Office Action

§112
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 . The examiner has been attempted to contact Mr. Jong Wan Suh in order to resolve the 112b issues in claims 6 and 7. Applicant, however, cannot be reached. Response to Arguments Applicant’s arguments with respect to claims 1-2, 4, 6-10, 12 and 15 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 6-7 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. As to claim 6, the recitation “the protrusion” at line 1 is in the singular while claim 1 recites “a pair of protrusions” at line 14. It is suggested that “the protrusion” at line 1 should be changed to "each protrusion" for clarity. As to claim 7, the recitation “the protrusion” at line 1 is in the singular while claim 1 recites “a pair of protrusions” at line 14. It is suggested that “the protrusion” at line 1 should be changed to "each protrusion" for clarity. Allowable Subject Matter Claims 1-2, 4, 8-10, 12 and 15 are allowed. The following is an examiner’s statement of reasons for allowance: As to claim 1, Li discloses a motor assembly comprising: a housing (Fig. 5); an impeller provided inside the housing (Fig. 5); a stator provided inside the housing and provided with a plurality of phase coils (Fig. 5); a rotor (Fig. 5) provided with a rotation shaft (10; Fig. 8) connected to the impeller and rotatably disposed with respect to the stator. PNG media_image1.png 594 693 media_image1.png Greyscale PNG media_image2.png 591 617 media_image2.png Greyscale Li fails to disclose a connection ring formed of an electrical conductor, and connected to one ends of the plurality of phase coils, wherein the connection ring comprises: a ring-shaped body with an opening at one side thereof; and a plurality of phase coil connection portions each extending in a radial direction from the body to be connected to ends of the plurality of phase coils, respectively. As to claim 1, Takada discloses a connection ring comprising an electrical conductor (Fig. 8), and connected to one ends of the plurality of phase coils, a bracket coupled to the housing to support the rotation shaft (Fig. 8), wherein the connection ring comprises: a ring-shaped body with an opening at one side thereof (Fig. 8); and a plurality of phase coil connection portions each extending in a radial direction from the body to be connected to ends of the plurality of phase coils (Fig. 8), respectively. PNG media_image3.png 660 514 media_image3.png Greyscale Li and Takada fail to discloses wherein the connection ring is provided with a pair of protrusions on respective circumferential sides thereof in an axial direction, respectively, wherein the bracket is provided with a pair of protrusion accommodation portions at respective circumferential sides thereof, such that the pair of protrusions are inserted and blocked from being separated from the bracket, wherein the pair of protrusion accommodation portions are each inclined with respect to an axial direction, to be spaced apart from each other toward the circumferential sides of the bracket, and wherein the protrusions are retained within the pair of protrusion accommodation portions, respectively, while being elastically deflected to be inclined with respect to the axial direction along the pair of protrusion accommodation portions. As to dependent claims 2, 4, 8-10, 12, and 15, they are allowed for the similar reasons as set forth above regarding independent claim 1. Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.” Claims 6-7 would be allowable if rewritten to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action and to include all of the limitations of the base claim and any intervening claims. Conclusion THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
