B) an aliphatic carboxylic acid of 8 to 24 carbon atoms or a
mixture of said carboxylic acids
C) a cationic surfactant or a mixture of said surfactants,
said components A to C accounting for 10 to 40% by weight of said
dispersion and said dispersion including said components A, B and
C in the following amount ratios relative to each other:
A): 10 to 20 parts by weight
B): 25 to 80 parts by weight
C): 25 to 150 parts by weight.
The examiner relies upon the following reference as evidence
of obviousness:
Trinh et al. (Trinh) 5,932,253 Aug. 3, 1999
Appellants' claimed invention is directed to a composition
comprising an aqueous dispersion of (A) an unsubstituted
cyclodextrin, (B) an aliphatic carboxylic acid having 8 to 24
carbon atoms, and (C) a cationic surfactant. While it was known
in the art to treat textiles with cyclodextrins, "[i]t is an
object of the present invention to provide aqueous dispersions
for the treatment of fiber materials, especially non-made-up
textile fabrics, which retain the advantages of cyclodextrin
formulations while producing a very soft hand" (page 1 of
specification, paragraph five). According to appellants, "[i]t
is also surprising that the pronounced hydrophilic properties
imparted to the fiber materials by cyclodextrins in [a] known
