Appeal No. 1996-3535
Application No. 08/236,006
The subject matter on appeal relates to a process for
electrolessly metallizing a body to provide on the surface
thereof a metal coating incorporating therein particulate
matter which comprises contacting the surface of the body with
an electroless metallizing bath which contains a particulate
matter stabilizer that shifts the Zeta potential for the
particulate matter by at least 10 mv. Further details of this
appealed subject matter are set forth in representative
independent claim 20 which reads as follows:
20. A process for electrolessly metallizing a body to
provide on the surface thereof a metal coating incorporating
therein particulate matter which comprises contacting the
surface of said body with an electroless metallizing bath
comprising an aqueous solution of a metal salt, a reducing
agent, a quantity of insoluble particulate matter and a
quantity of particulate matter stabilizer, wherein said
particulate matter stabilizer shifts the Zeta potential for
said insoluble particulate matter by at least 10 mv in
comparison to the measured Zeta potential of said insoluble
particulate matter alone in water.
The references set forth below are relied upon by the
examiner as evidence of obviousness:

All of the appealed claims are rejected under the first
paragraph of 35 U.S.C. § 112 as being based upon a disclosure
