Application No. 08/826,283
a surfactant thereto, with a reasonable expectation of
successfully obtaining the purpose or utility described in
Chagnon.
Accordingly, on this record, we are constrained to reverse
the examiner’s rejection of claims 1 through 6, 8, 9, 11, 12,
19 and 20 under 35 U.S.C. § 103 as unpatentable over the combined
disclosures of Chagnon, Verdone, Rosensweig, Borduz, Hajna and
Moskowitz.
OTHER ISSUES
We observe that Verdone teaches stable colloidal metals in a
non-aqueous medium, which are reduced in the same manner as that
disclosed in the appellants’ application in the presence of a
fatty acid having 10 to 22 carbon atoms or a salt thereof.
Compare Verdone, column 1, lines 62 to column 2, line 50 with the
specification, page 3. The colloidal metals exemplified in
Verdone include silver and tin. See columns 3 and 4, Examples
1 through 5. According to column 4, lines 2-3, of Hajna, the
salts of fatty acids taught in Verdone are known surfactants
(surface active agents).
