Appeal No. 1999-0863
Application 08/674,727
to the same ground potential. Thus, the interdigital
electrodes are shorted to each other in the electrical sense.
Claim 17 does not define over this structure. The rejection
of claims 17-19 over Takema is sustained.
Claims 20 and 21
Because the rejections of independent claim 17 over Ruile
and Mitchell have been reversed, the rejections of dependent
claim 20 over Ruile and Mitchell are reversed.
Claim 21 contains the same limitation of "a dummy
electrode, comprising electrically shorted interdigital
electrodes" as claim 17. This limitation is not found in
Ruile and Mitchell, as discussed in connection with claim 17.
Thus, the rejection of claim 21 over Ruile and Mitchell is
reversed.
Claim 20 further recites "wherein said first longitudinal
mode coupling type resonator and said second longitudinal mode
coupling type resonator each generate two resonance
frequencies, wherein a higher resonance frequency of said
first longitudinal mode coupling type resonator is equal to a
lower resonance frequency of said second longitudinal mode
