2. Trademark in Vietnam – basic things to know

A trademark, as provided under Article 4.16, Vietnam IP Law, is defined as a sign used to distinguish goods or services of different organizations or individuals. Trademarks under the laws of Vietnam can be categorized in five types as follows:

(i). Trademark including service mark means any sign used to distinguish goods and/or services of different organizations or individuals (Article 4.16, Vietnam IP Law).

(ii). Collective mark means a mark used to distinguish goods and/or services of members from those of non-members of an organization which is the owner of such mark (Article 4.17, Vietnam IP Law).

(iii). Certification mark means a mark which is authorized by its owner to be used by another organization or individual on the latter’s goods and/or services, for the purpose of certifying the origin, raw materials, materials, mode of manufacture of goods or manner of provision of services, quality, accuracy, safety or other characteristics of goods and/or services bearing the mark (Article 4.18, Vietnam IP Law).

(iv). Associated mark means identical or similar marks registered by the same entity and intended for use on products or services which are of the same type or similar types or interrelated (Article 4.19, Vietnam IP Law).

(v). Well-known mark: means a mark widely known by consumers throughout the Vietnamese territory (Article 4.20, Vietnam IP Law).

For trademarks to be eligible for protection in Vietnam, they must meet the following requirements:

(i). To be visible signs in the form of letters, words, drawings or images including holograms, or a combination thereof, represented in one or more colours, and

(ii). To be capable of distinguishing goods or services of the mark owner from those of other subjects as provided under Article 72, Vietnam IP Law. A mark is distinctive if it consists of one or more easily noticeable and memorable elements, or of many elements forming an easily noticeable and memorable combination. Three-dimensional signs (shapes) can be registered as trademarks under the laws and practice in Vietnam.

Thus, the unconventional trademarks based on sound and smell which are not visible are not yet recognised.

Trademark rights are established on ground of a decision issued by the IP Office of Vietnam on trademark registration or protection in Vietnam (with an exception of well-known trademarks where trademark rights can be established on use) as provided per Article 6.3(a) of the IP Law 2005. Vietnam’s trademark regime operates on a first-to-file basis, protection for unregistered trademarks is only granted in limited cases (e.g. an unregistered trademark in Vietnam is enforceable when (i) it is recognized as a well-known mark in Vietnam under Article 4.20 and Article 75 of the IP Law of Vietnam or (ii) it is falls within the scope of “unfair competition” under Article 130 of the IP Law of Vietnam).

3. Establishment of industrial property rights to trademarks in Vietnam

3.1. Right to register trademark in Vietnam

In general, an entity or individual shall be entitled to file an application for a trademark to be used for the goods or services produced or supplied by such entity or individual. Vietnam adopts the first-to-file principle, which grants exclusive trademark rights to the first party that applies for registration of the mark.

An entity or individual legally engaged in the trade of a product manufactured by a third party shall be entitled to file an application for a mark to be used for such product, provided that the manufacturer neither uses such mark for the product nor objects to such filing. This right-to-file principle serves as a ground for initiating a trademark opposition and/or trademark cancellation in Vietnam in case a third party files or registers a trademark of a legitimate owner on bad faith.

3.2 Methods of filing an application for registration of establishment of industrial property rights to inventions

Trademark can be protected in Vietnam by filing an application for registration directly with the IP Office of Vietnam or by filing an International Application under Madrid system.

The application for a mark registration must be filed directly or by mail, to the IP Office of Vietnam or its brand offices in Ho Chi Minh City or Da Nang:

Foreign applicants can obtain a mark registration in Viet Nam by filing an international application with the International Bureau of the World Intellectual Property Organization (WIPO) which designates Viet Nam through the Madrid Agreement or the Madrid Protocol or both of them.

3.3. First-to-file principle

Vietnam operates under a ‘first-to-file’ system. Hence, it is important to register trademarks in Vietnam as early as possible. In such respect, monopoly trademark-based rights are conferred to the person who is the first to file a trademark application for registration thereof. If there are 2 or more applications for registration of the same mark, for the same goods and/or services, under the same priority conditions, all of the applicants are required to reach an agreement to proceed with one application only. Without such an agreement, all those applications shall be refused. In addition, in case there are several applications filed by the same person for identical trademarks for identical goods/services, a trademark registration may only be granted for a trademark claimed in a valid application having the earliest date of priority or filing date among the applications that satisfy all the conditions for registration.

3.4. Priority principle

Per Article 90 of Vietnam IP Law, trademark applicants for subsequent trademark application are allowed to claim priority derived from the first application for the same subject matter filed in Vietnam or a member country of an international treaty having provisions on priority rights, to which the Socialist Republic of Vietnam is a party, or a country having agreed with Vietnam to apply such provisions, provided that the applicant is a national of Vietnam or such a member country.

As Vietnam is party to the Paris Convention for the Protection of Industrial Property (“Paris Convention”), applicants for trademark registration are entitled to a ‘right of priority’ if the same filing has been made within the last six (6) months in any other country which is also a party to the Paris Convention.

For trademark filing in Vietnam to claim priority based on Paris Convention, the applicant is required to submit a certified copy of priority document for claiming priority right under the Paris Convention (if any) (priority data are acceptable at filing, provided that the certified copy is submitted within 3 months from the filing date).

  1. List of goods/services - Must be clear to specify the goods and services.

As of 1 October 2017, the NOIP has acceded to the 11th edition of International Classification for Goods and Services.
  2. A trademark application can cover more than 01 class. The priority right belongs to the person who first files application for trademark registration, it is advised to file application for trademark registration as soon as possible.
  3. The time limit from the filing to granting date is 12 months, of which 01 month is for formality examination, 02 months are for data preparation for publication of the application and 09 months are for substantive examination and publication of trademark application;
  4. The protection title of a trademark is a Trademark Registration Certificate, which is effective from the granting date;

  6. A Trademark Registration Certificate can be suspended by a request made by any third party if it is not used in five successive years without any proper reason.

  8. To assist clients, during the examination of the trademark application, we do not charge fees for sending Notification of Formality Examination, Notification of Substantive Examination as well as translating those Notifications from Vietnamese into English.

Under Law on Intellectual Property of Vietnam, a trademark application must undergo 02 phases of examination, i.e., formality examination (or examination as to form) and substantive examination (or examination as to substance).

Before the expiration of the time limit above, the IP Office of Vietnam shall complete the formality examination of applications and send notices on examination results to applicants.

The substantive examination aims at appraising whether the mark is available for registration and use in connection with the applied goods/services. However, in practice, the time for two phases is often prolonged and in most cases, it takes 12-15 months for a trademark to be registered. The time may be longer if the trademark application is required to be amended or the mark is opposed or provisionally refused.
