Appeal No. 96-2945
Application No. 08/263,163
ordinary skill in the art, and we note that appellants have
not responded to the examiner's finding that:
[T]he improvement in the water emulsion stability
upon increasing of the amount of the polar
functional groups grafted upon the copolymers does
not appear to be unexpected since it goes to the
well known scientific principle of solubility, and
the fact that a more polar compound will be more
soluble in a polar solvent - water.
(See page 9 of Answer). Furthermore, as noted above, Asahi
discloses a preference for using at least 4% by weight of the
acid compound, and appellants have presented no objective
evidence that the hydrogenation of Asahi's block copolymers
produces unexpected results.
In conclusion, based on the foregoing, the examiner's
decision rejecting the appealed claims is affirmed.
