Appeal 2007-2079
Application 10/185,220
1. A decorative laminate material, comprising:
a base layer of fibers selected from a group consisting of polyester,
polypropylene, polyethylene, fiberglass, natural fibers, nylon, rayon and
blends thereof having a density of between about 0.5 pcf and about 15.0
pcf, said base layer having a thickness of between about 0.25 and about 3.0
inches; and
a facing layer of polyester fibers having a density of between about
10 pcf and about 100 pcf, and producing an air flow resistance of between
about 100,000 and about 3,500,000 mks rayls/meter, said facing layer
having an exposed, printed face and a thickness of between about 0.01 and
about 0.1 inches.
The Examiner relies upon the following references:

Appellant’s claimed invention is directed to a decorative laminate
material comprising a base layer having a thickness of between about 0.25
and about 3.0 inches and a facing layer of polyester fibers having a thickness
of between about 0.01 and about 0.1 inches. The face layer produces an air
flow resistance of between about 100,000 and about 3,500,000 mks
rayls/meter. The base layer of fibers has a density of between about 0.5 pcf
(0.008009 g/cm3) and about 15.0 pcf, (0.240276 g/cm3) and the facing layer
of polyester fibers has a density of between about 10 pcf (0.160184 g/cm3)
and about 100 pcf (1.60184 g/cm3).1
1 The Specification does not define “pfc;” however, for purposes of this
appeal, we presume that “pfc” refers to pounds per cubic foot.
