Zippo Manufacturing Co. v. Zippo Dot Com, Inc.
U.S. District Court ruling establishing the Zippo "Sliding Scale" test

Zippo Manufacturing Co. v. Zippo Dot Com, Inc., 952 F. Supp. 1119 (W.D. Pa. 1997), was a decision by the United States District Court for the Western District of Pennsylvania holding that a court has personal jurisdiction over a website originating in a different territory, if the website is accessible to Internet users in the court's territory.
Zippo is a landmark opinion regarding personal jurisdiction for courts deciding Internet-oriented disputes, and it is one of the most frequently cited Internet law precedents. The case established a standard of jurisdictional analysis now known as the "Zippo test," or the "Zippo sliding scale test."
Background
Zippo Manufacturing Company, a Pennsylvania corporation, makes the well-known Zippo pocket lighters. Zippo.com was an unaffiliated California corporation that operated an Internet website offering access to USENET newsgroups. The Zippo.com company registered the domain names "zippo.com", "zippo.net", and "zipponews.com" without regard for the prior use of that name by the lighter company.
Zippo Manufacturing filed a complaint in its own Pennsylvania district court against Zippo.com, alleging trademark dilution, trademark infringement, and false designation under the Lanham Act and state trademark dilution statutes.
