presented in the appellant’s brief. However, this does not end
our inquiry. In agreement with the examiner, we find that the
teachings of Wilk are reasonably pertinent to the problem
addressed by appellant’s claimed invention. To wit, both the
appellant and Wilk are concerned with facilitating the removal of
pieces of material (PTFE) from a larger substrate of that
material. In other words, in our opinion Wilk represents
analogous art in the sense that it evidences that it is known to
facilitate such removal by providing perforations (cut and non-
cut portions) along the outlines defining the pieces in order to
make it easier or more convenient to shear off the pieces from
the substrate at some later time.
