STM), and Isono deals strictly with ATM (out-of-band)
networks. Thus, Appellants argue, there is no motivation
taught or suggested to interface an ATM switch/network with an
STM switch/network. The only such teaching resides in
Appellants’ own specification. (Brief-pages 4 and 5.)
We note that Fuller is looking to provide new
services to users, such as ISDN. Fuller states “The invention
also allows users to provide new revenue generating services
(such as ISDN) which require SS7 capabilities.” (Column 2,
lines 47-49.) Isono discloses increasing need for multimedia
communication using ISDN based on ATM (column 6, lines 30-38).
Thus we agree with the Examiner that it would have been
obvious to adapt SS7, which uses out-of-band signaling, to
ATM, also using out-of-band signaling, to provide broad band
ISDN, contemplated by Fuller, via ATM networks. Appellants
also acknowledge the need to adapt STM to ATM as recognized in
the art, wherein their specification states:
It is also unlikely that a telecommunications
carrier (LEC or IXC) will replace its entire STM
network at once with a B-ISDN/ATM network, but will
more likely migrate toward that end in stages such
that during intermediate stages of the conversion a
