lines 43-46).
Herbert (abstract) evidences the formation of
electroformed and/or electroplated iron with good ferro-
magnetic properties using a titanium-palladium alloy as a
preferred electrode. Herbert teaches that various iron salts
may be used to obtain an iron plated substrate including
ferrous chloride, ferrous ammonium sulfate, ferrous
fluoroborate and ferrous sulfate (column 2, line 66 through
column 3, line 6). Aluminum plated with nickel is one of
several mandrel materials that is disclosed by Herbert as
being suitable for the iron electrodeposition (column 5, line
63 through column 6, line 5).
The examiner correctly recognizes that Klingenmaier does
not disclose the use of a nickel plating step using an
electroless nickel bath prior to electroplating the iron layer
and the use of an iron sulfate bath for depositing the iron as
called for by the appealed claims herein (answer, page 4).
However, according to the examiner (answer, pages 5-7):
[I]t would have been obvious to one of ordinary
skill in the art to substitute the Ni plating of
Lock for the Cu strike coating of Klingenmaier,
because of the advantages of superior interfacing
taught by Lock in his comparison of the two
