Appeal No. 1999-2595
Application No. 08/927,106
that a sintering temperature of about 1000°C. causes some diffusion
of nickel into the NGO film (specification, page 9, ll. 23-25), one
of ordinary skill in this art would not have been led to use a
sintering temperature of 1000°C. for a sufficient duration to
promote diffusion in view of the teaching of Han that “phase-pure”
NGO films are desired, with atomically abrupt interfaces between
the substrate and the film (see Han, page 3048, left column, first
full paragraph, and right column, first full paragraph).
For the foregoing reasons, we determine that the combination
of references as proposed by the examiner does not disclose or
suggest all of the limitations of the claimed subject matter on
appeal. Therefore we determine that the examiner has not
established a prima facie case of obviousness. As noted above, the
citation of Woolf ‘360 does not remedy the deficiencies discussed
above. Accordingly, we cannot sustain the examiner’s rejections on
appeal.
