Domain name disputes arise increasingly as the Internet spreads over the world. As the highest authority of Internet Domain Name System, ICANN enacted its Uniform Domain Name Dispute Resolution Policy(UDRP) by the end of 1999, which started the procedure of Alternative Dispute Resolution(ADR) on disputes related to Internet domain name, but without legal enforcement effect. To make the rules first included in UDRP enforceable, the U.S. Congress passed a law named “Anticybersquatting Consumer Protection Act” as a prat of “Intellectural Property and Communications Omnibus Reform Act”in Nov. 1999, revising Lanham Act of 1946. A series of statutory rules for the resolution of disputes between domain names and trademarks or personal names were fixed by the law. This article focuses on the “Anticybersquatting Consumer Protection Act”, aims at giving readers an introduction and an academic analysis.
