Under the present legal system of Taiwan, different laws regulate the acquisition and the usage of business names, which including Corporate Law (for corporate name), Businese Registration Law (for parinership, venders), Trade Law (for trading companies) and Trademark Law (for trademarks and service marks). Pursuant to the first-file doctrine, business entities must file applications with relevant authorities, respecivcly, in order to got hold of the desired names. The prevailing of electronic commerce and internet environment, however, have created an additional business name. Even though numerous domain name disputes have make headines in other countries, Taiwan has experienced only one incident, which involves a company use the famous YAHOO! as its domain name in Taiwan. This new challenge, also created various issues, such as who has right to a certain domain name, which business name holder shall prevail in a domain name dispute. Since the Ecommerce is the trend of the future, and Taiwanese enterprises are following this trend closely, the author, therefore, believes more domam name disputes will emerge in Taiwan it the near future. Although many countries give trademark holder the right of priority for the disputed domain name, the author argues that trademark or service mark holder shall not automaticlly prevail over the domain name holder unless certain conditions are met. The author further argues that while waiting for the IAHC final dispute resolution guidelines, authorities can apply the Fair Trade Law, especially the Articles 19, in resolving the disputes. The reason is based on the argument that Article 19 has provided effective dispute resolution mechanism and the Fair Trade Commission has also promulgated regulations which are applicable in domain name disputes. It is reasonable, therefore, to resolve the name disputes through Fair Trade Law mechanism, instead of expanding the jurisdiction of trademark law in Taiwan.
