Detector 160 may be two or more detectors such as detectors 262 & 264. 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. Claims 10-11 & 13 are rejected under 35 U.S.C. 103 as being unpatentable over Jung et al. (US Patent Application Publication # 2021/0007393) in view of Butin et al. (US Patent Application Publication # 2022/0369714). Regarding Claim 10, Jung does not explicitly disclose a positive-side connector to which one end of the coil is connected; and a negative-side connector to which the other end of the coil is connected, wherein the first detection circuit includes: a first resistor having one end connected to the positive-side connector; a second resistor having one end connected to the negative-side connector and the other end connected to the ground; a switch device having one end connected to the other end of the first resistor and the other end connected to the other end of the second resistor; a first detector configured to detect a voltage applied to both ends of the first resistor; and a second detector configured to detect a voltage applied to both ends of the second resistor. Butin teaches a positive-side connector to which one end of the coil is connected; and a negative-side connector to which the other end of the coil is connected, wherein the first detection circuit (i.e. current measurement device 140 w/ switch 130) includes: a first resistor (i.e. current measurement device 140 may comprise a resistance) having one end connected to the positive-side connector; a second resistor having one end connected to the negative-side connector and the other end connected to the ground; a switch device (i.e. switch 130) having one end connected to the other end of the first resistor and the other end connected to the other end of the second resistor; a first detector configured to detect a voltage applied to both ends of the first resistor; and a second detector configured to detect a voltage applied to both ends of the second resistor (Fig. 3; Paragraphs 0016-0018, 0043, 0128-0129, 0134, 0228, 0313, 0315-0324). Butin teaches that it is well known in the art of aerosol-generating devices or vaporizers to use resistors with switches as part of detection circuits which detect at least one property of the inductive heating arrangement such as voltage. Jung discloses a detection circuit for detecting a magnitude of a voltage, but is silent on the specific components of the circuit. It would have been obvious to one skilled in the art to use to use resistors with switches as part of the detection circuits of Jung, as taught by Butin, in order to reliably measure the voltage induced in the coil. Regarding Claim 11, Jung does not explicitly disclose a positive-side connector to which one end of the coil is connected; and a negative-side connector to which the other end of the coil is connected, wherein the first detection circuit includes: a switch device having one end connected to the positive-side connector; a resistor having one end connected to the negative-side connector and the other end connected to the other end of the switch device; and a bidirectional current sense amplifier connected to both ends of the resistor and configured to detect a current flowing through the resistor and a direction thereof. Butin teaches a positive-side connector to which one end of the coil is connected; and a negative-side connector to which the other end of the coil is connected, wherein the first detection circuit (i.e. current measurement device 140 w/ switch 130) includes: a switch device (i.e. switch 130) having one end connected to the positive-side connector; a resistor (i.e. current measurement device 140 may comprise a resistance and a shunt amplifier) having one end connected to the negative-side connector and the other end connected to the other end of the switch device; and a bidirectional current sense amplifier (i.e. shunt amplifier) connected to both ends of the resistor and configured to detect a current (i.e. IDC) flowing through the resistor and a direction thereof (Fig. 3; Paragraphs 0043, 0134, 0313, 0315-0322). Butin teaches that it is well known in the art of aerosol-generating devices or vaporizers to use a shunt amplifier, otherwise known as a current sense amplifier, and a resistor with a switch as a detection circuit. Jung discloses a detection circuit for detecting a current, but is silent on the specific components of the circuit. It would have been obvious to one skilled in the art to use a bidirectional current sense amplifier, a resistor, and a switch device as components of the first detection circuit of Jung, as taught by Butin, in order to reliably measure the current induced in the coil. Regarding Claim 13, Jung discloses a positive-side connector to which one end of the coil (i.e. transmission coil & detection coil of detector 160 or detectors 262/264) is connected; a negative-side connector to which the other end of the coil is connected; and an inverter (i.e. adapter) configured to convert a direct current supplied from the power supply (i.e. battery 150) into an alternating current and including a positive-side output terminal and a negative-side output terminal (Paragraphs 0093-0095, 0107). Jung does not explicitly disclose that the first detection circuit includes: a first resistor configured to connect the positive-side connector and the positive-side output terminal; a second resistor configured to connect the negative-side connector and the negative-side output terminal; a first detector configured to detect a voltage applied to both ends of the first resistor; and a second detector configured to detect a voltage applied to both ends of the second resistor Butin teaches that the first detection circuit (i.e. current measurement device 140 w/ switch 130) includes: a first resistor (i.e. current measurement device 140 may comprise a resistance) having one end connected to the positive-side connector; a second resistor having one end connected to the negative-side connector and the other end connected to the ground; a switch device (i.e. switch 130) having one end connected to the other end of the first resistor and the other end connected to the other end of the second resistor; a first detector configured to detect a voltage applied to both ends of the first resistor; and a second detector configured to detect a voltage applied to both ends of the second resistor (Fig. 3; Paragraphs 0016-0018, 0043, 0128-0129, 0134, 0228, 0313, 0315-0324). Butin teaches that it is well known in the art of aerosol-generating devices or vaporizers to use resistors as part of detection circuits which detect at least one property of the inductive heating arrangement such as voltage. Jung discloses a detection circuit for detecting a magnitude of a voltage, but is silent on the specific components of the circuit. It would have been obvious to one skilled in the art to use to use resistors as part of the detection circuits of Jung, as taught by Butin, in order to reliably measure the voltage induced in the coil. Claim 12 is rejected under 35 U.S.C. 103 as being unpatentable over Jung et al. (US Patent Application Publication # 2021/0007393) in view of Sur (US Patent Application Publication # 2020/0253287). Regarding Claim 12, Jung does not explicitly disclose a negative power supply generating circuit configured to generate a negative voltage based on the power supplied from the power supply; a positive-side connector to which one end of the coil is connected; and a negative-side connector to which the other end of the coil is connected, wherein the first detection circuit includes: a switch device having one end connected to the positive-side connector; a resistor having one end connected to the negative-side connector and the other end connected to the other end of the switch device; and an operational amplifier having one of an inverting input terminal and a non-inverting input terminal connected to one end of the resistor, the other of the inverting input terminal and the non-inverting input terminal connected to the other end of the resistor, and the negative voltage supplied to a negative power supply terminal. Sur teaches a negative power supply generating circuit (i.e. inverter 710) configured to generate a negative voltage (i.e. complementary negative voltage) based on the power supplied from the power supply (i.e. power source 704); a positive-side connector (i.e. one of second terminals 718) to which one end of the coil (i.e. heating element 716 which may be an inductive coil) is connected; and a negative-side connector (i.e. another one of second terminals 718) to which the other end of the coil is connected, wherein the first detection circuit includes: a switch device having one end connected to the positive-side connector; a resistor (i.e. resistor R1) having one end connected to the negative-side connector and the other end connected to the other end of the switch device; and an operational amplifier (i.e. operational amplifier of non-inverting amplifier circuit 712) having one of an inverting input terminal (i.e. inverting input (-) of the operational amplifier) and a non-inverting input (i.e. non-inverting input (+) of the operational amplifier) terminal connected to one end of the resistor, the other of the inverting input terminal and the non-inverting input terminal connected to the other end of the resistor, and the negative voltage supplied to a negative power supply terminal (Fig. 7-9; Abstract; Paragraphs 0113-0127). Sur teaches that it is well known in the art of aerosol-generating devices or vaporizers to use an operational amplifier and a resistor with a switch along with an inverter as a detection circuit and as part of a control component of a power supply. Jung discloses power supply and control circuit but is silent on the specific components of the circuit. It would have been obvious to one skilled in the art to use a negative power supply generating circuit such as an inverter with an operational amplifier and a resistor as components of the power supply and control circuit of Jung, as taught by Sur, in order to reliably control and provide power in the aerosol-generating device.
