New Trademark Examination Manual Effective
The Thai Department of Intellectual Property (DIP) published its final Trademark Examination Manual, which provides guidance to examiners on trademark examination in the areas where the Trademark Law leaves it to them.

It became effective from January 17, 2022, onwards with all pending and newly filed trademark applications.

The Examination Manual contains eight sections on the trademark examination procedure, starting with the formal examination of the trademark application, the issuance of the office action, the publication of the trademark, and ending with the trademark opposition. Some of the most important changes in examination practice on the issue of distinctiveness.

The Examination Manual is expected to be followed and complied with by all Thai trademark registrars, but it is not legally binding on registrars.

New Trademark Bill Approved
A Draft Trade Mark Bill was approved by the Cabinet in Thailand on November 22, 2011, and the approved version was submitted to the Parliament for its final consideration and approval. It is expected to come into force in June 2012.

The Bill contains several significant points, which the Department of Intellectual Property believes will expand the scope of trade mark protection in Thailand, and accelerate and facilitate the registration process, and provide for more suitable fees for registration.

Under the Bill, “scent and sound” have been included in the definition of the term "mark" in order to extend the scope of protection to these non-traditional trade mark forms.

The Bill also provides clearer and more specific criteria for the purpose of determining whether a mark is distinctive. A distinctive status is ascribed to an invented word, invented number, or invented character. They can therefore be registered as trademarks.

The Bill also provides that a shape mark has a distinctive status, if the shape of the mark does not indicate the nature of the goods, or obtain technical results, or give substantial value to the goods.

Moreover, the Bill provides that if a trade mark is not inherently distinctive, as provided by law, it can acquire distinctive status by way of acquiring a secondary meaning - that is, by proving that the mark has been used in association with the applicant's goods or services in a commercial sense, and through such usage, has become well known in Thailand. The trade mark will thereby become distinctive.

Legal basis for trademark protection in Thailand is the Trademark Act B.E. 2534 (A.D. 1991) effective February 14, 1992 as amended by the Trademark Act (No. 2) B.E. 2543 (A.D. 2000) effective July 1, 2000 and the Trademark Act (No. 3) B.E. 2559 (A.D. 2016) effective July 28, 2016 and the ministerial regulations and notices issued by the Ministry of Commerce and the Department of Intellectual Property under the Trademark Act.
Section 272 of the Criminal Code provides criminal sanctions for the offence of passing-off. Meanwhile, Sections 273 and 274 provide protection for trademarks registered in foreign countries.

Thailand is a member of the Madrid Protocol, effective from 7 November 2017.
Thailand is not a party to the Nice Agreement. However, the Trademark Office adopts the Nice Classification (12th Edition) as guideline in examining the specification of goods and services. Certain kinds of goods and services under the Nice Classification are not acceptable to the Trademark Registrar and needed to be specified with more specific items of goods and services. Class headings or broad terms are not allowed.
“Mark” means a photograph, drawing, device, brand, name, word, statement, letter, numeral, signature, combination of colors, shape or configuration of an object, sound or any combination thereof. To be registrable, a trademark must (1) be distinctive; (2) not be prohibited by law; and (3) not be the same as or similar to a trademark registered by another person.
The following trademark types are registrable: trade marks, service marks, collective marks and certification marks.
A trademark application can be filed at the Trademark Office or filed online through the Department of Intellectual Property.
Multiple-class applications are possible. (A multiple-class application is not allowed to be split into various single-class applications but the applicant is allowed to remove the certain class(es) of goods/services from the application.)
Foreign applicants need a local agent for filing a local application.
A notarised power of attorney is necessary. Legalization is not required.
The application process includes a formal examination, a search for prior trademarks and an examination of distinctiveness.
The Trademark Examination Manual, which was revised on January 17, 2022, serves as a guide for examiners on trademark examination.
To be registrable, a trademark must be distinctive, not prohibited, and not identical with or confusingly similar to other registered Trademarks. Marks not deemed distinctive in the examination can be registered if distinctiveness has been acquired by use. If the mark is rejected for lack of distinctiveness, the applicant can file an appeal with the Trademark Board.
A straightforward application takes between 18 to 24 months to reach registration. The processing time from the filing date to first office action is around 12-18 months.
Prior to registration, the trademark application is published in the “Trademarks Journal” for opposition.
The opposition period is 60 days from the publication date of the application. The Trademark Office takes at least 18-24 months to issue its decision in relation to the opposition.

Details regarding the Opposition Period against designation of IR Mark are available in our publication on this topic here
A trademark registration is valid for 10 years from the application date. The registration is renewable for periods of 10 years each.
Practical details on grace periods for trademark renewals are available in our publication here
Practical details on trademark use requirements are available in our publication here
The official fees for filing a trademark application and registration of a trademark that covers not more than 5 items of goods or services in a class are calculated based on the number of items. On the other hand, if the designated goods/services in any class are more than 5 items, the said official fees are payable at a flat rates, instead of the rate on 'per item basis' (not in addition to the 'per item' rate).

The official fee for filing a trademark application is THB 1,000 per item of up to five items in a class.
The official fee for filing a trademark application with more than 5 items in a class is at the flat rate of THB 9,000.
The official registration fee is THB 600 per item of up to five items in a class.
The official registration fee with more than 5 items in a class is at the flat rate of THB 5,400.
There is no publication fee.
