Interference No. 104,158
To summarize our findings with respect to the
location of axis XX in Kirk, the first embodiment teaches that
axis XX
intersect axis YY or be adjacent thereto. If it intersects
YY, it is not at or below the surface to be shaved. With
respect to the “adjacent to” language, the reference is silent
as to in which direction the axis is displaced from axis YY
and by what amount. To expand this to a teaching of an axis
at or below the surface to be shaved is to base a necessary
factual finding on speculation or conjecture. The two other
embodiments of Kirk clearly disclose axis XX as well above the
surface to be shaved. Thus, it is our finding that Kirk never
teaches nor suggests a pivot axis XX at or below the surface
to be shaved.
The differences between the Kirk reference and
Oldroyd’s claimed subject matter are two. As explained above,
Kirk does not teach a pivot axis XX below the surface to be
shaved. Kirk also does not teach a four-bar linkage to carry
the cartridge carrier.
The Terry reference discloses a wet shaver with a
handle 10 which supports a shaving unit 20 containing the
