comprising mixing an organopolysiloxane containing certain
specified higher alkenyl groups with an organohydrogensilicon
compound, a platinum group metal-containing catalyst, a silylated
acetylenic compound, and optionally a diluent (Brief, page 2).
Appellants state that “[n]o grouping of the claims is
necessary for the purposes of this appeal.” Brief, page 3. We
construe this statement as meaning that the claims stand or fall
together (see the Answer, page 2, ¶7). Accordingly, we select
independent claim 35 from the grouping of claims for each
rejection and decide this appeal as to these grounds of rejection
on the basis of this claim alone. See 37 CFR
§ 1.192(c)(7)(1997). A copy of this claim is attached as an
Appendix to this decision.
