Appeal No. 95-2327
Application 08/119,448
Claim 24 is illustrative of the appealed claims and reads as
follows:
24. A method of producing a diamond article comprising:
depositing a diamond layer by chemical vapor deposition
on a surface of a thermally stable substrate consisting of a tube
open at both ends and having an inner surface and an outer
surface, said outer surface having a shape substantially the same
as that of the desired interior of said diamond article, while
supporting said substrate to prevent distortion thereof; and
submerging said substrate and diamond layer in a vertical
position in an etching bath and ultrasonically agitating said
etching bath to remove said substrate by etching of the inner
surface thereof.
The references relied on by the examiner are:
Jansen et al. (Jansen) 4,925,701 May 15, 1990
Ohata (Japanese Kokai) 1-138110 May 31, 1989
Since appellants' brief does not contain a statement that
the claims do not stand or fall together, the claims do stand or
fall together. 37 CFR § 1.192(c)(7). Accordingly, we will limit
our consideration to claim 24.
Claims 24-27 and 30 stand rejected under 35 USC § 103 as
unpatentable over Ohata alone or when taken in view of Jansen.
Claims 24-27 and 30 stand further rejected under 35 USC § 103 as
unpatentable over Jansen. We reverse.
