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 § 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 1-2 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Nakao et al. (USPUB 2021/0159731).
As to Claim 1, Nakao discloses a control device for a power receiving device including a power receiving coil that receives power transmitted from a power transmitting coil of the power transmitting device in a contactless manner, wherein when the control device performs a short-circuit mode in which a switching element provided between the power receiving coil and a load is operated to short-circuit a portion between output terminals of the power receiving coil, the control device performs the short-circuit mode such that a region in which a phase of a current in an inverter of the power transmitting device is advanced is avoided (Paragraph 228, Delayed is the advanced avoided).
As to Claim 2, Nakao discloses the control device according to claim 1, wherein the control device determines a switching timing of the switching element in the short-circuit mode such that, by executing the short-circuit mode, the phase of the current of the inverter is shifted in a direction in which the phase of the current of the inverter is delayed (Paragraph 228).
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 3 is rejected under 35 U.S.C. 103 as being unpatentable over Nakao et al. in view of Ushijima et al. (USPUB 2019/0214853).
As to Claim 3, Nakao discloses the control device according to claim 1, wherein when the control device performs the short-circuit mode, the control device controls a swing timing of the switching element in the short-circuit mode (Paragraph 228). Nakao does not expressly disclose a rectangular wave. Ushijima discloses that a left side of a voltage rectangular wave on a power receiving side is trimmed more than a right side of the voltage rectangular wave on the power receiving side is trimmed (Figure 8, Delay). It would have been obvious to one having ordinary skill in the art at the time of this invention to trim the left side of the wave, as taught by Ushijima, in order to delay the wave form of Nakao.
