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.

Response to Arguments
Applicant’s arguments with respect to independent claim 1 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument.
Applicant argues on pages 1-6, Section: Rejections Under 35 U.S.C. §103, in remarks filed March 23, 2026 that the current prior art of record does not teach the amendments to independent claim 1. Examiner agrees with Applicant; However, after a new line of search and consideration of the prior art the amended limitations of independent claim 1 can be overcome by newly cited sources Ota et al. (US 20200161499 A1), and Xu (US 20190277455 A1).
Applicant argues that their specific architecture of the present application is different than that of the prior art of record. Examiner agrees with Applicant; However this does not place the application in condition for allowance. Applicant has not presented any criticality of the specific limitation and how their arrangement contains any new and/or unexpected results. See MPEP 2144.04 (VI)(C) Rearrangement of Parts.
Examiner proposes that the newly cited sources Ota et al. (US 20200161499 A1), and Xu (US 20190277455 A1), in combination, can overcome the amended limitations of independent claim 1. One of ordinary skill in the art would be motivated to combine Ota et al. and Xu with primary reference Kim et al. (KR 20200009921 A), for the purpose of increasing the radiant flux of light emitted by the light source, high reflectivity and improving light extraction efficiency.
Applicant argues on page 6, Section: Rejections Under 35 U.S.C. §103, in remarks filed March 23, 2026 that dependent claims 2-6 and 8-12, which depend on independent claim 1, should be in condition for allowance. Examiner disagrees with Applicant for at least the reasons mentioned above.
In summary, the amended limitations of independent claim 1 can be overcome by newly cited sources Ota et al. (US 20200161499 A1), and Xu (US 20190277455 A1). All claims directly or indirectly dependent on independent claim 1 are also rejected for at least the reasons mentioned above.
