaving objections unaddressed, introducing new matter, or missing the FER deadline India practitioners treat as absolute, it results in irreversible loss of the application.

This guide covers the complete examination process under the Patents Act, 1970 and Patents Rules, 2003 as amended by the Patents (Amendment) Rules, 2024. For the examination lifecycle leading up to report issuance, see: Patent Examination in India: Procedure, Timelines and Key Deadlines (2025).

Practical timelines reflect current IPO conditions and may vary. Statutory deadlines are fixed.

What Triggers the First Examination Report in India

The examination report does not issue automatically. Under Section 14 of the Patents Act, 1970 (Indian Patent Office official portal), the Controller issues it only after four conditions are met. First, a valid Request for Examination (RFE) has been filed on Form 18 or Form 18A. Second, the Controller has assigned the application to an examiner under Section 12. Third, the examiner has completed the prior art investigation under Section 13. Fourth, the Controller has reviewed that examiner’s report.

Under the Patents (Amendment) Rules, 2024, the report must issue within 1 month of the Controller receiving the examiner’s findings (Rule 24B(3)). The practical gap between RFE and report issuance is substantially longer: 12 to 24 months or more on the ordinary route; 1 to 3 months on the expedited route under Rule 24C. For expedited examination eligibility, see: Expedited Patent Examination in India (Rule 24C).

Practical Note A successful response and grant do not close the door to challenge. The patent can still be the subject of patent opposition proceedings in India before grant (Section 25(1)), after grant (Section 25(2)), or revocation proceedings. Build the strongest possible prosecution record from the first response onwards.

The Four-Part Structure of the FER

Part 1: Summary Checklist

Nine criteria must be satisfied for grant. Every criterion marked adverse must be addressed in the response. One unanswered finding is enough to prevent grant. The nine criteria are: novelty (Section 2(1)(l)); inventive step (Section 2(1)(ja)); industrial applicability (Section 2(1)(ac)); non-patentability under Section 3; non-patentability under Section 4; unity of invention (Section 10(5)); sufficiency of disclosure (Section 10(4)(a)(b)); clarity and support of claims (Section 10(4)(c)); and reference to foreign applications (Section 8).

Part 2: Detailed Technical Report

Part 2 contains the list of cited prior art (D1, D2, D3…) and the examiner’s detailed observations on each adverse finding. Every citation is linked by code to the claims it is cited against. The response must engage each citation by its code. Do not rely on the examiner’s characterisation: retrieve and read the full text of every cited document before drafting any argument or amendment.

Parts 3 and 4: Formal Requirements and Documents on Record

Part 3 lists formal compliance issues (pending forms, fee shortfalls, specification and drawing corrections). No argument is available; every item requires full compliance. Part 4 lists all documents on file and states the last date for filing the response. Record the issue date from Part 4 immediately and calculate both the 6-month and 9-month deadlines from that date.

Types of Patent Objections in the Indian FER

Indian patent objections in the examination report fall across seven categories. The response approach differs significantly between each: novelty and inventive step require distinct arguments; Section 3 objections require specialist handling; formal objections require compliance, not argument.

Novelty Objections (Section 2(1)(l))

A combination of documents cannot ground a novelty objection. The examiner must identify a single document disclosing each and every feature of the claim. The response requires either a technical argument that the cited document does not disclose one or more claim features, or an amendment narrowing the claim to include a feature absent from that document. Any such amendment must be supported by the original specification. For the novelty standard under Indian patent law, see: Novelty under Indian Patent Law: Section 2(1)(l) and Prior Art Standards.

Inventive Step Objections (Section 2(1)(ja))

Under Section 2(1)(ja), the examiner may combine multiple prior art documents to argue obviousness. The response must establish that the technical advance is non-obvious, that the proposed combination would not have been made by a person skilled in the art, or that the combination still does not arrive at the claimed invention. For inventive step analysis under Indian patent law, see: Inventive Step in Indian Patents.

Section 3 Non-Patentability Objections

Section 3 objections require a fundamentally different approach from prior art responses. The sub-clauses most commonly raised are 3(b), 3(d), 3(e), and 3(k). Dedicated response guides for Section 3(d) and Section 3(k) are in preparation. For the complete list of exclusions, see: What Cannot Be Patented in India: Section 3 Exclusions Explained.

How to Read an Indian FER: Triage Before You Draft

Work through these steps before drafting a single argument. A structured triage is the foundation of every successful FER response India practitioners file.

1. Record the issue date and calculate all deadlines: 6-month initial, 9-month outer, and 3-month Form 3 deadline. Diarise all three immediately.
2. Read the Summary Checklist: List every adverse criterion. Every one must be resolved.
3. Separate formal from substantive: Part 3 requires compliance; Part 2 requires technical argument and possibly amendments. Handle each independently.
4. Retrieve and read all cited prior art in full: Do not rely on the examiner’s summary. Build a citation-to-claim map before writing a single argument.
5. Assess amendment options under Section 59: For each claim under objection, identify whether a limiting amendment exists in the original specification. Flag complex objections for hearing consideration now, not after an unsuccessful response.

Drafting the FER Response: Structure and Requirements

The response is a formal legal document filed on the InPASS portal. It must cover every objection and put the application in order for grant within the 9-month window. Track the application and confirm filing dates on InPASS: How to Check Indian Patent Application Status on InPASS.

Structure of the Response

A complete response contains three components. First, written arguments addressing each substantive objection by citation code (D1, D2…). Second, amended claims filed on Form 13 with a claim amendment chart showing the specification basis for each change, where amendments are required. Third, full compliance with every Part 3 formal objection.

Written Arguments

Arguments must engage directly with the examiner’s reasoning in Part 2. For novelty: identify the specific claim feature absent from the cited document and reference the relevant passage. For inventive step: establish that the technical advance is non-obvious, that the combination would not have been made by a person skilled in the art, or that the combination does not arrive at the claimed invention. In practice, economic significance arguments under Section 2(1)(ja) are most effective when combined with technical advance arguments. Arguments and amendments combined are typically more persuasive than either alone.

Claim Amendments Under Section 59

Section 59 permits amendments only by way of disclaimer, correction, or explanation. Every proposed amendment must be traceable to specific language in the original specification. The key constraints:

Practical Note In practice, the Controller applies the new matter bar under Section 59 strictly at both examination and opposition stages. Pre-grant amendments are assessed more flexibly than post-grant, but any amendment introducing a feature without clear textual support in the original specification will be refused. Every proposed amendment must survive the question: is there verbatim or clearly equivalent support in the original specification text?

Formal Objections and the Form 3 FER Trigger

Every Part 3 formal objection requires full compliance. No argument is available. The most critical recurring issue is the Form 3 obligation triggered by examination: under Section 8(1) read with Rule 12(2) as amended 2024, an updated Form 3 is due within 3 months of the report date. This is extendable by 3 months under Rule 12(5) on a Form 4 request. This deadline runs independently of the response deadline and must be diarised separately. For the Section 8 disclosure framework, see: Statement and Undertaking Under Section 8 of the Patents Act.

The FER Response Window: Deadlines and Extensions

• Initial deadline: 6 months from the report issue date (Rule 24B(5)). This is the target, not the fallback. Every FER deadline India applicants face under Rule 24B(5) is calculated from this date.
• Maximum outer deadline: 9 months from the issue date. A 3-month extension is available by filing Form 4 under Rule 24B(6) at any time before expiry of the 3-month extension period itself. These deadlines apply under the Patents (Amendment) Rules, 2024, effective 15 March 2024.

WARNING: No remedy after 9 months Rules 24B(5) and (6) are expressly excluded from Rule 137(2) condonation under the Patents (Amendment) Rules, 2024. If no complete response is filed within 9 months of the report date, the application is at risk of abandonment with no retrospective remedy. Verify current rule text at the Indian Patent Office official portal. The Form 4 extension under Rule 24B(6) is a prospective power. It must be requested before the 3-month extension period itself expires. Once the 9-month window closes, no remedy exists. File within the 6-month initial window. Use the extension period only where complex objections require it, not as default practice.

The Subsequent Examination Report (SER)

An SER may issue if outstanding objections remain after the written response. It is not a separate examination. It continues the same 9-month cycle from the original report date. The SER does not reset the response clock. A late examination response may leave only days before the outer deadline closes. File within the 6-month initial window as default practice.

Practical Note In practice, an SER is more common where the initial response makes substantive amendments without full written arguments, or where arguments address only some of the cited prior art. Address every citation in the first response.

Requesting a Hearing on Your Indian FER

A hearing under Section 14 is most useful where substantive objections involve complex technical or legal arguments, Section 3 objections have been raised, or an SER indicates key objections remain unresolved after the written response. A hearing is not automatic. The applicant must request it within the response window. The Controller must give at least 10 days’ notice (Rule 129). Written submissions must be filed within 15 days of the hearing date. Hearings may be conducted by video conference on request, which is particularly relevant for foreign applicants.

WARNING: Non-attendance Non-attendance at a scheduled hearing without advance notice of postponement can result in refusal under Section 15 without the applicant having been heard.

Common Pitfalls in Responding to an Indian Patent Examination Report

Pitfall 1: Treating the Examination Report as a Final Rejection

The examination report is not a rejection. An applicant who allows the 9-month response window to expire without filing loses the application permanently. Rules 24B(5) and (6) are excluded from Rule 137 condonation. The only recourse is a new application with a later priority date and no guarantee against intervening prior art.

Pitfall 2: Introducing New Matter in Claim Amendments

The most common substantive error is an amendment incorporating a feature from drawings or description without verifying explicit textual support in the specification. Where the Controller refuses an amendment on new matter grounds and the applicant does not correct it within the 9-month window, the application may be refused.

Pitfall 3: Missing the Form 3 Trigger and the Divisional Window

Two independent deadlines are frequently missed. First, the Form 3 obligation under Rule 12(2) is due within 3 months of the report date (extendable under Rule 12(5)) and must be diarised separately from the response deadline. The Section 8 disclosure framework is covered in the Statement and Undertaking guide on intepat.com. Second, where a unity objection is raised, divisional applications under Section 16 must be filed before the parent is granted or refused. There is no mechanism to extend this window after the fact.

Pitfall 4: Filing Late and Leaving No Room for an SER

Filing the response late in the 9-month window leaves no time to address an SER if one issues. File within the 6-month initial window as default practice, not the exception.

Responding to an Indian FER: What Determines the Outcome

The First Examination Report is the central document in Indian patent prosecution. The key disciplines are these: read every cited prior art document in full before drafting; cover every objection in a single complete response; verify every claim amendment against the original specification; and file within the 6-month initial window, treating the 9-month outer deadline as a safety margin, not a target.

The Patents (Amendment) Rules, 2024 tightened every FER deadline India applicants face. A structured FER response India practitioners build on the disciplines above resolves most objections in the first round. Once the patent is granted, annual renewal fees are payable from the third year; estimate them using the Patent Renewal Fees Calculator. For prosecution support, see our Patent Prosecution Services.
