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.
Documents

Clear, current documents matter more than a long checklist. Names, dates of birth and addresses should match across records.

- Map ownership, beneficial ownership and pricing
- Allow time for apostilled or consularised documents

- Receive funds through permitted banking channels
- Complete RBI/FEMA reporting and keep the bank evidence
- Coordinate tax and ongoing compliance advice early

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.
