Appeal No. 2001-0089
Application 08/975,469
that the annular plastic ring be fabricated in situ within the
retaining groove.
Turning now to the applied Hensley patent (Figures 1 and
3), we recognize the positioning of an unnumbered member in a
groove at the upper end of the pole piece 18. Additionally,
we find that the written specification of the patent does not
provide any description of this member at all.
The examiner’s view is that the claimed method would have
been obvious from the Hensley document. We disagree.
Simply stated, the proffered evidence clearly fails to
provide any suggestion whatsoever for the step of forming an
annular plastic ring in a retaining groove in an inlet end of
an electromagnetic valve, as now claimed. Since, as
indicated, the examiner has not provided adequate evidence
supporting the obviousness of the claimed invention, the
rejection must be reversed.
REMAND TO THE EXAMINER
