frame for supporting said display, optics and said at least
one transparency, wherein the at least one transparency is
removably mounted on the frame and the optics are removably
mounted on the at least one transparency. We note the
examiner’s position that the mirror or optics (120) of Furness
is mounted on a shaft to allow for pivoting movement and set
in place with a set screw (130) see Col. 9, lines 13-18, and
therefore that the mirror or optics (120) is removably
mounted. Appellants argue that Furness does not teach the
mirror being removable. As we indicated above, in our
treatment of independent claims 29 and 33, after careful
consideration of Furness, we agree with appellants that
Furness does not teach removably mounting the mirror or optics
(120) to the transparency (126). Furness only discloses that
the mirror (120) is mounted on a shaft for pivotal movement
and that the mirror can be secured in an adjustable position.
There is nothing in Furness that teaches or suggests to one of
ordinary skill in the art that the mirror (120) is, or can be,
removably mounted on the frame. Moreover, we note that Landis

also fails to teach the removably mounted optics required by
