Appeal No. 1996-2239 Page 8
Application No. 08/037,485
relies upon Stephen for a disclosure of amino-carboxylate salts
as light stabilizers for coating various substrates. It is the
examiner’s position that the coating compositions comprise
resinous materials. See Answer, page 4. Andersen is relied
upon as teaching amino-carboxylates as coating materials for
preventing corrosion by covering the surface of a metallic
surface with a protective coating. See Answer, pages 5 and 6.
Accordingly, “the ordinary practitioner would have found it
obvious to formulate a metal article having a coating thereon
which comprises an amino-carboxylate salt, a pigment a binder
and a solvent.” See Answer, page 7. As to this set of claims
we disagree with the examiner’s analysis and conclusions.
The organic materials required by the claimed subject
matter are polymeric materials. Stephen teaches polymeric
materials at column 2, line 62- column 3, line 24. When the
amino-carboxylates are added to a polymeric substrate, they may
be blended before or after polymerization or sprayed on the
surface of polymeric films, fabrics, or filaments. See column
3, lines 50 - 64. However, there is no disclosure, suggestion
or teaching of utilizing the amino-carboxylates together with
the polymeric materials of Stephen as a coating composition.
