Second, the examiner asserts that Focsaneanu's "network connection
device (252) device performs protocol conversion (i.e. convert the data packet signal
structure of data signals from one structure to another). . . ." (Examiner's Answer at 4.)
The appellant argues, "performing protocol conversion by controller 252 is not the
equivalent to 'signal processing means that is arranged to convert the signal structure
of data signals, received from a computer via the telecommunication network and the
switch core, to data packets having a signal structure suitable for data communication. .
. .'" (Reply Br. at 5-6.)
As explained regarding the anticipation rejection, independent claims 17 and 18
require converting the signal structure of data signals to data packets having a signal
structure suitable for data communication. For their part, independent claims 1, 14, and
15 specify the same requirement.
Turning to Focsaneanu, although its "controller performs address conversion,
protocol conversion, rerouting etc.," col. 8, ll. 21-22, the controller 252 does not convert
the signal structure of data signals to data packets having a signal structure suitable for
data communication. To the contrary, a separate element "packetizes" data.
Specifically, "packetized data [are] formed at PAD 254 (packet assembly/ disassembly).
. . ." Id. at ll. 22-23.
