(see column 2, lines 22-49).
We find that those skilled in the art, having the
teachings of Heimstadt, Muller, and Jakubowski before them,
would have included a beam divider between the objective lens
and the optical relay lenses, such beam divider operative to
direct a portion of the light beam from the objective lens to
a camera port because Jakubowski teaches the desirability of a
camera at such a position, so that the camera may be
controlled without interfering with the surgeons' conduct of
an operation (see column 1, line 63 to column 2, line 11).
Therefore, we find that it would have been obvious to modify
