How long does it take to authorize an industrial design in Thailand?

The DIP conducts formality examination and substantive examination of the invention patent application. The formality examination generally takes 1-1.5 years. After the completion of the preliminary examination, the patent application will be published and enter a 90-day opposition period. The applicant can only submit a substantive examination request within 5 years after the application is published, and the examination results of other countries such as Japan, the United States, the United Kingdom and Europe need to be provided to the DIP.

DIP only conducts formality examination for utility models, and the documents can be authorized if they meet the formality examination standards. If litigation or evaluation of the stability of utility model Claim is required, the applicant may submit a request for substantive examination within one year after the granted announcement.
