''Perfect Web Technologies, Inc. v. InfoUSA, Inc.'' 587 F.3d 1324 (Fed. Cir. Dec. 2, 2009), is a United States Court of Appeals for the Federal Circuit case in which the court held that a patent can be invalidated due to the obvious nature of the asserted claims. Perfect Web, an e-mail marketer, sued its competitor InfoUSA for patent infringement, claiming that InfoUSA's bulk email distribution method infringed its ('400 patent). The district court initially found that the patent did not meet the non-obviousness requirement and was therefore invalid. On appeal, The Federal Court agreed that the patent was obvious because someone of ordinary skill could arrive at the patent claim using common sense.〔 ==Background== Tom DiStefano of Perfect Web Technologies filed his quota-fulfilling bulk email patent, , during the height of the internet tech bubble on April 13, 2000.〔Odom, Gary (Patentlyo Blog: Federal Circuit Affirms Summary Judgment of Obviousness for Bulk EMail Patent ).
