materials. Our position is further supported by the disclosure
in the specification at page 6, lines 13 - 23 which lists the
more preferred substrates as including the cellulose based
substrates; particle board, fiberboard and plywood, which are
similar to FormicaŽ in that they are all cellulose derived
materials. Based upon the above considerations, we conclude
that the reference to Formica COLORCORE fails to discloseŽ
coating materials having expansion properties on the order of
300% different from the substrate material.
Furthermore, the primary reference LP3-1991 refers to,
“problems which arise after fabrication and installation due to
differentials in expansion and contraction between the laminate
and substrate.” See page 45. However, there is no requirement
or recognition that the coating material and the substrate have
the requisite expansion properties required by the claimed
subject matter. Accordingly, we conclude that there is no
reason why one of ordinary skill in the art would have been
motivated to select either the coating or the substrate to
obtain materials which have expansion properties differing on
the order of 300%.
