Appeal No. 96-0230
Application 08/056,094
each of the respective references do not aid us in reaching the
determination of anticipation of claims 1 and 6 on appeal.
Turning lastly to independent claims 11 and 16 on appeal,
each of these claims in some manner recites a means for adjusting
the charging and discharging currents flowing to and from a given
node previously recited in such a manner to optimize slew rate
and overshoot of output driver pulses having selected high and
low voltage levels. These two claims do not recite the
difference determination as a part of the adjusting operation.
Again, even making reference to the portions of the four
references relied upon as pointed out by the examiner at the
bottom of page 2 of the answer, we can find no teaching in the
whole of any of the references for adjusting the charging and
discharging currents in any manner to optimize the slew rates and
overshoots as specified by claims 11 and 16 on appeal. The skew
adjusting circuit 22 in Fig. 1 of Chau does not perform such a
slewing operation. On this point, we are in agreement with
appellants’ basic position. We reach a similar conclusion with
the deskewing operation performed in Fig. 4 of Murray and
discussed beginning at col. 3, line 66.
