Appeal No. 2004-0149
Application No. 09/803,612
in a wash liquor, with a bleaching composition that contains a
specified transition metal complex bleach catalyst (Brief, page 3).
The bleaching of stains is accomplished with the catalyst in the
presence of atmospheric oxygen without use of aldehydes, and is
substantially devoid of peroxygen bleach or a peroxy-based or
-generating bleach system (id.).
Appellants state that all claims stand or fall together
(Brief, page 5). Therefore, according to the provisions of 37 CFR
§ 1.192(c)(7)(2000), we select independent claim 1 from each
grouping of claims and decide every ground of rejection in this
appeal on the basis of this claim alone. Illustrative claim 1 is
reproduced below:
1. A method of reducing dye fading of fabrics in laundering
of fabrics bearing fadeable dyes in the presence of bleaching
compositions, comprising contacting stained fabrics bearing
fadeable dyes, in a wash liquor, with a bleaching composition that
comprises a bleach catalyst,
wherein the bleach catalyst comprises an organic ligand which
forms a complex with a transition metal, the complex catalysing
bleaching of stains by atmospheric oxygen without use of aldehydes,
and the composition allows at least 50% of any bleaching of the
fabric to be effected by oxygen sourced from the air and is
substantially devoid of peroxygen bleach or a peroxy-based or
-generating bleach system.
