Response to Arguments Applicant’s arguments with respect to claim(s) 1-20 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. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 7-8 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 7 recites “wherein the base, wherein the first prong, the second prong, the first conductive lip, and the second conductive lip are orthogonal to the center portion, etc.” It is unclear from this language whether the base is claimed to be orthogonal to the portions; the second ‘wherein’ should be deleted.

Claim Rejections - 35 USC § 103 Claims 2 and 16-17 are rejected under 35 U.S.C. 103 as being unpatentable over TONG in view of BAEK (US 20220376581 previously disclosed). Regarding claim 2, TONG discloses the electrical connector of claim 1, However, TONG does not disclose the plurality of plugs are a first-phase plug, a second-phase plug, and a third-phase plug, wherein the plurality of sockets are a first-phase socket, a second-phase socket, and a third-phase socket, wherein the first-phase plug, the second-phase plug, and the third-phase plug are connected to the first-phase socket, the second-phase socket, and the third-phase socket, respectively. BAEK discloses a plurality of plugs 141 are a first-phase plug, a second-phase plug, and a third-phase plug, wherein a plurality of sockets 320 are a first-phase socket, a second-phase socket, and a third-phase socket, wherein the first-phase plug, the second-phase plug, and the third-phase plug are connected to the first-phase socket, the second-phase socket, and the third-phase socket, respectively (see para [0039]). It 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 to provide the electrical connector of TONG with first-, second-, and third-phase plugs and sockets similar to that of BAEK. A person having ordinary skill in the art to which the claimed invention pertains would have been motivated to make such modification in order to provide a three-phase induction motor with coils drawn out from the drive motor which is easily assembled as taught by BAEK (see para [0011]) Regarding claim 16, TONG discloses the electric motor of claim 15. However, TONG does not disclose the electric motor is a three-phase electric motor, the plurality of plugs are a first-phase plug, a second-phase plug, and a third-phase plug, the plurality of sockets are a first-phase socket, a second-phase socket, and a third-phase socket, the first-phase plug, the second-phase plug, and the third-phase plug are connected to the first-phase socket, the second-phase socket, and the third-phase socket, respectively. BAEK discloses a plurality of plugs 141 are a first-phase plug, a second-phase plug, and a third-phase plug, a plurality of sockets 320 are a first-phase socket, a second-phase socket, and a third-phase socket, the first-phase plug, the second-phase plug, and the third-phase plug are connected to the first-phase socket, the second-phase socket, and the third-phase socket, respectively (see para [0039]). It 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 to provide the electrical connector of TONG with first-, second-, and third-phase plugs and sockets similar to that of BAEK. A person having ordinary skill in the art to which the claimed invention pertains would have been motivated to make such modification in order to provide a three-phase induction motor with coils drawn out from the drive motor which is easily assembled as taught by BAEK (see para [0011]) Regarding claim 17, TONG in view of BAEK teaches the electric motor of claim 16, TONG discloses the busbar 214 comprising a plurality of bus pins 1522 and a neutral bus 14, wherein the plurality of bus pins 1522 are connected to the plurality of sockets 326, wherein the winding 6 is connected to the plurality of bus pins 1522 and the neutral bus 14, wherein TONG in view of BAEK teaches the plurality of bus pins 1522 comprise one or more first-phase bus pins, one or more second-phase bus pins, and one or more third-phase bus pins. Claim 18 is rejected under 35 U.S.C. 103 as being unpatentable over TONG in view of BAEK as applied to claim 17 above, and further in view of KIM (US 20200106328). Regarding claim 18, TONG in view of BAEK discloses the electric motor of claim 17, However, TONG in view of BAEK does not teach the winding is a hairpin winding. It 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 to provide the motor of TONG in view of BAEK with a hairpin winding similar to that of KIM A person having ordinary skill in the art to which the claimed invention pertains would have been motivated to make such modification in order to provide a motor with three-phase bus bars that protects against unintentional discharge and enhances cooling efficiency and may prevent performance of the motor from being degraded, as taught by KIM (see para [0012] and [0041]). Claim 8 is rejected under 35 U.S.C. 103 as being unpatentable over TONG in view of CHAMBERLIN US 20130175853. Regarding claim 8, TONG discloses the electrical connector of claim 7. However, each of the plurality of plugs 222 are not co-planar (see Fig. 18A, they are nearly co-planar in this embodiment). PNG media_image4.png 438 450 media_image4.png Greyscale CHAMBERLIN discloses an electrical connector with each of a plurality of plugs 62/63/64 are co-planar (para [0044]). It 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 to provide the electrical connector of TONG with each of a plurality of plugs are co-planar, similar to CHAMBERLIN. A person having ordinary skill in the art to which the claimed invention pertains would have been motivated to make such modification in order to provide flush engagement surfaces allowing each prong to bend inwardly during installation and then snap back outwardly into engagement as taught by CHAMBERLIN (para [0044]). Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action. The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
