Appeal No. 95-0800
Application 07/840,276
Claim 1 reads as follows:
1. A thin film magnetic head which comprises 2n (n
being an integer of not less than 1) spiral patterns formed by a
selective plating method, n spiral patterns out of the 2n spiral
patterns being connected in series so that a first connecting
terminal and an intermediate connecting terminal are formed to
thus give a first coil, the remaining n spiral patterns out of
the 2n spiral patterns being connected in series so that one end
thereof is connected to the intermediate connecting terminal and
the other end serves as a second connecting terminal to thus give
a second coil, wherein the 2n spiral patterns are formed on n
layers and each layer has two spiral patterns formed on the same
layer, one of which is a component of the first coil and the
other of which is a component of the second coil.
The Examiner’s Answer cites the following prior art:
Romankiw et al. (Romankiw) 4,295,173 Oct. 13, 1981
Takahashi 4,416,056 Nov. 22, 1983
Jones, Jr. et al. (Jones) 4,713,711 Dec. 15, 1987
OPINION
The claims stand rejected under 35 U.S.C. § 102 as
anticipated by Takahashi and under 35 U.S.C. § 103 as
unpatentable over Jones in view of Romankiw.
Anticipation by Takahashi
Appellants argue that Takahashi does not have “two
spiral patterns formed on the same layer” as recited in the
claims. The examiner argues that one “layer” may be broadly
interpreted to include multiple layers that are partially in the
same plane. We agree with appellants.
