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 . Election/Restrictions Applicant’s election of Group I, claims 1-9 for examination, without traverse in the reply filed on December 19, 2025 is acknowledged. 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 of this title, 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 set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied 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 1-8 are rejected under 35 U.S.C. 103 as being unpatentable over Janardhan (US 2019/0295304 A1, hereinafter referenced “Jan”) in view of Kobal (US 2017/0196260 A1, hereinafter referenced “Kobal”). In regards to claim 1. (original): Jan discloses a method of controlling an electronic device (Jan, Abstract), the method comprising: -predicting a virtual smoke implementation timepoint Jan, para [0101] and [0144]; Reference at [0101] discloses moreover, due to various restraints (e.g., battery life, processing power, memory constraints, display screen resolutions, heat generation issues, etc.) related to the use of the simulation device 300 with regards to system 100, particularly in regards to the real-time collection of data regarding the drawing and ejection operation by the adult vaper, the real-time processing of the 3D vapor simulation and the particle generation, and the real-time AR simulation and VR simulation, the visual quality of the AR simulation and/or the VR simulation of the system 100 may be improved upon. Para [0144] discloses once paired, in operation S501, the simulation device 300 receives and/or detects drawing information corresponding to the adult vaper's operation of the e-vaping device 200. For example, the e-vaping device 200 may transmit information related to the operation of the e-vaping device 200 by the adult vaper, such as the start time of a drawing of vapor from the e-vaping device 200, the stop time of a drawing of vapor from the e-vaping device 200, the amount of pressure exhibited by the drawing operation, the volume of vapor flow, etc. Analyzing start and stop timing of drawing of vapor for the simulation device 300 for subsequent AR/VR simulation interpreted as predicting a virtual smoke implementation timepoint via monitoring vapor exhalation characteristics of the adult user); -and transmitting a control signal comprising the virtual smoke implementation timepoint to a device for displaying a virtual image (Jan, Fig. 5 and para [0168]; Reference discloses next, in operation S508, the 3D vapor simulator 321 provides and/or transmits the generated 3D vapor particle model to the AR simulator 323 and/or the VR simulator 324 based on the operation mode and/or hardware capabilities of the simulation device 300 for display by the simulation device 300…In other words, using AR glasses as an example, the AR glasses may provide a clear unobstructed view of the adult vaper's present environment (e.g., the room or other physical space that the adult vaper is occupying). The generated 3D vapor particle model is then overlaid and/or projected onto the adult vaper's environment using the AR glasses as a 2D or 3D image on the AR glasses in real-time, with real-time and/or static modeling of the generated vapor particles and/or generated ejected vapor cloud. Transmitting 3D vapor model to AR/VR simulators for display or the AR glasses interpreted as transmitting a control signal comprising the virtual smoke implementation timepoint to a device for displaying a virtual image ). Jan does not explicitly disclose but Kobal teaches -by monitoring a change value of a capacitance of the electronic device (Kobal, para [0032]-[0035]; Reference at [0032] discloses the exemplary cigarette model 300 preferably includes a sensor 340, which can be used to sense the position and motion of the model 300, as well as air flow direction and force within the model 300 (i.e. interpreted as monitoring a change value of a capacitance of the electronic device). For example, if a cigarette model 300 is placed in a smoker's mouth, the sensor 340 can be used to sense the position of the cigarette model 300, as well as the path of movement by which the smoker moved the cigarette model 300 and transmit signals indicative of same to a monitor. Para [0035] discloses It is noted that by providing a sensor 340 at a lit end of the cigarette model 300, as illustrated in FIG. 3, the movement of the lit end of the cigarette shaped model 300 can be closely monitored and tracked). Jan and Kobal are combinable because they are in the same field of endeavor regarding virtual smoking. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention for the AR/VR based e-vaping simulation system of Jan to include the VR smoking features of Kobal in order to provide the user with a system for generating augmented reality (AR) and/or virtual reality (VR) vapor simulation applications where vaping characteristics of vaping based on the audio signals are recorded to generate a vaping simulation based on the analyzed characteristics, and transmitting a simulation to a headset to be displayed on a display panel as taught by Jan, while incorporating the VR smoking features of Kobal to allow for use of a virtual smoking system in which the room environment may be simulated to give the experience of smoking in a setting of the smoker's choice allowing for the user to simulate the physical and sensorial pleasure of smoking without the burning of tobacco, applicable to improving the virtual smoking experience in systems such as those taught in Jan.

For example, if a cigarette model 300 is placed in a smoker's mouth, the sensor 340 can be used to sense the position of the cigarette model 300, as well as the path of movement by which the smoker moved the cigarette model 300 and transmit signals indicative of same to a monitor. Para [0035] discloses It is noted that by providing a sensor 340 at a lit end of the cigarette model 300, as illustrated in FIG. 3, the movement of the lit end of the cigarette shaped model 300 can be closely monitored and tracked) . Kobal does not explicitly disclose -first threshold (value) / second threshold (value) (However, the primary reference Jan previously discloses this concept in para [0122] which details the controller 45 performs features of the second section 72, as well as the entire e-vaping device 60, such as controlling the heater, interfacing with an external charger and monitoring the pressure within the e-vaping device 60 to determine whether an adult vaper has applied a negative pressure. Moreover, the controller 45 may determine whether an adult vaper has applied a positive pressure for a threshold time (i.e. the inhale/exhaling regarding the adult vaper interpreted as first and second timepoints having the corresponding thresholds).
