hand, argues that "the components in figure 2 are not, in
reality, suspended in space; each component is secured in the
system. The mirror may not be directly attached to the lens,
but it is secured to the lens, albeit through intermediate
components." (Answer at 4.)
In our view, this interpretation of "secured to said lens" is
a reasonable one. As explained in In re Hyatt, 54 USPQ2d
