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 .
Priority
Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55.
Specification
The title of the invention is not descriptive. A new title is required that is clearly indicative of the invention to which the claims are directed.
The following title is suggested: STATOR COIL WITH BENT PORTION.
Claim Objections
Claims 1-9 are objected to because of the following informalities: All instances of the phrase “assumed to be” should be deleted from the claims. Appropriate correction is required.
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.
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.

the first connecting portion 54A includes a first circumferential region 55A that is a region on the circumferential first side, a second circumferential region 55A that is a region on the circumferential second side of the first circumferential region, and a connecting region 54A that is a region connecting the first circumferential region 55A and the second circumferential region 55A and includes a radially bent portion formed to be bent in the radial direction (the wire 50A is bent in the radial direction at 54A FIG. 4),
the first circumferential region 55A includes a first section that is on the axial second side of the third-phase coil 41W connecting portion and overlaps the third-phase coil 41W connecting portion in the axial view, and a second section that is on the axial first side of the second-phase coil 41V connecting portion and overlaps the second-phase coil 41V connecting portion in the axial view (adjacent wires overlap each other FIG. 8),
the second circumferential region 55A includes a third section that is on the axial first side of the third-phase coil 41W connecting portion and overlaps the third-phase coil 41W connecting portion in the axial view, and a fourth section that is on the axial second side of the second-phase coil 41V connecting portion and overlaps the second-phase coil 41V connecting portion in the axial view (adjacent wires overlap each other FIG. 8),
the first circumferential region 55A is inclined as a whole to the axial first side toward the circumferential second side, and the second circumferential region 55A is inclined as a whole to the axial second side toward the circumferential second side, and (FIG. 4):
