Appeal No. 2003-0401
Application 09/490,954
another multi-axial fabric to form a mirror image arrangement of
the plies (answer, pages 6-7).1
Benzinger discloses a low-cost, readily punchable printed
circuit board base laminate formed by cutting into sheets a
prepreg comprised of an epoxy-impregnated woven fiberglass facing
sheet laminated to an epoxy-impregnated nonwoven fiberglass half-
core, inverting one sheet and placing the half-core against the
half-core of another sheet to form a final composite, the facing
sheets and the half-cores having weights selected such that the
final composite has, after lamination under heat and pressure,
the desired base laminate thickness (col. 1, lines 57-61; col. 2,
lines 28-36). The examiner relies upon Benzinger for an
indication that cutting a single fabric and inverting one piece
onto another piece to form a mirror image structure was known
(answer, pages 7-8).2 Regarding the inverting, Benzinger
discloses (col. 2, lines 28-36):
1 Palmer indicates that the fabric sheets are useful for
making skins of aircraft parts (col. 1, lines 21-23).
2 The portion of Benzinger relied upon by the examiner is
the example wherein Benzinger states (column 4, lines 32-34):
“The prepreg was cut into sheets and one of a pair of such sheets
inverted to place core surfaces of the sheets in engagement to
form a prepreg composite having the desired core thickness.”
