Have you looked at the patents in question? Here they are: [1] [2] [3] [4] [5]. 1,2,4, and 5 are absurdly broad, obvious, almost certainly were preceded by basic networking functions, and should not have been granted in the first place. The third is possibly novel so I'll grant them that. This whole case is a great example of the ridiculousness of software patents in the modern USPTO system.
