Renewal
Renewal fee is to be paid only from the third year onwards and is to be paid before the expiry of the second year from the date of patent. Renewal fee is payable only after patent grant. If a patent is not granted within two years from the date of patent, then the renewal fees accrue till such time a patent is granted. All the renewal fees, which accumulate before the grant of patent, are paid upon patent grant and within three months from the date of recordal (the date, on which a patent is recorded in the Register of Patents). Subsequent renewal fees are due to be paid on or before the anniversary of the date of patent. Six months’ grace period is available to pay renewal fees on payment of monthly surcharge. Failure to pay renewal fees leads to cessation of patent on the date on which the renewal has been due.

Restoration of patent
If a patent lapses due to non-payment of renewal fees, such patent can be restored, if necessary application for restoration is filed within 18 months from the date of cessation.
