Appeal No. 1999-1942
Application 08/770,037
referred to as "Br__") and the reply brief (Paper No. 16)
(pages referred to as "RBr__") for a statement of Appellants'
arguments thereagainst.
OPINION
The claims are grouped to stand or fall together (Br9).
Claim 1 is analyzed as representative.
Foster discloses an oxide-free resin-impregnated mica
paper tape 12 applied over an oxide-free resin-impregnated
turn mica paper tape 11, but, as to claim 1, does not disclose
the claimed: (1) woven fabric on one side of the mica paper;
and (2) oxide particles dispersed in the woven fabric in just
one of the two layers. The APA teaches resin-impregnated mica
paper 17 having a woven fabric 18 on one side, woven fabrics
18a and 18b on both sides, or a woven fabric 18a on one side
and a nonwoven fabric 18b on the other side. The Examiner
concludes that it would have been obvious to make insulation
layer 12 in Foster from a resin-impregnated mica paper with a
woven fabric on one side in view of the APA (EA4). This
conclusion is properly not challenged by Appellants. A number
of layers of the groundwall insulation 15 in APA figure 1
could arbitrarily be designated as a first insulating layer
