THE REJECTIONS
Claims 8-13 stand rejected under 35 U.S.C. § 103 over
Takatomi and over Wilson in view of Takatomi.
Appellant states that the claims stand or fall separately
(brief, page 3). However, appellant provides a substantive
argument as to the separate patentability of only the sole
independent claim (claim 8) and dependent claims 11 and 13.
Dependent claims 9, 10 and 12, therefore, stand or fall with
claim 8, and we limit our discussion to claims 8, 11 and 13.
See In re Ochiai, 71 F.3d 1565, 1566 n.2, 37 USPQ2d 1127, 1129
