Office Action

§103
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 . Election/Restrictions Claims 28, 30-31, 33, and 37-46 are withdrawn from further consideration pursuant to 37 CFR 1.142(b), as being drawn to a nonelected species, there being no allowable generic or linking claim. Applicant timely traversed the restriction (election) requirement in the reply filed on 2/12/2026. Applicant's election with traverse of claims 1-27, 29, 32, and 34-36 in the reply filed on 2/12/2026 is acknowledged. The traversal is on the grounds that the claimed subject matter of the groups are sufficiently related such that an undue burden would not be present. This is not found persuasive because the two groups are classified in different areas. The requirement is still deemed proper and is therefore made FINAL. Drawings The drawings are objected to as failing to comply with 37 CFR 1.84(p)(5) because they do not include the following reference sign mentioned in the description: 201 as seen in paragraph [0393]. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Claim Objections Claims 1 and 3 are objected to because of the following informalities: In claim 1 lines 15-16 the phrase “positioned radially outer side” should instead be “positioned on a radially outer side.” In claim 3 line 3 the phrase “a radially outer side” should instead be “on a radially outer side.” Appropriate correction is required. 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. Claims 1-2, 6-14, and 18 are rejected under 35 U.S.C. 103 as being unpatentable over U.S. Patent Application Publication No. 2014/0167546 to Sutani et al. (hereinafter Sutani; cited by Applicant on 6/12/2023) in view of U.S. Patent Application Publication No. 2011/0012458 to Atallah et al. (hereinafter Atallah). Regarding claim 1, Sutani teaches a power transmission device (Paragraph [0090]) comprising: a drive-side magnet (FIG. 11, 52) that includes a plurality of poles and rotates (Paragraph [0090]); a magnet (FIG. 11, 62) that has a number of poles larger than a number of poles of the drive-side magnet (Paragraph [0092]-[0093]); a pole piece (FIG. 11, 46) that includes a plurality of magnetic body portions (Paragraph [0094]); and a sealing member (FIG. 11, 44) that partitions a space into a driving side (FIG. 11, 5) where the drive-side magnet is disposed and a driven side space (FIG. 11, 6) where the magnet and the pole piece are disposed, the sealing member sealing fluid between the driving side space and the driven side space (Paragraph [0090]), wherein the pole piece and the magnet have a cylindrical shape (Paragraph [0090]-[0093]) and are disposed coaxially with and radially outside of the drive-side magnet (Paragraph [0090]-[0093]), and the sealing member including a sealing cylinder portion (FIG. 11, 44; Paragraph [0090]) positioned radially outside of the drive-side magnet, and a sealing bottom surface portion (FIG. 11, 45) covering the sealing cylinder portion from the driving side space. Sutani does not teach a housing that houses the drive-side magnet; a stationary magnet that is fixed to the housing; and a pole piece that rotates by modulating a magnetic flux between the drive-side magnet and the stationary magnet.

Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the power transmission device of Sutani with the teachings of Atallah by having a stationary magnet and a moving pole piece as it may provide advantageous rotational properties such as reduced fluid turbulence (Paragraph [0028]). Regarding claim 2, Sutani in view of Atallah teaches the power transmission device according to claim 1, wherein a number Npp of the magnetic body portions has a relationship of: Npp = (Pin + Pf)/2 with the number of poles Pin of the drive-side magnet and the number of poles Pf of the stationary magnet (Paragraph [0061]). Regarding claim 6, Sutani in view of Atallah teaches the power transmission device according to claim 1. Sutani does not teach a bearing member that rotatably supports the pole piece with respect to the housing, wherein the pole piece is positioned away from the bearing member with respect to an imaginary line connecting an end portion of the drive-side magnet away from the bearing member and an end portion of the stationary magnet away from the bearing member, in an axial direction of the drive-side magnet. However, Atallah teaches a bearing member (FIG. 4, 419) that rotatably supports the pole piece with respect to the housing, wherein the pole piece is positioned away from the bearing member with respect to an imaginary line connecting an end portion of the drive-side magnet away from the bearing member and an end portion of the stationary magnet away from the bearing member, in an axial direction of the drive-side magnet (FIG> 4; 406, 410, 414). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the power transmission device of Sutani with the teachings of Atallah to implement a bearing supporting the pole piece to help further radially position the pole piece. Regarding claim 7, Sutani in view of Atallah teaches the power transmission device according to claim 1.

Sutani in view of Atallah and Kusakari does not teach a number of poles of the motor unit differing from the number of poles of the drive-side magnet. However, Miyamoto teaches a number of poles of the motor unit (FIG. 2, 33) being different from the number of poles of the drive-side magnet (FIG. 2, 31). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the power transmission device according to Sutani in view of Atallah and Kusakari with the teaches of Miyamoto to differentiate the pole numbers of the motor unit and drive-side magnet to result in a desired rotational profile of the device.

However, Liu teaches a DC motor (FIG. 2, 23) including a commutator and a brush (Paragraph [0005]), and a lock determination unit (Paragraph [0046]-[0066]). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the power transmission device of Sutani in view of Atallah and Kusakari with the teachings of Liu to provide a lock determined DC motor as a DC motor has certain application specific benefits such as simplicity in construction. Claims 29, 32, and 34-36 are rejected under 35 U.S.C. 103 as being unpatentable over Sutani in view of Atallah and in further view of Miyamoto. Regarding claim 29, Sutani in view of Atallah teaches the power transmission device according to claim 1, wherein Sutani further teaches a motor unit (FIG. 11, 7) driving a drive-side magnet (FIG. 11, 52).

Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the power transmission device of Sutani in view of Atallah with the teachings of Miyamoto by placing the motor inside the drive-side magnet in order to reduce the axial footprint of the device. Regarding claim 35, Sutani in view of Atallah and Miyamoto teaches the power transmission device according to claim 34, wherein Miyamoto further teaches an interposition member (FIG. 2, 25) magnet of a magnetic body and disposed between the rotor and the drive-side magnet (FIG. 2, 31). Regarding claim 36, Sutani in view of Atallah teaches the power transmission device according to claim 1, wherein the drive-side magnet has a cylindrical shape (Paragraph [0092]). Sutani in view of Atallah does not teach a stator that includes a coil, wherein the stator is disposed inside the drive-side magnet and rotates the drive-side magnet as a rotor. However, Miyamoto teaches a stator (FIG. 2, 30) that includes a coil (FIG. 2, 33), wherein the stator is disposed inside the drive-side magnet (FIG. 2, 28) and rotates the drive-side magnet as a rotor. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the power transmission device of Sutani in view of Atallah with the teachings of Miyamoto by placing the stator inside the drive-side magnet in order to reduce the axial footprint of the device.
