If the patent application is objected due to: (i) certain defects in form, (ii) the subject matter of the invention being statutorily unpatentable, (iii) the applicant not being entitled to file application, or (iv) the application being filed in an improper manner, a Notice of Defect(s) of the application shall be issued by Vietnam Patent Office and the applicant shall be given a 2-month period counted from the date of the Notice in order to correct such defects. Such a set period of time can be extended once for another two months by filing a request for extension of time to Vietnam Patent Office. Such informalities shall not affect the filing date.
The applicant may, at any time prior to the Decision on Refusal or Decision on Grant, make amendments, additions, or divisions to the application, but not beyond the disclosure or so as to change the nature of the invention or industrial design originally claimed; or a fresh application needs to be filed. The amendments may also be made to the name and address of the applicant, the name and nationality of the author(s), the change of the applicant as a result of the assignment of application or inheritance, merger, acquisition or division of legal entities or the like
The examination for patent applications in Vietnam shall be carried out only upon request for examination from either the applicant or a third party, subject to payment of an appropriate fee. Such a request shall be submitted to Vietnam Patent Office within forty two (42) months for inventions, counted from the filing date or the date of priority if the priority is claimed, or the application shall be deemed to have been withdrawn. The time limit for making request for substantive examination of a patent application for utility solution is thirty six (36) months.
Substantive examination is conducted by Vietnam Patent Office in order to determine whether the claimed invention is patentable. The time limit for substantive examination for invention/utility solution applications eighteen (18) months, computed from the publication date of the application if a request for substantive examination is filed prior to the publication date or from the date of receipt of a request for substantive examination if such request is filed after the publication date.
If the patentability requirements are met, or the applicant has properly rectified the deficiencies or successfully rebutted the examiner’s rejection(s), Vietnam Patent Office will issue a “Notification of Intention to Grant” notifying the applicant of its intention to grant a patent, and shall set an three month period of time for the applicant to furnish the IP Vietnam with the required fees for issuance, publication, registrar, and the first annuity
