What are Requirements for a Renewal/Annuity application in Vietnam?

In order to renew an industrial design, patent & trademark registration, a renewal/annuity application, with prescribed renewal/annuity fee, must be filed within 6 months before the expiration date of the patent/registration. However, late payment of renewal fees/annuities is available within a six months grace period with surcharge of 10% of maintenance fee (maintenance fee is VND100.000 per class of goods/services (for trademark), per independent claim (for patent), or per embodiment (for design)) for each month overdue.

Required documents

  • A Power of Attorney or an instruction letter (required at the time of filing);
  • The original industrial design, patent or trademark registration, if endorsement on registration is required by the holder (required at the time of filing).


  • For all applications including applications for utility solution, patent, trademark and industrial design, the Applicant just needs to fill in and sign the Power of Attorney form. The IP Vietnam does not require notarization nor legalization.
  • The IP Vietnam does allow late submission of Power of Attorney with surcharge, but can not be later than 1 month from the filing date.
