The Intellectual Property Office of Vietnam (IP Viet Nam) is in charge of receiving and examining patent applications. The process for a patent applications begins with filing the patent application with IP Vietnam and finishes with granting a patent, if the related invention is eligible for protection.

Besides, foreign applicants can also obtain a patent right in Vietnam by filing an international application which designates or selects Vietnam through the PCT system. The applicant must carry out procedures for registration of an invention under the PCT’s provisions at IP Vietnam within 31 months from the international filing date or from the priority date, if the priority right is claimed in the application.
Organizations, individuals of Vietnam, foreign individuals permanently residing in Vietnam and foreign organizations and individuals having a production or trading establishment in Vietnam may file applications for a patent either directly or through a lawful representative in Vietnam.
Foreign individuals not permanently residing in Vietnam, foreign organizations and individuals not having a production or trading establishment in Vietnam shall file applications for a patent through a lawful representative in Vietnam.
Vietnam adopts the first-to-file system, i.e. where two or more applications are filed by many different parties for registration of the same invention, the patent may only be granted to the valid application with the earliest priority or filing date among applications that satisfy all required conditions; where there are two or more applications satisfying all the conditions for the grant of patent and having the same earliest priority or filing date, the patent may only be granted to a single application out of these applications under an agreement by all applicants. Without such an agreement, all these applications shall be refused for the grant of a patent.
Accordingly, it is advisable to file an application for a patent as soon as possible after the invention and not to make the invention public before filing the application.
A patent application filed with the IP Vietnam shall be subject to formal examination for evaluating its validity.
The time limit for formality examination of an application is one (1) month from the filing date. In the course of formality examination, if the applicant corrects or supplements documents on his/her own initiative or upon the request of the IP Vietnam, the time limit for formality examination may be prolonged for a period of time during which documents are corrected or supplemented.
Before the expiration of the time limit above, the IP Vietnam shall complete the formality examination of applications and send notices on examination results to applicants.
