Appeal No. 1999-2518
Application 08/722,213
Rejection of claims 8, 13 and 24 under 35 U.S.C. § 103
over Collier in view of Panandiker and Willey
The appellants state that claims 8, 13 and 24 stand or fall
together (brief, page 4). We therefore limit our discussion to
one claim in this group, i.e., claim 8, which depends from
claim 5 and recites that the peroxyacid bleach precursor is
selected from a recited group of compounds.
Willey discloses acyl verolactams which fall within the
scope of the N-acylated lactam bleach precursors recited in the
appellants’ claim 8, and teaches that they have the advantages of
1) forming peroxyacids upon perhydrolysis without the production
of oily, harmful diacylperoxides, thereby providing good cleaning
performance without damaging natural rubber parts and articles,
and 2) being effective at low concentrations and at temperatures
below 60ēC (col. 1, line 59 - col. 2, line 8; col. 2, lines 22-
38). This teaching would have fairly suggested, to one of
ordinary skill in the art, use of Willey’s bleaching system in
Collier’s detergent to obtain these benefits.
The appellants argue that Willey does not suggest the
delayed release characteristic of the peroxyacid bleach source as
required by claim 5 (brief, page 14). This release
characteristic, however, would have been fairly suggested to one
