Office Action

§102 §103
DETAILED ACTION The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . 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 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. Response to Amendment/Restriction Applicant’s election without traverse of Species II and Claims 1-13 in the reply filed on October 30, 2025 is acknowledged. Thus, Claims 14-20 is withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected invention. Election was made without traverse in the reply filed on October 30, 2025. Specification The title of the invention is broad and not descriptive. A new title is required that is clearly indicative of the invention to which the claims are directed. Claim Rejections - 35 USC § 102 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. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claim(s) 1-3, 5, and 7-13 are rejected under 35 U.S.C. 102(a)(1)(2) as being anticipated by KR-20210158825-A to Park (“Park”).

As to claim 9, Park further discloses wherein when viewed from a front side, a width of the tilting module (110, 180) in a left-right direction is smaller than a width of the main light emitting module (two outer 140 not facing 10) in the left-right direction (See Fig. 1). As to claim 10, Park discloses further comprising a controller for controlling at least one of the main light emitting module (two outer 140 not facing 10), the first auxiliary light emitting module (20 on 150), and the second auxiliary light emitting module (20 on 160), or controlling the rotation driving unit (110, 180) to rotate the tilting frame (one inner 140 facing 10) (See Fig. 1, ¶ 0035, ¶ 0064). As to claim 11, Park further discloses wherein the controller controls the tilting module (110, 180) so that the tilting frame (one inner 140 facing 10) is positioned in a first position state in which a front surface of the first frame part (150) and a front surface of the second frame part (160) each form an inclination angle with a front surface (one surface of 150/160) of the main light emitting module (two outer 140 not facing 10), a second position state in which one of the front surface of the first frame part (150) and the front surface of the second frame part (160) is parallel to the front surface (one surface of 150/160) of the main light emitting module (two outer 140 not facing 10), or a third position state in which the other one of the front surface of the first frame part (150) and the front surface of the second frame part (160) is parallel to the front surface of the main light emitting module (two outer 140 not facing 10) (See Fig. 2) (Notes: the three positions include a 0 or 180 degree/coplanar 150 and 160 such that the parallel surfaces are formed). As to claim 12, Park further discloses wherein in the first position state, the inclination angle between the front surface of the first frame part (150) and the front surface (one surface of 150/160) of the main light emitting module (two outer 140 not facing 10) and the inclination angle between the front surface of the second frame part (160) and the front surface (one surface of 150/160) of the main light emitting module (two outer 140 not facing 10) are smaller than an angle formed by the front surface of the first frame part (150) and the front surface of the second frame part (160) (See Fig. 2) (Notes: the parallel surfaces between the front surfaces form a smaller angle than the angle between the front surfaces of the first and second frame parts). As to claim 13, Park further discloses wherein in the first position state, a connection portion (142) of the first frame part (150) and the second frame part (160) is protruded forward or retracted backward by a predetermined distance from an imaginary reference line extending from the front surface (one surface of 150/160) of the main light emitting module (two outer 140 not facing 10) to the connection portion (142) of the first frame part (150) and the second frame part (160) (See Fig. 2). 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 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. Claim(s) 4 and 6 are rejected under 35 U.S.C. 103 as being unpatentable over KR-20210158825-A to Park (“Park”) as applied to claims 2 and 5 above, and further in view of U.S. Patent Application Publication No. 2019/0229097 A1 to Takeya et al. (“Takeya”). The teaching of Park has been discussed above. As to claim 4, Park in view of Takeya further discloses wherein the one or more main light emitting elements (20/150) include a plurality of main light emitting structures (20/150) and a main light emission electrode (170p, 170q), wherein each of the plurality of main light emitting structures (20/150) includes one or more conductive-type semiconductor layer (153, 157) and an electrode layer (159p, 159q), and wherein the main light emission electrode (170a, 170q) is electrically connected to the electrode layer (159p, 159q) included in each of the plurality of main light emitting structures (20/150) (See Takeya Fig. 2, Fig. 9, ¶ 0105, ¶ 0115, ¶ 0131-¶ 0134, ¶ 0188, ¶ 0195, ¶ 0196, ¶ 0305) such that the well-known light emitting structures connected in parallel emit desire light. As to claim 6, Park in view of Takeya further discloses wherein the one or more first auxiliary light emitting elements (20/150) are configured to generate light of a different wavelength from that of one or more main light emitting elements (20/150) included in the main light emitting module (two outer 140 not facing 10), or configured to have a different lamination structure from that of the one or more main light emitting elements (20/150) (See Takeya Fig. 2, Fig. 9, ¶ 0105, ¶ 0115, ¶ 0131-¶ 0134, ¶ 0188, ¶ 0195, ¶ 0196, ¶ 0305) such that desired wavelengths are emitted as desired and application/direction specific.
