Office Action

§103
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 Claims 1-15 are currently pending and are subject to this office action. Claim 15 is newly added. This office action is in response to Applicant’s arguments and remarks filed on 01/15/2026. Response to Amendments Examiner acknowledges Applicant’s response filed on 01/15/2026 containing amendments and remarks to the specification and drawings. In response to Applicant’s amendments filed 01/15/2026 , the Examiner withdraws the objection to the drawings for missing reference characters. In response to Applicant’s amendments filed 01/15/2026 , the Examiner withdraws the objection to the specification for minor informalities. Response to Arguments Applicant’s arguments, on pages 7-10, filed 01/15/2026, with respect to the rejection of claim 1 under 35 U.S.C. 103 have been fully considered and are persuasive. The Applicant argues that since Liu does not teach wherein an aerosol generation chamber receives a substrate, Liu cannot teach or suggest an exertion force applied on a substrate. The Examiner agrees. The previous rejection of Claim 1 referenced the atomization assembly of Liu as the aerosol generation chamber and substrate of the claimed invention which is not possible. Since the atomization assembly of Liu cannot be referenced as the substrate, Liu cannot teach or suggest an exertion force applied on the substrate. The following are modified rejections based on Applicant’s arguments and remarks 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, 6, 7, 12, and 14 are rejected under 35 U.S.C. 103 as being unpatentable over Liu (US 20200323263 A1). PNG media_image1.png 611 425 media_image1.png Greyscale PNG media_image2.png 714 317 media_image2.png Greyscale With regard to Claim 1, Liu, directed to an electronic cigarette, teaches (i) a groove (Fig. 25: "A", [0099]), meeting the claim limitation of an aerosol generation chamber, that receives a cartridge (Fig. 35: #21) and is heated by an atomization assembly (Fig. 35: #2) within the space, to generate smoke [0002]. (ii) A top cover (Fig. 25: #24) can be opened and closed to expose and replace the cartridge (Fig. 35: #21) within the aerosol generation chamber (Fig. 25: "A", [0100]). (iii) The device comprises a sliding column (Fig. 25: #6), unlocking mechanism (Fig. 25: #4), and elastic mechanism (Fig. 25: #5) comprising several assisting components for ejection and replacement of the cartridge [0085-0088], meeting the claim limitation of an ejection mechanism. The sliding column (Fig. 25: #6) indirectly controls the movement of the top cover (Fig. 25: #24, [0100]) and allows for the cartridge (Fig. 35: #21) to be ejected for replacement upon ejection of the atomization assembly (Fig. 35: #2, [0135]), while the top cover (Fig. 25: #24) is open [0100], and secured while the top cover (Fig. 25: #24) is locked [0124]. (iv) When the atomization assembly (Fig. 35: #2) is ejected, the top cover (Fig. 25: #24) is opened. One of ordinary skill in the art would understand that since the cartridge (Fig. 35: #21) sits on the atomization assembly and the atomization assembly can be formed whole with the cartridge [0029], when the atomization assembly is ejected [0086], the cartridge is also ejected and exposed [0100]. The groove (Fig. 25: "A") is disposed at the top of the sliding column (Fig. 25: #6) which receives the cartridge (Fig. 35: #21, [0099]) and the sliding column (Fig. 25: #6) can lock the cartridge in position [0115]. (v) In the next state, the top cover (Fig. 25: #24) is opened while the cartridge is exposed [0100]. The sliding column (Fig. 25: #6) holds the cartridge (Fig. 35: #21) in the groove (Fig. 25: "A") at the top of the sliding column [0099] and can be fixed and locked reliably [0115-0116]. The sliding column (Fig. 25: #6) transitions towards the next position when the top cover (Fig. 25: #24) is moved to the closed position and locked [0115-0116]. A spring (Fig. 25: #13) and ejector rod (Fig. 25: #10) lift the atomization assembly (Fig. 35: #2), which supports the cartridge (Fig. 35: #21, [0029]), and exerts an ejection force on the atomization assembly (Fig. 35: #2) and cartridge (Fig. 35: #21, [0089]). PNG media_image1.png 611 425 media_image1.png Greyscale PNG media_image3.png 643 378 media_image3.png Greyscale With regard to Claim 2, Liu teaches wherein (i) the groove (Fig. 25: "A") comprises an opening at the top to receive the cartridge [0099]. (ii) A top column (Fig. 31: #14) of the ejection mechanism is formed at the bottom of the groove (Fig. 35: "A") and protrudes into the groove at the top of the sliding column (Fig. 25: #6, [0135]). With regard to Claim 3, Liu teaches wherein (i) a cartridge is inserted in the groove (Fig. 35: "A"). (ii) The sliding column (Fig. 25: #6) is also pressed down upon insertion of the cartridge (Fig. 31: #21) and can push down the top column (Fig. 31: #14). One of ordinary skill in the art would understand that since the atomization assembly (Fig. 25: #2) and the cartridge (Fig. 31: #21) can be made as a whole [0012], the bottom of the atomization assembly (Fig. 25: #2) pressing down vertically into the top column (Fig. 31: #14, [0134), would also apply to the cartridge (Fig. 31: #21) upon insertion. With regard to Claim 4, Liu teaches wherein the sliding column (Fig. 31: #6) comprises a slider (Fig. 25: #7, [0089]), meeting the claim limitation of a snap member, which is configured to fix the sliding column (Fig. 31: #6), thereby holding the cartridge (Fig. 31: #21) in a position within the groove (Fig. 25: "A"). PNG media_image4.png 611 425 media_image4.png Greyscale With regard to Claim 5, Liu teaches wherein the elastic mechanism (Fig. 25: #5) comprises a fourth spring (Fig. 25: #13) configured to exert an upward force to an ejector rod (Fig. 25: #10), affecting the position of the rotating tongue (Fig. 25: #8, [0135]). With regard to Claim 6, Liu teaches a rotating tongue (Fig. 25: #8), meeting the claim limitation of a support member, comprising an upper arm (Fig. 25: "UA") which supports the bottom of the slider (Fig. 25: #7) of the sliding column (Fig. 25: #6) through a rotating tongue (Fig. 25: #8). The upper arm (Fig. 25: “UA”) is supported by abutting of the ejector rod (Fig. 25: #10) based on movement from the fourth spring (Fig. 25: #13, [0135]). PNG media_image4.png 611 425 media_image4.png Greyscale PNG media_image5.png 635 390 media_image5.png Greyscale With regard to Claim 7, Liu teaches (i) wherein the upper arm (Fig. 25: "UA") of the rotating tongue (Fig. 25: #8) comprises a protruding member (Fig. 25: "P"), which meets the slider (Fig. 25: #7) and controls the movement of the buckling portion (Fig. 33: #701), meeting the claim limitation of a protrusion of the snap member. (ii) The buckling portion (Fig. 33: #701) is configured to drive the slider (Fig. 25: #7) of the sliding column (Fig. 25: #6) forward or backward by extending the buckling portion into a buckling groove (Fig. 33: #20) of the cartridge for exertion [0137]. PNG media_image6.png 512 442 media_image6.png Greyscale PNG media_image7.png 672 436 media_image7.png Greyscale PNG media_image8.png 278 279 media_image8.png Greyscale With regard to Claim 12, Liu teaches (i) a limiting portion (Fig. 11: #606) that can limit the movement of the top cover (Fig. 11: #24) and abuts against the top cover when it is not opened (Fig. 11: #24, [0099]. (ii) One of ordinary skill in the art would understand that if the top cover is not removed, the cartridge cannot be fully ejected, despite efforts from the ejector rod to eject it. (iii) A hook (Fig. 1: #6061) is provided on the limiting portion (Fig. 11: #606) and aligns with a clamping slot (Fig. 4: #2402) of the top cover (Fig. 11: #24) to produce a locking effect [0115]. One of ordinary skill in the art would find it obvious to substitute the hook and clamping slot of Liu with a known alternative, such as magnets or snap fasteners, as they are well-known in the arts and is a simple alternative yielding the same result of securing the cover of the device. PNG media_image2.png 714 317 media_image2.png Greyscale With regard to Claim 14, Liu teaches wherein the cartridge (Fig. 21: #2) is a 3D shaped cube. Although it’s not specified if the cartridge is flat, one of ordinary skill in the art would know that changing the shape of the cartridge of Liu is simply a difference in design choice and would not change the function and purpose of the component (MPEP 2144.04.IV). Claims 8 and 9 are rejected under 35 U.S.C. 103 as being unpatentable over Liu (US 20200323263 A1), as applied to claims 1, 4, and 7, and further in view of Batista (WO 2020148334 A1). PNG media_image4.png 611 425 media_image4.png Greyscale PNG media_image5.png 635 390 media_image5.png Greyscale With regard to Claim 8, Liu teaches (i) wherein the buckling portion (Fig. 33: #701) protrudes through an opening provided for the cartridge to be inserted and the top cover (Fig. 21: #24) is slid to the right. (ii) When the buckling portion (Fig. 33: #701) is pushed in, prompted by the receival of the cartridge, the fourth spring (Fig. 25: #13) abuts the rotating tongue (Fig. 25: #8, [0134-0135]). Modified Liu teaches all the limitations of the claims as set forth above, however modified Liu is silent to: Wherein the snap member protrudes above the opening Wherein the snap member is configured to be pressed down by the cover Batista, directed to an aerosol generating device, teaches (i) where the aerosol generating device comprises a protruding element, which can be accessed by a user to change the position of a top cover (Pg 6, Lines 3-4). One of ordinary skill in the art would realize that since the protruding element moves in a direction parallel to the longitudinal axis of the device (Pg. 5, Line 34-35) and is accessible by a user, the protruding element must be above an opening of the device. (ii) The protruding element can be pushed down by a top cover to operate locking means of the device (Pg. 6, Lines 11-12) to enhance the comfort for the user to change the position of the top cover (Pg. 6, Line 4-5). 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 snap member of modified Liu to wherein snap member protrudes above the opening and is configured to be pressed down by the cover because both Liu and Batista are directed to improving user experience with removable components of an aerosol generation device. Batista teaches a protruding element that moves in a direction parallel to the longitudinal axis of the device, by being pressed down by a cover, to enhance the comfort for the user to change the position of the top cover (Pg. 6, Line 4-5) and this merely involves combining the locking means of Liu and Batista according to known removable methods to yield predictable results. PNG media_image9.png 408 311 media_image9.png Greyscale PNG media_image4.png 611 425 media_image4.png Greyscale With regard to Claim 9, Liu teaches (i) wherein the slider (Fig. 25: #7) comprises an upper (Fig. 5: "U") and lower part (Fig. 5: "L") that moves in response to the spring (Fig. 5: #11, [0134]). (ii) The upper part (Fig. 5: "U") of the slider (Fig. 5: #7) protrudes through an opening provided for the cartridge to be inserted and the top cover (Fig. 25: #24) is slid to the right. (ii) The lower part (Fig. 5: "L") is connected to the part of the slider (Fig. 25: #7) that protrudes into the opening. Modified Liu teaches all the limitations of the claims as set forth above, however modified Liu is silent to: Wherein the upper portion is configured to protrude above the opening when the cover is in the open position Batista, directed to an aerosol generating device, teaches (i) where the aerosol generating device comprises a protruding element, which can be accessed by a user to change the position of a top cover (Pg 6, Lines 3-4). One of ordinary skill in the art would realize that since the protruding element moves in a direction parallel to the longitudinal axis of the device (Pg. 5, Line 34-35) and is accessible by a user, an upper portion of the protruding element must be above an opening of the device, while a lower portion of the protruding element remains in the device. 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 snap member of modified Liu to wherein the upper portion is configured to protrude above the opening when the cover is in the open position because both Liu and Batista are directed to improving user experience with removable components of an aerosol generation device. Batista teaches a protruding element that moves in a direction parallel to the longitudinal axis of the device, by being pressed down by a cover, to enhance the comfort for the user to change the position of the top cover (Pg. 6, Line 4-5) and this merely involves combining the locking means of Liu and Batista according to known removable methods to yield predictable results. Claims 10 and 11 are rejected under 35 U.S.C. 103 as being unpatentable over Liu (US 20200323263 A1 and Batista (WO 2020148334 A1), as applied to claims 1, 2, 4, 5, 6, 7, and 9, and further in view of Adair (WO 2020182695 A1) PNG media_image10.png 408 311 media_image10.png Greyscale PNG media_image11.png 657 363 media_image11.png Greyscale PNG media_image12.png 663 372 media_image12.png Greyscale With regard to Claim 10, Liu teaches wherein (i) the upper portion (Fig. 5: "U") and the lower portion (Fig. 5: "L") of the buckling portion (Fig. 5: #701) slide relative to the first plane (Fig. 5: #6011) and second plane (Fig. 5: #702). (ii) When the upper portion (Fig. 5: "U") is pushed back, the lower portion (Fig. 5: "L") is also slid back along a horizontal axis relative to the device until the protrusion (Fig. 22 & 23: “P”) contacts the other side of the groove in the lower portion (Fig. 5: "L"), as shown by the circles in Figures 22 and 23, when the cartridge is inserted and the top cover is on the left. (iii) The protrusion of the rotating tongue ( Fig. 22 & 23: “P”) contacts a groove of the slider (Fig. 5: #7) comprising the buckling portion (Fig. 5: #701) and slides backward in a horizontal direction upon the insertion of the cartridge. Modified Liu teaches all the limitations of the claims as set forth above, however modified Liu is silent to: The protrusion of the arm is partially engaged with the protrusion of the snap member in a sliding manner PNG media_image13.png 422 335 media_image13.png Greyscale Adair, directed to an electronic cigarette, teaches first and second protrusions (Fig. 5: #32 & #33). During cartridge insertion, the first protrusions (Fig. 5: #32) directly contact and slide relative to the second protrusions (Fig. 5: #33), to form a sliding engagement (Pg. 6, Lines 5-13). One of ordinary skill in the art would have found it obvious to combine the protrusion engagement of Adair with the protrusions of Liu to allow for a smooth insertion of the cartridge and reduce the risk of wear and tear (Pg. 6, Lines 18-22). 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 protrusions of modified Liu to wherein the protrusion of the arm is partially engaged with the protrusion of the snap member in a sliding manner because both Liu and Adair are directed to improving cartridge insertion and security. Adair teaches two protrusions that form a sliding engagement to allow for a smooth insertion of the cartridge and reduce the risk of wear and tear (Pg. 6, Lines 18-22) and this merely involves combining prior art elements according to known secure insertion techniques ready for improvement to yield predictable results. PNG media_image10.png 408 311 media_image10.png Greyscale PNG media_image4.png 611 425 media_image4.png Greyscale With regard to Claim 11, Liu teaches wherein the repeatedly upper arm (Fig. 25: “UA”) cooperates with the lower portion of the slider (Fig. 5: “L”) to fix to a buckling groove (Fig. 5: #20, [0088-0089 & 0098]) during insertion and removal of the cartridge [0137]. One of ordinary skill in the art would have found it obvious to form the lower portion and arm from metal material because they repeatedly engage and slide against each other, being subject to mechanical stress and wear during use. This merely involves selecting a known material based on its suitability for its intended purpose and is considered prima facie obvious (MPEP 2144.07). Claim 13 is rejected under 35 U.S.C. 103 as being unpatentable over Liu (US 20200323263 A1), as applied to claim 1 and further in view of Fei (US 20200029622 A1) With regard to Claim 13, modified Liu teaches all the limitations of the claims as set forth above, however modified Liu is silent to: Wherein the cover is rotationally hinged on the main body of the aerosol generation device. Fei, directed to a portable vaporizer, teaches a lid configured to be connected to a body using a hinge, allowing the lid to rotate away from the body [0017]. One of ordinary skill in the art would have found it obvious to modify the cover of modified Liu to allow it to be rotationally hinged on the main body to offer an alternative way of exposing the inside of the housing when the latch for the lid is released to replace a cartridge [0022]. 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 cover of modified Liu to wherein the cover is rotationally hinged on the main body of the aerosol generation device because both Liu and Fei are directed to removable lids for replacing components of an aerosol generating device. Fei teaches a lid with a hinge that rotates away from a device body to expose the inside of the housing when the latch for the lid is released to replace a cartridge [0022] and this merely involves applying a known way of removable to a lid of a known aerosol generating device ready for improvement to yield predictable results. Claim 15 is rejected under 35 U.S.C. 103 as being unpatentable over Liu (US 20200323263 A1), as applied to claim 1 above, and further in view of DeMerritt (US 20160192708 A1). With regard to Claim 15, modified Liu teaches all the limitations of the claims as set forth above, however modified Liu is silent to: Wherein the substrate is porous DeMerritt, directed to an enhanced electronic cigarette, teaches a porous cartridge containing a functional liquid [0092] to improve fluid distribution and retention [0092 & 0093]. 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 substrate of Liu to be porous because both Liu and DeMerritt are directed to reducing the risk of liquid waste in aerosol generating devices. DeMerritt teaches a porous cartridge to improve fluid distribution and retention [0092 & 0093] and this merely involves applying a known material to a known cartridge of an aerosol generating device ready for improvement to yield predictable results.
