Appeal No. 96-4043
Application 08/235,538
light-trapping members “consist of sheets with fluffs as facing
layers and flexible or compressible materials as base layers”
(column 3, lines 53 through 55). Mizuno teaches that “a material
for the sheets can be selected from among woven and knitted
fabrics of synthetic fiber such as nylon, polyester and acrylic,
regenerated fiber such as rayon, cupro and natural fiber such as
cotton, silk and sheep wool; non-woven fabrics; synthetic
leathers; fluffy materials; flocked material and films” (column
3, lines 56 through 62). In Example 5,
[a] polyester thread of 70 denier/20 filaments was
used to form a ribbon of a twill fabric in accordance
with a weave illustrated in FIG. 6 in which one warp
thread overlies two weft threads and underlies one weft
thread alternately. . . . The ribbon was then treated
for raising by a cylindrical sand grinder to form short
loops 0.2 mm long, as fluffs, and cut at a
predetermined size to obtain the sheets [column 8,
lines 6 through 22].
It is not disputed that the Mizuno cassette meets all of the
limitations in appealed claim 12 except for those relating to the
specifically defined light-locking material.
Okamoto discloses “a raised woven fabric whose surface is
covered with extra-fine fibers having a suede-like touch,
appearance and feel” (column 1, lines 5 through 7). Figure 2
illustrates a cross-sectional schematic view of a raised woven
fabric
