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 .
Claim Objections
Claims 2 and 5 objected to because of the following informalities:
Claims 2 and 5 recite “through-openings” for “radial lugs,” while also reciting “through-openings” for “motor carrier.” Examiner suggests differentiating between the two “through-openings” to prevent confusion.
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.

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 (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 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 2-7 are rejected under 35 U.S.C. 103 as being unpatentable over Devermann et al. (US 2020/0195079 A1) in view of Bitzer (US 8,400,031 B2).
Regarding claim 2/1, Devermann was discussed above in claim 1. Devermann further discloses said stator main body (18, 20),
Devermann does not disclose on said annular main body part, has radial lugs aligned with said through-openings of said motor carrier, which said radial lugs each have a through-opening formed therein for an associated one of said axially oriented contact pins.
Bitzer discloses on said annular main body part (3), has radial lugs (see annotation below) aligned with said through-openings (30) of said motor carrier (15), which said radial lugs each have a through-opening (see annotation below) formed therein for an associated one of said axially oriented contact pins (8).

It would have been obvious to one of ordinary skill in the art before the effective filing of the claimed invention to have modified Devermann in view of Bitzer to disclose on said annular main body part, has radial lugs aligned with said through-openings of said motor carrier, which said radial lugs each have a through-opening formed therein for an associated one of said axially oriented contact pins, for the advantages of a reliable sealing and inexpensive manufacturing (col. 1 ll. 45-46).
Regarding claim 3/2, Devermann in view of Bitzer was discussed above in claim 2. Devermann further discloses said stator main body (18, 20) is formed as a laminated core (12; ¶ [0044]) from a first number of stacked laminations.
Devermann does not disclose said radial lugs are formed by a second number of said laminations, wherein said second number is smaller than a total number of said laminations of said stator main body.
Bitzer discloses said radial lugs (see annotation below) are formed by a second number of said laminations (FIG. 2), wherein said second number is smaller than a total number of said laminations of said stator main body (3; FIG. 1; Bitzer discloses “the stator 3 has a conventional design with sheet metal stacks.).
It would have been obvious to one of ordinary skill in the art before the effective filing of the claimed invention to have modified Devermann in view of Bitzer to disclose said radial lugs are formed by a second number of said laminations, wherein said second number is smaller than a total number of said laminations of said stator main body, for the advantages of a reliable sealing and inexpensive manufacturing (col. 1 ll. 45-46).
Regarding claim 4/2, Devermann in view of Bitzer was discussed above in claim 2. Devermann further discloses said coil or winding insulation (50, 66) has a number of axially raised insulating pins (69; FIG. 4, centering element 66 is directly attached to the insulation 50) corresponding to a number of said axially oriented contact pins (45), said axially raised insulating pins (69) protrude into said receiving or mounting space formed by said annular main body part (18) of said stator main body (18, 20; FIG. 4, 6) and through which a respective one of said axially oriented contact pins (45) passes (FIG. 6).
Regarding claim 5/4, Devermann was discussed above in claim 4. Devermann does not disclose said axially raised insulating pins of said coil or winding insulation are assigned to said radial lugs of said stator main body and sit in said through-openings of said radial lugs.
Bitzer discloses said axially raised insulating pins (27) are assigned to said radial lugs (see annotation above) of said stator main body (3) and sit in said through-openings (see annotation above) of said radial lugs (FIG. 2).
Devermann would be modified such that the centering means 69 also comprises the raised insulating pins 27 of Bitzer protruding axially upward towards the stator, so that the coil or winding insulation would include axially raised insulating pins.
It would have been obvious to one of ordinary skill in the art before the effective filing of the claimed invention to have modified said axially raised insulating pins of said coil or winding insulation are assigned to said radial lugs of said stator main body and sit in said through-openings of said radial lugs, for the advantages of a reliable sealing and inexpensive manufacturing (col. 1 ll. 45-46).
Regarding claim 6/4, Devermann was discussed above in claim 4. Devermann further discloses said coil or winding insulation (50, 66) has radially inwardly directed lugs (70, 71); and
said axially raised insulating pins (69) are molded onto said radially inwardly directed lugs (70, 71) of said coil or winding insulation (50, 66).
Regarding claim 7/6, Devermann was discussed above in claim 6. Devermann further discloses said radially inwardly directed lugs (70, 71) of said coil or winding insulation (50, 66) lie against said radial lugs (as modified by Bitzer) disposed on said annular main body part (18) of said stator main body (18, 20) and against associated said sealing elements (72) directly or via molded-on hollow-cylindrical molded parts (FIG. 6).
Claim 13 is rejected under 35 U.S.C. 103 as being unpatentable over Best et al. (US 8,415,846 B2) in view of Shi et al. (US 2024/0079923 A1).
Regarding claim 13/10, Best was discussed above in claim 10. Best further discloses said connection contacts are busbar-shaped connection contacts (FIG. 2).
Best does not disclose said axially oriented contact pins are welded with said connection contacts.
Shi discloses said axially oriented contact pins (222) are welded with said connection contacts (122; ¶ [0133]).
It would have been obvious to one of ordinary skill in the art before the effective filing of the claimed invention to have modified Best in view of Shi to disclose said axially oriented contact pins are welded with said connection contacts, as welding is well known as an electrical connection method with advantages of increased structural integrity (¶ [0012]).
