DETAILED ACTION
Response to Arguments
Applicant’s arguments in view of amendment filed 7/8/2026with respect to the rejections of under 102 or 103 over Raichman have been fully considered and are persuasive. Therefore, the rejections have been withdrawn. However, upon further consideration, a new ground(s) of rejection is made as detailed below.
Claim Rejections - 35 USC § 103
The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action.
Claims 1-4, 9, 11-13, and 17 are rejected under 35 U.S.C. 103 as being unpatentable over Raichman (WO 2018/051346) in view of Gretton (US 2021/0337878).
Regarding claim 1, Raichman teaches an electronic vaping device comprising: a heating element that is to be energized to convert a portion of a medium into a vapor by elevating a temperature of the medium, wherein the medium comprises at least a first chemical constituent to be included in the vapor [page 16, l. 5-21]; an airflow passage through which air entraining the vapor flows as a result of a user inhaling through a mouthpiece during a puff [page 55, l. 13-16]; one or more sensors arranged to sense a parameter indicative of an airflow rate of the air entraining the vapor flowing through the airflow passage [page 3, l. 25 to page 4, l. 8]. Raichman teaches: in response to receiving an indication from the sensor that airflow rate through the vaporizing unit has increased, the control circuitry is configured to drive the heating element to increase a temperature of the plant material [page 10, l. 23-25]; increasing the temperature of the capsule causes an increase in the vaporization rate of the active ingredient, with more vapors being emitted as temperature is set higher [page 36, l. 7-10]; and when smoking a traditional combustion cigarette, an increase in the user's inhalation rate increases generated smoke, and in the vaping device the target temperature to which the capsule is heated is correlated to airflow rate (which is indicative of user inhalation rate), in order to simulate the burning of a traditional cigarette [page 39, l. 30 to page 40, l. 3]. Raichman further teaches the airflow rate is calculated based on the sensed parameter [col. 9, l. 14-26], which inherently involves some predetermined transfer function relating the sensed parameter to the airflow rate, and the controller controls operation of the heating element to simulate the behavior and increased generated smoke due to increased air flow rate of a standard combustion cigarette [page 5, l. 29 to page 6, l. 8]. In other words, Raichman teaches a controller that controls operation of the heating element based on the airflow rate of the air to control a concentration of the first chemical constituent based on the airflow rate calculated using a transfer function relating the sense parameter to the airflow rate, wherein the transfer function is predetermined so that the controlled concentration of the first chemical constituent mimics a type of cigarette.
Raichman does not specifically teach a plurality of user-selectable modes, each mode associated with a different type of cigarette and a different predetermined transfer function. Gretton teaches an electronic vaping system configured to receive from a user a selection of the type of cigarette they currently smoke, and the system then automatically adjusts parameters of the session so that the amount of nicotine generated by the vaping device, or inhaled by a user, during that session is approximately equivalent to the amount of nicotine associated with smoking a single cigarette of that specific type of cigarette [0386]. It would have been obvious to one of ordinary skill in the art to include with the device of Raichman a plurality of user-selectable modes, each mode associated with a different type of cigarette, to allow the user to correspond the amount of nicotine generated with the type of cigarette they smoke. As Raichman teaches the heating profile is adjusted to mimic a cigarette, one of ordinary skill in the art would appreciate that in modified Raichman, each mode should include a different heating profile and transfer function that relates the operation of the heating element to the sensed parameter and airflow rate, in order to provide different results for the different types of cigarettes.
Regarding claims 2-3, Raichman teaches the one or more sensors comprise a pressure sensor in fluid communication with the airflow passage, that senses a pressure of the air entraining the vapor [page 3, l. 25 to page 4, l. 8].
Regarding claim 9, it is interpreted that the controller controlling operation of the heating element based on the airflow rate of the air indicated by the sensed parameter necessarily results in interfering with dilution of the first chemical constituent as the airflow rate increases over a range of flow rates through the airflow passage, due to the increased concentration/yield of the constituent. Regarding the range of flow rates being up to 30 mL/sec, Raichman teaches the controller controls operation of the heating element to simulate the behavior and increased generated smoke due to increased air flow rate of a standard combustion cigarette [page 5, l. 29 to page 6, l. 8]. The instant invention discloses that this simulation of a standard combustion cigarette involves claimed range [instant specification 0063-0068]. Thus, modified Raichman is interpreted to read on the claimed range. In the alternative, Raichman teaches the controller controls operation of the heating element in accordance with a desired smoking profile desired by the user [page 8, l. 10-31]. It would have been obvious to one of ordinary skill in the art to optimize the smoking profile through routine experimentation to achieve the effects desired by the user.
Regarding claim 11, Raichman teaches an electronic vaping device comprising: a heating element that is to be energized to convert a portion of a medium into a vapor by elevating a temperature of the medium, wherein the medium comprises at least a first chemical constituent to be included in the vapor [page 16, l. 5-21]; an airflow passage through which air entraining the vapor flows as a result of a user inhaling through a mouthpiece during a puff [page 55, l. 13-16]; one or more sensors arranged to sense a parameter indicative of an airflow rate of the air entraining the vapor flowing through the airflow passage [page 3, l. 25 to page 4, l. 8]. Raichman teaches: in response to receiving an indication from the sensor that airflow rate through the vaporizing unit has increased, the control circuitry is configured to drive the heating element to increase a temperature of the plant material [page 10, l. 23-25]; increasing the temperature of the capsule causes an increase in the vaporization rate of the active ingredient, with more vapors being emitted as temperature is set higher [page 36, l. 7-10]; and when smoking a traditional combustion cigarette, an increase in the user's inhalation rate increases generated smoke, and in the vaping device the target temperature to which the capsule is heated is correlated to airflow rate (which is indicative of user inhalation rate), in order to simulate the burning of a traditional cigarette [page 39, l. 30 to page 40, l. 3]. Raichman further teaches the airflow rate is calculated based on the sensed parameter [col. 9, l. 14-26], which inherently involves some predetermined transfer function relating the sensed parameter to the airflow rate, and the controller controls operation of the heating element to simulate the behavior and increased generated smoke due to increased air flow rate of a standard combustion cigarette [page 5, l. 29 to page 6, l. 8]. In other words, Raichman teaches a controller that controls operation of the heating element based on the airflow rate of the air to control a concentration of the first chemical constituent based on the airflow rate calculated using a transfer function relating the sense parameter to the airflow rate, wherein the transfer function is predetermined so that the controlled concentration of the first chemical constituent mimics a type of cigarette, and increasing a yield of the first chemical constituent in the vapor entrained in the air as a result of an increase in the airflow rate over a range of flow rates of the air flowing through the airflow passage.
Regarding the range of flow rates being up to 30 mL/sec, Raichman teaches the controller controls operation of the heating element to simulate the behavior and increased generated smoke due to increased air flow rate of a standard combustion cigarette [page 5, l. 29 to page 6, l. 8]. The instant invention discloses that this simulation of a standard combustion cigarette involves claimed range [instant specification 0063-0068]. Thus, Raichman is interpreted to read on the claimed range. In the alternative, Raichman teaches the controller controls operation of the heating element in accordance with a desired smoking profile desired by the user [page 8, l. 10-31]. It would have been obvious to one of ordinary skill in the art to optimize the smoking profile through routine experimentation to achieve the effects desired by the user.
Raichman does not specifically teach a plurality of user-selectable modes, each mode associated with a different type of cigarette and a different predetermined transfer function. Gretton teaches an electronic vaping system configured to receive from a user a selection of the type of cigarette they currently smoke, and the system then automatically adjusts parameters of the session so that the amount of nicotine generated by the vaping device, or inhaled by a user, during that session is approximately equivalent to the amount of nicotine associated with smoking a single cigarette of that specific type of cigarette [0386]. It would have been obvious to one of ordinary skill in the art to include with the device of Raichman a plurality of user-selectable modes, each mode associated with a different type of cigarette, to allow the user to correspond the amount of nicotine generated with the type of cigarette they smoke.

Regarding claims 4 and 13, Raichman teaches the controller controls operation of the heating element to simulate the behavior and increased generated smoke due to increased air flow rate of a standard combustion cigarette [page 5, l. 29 to page 6, l. 8]. The instant invention discloses that this simulation of a standard combustion cigarette involves the controller controlling operation of the heating element to continuously increase a rate at which the first chemical constituent is converted into the vapor over the relatively-low range of the flow rates of the air flowing through the airflow passage [instant Fig. 9; instant specification 0063]. Thus, the controller of Raichman is interpreted to control operation of the heating element to continuously increase a rate at which the first chemical constituent is converted into the vapor over a range of flow rates of the air flowing through the airflow passage. In the alternative, Raichman teaches the controller controls operation of the heating element in accordance with a desired smoking profile desired by the user [page 8, l. 10-31]. It would have been obvious to one of ordinary skill in the art to optimize the smoking profile through routine experimentation, including the rate at which the first chemical constituent is converted into the vapor, to achieve the effects desired by the user.
Regarding claim 12, Raichman teaches the one or more sensors comprise a pressure sensor in fluid communication with the airflow passage, that senses a pressure of the air entraining the vapor [page 3, l. 25 to page 4, l. 8].
Regarding claim 17, it is interpreted that the controller controlling operation of the heating element based on the airflow rate of the air indicated by the sensed parameter necessarily results in interfering with dilution of the first chemical constituent as the airflow rate increases over a range of flow rates through the airflow passage, due to the increased concentration/yield of the constituent. Raichman thereby reads on the present limitations.
Claims 5-7, 10, 14-15, and 18 are rejected under 35 U.S.C. 103 as being unpatentable over Raichman and Gretton as applied to claim 1 and 11 above, and further in view of Novak (US 2020/0154786).
Regarding claims 5-7, Raichman does not teach a non-transitory computer-readable medium. Novak teaches a vaporization device including a non-transitory computer-readable medium for storing control profiles and instructions [0082]. As Raichman teaches controlling the generation of vapor in accordance with the airflow rate [page 39, l. 30 to page 40, l. 3], it would have been obvious to one of ordinary skill in the art to include in the device of Raichman a non-transitory computer-readable medium storing a profile reduceable to concentration that relates a resultant concentration of the first chemical constituent to each of a plurality of different flow rates of the air for memory storage purposes and for providing instructions to the controller for operation.
Regarding the claimed slope, Raichman teaches the controller controls operation of the heating element to simulate the behavior and increased generated smoke due to increased air flow rate of a standard combustion cigarette [page 5, l. 29 to page 6, l. 8]. The instant invention discloses that this simulation of a standard combustion cigarette involves claimed slopes [instant specification 0063-0068]. Thus, the profile and relationship stored in modified Raichman are interpreted to correspond to the claimed values. In the alternative, Raichman teaches the controller controls operation of the heating element in accordance with a desired smoking profile desired by the user [page 8, l. 10-31]. It would have been obvious to one of ordinary skill in the art to optimize the smoking profile through routine experimentation to achieve the effects desired by the user.
As a further alternative, the claims do not directly relate the profile stored on the non-transitory computer-readable medium to any configuration of the electronic vaping device. Therefore, any non-transitory computer-readable medium, including that of modified Raichman, is interpreted as capable of storing any profile or relationship such that it reads on the present limitations.
Regarding claims 10 and 18, Raichman teaches the controller controls operation of the heating element to simulate the behavior and increased generated smoke due to increased air flow rate of a combustion cigarette [page 5, l. 29 to page 6, l. 8]. Raichman does not teach a computer-readable medium. Novak teaches a vaporization device including a computer-readable medium for storing control profiles and instructions [0082]. It would have been obvious to one of ordinary skill in the art to modify the device of Raichman such that the controller comprises a computer-readable medium storing a model relating operation of the heating element based on the airflow rate to a concentration curve of a specific tobacco combustion cigarette to be simulated by the electronic vaping device for memory storage purposes and for providing instructions to the controller for operation.
Regarding claims 14-15, Raichman does not teach a non-transitory computer-readable medium. Novak teaches a vaporization device including a non-transitory computer-readable medium for storing control profiles and instructions [0082]. As Raichman teaches controlling the generation of vapor in accordance with the airflow rate [page 39, l. 30 to page 40, l. 3], it would have been obvious to one of ordinary skill in the art to include in the device of Raichman a non-transitory computer-readable medium storing a profile reduceable to yield that relates a resultant yield of the first chemical constituent to each of a plurality of different values of the airflow rates for memory storage purposes and for providing instructions to the controller for operation.
Regarding the claimed slope, Raichman teaches the controller controls operation of the heating element to simulate the behavior and increased generated smoke due to increased air flow rate of a standard combustion cigarette [page 5, l. 29 to page 6, l. 8]. The instant invention discloses that this simulation of a standard combustion cigarette involves claimed slopes [instant specification 0063-0068]. Thus, the profile and relationship stored in modified Raichman are interpreted to correspond to the claimed values. In the alternative, Raichman teaches the controller controls operation of the heating element in accordance with a desired smoking profile desired by the user [page 8, l. 10-31]. It would have been obvious to one of ordinary skill in the art to optimize the smoking profile through routine experimentation to achieve the effects desired by the user.
As a further alternative, the claims do not directly relate the profile stored on the non-transitory computer-readable medium to any configuration of the electronic vaping device. Therefore, any non-transitory computer-readable medium, including that of modified Raichman, is interpreted as capable of storing any profile or relationship such that it reads on the present limitations.
Claims 8 and 16 are rejected under 35 U.S.C. 103 as being unpatentable over Raichman and Gretton as applied to claims 1 and 11 above, and further in view of Gill (US 2017/0156403).
Raichman does not teach the controller controls operation of the heating element based on the airflow rate of the air indicated by the sensed parameter, at least maintaining a temperature of the vapor or air flowing through the mouthpiece as a flow rate of the air flowing through the airflow passage increases over a range of airflow rates. Gill teaches a vapor inhaler wherein an induction coil is energized as necessary to maintain the temperature of the vapor inhaled by the user [0051]. It would have been obvious to one of ordinary skill in the art to apply this configuration to the device of Raichman such that the controller controls operation of the heating element based on the airflow rate, at least maintaining a temperature of the vapor (and air) flowing through the mouthpiece, including as a flow rate of the air increases over a range of airflow rates, so that the user is provided with a constant temperature.
