Appeal No. 1997-0218
Application No. 08/182,757
adhesion between one or both of the inboard and outboard glass
sheets and the polyvinyl chloride film in order to achieve
desired properties such as increased safety and impact
resistance. See In re Boesch, 617 F.2d 272, 276, 205 USPQ
215, 219 (CCPA 1980) (discovery of an optimum value of a
result effective variable in a known process is ordinarily
within the skill of the art). Second, adjusting the level of
adhesion by either varying the thickness of the adhesive
coating or selective placement of the adhesive is well within
the skill of the ordinary artisan, as anyone who has glued two
pieces of paper together would know. See In re Bozek, 416
F.2d 1385, 1390, 163 USPQ 545, 549 (CCPA 1969) (a conclusion
of obviousness may be made from common knowledge and common
sense of the person of ordinary skill in the art without any
specific hint or suggestion in a particular reference); In re
Jacoby, 309 F.2d 513, 516, 135 USPQ 317, 319 (CCPA 1962) (one
of ordinary skill in the art must be presumed to know
something about the art apart from what the references
expressly disclose).
Therefore, for the reasons set forth above, the rejection
of claims 44-46 and 49 is affirmed.
