This is irrespective of the year of grant, the renewal fee is paid after the grant but from the second year onwards. The patent renewal fee is to be paid till the validity of the patent i.e. 20yrs from the date of filing.

Example: The fifth-year renewal fee must be submitted before the fourth year following the date of the patent expires. At the end of the second year following the date of the patent, as well as each successive year, a renewal fee is due. According to the Indian Patents Act, the patentee may even pay the renewal cost in advance for 2 years or more.

Another crucial thing to keep in mind is that pending fee payment must be made within three months of the patent grant date, as recorded in the patent register, is if patent is grants more than two years after the application was filed.

In order to request pay of the renewal fee, the patentee must provide the appropriate patent number, the date of the patent, and the year for which the renewal price is being paid.
