The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.

Regarding claim 1, Komatsu teaches (Figs. 1-4) A wavelength detection device comprising: waveguides (23) configured to guide lights; a multiplexer unit (30) configured to multiplex lights respectively guided through the waveguides and having wavelengths different (lamda 1-4) from one another; a filter unit (33 – see also col. 5, line 19-22, 52-60, and col. 6) to which light output from the multiplexer unit is input, the filter unit having a property of having light transmittance that changes according to wavelength; and a detection unit configured to detect intensity of light output from the filter unit, wherein the waveguides, the multiplexer unit, and the filter unit are included in a planar light wave circuit (col. 5, lines 32-35).
Regarding claim 3, Komatsu teaches the multiplexer unit includes a wavelength division multiplexing (28) coupler.
Regarding claim 5, Komatsu teaches the filter unit includes filters having different properties for transmittance in relation to wavelength.
