However, Errico does not specifically discloses wherein the software application controls the user interface to prompt a user to enter user status information and to compare the user status information with the parameters of the stimulator. Simon discloses wherein the software application controls the user interface to prompt a user to enter user status information and to compare the user status information with the parameters of the stimulator (abstract, page 37, claim 10). This allows to monitor compliance and the effectiveness of the therapy being delivered. Therefore, it would have been obvious to one of ordinary skill in the art, at the time of the invention, to modify the device of Errico by adding software application controls the user interface to prompt a user to enter user status information and to compare the user status information with the physiological parameter as taught by Simon in order to facilitate monitor compliance and the effectiveness of the therapy being delivered. Regarding claim 22, Errico in view of Simon, specifically Errico discloses the user status information comprises one or more of: level of pain, satisfaction level, mood, medication use (Section 0079, Also included in the system is a measuring stage which measures and displays the electrical stimulation signal operating on the substance being treated, as well as the outputs of various sensors which sense prevailing conditions prevailing in this substance), activity level, and amount of sleep.

Regarding claim 24, Errico in view of Simon, specifically Errico discloses the stimulator is configured to apply a plurality of single doses (section 0036, There may be from about 1 to about 20 pulses per burst, preferably about five pulses. Each pulse within a burst has a duration from about 20 to about 1000 microseconds, preferably about 200 microseconds), wherein each single dose comprises applying the electrical impulse for a duration of between about 30 seconds and 5 minutes (section 0181, 0182, a trigeminal nerve stimulation treatment according to the present invention is conducted for continuous period of thirty seconds to thirty minutes, preferably about 90 seconds to about 5 minutes and more preferably about two minutes (each defined as a single dose). each treatment session comprises 1-3 doses administered by the patient either consecutively or separated by 5 minutes). Regarding claim 25, Errico in view of Simon, specifically Errico discloses the parameters include a number of single doses applied by the stimulator (Section 0082, each treatment session comprises 1-3 doses administered by the patient either consecutively or separated by 5 minutes). Regarding claim 26, Errico in view of Simon, specifically Simon discloses the software application is configured to adjust the parameters of the stimulator based on the user status information (abstract, 0127). Regarding claim 27, Errico in view of Simon, specifically Errico discloses the software application is configured to provide an alert based on the user status information, the alert prompting the user to adjust the parameters of the stimulator (section 0175, 0193, Having received such preliminary information from the patient, the computer programs will perform instrument diagnostic tests and make the stimulator ready for the stimulation session. The system also receives input from the "Controller", which in this case may comprise the nerve stimulation device, as well as electronic components that may be used to select or set parameters for the stimulation protocol (amplitude, frequency, pulse width, burst number, etc.) or alert the patient as to the need to use or adjust the stimulator). Claim(s) 4, 9-12, 17, and 22 is/are rejected under 35 U.S.C. 103 as being unpatentable over Errico et al (US 20140330336) in view of Simon (US 20220079502) and in view of Romaniw et al. (US 20230364413), all cited previously. Regarding claim 4, Errico in view of Simon in view of Romaniw, specfically Romaniw discloses the user status information comprises one or more of: level of pain, satisfaction level, mood, medication use, activity level, and amount of sleep (section 0071, the devices may be used as a bridge-therapy for alcohol dependence or opioid-use disorders to reduce opioid or alcohol cravings sufficiently to remain drug-free prior to receiving further treatment, such as prescription injection medications or other alcohol and drug recovery programs). This allows for proper treatment to addiction or opioid use disorders. Therefore, it would have been obvious to one of ordinary skill in the art, at the time of the invention, to modify the device of Errico by adding the user status information comprises one or more of: level of pain, satisfaction level, mood, medication use, activity level, and amount of sleep as taught by Romaniw in order to facilitate proper treatment to addiction or opioid use disorders.

This indicates an optimal position for placement of the electrodes to transmit the electrical impulses through the skin surface to the underlying vagus nerve. Therefore it would have been obvious to one of ordinary skill in the art, at the time of the invention, to modify the device of Errico by adding the sensor comprises a heart pulse sensor as taught by Romaniw in order to facilitate an finding an optimal position for placement of the electrodes to transmit the electrical impulses through the skin surface to the underlying vagus nerve by using a heart pulse sensor that is configured to detect a heart pulse emanating from the carotid artery in the patient’s neck. Regarding claim 10, Errico in view of Simon discloses in view of Romaniw, specfically Romaniw discloses an indicator coupled to the sensor for providing an alert when the heart pulse is detected (Section 0017, the indicator is configured to transmit an alert that is associated with the magnitude of the heart pulse. For example, the alert may comprise an audible sound that increases in decibel level as the magnitude increase). This indicates an optimal position for placement of the electrodes to transmit the electrical impulses through the skin surface to the underlying vagus nerve. Regarding claim 11, Errico in view of Simon discloses in view of Romaniw, specfically Romaniw discloses the target location is a location on the outer skin surface adjacent to, near, or overlying the carotid artery (Section 0015, the sensor comprises a heart pulse sensor that is configured to detect a heart pulse emanating from the carotid artery in the patient’s neck). This indicates an optimal position for placement of the electrodes to transmit the electrical impulses through the skin surface to the underlying vagus nerve. Regarding claim 12, Errico in view of Simon discloses in view of Romaniw, specfically Romaniw discloses the selected nerve is the vagus nerve (Section 0015, The vagus nerve is situated within the carotid sheath, near the carotid artery and the interior jugular vein. This indicates an optimal position for placement of the electrodes to transmit the electrical impulses through the skin surface to the underlying vagus nerve). This indicates an optimal position for placement of the electrodes to transmit the electrical impulses through the skin surface to the underlying vagus nerve. Regarding claim 17, Errico in view of Simon discloses in view of Romaniw, specfically Romaniw discloses a patch having an adhesive surface for attached to the outer skin surface of the neck of the patient, wherein the electrode is housed within the patch (Fig. 12, section 0026, the device comprises a patch having at least one adhesive surface for attachment to the outer skin surface of the neck of the patient). This allows for proper secure placement of the electrode on the target area. Regarding claim 22, Errico in view of Simon discloses in view of Romaniw, specfically Romaniw discloses the user status information comprises one or more of: level of pain, satisfaction level, mood, medication use, activity level, and amount of sleep (section 0071, the devices may be used as a bridge-therapy for alcohol dependence or opioid-use disorders to reduce opioid or alcohol cravings sufficiently to remain drug-free prior to receiving further treatment, such as prescription injection medications or other alcohol and drug recovery programs). This allows for proper treatment to addiction or opioid use disorders.
