•Regarding Trademark Application
It is possible to acquire the right of a trademark written with English letters and their corresponding (homonymous) Thai letters. In this case, the owner of a registered trademark is permitted to enforce the right against the third party who uses a trademark with either English letters or Thai letters. However, in the case where the owner of the registered trademark is accused by the third party in a trial for its cancellation on grounds of non-use in such a situation that the owner has only used the registered trademark written with either English letters or Thai letters, it is uncertain whether or not such use is considered as the use of the whole of the registered trademark. This is because there is no precedent for such a case.
Therefore, if Applicant wishes to use both a trademark written with English letters and a trademark written with Thai letters, Applicant is advised to separately file trademark applications for them.
