Appeal No. 1996-3121
Application No. 08/115,783
Strong et al. (Strong) , “Further Studies on Diamond Growth1
Rates and Physical Properties of Laboratory-Made Diamond”, The
Journal of Physical Chemistry, Vol. 75, No. 12, 1971, pps.
1841-43.
Appealed claims 14 and 15 stand rejected under 35 U.S.C.
§ 112, first paragraph, “enablement requirement”. Appealed
claims 1, 3-7, 9 and 13-15 stand rejected under 35 U.S.C. §
103 as unpatentable over Yamazaki combined with Seitz.
Appealed claims 1, 3-9 and 13-15 stand rejected under 35
U.S.C. § 103 as unpatentable over Yamazaki and Seitz further
in view of Sakamoto.
The subject matter on appeal is directed to a synthetic
diamond coated on a substrate (appealed claims 13 and 15) and
a method for producing diamond by a chemical vapor
deposition(CVD) technique (appealed claims 1, 3-9, and 14)2
which involves the decomposition and reaction of a reaction
1The Seitz patent refers to the Strong publication with
respect to its disclosure of the absorption spectrum of
synthetic diamond having dispersed nitrogen impurities. See
Seitz at column 3, lines 60-68.
2Appellants exemplify and utilize various prior art CVD
techniques including microwave plasma CVD and hot filament
CVD. See the specification at page 3, lines 1-4.
