Patent Renewal in India

As per the Indian Patents Act and related rules, in order to keep the patent in force, prescribed renewal fee is required to be paid in respect of each year (3rd year onwards) in advance (i.e before the expiration of the succeeding year) to the Indian Patent Office.

In case the patent is granted later than two years from the date of filing of the application, the renewal fee that becomes due in the meantime has to be paid within three months from the date of recording of the patent.
