Appeal No. 1998-1792 Page 3
Application No. 08/453,217
11. A method of controlling power supplied from a battery having a
battery voltage to a portable electronic device, the method comprising the
steps of:
regulating the battery voltage using a boost regulator and providing
a regulator output signal;
generating an internal reference signal from the regulator output
signal for use within the portable electronic device;
digitizing the battery voltage using the internal reference signal and
providing a digitized battery voltage signal;
comparing the digitized battery voltage signal to a software
undervoltage threshold; and
selectively powering-off the portable electronic device in response
to the step of comparing.
Claims 11 and 16 stand rejected under 35 U.S.C. § 102(b) as anticipated by U.S.
Patent No. 5,265,271 (“Marko”). Claims 1, 6, 20, and 25 stand rejected under 35
U.S.C. § 103(a) as obvious over Marko.
OPINION
At the outset, we recall that claims that are not argued separately stand or fall
together. In re Kaslow, 707 F.2d 1366, 1376, 217 USPQ 1089, 1096 (Fed. Cir. 1983)
(citing In re Burckel, 592 F.2d 1175, 201 USPQ 67 (CCPA 1979)). Here, the appellants
stipulate, “[a]ll the pending claims stand or fall together.” (Appeal Br. at 2.) Therefore,
claim 16 stands or falls with representative claim 11, and claims 6, 20, and 25 stand or
