Appeal 2007-4310
Application 10/950,830
9. Price describes a method of making the claimed composite sheets or
liners in the following words:
a portion of the liquid foamable material is removed, after it is
applied, from what will be the decorative surface 18, for
example with a knife or other blade. . . . The scraping leaves at
least some portions of the fibers on the decorative surface 18
which, at least to the naked eye, are completely free of the
foamed material.
(830 Application at 5, ¶ 24.)
10. As a result, according to Price, "[t]he coating on the non-slip
surface 16 is thus generally thicker, on average, than on the decorative
surface. This results in a larger portion of the foam being on the side of the
scrim adjacent surface 16 after foaming and drying." (830 Application at 5,
¶ 24.)
Mangum
11. Mangum relates to non-slip products such as kitchen drawer inserts
having multiple scrims, each coated with liquid polyvinyl chloride that is
then baked in an oven to form foamed coating layers around the scrims.
(Mangum at 1:7-17.)
12. Mangum describes the coated scrims as being "welded" together when
they are heated together in the oven. (Mangum, e.g., at 2:65 and at 3:62.)
13. Mangum teaches that a variety of scrims may be used (Mangum
at 1:37–61), stating that "the type of scrim utilized often effects [sic: affects]
the porosity, as well as amount of coating retained by the scrim." (Mangum
at 1:61–63.)
