Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
The factual inquiries set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b) (2) (C) for any potential 35 U.S.C. 102(a) (2) prior art against the later invention.

Allowable Subject Matter
2. Claims 2,3,4,5,6,7,11,12 and 13 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
3. The following is an examiner’s statement of reasons for objecting the claims as allowable subject matter:
As to claim 2, prior art of record does not teach or suggest the limitation mentioned within claim 2: “ … first modulator includes: a second beam splitter configured to reflect part of an optical signal reflected from the first beam splitter and incident through the second optical path on a second-first optical path and transmit a remaining part of the optical signal to a second-second optical path; a first phase modulator configured to modulate a phase of an optical signal incident from the second beam splitter through the second-first optical path; a second phase modulator configured to modulate a phase of an optical signal incident from the second beam splitter through the second-second optical path; and a third beam splitter configured to receive an optical signal incident from the first phase modulator and an optical signal incident from the second phase modulator.”
As to claim 3, prior art of record does not teach or suggest the limitation mentioned within claim 3: “… an optical signal delay part configured to delay an optical signal transmitted from the first beam splitter and incident through the third optical path for a predetermined period of time and then emits the optical signal; a fourth beam splitter configured to transmit part of an optical signal incident through the optical signal delay part on a third-first optical path and reflect a remaining part of the optical signal to a third-second optical path; a third phase modulator configured to modulate a phase of an optical signal incident from the fourth beam splitter through the third-first optical path; a fourth phase modulator configured to modulate a phase of an optical signal incident from the fourth beam splitter through the third-second optical path; and a fifth beam splitter configured to receive an optical signal incident from the third phase modulator and an optical signal incident from the fourth phase modulator.”
As to claim 4, prior art of record does not teach or suggest the limitation mentioned within claim 4: “ … phase modulation values of the first phase modulator and the second phase modulator provided in the first modulator, and the third phase modulator and the fourth phase modulator provided in the second modulator, are controlled such that intensity or a phase of an optical signal incident on the polarization splitter-rotator from the second modulator is modulated with a time difference relative to an optical signal incident on the polarization splitter-rotator from the first modulator.”
As per claims 5,6 and 7, Claims 5,6 and 7 depend on objected allowable claim 4, therefore the following claim 5,6 and 7 are considered objected allowable over prior art of record.
As to claim 11, prior art of record does not teach or suggest the limitation mentioned within claim 11: “ … a second beam splitter configured to reflect part of an optical signal reflected from the polarization splitter-rotator and incident on a second-first optical path through the second optical path and transmit a remaining part of the optical signal to a second-second optical path; a first phase modulator configured to modulate a phase of an optical signal incident from the second beam splitter through the second-first optical path; a second phase modulator configured to modulate a phase of an optical signal incident from the second beam splitter through the second-second optical path; and a third beam splitter configured to receive an optical signal incident from the first phase modulator and an optical signal incident from the second phase modulator.”
As to claim 12, prior art of record does not teach or suggest the limitation mentioned within claim 12: “ … a fourth beam splitter configured to transmit part of an optical signal incident from the polarization splitter-rotator through the second optical path to a third-first optical path and reflect a remaining part of the optical signal to a third-second optical path; a third phase modulator configured to modulate a phase of an optical signal incident from the fourth beam splitter through the third-first optical path; a fourth phase modulator configured to modulate a phase of an optical signal incident from the fourth beam splitter through the third-second optical path; a fifth beam splitter configured to receive an optical signal incident from the third phase modulator and an optical signal incident from the fourth phase modulator; and an optical signal delay part configured to delay an optical signal emitted from the fifth beam splitter for a predetermined period of time.”
As to claim 13, prior art of record does not teach or suggest the limitation mentioned within claim 13: “ … phase modulation values of the first phase modulator and the second phase modulator provided in the first modulator, and the third phase modulator and the fourth phase modulator provided in the second modulator, are controlled such that intensity or a phase of an optical signal incident on the polarization splitter-rotator from the second modulator is modulated with a time difference relative to an optical signal incident on the polarization splitter-rotator from the first modulator.”
