Appeal No. 95-3460
Application No. 08/042,303
Sirinyan et al. (Sirinyan) 4,764,401 Aug. 16, 1988
Claims 1, 2, 4 to 6, 8, 14, 16 and 17 stand rejected under
35 U.S.C. 102(b) as being anticipated by Sirinyan.
Claims 3, 7, 9 to 13, and 15 stand rejected under 35 U.S.C.
§ 103 as being unpatentable over Sirinyan.
In their brief, appellants do not separately argue any of
their claims and thus the claims are considered to stand or fall
together as grouped. Independent claim 1 and dependent claim 3
are sufficiently representative of their groups and read as
follows:
1. A process for depositing metallic material onto a substrate
surface, comprising the steps of:
a.) providing an activator compound homogeneously
distributed in a solvent, the activator compound being
an ionogenic compound capable of releasing platinum
metal ions, the solvent including an organic or
inorganic acid;
b.) adding an anionic surfactant to the solution provided
in step a.), the anionic surfactant being a sulfonic
acid; and
c.) applying the solution provided in step b.) to said
surface, whereby catalytically active platinum metal is
deposited onto said surface.
3. The process according to claim 1, wherein said anionic
surfactant is n-alkylarylsulfonic acid.
After having reviewed the reference in light of the
arguments by the examiner and appellants, we find that we cannot
sustain these rejections.
