that the switch interface has a distinct and separate
composition from the bus of the node. However, the Examiner
contends:
The switch interface coupled to the
crossbar switch in Hedberg et al using fiber optic
connections would have a composition distinct and
separate from the bus interface coupled to the host
computer using cable connections. Hence, the switch
interface would have a composition distinct and
separate from the bus of the
host computer, even under the circumstance that the
composition of the bus of the host computer is made
identical to the composition of the bus interface
coupled to it. (Answer-pages 5 and 6.)3
Appellants argue “The present invention is a
hardware approach that is easy to implement and does not
require processor control and special software as Hedberg does
(see col. 5, line 10 of Hedberg).” (Brief-page 5.)
This argument fails at the outset because it is not
based on limitations appearing in the claims. Thus, Hedberg’s
argued use of processor control and special software are

Hedberg, column 4, lines 17 and 18.
