Appeal No. 2000-0453
Application No. 09/083,901
BACKGROUND
Appellant's invention relates to a DC-to-DC converter providing high current and
low voltage. An understanding of the invention can be derived from a reading of
exemplary claim 1, which is reproduced below.
1. A DC-to-DC converter comprising:
a synchronous rectifier converter, said synchronous rectifier converter
comprising a buck converter;
the transformer of said synchronous rectifier converter employing less than five
windings on the secondary of the transformer.
The prior art references of record relied upon by the examiner in rejecting the
appealed claims are:
Butcher et al. (Butcher) 4,399,499 Aug. 16, 1983
Gegner 5,477,131 Dec. 19, 1995
Claims 1-7 stand rejected under 35 U.S.C. § 103 as being clearly anticipated by
Gegner. Claims 8-18 stand rejected under 35 U.S.C. § 103 as being unpatentable over
Gegner in view of Butcher.
Rather than reiterate the conflicting viewpoints advanced by the examiner and
appellant regarding the above-noted rejections, we make reference to the examiner's
answer (Paper No. 14, mailed Oct. 26, 1999) for the examiner's reasoning in support of
the rejections, and to appellant's brief (Paper No. 13, filed Oct. 12, 1999) for appellant's
arguments thereagainst.
