Appeal No. 1998-0823
Application 08/630,542
combined with the Braymer reference to achieve the invention
recited in claim 24. We agree with the Examiner that the
proposed combination of Heimstadt, Muller, and Braymer teaches
all of the elements of the claimed invention. We fail to
find, however, that any reference suggests modifying a stereo
microscope to use a single camera instead of two, so that two-
dimensional high resolution photographs may be taken. Braymer
teaches (at column 3, lines 45-62) a multiple image telescope
with a prism slidable such that a user may either view the
image received by the telescope directly, or take a photograph
of that image. Braymer is directed to a telescope, rather
than a microscope, and is therefore directed to solving a
different lighting problem than that solved by Heimstadt or
Muller who have more control over the amount of light received
by their apparatus. Further, because the Braymer patent is
directed to an apparatus having a single viewpiece (or camera
port), Braymer does not provide motivation for the person
skilled in the art to modify the two-camera system of
Heimstadt and Muller so that all available light is deflected
