Num. 13) away from the first sealing member (Fig. 5, Ref. Num. 13), and the second sealing member (Fig. 5, Ref. Num. 17) is arranged in the second sealing groove. Regarding claim 9, Zhao teaches an airflow sensor (Fig. 5, Ref. Num. 21) arranged on the first mounting portion (Fig. 5, Ref. Num. 13) that is electrically connected to the circuit structure (Para. [0071]), and a position of the airflow sensor corresponds to a position of an air inlet (Fig. 5, Ref. Num. 9). Regarding claim 10, Zhao teaches an electrical connection member arranged between the airflow sensor and the circuit structure, a first end of the electrical connection member is electrically connected to an electrode of the airflow sensor, and a second end of the electrical connection member abuts against the circuit structure (Para. [0071]; Sensor is connected to the circuit). Regarding claim 12, Zhao teaches an e-cigarette (Fig. 4) comprising the power supply assembly of an aerosol-generation apparatus according to claim 1(See Claim 1 Rejection) and the vaporizer (Fig. 5, Ref. Num. 1) connected to the power supply assembly. Regarding claim 13, Zhao teaches a first sealing groove (Fig. 5, Ref. Num. 16) extending along a circumferential direction of the support provided between the first mounting portion (Fig. 5, Ref. Num. 13) and the second mounting portion (Fig. 4, Support inside housing, 12, that surrounds 4 and 5), and the first sealing member (Fig. 5, Ref. Num. 13) is arranged in the first sealing groove. Regarding claim 14, Zhao teaches that the first sealing member is an annular sealing ring (Para. [0063]) and the first sealing member is sleeved on the support (Fig. 5, Ref. Num. 16). Regarding claim 15, Zhao teaches that a mounting hole (Fig. 1, where the bottom of the electrode, 19, sticks through the first mounting portion, 13) is provided on the end of the first mounting portion (Fig. 5, Ref.

Num. 13) away from the first sealing member (Fig. 5, Ref. Num. 13), and the second sealing member (Fig. 5, Ref. Num. 17) is arranged in the second sealing groove. Regarding claim 20, Zhao teaches an airflow sensor (Fig. 5, Ref. Num. 21) arranged on the first mounting portion (Fig. 5, Ref. Num. 13) that is electrically connected to the circuit structure (Para. [0071]), and a position of the airflow sensor corresponds to a position of an air inlet (Fig. 5, Ref. Num. 9). 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. 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. Claims 6, 7, 17, and 18 are rejected under 35 U.S.C. 103 as being unpatentable over Zhao et al. (CN 112790436 A, with US 2023/0255266 as English Language Equivalent) as applied to claims 1 and 12 above, and further in view of Qiu et al. (US 2021/0401044 A1). Regarding claim 6, Zhao does not teach that the second sealing member is a cover structure. In an analogous art, Qiu teaches an e-cigarette with a second sealing structure (Fig. 9, 10 Ref. Num. 22) that is a cover structure. It would have been obvious to one of ordinary skill in the art before the effective filing date to modify Zhao with Qiu in order to form the second sealing member as a cover structure. This modification will create an accommodating cavity above the second sealing member to protect the heating member (Qiu; Para. [0170]). This second sealing member will cover the end of the first mounting portion (Zhao; Fig. 5, Ref. Num. 13; top) from the first sealing member (Fig. 5, Ref. Num. 18). Regarding claim 7, modified Zhao teaches that the electrode (Fig. 5, Ref. Num. 19) is electrically connected to the vaporizer (Para. [0054]) and since the electrode passes across the second sealing structure (Fig. 5, Ref. Num. 17), it must pass through an avoidance hole in the cover structure. Regarding claim 17, Zhao does not teach that the second sealing member is a cover structure. In an analogous art, Qiu teaches an e-cigarette with a second sealing structure (Fig. 9, 10 Ref. Num. 22) that is a cover structure. It would have been obvious to one of ordinary skill in the art before the effective filing date to modify Zhao with Qiu in order to form the second sealing member as a cover structure. This modification will create an accommodating cavity above the second sealing member to protect the heating member (Qiu; Para. [0170]). This second sealing member will cover the end of the first mounting portion (Zhao; Fig. 5, Ref. Num. 13; top) from the first sealing member (Fig. 5, Ref. Num. 18). Regarding claim 18, modified Zhao teaches that the electrode (Fig. 5, Ref. Num. 19) is electrically connected to the vaporizer (Para. [0054]) and since the electrode passes across the second sealing structure (Fig. 5, Ref. Num. 17), it must pass through an avoidance hole in the cover structure. Claims 8 and 19 are rejected under 35 U.S.C. 103 as being unpatentable over Zhao et al. (CN 112790436 A, with US 2023/0255266 as English Language Equivalent) as applied to claims 1 and 12 above, and further in view of Bowen et al. (US 2018/0093054 A1). Regarding claim 8, Zhao does not teach that the circuit is printed on to the support. In an analogous art, Bowen teaches circuits for e-cigarettes where the circuits are printed on to the support structure of the cigarette (Para. [0115]). It would have been obvious to one of ordinary skill in the art before the effective filing date to modify Zhao with Bowen to print the circuit structure on to the support. This modification will reduce the weight and fitting space (Bowen; Para [0115]). Regarding claim 19, Zhao does not teach that the circuit is printed on to the support. In an analogous art, Bowen teaches circuits for e-cigarettes where the circuits are printed on to the support structure of the cigarette (Para. [0115]). It would have been obvious to one of ordinary skill in the art before the effective filing date to modify Zhao with Bowen to print the circuit structure on to the support. This modification will reduce the weight and fitting space (Bowen; Para [0115]). Claim 11 is rejected under 35 U.S.C. 103 as being unpatentable over Zhao et al. (CN 112790436 A, with US 2023/0255266 as English Language Equivalent) as applied to claim 1 above, and further in view of Potter (US 2020/0288770 A1). Regarding claim 11, Zhao does not teach limiting convex strips. In an analogous art, Potter teaches an aerosol-generation apparatus (Fig. 2, Ref. Num. 100) that uses limiting convex strips (Fig. 6a, Ref. Num. 208c) and limiting grooves (Fig. 2, Ref. Num. 208d), where the convex strips are inserted into the limiting grooves, to connect different pieces of the aerosol-generating devices. It would have been obvious to one of ordinary skill in the art before the effective filing date to modify Zhao with Potter to used limiting convex strips and limiting grooves to connect the support and the housing. Theses grooves and strips are used to prevent leakage of aerosol and loss of pressure (Potter; Para. [0079]) and should have the same benefits connecting different parts of the aerosol-generating device together.
