Appeal No. 95-4863
Application 07/865,993
would otherwise be combined with the teachings of the primary
references.
With respect to the rejections based on Gürich,
appellants argue that there is no suggestion of a thickness of
0.3-1.5 mm as claimed, and there is no motivation to use the pair
of Gürich shearing force type sensors for the single transverse
force type sensor in an engine pressure sensor such as suggested
by Sonderegger or Lukasiewicz [brief, pages 11-12]. 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 the question of why the piezoelectric
elements of Gürich which measure shearing forces would have been
substituted for the single element of the primary references
which measure transverse forces. The examiner has not
demonstrated any evidence in the record as to why the Gürich
piezoelectric element would have been used in the primary
references, or if used, why it would have the properties recited
in claim 1.
In summary, no combination of either of the primary
references with any of the secondary references teaches the
invention as recited in appellants’ claims, nor is there any
suggestion for combining the teachings of the references other
