Office Action

§102 §103 §112
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 . 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 5 - 8 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 5, applicant attempts to define the subject matter in terms of the result to be achieved (estimates output power of the main rectifier circuit unit based on a measurement result of the measurement unit.), but in so doing merely states the problem to be solved, without indicating the technical features or steps necessary for achieving this result. Due to lack of essential features or steps it is unclear how the applicant is estimating output power of the main rectifier circuit unit. Claims 6 is rejected by virtue of the dependency on claim 5. As to claim 7, applicant attempts to define the subject matter in terms of the result to be achieved (estimating output power of the main rectifier circuit unit… ), but in so doing merely states the problem to be solved, without indicating the technical features or steps necessary for achieving this result. Due to lack of essential features or steps it is unclear how the applicant is estimating output power of the main rectifier circuit unit. Claims 8 is rejected by virtue of the dependency on claim 7. Claim Rejections - 35 USC § 102 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. (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. Claim(s) 1, 3 - 5 and 7 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by OSHIMA et al. (2019/0305613). As to claim 1, OSHIMA et al. (hereinafter OSHIMA) discloses a wireless power reception device and wireless power transmission system comprising a power reception apparatus (20) comprising: a main rectifier circuit unit (RT1) that rectifies received power (RT1I1) and outputs rectified power to a load (Vload); a sub rectifier circuit unit (RT2) connected in parallel with a power reception unit (RT1I1) of the main rectifier circuit unit (RT1); and a measurement unit (23) that measures power of an output unit (VD2) of the sub rectifier circuit unit (RT2) (Fig. 2), [0037] – [0063]. PNG media_image1.png 576 742 media_image1.png Greyscale As to claim 3, OSHIMA discloses the sub rectifier circuit unit (RT2) includes: a rectifier circuit (RT2) including the output unit (VD2); an inductor (L2) provided between the power reception unit and a ground (G); and a capacitor (C2) including one end connected to the power reception unit (RT1I1) and the other end connected to the rectifier circuit (RT2) (Fig. 1 and 2). As to claim 4, OSHIMA discloses that the measurement unit (23) measures an output voltage (VD2) of the sub rectifier circuit unit (RT2). As to claim 5, OSHIMA discloses an estimation unit (23A) that estimates output power of the main rectifier circuit unit (RT1) based on a measurement result of the measurement unit (23), (Fig. 3). As to claim 7, OSHIMA discloses a wireless power reception device and wireless power transmission system comprising the power reception apparatus (20) including a main rectifier circuit unit (RT1) that rectifies received power (RT1I1) and outputs rectified power to a load (Vload), and a sub rectifier circuit unit (RT2) connected in parallel to a power reception unit (RT1I1) of the main rectifier circuit unit (RT1), the method comprising: measuring (23) power of an output unit (VD2) of the sub rectifier circuit unit (RT2); and estimating (23A) output power of the main rectifier circuit unit (RT1) based on a measurement result of the power (VD2) (Fig. 2), [0037]-[0063]. Claim Rejections - 35 USC § 103 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) 2 and 8 is/are rejected under 35 U.S.C. 103 as being unpatentable over OSHIMA et al. (2019/0305613). As to claims 2 and 8, OSHIMA fails to explicitly disclose that the sub rectifier circuit unit has an input impedance larger than an input impedance of the main rectifier circuit unit. However, at the time of the invention, it would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art such that the input impedance of the sub-rectifier circuit higher than the input impedance of the main rectifier circuit would have been a matter of choice which a person of ordinary skill in the art would have found obvious absent persuasive evidence that the particular configuration of the claimed feature was significant. (Please Note MPEP 2144 IV. B). Prior Art of Record The prior art made of record and not relied upon is considered pertinent to applicant s disclosure. Chen et al. (2020/0412169) is cited for its disclosure of a wireless power reception apparatus and mobile terminal. Chen et al. (11,949,275) is cited for its disclosure of a wireless power reception apparatus and mobile terminal.
