Appeal No. 95-5066
Serial No. 07/931,330
ACS Hospital Systems, Inc. v. Montefiore Hospital, 732 F.2d 1572, 1577, 221 USPQ 929, 933
(Fed. Cir. 1984). These showings by the examiner are an essential part of
complying with the burden of presenting a prima facie case of obviousness. In re Oeticker, 977 F.2d
1443, 1445, 24 USPQ2d 1443, 1444 (Fed. Cir. 1992).
With this as background, we turn to the rejections of the appealed claims.
1. Rejection of claims 1-2 as unpatentable over Hamuro, Ketcham and Dubuisson
Harumo laminates ceramic green sheets which are to become electrical elements by heat
welding the sheets (i.e., foils) together as they are individually stacked using coincident
successive welding at the same location on each sheet using hot iron 11 (see Figure 3; column 2, lines
16-29, 50-53 and 55-59; column 3, lines 13-18, 41-46 and 53-65).
Ketcham makes sintered structures with multidimensional flexibility by mixing green materials,
such as aluminas, with sufficient solvent to obtain fluid vicosity, forming the mixture into thin sheets or
other preforms using conventional thin sheet or foil forming means, such as doctor blading, rolling,
printing, molding, extrusion, casting, etc., and sintering the thin sheets or preforms (column 3, lines 34-
46; column 4, lines 20-31 and 54-63; column 8, lines 36-44;
column 9, lines 46-48).
