Patent Prosecution in India: Examination, Opposition and Portfolio Handovers
You have a patent application moving through Indian examination, a granted patent under post-grant opposition, a portfolio to transfer, or a foreign filing licence to secure. Patent prosecution is the stage at which claim scope is tested against prior art, statutory exclusions, formal requirements, and the Controller's objections. Intepat handles FER and SER responses, Section 14 hearing representation, pre-grant and post-grant opposition defence, agent transfers and portfolio continuity, and foreign filing licence support for Indian-resident applicants. Each matter is handled by Registered Indian Patent Agents authorised under the Patents Act, 1970.

What Indian patent prosecution covers
Examination response and FER management
After a patent application is published and a request for examination is filed, the Indian Patent Office issues a First Examination Report (FER) setting out objections on patentability, subject matter, or formal requirements. Subsequent Examination Reports (SERs) may follow. Applicants must place the application in order for grant within six months of the FER, with a limited extension if requested within the prescribed time. Each response is calibrated to the specific objections raised, with claim amendments proposed only where supported by the application as filed.
Section 14 hearing representation
Where examination objections are not resolved through written responses, the Controller may schedule an oral hearing under Section 14 of the Patents Act, 1970. Intepat's patent agents attend hearings at all four Patent Office locations and by video conference, preceded by a position paper addressing every outstanding objection.
Pre-grant opposition defence (applicant-side)
Under Section 25(1) of the Patents Act, 1970, any person may file a representation opposing the grant of a published application before grant is issued. Grounds include lack of novelty, lack of inventive step, subject matter exclusions, and disclosure failures. Where a representation proceeds to applicant response, Intepat reviews the opponent's grounds, prepares the reply and supporting submissions, and attends any hearing fixed by the Controller.
Post-grant opposition defence (patentee-side)
Under Section 25(2) of the Patents Act, 1970, any interested person may oppose a granted patent within one year of the date of publication of grant. Proceedings involve an Opposition Board constituted by the Patent Office, which reviews submissions from both sides before making a recommendation to the Controller. Defence work is coordinated with the patentee's broader portfolio position where parallel validity challenges are pending.
Portfolio handovers from other firms
Applicants and in-house teams sometimes transfer an active prosecution portfolio from one Indian agent to another. Handovers require statutory recordal of the change of authorised agent, followed by a prosecution history review to ensure no pending deadlines or outstanding objections are missed. Where an incoming application has an unaddressed FER or an approaching deadline, the response is prioritised before completing transfer formalities.
Foreign filing licence preparation
Indian-resident applicants who wish to file a patent application outside India must either first file in India and allow six weeks without a secrecy direction, or obtain a foreign filing licence from the Controller before making the foreign filing. Intepat prepares foreign filing licence applications, reviews the invention disclosure for compliance, and advises on filing sequence and timing.
The Indian patent prosecution lifecycle
Prosecution is governed by the Patents Act, 1970 and the Patents Rules, 2003. Sections 14 and 15 govern examination and the Controller's power to refuse or require amendments. Section 21 sets the obligation to address examination requirements within the prescribed period; failure results in the application being deemed withdrawn. Section 25(1) governs pre-grant representations; Section 25(2) governs post-grant oppositions by interested persons.
After a request for examination is filed, the Patent Office issues the FER. The applicant must address outstanding objections within six months of the FER date, with a limited extension if applied for within the prescribed time. Where the Controller remains unsatisfied, a Section 14 hearing is scheduled. On resolution of all objections, the patent is granted and published; the one-year post-grant opposition window opens on that publication date. The examination request deadline was amended for applications filed on or after 15 March 2024.
How Intepat handles prosecution
Examination responses are drafted with the examiner's specific objections as the starting point. Intepat reviews the prior art cited in the FER, assesses whether each objection is well-founded, and prepares arguments addressed to the particular grounds raised. Subject matter objections under Section 3 are addressed with reference to current guidelines and judicial decisions.
Claim amendments are proposed only where the prosecution record and the claims as filed support the amended scope. The objective is the broadest defensible claim scope, not reduction beyond what the objection requires. Intepat handles prosecution across mechanical, electronics, software, AI and machine learning, telecommunications, medical devices, pharmaceuticals, chemistry, biotechnology, and interdisciplinary inventions.
For opposition matters, the technical and legal review proceeds in parallel. The evidence bundle is managed, technical witnesses are coordinated where required, and all submissions are filed within statutory timelines. Portfolio handover engagements begin with a prosecution status audit that produces a file-by-file summary of status, pending deadlines, and matters requiring immediate attention; the portfolio is accepted only after the client has been briefed on any urgent actions.
Documents and inputs required
To begin a prosecution engagement: the application number and copy of the patent application as filed; the FER, opposition notice, or relevant Patent Office communication; prior art cited; and applicant authorisation. For portfolio handovers, the complete prosecution history for each application. For foreign filing licence matters, a description of the invention and the target jurisdiction.
Common pitfalls Intepat protects against
Missing the examination response deadline.
The statutory period for responding to a FER is fixed, with a limited extension available only if applied for before expiry. Failure to respond within the prescribed period results in the application being deemed withdrawn under Section 21 of the Patents Act, 1970. All deadlines are docketed with advance notices ahead of each expiry.
Narrowing claims unnecessarily.
Claims are amended to the extent the specific prior art or subject matter objection requires, not beyond. Over-amendment is a recognised source of enforceability problems in granted patents.
Incomplete inventive step arguments.
Inventive step objections require a technical analysis of the prior art combination proposed and a substantive argument on why the claimed invention would not have been obvious. Responses addressing only secondary references consistently fail to resolve the objection.
Loss of continuity during portfolio handovers.
Where the prior agent has not maintained complete records, or deadlines fall between the notice of transfer and completion of formalities, applications can lapse without the incoming agent being aware. Intepat's handover protocol includes a status audit for each application before transfer is accepted.

Patent Prosecution FAQs
What does Intepat's patent prosecution service cover?
This service covers post-filing interactions with the Indian Patent Office: FER and SER response preparation, Section 14 hearing representation, pre-grant opposition defence under Section 25(1) of the Patents Act, 1970, post-grant opposition defence under Section 25(2), prosecution handovers from other agents or firms, and foreign filing licence support for Indian-resident applicants. Patent drafting, initial filing, and renewal fee payment are handled under separate services.
Who should use this service, and at what stage?
Appropriate at any point after an application has been filed. Common entry points: receipt of a First Examination Report; notification that an opposition has been filed against an application or granted patent; a decision to transfer prosecution responsibility from another Indian agent; and a requirement to obtain a foreign filing licence before a planned foreign filing.
How long does prosecution typically take?
Timelines vary considerably depending on technology area, examination queue, number of objections, hearing rounds, and whether opposition arises. Expedited examination may shorten the timeline. Intepat controls applicant-side deadline compliance and response quality; Patent Office examination and hearing timelines remain outside the applicant's direct control.
How are prosecution fees structured?
Fees are structured on a matter-by-matter basis: examination response preparation, hearing attendance, opposition proceedings, and portfolio handover audits are each scoped and priced separately. Government fees payable to the Indian Patent Office are billed at cost. Intepat does not charge a flat retainer; each matter is engaged on a defined-scope basis with fee estimates provided at the outset.
What most affects the outcome of prosecution?
The quality of the original specification and claims. An application with a well-structured disclosure, independent claims of appropriate scope, and clear support in the description will typically produce fewer objections and resolve them more efficiently. A strong prosecution strategy cannot fully cure a materially deficient specification, but can often preserve broader claim scope where the original disclosure provides support. For opposition matters, the grounds raised and the prior art the opponent presents are the primary considerations.
