I missed the 31-month national phase deadline in India. Can it be revived?
If the Indian national phase is not entered within thirty-one months, the international application stops having effect in India and never becomes an Indian application. There is no ordinary route back. A request to condone the delay is sometimes attempted, but the position is unsettled and the Controller's discretion governs. Treat the Indian right as lost until a professional confirms otherwise.
What the law actually says
A PCT application is a single international filing that reserves the option of seeking protection in the member states. It does not grant anything anywhere. To obtain rights in India, the applicant has to enter the national phase, and Rule 20 fixes the point by which that must be done: thirty-one months from the earliest priority date, or from the international filing date where no priority is claimed.
If that point passes without entry, the international application ceases to have effect in India. Nothing is pending here. That has knock-on effects people do not always anticipate. A divisional under Section 16 needs a pending Indian application, so no divisional is possible. There is no Indian file to amend, no examination to request, and nothing on which a patent of addition can hang.
Rule 138 gives the Controller a general power to extend a time prescribed by the Rules, or condone a delay, by up to six months on a request in Form 4. Whether that power reaches the national phase period is genuinely unsettled. The period comes from the Rules read with the international treaty framework, and different benches have taken different views on how far the Controller may relax it. Some late entries have been permitted on strong facts; others have not. It is a possibility, not an entitlement, and any request must be made inside the six-month window.
Two things are worth saying clearly. Missing India does not affect the other designated states, which run on their own national timetables. And the international application will have been published, which means the specification is prior art. A fresh Indian application for the same invention will meet the applicant's own international publication in the search report.
What follows from it
- The international application has no effect in India. There is no Indian application to prosecute, amend or divide.
- The priority date is lost for India. Any fresh Indian filing carries its own, later, date.
- The international publication is public and becomes prior art against any refiling for the same invention.
- No divisional and no patent of addition can be filed in India, because both need something pending or granted here.
- Competitors can operate in the Indian market without an Indian patent standing against them.
- Where Indian coverage was promised to an investor, a licensee or a joint development partner, contractual exposure may follow.
What options exist
Verify the deadline against the real priority date Usually available
The thirty-one months run from the earliest priority date, not from the international filing date, unless no priority was claimed. Where the priority chain includes more than one earlier application, or where a priority claim was withdrawn during the international phase, the calculation changes. Miscalculations are common and cheap to check. This should be done before anything is conceded to a counterparty or written into a diligence disclosure.
Seek condonation of the delay under Rule 138 Rarely available
A request in Form 4 with the prescribed fee, made within six months of the missed date, asking the Controller to extend the time or condone the delay. The request should give a specific and documented account of what went wrong rather than a general reference to inadvertence. Whether the rule reaches the national phase period has been argued both ways, so this is a request that may or may not be entertained, decided at the Controller's discretion.
Approach the High Court Rarely available
Where the failure came from something outside the applicant's control, such as a documented breakdown in transmission or an error by an office rather than by the applicant, some applicants have sought relief from a High Court. Results vary and the applicant's own promptness weighs heavily. It is expensive, slow and unpredictable, and it cannot be built into a filing strategy.
File in India for later developments only Limited
Technical work done after the international specification was drafted, and not disclosed in it, may be filed as a new Indian application on its own merits. This is a different invention with a later date, not a recovery of the old one. The published international specification will be cited against anything that overlaps, so the scope of what remains has to be assessed document by document.
The labels above describe how often a route is realistically available in general practice — not a prediction about your matter. Relief that depends on the Controller's discretion is never an entitlement.
How to stop it happening again
- Diarise the thirty-one month date from the earliest priority date on the day the international application is filed, not later.
- Instruct Indian counsel at least two months ahead, so translations, powers of attorney and supporting documents are ready in time.
- Record in writing who is responsible for Indian entry: the head office, foreign counsel, or the Indian agent. Assumed ownership is how deadlines are missed.
- Where budgets force a country to be dropped, take and record that decision early, so it is a choice rather than a lapse.
- Keep proof of instructions sent and acknowledged. If relief is ever sought, that record is the case.
A Hyderabad diagnostics company and a lost handover
Anvaya Diagnostics Pvt Ltd filed an international application on a lateral-flow assay through a foreign associate. National phase entries in Europe and Japan were handled by that associate. India was to be handled directly by the head office, because the company wanted to use its own local agent. The in-house counsel who held that instruction left, and the replacement inherited a folder without a deadline list. The thirty-one month date passed by about seven weeks before anyone noticed. Their Indian agent filed a request in Form 4 under Rule 138 explaining the handover in detail, on the clear understanding that it might not be entertained. In parallel, the company reviewed what had been developed since the international filing, identified a reagent stabiliser not described in the specification, and prepared a fresh Indian application for it. The European and Japanese entries were unaffected. This account is a simplified illustration and not a template for any real file.

Questions people ask
Is the thirty-one months counted from the PCT filing date?
Usually not. It runs from the earliest priority date claimed in the international application. Only where no priority is claimed does it run from the international filing date itself. Because many applications claim priority from an earlier national filing, the two dates can be a year apart, and mistaking one for the other is a well-known way of losing a case. The priority chain on the actual application should be checked rather than assumed.
Does missing India affect my other designated countries?
No. Each designated state has its own national or regional entry requirements and its own consequences for missing them. Failing to enter in India does not disturb entries made in Europe, the United States, Japan or anywhere else. What it does affect is the commercial picture, because a portfolio with a hole in one of the largest markets is valued differently and may trigger disclosure obligations under investment or licensing agreements.
Will Rule 138 rescue a missed national phase entry?
Nobody can honestly promise that. The rule gives the Controller a discretionary power over times prescribed by the Rules, capped at six months. How far it extends to the national phase period has been litigated and the answers have not been uniform. Some applicants with strong, documented reasons have been permitted to enter late; others have not. Anyone presenting this as a reliable safety net is overstating it. The request must in any event be made within the six-month window.
Can I file a fresh Indian application for the same invention?
You can file, but the international application will have been published, and that publication is citable prior art from its date. An examiner will find it. Claims covering what the international specification already disclosed or made obvious are unlikely to survive. What can sometimes be pursued is later technical work that the earlier document does not describe. That assessment requires a careful comparison, which a patent professional must carry out on the actual documents.
Does the PCT itself allow late entry to be reinstated?
The international framework contains machinery under which a designated office may reinstate rights lost through a missed time limit, but how far any particular office applies it depends on that office's own law and on any reservations it has made. It is not a uniform global right. In India the position must be checked against the current Rules and practice rather than assumed from what applies in another country. Do not treat reinstatement as available until it has been confirmed.
