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 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) 4-8, 14, 15 is/are rejected under 35 U.S.C. 103 as being unpatentable over Yamaguchi in view of Lord [US 20180153223]. As to Claim 4 Yamaguchi fails to disclose The aerosol generating device of claim 1, wherein the controller includes: a ground terminal connected to the 1-1st contact electrode; and a general-purpose input and output terminal connected to the 1-2nd contact electrode. Lord teaches an electric vapor provision device comprising a cover 2 detachably coupled to a main body 8, [fig.1, 0033]; wherein the cover 2 comprises contact terminals 30, 34 electrically connected through a vaporizer 24, [fig. 3, 0034], and the main body 8 comprises terminals 28, 32 arranged to couple with the cover terminals 30, 34, [fig. 3, 0034], and a computer 12 to detect if the cover 2 is connected with the body 8, [0036]; wherein one of the contacts 28 or 32 is connected to a negative terminal of the power cell 10 and the other terminal is connected to a input of the computer 12, [fig. 10]. It would have been obvious for one of ordinary skill in the art at the time of the filing of the claimed invention to combine the teachings of Yamaguchi with that of Lord so that the system can be implemented using a basic circuit arrangement where a negative terminal of a power supply is used as a reference point for measuring electrical levels in the circuit. As to Claim 5 Yamaguchi discloses The aerosol generating device of claim 4, wherein the controller is further configured to transmit an output signal of a high level through the general-purpose input and output terminal, [0099] cover detected with a signal having predetermined value is detected. As to Claim 6 Yamaguchi discloses The aerosol generating device of claim 5, wherein the controller is further configured to, when the controller receives an input signal of a low level through the general-purpose input and output terminal, determine that the cover is mounted on the main body, [0099] cover detected when a voltage drop is detected. As to Claim 7 Yamaguchi fails to disclose The aerosol generating device of claim 5, further comprising an analog-to-digital converter between the 1-2nd contact electrode and the general-purpose input and output terminal, the analog-to-digital converter being configured to convert an analog input signal to a digital input signal. Lord teaches an electric vapor provision device comprising a cover 2 detachably coupled to a main body 8, [fig.1, 0033]; wherein the cover 2 comprises contact terminals 30, 34 electrically connected through a vaporizer 24, [fig. 3, 0034], and the main body 8 comprises terminals 28, 32 arranged to couple with the cover terminals 30, 34, [fig. 3, 0034], and a computer 12 to detect if the cover 2 is connected with the body 8, [0036]; wherein the system uses a digital multimeter 44 to determine if the cover is connected, [fig. 10, 0039]; which requires an analog to digital converter to convert the analog signal through the capacitor 38 into a digital format for the digital multimeter. It would have been obvious for one of ordinary skill in the art at the time of the filing of the claimed invention to combine the teachings of Yamaguchi with that of Lord so that the system of Lord can perform the digital comparison. As to Claim 8 Yamaguchi discloses The aerosol generating device of claim 7, wherein the controller is further configured to, when the general-purpose input and output terminal receives the input signal that is less than or equal to a predetermined threshold value, determine that the cover is mounted on the main body, [0099] cover detected when a signal drops to a predetermined value. Yamaguchi fails to disclose wherein the signal is digital. Lord teaches an electric vapor provision device comprising a cover 2 detachably coupled to a main body 8, [fig.1, 0033]; wherein the cover 2 comprises contact terminals 30, 34 electrically connected through a vaporizer 24, [fig. 3, 0034], and the main body 8 comprises terminals 28, 32 arranged to couple with the cover terminals 30, 34, [fig. 3, 0034], and a computer 12 comprising a microprocessor 16, [0051], to detect if the cover 2 is connected with the body 8, [0036]; wherein the system uses a digital multimeter 44 to determine if the cover is connected, [fig. 10, 0039]. It would have been obvious for one of ordinary skill in the art at the time of the filing of the claimed invention to combine the teachings of Yamaguchi with that of Lord so that the system can use the digital signal as an input to the microprocessor. As to Claim 14 is rejected using the same prior arts and reasoning as to that of claim 7. As to Claim 15 is rejected using the same prior arts and reasoning as to that of claim 8.
