Appeal No. 95-3977
Application 08/004,075
According to appellants, the invention is directed to an
aqueous antimicrobial composition and its method of use, where
the composition contains a microbiocidal amount of a C -C
1 4
peroxycarboxylic acid and an effective biocidal amount of a C -C
6 18
peroxycarboxylic acid (brief, page 2).
Appellants state that, for each of the stated rejections,
the claims stand or fall together (brief, page 4). The subject
matter on appeal is adequately illustrated by claims 27, 46 and
61, reproduced below:
27. An aqueous peroxyacid antimicrobial composition
consisting essentially of:
(a) at least about 10 parts per million (ppm) of a C -C
1 4
peroxycarboxylic acid; and
(b) at least about 1 ppm of an aliphatic C -C
6 18
peroxycarboxylic acid; wherein the aqueous composition has a pH
in the range of about 2 to 8.
46. A method of sanitizing substantially fixed in-place
process facilities comprising the steps of:
(a) introducing into the process facilities the composition
0 0
of claim 27 at a temperature in the range of about 4 C to 60 C.;
(b) circulating the composition through the process
facilities for a time sufficient to sanitize the process
facilities; and
(c) draining the composition from the process facilities.
