Patent renewal in India: fees, deadlines and how universities stop patents lapsing

A university can spend years and lakhs of rupees getting a patent granted, then lose it because a ₹800 fee was not paid on time. It happens more often than anyone admits. The inventor has moved on, the IPR cell has changed hands and the renewal reminder went to an old email address.

This guide is for technology transfer offices, IPR cells and research deans who manage patent portfolios. It covers when renewal fees fall due in India, what educational institutions pay, what to do if a deadline is missed, and how to build a renewal process that does not depend on one person's memory.

How patent renewal works in India

Under Section 53 of the Patents Act, 1970, a patent lasts 20 years from the date of filing. It stays in force only if the renewal fee is paid each year. Rule 80 of the Patents Rules, 2003 sets out how.

The key points:

• No renewal fee while the application is pending. Fees start only after grant.
• The first renewal fee is for the third year. Years 1 and 2 are covered without a renewal fee.
• Each fee is paid in advance, before the start of the year it covers. Years are counted from the date the application was filed (the "date of patent"), not from the date of grant.
• Patents granted late pay the backlog together. Most Indian patents are granted well after the second year. The accumulated renewal fees for the years already passed must then be paid within three months of the date the grant is recorded in the register.
• You can pay several years at once. Since the Patents (Amendment) Rules, 2024, paying renewal fees in advance for at least four years through the electronic mode earns a 10% reduction on those fees.

What universities pay

Since the Patents (Amendment) Rules, 2021, educational institutions pay the same lower fees as natural persons, startups and small entities. That cut their official fees by about 80% compared with the "others" category.

Annual renewal fees from the First Schedule to the Patents Rules:

Two practical notes. First, if a patent is co-owned with a company that does not qualify for the lower fee, check which fee category applies to the joint application before paying. Second, fees are revised from time to time, so confirm the current schedule on the IP India website before each payment cycle.

Kept for the full 20 years, one patent costs an educational institution ₹76,800 in renewal fees (₹3,200 + ₹9,600 + ₹24,000 + ₹40,000). More than half of that falls in the last five years, which is why the keep-or-drop review below matters.

What happens if you miss a renewal deadline

Missing the due date does not end the patent immediately. There are two safety nets, and both cost more than paying on time.

1. The six-month extension. The deadline can be extended by up to six months on request in Form 4, with an extension fee for each month. The patent is safe if the renewal fee and the extension request are filed within that period.

2. Restoration under Section 60. If the fee is still not paid, the patent ceases to have effect. The patentee can apply to restore it in Form 15, but only within eighteen months from the date the patent ceased. The Controller must be satisfied that the failure to pay was unintentional and that there was no undue delay in applying. The application is published and can be opposed. If restored, the law protects people who began using the invention while it had lapsed, so restoration is not a full undo.

After the 18-month window closes, the patent cannot be restored.

Why university patents lapse

In practice, lapses rarely happen because someone decided to drop a patent. They happen because of process gaps:

• Deadlines live in one person's spreadsheet, and that person moves on.
• The grant goes unnoticed. The three-month window to pay accumulated fees after grant is missed because nobody was watching the application.
• Payment approval is slow. Finance needs a purchase approval, the approval takes six weeks, and the fee is due in four.
• Correspondence goes to an old agent or address. Reminders from the patent agent never reach anyone with authority to pay.
• Nobody owns the keep-or-drop decision, so the patent is neither renewed nor consciously abandoned.

A renewal process that works

You do not need a large team. You need a single record, clear ownership and decisions made ahead of time.

1. Keep one register of every application and patent. For each: number, filing date, grant date, co-owners, licensee, next renewal date, next Form 27 date and the inventor contact.
2. Count from the right date. Renewal years run from the filing date. Recalculate the schedule the day a grant is recorded, and flag the three-month backlog payment at once.
3. Set reminders at 90, 60 and 30 days, sent to a shared mailbox, not to one person.
4. Pre-approve renewal budgets annually. Agree the year's renewal spend with finance in advance so individual payments do not wait for approval.
5. Pay multi-year where you are sure. For patents you will certainly keep, paying four or more years in advance electronically earns the 10% reduction and removes four deadlines.
6. Review each patent before the fee steps up. Before years 7, 11 and 16, decide keep or drop with the inventor and the TTO. Is it licensed? Is there active interest? Abandoning deliberately is fine. Lapsing by accident is not.
7. Align with Form 27. The three-yearly working statement is a natural point to review the whole portfolio. Our Form 27 guide has the dates.
8. Make licensees share the job. If a patent is licensed, the licence should say who pays renewals and who tracks them. See our article on how university technology transfer works for where these duties usually sit.

A dedicated system makes this far easier than spreadsheets. Zernyx IPMS is built for universities and research institutions to manage patents, filings and IP portfolios end to end, so renewal dates, Form 27 cycles and licence obligations sit in one place with reminders the whole team can see.

Common mistakes

• Counting renewal years from the grant date. They run from the filing date.
• Waiting for the Patent Office to send a reminder. Do not rely on one. The duty to pay is the patentee's.
• Assuming restoration is a formality. You must show the lapse was unintentional, and others can oppose.
• Paying the "others" fee by mistake, or the lower fee when a co-owner does not qualify. Check the category once and record it.
• Renewing everything forever. In the last five years each patent costs the most. Renew the ones with a reason.

FAQ

When is the first renewal fee due for a patent in India?

The first renewal fee is for the third year, counted from the filing date. If the patent is granted after that point, which is common, all accumulated renewal fees are paid within three months of the grant being recorded in the register.

How much is the patent renewal fee for an Indian university?

Educational institutions pay ₹800 a year for years 3 to 6, ₹2,400 for years 7 to 10, ₹4,800 for years 11 to 15 and ₹8,000 for years 16 to 20. Check the current First Schedule on the IP India website before paying.

Can a lapsed patent be restored in India?

Yes, if an application in Form 15 is made under Section 60 within 18 months from the date the patent ceased, and the Controller accepts that the failure to pay was unintentional. Restoration can be opposed and is not guaranteed.

Is there a discount for paying renewal fees in advance?

Yes. Under the Patents (Amendment) Rules, 2024, renewal fees paid in advance for at least four years through the electronic mode get a 10% reduction.
