An application can be filed in English, French or Spanish at the applicant`s choice. The application contains one or more views of the designs concerned and may contain up to 100 different designs, provided that all designs belong to the same class of the international classification of industrial designs (Locarno classification). Two acts of the Hague Convention are currently in force – the 1999 Act and the 1960 Act. In September 2009, it was decided to freeze the application of the 1934 Hague Convention Act, simplifying and streamlining the overall management of the international design registration system. A description is required. Vietnam made the statement under Article 5, paragraph 2, point a), of the 1999 Act, which states that an international request that characterizes Vietnam contains, in accordance with Article 5, paragraph 2, point b) (ii), a brief description of the characteristics of the design. The International Office of WIPO provides the Office of Mental Protection Procedures with a copy of the international registration and any relevant information, document or model attached to the international application under Article 10, paragraph 5, point a). The Hague system ensures the protection of industrial design in several jurisdictions through a single application filed with the International Office of the World Intellectual Property Organization (WIPO). The primary objective of the Hague system is to streamline the process of obtaining several industrial-type certificates in the world by requiring a single application with a single payment in a single currency. An industrial design is not considered irreversible if it has been published in the following circumstances, provided that the application for registration of industrial designs is filed within six months of the date of publication: c) it was issued at a national exhibition in Vietnam or an official or officially recognized international exhibition by the person who has the right to be registered in accordance with Article 86 of the law. However, the Vietnam Intellectual Property Office (IP Office) may dismiss the application as insufficient to ensure that industrial design is not fully disclosed in accordance with Rule 9 (4) if no other opinions are presented, in particular six orthogonal views (before, above, above, right and left).
