useful as an electrical insulation material, we find no
suggestion to employ PETG in the thermoplastic coating of the
electrical insulation material of the type described in
Pedlow. Accordingly, we reverse this § 103 rejection as well.
REJECTION BASED ON WADE ALONE OR IN COMBINATION WITH MATER
We reverse the examiner’s § 103 rejection of claims
1 through 4 as unpatentable over the disclosure of Wade for at
least one reason expressed by appellant at page 10 of the
Brief. We find that Wade describes wrapping woven glass
fibers in tape form with a multi-layer polyester tape
material. See column 2, lines 42-54. To properly fuse the
polyester tape material to the woven glass fibers, however,
the amorphous layer of the polyester facing the glass fibers
is converted to crystalline. See column 3, lines 17-25.
According to appellant (Brief, page 10), the crystalline
layer of the polyester tape bonded to the woven glass fibers
“will not remelt and resolidify . . . ” as required by the
claims on appeal. The examiner has not disputed this

agree with appellant that the examiner has not established a
prima facie case of obviousness within the meaning of 35
