Pertaining to claim 9, Chen discloses A power supply unit (Abstract, see fig. 1) configured to provide an output power source to a power output panel (copper strips 15, see fig. 3), the power supply unit (transformer 11 + PCB board 1, see fig. 2) comprising: a transformer (11); and an output connection electrode electrically connected (see “X” in the reproduction of Fig. 4 below) between the transformer and the power output panel (15) and configured to transmit the output power source to at least one connector of the power output panel (copper strips 15, see fig. 3). Pertaining to claim 16, Chen discloses, wherein the output connection electrode (see “X” in the reproduction of Fig. 4 above) extends to the power output panel (15) in a first direction (see fig. 3). 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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claims 2 and 10 are rejected under 35 U.S.C. 103 as being unpatentable over Chen (CN 219041650) in view of Liu (CN 214101195 U). Pertaining to claims 2 and 10, Chen discloses wherein the power supply unit (transformer 11 + PCB board 1, see fig. 2) further comprises: a transformer comprising a secondary winding (see paragraph [0020], line 15), wherein a first terminal of the secondary winding is electrically connected to a first terminal of the output connection electrode (see paragraph [0029]). But, Chen doesn’t explicitly teach wherein a second terminal of the output connection electrode is electrically connected to a power pin of the at least one connector. However, Liu teaches wherein a second terminal (12, see fig. 4) of the output connection electrode is electrically connected to a power pin of the at least one connector (see paragraph [0038]). Therefore, At the time of the invention, it would have been obvious before the effective filing date of the claimed invention to a person of ordinary skill in the art to provide a second terminal of the output connection electrode is electrically connected to a power pin of the at least one connector in the device of Chen based on the teachings of Liu in order to focused on electrical efficiency, structural stability, and simplified assembly. Claims 3-7 and 11-15 rejected under 35 U.S.C. 103 as being unpatentable over Chen (CN 219041650) in view of Liu (CN 214101195 U) as applied to claim 2 above, and further in view of Teng et al. (US 8724337 B2). Pertaining to claims 3 and 11, Chen discloses wherein the power supply unit (transformer 11 + PCB board 1, see fig. 2) further comprises: a rectifier element, wherein a second terminal (12 of Liu) of the secondary winding is connected to a ground pin of the at least one connector through the rectifier element (see paragraph [0038 of Liu]) But Chen and Liu do not teach a ground electrode of the main circuit board; and an output capacitor electrically connected between the output connection electrode and the ground electrode of the main circuit board. However, Teng et al. teaches a ground electrode of the main circuit board; and an output capacitor electrically connected between the output connection electrode and the ground electrode of the main circuit board, (see column 4, lines 53-60). Therefore, At the time of the invention, it would have been obvious before the effective filing date of the claimed invention to a person of ordinary skill in the art to provide a ground electrode of the main circuit board; and an output capacitor electrically connected between the output connection electrode and the ground electrode of the main circuit board in the device of Chen based on the teachings of Teng et al. in order provides voltage stabilization, noise suppression (EMI filtering), and safety.
