Thailand operates a first-to-file system: the first applicant generally prevails, regardless of prior use abroad. Filing early is the most effective defence against squatters.
Applications are classified under the Nice Agreement and examined for distinctiveness and conflicts. Thailand also accepts international applications through the Madrid Protocol.
