What Is Patent Renewal?
A quick, plain-language explanation before the details.
Patent renewal is the payment of annual annuity fees that keep a granted patent in force. Pay them on time and your patent stays valid for its full 20-year term; miss them and it lapses.
Under the Patents Act, 1970 and the Patents Rules, a patent is kept in force by paying the prescribed renewal (annuity) fee. Renewal fees become due from the third year onwards and are payable before the expiration of each succeeding year of the patent term, calculated from the date of filing.
Renewals are filed with the Office of the Controller General of Patents, Designs & Trade Marks (CGPDTM) through the Indian Patent Office, via the e-filing portal at ipindia.gov.in.
A granted patent is valid for 20 years from the date of filing, provided each renewal fee is paid on time. A 6-month grace period (with surcharge) is available; beyond that the patent lapses and can only be revived by restoration.

Talk to an Expert →Why Patent Renewal Matters
A patent is only an asset while it is in force. Renewal is what keeps your exclusive rights alive — here is why paying annuities on time is critical.
-
01
Keep Your Rights Alive
Timely renewal keeps your exclusive right to make, use, sell and license the invention in force. Miss an annuity and those rights can be lost.
-
02
Protect the Full 20-Year Term
A patent lasts 20 years from filing only if every renewal fee is paid. Consistent renewal secures the maximum protection the law allows.
-
03
Preserve Asset Value
An in-force patent is a licensable, assignable and mortgageable asset. A lapsed patent loses that commercial and balance-sheet value.
-
04
Retain Enforceability
You can only sue for infringement while the patent is in force. Renewal keeps your legal remedies — injunctions and damages — available.
-
05
Avoid the Lapse Trap
A single missed annuity, even within the grace period, can end in lapse. Proactive tracking of every due date avoids an avoidable loss.
-
06
Support Licensing Deals
Licensees and investors expect a live, well-maintained patent. Clean renewal records strengthen your position in negotiations and diligence.

What You’ll Receive
What Do You Need to Renew a Patent?
Renewal is straightforward once the patent is identified. Keep the patent number, filing date and applicant details ready — everything is collected securely online.
Patent Details
To identify the patent- Patent number and title
- Date of filing (the anniversary is calculated from this)
- Date of grant
- The renewal year(s) currently due
Patentee / Applicant
Who holds the patent- Name and address of the patentee(s)
- Applicant category — individual, startup, small entity or others (affects fee)
- Identity proof of the patentee
- Startup / MSME certificate (if claiming reduced fee)
Authority & Restoration
Where applicable- Power of authority (Form 26) for the patent agent
- Assignment / licence details, if the holder is not the original patentee
- For a lapsed patent — evidence that the failure to pay was unintentional
- Details of the date the patent ceased to have effect
Renewal starts from year 3
No renewal fee is due for the first two years. Renewal (annuity) fees fall due from the 3rd year onwards and are payable before each anniversary of the filing date.
6-month grace period
If you miss an anniversary you can still pay within a 6-month grace period on payment of the prescribed surcharge — but do not rely on it as a routine buffer.
Lapse is serious
If the fee is not paid within the grace period the patent lapses and your rights cease. Restoration is possible but discretionary and time-limited.
Startup / small-entity fee
Recognised startups, small entities and natural persons pay substantially lower official renewal fees. Keep your Startup India / MSME certificate handy.

We’ll identify what your case needs →How Patent Renewal Works (Step by Step)
Renewals are filed online through the Indian Patent Office e-filing portal at ipindia.gov.in.
Identify the patent & due date
Confirm the patent number and date of filing, then determine which renewal year is due and its anniversary deadline.
Compute the renewal fee
Calculate the correct annuity fee for the applicable year and applicant category (individual, startup, small entity or others).
File the renewal before the anniversary
File the renewal with the prescribed fee on the IPO e-filing portal before the expiry of the relevant year.
Use the grace period if needed
If the anniversary is missed, file within the 6-month grace period with the additional surcharge to keep the patent in force.
Restore, if the patent has lapsed
If the patent has already lapsed, file an application for restoration within 18 months, supported by evidence that non-payment was unintentional.
Confirm status & schedule next renewal
Obtain the payment receipt, confirm the patent remains in force, and record the next annuity due date.

| Stage | Expected Time |
|---|---|
| First & second year | No renewal fee due |
| From the 3rd year onwards | Renewal fee payable before each anniversary of filing |

Renewal fees become due from the third year and are payable annually before each anniversary of the date of filing, keeping the patent in force up to 20 years. A 6-month grace period with surcharge is available. If the fee is still unpaid the patent lapses, and restoration must be applied for within 18 months of the date the patent ceased to have effect.
