Registering a Trademark in Thailand

Registering a trademark is a very important step in protecting the intellectual property belonging to a company or inventor, and there are essential benefits in doing so. Apart from protecting your company’s rights, it also helps you make sure that you are not unknowingly using a trademark that already belongs to another company or person. Registering also guarantees that the rights of property will be respected and most likely not infringed, as our Thai lawyers counsel.

Conditions for trademark registration in Thailand
Trademarks in Thailand are categorized according to the International Classification for Goods and Services, and consequently there are 34 classes of goods and 11 classes into which services are included. The trademark must be a mark such as a word, phrase, logo, image, combination of colors, photograph or design that represents a symbol of the company’s visual identity and thus it must be legally safeguarded.
Trademarks registered abroad are not automatically protected in Thailand (protection requires a Thai filing or, since 7 November 2017, an international registration under the Madrid Protocol designating Thailand), and Thailand has no other treaties of mutual recognition and enforcement with respect to trademarks usage.
If the company has its headquarters in Thailand, it can freely apply for registration. In case it is a non-resident one, a Thai agent must be chosen and he will be given the legal rights in order to deal with this matter. After the application is submitted, the Trademark Register at the Ministry of Commerce will consider it and verify that it meets all the stipulated requirements, according to the Thailand law.
The mark must not resemble any other existing trademarks in any way, it must be a sign that is easily recognizable by the general public, and it must also be in direct connection with the goods or services provided by the respective company.

Renewal of a trademark in Thailand
Our Thai lawyers underline the fact that state arms or crests, official emblems, monarchy seals and those of ministries, together with national or official flags are listed among the items that can never constitute a trademark.
The duration of a trademark in Thailand is of ten years from the date it has been registered. After its validity has expired, the trademark renewal will be granted if the company applying or the agent that represents it submits an application 90 days before the expiration date.

Changing the trademark registration information
In some situations, individuals who register a trademark in Thailand may need to change the information provided or make mandatory corrections. This can be done while the trademark is still under analysis (taken under consideration for approval) or for one that has already been registered. Some examples include the following:
- changing the goods that are used under the trademark (can include only the cancellation of some of the goods that will or are currently used under the chosen mark);
- changing the name, the address and/or occupation of the trademark owner as well as those of the agent (or attorney, as applicable);
- canceling the appointment of the agent or attorney;
- changing the address of the office in Thailand or the point of contact in the country;
- changes in the applicant’s nationality or address;
- changes in the pictures submitted as part of the trademark (the picture for the non-essential part of the mark).
The experts at our Thai law firm can provide more details on these situations and the laws that describe them in more detail (for example, the Trademark Act Section 52 and the relevant Ministerial Regulations).

If the applicant cannot notify the authorities himself immediately, then the official who handles the application will duly note the changes that need to be made and the applicant will be noticed thereof, having the ability to make the corrections and the submissions within 90 days from the date the application to register a trademark in Thailand was submitted.
How to register the distinctive trademark in Thailand
The Department of Intellectual Property in Thailand can analyze your trademark before the registration, to see if it’s distinctive or not. Besides that, any businessman in Thailand needs to know that royal seals, flags or emblems related to the country will not be taken into consideration when registering the trademark for the enterprise. Thailand uses the international (Nice) classification system with 45 classes of goods and services and particular conditions need to be measured when registering the trademark:
• the person who wishes to register the trademark needs to present the signature and the product;
• the applicant must offer proper information about the name and the color arrangement of the product he wants to introduce on the Thai market;
• it is recommended to avoid the attributes which refer to the quality of the products;
• the company’s documents need to be prepared.
The Commerce Registrar in Thailand deals with the registration of the distinctive trademarks in the country, no matter the type of business a person chooses. The approval is usually received within 12-18 months from the date of the application, but with the guarantee the trademark will be protected all this time.

Trademark infringement and enforcement in Thailand
The action of using a trademark without permission, generally in relation to services or products, can create a confused situation about who is the provider of the services. This specific situation is known as trademark infringement and it makes possible for individuals to believe a product or service is associated with a different company than the one which is actually providing it.
Trademark infringement in Thailand is a commonly used action across the business sector in this country. This affects a wide range of services, such as: pharmaceuticals, cosmetics, food and beverages, electronics, luxury items, furnishing, hospitality, logistics, technology, etc. In this case, protecting the intellectual property of an entity in Thailand is a must through the process of registering a Thai trademark.
Registered trademarks in Thailand benefit from specific legal aspects that act like safeguards and protects them under the laws imposed by The Trademark Act. Although Thai legislation permits the enforcement of both registered and unregistered trademarks in Thailand, the unregistered ones are only regulated by the Penal or Civil Code in Thailand, making them more fragile to infringements.
