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 1,2,6,7,9,14 are rejected under 35 U.S.C. 103 as being unpatentable over Holmqvist (US PG PUB 20240039348 hereinafter “Holmqvist”) in view of Kouda (US Patent 12653473 hereinafter “Kouda”).
Re-claim 1, Holmqvist discloses a motor (100) comprising: a rotor (102) rotatable about a central axis (axis of shaft 104) extending in an axial direction (113); a stator (134, with 110) including a stator core (134) of a magnetic body () in which a electromagnets portion (110) is located; a bracket (210, housing holds stator) including a stator holder (108) in a tubular shape (108 is tubular) extending in the axial direction and surrounding the central axis (surrounding 113), the stator holder (108) holding the stator core (110,134); and a heat dissipation portion (128) extending in one axial direction from the coil [electromagnet portion] portion (110), being separate from the bracket (separate from housing 210), and held by the stator holder (108); wherein the heat dissipation portion (108)includes: an annular portion (128 is annular, around 108, see fig.1) that has an annular shape surrounding the stator holder (108) and is located on a radially outer surface of the stator holder (see fig.1);
Holmqvist fails to explicitly show the magnetic body in which a coil portion is located, the annular portion is that has an annular shape; and an extension extending radially outward from the annular portion.
However, Kouda teaches the magnetic body in which a coil portion (70) is located, the annular portion is that has an annular shape (412a is annular, see fig.10); and an extension (43,44) extending radially outward (see fig.2) from the annular portion (from 412a).
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 device of Holmqvist wherein the magnetic body in which a coil portion is located, the annular portion is that has an annular shape; and an extension extending radially outward from the annular portion as suggested by Kouda to provide cooling for heating electromagnetics and provide more efficient device (Kouda, P[0091]).

Re-claim 2, Holmqvist as modified discloses the motor according to claim 1.
However, Holmqvist fails to explicitly teachoH wherein the extension includes a plurality of extensions arranged side by side in the circumferential direction.
However, Kouda teaches wherein the extension (44) includes a plurality of extensions (442) arranged side by side (see fig.2, 44 next to each other circumferentially) in the circumferential direction (around shaft, or around axis ax).
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 device of Holmqvist wherein the extension includes a plurality of extensions arranged side by side in the circumferential direction as suggested by Kouda to provide cooling for heating electromagnetics and provide more efficient device (Kouda, P[0091]).
Re-claim 6, Holmqvist as modified discloses the motor according to claim 1.
Holmqvist fails to explicitly teach wherein a material of at least the annular portion of the heat dissipation portion is aluminum or an aluminum alloy.
However, Kouda teaches teach wherein a material of at least the annular portion of the heat dissipation portion is aluminum or an aluminum alloy (P[0140],40 includes 44 which are made of aluminum, and all of stator base see P[0081], heat dissipation member made of aluminum).
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 device of Holmqvist wherein a material of at least the annular portion of the heat dissipation portion is as suggested by Kouda to provide better heat dissipation and cooling for heating electromagnetics and provide more efficient device having good thermal conductivity stator (Kouda, P[0091,0081,0107]).
Re-claim 7, Holmqvist as modified discloses the motor according to claim 1.
Holmqvist fails to explicitly teach the extension includes: a distal end portion expanding in a direction perpendicular to a radial direction at a radially outer end portion of the extension; and a connector that extends in the radial direction and connects the distal end portion to the annular portion.
However, Kouda teaches teach the extension (44) includes: a distal end portion (442) expanding in a direction perpendicular to a radial direction at a radially outer end portion of the extension (44); and a connector (43) that extends in the radial direction and connects the distal end portion4342) to the annular portion (see fig.2 from Kouda).
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 device of Holmqvist wherein the extension includes: a distal end portion expanding in a direction perpendicular to a radial direction at a radially outer end portion of the extension; and a connector that extends in the radial direction and connects the distal end portion to the annular portion as suggested by Kouda to provide better heat dissipation and cooling for heating electromagnetics and provide more efficient device having good thermal conductivity stator (Kouda, P[0091,0081,0107]).
Re-claim 9, Holmqvist as modified discloses the motor according to claim 1.
Holmqvist fails to explicitly teach wherein the extension has a minimum axial width larger than a width of the extension in a direction perpendicular to the axial direction and the radial direction.
However, Kouda teaches wherein the extension has a minimum axial width (annotated fig.2) larger than a width of the extension (annotated fig.2) in a direction perpendicular to the axial direction and the radial direction (annotated fig.2).
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 device of Holmqvist wherein the extension has a minimum axial width larger than a width of the extension in a direction perpendicular to the axial direction and the radial direction as suggested by Kouda to provide better heat dissipation and cooling for heating electromagnetics and provide more efficient device having good thermal conductivity stator (Kouda, P[0091,0081,0107]).
Re-claim 14, Holmqvist as modified discloses the motor according to claim 1, wherein the rotor includes a magnet (111) opposing the stator (108) in the radial direction; and the stator is located radially inward of the magnet (111).
