Appeal No. 2002-1173
Application No. 09/510,640
In re Paulsen, 30 F.3d 1475, 1478-79, 31 USPQ2d 1671, 1673 (Fed.
Cir. 1994). Anticipation is established only when a single prior
art reference discloses, expressly or under the principles of
inherency, each and every element of a claimed invention as well
as disclosing structure which is capable of performing the
recited functional limitations. RCA Corp. v. Applied Digital
Data Sys. Inc., 730 F.2d 1440, 1444, 221 USPQ 385, 388 (Fed. Cir.
1984).
Upon a review of Hsieh, we agree with Appellants that the
reference fails to teach replicating the operations performed
prior to the reset signal. The power supply voltage sensing
circuit of Hsieh generates a reset signal not only when the power
supply voltage is first applied to the circuit, but also when the
power supply voltage level falls below a selected value (col. 1,
lines 11-14). The reset signal holds the integrated circuit in a
known state until the power supply voltage returns to its
selected value where the integrated circuit may function reliably
(col. 4, lines 3-9). This arrangement differs from the claimed
“repeating operations of the integrated circuit which ... have
(possibly) been influenced by the dip in the supply voltage”
since the reset signal of Hsieh, similar to its power-on reset,
clears all the data to the initial state and waits for the next
