Appeal No. 2006-1839
Application 10/071,379
Ohkubo. It appears that the prior art showings in figures 2 and 3 of this reference
correlate somewhat to appellants’ prior art figures and the specification as filed to the
extent that the shields G and V in these figures teach and show the use of shields with
respect to a signal line F. The reference also shows that signal drivers B drive the signal
line.
Ohkubo’s contribution to the art is, as noted by the examiner in the answer, shown
in figures 5, 10 and 11 in the various embodiments there, which respectively relate to
Ohkubo’s interference preventing section or circuitry. The interference preventing
circuitry in figure 5 is basically the NAND circuits W whereas in figure 10 it is the
logical NOR and inverter circuits W and in figure 11 it is the XOR circuit W. In any of
these embodiments Ohkubo’s circuits operate in such a manner that they are switched in
the same phase as the input signal supplied to a specific signal wiring line. This is shown
in figures 6 and 7, for example. The brief characterizes this at pages 9 and 10 such that
the shield wires S in these figures transition with the respective signal lines F. At least in
this respect, we agree with appellants’ observation at the top of page 10 of the principal
brief on appeal that this reference does not contain interference prevention circuitry
which functions after a transition of a signal line as required by independent claim 1 on
appeal, for example.
