High Quality Content by WIKIPEDIA articles! Network Automation, Inc. v. Advanced Systems Concepts, Inc., 638 F.3d 1137 (9th Cir. 2011) was a court case decided on March 8, 2011, where the United States Court of Appeals for the Ninth Circuit found that the use of a competitor`s trademark as an Internet advertisement search keyword did not constitute trademark infringement. In the case, Network Automation advertised their own competing product in search queries that contained Advanced Systems Concepts` "ActiveBatch" trademark. In determining whether trademark infringement occurred, the court evaluated factors relevant to the likelihood of customer confusion outlined in AMF Inc. v. Sleekcraft Boats and concluded that confusion was unlikely.
