Appeal No. 1999-1855
Application 08/738,916
Claims 21 and 23
In claim 21: (1) there is no antecedent basis for the
first occurrence of "said supply voltage"; and (2) it is
unclear where the "output voltage" is produced.
Appellant argues that claim 21 recites "a voltage
enhancement circuit connected to said supply voltage that
generates an enhanced voltage that is greater than said supply
voltage," "a capacitor having a first node connected to said
enhanced voltage and a second node connected to said supply
voltage during a first phase," and "switches that disconnect
said first and second nodes of said capacitor from said supply
voltage and connect said first node to a reference voltage,
that is less than said supply voltage, during a second phase
to produce an output voltage that is less than said reference
voltage during said second phase," none of which are remotely
taught or suggested in figure 3 or the disclosure associated
with figure 3 (Br9; RBr3). It is argued that figure 3 does
not teach using an enhanced voltage or connecting a capacitor
between an enhanced voltage and a supply voltage (Br10).
We agree that these limitations of claim 21 are not
disclosed in figure 3 or the accompanying discussion. The
