How to claim trademark priority？
A trademark applicant that has been filed in a country mutually recognizing priority with Taiwan, may claim priority within six months following the filing date of which the trademark application was first filed in the given country.
In addition, the applicant shall submit, within three months from the date following the filing of the trademark application in the ROC, a certified copy of the basic application as accepted by the government of the particular foreign country in order not to forfeit the priority right.（§20, Trademark Act）
Since our accession to the WTO on January 1, 2002, all member states of the WTO are entitled to claim priority in Taiwan.
