SANi, South African and Nigerian patents may be renewed for their entire 20-year term by making a single renewal payment. Doing this reduces the lifetime renewal costs by about 70%:
South African Patent Vicennial Renewal | $285 where the patent was filed by GlobalIPCo / S&Z, else $385 |
Nigerian Patent Vicennial Renewal | $530 where the patent was filed by GlobalIPCo / S&Z |
SANi Patent Vicennial Renewal | $815 |
Irrespective of the number of years a SANi, South African or Nigerian patent has until expiry, all remaining renewals may be pre-paid by making a Vicennial Renewal payment.
To pay a Vicennial Renewal for a South African patent:
The renewal receipt is sent to you by email within a couple of business days, whereafter you won't have to worry about future renewal reminders / payments.
Apart from reducing renewal costs and the risk of the patent lapsing, paying Vicennial Renewals also shields you against future increases in official renewal fees.
