Appeal 2007-3412
Application 10/832,450
7. According to the Specification, "[i]n various embodiments of polymer
sheets of the present invention, the polymer sheets can comprise 10 to 90,
15 to 85, 20 to 60, 25 to 60, 20 to 80, 25 to 70, and 25 to 60 parts plasticizer
per one hundred parts of resins." (Specification at 6:13–15.)
8. The Specification indicates that any suitable method can be used to
produce the polymer sheets of the invention and that details of the methods
are well known to those skilled in the art. (Specification at 11:10–12.)
9. Moreover, the Specification indicates that any suitable plasticizer can
be used. (Specification at 12:3-4.)
10. According to the Specification, long term stability can be measured by
subjecting a laminated glass sample to a source of intense UV radiation from
any of several commercially available units and then administering the
Pummel Adhesion Test. (Specification at 8:18–26.)
11. The Specification teaches that in the Pummel Adhesion Test, "[t]he
laminates are cooled to about -17°C (0°F) and manually pummeled with a
hammer to break the glass." (Specification at 13:22–26.)
12. The glass that remains adhered to the PVB sheet is visually compared
with a set of standards and a pummel adhesion ("PA") value is assigned.
When no glass remains adhered, the PA value is zero; when all the glass
remains, the PA value is 10. (Specification at 13:27 to 14:1.)
13. According to the Specification, laminated glass panels of the present
invention have a PA of "at least three, at least 5, at least 8, at least 9, or 10."
(Specification at 14:1–3.)
