Office Action

§103
DETAILED ACTION The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . This Office Action is responsive to the Applicant's communication filed 07 January 2026. In view of this communication and the amendment concurrently filed: claims 1-14 were previously pending; claims 15-20 were added by the amendment; and thus, claims 1-20 are now pending in the application. Response to Arguments The Applicant’s arguments, filed 07 January 2026, have been fully considered and are persuasive. The Applicant’s argument (pages 1-2 of the Remarks) allege that the Yoneda reference does not disclose the newly added limitation of the independent claims, which recites that “no fan blade is provided” (or equivalent) on the outer radial surface of the rotor portion. Since Yoneda does disclose such fan blades (i.e. element 5 in figure 1), this argument is persuasive. However, the Iwai reference, previously cited, discloses alternative arrangements of fan blades, with blades provided either on the outer radial surface of the rotor portion or separately from the rotor portion. Thus, Yoneda in view of Iwai renders obvious the new limitations, and new grounds of rejection have been made in view of this combination. Priority Receipt is acknowledged of papers submitted under 35 U.S.C. 119(a)-(d) or (f), 365(a) or (b), or 386(a), which papers have been placed of record in the file. Disclosure The specification has not been checked to the extent necessary to determine the presence of all possible minor errors. Applicant's cooperation is requested in correcting any errors of which applicant may become aware in the specification. 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. 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. Claim(s) 1-2, 4, 7-9, 11, 14-16, and 18 is/are rejected under 35 U.S.C. 103 as being unpatentable over Yoneda et al. (US 2014/0127049 A1), hereinafter referred to as “Yoneda”, in view of Iwai (US 2015/0295471 A1), hereinafter referred to as “Iwai”. Regarding claim 1, Yoneda discloses an outer rotor type motor covered with a cover member [82] (fig. 1-2; ¶ 0021-0023), the motor comprising: a motor substrate [11] (fig. 1; ¶ 0025); a stator portion [3] provided on the motor substrate [11] (fig. 1; ¶ 0021, 0025); a rotor portion [2] mounted with a rotational shaft [23] and configured to rotate about the stator portion [3] (fig. 1; ¶ 0021); and a cover member [82] provided on an outside of the rotor portion [2] with respect to a radial direction of the rotor portion [2] and an axial direction of the rotational shaft [23] and arranged to be fixed (fig. 1; ¶ 0023), PNG media_image1.png 439 701 media_image1.png Greyscale wherein a first opening portion [9] is formed on a central portion, in the radial direction, of a first portion of the cover member [82] opposing a part on which the rotational shaft [23] of the rotor portion [2] is mounted in the axial direction (fig. 1; ¶ 0023), wherein the rotor portion [2] includes a cylindrical outer surface [21b] coaxial with the rotational shaft [23] (fig. 1; ¶ 0021), and wherein an air is sucked inside of the cover member [82] from an outside of the cover member [82] through the first opening portion [9] by rotation of the rotor portion [2] (fig. 1; ¶ 0028), and the air sucked is discharged to the outside of the cover member [82] through a second opening portion [10] formed on a position away from the first opening portion [9] in the axial direction (fig. 1-2; ¶ 0028; the “intake port 9” is located at the top of the housing, while the “exhaust port 10” extends to the bottom of the housing). Yoneda does not disclose that no fan blade is provided at a radially outer side of the cylindrical outer surface [21b] of the rotor portion [2]. Iwai discloses an outer rotor type motor [104/105] comprising a stator portion [3] and a rotor portion [2] mounted with a rotational shaft [1] and configured to rotate about the stator portion [3] (fig. 18-19; ¶ 0153-0157, 0159-0162), wherein the rotor portion [2] includes a cylindrical outer surface [2b] coaxial with the rotational shaft [1] and no fan blade [60] is provided at a radially outer side of the cylindrical outer surface [2b] of the rotor portion [2] (fig. 18; ¶ 0154-0155). PNG media_image2.png 307 898 media_image2.png Greyscale It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to form the fan blades of Yoneda separately from the rotor as taught by Iwai, in order to more effectively block radiant heat (¶ 0157 of Iwai). Further, it has been held that making a component separable, in this case for the purpose of blocking radiant heat, instead of the integral structure disclosed in the prior art would have been a matter of obvious engineering choice. In re Dulberg, 289 F.2d 522, 523, 129 USPQ 348, 349 (CCPA 1961). Regarding claim 2, Yoneda, in view of Iwai, discloses a motor according to Claim 1, as stated above, wherein the second opening portion [10] is a gap space formed between the motor substrate [11] and the cover member [82] (fig. 1-2; ¶ 0023, 0028; the second opening portion is located axially above the substrate and axially below the cover member). Regarding claim 4, Yoneda, in view of Iwai, discloses a motor according to Claim 1, as stated above, wherein an end portion of the rotational shaft [23] on a side of the first opening portion [9] is positioned inside of the cover member [82] with respect to the axial direction (fig. 1; ¶ 0021). Regarding claim 7, Yoneda discloses an image forming apparatus for forming a toner image on a recording material (fig. 1-2; ¶ 0021-0023; neither the “image forming” language nor the recitation of its intended use imply any structure outside the motor structure recited in the body of the claim), the image forming apparatus comprising: a main body frame [81] (fig. 1; ¶ 0023); a motor substrate [11] (fig. 1; ¶ 0025); a stator portion [3] provided on the motor substrate [11] (fig. 1; ¶ 0021, 0025); a rotor portion [2] mounted with a rotational shaft [23] and configured to rotate about the stator portion [3] (fig. 1; ¶ 0021); and a cover member [82] provided on an outside of the rotor portion [2] with respect to a radial direction of the rotor portion [2] and an axial direction of the rotational shaft [23] and arranged to be fixed (fig. 1; ¶ 0023), wherein the motor substrate [11] is mounted on the main body frame [81] (fig. 1; ¶ 0023), PNG media_image3.png 448 692 media_image3.png Greyscale wherein a first opening portion [9] is formed on a central portion, in the radial direction, of a first portion of the cover member [82] opposing a part on which the rotational shaft [23] of the rotor portion [2] is mounted in the axial direction (fig. 1; ¶ 0023), wherein the rotor portion [2] includes a cylindrical outer surface [21b] coaxial with the rotational shaft [23] (fig. 1; ¶ 0021), and wherein an air is sucked inside of the cover member [82] from an outside of the cover member [82] through the first opening portion [9] by rotation of the rotor portion [2] (fig. 1; ¶ 0028), and the air sucked is discharged to the outside of the cover member [82] through a second opening portion [10] formed on a position away from the first opening portion [9] in the axial direction (fig. 1-2; ¶ 0028; the “intake port 9” is located at the top of the housing, while the “exhaust port 10” extends to the bottom of the housing).

The page is best reviewed promptly after applicant has received a final rejection or the claims have been twice rejected because some of the noted assistance must be requested within one month from the date of the latest rejection. See MPEP § 1204 for more information on filing a notice of appeal. If applicant should desire to appeal any rejection made by the examiner, a Notice of Appeal must be filed within the period for reply. The Notice of Appeal must be accompanied by the fee required by 37 CFR 41.20(b)(1). The current fee amount is available at: www.uspto.gov/Fees. If applicant should desire to file an after-final amendment, entry of the proposed amendment cannot be made as a matter of right unless it merely cancels claims or complies with a formal requirement made in a previous Office action. Amendments touching the merits of the application which otherwise might not be proper may be admitted upon a showing of good and sufficient reasons why they are necessary and why they were not presented earlier. A reply under 37 CFR 1.113 to a final rejection must include cancellation of or appeal from the rejection of, each rejected claim. The filing of an amendment after final rejection, whether or not it is entered, does not stop the running of the statutory period for reply to the final rejection unless the examiner holds all of the claims to be in condition for allowance. If applicant should desire to continue prosecution in a utility or plant application filed on or after May 29, 2000 and have the finality of this Office action withdrawn, an RCE under 37 CFR 1.114 may be filed within the period for reply. See MPEP § 706.07(h) for more information on the requirements for filing an RCE. The application will become abandoned unless a Notice of Appeal, an after final replay that places the application in condition for allowance, or an RCE has been filed properly within the period for reply, or any extension of this period obtained under either 37 CFR 1.136(a) or (b).
