Interference No. 104,158
skill has been described as a mechanical engineering degree
and several years of experience in the wet shaving razor art. 6
With the above-noted factual findings in mind, it is
our determination that the subject matter of Oldroyd claim 9
would not have been obvious to one of ordinary skill in view
of the combined teachings of these references. We do not
reach the
issue of motivation to combine vis-a-vis impermissible
hindsight in view of our finding, in agreement with factual
finding 37 of Oldroyd, that the references taken singly or
together do not teach the claim limitation that the pivot axis
lies on or beneath the surface being shaved. Only Kirk
teaches a pivot axis perpendicular to the edge of the blades,
and Kirk teaches that this
axis XX should be adjacent to the pivot axis YY in one
embodiment
