We turn to appellants’ argument to determine if anything therein persuades us of an error in the examiner’s case. With regard to independent claim 1, appellants argue that the tree topologies comprising the claimed switches include both wireless and fixed networks. In fact, a substantial part of appellants’ argument is that the instant invention is directed to including both wireless and fixed networks and that Katzela does not disclose or suggest forming tree topologies in an ATM network using both wireless and fixed terminals. Appellants contend that Katzela merely discloses a method for updating a tree topology in order to handle network traffic and conditions in a wireless only communications network. Note pages 3-5 of the principal brief. This argument is not persuasive because it is not based on any particular claimed limitation. Neither independent claim 1, nor any of the other claims on appeal, is limited to forming tree topologies including “both wireless and fixed” networks. Arguments regarding “both wireless and fixed” networks fail from the outset since they 5Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 NextLast modified: November 3, 2007
