Good to know
- The applicant or its agent must have an office or address for communication with the Registrar in Thailand (Trademark Act, Section 10).
- DIP does not accept Nice class headings or general terms such as "clothing"; specific items must be listed.
- A registered mark is deemed registered as of its application date, and the 10-year term runs from that date (Trademark Act, Sections 42 and 53).
Madrid Protocol and regional systems
Thailand is a member of the Madrid Protocol since 2017-11-07, so an international registration filed through WIPO can designate it.
What Signa holds for Thailand
