I missed a patent renewal fee. Has my patent lapsed?
A renewal fee that has fallen due can still be paid within six months of the due date, with the prescribed extension fee. If nothing is paid in that window, the patent ceases. A ceased patent may be restored only if an application is made within eighteen months of cessation. Once those eighteen months pass, there is no route back.
What the law actually says
Section 53 gives an Indian patent a term of twenty years from the date of filing, but only for as long as the renewal fees are paid. Rule 80 sets out the mechanics. Fees run from the third year and are payable before the expiry of the preceding year. Where a patent is granted late, after several renewals have already fallen due, the Rules allow a catch-up period from the date the patent is entered in the register.
A missed payment is not immediately fatal. The Rules allow the fee to be paid within a further six months, on a request in Form 4 with the extension fee prescribed in the First Schedule. Nothing has to be justified and no discretion is involved. This is routine, and most missed renewals are dealt with here.
If the six months passes without payment, the patent ceases to have effect from the date the fee fell due, and the cessation is published. From that date the invention is free for anyone in India to make, use or sell. Sections 60 and 61, with Rules 84 and 85, then provide the only way back: an application for restoration in Form 15, made within eighteen months from the date of cessation. The patentee must satisfy the Controller that the failure to pay was unintentional and that there was no undue delay. The Controller decides first whether a prima facie case is made out, the application is published, and any person interested may oppose it.
Two limits deserve plain statement. Restoration is discretionary and not automatic, and Section 62 protects people who began working the invention while the patent was not in force, so the restored patent comes back with those rights carved around it. And the eighteen months is a period fixed by the Act itself. The Controller's power under Rule 138 reaches times prescribed by the Rules, not periods set by the statute, so it cannot be used to enlarge it.
What follows from it
- If the six-month extension window closes without payment, the patent ceases to have effect from the date the fee fell due.
- Cessation is published, and from that date anyone in India may work the invention without infringing.
- No infringement action lies for anything done while the patent was not in force, even if it is later restored.
- If restoration is granted, Section 62 protects third parties who started using the invention in good faith during the lapse, so the recovered monopoly is narrower than the original.
- Once eighteen months from cessation has passed, the Act provides no restoration route. The patent is permanently in the public domain.
- Where a licensee, assignee or renewal agent was responsible for payment, the loss usually turns into a contractual dispute rather than a recoverable right.
What options exist
Pay within the six-month extension window Usually available
A renewal that has fallen due may still be paid within six months, on a request in Form 4 with the extension fee prescribed in the First Schedule. No reason is required and no discretion is exercised. The only requirement is that the payment lands inside the window. If a patent is only a few months overdue, this is almost always the answer, and it should be checked before anything more elaborate is considered.
Apply for restoration within eighteen months of cessation Limited
An application in Form 15 under Section 60, supported by evidence explaining why the failure to pay was unintentional and why there was no undue delay in applying. The Controller decides whether a prima facie case exists, may call for a hearing, and publishes the application so that interested persons can oppose it under Rule 85. If restoration is allowed, the unpaid fees and any additional fee must be paid as directed. Success depends on the quality of the explanation and the evidence behind it.
Relief after the eighteen months has passed Rarely available
There is no provision for it. The eighteen-month period sits in the Act, not in the Rules, so the Controller's general power to extend time and condone delay does not reach it, and a rule cannot enlarge a statutory period. High Court writ jurisdiction is the only theoretical avenue and is rarely successful in this setting. Readers in this position should be told plainly that the patent is most likely gone for good.
Review the rest of the family and the portfolio Usually available
Where one renewal has been missed, others are often at risk from the same broken process. Related patents in the same family, divisionals, patents of addition and foreign counterparts should all be checked at once, and the renewal responsibility documented. This does not recover the lapsed patent, but it usually prevents the second loss.
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
- Set the renewal dates for the whole life of the patent when it is granted, rather than adding one year at a time.
- Review each patent's commercial value before its fee falls due, so a lapse is a decision you took and not an accident.
- Where an agent or a renewal service holds the docket, ask for written confirmation of every payment made.
- Update the address for service, the email and the responsible person on the register whenever any of them changes.
- Where a patent is assigned or licensed, state in the agreement who pays renewals and who confirms payment to whom.
A Coimbatore pump patent that lapsed quietly
Netravati Pumps Pvt Ltd held a patent on an impeller housing. Renewals had always been handled by their original agent. When the company changed agents, the renewal docket was one of several things that did not survive the handover. The ninth-year fee was never paid, the six-month window passed, and the patent ceased. Nobody at the company knew, because cessation is published rather than posted to the patentee. Roughly twenty-two months later a competitor in the same district began selling a near-identical housing. The company's new counsel checked the register and found the patent had ceased. The eighteen-month restoration window had closed about four months earlier. The competitor's manufacture had been lawful from the date of cessation. A separate patent on the volute geometry was still in force and was reviewed for whatever it covered. This is a simplified illustration, and every restoration question depends on its own dates and evidence.

Questions people ask
When do renewal fees start becoming payable?
Under Rule 80 renewal fees run from the third year of the patent, and each fee is payable before the expiry of the preceding year, measured from the date of the patent. Where the patent is granted long after filing, several years' fees may already have fallen due at grant. In that situation the Rules give a short catch-up period from the date the patent is entered in the register, which itself may be extended on request. The exact periods should be checked against Rule 80 as it currently stands.
Is the six-month extension automatic?
It is available on a request in Form 4 with the extension fee prescribed in the First Schedule, and no reasons need to be given. In that sense it is straightforward. What it is not is unlimited. The payment and the request have to be completed within six months of the date the fee fell due. Missing that window changes the situation entirely, because the patent then ceases and the only remaining route is restoration, which is discretionary and much harder.
What does an application for restoration have to show?
Section 60 requires the application to be made within eighteen months from the date the patent ceased to have effect, in Form 15, and to be supported by evidence. The patentee must satisfy the Controller that the failure to pay the renewal fee was unintentional and that there has been no undue delay in applying. A vague statement about oversight is weak. What helps is a specific account, supported by records, of how the payment came to be missed and when the patentee found out. The Controller then decides whether a prima facie case exists.
If my patent is restored, can I sue over what happened while it was lapsed?
No. Section 62 limits what a restored patent can reach. Proceedings cannot be brought for infringing acts committed between the date of cessation and the date the restoration application was published. In addition, a person who began working the invention, or made serious preparations to do so, during that gap is generally protected in continuing. So restoration returns the patent, but it does not return the period the public was free to act, and it may leave a competitor lawfully in the market.
Can the eighteen-month restoration period be extended?
Not by the Controller. Rule 138 allows extension or condonation for times prescribed by the Rules, and the eighteen months in Section 60 is prescribed by the Act itself. Courts have consistently held that a rule cannot enlarge a period the statute has fixed. This is one of the places where the honest answer is that the door is closed. Anyone told otherwise should ask which provision is being relied on before spending money on the attempt.
