Claim Objections
Claim 11 is objected to because of the following informalities: For claim 11, the recitations of “the plurality of venting channels” and “the plurality of venting holes” (see last two lines of claim 11) should be changed to “the at least one venting channel” and “the at least one venting hole”, respectively, for comprehension of the claim. 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.
Claim(s) 1-5, 8-11, 14, and 15 is/are rejected under 35 U.S.C. 103 as being unpatentable over Krais et al. (US Patent No.: 11152827) in view of Japanese Patent Document No.: JP 56020349 U, hereinafter "JP 349U".
For claim 1, Krais et al. disclose the claimed invention comprising: at least one venting groove (reference numeral 80, see figures 7, 8), at least one venting opening (reference numeral 79, see figures 7, 8), and a front surface (i.e. surface of plate 41 facing towards rotor 2, see figure 7) and a rear surface (i.e. surface of plate 41 facing away from rotor 2, see figure 7) each having an outer circumference corresponding to an outer circumference of a rotor body (reference numeral 2) of the rotor assembly (see figures 7, 8), the venting groove (reference numeral 80) extending from an interior to the outer circumference of the front surface (i.e. groove 80 extending from an inner radial position to the outer circumference of plate 41, see figure 7), and the venting groove (reference numeral 80) and the venting opening (reference numeral 79) being in fluid communication with ambient air (see figures 7, 8). Krais et al. however do not specifically disclose the venting opening extending from the front surface to the rear surface.
JP 349U disclose a venting opening (reference numeral 8) extending from the front surface to the rear surface (see figures 1, 4, 5).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have the venting opening extend from the front surface to the rear surface as disclosed by JP 349U for the venting opening of Krais et al. for predictably providing desirable configuration for facilitating the ventilation of the device.
For claim 2, Krais et al. disclose an inner end of the venting groove (reference numeral 80, figures 7, 8), being arranged at the interior of the second ring-shaped end member (i.e. a radially inner end portion of groove 80, see figures 7, 8), comprising a venting aperture (i.e. hole 79 can be considered a venting aperture, see figures 7, 8). Krais et al. in view of JP 349U however do not specifically disclose the venting aperture extending from the front surface to the rear surface. JP 349U further discloses the venting aperture (i.e. hole 8 can be considered the venting aperture) extending from the front surface to the rear surface (i.e. aperture 8 extending axially through the end member 2, see figure 4), and it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have the venting aperture extend from the front surface to the rear surface as disclosed by JP 349U for the venting aperture of Krais et al. in view of JP 349U for predictably providing desirable configuration for facilitating the ventilation of the device.
For claim 3, Krais et al. disclose a plurality of venting grooves (reference numeral 80, see figures 7-9), a plurality of venting apertures and a plurality of venting openings (i.e. hole 79 considered the venting apertures and venting openings, see figures 7, 8), the venting grooves (reference numeral 80), venting apertures and venting openings (i.e. hole 79 considered the venting apertures and venting openings, see figures 7, 8) being arranged in a circumferential direction of the ring-shaped end member (see figure 9).
