Office Action

§102 §112
DETAILED ACTION 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 14-20 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. Claim 14 repeatedly recites orientation of the pump elements using the term “side”. However, the descriptions of these sides have multiple modifiers, as detailed below: “a circuit board located at the housing at another side in an axial direction” in lines 8-9 “a pump portion coupled to the rotor at one side in an axial direction” in lines 10-11 “a partition wall portion provided to cover the rotor from another side in an axial direction” in lines 12-13 “the housing includes an upper wall portion located at the partition wall portion at the other side in the axial direction” in lines 15-16 Therefore, the claim limitations are indefinite because without consistency of claim terms it is unclear how the elements are oriented relative to one another within the pump assembly. Thus, claim 14 is indefinite. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claims 1-5 and 8 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Irie 10,077,781.

Claims 9 and 12 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Bernreuther US 2019/0109516 A1 Bernreuther discloses, regarding claim 9, an electric pump 1 comprising: a shaft 2 extending in an axial direction; a rotatable rotor 3 located at an outer side of the shaft 2 in a radial direction; a stator 20 located at an outer side of the rotor 3 in the radial direction and surrounding the rotor 3; a housing (comprising elements 11 and 19) to accommodate the rotor 3 and the stator 20; a pump portion (see impeller end of 3 within 7) coupled to the rotor 3 at one side in an axial direction; and a circuit board 4 located at the housing 11/19 at another side in an axial direction; wherein the housing 11/19 includes an upper wall portion 11 located more toward another side in an axial direction than the rotor 3 and the stator 20; the circuit board 4 is located more toward another side in an axial direction than the upper wall portion 11; and the upper wall portion 11 includes a heat transfer plane (substantially broad, the examiner has interpreted said plane as the plane of element 11 with the same thickness, extending radially from the axis of 2) extending along a first surface opposing one side of the circuit board 4 in the axial direction (clearly shown in Fig. 1), the heat transfer plane (of 11) opposing another side in an axial direction (clearly shown in Fig. 1); Re claim 12, further comprising: a fixing portion 9 (which comprises spokes 23) configured to fix an end portion of the shaft 2 at one side in an axial direction and the pump portion (see impeller end of 3 within 7); wherein the fixing portion 9 is exposed to an inside of the pump portion (7). Allowable Subject Matter Claim 7 is objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Claims 15-20 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.
