one of the common disk drive ports such that the common disk
drivers may initialize while only one port is logically
connected, maintaining an acyclic star configuration without
creating loops. See page 5 of Appellants' brief.
In response, the Examiner argues on pages 3 and 4 of the
answer that IEEE teaches that redundant paths are a good
thing. The Examiner states that it would have been therefore
motivating to one of ordinary skill in the art to create more
than one path to the devices for reliability purposes. The
Examiner then states that the duplicating of the paths would
include duplicating the concentrator.
Upon our review of IEEE, we fail to find any teaching or
suggestion of a high speed acyclic serial bus in which there
are
"complementary first and second signals, said first
signal being used to activate said first enabling
means and said complementary second signal being
used to activate said second enabling means such
that each of the plurality devices is only accessed
by one concentrator"
as recited in Appellants' claim 1. Furthermore, we fail to
find that Van Brunt or Oprescu suggests or teaches the
complementary signals which may be utilized to selectively
