How do I renew my patent?


Updated by IPOS

You can renew your patent by submitting Patents Form 15 together with the prescribed fee within the prescribed time period. 

The first renewal fee is payable at the end of the fourth year from the date of filing of your patent application.

The life of a patent is 20 years, subject to the payment of annual renewal fees.
