electrolyte polymers) in the form of membrane are useful as part
of a corrosion sensor.
Similarly, neither Tomantschger nor Kosek relied upon by the
examiner recognizes that a solid electrolyte polymer membrane can
be effective in detecting or measuring corrosion. Specifically,
both Tomantschger and Kosek are limited to employing a solid
electrolyte polymer membrane for a purpose and a manner
materially different from those described in Homma (i.e.,
detecting gases by contacting the gases (rather than corrosion in
a metal substrate) directly with an electrode, rather than with a
solid electrolyte polymer containing a liquid electrolyte).
Compare, e.g., the Brief, pages 8 and 9 and the Answer, pages 7
and 8. Thus, on this record, we determine that the
examiner has not demonstrated that solid electrolyte polymers in
the form of membrane are useful for the corrosion sensor of the
type described in Homma. The examiner has not supplied
sufficient evidence to show that one of ordinary skill in the art
would have recognized the viability of using a solid electrolyte
polymer membrane in the sensor of the type described in Homma.
It follows that the applied prior art references as a whole would
not have provided sufficient suggestion or motivation to arrive
at the subject matter on appeal.
