film is useful as a magnetic head core material
(specification, page 2). Claim 1 is reproduced below.
A soft magnetic thin film consisting
essentially of a single layer of a Fe B N
ab c
composition, wherein a, b and c each denote
atomic percent, provided that a + b + c = 100,
and B denotes at least one of Co, Ni and Ru, and
wherein the compositional range is given by
0 — b # 5, and
0 — c — 5,
wherein said composition is substantially
uniform along the thickness of the film,
and wherein said magnetic film has a
coercivity not exceeding 2.5 Oe and a
saturation magnetic flux density B of at
25
least 16 kg measured at a magnetic field of
25 Oe.
The prior art references of record relied upon by the
examiner in rejecting the appealed claims are:
Otomo et al. (Otomo) 4,772,976 Sep. 20, 1988
Kobayashi et al. (Kobayashi) 4,935,314 Jun. 19,
1990
Claims 1-6 and 11-19 stand rejected under 35 U.S.C. § 103
as being unpatentable over Kobayashi and optionally Otomo.
OPINION
Upon careful consideration of the opposing arguments
presented by appellants and the examiner, we find that the
