Appeal No. 94-3134
Application 07/848,884
The subject matter on appeal relates to a composition
comprising (1) hexamethylenetetramine, (2) aminobenzoic acid
or phenol, (3) a water soluble acrylamide-containing polymer,
and (4) water. This appealed subject matter is adequately
illustrated by independent claim 1 which reads as follows:
1. A composition comprising (1) hexamethylene-
tetramine; (2) a crosslinking component selected from the
group consisting of a water dispersible aminobenzoic acid
compound and phenol; (3) a water soluble acrylamide-containing
polymer; and (4) water.
The references relied upon by the examiner as evidence of
obviousness are:
Mumallah et al. (Mumallah) 4,799,548 Jan. 24, 1989
Moradi-Araghi et al. 5,043,364 Aug. 27, 1991
(Moradi-Araghi) (filed Mar. 15, 1990)
All of the claims on appeal stand rejected under 35 USC
§ 103 as being unpatentable over Moradi-Araghi in view of
Mumallah.
