Amazon.com, Inc. v. Barnesandnoble.com, Inc.
United States Court of Appeals for the Federal Circuit
239 F.3d. 1343 (2001)
Relevant factsFree
Amazon (plaintiff) obtained a preliminary injunction against Barnes & Noble (defendant) for allegedly infringing its one-click ordering patent, but BN presented prior-art evidence — including the CompuServe Trend system and the Web Basket cookie-based ordering system — suggesting the underlying technology already existed in the public domain before Amazon's patent issued.
IssueFree
Whether the existence of prior art that either anticipates a patent's claims or renders them obvious raises substantial questions about the patent's validity.
