Appeal 2007-0953
Application 10/607,466
and demultiplexing, or that such functionality in planar lightwave circuits is
well known in the art. We can say, however, that no such prior art exists on
this record.
For the foregoing reasons, we will not sustain the Examiner’s
rejection of independent claim 10. Likewise, we will not sustain claims 11-
13 which depend therefrom.
CONCLUSION OF LAW
Appellants have established that the Examiner erred in finding that
McGreer discloses a wavelength division multiplexer/demultiplexer where
(1) the input waveguide for inputting a multiplexed optical signal to the
grating is respectively disposed on both sides of the substrate centering on
the AWG, and (2) the output waveguides for outputting single-channel
demultiplexed optical signals are respectively disposed on both sides of the
substrate centering on the AWG as claimed.
DECISION
We have not sustained the Examiner's rejection with respect to all
claims on appeal. Therefore, the Examiner’s decision rejecting claims 10-13
is reversed.
