Appeal No. 1997-0218
Application No. 08/182,757
preparing a separate composition comprising the ultraviolet
radiation absorbing material and polyvinyl chloride, would
reduce production time and decrease costs. See In re
Thompson, 545 F.2d 1290, 1294, 192 USPQ 275, 277 (CCPA 1976)
(economic factors alone would have motivated one of ordinary
skill in the art to use the claimed invention). Therefore,
based on the teachings of Beckmann and Kawakubo and the
knowledge of one having ordinary skill in the art, it would
have been obvious to one having ordinary skill in the art to
provide a laminated glazing unit with a separate layer of an
ultraviolet radiation absorbing material as in the claimed
invention. The rejection of claims 77 and 78 is affirmed.
Conclusion
For the reasons set forth herein, the rejection of claims
42-46, 49, 77 and 78 is affirmed, and the rejection of claim
47 is reversed. The application is further remanded to the
examiner for resolution of the issues identified herein
relating to claims 50, 51 and 66.
