switch Q4. The appellants admit, “C13 and C21 have ... one
node in common, ground.” (Reply Br. at 4.) Moreover, the
Figure shows that capacitor C21 is in series with switch Q4
and that capacitor C13 and the combination of capacitor C21
and switch Q4 are both connected a node shown above resistor
R20.
Cumulatively, the Figure also depicts capacitor C14,
capacitor C22, and switch Q5. The appellants admit, “C14 and
C22 have ... one node in common, ground.” (Id.) In addition,
the Figure shows that capacitor C22 is in series with switch
Q5 and that capacitor C13 and the combination of capacitor C22
and switch Q5 are both connected a node shown above resistor
R21.
Because Hebert’s capacitor C13 and C14 are connected
between the same pair of nodes as its capacitor C21 and C22,
respectively, in series with switch Q4 and Q5, respectively,
we are persuaded that the reference discloses the limitations
of "a first capacitor which is in parallel with a second
