Appeal No. 96-1530
Application No. 07/767,488
Claims 8 through 14, 16 and 17 stand rejected under 35
U.S.C. § 103 as unpatentable over the combined teachings of
Jin and Takekawa. We reverse.
In prior art processes, plate-shape superconducting oxide
particles are produced by heat treating superconducting oxide
powder to, for example, about 900 C to 1050 C for a prolongedo o
period. See specification, page 5, lines 16-28, page 8, lines
21 to page 9, line 3 and pages 12-29, examples 1 through 8 in
conjunction with Takekawa, L852. The superconducting-plate-
shaped particles resulting from this heat treatment, however,
“do not have any particular preferred orientation and are
oriented in random directions.” See specification, page 7,
lines 15-18. The subject matter on appeal is directed to a
method for manufacturing a superconducting oxide wire, which
method allows most of the plate-shaped superconducting oxide
particles (which constitutes 50% or more of the
superconducting powder) to have a particular orientation in
the wire. See claim 8 in conjunction with, e.g.,
specification, page 7. This particular orientation is
described as having the C faces of most of the plate-shaped
superconducting particles facing toward the longitudinal axis
