Appeal 2007-1798
Application 10/347,666
INTRODUCTION
The claims are directed to an electrolyte composition. Claim 1 is
illustrative:
1. An electrolyte composition comprising 0.01-5%, by weight,
sodium silicate and 0.01-5%, by weight, α-amino acid wherein said
composition has a pH of at least about 5 to no more than about 7.
The Examiner relies on the following prior art references to show
unpatentability:
Wehrmann US 3,824,159 Jul. 16, 1974
Claims 1-13 and 63 stand rejected under 35 U.S.C. § 103(a) as
unpatentable over Wehrmann.
We affirm.
DISCUSSION
Claim 1-13 and 63 stand rejected under 35 U.S.C. § 103(a) as
unpatentable over Wehrmann. The claims were not separately argued and
therefore stand or fall together. 37 C.F.R. § 41.37(c)(1)(vii). Accordingly,
we limit our discussion to representative claim 1. Claims 2-13 and 63 stand
or fall with claim 1.
Claim 1 is drawn to an electrolyte composition. The composition
comprises:
1) 0.01-5%, by weight, sodium silicate; and
2) 0.01-5%, by weight, α-amino acid.
Claim 1 further requires that the pH of the composition is at least about 5 to
no more than about 7.
