Appeal 2007-1397
Application 10/375,238
e.g., 3:12-25. The ligands and complexes in these reference are
encompassed by the claim terms “organic ligand” and “complex with a
transition metal” in claim 1 and the claim term “transition metal catalyst” in
claim 20.
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.
We find Baeck would have disclosed to one of ordinary skill in this
art detergent compositions which include lipoxidase enzymes that oxidize
carotenoid chromophores and inhibit the transfer of bleachable dyes from
the aqueous wash solution to a substrate. Baeck, e.g., 1:13 to 2:3, 2:6-8 and
12-20, 3:1-27, and 4:28 to 5:19. Baeck defines “lipoxidase enzyme” as “an
enzyme which acts to oxidise polyunsaturated fatty acids to their
corresponding hydroperoxide form,” and include the enzyme “carotenase.”
Id. 4:8-12. The compositions contain at least a lipoxidase enzyme, a
surfactant and/or builder, and other ingredients used in aqueous solutions.
Id., e.g., 3:29-33, 4:2-7, 5:21-29, 46:22-27. The formulations can include
bleaching agents and additional enzymes. Id., e.g., 6:4-10. The bleaching
agents can be, among other things, inorganic perhydrate salts, peroxyacid
bleach precursors and organic peroxyacids, including sodium perborate and
sodium percarbonate. Id., e.g., 28:29 to 32:10. The additional enzymes can
be, among other things, lipases and peroxidases, the latter used with oxygen
sources in solution bleaching to prevent dye transfer. Id., e.g., 32:12-18,
