In re Warner, 379 F.2d 1011, 1017, 154 USPQ 173, 178 (CCPA
1967).
Although Ohsawa discloses receiving a signal from line
WRT at respective gate electrodes of data write n-channel MOS
transistors 14 and 15, col. 4, ll. 23-28, the examiner does
not show that the signal is a data signal or that the
transistors are write driver circuits. We address these
defects seriatim.
Rather than being a data signal, the reference suggests
that the signal from line WRT is a control signal. The
examiner admits, “circuits 14-15 of Ohsawa are ON/OFF
controlled in response to a signal from the signal line WRT
....” (Examiner’s Answer at 4.) For its part, the reference
teaches, “[t]he gates of the data write transistors 14 and 15
are connected to a data write control line WRT, and the
transistors 14 and 15 are simultaneously ON/OFF-controlled in
response to a signal from the signal line WRT.” Col. 4, ll.
26-30 (emphasis added). In summary, rather than specifying
data, the WRT signal controls whether transistors 14 and 15
