Trademark Registration Procedure in Vietnam
The application is filed at the Intellectual Property Office of Vietnam (IP Vietnam).
The application for trademark registration will undergo following steps: a formality examination will be done within one month from the date of receiving required documents. If the application is accepted as to the formalities, the application data will be published in the Official Gazette of Industrial Property. This shall be done within two months from the date of acceptance as to formality. Within the following 9-12 months, the application will undergo a substantive examination as to make a decision of refusal or grant of the protection by the trademark office. During this time, any third party may file an official opposition. After grant of Trademark Registration Certificate, the mark shall be published in the gazette and recorded in the National Register of Industrial Property.
National Opposition Period
Applications may be opposed at any time after the publication date and before issuance of the registration certificate.
The time for completion of registration: if there is no obstacle arises during the process of examination, in principle, the time from filing an application to registration is 12 months under the IP Law. However, in practice, this period is routinely prolonged from 18-20 months as the substantive backlogs at the Registry. On average, the time frame for obtaining trademark registration in smooth cases is approx. 18-20 months from the date of filing. However, the actual time for substantive examination is 18-24 months. So the time for obtaining trademark registration in smooth cases is approx. 21-27 months from the date of filing.
