Appeal 2007-1396
Application 10/375,235
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.
There is no dispute the claim term “lipoxygenase” includes enzymes
known in the art as lipoxidases as shown in Promise Mirror as the Examiner
finds. Office Action 5; Promise Mirror 3, second table. This reference also
evinces “lipoxygenase” is also known as “carotene oxidase.” Promise
Mirror 3, second table. A further discussion of this reference is not
necessary to our decision.
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 5. 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. 5-6. 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. 5-6. With respect to the second ground of rejection, the
Examiner finds Perkins discloses compositions containing a transition metal
