Appeal 2007-1047
Application 09/944,892
These multiplex nodes 11 to 17 are interconnected by the
multiplex bus 18 to constitute a network. In this network,
signals representing wheel speeds etc. are transmitted serially in
a multiplex mode.
(Matsuda, col. 3, ll. 63-67).
In particular, we note that Matsuda discloses at least one embodiment
where the multiplex nodes are implemented using dedicated-purpose
computers (see e.g., engine computer 11, anti-lock traction computer 12, and
transmission computer 13, col. 3, ll. 55-59, see also Fig. 1). We note that
Matsuda’s computers operate independently of one another and individually
transmit messages:
The computers 11 to 13 are operated independently of one
another and individually transmit a message shown in FIG. 3 to
the multiplex bus 18 at respective desired timing.
(Matsuda, col. 4, ll. 50-52).
We further note that Matsuda discloses the processing of message
data having the format shown in Figs. 3 and 4 (see also col. 4, l. 53 through
col. 5, l. 27). Thus, we find the weight of the evidence strongly supports the
Examiner’s view that Matsuda’s nodes are intelligent nodes within an
“active network” because each node in the vehicle network may include a
computer that processes message data.
Indeed, when we construe the claim term “active network” in
accordance with Appellants’ proffered “plain meaning,” we find that
Matsuda’s intelligent multiplex nodes are:
