as claimed, and there is no motivation to use the Epstein sensor
in an engine pressure sensor [brief, pages 8-9]. Other than to
note that the thickness of the piezoelectric element would be
obtained through routine experimentation of the routineer, the
examiner has not addressed any of these questions. In our view,
Epstein teaches nothing more than that piezoelectric elements
made from lithium niobate crystal would operate in a high
temperature environment. The examiner has not demonstrated any
evidence in the record as to why the other specific parameters of
the piezoelectric element as recited in claim 1 would have been
obvious to the artisan in view of the applied references.
With respect to the rejections based on Bundy, appellants
argue that Bundy is not a pressure sensor as claimed, there is no
suggestion of a thickness of 0.3-1.5 mm as claimed, the
polarization angle in Bundy is 90 , and there is no motivation too
use the Bundy explosion monitoring device in an engine pressure
sensor [brief, page 9]. Other than to note that the thickness of
the piezoelectric element would be obtained through routine
experimentation of the routineer, the examiner has not addressed
any of these questions. In our view, Bundy teaches nothing more
than that piezoelectric elements made from lithium niobate
crystal would operate in a high temperature environment. The
