The question we are asked most often after filing a patent application in India is how long it will take. The honest answer is that the statutory deadlines are fixed and knowable, while the queue times between them are not, and vary by technical field, by patent office branch, and by the workload of the particular examiner.
This article separates the two. Where a period is set by the Patents Act, 1970 or the Patents Rules, we state it. Where it depends on Registry throughput, we describe the pattern rather than quoting a number, because published pendency figures move and a figure printed here would be stale quickly. Applicants planning around specific dates should confirm the current position rather than relying on any general article, including this one.
The fixed points in the timeline
An Indian patent application moves through a sequence of dated events. The ones set by statute or rule are:
| Event | Period |
|---|---|
| Complete specification after provisional | Within twelve months of the provisional filing |
| Publication | After eighteen months from priority date, or earlier on request |
| Request for examination | Within the prescribed period from priority or filing, whichever is earlier |
| Reply to First Examination Report | Within the prescribed period from the date the report is issued |
| Pre-grant opposition | Any time after publication and before grant |
| Post-grant opposition | Within twelve months of publication of grant |
| Renewal fees | From the third year onwards, annually |
Two of these are worth taking slowly, because they cause more lost applications than anything else.
Request for examination is not automatic
An Indian patent application is not examined unless examination is requested. Filing is not enough. The request is made on the prescribed form with the prescribed fee, and if the period passes without a request, the application is treated as withdrawn. There is no discretion to revive on that ground.
The period for making the request has been shortened by amendment over the years, and an applicant relying on remembered practice from an earlier period can miss it. Confirm the current period against the Rules as they stand at your filing date. This is the single deadline we would advise every applicant to diarise on the day of filing.
The reply period to the examination report is real
When the First Examination Report issues, the applicant has a fixed period within which to place the application in order for grant, meaning to respond to every objection raised. The period runs from the date the report is issued, not the date it is noticed. Extensions are available in limited circumstances and on payment, within a further capped period, but the outer limit is absolute. An application that is not in order by then is deemed abandoned.
Objections in an Indian FER routinely span novelty, inventive step, patentable subject matter under Section 3, sufficiency and clarity under Section 10, formal requirements, and the Section 8 obligation to keep the Controller informed about corresponding foreign applications. Preparing a substantive reply, sometimes with claim amendments, is not a short task, and applicants who begin it near the deadline are choosing to do it badly.
Where the queue time sits
Between the statutory milestones, applications wait. The waiting happens in two main places.
Between request for examination and issue of the First Examination Report. This is the longest and most variable gap. It depends on the technical field, since examiners are allocated by discipline and some disciplines carry far heavier backlogs than others, and on which of the four patent office branches has jurisdiction over the application.
Between the reply and grant or hearing. If the reply resolves the objections, the application can proceed to grant. If it does not, a hearing is scheduled, and scheduling depends on the Controller's list.
The Indian Patent Office has invested substantially in reducing pendency, including through recruitment of examiners and digitisation of prosecution. The direction of travel over recent years has been towards shorter waits. That said, an applicant should plan on the basis that ordinary examination takes a matter of years from request to grant, not months, and should treat any specific figure with caution unless it comes from current official statistics.
Expedited examination
The Rules provide for expedited examination on request, subject to eligibility. The categories of applicant and application eligible for expedited treatment have been widened by successive amendments, and now cover a broader range than when the mechanism was introduced. Commonly available grounds include:
- The applicant is a startup, as defined for these purposes
- The applicant is a small entity, or falls within another specified applicant category
- India has been indicated as the International Searching Authority or International Preliminary Examining Authority in the corresponding PCT application
- The application falls within a sector notified by the Government
- The application is eligible under a Patent Prosecution Highway arrangement with a partner office, where such an arrangement is in force and within its participation limits
Eligibility and the applicable fee should be checked against the Rules as currently in force, since both the categories and the fee levels have been revised more than once. Expedited examination carries a higher official fee than ordinary examination, and the request must be supported by evidence of eligibility.
Where it is available, expedited examination materially compresses the wait to the First Examination Report. It does not change the applicant's own reply deadline, and it does not shorten opposition periods.
Our superfast services practice deals with matters where the timeline is the constraint, including assessing whether an application qualifies for expedited treatment before the request for examination is filed.
Practical planning
A few things follow from the structure above that are worth building into a filing strategy.
Decide about examination timing deliberately. Requesting examination immediately on filing starts the clock and gets the application into the queue earliest. Some applicants prefer to defer to the end of the permitted period, to preserve flexibility and delay cost while the commercial position clarifies. Both are legitimate. What is not legitimate is defaulting into a late request by inattention.
Keep Section 8 current. The obligation to inform the Controller of corresponding applications filed outside India, and to supply information about their prosecution when required, is continuing. Non-compliance is a ground of opposition and revocation. It is a paperwork obligation that has cost applicants granted patents.
Diarise renewals from year three. Renewal fees fall due annually from the third year, including while the application is still pending, in which case accrued fees become payable after grant. Lapse for non-payment is common and restoration is limited.
Plan foreign filings from the priority date, not the Indian timeline. The twelve-month Convention period and the thirty or thirty-one month PCT national phase deadlines run independently of what is happening in India. An applicant waiting to see whether the Indian application is allowed before deciding on foreign filings will usually be waiting past the deadline. The worldwide IPR page sets out the routes.
Budget for prosecution, not just filing. The cost of an Indian patent is spread across filing, examination request, one or more substantive replies, possibly a hearing, and renewals. Applicants who budget only for filing tend to under-resource the reply, which is where the scope of the granted claims is actually determined.
Where we can help
We handle drafting, filing and prosecution before all four branches of the Indian Patent Office, including expedited examination requests, FER replies and hearings. Details are on the patent practice page, and applicants at an earlier stage may find the innovation and startups page useful.
If you have an application pending and want a view on where it sits in the timeline, or an examination report you need answered, send us the application number through the contact page and we will look at it.
