33:7-26, 34:18-29. In Example 1, dishwashing compositions A, C, D, and E
contain, among other things, less than 0.1 part by weight of a lipoxidase and
of a lipase, and 10.4 parts by weight sodium perborate. Id. 54; see also 52.
In Example 6, two colored fabric cleaning compositions contain, among
other things, less than 0.1 part by weight of a lipoxidase, of a lipase, and of a
peroxidase, and less than 1.0 part by weight of sodium perborate. Id. 58. In
Examples 8 and 9, two fabric cleaning compositions contain among other
things, less than 0.1 part by weight of a lipoxidase and of a lipase, and 15
parts by weight sodium perborate. Id. 60. In Example 10, fabric cleaning
composition III contains, among other things, less than 0.1 part by weight of
a lipoxidase and of a lipase.
We find Hermant would have disclosed to one of ordinary skill in this
art a transition metal complex catalyst which can activate bleach compounds
including hydrogen peroxide and peroxy acids or molecular oxygen to
remove stains and inhibit dye transfer when used in bleach and detergent
compositions. Hermant, e.g., abstract, 1:4-17, 3:10 to 7:24. The
compositions contain, among other things, peroxy bleach compounds, a
surfactant, and a builder as well as other conventional ingredients such as
enzymes, such as lipases and oxidases, and hydrogenperoxide sources, such
as sodium perborate and sodium percarbonate. Id., e.g., 7:26 to 16:13.
We find Perkins would have disclosed to one of ordinary skill in this
art a transitional metal complex catalyst which can bleach stains, such as
carotenoid stains, in compositions which do not contain a peroxygen bleach
or source of hydrogen peroxide, that is, in the presence of molecular oxygen,
or which contain a peroxygen bleaching system that includes, among other
