As a member of WTO, Taiwan had been gradually revising related laws and regulations in order to comply with the TRIPS Agreement’s requirement regarding to the protection of geographic indications. In the last year, the Trademark Law had been amended by adding “Geographical Certification Mark” and ” Geographical Collective Trademark” in order to strengthen our protection on geographical indications. However, under the amended law, as long as the mark referring goods or services from that geographical region shall have a given quality, reputation or other characteristic, even if the mark consisting exclusively of a description of the quality, intended purpose, material, place of origin, or relevant characteristics of the designated goods or services, which can still obtain the registration as a geographical certification mark or geographical collective trademark. By granting such registration, the right of a third party from indicating place of origin in relation to its own goods or services in accordance with honest practices in commercial matters is jeopardized. The purpose of this thesis is to explore the issues concerning the registration of geographical indications and trademark fair use by reviewing the case of “Chihshang Rice”, “Mato Buntan” and “Sanuki Udon”.
