As for claim 1 , in line 1 ‘an optical modulator coupled to a demodulation circuit’ is indefinite, for it is unclear if the claim covers the combination, an optical modulator and demodulation circuit of ‘an optical modulator coupled to a demodulation circuit ’ or the subcombination, ‘an optical modulator,’ thereby rendering the scope of the claim unclear. Claims 2-8 are rejected by virtue of their dependency from claim 1. As for claim 2 , on lines 1-2 ‘The optical modulator according to claim 1, wherein the optical modulator’ is indefinite, for it is unclear which ‘optical modulator’ is being referred, an optical modulator and the optical modulator of lines 1 and 5-6 of claim 1 or ‘an optical modulator’ of line 11 of claim 1 . As for claim 3 , on lines 1-2 ‘The optical modulator according to claim 1, wherein the optical modulator’ is indefinite, for it is unclear which ‘optical modulator’ is being referred, an optical modulator and the optical modulator of lines 1 and 5-6 of claim 1 or ‘an optical modulator’ of line 11 of claim 1 . As for claim 4 , on line 1 ‘The optical modulator according to claim 1’ is indefinite, for it is unclear which ‘optical modulator’ is being referred, an optical modulator and the optical modulator of lines 1 and 5-6 of claim 1 or ‘an optical modulator’ of line 11 of claim 1 . As for claim 5 , on line 1 ‘The optical modulator according to claim 1’ is indefinite, for it is unclear which ‘optical modulator’ is being referred, an optical modulator and the optical modulator of lines 1 and 5-6 of claim 1 or ‘an optical modulator’ of line 11 of claim 1 . As for claim 6 , on line 1 ‘The optical modulator according to claim 1’ is indefinite, for it is unclear which ‘optical modulator’ is being referred, an optical modulator and the optical modulator of lines 1 and 5-6 of claim 1 or ‘an optical modulator’ of line 11 of claim 1 . As for claim 7 , on line 3 ‘The optical modulator according to claim 1’ is indefinite, for it is unclear which ‘optical modulator’ is being referred, an optical modulator and the optical modulator of lines 1 and 5-6 of claim 1 or ‘an optical modulator’ of line 11 of claim 1 . Allowable Subject Matter 07-43-01 4. Claims 1-8 appear to be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA), 2nd paragraph, set forth in this Office action.
