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, 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.
Claims 1-2, 4, 6-8, 14, 16-18 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Kim et al. (WO2021002603, “Kim”) in view of Yoshimura (US20080297010, “Yoshimura”) and Bilteryst et al. (US20170070110, “Bilteryst”).

Hong discloses the end of the screw shaft 5410 is press-fitted into the hollow portion of the hollow shaft 5700 (fig 12, [0154]).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to configure the end of the screw shaft of Kim in view of Yoshimura and Bilteryst to be press-fitted into the hollow portion of the hollow shaft, as disclosed by Hong, in order to fix the end of the screw shaft to the hollow shaft for co-rotation, as taught by Hong ([0154]).

Claim 13 is rejected under 35 U.S.C. 103 as being unpatentable over Kim in view of Yoshimura and Bilteryst and in further view of Lautenschlager et al. (US20160046448, “Lautenschlager”).
Re claim 13, Kim in view of Yoshimura and Bilteryst disclose claim 1 as discussed above but are silent with respect to at least one keyway is provided in the one end portion of the hollow shaft.
Lautenschlager discloses at least one keyway 13 is provided in the one end portion of the hollow shaft 2 (figs 1-2, [0069]).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to configure the one end portion of the hollow shaft of Kim in view of Yoshimura and Bilteryst with at least one keyway is provided in the one end portion of the hollow shaft, as disclosed by Lautenschlager, in order to positionally fix the hollow shaft and the screw shaft, as demonstrated by Lautenschlager (screw shaft will always be at a specific circumferential position with respect to the hollow shaft).
Claim 15 is rejected under 35 U.S.C. 103 as being unpatentable over Kim in view of Yoshimura and Bilteryst and in further view of Tatsumi et al. (US4377762, “Tatsumi”).
Re claim 15, Kim in view of Yoshimura and Bilteryst discloses claim 1 as discussed above but is silent with respect to the hollow shaft is made of a material whose hardness is lower than that of the bearing.
Tatsumi discloses the shaft is made of a material whose hardness is lower than that of the material of the structure it is inserted in order to be snugly fitted to that structure (fig 2, col 1, ln 57 to col 2, ln 2).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to at least try configuring the hollow shaft of Kim in view of Yoshimura and Bilteryst to be made of a material whose hardness is lower than that of the bearing, as disclosed by Tatsumi for a shaft and structure it is inserted, in order to provide a snug fit between the hollow shaft and bearings, as taught by Tatsumi.
Response to Arguments
Applicant's arguments filed 6/5/26 have been fully considered but they are not persuasive.
Applicant argues that Bilteryst does not disclose the alignment part and the small diameter portion are configured such that axial alignment of the screw shaft with the hollow shaft is achieved prior to engagement of the coupling part with the large diameter portion (pg 8, last para to pg 9, 3rd para). Examiner disagrees.
Bilteryst specifically states “when the shaft is fitted, these arrangements make it possible to make the knurled parts of the shaft enter the material of the magnet wheels, after having centered the wheels by means of the smooth part of the shaft” ([0036]) showing the shaft is centered by the smooth or alignment part 115 before the knurled or coupling part 135 engages with the large diameter portion 225. In other words Bilteryst is teaching that the alignment part 115 provides centering with respect to the shaft and the magnet wheels before the knurled part is engaged.
Although Bilteryst is for a shaft and magnet wheel one in the art would recognize the teaching of Bilteryst will have the same affect for a shaft and a hollow shaft-centering before press-fitting knurled part.
Allowable Subject Matter
Claim 11 is objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Note: reasons for allowing claim 11 in OA mailed 3/13/26.
Conclusion
Maekawa (JP2004336965) discloses a shaft with a small diameter portion and a knurled portion with a large diameter inserted into rotor hole having a small diameter portion and large diameter portion (figs 1& 3-6, [0021-0022]).
