A ruling that has received wide public attention in the United States, even in the popular press, is the one that the Court of Appeals for the Federal Circuit (CAFC) handed down on February 14 2001 in Amazon.com Inc v Barnesandnoble.com Inc. This ruling vacated a district court's preliminary injunction order preventing Barnes and Noble (BN) from continuing to offer its own so-called "one-click" method for ordering books and other goods online during the course of Amazon's suit asserting that the BN method infringes an Amazon method patent. Despite all the publicity accorded to the ruling, it rests upon very well-established law, widely availed of to defeat preliminary injunction motions in patent infringement suits throughout at least the twentieth century. Its claim to the degree of publicity it received rests upon the case's status as one of the earliest efforts to enforce a "business method" patent against an alleged infringer and not upon the novelty of the legal ruling.
