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 . Claims 1-20 are presented for examination.
Information Disclosure Statement
The information disclosure statement (IDS) submitted on 12/09/2025 and 12/20/2024 are in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner.
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 1-20 are rejected under 35 U.S.C. 103 as being unpatentable over Wang (CN 208571728 hereinafter “Wang”) in view of Makino (US PG Pub 20180309333 hereinafter “Makino”).
Re-claim 1, Wang discloses a motor (Title), comprising: a stator (10) and a rotor
(20); wherein the stator (10) comprises a stator core segment (102,104), multiple stator teeth (1022) extending axially are provided on an inner circumferential surface (surface of 1022) of the stator core segment (102, 104), a stator slot (between 1022) is formed between two adjacent stator teeth (1022), and an auxiliary slot (1026) is provided on a top end of at least part of the stator teeth (see fig.1-4).
Wang fails to explicitly teach that the motor is a permanent magnet motor.
However, Makino teaches the motor is a permanent magnet motor (P[0031], IPM).
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 motor of Wang wherein the motor is a Permanent Magnet motor as suggested by Makino which is used as interior motor, using rotating magnet in rotor for speed or rotation of device using magnets for magnetic field generation (Makino, P[0030-0031]).

Re-claim 2, Wang as modified discloses the permanent magnet motor according to claim 1 above.
Wang fails to explicitly teach wherein the rotor comprises multiple rotor core segments staggered by a first preset angle, there are multiple stator core segments, and the stator core segments and the rotor core segments are arranged correspondingly.
However, Makino teaches wherein the rotor comprises multiple rotor core segments (annotated fig.2) staggered by a first preset angle (0s), there are multiple stator core segments (annotated fig.2), and the stator core segments (annotated fig.2) and the rotor core segments (annotated fig.2) are arranged correspondingly.
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 motor of Wang wherein the rotor comprises multiple rotor core segments staggered by a first preset angle, there are multiple stator core segments, and the stator core segments and the rotor core segments are arranged correspondingly as suggested by Makino which is used as interior motor, using rotating magnet in rotor for speed or rotation of device using magnets for magnetic field generation (Makino, P[0030-0031]).
Re-claim 3, Wang as modified discloses the permanent magnet motor according to claim 2, wherein positions and/or quantities of the auxiliary slots on the stator core segments (1026) corresponding to different rotor core segments (rotor is made of multiple rotor iron cores pressed together as shape din fig.8) are different (only have 6 of 1026, but different number of rotor core).
Re-claim 4, Wang as modified discloses the permanent magnet motor according to claim 2, wherein shapes, positions and quantity of the auxiliary slots on the stator core segments are consistent (see fig.1, 1026 are 6), and the stator core segments are staggered by a second preset angle (segments are staggered where one has 1026 at top, the second one is staggered with no 1026, see fig.1).
Re-claim 5, Wang as modified discloses the permanent magnet motor according to claim 1, wherein the auxiliary slots (1026) on the stator core segment are arranged periodically (2-1-2-1-2-1, see fig.1).
Re-claim 6, Wang as modified discloses the permanent magnet motor according to claim 5, wherein one or more adjacent stator teeth (at least one, see annotated fig.1) not provided with the auxiliary slot at the top end (annotate fig.1) are defined as a group, one or more adjacent stator teeth provided with the auxiliary slot at the top end (annotate fig.1) are defined as a group, and the group of stator teeth not provided with the auxiliary slot at the top end and the group of stator teeth provided with the auxiliary slot at the top end (annotate fig.1) are alternately arranged (annotate fig.1).
Re-claim 7, Wang discloses the permanent magnet motor according to claims 1, wherein the auxiliary slots (1026) axially run (they go from top to bottom) through the stator core segment (see fig.1).
Re-claim 8, Wang as modified discloses the permanent magnet motor according to claims 1, wherein a radial cross-section (W2) of the auxiliary slot (1026) has an axially symmetric shape (shape of W2), and the auxiliary slot (1026) is provided at a middle position (mid position of tooth in fig.3) of the top end of the stator tooth (annotated fig.3), so that a symmetry axis of the axially symmetric shape coincides with a symmetry axis of the stator tooth (annotated fig.3).
Re-claim 9, Wang as modified discloses the permanent magnet motor according to claim 8, wherein the radial cross-section of the auxiliary slot is arc-shaped (annotated fig.3, shape of 1026 is arc or U shape), U-shaped or V-shaped.
