Appeal No. 1999-0608 Page 11
Application No. 08/571,471
bearing holder in the Moriguchi patent publication 05-043884
and as appellant has not challenged the examiner's
characterization of this disclosure as admitted prior art.
Moreover, although Dan'hata does not use the term "sinter,"
the processing of the resin material disclosed in the last
seven lines of the first full paragraph of page 5 of the
translation thereof appears to us to inherently be a sintering
process. Thus, in our opinion, the combined teachings of
appellant's APA and Dan'hata, even without the teachings of
Matsumoto, would have suggested to one of ordinary skill in
the art at the time of the appellant's invention sintering of
the polyimide-containing resin material taught by Dan'hata to
form the sliding material having a porosity of 10 to 20%.
Accordingly, we shall sustain the examiner's 35 U.S.C. §
103 rejection of claim 1, and claims 2 and 3 which stand or
fall therewith according to page 4 of the appellant's brief.
See In re Nielson, 816 F.2d 1567, 1572, 2 USPQ2d 1525, 1528
(Fed. Cir. 1987) and 37 CFR §§ 1.192(c)(7) and
1.192(c)(8)(iv).
