resin from step (b) with 0.4 to 5 grams, per kilogram
of hydrogen-form weak acid cation exchange resin, of
an antimicrobial agent selected from one or more of
peroxides, (C2-C3)alcohols and inorganic chloride
salts.
The examiner relies on the following prior art references
as evidence of unpatentability:
Nagai et al. 4,245,053 Jan. 13, 1981
(Nagai)
Ballard et al. 5,900,146 May 04, 1999
(Ballard)
Kubota et al. 5,954,965 Sep. 21, 1999
(Kubota)
Claims 1 through 6, 9, and 10 on appeal stand rejected
under 35 U.S.C. § 103(a) as unpatentable over Ballard and Nagai.
(Examiner’s answer mailed Sep. 4, 2002, paper 14, pages 5-7.)
Correspondingly, claims 7 and 8 on appeal stand rejected under
35 U.S.C. § 103(a) as unpatentable over Ballard, Nagai, and
Kubota. (Id. at page 7.)
We affirm these rejections.2
2 The appellants submit that “[c]laims 1-10 stand or fall
together.” (Appeal brief, p. 3.) We interpret this statement
to mean that the claims in each of the two grounds of rejection
stand or fall together; that is, claims 1-6, 9, and 10 stand or
fall together and claims 7 and 8 stand or fall together.
