Indian Patent Annuities Years 3-20: Rule 80 Grace, Late-Grant Rule, 10% Advance Discount

How-to · Patent Annuities

Updated for 2026 · Claw Editorial

An Indian patent does not lapse because it is weak. It lapses because someone missed a date. You must pay a renewal fee (an annuity) every year from the third year, and a missed payment can end the patent. This guide shows how to track those dates, what each year costs under Rule 80, how the six month grace works, and how to get a lapsed patent back. Last verified October 2026.

01Why annuity deadlines are missed

Patent renewal is simple on paper, but it fails in practice because the work is spread over twenty years. Three things cause most misses.

The clock runs from the filing date

The renewal year is counted from the date of the patent, which is the filing date, not the grant date. A patent can take years to grant, so the first annuities may already be due when you hold the grant. Many owners count from the wrong date.

Ownership and files change hands

Inventors leave, firms change counsel, and companies merge. Reminders sit in one person’s calendar. When that person moves on, the date moves with them.

The amounts are small, so nobody owns the task

An early-year renewal can cost only a few thousand rupees. Because the cost is small, it does not get a budget line or an owner. The loss, however, is the whole patent.

A patent in India is lost for a few thousand rupees far more often than it is lost in court.

02The rules in one place

Renewal is governed by Section 53 of the Patents Act, 1970 and Rule 80 of the Patents Rules, 2003. In plain words:

• When it starts: the fee is due at the expiry of the second year from the date of the patent, and then every year after that, up to year 20.
• Payment window: the fee must reach the Patent Office before the expiry of the year (Rule 80(1)).
• Extension: the period can be extended by up to six months on a request in Form 4, with the extension fee from the First Schedule (Rule 80(1A)).
• Quote the details: while paying, quote the patent number, its date and the year for which you pay (Rule 80(2)).
• Advance payment: fees for two or more years may be paid in advance (Rule 80(3)). A 10% reduction applies when at least four years are paid in advance by electronic mode.
• Proof: the Controller credits the fee and issues a certificate that it has been paid (Rule 80(4)).

The rule text above follows the Patents Rules as published on Indian Kanoon and IP India. The 10% advance clause was added by the 2024 amendment.

03Rule 80 renewal fee table, years 3 to 20

This table gives the official renewal fee for each patent year. There are two columns: natural person, startup or small entity, and all others (large entities). The figures below are as understood after the Patents (Amendment) Rules, 2024. Fees dated and checked October 2026.

Add up the four bands and the total over years 3 to 20 is Rs 76,800 for the first column (4 x 800 + 4 x 2,400 + 5 x 4,800 + 5 x 8,000) and Rs 384,000 for large entities. These are our own sums from the table, before any discount, extension or physical filing surcharge.

Physical filing carries a 10% surcharge on the electronic fee, so file online. The extension fee for Form 4 is charged per month of delay.

Fees change with amendments. Always check the live fee schedule on ipindia.gov.in before you pay.

04Step by step: how to manage renewals

1. List every patent and its date of patent. Use the filing date (or the international filing date for national phase cases). Confirm the date in the Patent Office record, not from memory.
2. Work out the due date for each year. The fee for year 3 is due at the end of year 2. Put the due date and the last extended date (six months later) in a shared calendar.
3. Set three reminders. Remind at 90, 30 and 7 days before the due date. Send them to two people and one shared mailbox, not one person.
4. Name an owner and a backup. Write who pays, who approves the spend and who checks the receipt.
5. Decide each year: renew or let go. Fees rise steeply after year 10 and again after year 15. Review whether the patent is still used, licensed or worth defending.
6. Pay electronically. Pay through the IP India e-filing portal, quote the patent number, date and year, and save the receipt.
7. Check the Controller’s record. Confirm the fee is credited and keep the payment certificate in the file.

For a team with many patents, one register with owner, due date, last extended date and status is more useful than a diary of reminders.

05The grace period and Form 4

You can still pay up to six months after the due date if you ask for an extension in Form 4. This is Rule 80(1A).

Treat this as a safety net, not a plan. The extension costs money, and the fee is charged per month of delay, so paying in month five costs much more than paying on time.

• File Form 4 with the extension fee, and pay the renewal fee for that year, before the six months end.
• Do not wait for a reminder from the Patent Office. Do not assume one will come.
• If six months pass without payment, the patent ceases and you must use the restoration route below.

06The 10% advance payment discount

If you pay at least four years of renewal fees in advance by electronic mode, you get a 10% reduction on those fees.

Here is a worked example using the table above for a large entity. Paying years 7 to 10 together would be 4 x Rs 12,000 = Rs 48,000. With the 10% reduction, the payment would be Rs 43,200. A natural person, startup or small entity would pay 4 x Rs 2,400 = Rs 9,600, reduced to Rs 8,640.

Advance payment has two benefits: one payment removes four annual deadlines, and it saves money. The cost is that cash is tied up. If you might abandon the patent in two years, advance payment is a poor choice, and the fees you prepaid are not refunded.

07Late grant and restoration under Section 60

When the patent is granted late

If a patent is granted after the second year from filing, renewal fees for the years already past fall due. The commonly stated rule is that these may be paid within three months of the date the patent is recorded in the Register, and can be extended by Form 4 to a limit of nine months from that date.

This is the case people miss most, because the annuities for the pending years arrive with the grant order.

Restoring a lapsed patent

Section 60 allows a lapsed patent to be restored. The usual route is an application to the Controller within eighteen months of the lapse, showing that the failure to pay was unintentional or without undue delay. You then pay the overdue fees and any additional fee.

Restoration is publicly advertised and can be opposed. A third party who used the invention while the patent had lapsed may also have protection for that period. So restoration is a remedy, not a plan. Take legal advice before relying on it.

08Tools for tracking annuities

The right tool depends on how many patents you hold, and in how many countries. A fair summary:

• A spreadsheet and shared calendar: enough for a handful of Indian patents, if one person owns it and a backup checks it.
• Global annuity and docketing platforms such as Anaqua, Clarivate and Dennemeyer: built for multi-country portfolios and deadline payment services. They are the stronger choice when your patents sit in many jurisdictions.
• High volume IP docketing such as Iolite or JSK: suited to specialist IP firms handling a very large docket.
• An all-in-one India IP tracker: useful when your portfolio is mainly Indian and you also want court matters, hearings and trademark deadlines in the same place.

Pricing for the global platforms is quote based, so we do not state numbers. Check each vendor’s own site for current terms.

If your annuity risk sits inside a lender or NBFC process, see litigation search APIs for NBFCs and banks. For comparing case tracking tools, see best case tracking software in India.

09Where Claw fits

Claw is an all-in-one legaltech platform for Indian advocates, law firms, and corporate legal teams, combining AI-based case search, an AI legal assistant (Legal GPT), case management, and compliance automation across all Indian courts and tribunals.

Renewal is a date problem on the registry side. The court side is separate: whether a patent has been challenged, revoked or enforced lives in judgments, not in the fee record. Claw tracks cases, orders and hearings across 9,102 courts, benches and forums, with 30 crore+ judgments and results in under 5 seconds, covering the Supreme Court from 1950 and the High Courts from 1990. So you can see how a patent or its holder has fared in litigation while you keep the renewals alive.

Claw does not use customer documents to train AI models. Create a FREE Claw account to follow the court side of a patent by party or number. To search the wider body of law, see case search across Indian courts.
