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 . Status of Claims This Office Action is in response to the application filed on 4/29/2025. Claims 1-30 are presently pending and are presented for examination. 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)(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 1-9,11-20,23-25 and 27-29 is/are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Xu (US 20220078779). As to claim 1, Xu discloses a method of wireless communication performed by a first wireless communication device (Methods in fig. 3-4,7 and 11.

During the communication with the DT primary serving gNB, the user can report basic information to it (i.e. Fig. 11 “Report basic information”) , including the energy status of the device terminal. Once the user equipment detects that its remaining power is lower than a certain threshold, it can actively report the EH request to the primary serving gNB (i.e. Fig. 11 “Report EH request”). [0114] If the DT primary serving gNB is the base station closest to the EH user, there is no need to switch the primary serving base station); receiving, from the second wireless communication device in response to the at least one of the energy request or the energy level indication, an indication of one or more resources (“information on the resource for energy harvesting”) for receiving a radio frequency (RF) energy harvesting signal (Fig. 11 “Report current SFI” to “select new frame structure” to “transmit handshake information. [0038]-[0042] .. the information on the resource for energy harvesting may include indication information on a frame structure of the wireless signal. The indication information may include, for example, a Slot Format Indication (SFI), which is a bit sequence used to indicate the time slot format…. the time-frequency resource… symbols for energy harvesting… downlink symbols for data transmission….and symbols for energy harvesting (which hereinafter may be referred to as EH symbols) in the frame structure of the wireless signal..

As to claims 24 and 28, it is based on the rejection of claims 5 and 15 and is similarly rejected. As to claim 25 and 29, it is based on the rejection of claims 8 and 19 and is similarly rejected. 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 10,21,26, and 30 is/are rejected under 35 U.S.C. 103 as being unpatentable over Xu (US 20220078779) in view of Moyer (US 20150333530). As to claims 10 and 26, Xu discloses the method of claim 1. Xu does not disclose/teach entering a sleep mode after transmitting the at least one of the energy request or the energy level indication and detecting a wake-up signal (WUS) while in the sleep mode. Moyer teaches entering a sleep mode after transmitting the at least one of the energy request or the energy level indication ([0033] Additionally or alternatively, the receiver device 304 can transmit a signal indicating the battery is charged, and in response the transmitter device may enter a low power or sleep state) and detecting a wake-up signal (WUS) while in the sleep mode ([0040] hen the transmitter device 402 is in a low power or sleep state, the transmitter device 402 may wake up periodically. It would have been obvious to a person of ordinary skill in the art to modify the method of Xu to enter a sleep mode after transmitting the at least one of the energy request or the energy level indication and detecting a wake-up signal (WUS) while in the sleep mode in order to reducing power consumption and waste energy. Xu in view of Moyer does not disclose/teach wherein the receiving the indication of the one or more resources is based on detecting the WUS However it would have been obvious to a person of ordinary skill in the art to modify the electronic device to wherein the receiving the indication of the one or more resources is based on detecting the WUS in order to for the electronic device to properly operate. As to claims 21 and 30, Xu discloses the method of claim 11. Xu does not disclose/teach detecting the second wireless communication device is operating in a sleep mode; and transmitting, to the second wireless communication device, a wake-up signal (WUS). Moyer teaches detecting the second wireless communication device is operating in a sleep mode ([0033] Additionally or alternatively, the receiver device 304 can transmit a signal indicating the battery is charged, and in response the transmitter device may enter a low power or sleep state) and transmitting, to the second wireless communication device, a wake-up signal (WUS) ([0040] hen the transmitter device 402 is in a low power or sleep state, the transmitter device 402 may wake up periodically. It would have been obvious to a person of ordinary skill in the art to modify the method of Xu to detecting the second wireless communication device is operating in a sleep mode; and transmitting, to the second wireless communication device, a wake-up signal (WUS) in order to reducing power consumption and waste energy. Xu in view of Moyer does not disclose/teach wherein the receiving the indication of the one or more resources is based on detecting the WUS However it would have been obvious to a person of ordinary skill in the art to modify the electronic device to wherein the transmitting the indication of the one or more resources is based on the WUS in order to for the electronic device to properly operate. Allowable Subject Matter Claim 22 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. The following is a statement of reasons for the indication of allowable subject matter: Regarding dependent claim 22, Although the prior art discloses refraining, based on the at least one of the energy request or the energy level indication, from scheduling a communication with the second wireless communication device, the prior art of record does not disclose or teach the combination of: “refraining, based on the at least one of the energy request or the energy level indication, from scheduling a communication with the second wireless communication device.” 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.” Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to TYNESE V MCDANIEL whose telephone number is (313)446-6579.
