Overview
How patent renewal works in India
A granted Indian patent is valid for 20 years from the filing date, subject to annual renewal fees.
Renewal fees are payable each year before the anniversary of the filing date, starting from the third year.
There is a grace period of six months to pay late, with an additional fee — after that, the patent lapses.
A lapsed patent can be restored through a restoration application, but only within a limited window and at the Controller's discretion.
Fees differ by applicant type — individuals, startups, small entities and large entities pay different rates.
Benefits
Why patent holders use us for renewals
Open each benefit to see what it means for you.
Deadlines tracked for the full 20 years
One missed annuity can kill a patent worth years of R&D. We diarise every due date from grant to expiry.
Correct fee, correct category
Startups and small entities pay less — but only if the paperwork claims it properly. We make sure you never overpay.
Lapse recovery handled
If a deadline was already missed, we assess whether restoration is still possible and file it properly with the reasoning the Controller expects.
Proof for your records
Every payment comes with official receipts and an updated status report — useful for investors, licensees and auditors.

Patent renewal process in India — step by step
You’ll see each stage, what’s pending and what we need from you — so filings don’t bounce back.
Step 1 of 5
Calculate which renewal year is due
Indian patents run for 20 years from the filing date, and renewal fees are payable annually starting from the 3rd year. We verify your exact due year from the Patent Office records.
Pay before the due date
We pay the annual renewal fee to the Patent Office before the deadline. The fee depends on your entity category and the year — paying on time keeps it cheapest.
Missed it? Use the 6-month grace period
The Patents Act gives you 6 extra months to pay with an extension fee. Miss that too and the patent lapses — though restoration can be sought within the statutory window, it is slow and uncertain.
Confirmation and docketing
We confirm the payment reflects in the official register and update your renewal calendar so next year's deadline never surprises you.
Next-year reminder set
We diary your next renewal 90 days out and remind you in time to pay at the standard rate. Annual reminders are included as long as the patent stays in force.

Not necessarily. There's a six-month grace period with an additional fee, and a restoration route after that. Talk to us quickly — the options narrow with time.
It depends on the patent's age and whether you're an individual, startup, small entity or large entity. Share your patent number and we'll quote exactly.
Yes — an authorised agent can pay on your behalf. That's precisely what we do, with receipts in your name.
Yes. Renewal is the patentee's obligation regardless of licensing. Some licence agreements pass the cost to the licensee — we can check yours.
You can simply let it lapse by not paying. Just make the decision deliberately — once lapsed beyond restoration, the invention enters the public domain.
