DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claim Rejections - 35 USC § 102
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
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.
Claim(s) 1 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Akiyama (CN 201680054805 A).
With respect to claim 1, Akiyama discloses the light source device (see fig.9), comprising: a first light source module (see 110 in fig.9) configured to output a first light beam; a second light source module (see 16 in fg.9) configured to output a second light beam, wherein etendue of the first light beam (see the laser beam of 110 in fig.9) is smaller than etendue of the second light beam (see disclosed by the operation of the wavelength converter 16 in fig.9); a polarization conversion system (127 in fig.9) configured to receive the first light beam and the second light beam and perform polarization conversion on at least one of the first light beam and the second light beam (see the operation of 127 in fig.9); and an etendue increasing module (18 in fig.9) provided on a light path between the first light source module (see 10 in fig.9) and the polarization conversion system (see 127 in fig.9) and configured to increase the etendue of the first light beam (light beam of 10 in fig.9) and does not increase the etendue of the second light beam, a part of the first light beam (see the beam reflected by 14) is guided to a wavelength conversion device to generate the second light beam (see the beam produced by 16).
Response to Arguments
Applicant’s arguments with respect to claim(s) 1 have been considered but are moot because the new ground of rejection does not rely on the previous rejections or interpretations of references applied in the prior rejection of record for any teaching or matter specifically challenged in the argument.
