Claim Rejections - 35 USC § 103 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. 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claim(s) 80 is/are rejected under 35 U.S.C. 103 as being unpatentable over Park (pub # 20160292563) in view of Mars et al (U.S. Pat # 12,328,581). Consider claim 80. Park does not specifically disclose The wearable device of claim 78, further comprising one or more energy harvesting devices, wherein the one or more energy harvesting devices are configured to transmit electric power to the one or more power storage devices, and wherein the one or more energy harvesting devices includes at least one of a thermoelectric generator or a transducer. However Mars et al in at least col. 4 lines 3-13 discloses “In various embodiments, power management and charging circuitry is typically provided to control charging of the power supply. In some examples, charging may be facilitated by and external power source, such as an electrical source, magnetic source, radio frequency (rf) source, NFC (e.g. Qi Charger), light or laser source, heat source, or the like. In various cases, the charging circuitry may include components appropriate for the charging source, such as electrical contacts, metal coils, solar or light power conversion regions, thermoelectric generation components, or the like”, thus a harvesting device including a thermoelectric generator. Therefore it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the features of Mars et al with the invention of Park in order to provide an efficient and cost effective method of charging the wearable device. Claim(s) 89-90 and 96-97 is/are rejected under 35 U.S.C. 103 as being unpatentable over Park (pub # 20160292563) in view of Ding et al (pub # 20200227954). Consider claims 89 and 96. Park does not specifically disclose wherein the one or more receiver devices includes an electromagnet, wherein the electromagnet includes at least one of a solenoid, a servomotor, a stepper motor, or a motor. However Ding et al in at least paragraph 0045 discloses an electromagnet 140 that may be a solenoid. Therefore it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the electromagnet of Ding et al with the wearable device of Park in order to increase the efficiency of charging (Ding et al paragraph 0012). Consider claims 90 and 97. Ding et al further teaches The system of claim 89, wherein the one or more receiver devices includes a memory that stores instructions executable by one or more processors of the one or more receiver devices, which when executed cause the one or more receiver devices to: detect a position of the electromagnet; (paragraph 0052, if a communication packet indicates a device type that uses magnetic positioning, and/or the wireless charger 110 detects a magnet of the mobile device (e.g., a permanent magnet)). actuate the electromagnet; (paragraph 0052, the wireless charger 110 may energize the electromagnet 140). and reconfigure the position of the electromagnet. (paragraph 0052, the wireless charger 110 may energize the electromagnet 140 so as to draw the mobile device towards an alignment position (e.g., alignment position 220 as shown in FIGS. 2A-2B)). Claim(s) 91 and 92 is/are rejected under 35 U.S.C. 103 as being unpatentable over Park (pub # 20160292563) in view of Ding et al (pub # 20200227954) and further in view of Zeine (pub # 20200295598). Consider claim 91. Park in view of Ding et al does not specifically disclose The system of claim 89, wherein the one or more receiver devices is configured to be installed over a toggle light switch such that the toggle light switch can be (1) operated in response to the signal from the one or more output devices and (2) manually operated by a user. However Zeine in at least Fig. 4 and paragraph 0033 discloses a wireless signaling device 444 installed over a toggle light switch that sends and receives signals to a light control component 454 for turning on or off the light device that the switch is connected to. Therefore it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the features of Zeine with the invention of Park in view of Ding et al because wireless power is desirable (Zeine paragraph 0042). Consider claim 92. Park in view of Ding et al does not specifically disclose The system of claim 89, wherein the one or more receiver devices includes magnets configured to magnetically couple the one or more receiver devices to a toggle light switch. However Zeine in at least Fig. 4 and paragraph 0033 discloses a wireless signaling device 444 installed over a toggle light switch that sends and receives signals to a light control component 454 for turning on or off the light device that the switch is connected to. Therefore it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the features of Zeine with the invention of Park in view of Ding et al because wireless power is desirable (Zeine paragraph 0042).
