Appeal No. 95-1626
Application 07/804,013
This is a decision on the appeal under 35 U.S.C. § 134
from the examiner's rejection of claims 1-45, which constitute
all the claims in the application. A first amendment after
final rejection was filed on May 24, 1994 but was denied entry
by the examiner. A second amendment after final rejection was
filed contemporaneously with the appeal brief and was entered
as the result of a decision on petition [Paper #24].
The disclosed invention pertains to a magnetoresistive
(MR) element. The MR element of the invention is comprised of
a multilayer film having ferromagnetic and nonferromagnetic
layers layered on each other. A particular feature of the
invention relates to the manner in which a magnetic bias field
is applied to the MR element to give the element desired
properties.
Representative claims 1 and 4 are reproduced as
follows:
1. A magnetoresistive element, comprising a
multilayer film having ferromagnetic layers and
nonferromagnetic layers layered on each other, wherein a
nonferromagnetic layer is formed on the multilayer film, a
permanent magnet layer is formed on the nonferromagnetic
layer, on the multilayer film, and a bias field generated by
said permanent magnet layer is applied to the multilayer film.
