The validity of an invention patent is 20 years, and a utility solution patent is 10 years from the date of filing. The patent’s validity should be maintained annually.
The request for annuity can be filed within 6 months prior to the date of expiry.
The grace period is 6 months from the date of expiry, and the owner(s) must pay the additional fee of 10% of the maintenance fee for each month late. If no annuity is filed before the end of the grace period, the registration will be canceled or deemed expired.
Required documents for request annuity:
1. Full name, address, and nationality of the owner(s).
2. Power of Attorney (POA) signed by the owner(s) (notarization/legalization is not required).
The soft copy of the POA is acceptable at the filing date. The deadline for submitting the original is 1 month from the filing date, non-extendable.
3. Information on Patent(s) number.
4. Original Patent(s) (if the owner wants to record the annuity thereon)
