NetFuel filed its first patent assertion suit this week, targeting F5 with two patents related to computer network management (7,747,730; 8,131,851). The suit accuses F5’s traffic and network management products of infringing the patents. NetFuel incorporated in 2000 and the company’s primary product appears to be its patents, which include the two asserted as well as one pending application. The company’s website, last updated in 2010, advertises its relationships with other companies including Cisco and IBM. 11/4, Northern District of Illinois, 1:13cv07895
