Appeal No. 95-3336
Application No. 07/984,448
(brief, page 2). This method includes the steps of joining
ceramic compacts along their mating surfaces by cold isostatic
pressing (CIP) followed by firing the integrated compact to
obtain sintering (id.). Claim 1 is illustrative of the
subject matter on appeal and is reproduced below:
1. A method for manufacturing a ceramic having at least one
hole comprising the steps of:
forming independently at least two ceramic compacts, said
ceramic compacts having their shapes corresponding to the
divided parts of one integrated body having at least one hole
along which the integrated body is divided;
joining said ceramic compacts into an integrated form
having at least one hole by cold isostatic pressing; and
firing the integrated compact.
The examiner has relied upon the following references as
evidence of obviousness:
Hattori et al. (Hattori) 4,248,813 Feb. 3, 1981
Conder et al. (Conder) 4,662,958 May 5, 1987
Yogo et al. (Yogo) 5,106,550 Apr. 21, 1992
Claims 1 through 4 stand rejected under 35 U.S.C. § 103
as unpatentable over Conder in view of Hattori or Yogo
(answer, page 3). We reverse the examiner’s rejection for
reasons which follow.
