Office Action

§102
DETAILED ACTION This office action is in response to the application filed on 5/2/24. 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 . 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. Inventorship This application currently names joint inventors. In considering patentability of the claims under 35 U.S.C. 103(a), the examiner presumes that the subject matter of the various claims was commonly owned at the time any inventions covered therein were made absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and invention dates of each claim that was not commonly owned at the time a later invention was made in order for the examiner to consider the applicability of 35 U.S.C. 103(c) and potential 35 U.S.C. 102(e), (f) or (g) prior art under 35 U.S.C. 103(a). Specification Applicant is reminded of the proper content of an abstract of the disclosure. The abstract should be in narrative form and generally limited to a single paragraph on a separate sheet within the range of 50 to 150 words. The form and legal phraseology often used in patent claims, such as "means" and "said," should be avoided. The abstract should describe the disclosure sufficiently to assist readers in deciding whether there is a need for consulting the full patent text for details. The language should be clear and concise and should not repeat information given in the title. It should avoid using phrases which can be implied, such as, "The disclosure concerns," "The disclosure defined by this invention," "The disclosure describes," etc. The abstract of the disclosure is objected to because it does not describe the disclosure sufficiently to assist readers in deciding whether there is a need for consulting the full patent text for details. Correction is required. See MPEP § 608.01(b). 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 Objections Claims 2-6 and 8-10 are objected to because of the following informalities: In regards to claim 2, it appears that “the number of times of receptions” should be “a number of times of receptions”. In regards to claim 3, it appears that “the number of times of the first request” should be “a number of times of the first request”. In regards to claim 4, it appears that “the second request t, and transmits” should be “the second request, and transmits”. In regards to claim 5, it appears that “the number of times of the temporary instruction” should be “a number of times of the temporary instruction”. In regards to claim 6, it appears that “the number of times of the received responses” should be “a number of times of the received responses”. In regards to claim 8, it appears that “the number of times of responses” should be “a number of times of responses”. In regards to claim 9, it appears that “the power transmission apparatus” should be “a power transmission apparatus”. In regards to claim 10, it appears that “the power transmission apparatus” should be “a power transmission apparatus”. 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. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claims 1, 6, 7, 9 and 10 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Ikefuji (US20150280453). Regarding Claim 1, Ikefuji discloses a power reception apparatus (fig. 2, 4, 18) comprising: a power reception unit (RR) configured to wirelessly receive power from a power transmission apparatus (TT); and a communication unit (100) configured to transmit a first request (510) to the power transmission apparatus, configured to receive from the power transmission apparatus a response (520) for the first request, and configured to transmit a second request (S116) for stopping a power transfer to the power transmission apparatus based on the received response (via 110, fig. 18). Regarding Claim 6, Ikefuji discloses the first request (510) includes information regarding a number of times of the received responses (after 510 is transmitted then when S104 = N, 510 would include the “N” input therefore “information” of a time of the received response). Regarding Claim 7, Ikefuji discloses the first request includes information regarding a response for a request of the power reception apparatus (¶134) Regarding Claim 9, Ikefuji discloses a method for a power reception apparatus (fig. 2, 4, 18), the method comprising: transmitting a first request (510) to a power transmission apparatus (TT); receiving from the power transmission apparatus a response for the first request (520); and transmitting a second request (S116) for stopping a power transfer to the power transmission apparatus based on the received response (via 110, fig. 18). Regarding Claim 10, Ikefuji discloses a non-transitory computer-readable storage medium storing a program (¶341) for causing a computer to perform a method for a power reception apparatus (fig. 2, 4, 18), the method comprising: transmitting a first request (510) to the power transmission apparatus; receiving from the power transmission apparatus a response (520) for the first request; and transmitting a second request (S116) for stopping a power transfer to the power transmission apparatus based on the received response (via 110, fig. 18). Allowable Subject Matter Claims 2-5 and 8 would be allowable if rewritten to overcome the objection(s) set forth in this Office action and to include all of the limitations of the base claim and any intervening claims. The following is a statement of reasons for the indication of allowable subject matter: Regarding claim 2, the prior art fails to disclose: “...the communication unit transmits the second request in a case where the received response does not correspond to the number of times of receptions.” in combination with the additionally claimed features, as are claimed by the Applicant. Regarding claim 5, the prior art fails to disclose: “...a detection unit configured to detect temporary interruption of the transmission of power from the power transmission apparatus, wherein, in a case where the received response corresponds to the number of times of the temporary interruption, the communication unit does not transmit the second request.” in combination with the additionally claimed features, as are claimed by the Applicant. Regarding claim 8, the prior art fails to disclose: “...the communication unit receives the response for the first request, including information regarding the number of times of responses of the power transmission apparatus, and wherein, in a case where the received response does not correspond to the number of times of the responses included in the received response, the communication unit transmit the second request” in combination with the additionally claimed features, as are claimed by the Applicant. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure: US 12212160, Moritomo; Kazuo discloses a power transmission apparatus, power reception apparatus, control method performed by power transmission apparatus, control method performed by power reception apparatus, and storage medium US 12316138, Hiramatsu; Tomoki discloses a power transmission apparatus and power reception apparatus US 12395013, Shichino; Takahiro discloses a power transmission apparatus, power reception apparatus, method, and storage medium US 20190148967, Bae; Su Ho discloses a wireless power control method and device US 20230084679, Lee; Minsoo et al. discloses an apparatus and method enabling out-band communication in wireless charging apparatus, method and system.
