Trademark in Thailand

A trademark is a distinct mark, accorded to goods and/or services, as an indicator of a proprietorship, business, or individual, in order to establish the identification of the same and create a difference between other goods and/or services of the same kind, from other competing entities/businesses.

Trademarks in Thailand may be designated by the following symbols:

  • ™ (for an unregistered trademark, but for which application has been filed)
  • ℠ (for an unregistered service mark, but for which application has been filed)
  • ® (for a registered trademark)

Trademark registration in ThailandA trademark can be a sketch, picture, brand name, word, text, letter, numeral, signature, group of colors, shape, figurative element, a three-dimensional representation, or a combination of any of the above, in a creative expression. Further, in a slightly more complicated sense, trademarks may also include distinctions created on the basis of color, smell, or sound, specific to a brand.

On an unsolicited use of a registered trademark, the owner of the same may institute legal proceedings against the infringer, to prevent any further unauthorized use of the trademark. However, for the suit to be instituted or to be successful, the registration of the trademark is not mandatory, albeit preferred. In Thailand, a trademark infringement suit may be instituted against an infringer only on the basis of a mark being well known within the geographical territory of Thailand, and among the general consumer base.

Apart from the external expression grounds mentioned above, which are commonly the instituting basis for trademark applications, there are other identifying features or characteristics, which can be registered as distinct marks, which are specifically related to service imparting.
