these parameters. Claim 14 recites that a difference in
voltage between the two MR elements is caused by currents
flowing therein. It does not matter for definiteness how
these currents are generated. All that matters is that
currents flowing in the MR elements produce different voltages
measurable by the MR elements. The scope of these claims is
not made indefinite by not reciting the source of the currents
flowing in the MR elements.
F) The examiner argues that it is not clear how a
permanent magnet or nonferromagnetic layer is formed through
the nonferromagnetic layer as in claim 3, for example. Claim
3 does not recite that a permanent magnet is formed through a
nonferromagnetic layer. Claim 3 recites that a
nonferromagnetic metal layer is formed through a
nonferromagnetic insulating layer in a manner that causes a
current flowing in the metal layer to induce a bias field
which is applied to the multilayer film. The specification
makes it clear how these two nonferromagnetic layers are made
to effect the desired result. Therefore, we see no merit in
the examiner’s position on this point.
