Response to Amendments Examiner acknowledges Applicant’s response filed on 11/19/2025 containing amendments and remarks to the claims. Response to Arguments Applicant’s arguments, on pages 8-11, filed 11/19/2025, with respect to the rejection of claim 1 under 35 U.S.C. 103 have been fully considered and are persuasive. The Applicant has amended claim 1 to include a limitation that was not previously presented, specifically, “a replaceable mouthpiece free of an aerosol-generating substrate”. However, upon further consideration, a new ground(s) of rejection is made in view of Twite (US 20210153565 A1). The following are modified rejections based on Applicant’s amendments to the claims. 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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claims 1, 2, 3, 4, 5, 7, 22, and 23 are rejected under 35 U.S.C. 103 as being unpatentable over Du (US 20220039465 A1), and further in view of Twite (US 20210153565 A1). PNG media_image1.png 729 349 media_image1.png Greyscale PNG media_image2.png 696 411 media_image2.png Greyscale With regard to Claim 1, Du, directed to an electronic cigarette, teaches (i) a vaporization device with a main body portion (Fig. 4a: #4) comprising a first cartridge seat (Fig. 4c: #12, [0053]), meeting the claim limitation of a capsule-receiving cavity. (ii) A mouthpiece (Fig. 4a: #6), relating to the lid of the claimed invention, is movably connected to the main body portion (Fig. 4a: #4) by a connection mechanism [0053] at a first and second point of the device (Fig. 4a: "FP" and "SP"). Du further teaches wherein (iii) the mouthpiece (Fig. 4a: #6) may be put in a closed position to enclose the received first cartridge (Fig. 4c: #16, [0053]) in a first cartridge seat (Fig. 4c: #12). (iii) The device includes a second cartridge (Fig. 4a: #46), couplable to the mouthpiece (Fig. 4a: #6), serving as a vapor outlet [0062]. Du teaches all of the limitations as set forth above, however Du is silent to: A replaceable mouthpiece free of an aerosol-generating substrate A first retainer A second retainer configured to engage with the first retainer so as to releasably secure the replaceable mouthpiece to the lid A ledge configured to position the replaceable mouthpiece with respect to the lid PNG media_image3.png 592 474 media_image3.png Greyscale Twite, directed to a non-nicotine e-vaping device, teaches teaches (i) wherein a mouthpiece (Fig. 13: #102) may be reversibly coupled to a retention structure of the device housing, wherein the mouthpiece does not comprise an aerosol generating substrate [0075].

Liu further teaches wherein (iv) when the two buttons (Fig. 10: #B41) are pressed, the locking legs break away from the limitations of the clamping grooves (Fig. 9: #A141) to open a liquid filling port [0039], meeting the claim limitation of wherein when the latch button is pressed, the latch button arm presses the receiving arm. One of ordinary skill in the art would find it obvious to combine this locking structure with the open and closing level mechanism of modified Du to meet the claim limitation of wherein the inner latching lever is moved such that the latching arm disengages form the lid latch to open the lid. (v) A spring (Fig. 10: #B412) is included on the button, which would be connected to the lever through the latch button arm, and abuts on the suction nozzle cover (Fig. 6: #B1) surrounding the e-liquid tank (Fig. 6: "A"), meeting the claim limitation of a spring connecting the inner latching lever to the external portion of the capsule receiving cavity Therefore, before the effective filing date of the claimed invention, it would have been obvious for one of ordinary skill in the art to modify the lid latch assembly of modified Liu to include a latch button with an arm extending from an inner surface of the button, a receiving arm configured to contact the latch button arm, wherein when the latch button is pressed, the latch button arm presses the receiving arm and moves the inner latching lever such that the latching arm disengages from the lid latch to open the lid, and spring connecting the inner latching lever and the external portion of the capsule-receiving cavity because both Du and Liu are directed to covering aerosol forming articles in aerosol generating device. Liu teaches a child lock structure comprising two buttons, with locking legs configured to make contact with clamping grooves and wherein the two buttons are pressed to ultimately open a liquid filling port to restrict child access and this merely involves applying a known locking mechanism to a similar aerosol generating device ready for improvement to yield predictable results. Claim 17 is rejected under 35 U.S.C. 103 as being unpatentable over Du (US 20220039465 A1), Twite (US 20210153565 A1), and Liu (US 20220151301 A1), as applied to claims 1 and 16 above, further in view of Michaud (US 20220175029 A1) With regard to Claim 17, modified Du teaches all of the limitations of the claims as set forth above, however modified Du is silent to: Wherein the lid latch assembly applies about 30 newtons of downward force on a capsule in the capsule-receiving cavity when the lid is in the closed position PNG media_image24.png 375 256 media_image24.png Greyscale Michaud, directed to a locking mechanism for a vaporizer cartridge, teaches wherein a subassembly tip (Fig. 1: #1) and a subassembly base (Fig. 1: #2) can be pressed together with a force less than 6 kg [0090], where in between both is a hollow cylinder (Fig. 1: #6), meant to contain a vape material [0057], received in a shield (Fig. 1: #8). One of ordinary skill in the art would find it obvious that the conversion of 6 kg to Newtons is 58.68 N. Less than 58.68 N as said by Michaud, overlaps with the measurement of 30 Newtons in the claimed invention and is therefore considered prima facie obvious. Therefore, before the effective filing date of the claimed invention, it would have been obvious for one of ordinary skill in the art to modify the lid latch assembly of modified Du to apply about 30 Newtons of downward force on a capsule in the capsule-receiving cavity when the lid is in the closed position because both Du and Michaud are directed to sealing mechanism of cartridges. Michaud teaches wherein a subassembly tip and a subassembly base can be pressed together with a force of less than 6 kg to allow easy filling and assembly of vape cartridges [0053] and this merely involves applying a known measurement of force to a similar locking mechanism in an aerosol generating device ready for improvement to yield predictable results. Claims 18 and 19 are rejected under 35 U.S.C. 103 as being unpatentable over Du (US 20220039465 A1), Twite (US 20210153565 A1), and Qui (US 20210315281 A1), as applied to claims 1 and 10 above, further in view of Shu (CN 113424988 A, hereinafter citations referring to English Machin Translation) With regard to Claim 18, modified Du teaches all the limitations of the claims as set forth above, however modified Du is silent to: A charging connector defined within the housing, the at least one air inlet surrounding charging connector PNG media_image25.png 650 256 media_image25.png Greyscale Shu, directed to an anti-tar-leakage electronic cigarette, teaches a charging socket (Fig. 2: #15) that is embedded with an air inlet (Fig. 2: #14), meeting the claim limitation of a charging connector defined within the housing, the at least one air inlet surrounding charging connector Therefore, before the effective filing date of the claimed invention, it would have been obvious for one of ordinary skill in the art to modify the housing of modified Du to include a charging connector, wherein the at least one air inlet surrounds the charging connector because both Du and are directed to directed to aerosol generating devices with cartridges to generate aerosol. Shu teaches a charging socket embedded with an air inlet to charge a battery to supply power to a heating element [n0011] and this merely involves the use of a known charging port feature to improve a similar aerosol generating device in the same way. With regard to Claim 19, modified Du teaches all the limitations of the claims as set forth above, however modified Du is silent to: A grill surrounding the charging connector The grill defining at least one air inlet PNG media_image26.png 650 256 media_image26.png Greyscale Shu teaches (i) a charging socket (Fig. 2: #15) surrounded by a frame (Fig. 2: "F"), meeting the claim limitation of a grill surrounding the charging connector. (ii) The frame defines the boundary of the air inlet formed by an air inlet gap between the charging socket (Fig. 2: #12) and the side wall of the air inlet (Fig. 2: #14), meeting the claim limitation of the grill defining at least one air inlet. Therefore, before the effective filing date of the claimed invention, it would have been obvious for one of ordinary skill in the art to modify the charging connector of modified Du grill surrounding the charging connected and the grill defining at least one air inlet because both Du and are directed to directed to aerosol generating devices with cartridges to generate aerosol. Shu teaches a charging socket surrounded by a frame defining the boundary of an air inlet to create an entrance for a plug to effectively charge a battery to supply power to a heating element [n0011] and this merely involves the use of a known surrounding grill with a charging connector to improve a similar aerosol generating device in the same way. Claim 21 is rejected under 35 U.S.C. 103 as being unpatentable over Du (US 20220039465 A1), Twite (US 20210153565 A1), and Claude (WO 2021240397 A1), as applied to claims 1 and 20 above, and further in view of Capelli (US 20220225668 A1). With regard to Claim 21, modified Du teaches all of the limitations of the claims as set forth above, however, modified Du is silent to: Wherein the second end of the capsule-receiving cavity includes one or more alignment members configured to guide a capsule received by the capsule-receiving cavity, the one or more alignment members having a rib shape PNG media_image27.png 517 279 media_image27.png Greyscale Capelli, directed to an aerosol-generating device, teaches wherein an extractor (Fig. 11: #100) with a cavity (Fig. 11: #710) for containing an aerosol-generating article [0105]. The bottom of the extractor (Fig. 11: #100) may comprise one or more ribs (Fig. 11: #790) to help guide and stabilize an aerosol-generating article inserted in the cavity [0040], meeting the claim limitation of wherein the second end of the capsule-receiving cavity includes one or more alignment members configured to guide a capsule received by the capsule-receiving cavity, the one or more alignment members having a rib shape. Therefore, before the effective filing date of the claimed invention, it would have been obvious for one of ordinary skill in the art to modify the capsule-receiving cavity of modified Du to include one or more alignment members at its second end to guide a capsule received by the capsule-receiving cavity, the one or more alignment members having a rib shape, because both Du and Capelli are directed to aerosol-generating devices comprising cavities with protruding aerosol generating material. Capelli teaches wherein a bottom of an extractor comprises one or more ribs to help guide and stabilize an aerosol-generating article inserted in the cavity and this merely involves the use of a known guiding feature to improve a similar aerosol generating device in the same way. Claim 24 is rejected under 35 U.S.C. 103 as being unpatentable over Du (US 20220039465 A1) and Twite (US 20210153565 A1), as applied to claims 1 and 3 above, further in view of Villamar (US 20210289842 A1). PNG media_image1.png 729 349 media_image1.png Greyscale PNG media_image28.png 386 219 media_image28.png Greyscale With regard to Claim 24, Du teaches wherein (i) the second cartridge (Fig. 4a: #46) is inserted through an opening of the mouthpiece portion (Fig. 4a: #6). (ii) The opening of the mouthpiece portion (Fig. 4a: #6), relating to the lid of the claimed invention, comprises an extended portion (Fig. 7: "E") at the bottom of the second cartridge seating (Fig. 7: #42). Modified Du teaches all the limitations of the claims as set forth above, however modified Du is silent to: The opening of the lid configured to be secured to the second mouthpiece end PNG media_image29.png 398 389 media_image29.png Greyscale PNG media_image30.png 451 434 media_image30.png Greyscale Villamar, directed to a ceramic vaporizer, teaches a mouthpiece (Fig. 5: #120) that is removably coupled vid a lid (Fig. 5: #502, [0027]). Figure 4 illustrates wherein the mouthpiece (Fig. 4: #120) is inserted into a heating chamber (Fig. 4: #124). One of ordinary skill in the art would understand that the lid (Fig. 5: #502) is placed between the mouthpiece (Fig. 5: #120) and the heating chamber (Fig. 4: #124). Therefore, for the mouthpiece to reach the heating chamber, the mouthpiece must also be insertable through an opening of the lid. Since Villamar discloses that the lid aides in the coupling function of the mouthpiece [0027], it would have been obvious to one of ordinary skill in the art that the bottom end of the mouthpiece is secured by the opening of the lid. Therefore, before the effective filing date of the claimed invention, it would have been obvious for one of ordinary skill in the art to modify the lid of modified Du to wherein the opening of the lid configured to be secured to the second mouthpiece end because both Du and Villamar are directed to removable mouthpieces coupled via lids. Villamar teaches a mouthpiece removably coupled by a lid to help prevent material from entering the mouth of a user [0022] and this merely involves applying a known mouthpiece configuration to a known lid of an aerosol generating device ready for improvement to yield predictable results.
