Appeal No. 2000-2188 Page 11
Application No. 09/063,050
1576, 1582, 39 USPQ2d 1573, 1576 (Fed. Cir. 1996)). In the
present case, absent any specified external source of clock
signal, “an externally applied clock signal” is a signal that is
merely external to the first means.
With respect to Appellants’ claim 4, we also find that the
claim requires a voltage generator comprising a pump controller
that receives “an externally applied clock signal” and an
“externally applied control signal.” The pump controller then
outputs “first, second and third signals.” As discussed above
with respect to claim 1, we conclude that “an externally applied
clock signal” is a signal that is required to be external with
respect to only the pump controller.
A rejection for anticipation under section 102 requires that
each and every limitation of the claimed invention be disclosed
in a single prior art reference. See Atlas Powder Co. v. Ireco
Inc., 190 F.3d 1342, 1347, 51 USPQ2d 1943, 1947 (Fed. Cir. 1999);
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
