Appeal No. 2003-1525
Application 09/462,876
THE REJECTIONS
The claims stand rejected as follows: claims 1 and 4-8 under
35 U.S.C. § 102(b) as anticipated by or, in the alternative,
under 35 U.S.C. § 103 as obvious over Suzuki or JP ‘068, and
claims 9 and 10 under 35 U.S.C. § 103 as obvious over Kawasaki in
view of Suzuki.
OPINION
We reverse the rejections of claims 1 and 4-8 and affirm the
rejection of claims 9 and 10.
Rejections of claims 1 and 4-8
We need to address only claim 1, which is the sole
independent claim among claims 1 and 4-8.
The examiner argues that Suzuki discloses a cubic boron
nitride (cBN) sintered body (col. 1, lines 9-10) which is formed
by a direct conversion method (col. 2, line 44) at a temperature
of 1900-2100ēC and a pressure of at least 6.5 GPa (col. 4,
lines 64-67) for preferably at most 120 minutes (col. 5, lines 1-
2), has an average primary crystal grain size of preferably at
most 1.0 :m (col. 4, lines 4-7), and is useful for cutting cast
iron (col. 5, lines 22-24) (answer, page 4).
