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 1-2, 4-6, 12-13, 23, 31, 36, 47-48 and 64 are rejected under 35 U.S.C. 103 as being unpatentable over Biondi.

Biondi does not expressively disclose a ventilator housing that the ventilator and controller are disposed within. However, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to incorporate a housing onto the apparatus of Biondi in order to protect the components of the ventilator and embedded controller.
Regarding claim 2, modified Biondi discloses the apparatus of claim 1. Biondi further discloses if the fault mode condition is determined to exist at the particular time, the ventilator controller controls the mechanical ventilation apparatus of the ventilator in delivering the mechanical ventilation to the patient according to at least one of: previously stored ventilation control parameter values and previously stored last received valid ventilation control parameter values (par 0083 discloses last known valid and predefined/previously stored valid).
Regarding claim 4, modified Biondi discloses the apparatus of claim 1. Biondi further discloses the ventilator controller is configured to: determine whether the fault mode condition exists, wherein the fault mode condition is associated with the ventilator (the fault mode condition is considered to be associated with the respiratory distress management device as it is associated with the breath control structure to be implemented), and wherein the at least one source is separate from the ventilator (see fig 1 showing the display controller/at least one source #12 being separate from the embedded controller #14, further par 0031 disclosing 14 as an embedded controller interfacing the ventilator and 12 as a display controller for interfacing the clinician).
Regarding claim 5, modified Biondi discloses the apparatus of claim 1. Biondi further discloses the ventilator controller is configured to: determine whether a fault mode condition exists at a particular time (par 0043 the particular time being upon receiving the breath control structure from the at least one source), wherein the particular time is a first predetermined time (the predetermined time being upon receiving the breath control structure); if the fault mode condition is determined not to exist at the first predetermined time, enable control of the mechanical ventilation apparatus of the ventilator by at least one source in delivering mechanical ventilation to the patient, via signals received by the ventilator controller from the at least one source (par 0043 discloses the controller 14 determining the structure received from at least one source, #12 fig 1, is valid and thus controlling the ventilator according to the received structure); and if the fault mode condition is determined to exist at the first predetermined time, control the mechanical ventilation apparatus of the ventilator in delivering the mechanical ventilation to the patient (par 0083 discloses the controller determining the structure received from at least one source to be invalid and instead controlling the ventilator based on previous valid structures or a predefined structure).

Claim 50 is rejected under 35 U.S.C. 103 as being unpatentable over modified as applied to claim 1 above and further in view of Poltorak (US 9,942,051 B1).
Regarding claim 50, modified Biondi discloses the apparatus of claim 1. Biondi is silent to the ventilator controller is configured to perform processing utilizing at least one of: task prioritization, data sampling protection, one or more histograms in data handling in order to minimize data noise, a single thread configuration, thread-safe operating system objects, a round robin software processing design in order to minimize processing delay, performance of token count checks on ventilation control data received from the at least one source, disabling of software processing interrupts under one or more conditions, prioritization with respect to one or more aspects of communication with the at least one source, one or more checks relating to a ventilation control data receipt rate from the at least one source, maintenance of a minimum portion of unused memory in order to protect against potential data storage overload, an acknowledgement (ACK) and non-acknowledgement (NACK) scheme in ensuring receipt of ventilation control data from the at least one source, an automatic reset in the event of a software processing freeze or deadlock condition, continuous communication between the ventilator and the at least one source in correcting any data receipt errors continuously, and one or more checks to ensure that the at least one source is properly configured for communication with the respiratory distress management device.
Poltorak teaches the use of round robin software processing (col 23 ln 13-15).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to perform the processing of modified Biondi utilizing round robin processing as taught by Poltorak as round robin is a known software processing method.
Response to Arguments
Applicant's arguments filed 10/06/2025 have been fully considered but they are not persuasive.
Applicant has amended the claims to specify the controller as the “ventilator controller” and the “at least one source” as being separate from the ventilator. Applicant asserts par 0031 of Biondi discloses all of fig 1 as the ventilator and that both controllers 12 and 14 are thus the ventilator controller (see pg 15 of response filed 10/06/2025), therefore the source is not sperate from the ventilator. Further it is clear from figure 1 that figure 1 does not show only components of the ventilator as the figure additionally shows the clinician and the patient, which are plainly considered as human beings and not part of the ventilator. Fig 1 and par 0031 further explicitly state #17 as the ventilator. Therefore, presence in figure 1 does not automatically constitute an element as part of the ventilator. Further par 0031 in full discloses controller 14 specifically as an “embedded controller” for interfacing the ventilator and it is therefore seen that controller 14 is the “ventilator controller”. Par 0031 further discloses controller 12 as a controller associated with a display for interfacing with a clinician. Therefore controller 12 is seen as a display controller separate from the ventilator 17 itself. Applicants arguments are therefor not persuasive. Applicant additionally makes assertions that Biondi fails to disclose certain aspects of the claim involving the fault mode conditions (see pg 15-16 of response filed 10/06/2025). However, applicant only asserts this without providing explanation of how what Biondi discloses and was noted in the rejections fails to meet the limitations. Applicant reasserts these points regarding all the independent claims and dependent claims. Applicants arguments are not persuasive and the examiner upholds the rejections.
