Office Action

§103
DETAILED ACTION 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 1-4, 6-8, 10-14, are rejected under 35 U.S.C. 103 as being unpatentable over Bell (US 2023/0024525) in view of Cristian (US 2023/0292847). Regarding claim 1, Bell teaches an aerosol delivery device configured to engage with a component to form an aerosol delivery system, the device comprising: electrical circuitry arranged to control the supply of power to an aerosol generation unit and to detect engagement and disengagement of a component with the device [0043-0046], wherein the circuitry is configured to: in an unlocked state, control the supply of power to the aerosol generation unit to enable the generation of an aerosol if a user inhales through the system [0071]; in a locked state, control the supply of power to the aerosol generation unit to prevent the generation of an aerosol if a user inhales through the system [0070, 0072, 0146]; and transition the system from the locked state to the unlocked state in response to a detection of a predefined sequence of user actions, the predefined sequence of user actions comprising at least one disengagement of a component with the device and at least one engagement of a component with the device [0073-0076], wherein the circuitry is configured to control a visual feedback element to indicate the engagement state to the user [0080]. Bell does not teach indicating the predefined sequence to the user. Cristian teaches an aerosol delivery device wherein circuitry is configured to control a visual feedback element to indicate guidance signals for guiding the user to provide input [0014]. In the device of Bell, the predefined sequence is a user input mechanism [0074]. It would have been obvious to one of ordinary skill in the art to apply the concept of Cristian to the device of Bell such that the circuitry is configured to control a visual feedback element to indicate the predefined sequence to the user. One of ordinary skill in the art would have been motivated to guide the user to provide the input, i.e. the predefined sequence, as suggested by Bell. Regarding claim 2, Bell teaches the circuitry is configured to transition the system from the locked state to the unlocked state only if the predefined sequence of user actions is detected within a predetermined period of time [0095]. Regarding claim 3, Bell does not teach a memory operatively connected to the circuitry and configured to store the predefined sequence of user actions. Cristian teaches a memory operatively connected to the circuitry and configured to store software instructions [0046]. It would have been obvious to one of ordinary skill in the art to include in the device of Bell a memory operatively connected to the circuitry and configured to store software instructions, including the predefined sequence of user actions, for the benefit of storing operation instructions for the device. Regarding claim 4, Bell teaches the circuitry is configured to: detect a sequence of user engagements and disengagements of a component with the device; determine whether the detected sequence corresponds to the predefined sequence of user actions; and transition the system from the locked stated to the unlocked state if the detected sequence corresponds to the predefined sequence [0073]. Regarding claim 6, Bell teaches the circuitry is configured to control the visual feedback element to provide first visual feedback to the user upon the detection of the predefined sequence of user actions [0147]. Regarding claim 7, Bell teaches the circuitry is configured to control the visual feedback element to provide second visual feedback to the user upon detection of a sequence of user engagements and disengagements of a component with the device that does not correspond to the predefined sequence of user actions, wherein the second visual feedback is different from the first visual feedback [0098]. Regarding claim 8, Bell teaches the circuitry is configured to control the visual feedback element to output a sequence of visual flashes [0098]. In view of Cristiano as applied to claim 1 above, this would suggest to one of ordinary skill in the art that to provide a sequence of flashes that corresponds to the predefined sequence of user actions to indicate the predefined sequence to the user, so as to guide the user to provide the input. Regarding claim 10, Bell teaches the circuitry is configured to transition the system from an off state to the locked state if a user by pressing a button [0079]. As Bell discloses pressing a button and inhaling are alternatives for operation of the device [0128], this suggests to one of ordinary skill in the art that the circuitry may configured to transition the system from an off state to the locked state if a user inhales through the system when a component is engaged with the device to achieve predictable results. Regarding claim 11, Bell teaches the circuitry is configured to transition the system from the unlocked state to the locked state if a predetermined period of time has elapsed since a last user inhalation through the system [0123]. Regarding claim 12, Bell teaches an airflow sensor configured to detect a user inhalation [0039]. Regarding claim 13, modified Bell as applied to claim 1 above teaches an aerosol delivery device according to claim 1. Bell teaches the device is part of an aerosol delivery system comprising a consumable component for containing an aerosol precursor, the consumable component configured to be reversibly engageable with the aerosol delivery device to form the aerosol delivery system [0029-0030]. Regarding claim 14, Bell teaches the consumable component comprises the aerosol generation unit [0034]. Claim 9 is rejected under 35 U.S.C. 103 as being unpatentable over Bell and Cristian as applied to claim 1 above, and further in view of Anderson (US 2020/0000143). Modified Bell does not teach in the locked state, the circuitry is configured to control the visual feedback element to provide third visual feedback to the user if a user inhales through the system. However, this configuration is known in the art as taught by Anderson [0350] and would have been obvious to one of ordinary skill in the art to apply to the device of modified Bell for the purpose of indicating to the user that device will not work in the locked state.
