Appeal No. 2006-1020
Application No. 09/899,066
It is reasonable that one of ordinary skill in the art
would have been motivated to improve the function of the
camera of Beis with the zoom lens of Chino for the purpose
of providing enhanced imaging of distant objects. It would
have been especially obvious given that Beis teaches
insertion and removal of optical filters in response to
detected light intensity and that Chino teaches that
insertion and removal of filters from an optical path
results in an out-of-focus condition. A suggestion to
combine references may come from the nature of a problem to
be solved, leading inventors to look to references relating
to possible solutions to that problem. Pro-Mold and Tool
Co. v. Great Lakes Plastics Inc., 75 F.3d 1568, 1573, 37
USPQ2d 1626, 1630 (Fed. Cir. 1996). In this case, one of
ordinary skill in the art would have been motivated to
correct the out-of-focus condition caused by the filter
manipulation of Beis by incorporating a zoom lens and
control method as taught by Chino such that the filter
induced focus error of Beis is compensated for by the
prestored zoom tracking curves taught by Chino.
