Appeal No. 1997-1807
Application No. 08/395,248
BACKGROUND
At the outset, we note that Patent and Trademark Office
(PTO) records indicate that the present application was filed
on February 27, 1995, as a divisional of U.S. Application No.
08/167,385, which parent application was filed on December 15,
1993. Also, copending and related Application No. 08/394,935
was filed on February 27, 1995, as a continuation of the
above-noted parent application. The above-noted related and
copending Application No. 08/394,935 is also before us on
appeal (Appeal No. 1997-1748).
Appellant's invention relates to a method of applying a
coating to a chalky substrate with an alleged improved
adhesion via the blending of a macromolecular aqueous
dispersion with an acid-functional alkali-soluble polymer and
an aminosilane compound. The aminosilane reduces the acid
functionality of the acid-functional alkali-soluble polymer.
The product paint/coating of the claimed method is also
claimed. An understanding of the invention can be derived
from a reading of exemplary claim 10, which is reproduced
examiner (answer, page 4) and hence those proffered amended
claims are not before us for review in this appeal.
