be presumed to know something” about the art “apart from what
the references disclose.” In re Jacoby, 309 F.2d 513, 516,
135 USPQ 317, 319 (CCPA 1962). With this principle in mind,
we consider the examiner's rejection and the appellant's
arguments.
The examiner makes the following rejection.
Kuo, suggests that the bit line precharging
apparatus (13), in responsive to control lines (14)
from a control logic (15), precharges bit lines BL
and BL* to high or low logic states .... Such bit
lines BL and BL* are a complementary pair of bit
lines. In addition, Kuo's precharging apparatus not
only can supply a high voltage to the complementary
pair of bit lines, but also can supply a low voltage
to the complementary pair of bit lines. Such a
precharging apparatus would disable a (ie. Low)
voltage and supply another (ie. High) voltage to the
bit line pair. This is because the precharging
apparatus (13), in responsive [sic] to the control
lines, has capability [sic] for alternating the
voltage (to high or low states ...) on the
complementary pair of bit lines.
(Examiner's Answer at 8-9.) The appellant makes two
arguments. First, he argues, "Kuo et al. has no teachings or
suggestions of precharging the complementary pairs of
bitlines. Kuo et al. precharges only one bitline." (Appeal
Br. at 4.)
