Appeal No. 96-1457
Application No. 08/098,165
(column 1, lines 55 through 57). Cummins does not disclose a
specific type of flash. Van Allen discloses an electronic flash
20 (Figure 1) that uses a mirror reflector 34 and Fresnel lens 42
(Figure 7) as a light concentrator in a Polaroid camera. Taylor
discloses that “[c]oncave reflective mirrors are sometimes used
in a variety of imaging systems” (column 1, lines 21 and 22),
that concave mirrors are used by the Polaroid Corporation (column
3, lines 31 through 36), and that Fresnel reflectors are used “as
substitutes for optical surfaces which are described as conic
sections” (column 4, lines 13 through 15). We agree with
appellants’ argument (Reply Brief, page 4) that Taylor does not
specifically mention the use of a Fresnel reflector in a camera.
On the other hand, based upon the noted teachings of Van Allen
and Taylor, we agree with the examiner (Answer, page 10) that “it
would have been obvious to one having ordinary skill in the art
to provide the camera of Cummins with a strobe of Van Allen in
which the light reflector is replaced with a Fresnel reflector as
taught by Taylor, II since it has been known to select a known
reflector on the basis of its suitability for its intended use.”
The obviousness rejection of claims 21 through 23 is sustained.
