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 .
Continued Examination Under 37 CFR 1.114
A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 11/18/2025 has been entered.
Response to Arguments
Applicant’s arguments, see page 10, filed 11/18/2025, with respect to the rejection(s) of claim(s) 1 under 35 U.S.C. § 112(a) have been fully considered and are persuasive. Therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made in view of the claim amendment below.
Claim Rejections - 35 USC § 102
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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.

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, 8 and 15 are rejected under 35 U.S.C. 103 as being unpatentable over Yoshikawa et al. (JP 2010-110048 A) in view of Natsume et al. (JP 2006-254569 A).
Regarding claim 2/1, Yoshikawa was discussed above in claim 1. Yoshikawa discloses wherein the base portion (44) is provided such that a gap corresponding to an axial-direction thickness of the opened-ring portion (53) is formed between the base portion (44) and the magnetic-pole piece (10) in the axial direction, and in the snap-fit connected state, the opened-ring portion (53) is held in the gap so that axial-direction displacement is restricted (FIG 2).

Yoshikawa does not disclose the opened-ring portion is at the axial end of the insulator, such that the base portion is in the gap.
Natsume discloses the opened-ring portion (21g) is at the axial end of the insulator (4), such that the base portion (22g) is in the gap (FIG 5, 7).
It would have been obvious to one of ordinary skill in the art before the effective filing of the claimed invention to have modified Yoshikawa in view of Natsume to disclose the opened-ring portion is at the axial end of the insulator, such that the base portion is in the gap, as the swapping the location of the base portion and the opened-ring portion is obvious to try from a finite number of solutions.
Regarding claim 8/7, Yoshikawa was discussed above in claim 7. Yoshikawa further discloses with a total of four magnetic-pole pieces (10) including first and second magnetic-pole pieces (10a, 10b) snap-fit connected as a set of two adjacent magnetic-pole pieces and third and fourth magnetic-pole pieces (10a, 10b) snap-fit connected as a set of two adjacent magnetic-pole pieces (FIG 9),

Yoshikawa does not disclose wherein in the wiring step,
an apparatus is applied, the apparatus including a rotational-positioning mechanism having a rotation axis in a stacking direction of the magnetic-pole piece, and a conductive-wire feeding and winding flyer which feeds the conductive wire while turning about a rotation axis set in a direction perpendicular to the rotation axis of the rotational-positioning mechanism, and
the magnetic-pole pieces are attached to the rotational-positioning mechanism, such that the magnetic-pole pieces are arranged with the tooth portions distant from each other in the circumferential direction so as to have a V shape,
thereafter, the wiring step includes
a winding step 1 of winding the conductive wire around the tooth portion of the first magnetic-pole piece by the flyer,
a jumper wire step 1 of rotating the rotational-positioning mechanism so that the second magnetic-pole piece is opposed to the flyer, and arranging the jumper wire, without cutting the conductive wire,
