New Zealand Patent Renewals

The first renewal fee payment for a Standard New Zealand patent  generally falls due before the 4th anniversary of the date of filing of the Complete Specification.  If this date precedes sealing of the patent, the due date is four (4) months after the date of sealing.  Renewal fees are then due before the 7th, 10th and 13th anniversaries of the Complete Application filing date.  The term of the patent is twenty (20) years from the date of filing of the Complete Specification.

The time for renewing a Divisional Application stems from the date of filing of the "parent"  or "grandparent" application, or the first application in the preceding chain of applications. 

No renewal fee is payable in respect of a Patent of Addition, which automatically remains in force for the remaining term of its parent.  The status of the parent case will affect the Patent of Addition.  A Patent of Addition can therefore become an independent patent and renewal fees fall due when the parent fees would have fallen due.

A grace period of six (6) months is provided for late payment of renewal fees.
