density polyethylene having a green interference pigment and a blue colorant dispersed
therein. These sheets can be cut into pieces and mounted between two pieces of glass.
(Column 6, lines 8-31). Armanini discloses the transmission color is determined by
holding the object, e.g. slides, to daylight to observe the colors produced. (Column 3,
lines 57-66). Accordingly, we conclude that the sheets function as a solar screening
material within the scope of the claimed subject matter.
The claimed invention is directed to a composite, suitable for use as a solar
radiation screening material, comprising a green interference pigment and a
transparent polymer. Armanini’s Example 4 describes a composite material within the
scope of claim 12. The material of Example 4 is said to have a purple transmission
color. (Column 6, lines 26-27). Armanini discloses the transmission color of the
formed products are determined by viewing the products visually in daylight. (Column
3, line 57 to column 4, line 1). Thus, the determination of the transmission color of
the Example 4 product would also function to screen solar radiation from the daylight.
Appellants urge Armanini is directed to decorative effects and there is no
motivation to deduce the present invention. Appellants also urge, “the use of
Armanini’s article as covering for greenhouses would have the disadvantage that
incident light which is utilizable for the plant would be absorbed by the absorption
pigment.” (Brief, paragraph bridging pages 4 and 5). Armanini’s Example 4 discloses a
