    As to all patent applications to be filed in Vietnam, the Vietnamese version of the specification is required right at the filing time. Thus, instruction letter and English specification need to be provided as soon as possible (preferably 03 months before filing deadline) for translation work;

  5. Valid patent applications are published in the 19th month computed from priority date or Vietnamese filing date (if no priority is claimed), or within 02 months computed from the date of official acceptance of applications, depending on which date comes later. Thus, for the examination process to be shortened, it is advised that a request of early publication should be made. Then, the fee for the request of early publication will be incurred;
