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 § 103
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 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.
Claims 3-5, 9-13, 16 and 18-19 are rejected under 35 U.S.C. 103 as being unpatentable over Aphek et al. (US 2008/0291954) in view of Amit et al. (US 2016/0131843).
Regarding claim 3, Aphek discloses, a method for aligning (Figs. 3-4B and 5B) a light source (200) comprising a plurality of lasers (Para. 0008) spaced in an arrangement, each of the lasers operable to emit a beam of light (B’1, B’2, B’3), the method comprising:
centering and collimating (Para. 0062) each of the beams of light by positioning one or more lenses (Para. 0062 and L3, L6, L9) in an optical path of the beam of light and fixing a position of the one or more lenses (Para. 0065-0066);
positioning mirrors to redirect the beams of light to provide a closely spaced array of parallel beams of light (Para. 0065-0066) and fixing positions of the mirrors (Para. 0065-0066).
Aphek does not explicitly disclose the mirrors are permanently fixed, after the positioning of the mirrors.
Amit teaches, from the same field of endeavor that in a method for aligning that it would have been desirable to make the mirrors are permanently fixed, after the positioning of the mirrors (Para. 0054, lines 18-29).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to make the mirrors are permanently fixed, after the positioning of the mirrors as taught by the method for aligning of Amit in the method for aligning of Aphek since Amit teaches it is known to include this feature in a method for aligning for the purpose of providing an accurately and correctly aligned mirror with long term stability and reduced alignment errors.
Furthermore, KSR rationale – combining prior art elements according to known methods to yield predictable results - offers that it would have been desirable to provide the mirror of Aphek to be permanently fixed would have been obvious to one of ordinary skill in the art, view the teachings of Amit, since all claimed elements were known in the prior art and one skill in the art could have combined the elements as claimed by known elements with no change in their respective functions, and the combination would have yielded nothing more than predictable results to one of ordinary skill in the art at the time of the invention, i.e., one skill in the art would have recognized that permanently fixing the mirrors as used in Amit would allow the mirrors in the method for aligning of Aphek to be permanently aligned and to maintain the position of the mirrors to prevent additional alignment and mounting inaccuracies.
Regarding claim 4, Aphek in view of Amit discloses and teaches as set forth above, and Aphek further discloses, positioning the mirrors comprises reducing a spacing between adjacent ones of the beams of light emitted from the plurality of lasers (Para. 0065-0066 and see Fig. 5B).
Regarding claim 5, Aphek in view of Amit discloses and teaches as set forth above, and Aphek further discloses, positioning the mirrors to clip edges of the beams of light emitted from the plurality of lasers (Para. 0065-0066 and see Fig. 5B).

Regarding claim 10, Aphek in view of Amit discloses and teaches as set forth above, but does not explicitly disclose shimming the flexible structure into place.
The Examiner points out that it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to include shimming the flexible structure into place for the purpose of effectively and accurately holding the flexible structure in the correct position.
Regarding claim 11, Aphek discloses, applying a settable material to fix the positions of the one or more lenses (Para. 0062, 0065-0066 and Figs. 4A-B and 5B).
Aphek does not explicitly disclose the mirrors are permanently fixed.
Amit teaches, from the same field of endeavor that in a method for aligning that it would have been desirable to make the mirrors are permanently fixed (Para. 0054, lines 18-29).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to make the mirrors are permanently fixed as taught by the method for aligning of Amit in the method for aligning of Aphek since Amit teaches it is known to include this feature in a method for aligning for the purpose of providing an accurately and correctly aligned mirror with long term stability and reduced alignment errors.
Furthermore, KSR rationale – combining prior art elements according to known methods to yield predictable results - offers that it would have been desirable to provide the mirror of Aphek to be permanently fixed would have been obvious to one of ordinary skill in the art, view the teachings of Amit, since all claimed elements were known in the prior art and one skill in the art could have combined the elements as claimed by known elements with no change in their respective functions, and the combination would have yielded nothing more than predictable results to one of ordinary skill in the art at the time of the invention, i.e., one skill in the art would have recognized that permanently fixing the mirrors as used in Amit would allow the mirrors in the method for aligning of Aphek to be permanently aligned and to maintain the position of the mirrors to prevent additional alignment and mounting inaccuracies.
Regarding claim 12, Aphek in view of Amit discloses and teaches as set forth above, and Aphek further discloses, the settable material comprises epoxy, glue or solder (Para. 0062, 0065-0066 and Figs. 4A-B and 5B).
Regarding claim 13, Aphek in view of Amit discloses and teaches as set forth above, and Aphek further discloses, positioning a diffraction grating in an optical path of the lasers to produce an alignment pattern and adjusting alignment of the closely spaced array of parallel light beams using the alignment pattern (Para. 0053).
Regarding claim 16, Aphek in view of Amit discloses and teaches as set forth above, and Aphek further discloses, positioning one or more additional lenses or mirrors to expand or contract the beam of light emitted from a corresponding one of the lasers (see 430A, B).
