VN.02 PRIORITY DOCUMENT (TRANSLATION)
PCT Rule 17.2(a), C 23(6)
The Office will require the applicant to furnish a certified translation of the priority document only in certain cases where required for examination.

VN.03 FEES (MANNER OF PAYMENT)
The manner of payment of the fees indicated in the Summary and in this Chapter is outlined in Annex VN.I.
VN.04 REQUEST FOR EXAMINATION
GD Sec. 18(3), C 15(1)
A patent may be granted only after the substantive examination, which may be requested by the applicant or by a third party. The request must be made in writing within 42 months from the priority date in case of an applica-tion for a patent for invention or 36 months from the priority date in case of an application for a patent for utility solution. The request for examination is only effective if the fee for requesting examination has been paid. The amount of the said fee is indicated in Annex VN.I.
VN.05 REPRESENTATION
GD Sec. 15(3)(b)
An applicant having no habitual residence, headquarters or representative office in Viet Nam must be represented by an attorney authorized to act by the competent authority of the State. A list of registered attorneys is available upon request from the Office.
VN.06 AMENDMENT OF THE APPLICATION; TIME LIMITS
PCT Art. 28, PCT Art. 41
The applicant may amend or correct the international application up to the grant of the patent, provided the scope of the subject matter is not broadened thereby.

After a patent has been granted, annual fees must be paid for maintaining the patent in force. The first annual fee must be paid within a time limit which shall be fixed in the notification of the grant of the patent. Payment of annual fees for each succeeding year must be made within the last six months of the previous year. If an annual fee is paid later than during this period, the patentee shall be required to pay a supplementary fee amounting to 10% of the annual fee for each month overdue. In the absence of justifiable grounds for delay, failure to pay an annual fee within six months from the last day of the period during which it is due will render the patent invalid.

PCT Rule 49bis.1(a), PCT Rule 76.5, GD Sec. 9(2)(b)
The requirements for the national phase are basically the same as for an application for a patent for invention. A patent for utility solution has a term of 10 years from the filing date.

VN.12 CONVERSION
GD Sec. 13
An international application for a patent for invention filed with the Office may, at the request of the applicant and upon payment of the prescribed fee for requesting conversion, be converted into an application for a patent for utility solution after the substantive examination of the application for a patent for invention has taken place, if the requirements for granting the patent are found not to be fulfilled and if such request for conversion is filed within three months from the date of notification of refusal of the grant of the patent for invention.
