Appeal No. 1999-0863
Application 08/674,727
The reflectors 13 and 23 in Ehata have electrically
shorted interdigital electrodes and are part of first and
second longitudinal mode coupling type resonators. Appellant
provides no arguments why a reflector electrode cannot be a
"dummy" electrode and, absent an argument of error, we will
not provide any special interpretation of the term "dummy."
The rejection of claims 17-19 over Ehata is sustained.
The reflector structure 6 illustrated in Ruile, Fig. 1,
and the reflector structures R1, R2 in Mitchell, Fig. 1, do
not have electrically shorted interdigital electrodes.
Evidently not all grating reflectors have electrically shorted
interdigital electrodes. The rejections of claims 17-19 over
Ruile and Mitchell are reversed.
The Examiner finds that Fig. 3 of Takema shows "at least
one of said interdigital electrodes is a 'dummy' electrode,
comprising shorted interdigital electrodes (3)" (FR6).
Appellant does not address the Examiner's finding in the brief
or reply brief.
The two grounded interdigital electrodes 2 in Takema,
positioned one above the other in Fig. 2 and positioned on a
diagonal line in Fig. 3, have both sets of fingers connected
