US Federal Circuit unanimously affirmed U.S. District Judge James V. Selna’s ruling confirming the unpatentability and invalidity of Essociate’s patent.
Last February, Crakmedia won the first round of a hard-fought patent battle filed by Essociate, Inc. Essociate claimed Crakmedia was infringing on their patent, U.S. Patent No. 6,804,660. Their patent described a method and system for configuring an existing affiliate network to receive “virtual affiliates” from an affiliate pooling network. Essociate has used its patent to sue more than 20 companies in the affiliate networking space for infringing on the ‘660 patent.
