Regarding claim 15, NAHUM, VICK, MATSUMOTO disclose the wireless power transfer relay of Claim 1 as discussed above, However NAHUM, VICK, MATSUMOTO do not disclose further comprising:
a microcontroller unit connected to the relay transmitter coil, the microcontroller unit configured to monitor an operating frequency of the wireless power transmitter or the mobile electronic device.
GUANGPING discloses a wireless power transfer relay, further comprising an adjustable impedance matching circuit attached to the relay receiver coil, the impedance matching circuit is adjusted based on the operating frequency of the wireless power transmitter (See Fig.2, Items:C1, C2, Pars.66 and 92, discloses “According to the operating frequency of the wireless charging transmitting device 100, the impedance matching network circuit is adjusted. When the resonant frequency point corresponding to the capacitance value of the impedance matching network circuit approaches the operating frequency, the impedance matching network circuit reaches the optimal impedance value”. This implicitly indicates that a controller is present to monitor the wireless power transmitter operating frequency and to adjust the impedance matching network to match the operating frequency of the wireless power transmitter. The examiner further explains that MATSUMOTO discloses the adjustable capacitor and the inductance are controlled such that charging efficiency is improved).
NAHUM, VICK, MATSUMOTO and GUANGPING are analogous art since they all deal with wireless charging.
It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the invention disclosed by NAHUM and VICK with the teachings of GUANGPING by adding the dynamic impedance matching circuit for the benefit of improving the charging efficiency (See GUANGPING, Par.95).
Claim(s) 7 is/are rejected under 35 U.S.C. 103 as being unpatentable over NAHUM in view of VICK and MATSUMOTO and in further view of MORA et al. (US 2023/0261520 A1, hereinafter MORA).
Regarding claim 7, NAHUM, VICK and MATSUMOTO disclose the wireless power transfer relay of Claim 1 as discussed above, However, NAHUM, VICK and MATSUMOTO do not disclose further comprising: one or more magnet arrays coupled to one or more of the receiving platform or the transmitting platform for position alignment.
MORA discloses a wallet to facilitate charging of a mobile electronic device, the wallet further comprising one or more magnet arrays coupled to one or more of the receiving platform or the transmitting platform for position alignment (See Fig.11, and Par.53, disclose a wallet 1100 comprising a magnetic array 1132 and a magnet 1134 to align the wallet 1100 to the mobile device 1102).
NAHUM, VICK, MATSUMOTO and MORA are analogous art since they all deal accessories which facilitate charging of a mobile device.
It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the invention disclosed by NAHUM, VICK and MATSUMOTO with the teachings of MORA by adding the disclosed magnetic array for the benefit of aligning and securing the wallet to the mobile electronic device.
Claim(s) 8 is/are rejected under 35 U.S.C. 103 as being unpatentable over NAHUM in view of VICK and MATSUMOTO and in further view of HUANG (US 2015/0214993 A1, hereinafter HUANG).
Regarding claim 8, NAHUM, VICK and MATSUMOTO disclose the wireless power transfer relay of Claim 1 as discussed above, However, NAHUM, VICK and MATSUMOTO do not disclose further comprising: a pair of near-field communication (NFC) relay coils configured to relay an NFC signal between the wireless power transmitter and the mobile electronic device.
HUANG discloses an accessory comprising a pair of near-field communication (NFC) relay coils configured to relay an NFC signal between the wireless power transmitter and the mobile electronic device (See Pars.14, 16 and 19-20, disclose an accessory comprising a pair of NFC antennas placed on front side and back side of the accessory, the antennas are configured to receive NFC communication from one side and relay to the other side via electrical connection and the other side then retransmits the signal. Fig.14, discloses the accessory [case comprising battery pack, as shown in Fig.1, Item#100] is placed in between an electronic device and an external power charger).
NAHUM, VICK, MATSUMOTO and HUANG are analogous art since they all deal with mobile device accessories.
It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the invention disclosed by NAHUM, VICK and MATSUMOTO with the teachings of HUANG by adding a pair of NFC relay coils to relay an NFC signal between the wireless power transmitter and the mobile electronic device for the benefit of ensuring undegraded communication between the wireless power transmitter and the mobile electronic device.
