Office Action

§102 §103 §112
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 the Claims In the preliminary amendment dated February 6, 2024, claims 1-20 are pending. Claims 1-13 are amended and claims 14-20 are newly added. Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Drawings The drawings are objected to because certain numerals are unclear as to which feature they are indicating. Particularly: FIG. 4 – L1-L8, OPS, 114 FIG. 5 – 173, 162 FIG. 6 – 136, 173 Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 8-12 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Regarding claim 8, line 5 recites “closer to a first connection point the connection line and the first board”, however, this language is unclear as to what feature the switch is disclosed closer to. Claims 9-12 are rejected at least due to their dependency from a rejected claim. Claim Rejections - 35 USC § 102 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 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. Claims 1, 13-15, 17 and 20 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Akao EP3683917A1 (as cited in the IDS dated 9/18/2025). Regarding claim 1. Akao discloses a power supply apparatus (10) for an aerosol generating device (FIGS. 1 and 3), comprising: a power supply (12); a first board (second board 77); a second board (first board 76) separate from the first board (FIG. 85; ¶42); a first electric connector (41a, 41b) configured to be connected to a heater (21) configured to heat an aerosol source by consuming power supplied from the power supply (¶23); a charging integrated circuit (IC) (13) disposed on the first board (77) and including an input terminal (from inverter 61) and a charging terminal (output of charger 13) connected to the power supply (12), the charging IC (13) configured to convert power input to the input terminal (41a/b – input to the load) and to output power which is converted from the charging terminal (¶17); a second electric connector (43) disposed on the second board (76) and configured to be connected to an external power supply (60) and including a power supply terminal (43a/b); a power supply line (FIG. 7: connecting line between receptacle and charging IC) configured to connect the power supply terminal (43a/b) and the input terminal (FIG. 7: connecting line between receptacle 43a/b and charging IC13); and overvoltage protection circuitry (73) disposed only on the second board (76) of the first board and the second board and provided in the power supply line (¶61 – resistor 73 prevents high voltage from being input into charger 13). Regarding claim 13. Akao discloses a power supply apparatus (10) for an aerosol generating device (FIGS. 1 and 3), comprising: a power supply (12); a first board (second board 77); a second board (first board 76) separate from the first board (FIG. 85; ¶42); a first electric connector (41a, 41b) configured to be connected to a heater (21) configured to heat an aerosol source by consuming power supplied from the power supply (¶23); a charging integrated circuit (IC) (13) disposed on the first board (77) and including an input terminal (from inverter 61) and a charging terminal (output of charger 13) connected to the power supply (12), the charging IC configured to convert power input to the input terminal (from inverter 61) and to output power which is converted from the charging terminal (¶17); a second electric connector (43) disposed on the second board (76) and configured to be connected to an external power supply (60) and including a power supply terminal (43a/b); a power supply line (FIG. 7: connecting line between receptacle and charging IC) configured to connect the power supply terminal (43a/b) and the input terminal (FIG. 7: connecting line between receptacle 43a/b and charging IC13); and overvoltage protection circuity (73) provided in the power supply line, wherein a number of circuit components of the overvoltage protection circuitry disposed on the second board is larger than a number of circuit components of the overvoltage protection circuitry disposed on the first board (because the resistor 71 is provided on the second board 76, it follows that the number of components is larger on the board 76 than on board 77). Regarding claim 14. Akao discloses that the second electric connector (43) is disposed on a first surface of the second board (76), and the overvoltage protection circuitry (73) is disposed on a second surface of the second board that opposes the first surface (FIG. 5/7 because the resistor 73 is arranged on a surface it follows that the surface it may be designated on is a second surface, which would be opposite another surface). Regarding claim 15. Akao discloses that at least a part of the overvoltage protection circuitry (73) is disposed in a region in which the second electric connector (43) projects from a direction orthogonal to the second board (76) (FIG. 7 – the resistor 73 is arranged on the board 76 from which the connector 43 extends from). Regarding claim 17. Akao discloses that the controller (50) is disposed on the first board (77) (FIG. 7). Regarding claim 20. Akao discloses a power supply apparatus (10) for an aerosol generating device (FIGS. 1 and 3), comprising: a battery (12); a first electric connector (41a/b) configured to be connected to a heater (21) for heating an aerosol source by consuming power supplied from the power supply (¶23); a charging integrated circuit (IC) (13) disposed on the first board (77) and including an input terminal (from inverter 61), and a output terminal (output of charger 13) connected to the power supply (12), the charging IC (13) configured to convert power input to the input terminal (41a/b – input to the load) and to output power which is converted from the charging terminal (¶17); a second electric connector (43) including a power supply terminal (43a/b) and disposed on a second circuit board (76), wherein the second electric connector is configured to be connected to an external power supply (60); a power supply line (FIG. 7: connecting line between receptacle and charging IC) connecting the power supply terminal (43a/b) and the input terminal (FIG. 7: connecting line between receptacle 43a/b and charging IC13); and overvoltage protection circuitry (73) disposed on the second board (76) of the first board and the second board and provided in the power supply line (¶61 – resistor 73 prevents high voltage from being input into charger 13). 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. Claims 2-3, 5-12 and 18-19 are rejected under 35 U.S.C. 103 as being unpatentable over EP3683917A1. Regarding claim 2. Akao discloses that the second board (76) has a main surface (top of 76) and a secondary surface which is a back surface of the main surface (bottom of 76), the second electric connector (part of terminal 43) is disposed on the main surface (see annotated and reproduced FIG. 5 below), and PNG media_image1.png 274 273 media_image1.png Greyscale Although Akao does not explicitly teach that the overvoltage protection circuitry (73) is disposed on the secondary surface, Akao teaches arranging circuitry of a second side, such as 77b, in order to reduce electrostatic noise interfering with the overvoltage protection (¶84). It would be obvious to a person of ordinary skill in the art to provide the noise reduction in order to obtain a more accurate voltage detection to prevent overvoltage and damage to the system. Regarding claim 3. Akao discloses that at least a part of the overvoltage protection circuitry (73) is disposed in a region in which the second electric connector projects (43) from a direction orthogonal to the second board (76) (FIG. 5). Regarding claim 5. Akao discloses that the controller (50) is disposed on the first board (77) (FIG. 7). Regarding claim 6. Akao discloses a diode (71 – Zener diodes are known to function similar to that of a switch) configured to open and close the power supply line and provided between the overvoltage protection circuitry (73) and the input terminal (41a/b), wherein the diode (71) is provided on the first board (77). Although Akao discloses a Zener diode 71 rather than a switch, a Zener diode is known to function as a switch as it will block current until a reverse voltage reaches a threshold then it “switches” on. Thus, because a Zener diode is well-known to have a switch function, a person of ordinary skill in the art would understand that the diode may be used as a switch. Regarding claim 7. Akao discloses a controller (50) configured to control supply of power from the power supply to the first electric connector (77) (¶42), wherein the controller is configured to control opening and closing of the diode (71) (¶60 – controller controls the voltage operation thus providing control with the amount of voltage applied). Although Akao discloses a Zener diode 71 rather than a switch, a Zener diode is known to function as a switch as it will block current until a reverse voltage reaches a threshold then it “switches” on. Thus, because a Zener diode is well-known to have a switch function, a person of ordinary skill in the art would understand that the diode may be used as a switch. Regarding claim 8. Akao discloses that the power supply line includes a connection line (78) configured to connect the first board (77) and the second board (76); and the diode (71) is disposed closer to a first connection point the connection line and the first board, than the charging IC (it is uncertain as what feature the switch is supposed to be closer to as both the switch and the charging IC are arranged on the same board according to the combination of claims 1 and 6). Although Akao discloses a Zener diode 71 rather than a switch, a Zener diode is known to function as a switch as it will block current until a reverse voltage reaches a threshold then it “switches” on. Thus, because a Zener diode is well-known to have a switch function, a person of ordinary skill in the art would understand that the diode may be used as a switch. Regarding claim 9. Akao discloses that the diode (71) is provided at a position closer to the connection point than any IC disposed on the first board (77) (FIG. 7). Although Akao discloses a Zener diode 71 rather than a switch, a Zener diode is known to function as a switch as it will block current until a reverse voltage reaches a threshold then it “switches” on. Thus, because a Zener diode is well-known to have a switch function, a person of ordinary skill in the art would understand that the diode may be used as a switch. Regarding claim 10. Akao discloses that the second board (76) extends in a predetermined direction (FIGS. 3, 5, and 7), the second electric connector (43) is provided at one end in the predetermined direction (FIG. 7 – a predetermined direction is any direction in which the board extends), and a second connection point (43b) between the connection line (78) and the second board (76), is at a position closer to the second electric connector (43) than another end in the predetermined direction (as illustrated below in partially reproduced and annotated FIG. 7 below). PNG media_image2.png 340 444 media_image2.png Greyscale Regarding claim 11. Akao discloses a case (11) configured to accommodate the power supply (12), the charging IC (13), the power supply line (FIG. 7: connecting line between receptacle and charging IC), the overvoltage protection circuitry (73), the first board (77), the second board (76), and the diode (71)(FIG. 5); and a first connector configured to fix positions of the first board and the second board inside the case, and to mechanically connect the first board and the second board (FIG. 5 illustrates the first and second board being secured within the case 11 by setting in the groove provided along with pins arranged on the board 77 and held in place by the end of the case 11), wherein a position where the first connector and the second board connect is closer to the one end in the predetermined direction than the another end in the predetermined direction (FIG. 5 – the end of case 11, holding the circuit board 76 in place with relation to circuit board 77 is closer to the one end in the predetermined direction). Although Akao discloses a Zener diode 71 rather than a switch, a Zener diode is known to function as a switch as it will block current until a reverse voltage reaches a threshold then it “switches” on. Thus, because a Zener diode is well-known to have a switch function, a person of ordinary skill in the art would understand that the diode may be used as a switch. Regarding claim 12. Akao discloses a third electric connector configured to electrically connect the power supply (12) and the second board (76) (FIG. 7 – line extending from the connection of battery 12 that extends to the circuit board 76), wherein a position where the third electric connector and the second board connect is closer to the one end in the predetermined direction than the another end in the predetermined direction (the connection is closer to one side than the other). Regarding claim 18. Akao discloses a diode (71 – Zener diodes are known to function similar to that of a switch) configured to open and close the power supply line and provided between the overvoltage protection circuitry (73) and the input terminal (41a/b), wherein the switch (71) is provided on the first board (77). Although Akao discloses a Zener diode 71 rather than a switch, a Zener diode is known to function as a switch as it will block current until a reverse voltage reaches a threshold then it “switches” on. Thus, because a Zener diode is well-known to have a switch function, a person of ordinary skill in the art would understand that the diode may be used as a switch. Regarding claim 19. Akao discloses a controller (50) configured to control supply of power from the power supply to the first electric connector (77) (¶42), wherein the controller is configured to control opening and closing of the diode (71) (¶60 – controller controls the voltage operation thus providing control with the amount of voltage applied). Although Akao discloses a Zener diode 71 rather than a switch, a Zener diode is known to function as a switch as it will block current until a reverse voltage reaches a threshold then it “switches” on. Thus, because a Zener diode is well-known to have a switch function, a person of ordinary skill in the art would understand that the diode may be used as a switch. Claims 4 and 16 are rejected under 35 U.S.C. 103 as being unpatentable over EP3683917A1 in view of Chan US20100165528A1. Regarding claim 4 and claim 16. Akao discloses that the second electric connector (43) includes a data terminal (USB) (¶13). the power supply apparatus (10) further comprises a controller (50) configured to control supply of power from the power supply (12) to the first electric connector (77) (¶42). Akao does not explicitly disclose that a data line configured to connect the data terminal and the controller; and second overvoltage protection circuitry provided in the data line, wherein the second overvoltage protection circuitry is disposed on the main surface. Chan discloses a data line configured to connect the data terminal and the controller (¶37 – data line connects USB to controller 430); and second overvoltage protection circuitry provided in the data line (¶37 – detection circuitry 434 detects an overvoltage condition and deactivates the supply of power on that power line). When applying the circuit of Chan with the system of Akao, because the connector 43 is arranged on the main surface of the second board, it follows that the data line, with the second overvoltage protection circuitry is disposed on the main surface with the data line. It would be obvious to one of ordinary skill to provide the data line of Chan to the data communication of Akao in order to prevent overvoltage due to a short and prevent degradation (Chen; ¶37). Relevant Prior Art The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Ono et al. US20220007732A1 discloses an aerosol generation device having multiple circuit boards. Liu US20160058074A1 discloses an electronic cigarette having a data communication line via a USB terminal (¶132).
