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.
Claim(s) 1, 2 and 7 are rejected under 35 U.S.C. 103 as being unpatentable over Chang et al. (US 2012/0086889 A1) in view of Chan et al. (US 2019/0113208 A1) and Yu et al. (US 2015/0168629 A1).

Response to Arguments
Applicant’s arguments with respect to claim(s) 1-11 have been considered but are moot in view of new grounds of rejection necessitated by applicant’s amendment of independent claim 1 and further consideration of applicant’s arguments. A new reference, Chan et al., teaches the limitations, inter alia, “the plurality of apertures overlapping the circuit board along a normal direction of the circuit board and exposing the first reflective element”..
Claims 2-11 remain rejected based on dependency on a rejected base claim.
