Grounds of Rejection
Claims 5-22 stand rejected under 35 U.S.C. § 103(a) as obvious over Solomons
in view of Eliasson and Horn.
We affirm the rejection as it applies to claims 5-16 and reverse the rejection as it
applies to claims 17-22.
Claim Grouping
The separate patentability of each of the independent claims is argued separate
and apart from each other. Brief, page 7. Dependent claims are not separately argued
in the Brief. Therefore, we treat claim 5 as representative of claims 5-10, claim 11 as
representative of claims 11-16, and claim 17 as representative of claims 17-22.
