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. Claim(s) 7-8 is/are rejected under 35 U.S.C. 103 as being unpatentable over Deh in view of Redmann (US 2010/0283426). Regarding claim 7, Deh fails to teach the charging system further comprises a fused disconnect switch disposed between an output of the one or more power lines and the one or more transformers. PNG media_image3.png 750 1224 media_image3.png Greyscale However, Redmann further discloses the charging system further comprises a fused disconnect switch (fig. 5, element 222, 532, 534 and ¶¶ 0048, 0053; an inadvertent draw of excess current through charging circuit trips breaker rather than blowing fuse 222) disposed between an output of the one or more power lines (fig. 5, element 108) and the one or more transformers. It would have been obvious to one skilled in the art before the effective filing date of the claimed invention to modify Deh to incorporate with the teaching of Redmann by including a fuse and a circuit break in the system, because it would be advantageous to protect the electrical components from short circuit and prolong the service life of the whole system. Although Deh in view of Redmann does not disclose the location of the fused disconnect switch, one ordinary skilled in the art would recognize that the fuse and circuit break can be disposed between an output of the power line and the transformer, because it would be advantageous to protect the transformer from short circuit and further improve system stability. Regarding claim 8, Deh in view of Redmann fails to disclose wherein the fused disconnect switch is a 50 Amperes fusible disconnect switch. However, to choose a 50 Amperes fusible disconnect switch, absent any criticality, is only considered to be the “optimum” value of the fusible disconnect switch, as stated above, that a person having ordinary skill in the art would have been able to determine using routine experimentation based, among other things, on the desired accuracy and since it has been held that discovering an optimum value of a result effective variable involves only routine skill in the art. See In re Boesch, 205 USPQ 215 (CCPA 1980) and MPEP 2144.04 and 2144.05. Claim(s) 9-10, 12-13 is/are rejected under 35 U.S.C. 103 as being unpatentable over Deh (US Pub 2021/0170894). Regarding claim 9, Deh discloses wherein the one or more transformers (¶¶ 0023, 0027), but fails to disclose the transformer can be selected from one of: a step-up transformer, a step-down transformer, or an isolation transformer. One skilled in the art would recognize that the transformer of Deh is a step-down transformer because the sole purpose of the pole-mounted distribution transformer is to step-down that high primary voltage to safe secondary voltage for end-use requires only routine skill. Regarding claim 10, Deh fails to disclose wherein the one or more transformers corresponds to a 277/240 volts transformer. However, to choose a 277/240 volts transformer, absent any criticality, is only considered to be the “optimum” value of the fusible disconnect switch, as stated above, that a person having ordinary skill in the art would have been able to determine using routine experimentation based, among other things, on the desired accuracy and since it has been held that discovering an optimum value of a result effective variable involves only routine skill in the art. See In re Boesch, 205 USPQ 215 (CCPA 1980) and MPEP 2144.04 and 2144.05. Regarding claim 12, although Deh does not expressly disclose wherein the enclosure is formed of one of: a metal, a wood, or a plastic, these limitations with regard to the material of the enclosure/housing of the charging assembly, does not show any criticality, is only considered to be an obvious modification of the housing, taught by Deh, since it appears to the Examiner that selecting a specific material for the enclosure is nothing more than one of numerous materials that a person having ordinary skill in the art will find obvious to provide. In this case to lower the manufacturing cost of the charging assembly. Regarding claim 13, although Deh does not disclose wherein the enclosure comprises one or more ventilation vents, the enclosure includes one or more ventilation vents claimed by applicant, absent any criticality, is considered to be nothing more than a choice of engineering skill, choice or design because 1) neither non-obvious nor unexpected results, i.e., results which are different in kind and not in degree from the results of the prior art, will be obtained as long as the charging assembly is able to supply power without interruption, as already suggested by Deh, 2) the enclosure includes one or more ventilation vents to cool down the internal components by Applicant is considered to be nothing more than the use of one of numerous and well known alternate types of cooling method that a person having ordinary skill in the art would have been able to provide using routine experimentation in order to reduce the size of the charging assembly and further lower the manufacturing cost.
