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 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. 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. 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. Claims 3,13,17 are rejected under 35 U.S.C. 103 as being unpatentable over Butta in view of Yamanaka et al (US20180187791A1), hereinafter Yamanaka. Regarding Claim 3, Butta discloses the system of claim 2. Butta does not explicitly disclose wherein each of the plurality of protrusions comprises a through-hole for receiving a fastener configured to engage with the housing of the electric motor (In Butta, 80 is coupled via 12 to Cm). Yamanaka discloses (Figs 3,6) wherein each of the plurality of protrusions (support 24 protrusion where 42 goes through) comprises a through-hole (42 hole) for receiving a fastener (42) configured to engage with the housing (20) of the electric motor (21). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have formed system of Butta with through holes going through protrusions for receiving fastener as taught by Yamanaka in order to position bolts as per design choice to join with motor housing and provide uniform loading of the support and maintain structural integrity. PNG media_image4.png 576 514 media_image4.png Greyscale PNG media_image5.png 594 472 media_image5.png Greyscale Regarding Claim 13, Butta discloses the system of claim 10. Butta further discloses wherein the support (80) is physically coupled to a housing (Cm) of a prime mover (M) via fasteners (80 is fastened to Cm via 12) but does not explicitly disclose extending through through-holes of the plurality of arms. Yamanaka discloses (Fig 3) fasteners (42) extending through through-holes (42 hole) of the plurality of arms (support 24 protrusion where 42 goes through). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have formed support of Butta with through holes going through arms as taught by Yamanaka in order to position bolts as per design choice to provide uniform loading of the support and maintain structural integrity. Regarding Claim 17, Butta discloses the system of claim 16. Butta further discloses wherein the support (80) comprises a plurality of arms (81,82 circumference has many protrusions in Figs 2-3) extending from the opening (Bf2 space within 80) to a location radially outside (82) of an output gear (Gf) but does not explicitly disclose wherein the plurality of arms comprises through-holes configured to receive a plurality of fasteners. Yamanaka discloses (Fig 3) the plurality of arms (support 24 protrusion where 42 goes through) comprises through-holes (42 hole) configured to receive a plurality of fasteners (42). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have formed system of Butta with through holes going through arms as taught by Yamanaka in order to position bolts as per design choice to provide uniform loading of the support and maintain structural integrity. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Yu (US20210229548A1) discloses coaxial structure of input and output gear (Fig 4).
