Appeal No. 1997-0258
Application No. 08/251,052
303, 313 (Fed. Cir. 1983), cert. denied, 469 U.S. 851 (1984).
With respect to independent claims 1 and 7, the Examiner
attempts to read the various limitations on the Hsieh
reference (Answer, pages 5-7). Appellants’ arguments in
response (Reply Brief, page 2) center on the alleged
deficiency of Hsieh in disclosing the claimed establishment by
the reset circuitry of a DC current path to ground after a
first power up detection signal and only after a reference
voltage has terminated to enable production of a second power-
up detection signal, a feature which appears in all of the
independent claims on appeal.
After careful review of the Hsieh reference in light of
the arguments of record, we are in agreement with Appellants’
stated position in the Briefs. The Examiner, apparently
recognizing the lack of any explicit description of a DC
current path to ground in the reset circuitry of Hsieh,
nonetheless offers the conclusion that, by necessity, Hsieh’s
AND gate 83 must have pull-down circuitry to pull output node
4E’ low by a current path to ground. No support on the
record, however, has been presented by the Examiner for this
