Appeal No. 2001-1627
Application No. 09/289,420 Page 2
BACKGROUND
Appellant's invention relates to a DC-DC voltage converter.
An understanding of the invention can be derived from a reading
of exemplary claim 1, which is reproduced as follows:
1. A DC-to-DC converter having an input voltage and an
output voltage, comprising:
a circuit topology such that, in operation, the input and
output voltages have the same polarity, and that a magnitude of a
ratio of the input voltage to the output voltage of said DC-to-DC
converter is capable of being equal to, greater than, or less
than one;
said circuit topology being further such that at least one
capacitor and alternative coils of a two-coil inductor are
employed in a primary and a secondary circuit loop of said
DC-to-DC converter;
said primary and secondary circuit loops not being
electrically isolated.
The prior art references of record relied upon by the
examiner in rejecting the appealed claims are:
Cuk et al. (Cuk) 4,274,133 June 16, 1981
Bang 5,621,625 Apr. 15, 1997
Yasumura 5,835,368 Nov. 10, 1998
Claims 1-31 stand rejected under 35 U.S.C. § 102(e) as being
clearly anticipated by Yasumura.
Claims 1-25 stand rejected under 35 U.S.C. § 102(b) as being
clearly anticipated by Cuk.
