From August 2025, the Thai Trade mark Office (TMO) has updated its process for issuing certificates for international trade mark registrations  (“IR”) designating Thailand. This change affects how trade mark owners receive proof of registration.

Key Points:

• Electronic Certificates: For IRs filed through WIPO, no physical hardcopy will be issued. The electronic certificate serves as the official record and includes a QR Code at the bottom of the certificate for verification purpose. 

Example: Thai TMO’s electronic certificate and verification page

• National Applications: For national trade marks filed in Thailand, the TMO will continue to issue physical hardcopy certificates (no change). Certificates are sent to the trade mark owner or the local representative’s address in Thailand. Hardcopy certificates remain necessary for certain transactions, such as assignments.

Implications:

This update simplifies international trade mark management and ensures faster, paperless processing through WIPO. This electronic certificate carries the same legal effect as the original hardcopy, including for enforcement purposes.

For assistance with renewals, recordals, or assignments, our Trade Mark and Brands Team at Rouse is available to provide guidance and support.
