In Taiwan, it is no longer necessary to file with the IP Office an original certified copy of the corresponding foreign application in support of a priority claim for a trademark application. In other words, a photocopy of the certified copy would be sufficient.
The above practice change was introduced into Article 4 of the amended Enforcement Rules of Trademark Law implemented since July 13, 2015. However, whenever the IP Office considers there is a need to verify the authenticity of a photocopied document filed, the IP Office may still require the applicant to submit an original certified copy to determine if the applicant is indeed entitled to the right of priority.
