things, hydrogen peroxide and sources therefor, among other things,
hydrogen peroxide, percarbonates and perborates. Perkins, e.g.,
1:5 to 9:18, and 37:15-25. The bleaching and detergent compositions can
include additional materials, such as surfactants and builders, as well as an
enzyme such as lipase, which can remove, among other things, triglyceride-
based stains from textiles, and peroxidases. Id., e.g., 9:20 to 10:13, 24:22 to
25:10, and 26:25 to 27:2. In Example 3, a bleaching system composition
contains less than 1 part by weight of the lipase Lipolase and less than 1 part
by weight of catalyst. Id. 38-39 and Table I.
With respect to the first ground of rejection, the Examiner finds Baeck
discloses compositions differing from the claimed compositions in the
absence of a transition metal catalyst, wherein the lipoxidase ingredient of
the compositions removes bleachable stains, including carotenoid soils, and
the compositions can further include lipases and perhydrate salts. Office
Action 4. The Examiner finds Hermant discloses a transition metal catalyst
which activates hydrogen peroxide, peroxy aids and molecular oxygen, and
removes stains and inhibits dye transfer. Id. 5. The Examiner concludes one
of ordinary skill in this art would have used Hermant’s transition metal
catalyst in Baeck’s compositions with a reasonable expectation of success
because Hermant’s catalyst can activate bleach ingredients in Baeck’s
compositions as well as molecular oxygen and provide stain removal and
dye transfer inhibition properties, wherein the proportions of the ingredients
are as claimed. Id.. With respect to the second ground of rejection, the
Examiner finds Perkins discloses compositions containing a transition metal
catalyst that can bleach stains in a bleaching system that has a low amount of
peroxygen bleach, which differs from the claimed compositions in the
