corrugated prior to welding (abstract; column 3, line 48 to column 4, line 31). The thermoplastic resin
can be reinforced with fillers of metal, glass, carbon, ceramic, or other plastics (column 4, lines 65-68).
Figure 1 illustrates staggered weld nodes 35, 55 between sheets 20-27.
Although the rejection is phrased as "Kaun in view of Huebner," the examiner's position
appears to be that it would have been obvious to one of ordinary skill in the art to use an induction-coil
welding technique which heats metallic ferrous particles deposited on node lines
by a magnetic field to perform the welding in Huebner's thermoplastic resin honeycomb core fabrication
method as suggested by Huebner (column 6, lines 3-8) and then to modify that welding technique by
using the stenciling step of Kaun to deposit the metallic ferrous particles
on the node lines because screen printing is considered an equivalent metal particle application process
in the art (Substitute Answer page 8). The examiner (i) maintains the thermoplastic resin sheet of
Huebner could be considered a foil corresponding to appellant's disclosure because "polymeric sheets
heavily loaded with organic or volatile components are used to form fired articles having high porosity"
and Ketcham suggests thin materials can be molded in the green state and subsequently sintered to a
dense or porous structure, and (ii) further notes the specification fails to provide an example of a
suitable foil composition or contents (Supplemental Answer paragraph bridging pages 14-15).
We agree with appellant that Huebner does not disclose or suggest green-tape foil substrates
(Brief page 9) as described in the specification, i.e., green-tape foils "consist[ing] of thin foils of alumina
in the raw state or of another like or analogous material, which have a
