Office Action

§103
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Information Disclosure Statement The information disclosure statement (IDS) submitted on 09/17/2025 is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. Response to Arguments Applicant’s arguments/amendments, see arguments filed 10-28-2025, with respect to the rejection(s) of claim(s) 1-18 under USC 103a have been fully considered and are persuasive. Claim 1 has been amended, Therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made in view of , Hiraike which teaches the new added limitation of claim 1 and teaches the division region is a gap (18) between each of the plurality of strand wires (20). Therefore, it would have been obvious to one with ordinary skill in the art before the effective filling date of the invention to modify the strand wires wherein teach the division region is a gap between each of the plurality of strand wires as suggested by Hiraike to reduce proximity effect (Hiraike, P[0007]). Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Acknowledgment is made of applicant’s claim for foreign priority under 35 U.S.C. 119 (a)-(d). Inventorship This application currently names joint inventors. In considering patentability of the claims under pre-AIA 35 U.S.C. 103(a), the examiner presumes that the subject matter of the various claims was commonly owned at the time any inventions covered therein were made absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and invention dates of each claim that was not commonly owned at the time a later invention was made in order for the examiner to consider the applicability of pre-AIA 35 U.S.C. 103(c) and potential pre-AIA 35 U.S.C. 102(e), (f) or (g) prior art under pre-AIA 35 U.S.C. 103(a). 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. 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 of this title, 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. The factual inquiries set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claim 1-7 are rejected under 35 U.S.C. 103 as being unpatentable over Trimmel et al. (US PG Pub 20140049352 hereinafter “Trimmel”) in view of Hiraike (JP 2014096349 hereinafter “Hiraike”). Re-claim 1, Trimmel discloses a coil wire rod (4), comprising: a conductor (12) formed of a conductive material (conductor that conduct electricity is made from conductive material) having a uniform outer peripheral shape (12), and extending in a direction of an axis (axis of 11, see Fig.5), wherein the conductor is divided by a division region (annotated Fig.5) having a radial shape around the axis in a cross-sectional view orthogonal (crosses the axis) to the direction of the axis and includes a plurality of stranded wires (11, annotated Fig.5) each extending in the direction of the axis (annotated Fig.2), and the division region is twisted about the axis toward the direction of the axis in at least a part in the direction of the axis (annotated Fig.2), Examiner takes official notice that a conductor conducting electricality is formed of conductive material, therefore Trimmel wire that conduct electricity is made of conductive material which conducts electrical current.

However, Hiraike teaches the division region is a gap (18) between each of the plurality of strand wires (20). Therefore, it would have been obvious to one with ordinary skill in the art before the effective filling date of the invention to modify the strand wires wherein teach the division region is a gap between each of the plurality of strand wires as suggested by Hiraike to reduce proximity effect (Hiraike, P[0007]). PNG media_image4.png 483 318 media_image4.png Greyscale PNG media_image5.png 271 334 media_image5.png Greyscale Re-claim 2, Trimmel discloses the coil wire rod according to claim 1, wherein at least one corner (13) facing an outer periphery side with respect to the axis of outside surfaces of the plurality of stranded wires (at least 11) forms an arc shape (13 is arc shaped) when viewed from the direction of the axis (direction of looking at it from front, in Fig.5). Re-claim 3, Trimmel discloses the coil wire rod according to claim 1, wherein at least one corner facing an inner periphery side (annotated fig.6) with respect to the axis of outside surfaces of the plurality of stranded wires (11) forms an arc shape (annotated fig.6, inside of the cables strand in the inside has corner arc shape, se fig.6) when viewed from the direction of the axis. Re-claim 4, Trimmel discloses the coil wire rod according to claim 1, wherein at least one corner facing an outer periphery side with respect to the axis of outside surfaces of the plurality of stranded wires forms a flat shape (annotated Fig.6, at least one corner facing the outside surfaces) expanding in a direction orthogonal to a radial direction with respect to the axis when viewed from the direction of the axis (annotated Fig.6, showing corner at outside surface to be orthogonal to the radial direction, which is the up and down direction in fig.6, any direction is interpreted as radial the other direction is orthogonal to the direction defined, so a line crossing radial direction is orthogonal). Re-claim 5, Trimmel discloses the coil wire rod according to claim 1, wherein at least one corner facing an inner periphery side with respect to the axis of outside surfaces of the plurality of stranded wires forms a flat shape expanding in a direction orthogonal to a radial direction with respect to the axis when viewed from the direction of the axis (see annotated fig.5, any direction could be radial, in this case infig.5 up and down is radial, then crossing is orthogonal direction). Re-claim 6, Trimmel as modified discloses the coil wire rod according to claim 1, wherein a recessed groove (annotated Fig.5) extending in the direction of the axis is formed in a part of an outside surface of the conductor (12, see fig.5). Re-claim 7, Trimmel as modified disclose the coil wire rod according to claim 6, wherein the recessed groove (annotated Fig.5) has an asymmetric cross-sectional shape with reference to a diametrical direction with respect to the axis (annotated Fig.6). Claims 9-18 are rejected under 35 U.S.C. 103 as being unpatentable over Trimmel in further view of Kozo (Japanese Patent Publication JP2008147062a hereinafter “Kozo”). Re-claim 9, Trimmel discloses coils including the coil wire rod according to claim 1 at least one corner (13) facing an outer periphery side with respect to the axis of outside surfaces of the plurality of stranded wires (11) is substantially cut out (curved, is cut out, or at least as described in disclosure, curved strand is cut out, see Fig.5) when viewed from the direction of the axis. Trimmel fails to explicitly teach a stator, comprising: a yoke annular around a center axis; a plurality of teeth protruding inward in a radial direction from an inside surface of the yoke and arrayed at intervals in a circumferential direction; and including the coil wire rod wound around the teeth, wherein the teeth include a tooth body connected to the inside surface of the yoke and extending in a radial direction and a flange portion overhanging in a circumferential direction from an end portion inward in the radial direction of the tooth body, and in the coil wire rod located at a connection portion between the tooth body and the flange portion of a plurality of the coil wire rods included in the coils, at least one corner facing an outer periphery side with respect to the axis of outside surfaces of the plurality of stranded wires is cut out when viewed from the direction of the axis. Kozo teaches a stator (100), comprising: a yoke (20,23b) annular around a center axis (p); a plurality of teeth (23) protruding inward in a radial direction from an inside surface of the yoke (see fig.5b) and arrayed at intervals in a circumferential direction (see fig.5b); and including the coil wire rod (21,24,10a,10b) wound around the teeth (23a), wherein the teeth (23a,23c) include a tooth body (23a) connected to the inside surface of the yoke (23b) and extending in a radial direction (see fig.5b) and a flange portion (23c) overhanging in a circumferential direction from an end portion inward in the radial direction of the tooth body (23a, 23c is circumferentially extending) , and in the coil wire rod (11, 10a,10b,) located at a connection portion between the tooth body (23a) and the flange portion (23c) of a plurality of the coil wire rods included in the coils (11) , at least one corner (at least corner of 10a, 10b) facing an outer periphery side with respect to the axis of outside surfaces of the plurality of stranded wires (11, 10a,10b, wire strand) is cut out (10a,10b are convex and concave portions) when viewed from the direction of the axis (see fig.5a). Therefore, it would have been obvious to one with ordinary skill in the art before the effective filling date of the invention to modify the electrical motor of Trimmel wherein the motor has a stator, comprising: a yoke annular around a center axis; a plurality of teeth protruding inward in a radial direction from an inside surface of the yoke and arrayed at intervals in a circumferential direction; and including the coil wire rod wound around the teeth, wherein the teeth include a tooth body connected to the inside surface of the yoke and extending in a radial direction and a flange portion overhanging in a circumferential direction from an end portion inward in the radial direction of the tooth body, and in the coil wire rod located at a connection portion between the tooth body and the flange portion of a plurality of the coil wire rods included in the coils, at least one corner facing an outer periphery side with respect to the axis of outside surfaces of the plurality of stranded wires is cut out when viewed from the direction of the axis as suggested by Kozo to provide an improved motor device with aligned winding with high accuracy as suggested in( Kozo, Page-8, P[13,14]).

Trimmel teaches the coil where at least one corner (13) facing an outer periphery side with respect to the axis of outside surfaces of the plurality of stranded wires (11) forms an arc shape (13 is arc shape) when viewed from the direction of the axis (see fig.6, fig.5, fig.4). Trimmel fails to explicitly teach wherein in the coil wire rod located at a connection portion between the tooth body and the flange portion of the plurality of the coil wire rods included in the coils, at least one corner facing an outer periphery side with respect to the axis of outside surfaces of the plurality of stranded wires forms an arc shape when viewed from the direction of the axis. However, Kozo teaches in the coil wire rod (11, 10a,10b,) located at a connection portion between the tooth body (23a) and the flange portion (23c) of a plurality of the coil wire rods included in the coils (11) , at least one corner (at least corner of 10a, 10b) facing an outer periphery side with respect to the axis of outside surfaces of the plurality of stranded wires (11, 10a,10b, wire strand) forms an arc shape (10a,10b are convex and concave portions, is arced) when viewed from the direction of the axis (see fig.5a). Therefore, it would have been obvious to one with ordinary skill in the art before the effective filling date of the invention to modify the electrical motor of Trimmel wherein in the coil wire rod located at a connection portion between the tooth body and the flange portion of the plurality of the coil wire rods included in the coils, at least one corner facing an outer periphery side with respect to the axis of outside surfaces of the plurality of stranded wires forms an arc shape when viewed from the direction of the axis as suggested by Kozo to provide an improved motor device with aligned winding with high accuracy as suggested in( Kozo, Page-8, P[13,14]).

Trimmel fails to explicitly teach wherein in the coil wire rod located at a connection portion between the tooth body and the flange portion of the plurality of the coil wire rods included in the coils, at least one corner facing an outer periphery side with respect to the axis of outside surfaces of the plurality of stranded wires forms a flat shape expanding in a direction orthogonal to a radial direction with respect to the axis when viewed from the direction of the axis. However, Kozo teaches in the coil wire rod (11, 10a,10b,) located at a connection portion between the tooth body (23a) and the flange portion (23c) of a plurality of the coil wire rods included in the coils (11) , at least one corner (at least corner of 10a, 10b) facing an outer periphery side with respect to the axis of outside surfaces of the plurality of stranded wires (11, 10a,10b, wire strand) forms a flat shape (10a,10b are convex and concave portions with flat portions) expanding in a direction orthogonal to a radial direction with respect to the axis when viewed from the direction of the axis (see fig.5a). Therefore, it would have been obvious to one with ordinary skill in the art before the effective filling date of the invention to modify the electrical motor of Trimmel wherein in the coil wire rod located at a connection portion between the tooth body and the flange portion of the plurality of the coil wire rods included in the coils, at least one corner facing an outer periphery side with respect to the axis of outside surfaces of the plurality of stranded wires forms a flat shape expanding in a direction orthogonal to a radial direction with respect to the axis when viewed from the direction of the axis as suggested by Kozo to provide an improved motor device with aligned winding with high accuracy as suggested in( Kozo, Page-8, P[13,14]).

Re-claim 18, Trimmel as modified discloses the electric motor of claim 9. Trimmel fails to explicitly teach comprising: a rotor extending along a center axis; and the stator according to claim 9 covering the rotor from an outer periphery side. However, Kozo teaches a rotor (22) extending along a center axis; and the stator (23) according to claim 9 covering the rotor from an outer periphery side (rotor 22 is inside of 23, see fig.4). Therefore, it would have been obvious to one with ordinary skill in the art before the effective filling date of the invention to modify the electrical motor of Trimmel wherein : a rotor extending along a center axis; and the stator according to claim 9 covering the rotor from an outer periphery side as suggested by Kozo to provide an improved motor device with aligned winding with high accuracy as suggested in( Kozo, Page-8, P[13,14]). Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure in PTO892. 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.
