Claim Rejections – 35 U.S.C. § 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 1-10, 15 and 16 are rejected under 35 U.S.C. 103 as obvious over Steven (WO 2021231585 A1) in view of Cull (WO 0192793 A1), further in view of heavydutykits.com (https://www.heavydutykits.com/product/oil-cooler-donut-1004-42-perkins-p2486a218/?srsltid=AfmBOooibyLSLZom7ip-hTAH_xwQLSOMCpdBH_WYHqNaWFyCa-ln1i0C), hereinafter HDK.
Regarding claim 1, Steven discloses an air-purifying respirator (Steven pg.1 Summary line 1: air processing system; used as a respirator and has means to purify air) comprising:
a coolant container comprising coolant material (Steven pg. 19 [02] lines 1-4; the insulated cooling reservoir is a coolant container (Figures 29A-C: ‘300’) with means to comprise a housing to be mounted on it for air cooling, pg. 18 [07]; the cooling system with the coolant container (insulated volume of space) can comprise a material with thermal inertia (ice, ice water, at least one of either ice or water));
and a breathing tube entering the coolant container through a coolant container entrance opening of the coolant container (Steven pg. 18 [07]; a tube for breathing (Figures 29A/D/E: ‘334’) can enter the insulated volume and come into contact with the coolant material within the coolant container – thereby having a coolant container entrance opening at the centrifugal blower area of the container);
and exiting the coolant container through a coolant container exit opening of the coolant container (Steven Figure 29A; the tube goes in from the centrifugal blower as ‘334’ then goes through the system and exits through ‘315’ to then provide air towards the user- thereby having an exit to the container).
Steven is silent to a refrigerant evaporator, a central hole and wherein the refrigerant evaporator is positioned within a least a portion of the central hole of the coolant container.
Cull discloses a cooling system comprising:
a refrigerant evaporator (Figure 2 below; refrigerant evaporator);
It would have been obvious to a person of ordinary skill in the art, before the effective filing date of the claimed invention, to modify the air purifying respirator with a coolant container and a breathing tube of Steven to include a refrigerant evaporator as taught by Cull, since, refrigerant evaporators provide additional cooling and because a refrigerant evaporator can be a part of a heat exchange unit that has self-chilling properties with a coolant container, leading to even more additional cooling on top of having just a coolant container with the breathing tube (Cull pg.7 [02]).
Steven in view of Cull is silent to a coolant container with a central hole and wherein the refrigerant evaporator is positioned within the central hole of the container.
HDK discloses a coolant container wherein,
the coolant container defines a central hole (Figure 1 below; central hole)
and wherein at least a portion of the refrigerant evaporator is positioned within the central hole of the container (Figure 1 below; the central hole has threading for an attachment that could go into the central hole).
and an entrance and an exit opening of the coolant container (Figure 1 below; entrance and exit of the coolant container, wherein a breathing tube if container is sized up could go into the entrance and exit of the container).
Furthermore, it would have been obvious to a person of ordinary skill in the art, to modify the air purifying respirator of Steven in view of the cooling system of Cull with the coolant container having a central hole of HDK, since providing the central hole allows for maximum heat transfer between the refrigerant evaporator and the coolant container (hvacrschool.com [2]; evaporators with an increased surface area being covered gives more contact time and enables a greater heat transfer) and because mere scaling up of a prior art process capable of being scaled up, if such were the case, would not establish patentability in a claim to an old process so scaled, such that scaling up the size of the coolant container of HDK, would not establish patentability, MPEP 2144.03 IV(A).

Regarding claim 2, modified Steven in view of HDK further discloses the air-purifying respirator of claim 1.
Steven discloses the air processing system,
wherein the breathing tube comprises a cooling portion in contact with the coolant material (Steven pg. 18 [07]; a tube for breathing (Figures 29A/D/E: ‘334’) can enter the insulated volume and come into contact with the coolant material within the coolant container).
Steven is silent to a breathing tube at least partially surrounding the central hole.
HDK discloses the coolant container,
wherein an air tube can go inside the entrance and exit openings to at least partially surround the central hole (Figure 1 above; entrance and exit of the coolant container, wherein a breathing tube if container is sized up could go into the entrance and exit of the container).
It would have been obvious to a person of ordinary skill in the art, before the effective filing date of the claimed invention, to include the breathing tube surrounding a central hole, since the refrigerant evaporator can be placed in the central hole and this allows for additional cooling to the breathing tube itself and the air within the breathing tube (hvacrschool.com [2]; evaporators with an increased surface area being covered gives more contact time and enables a greater heat transfer), thus having the breathing tube arranged around the central hole within the coolant container provides additional cooling to the air flowing within the tube.
Regarding claim 3, modified Steven in view of HDK further discloses the air-purifying respirator of claim 1,
wherein the refrigerant evaporator defining a refrigerant flow channel and a refrigerant circulation opening (Figure 2 above; refrigerant flow channel and refrigerant circulation opening);
wherein the refrigerant circulation opening is connected to the refrigerant flow channel (Figure 2 above; the refrigerant circulation opening is connected to the refrigerant flow channel via the inlet tube ‘76’).
Regarding claim 4, modified Steven in view of HDK further discloses the air-purifying respirator of claim 3,
wherein the refrigerant evaporator comprises refrigerant material (Cull pg.4 [05]; refrigerant is supplied to the adapter unit as depicted in (Figure 2 above)).
Regarding claim 5, modified Steven in view of HDK further discloses the air-purifying respirator of claim 4,
wherein the refrigerant material enters the refrigerant flow channel through the refrigerant circulation opening (Cull pg.4 [05]; refrigerant is supplied to the adapter and connected to a refrigerant material that comes from the inlet ‘76’ of Figure 2 above).
Regarding claim 6, modified Steven in view of HDK further discloses the air-purifying respirator of claim 1, wherein the breathing tube enters the coolant container through a front coolant container entrance opening of the coolant container and exits the coolant container through a front coolant container exit opening of the coolant container (Steven pg. 18 [07]; a tube for breathing (Figures 29A/D/E: ‘334’) can enter the insulated volume and come into contact with the coolant material within the coolant container – thereby having a coolant container entrance opening at the centrifugal blower area of the container and Figure 29A; the tube goes in from the centrifugal blower as ‘334’ then goes through the system and exits through ‘315’ to then provide air towards the user- thereby having an exit to the container).
There is no evidence of record that establishes that changing the orientation of the coolant container, (with the entrance and exit openings having a front/top/bottom/left/right opening), and the refrigerant evaporator with respect to the breathing tube and the air-purifying respirator, would result in a functional difference of the Steven device. Further, a person having ordinary skill in the art, being faced with modifying the portable air processing system of Steven, would have a reasonable expectation of success in making such a modification and it appears the system would function as intended being given the claimed orientations of the coolant container, refrigerant evaporator and the breathing tube. Lastly, Applicant has not disclosed that the claimed orientation of the coolant container, refrigerant evaporator and breathing tube solves any stated problem, that such an orientation produces an unexpected result.
Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the portable air processing system of Steven to have the exact orientations of the claimed refrigerant evaporator and coolant container, (with the entrance and exit openings having a front/top/bottom/left/right opening), as an obvious matter of design choice within the skill of the art.
Regarding claim 7, modified Steven in view of HDK further discloses the air-purifying respirator of claim 1, wherein the breathing tube enters the coolant container through a bottom coolant container entrance opening of the coolant container and exits the coolant container through a top coolant container exit opening of the coolant container (Steven pg. 18 [07]; a tube for breathing (Figures 29A/D/E: ‘334’) can enter the insulated volume and come into contact with the coolant material within the coolant container – thereby having a coolant container entrance opening at the centrifugal blower area of the container and Figure 29A; the tube goes in from the centrifugal blower as ‘334’ then goes through the system and exits through ‘315’ to then provide air towards the user- thereby having an exit to the container).
Regarding claim 8, modified Steven in view of HDK further discloses the air-purifying respirator of claim 1, wherein the breathing tube enters the coolant container through a left coolant container entrance opening of the coolant container and exits the coolant container through a top coolant container exit opening of the coolant container (Steven pg. 18 [07]; a tube for breathing (Figures 29A/D/E: ‘334’) can enter the insulated volume and come into contact with the coolant material within the coolant container – thereby having a coolant container entrance opening at the centrifugal blower area of the container and Figure 29A; the tube goes in from the centrifugal blower as ‘334’ then goes through the system and exits through ‘315’ to then provide air towards the user- thereby having an exit to the container).
Regarding claim 9, modified Steven in view of HDK further discloses the air-purifying respirator of claim 1, wherein the breathing tube enters the coolant container through a top coolant container entrance opening of the coolant container and exits the coolant container through a top coolant container exit opening of the coolant container (Steven pg. 18 [07]; a tube for breathing (Figures 29A/D/E: ‘334’) can enter the insulated volume and come into contact with the coolant material within the coolant container – thereby having a coolant container entrance opening at the centrifugal blower area of the container and Figure 29A; the tube goes in from the centrifugal blower as ‘334’ then goes through the system and exits through ‘315’ to then provide air towards the user- thereby having an exit to the container).
Regarding claim 10, modified Steven in view of HDK further discloses the air-purifying respirator of claim 1, wherein the breathing tube enters the coolant container through a right coolant container entrance opening of the coolant container and exits the coolant container through a left coolant container exit opening of the coolant container (Steven pg. 18 [07]; a tube for breathing (Figures 29A/D/E: ‘334’) can enter the insulated volume and come into contact with the coolant material within the coolant container – thereby having a coolant container entrance opening at the centrifugal blower area of the container and Figure 29A; the tube goes in from the centrifugal blower as ‘334’ then goes through the system and exits through ‘315’ to then provide air towards the user- thereby having an exit to the container).
Claims 11, 12, and 14 are rejected under 35 U.S.C. 103 as obvious over Steven (WO 2021231585 A1) in view of Cull (WO 0192793 A1), further in view of HDK (https://www.heavydutykits.com/product/oil-cooler-donut-1004-42-perkins-p2486a218/?srsltid=AfmBOooibyLSLZom7ip-hTAH_xwQLSOMCpdBH_WYHqNaWFyCa-ln1i0C), and even further in view of Schmidt (WO 2021219151 A1).
Regarding claim 11, modified Steven in view of HDK discloses the air-purifying respirator of claim 1.
Steven discloses the air processing system further comprising:
a centrifugal blower (Steven Summary pg. 4 [01] line 8; centrifugal blower).
and a filter cartridge (Steven pg. 5 [04]; there can be a mechanical filter (filter cartridge is type of mechanical filter) that can have a replaceable component such as the filter itself and Figure 15; general embodiment of the heat exchanger system, ‘59’ is a filter that takes in ambient air from the one side through the pipeline system);
Steven fails to disclose a blower assembly housing with a sunken surface, where the blower is disposed inside, a filter cartridge on the sunken surface of a blower assembly housing and a filter cartridge comprising coolant material.
Schmidt discloses a respirator mask containing:
a blower assembly housing defining a sunken surface, wherein a blower is disposed in the blower assembly housing (Figure 3 below; where the blower assembly housing is the whole piece ‘53’ because the blower is inside of it, the sunken surface is defined by an arrow);
and a filter positioned on the sunken surface of the blower assembly housing, wherein the filter comprises the coolant material (Figure 3 below; the filter is also behind the vents within the sunken portion of the housing because it is inside the vent portion – thereby being the sunken surface, Schmidt General Description [049]; coolant can be injected into the filter (filter comprising the coolant material- housing is seen in Figure 4 below)).
It would have been obvious to a person of ordinary skill in the art, before the effective filing date of the claimed invention, to modify the air processing device of Steven to include a blower assembly with a sunken surface, wherein the blower is disposed in the blower assembly housing and to have a filter cartridge within the sunken surface with a coolant material as taught by Schmidt, since, having a filter with coolants helps to keep the area moist and/or to regenerate or bind pollutants better, and because including the blower and filter cartridge on the sunken surface allows for the blower and filter to work directly with the air duct output to form an air curtain throughout the system back to the user (Schmidt General Description [049], Brief Description of the Invention [016]).

wherein a blower inlet opening of the blower is on the sunken surface (Schmidt Figure 18; where the blower ‘102’ is on the sunken surface (Figure 3 above), and the opening of the blower is on the sunken surface because it disposed inside).
It would have been obvious to a person of ordinary skill in the art, before the effective filing date of the claimed invention, to modify the air processing device of Steven to include the blower inlet opening on the sunken surface as taught by Schmidt, since, including the blower on the sunken surface allows for the blower to work directly with the air duct output to form an air curtain throughout the system back to the user, therefore, if the blower inlet opening of the blower is on the sunken surface, it would also be working directly to form an air curtain for the user (Schmidt General Description [049], Brief Description of the Invention [016]).
Regarding claim 14, modified Steven in view of HDK, further in view of Schmidt discloses the air-purifying respirator of claim 11.
Steven discloses the portable air processing system,
wherein the coolant material comprises water (Steven pg. 18 [07]; the cooling system with the coolant container (insulated volume of space) can comprise a material with thermal inertia (ice, ice water, at least one of either ice or water)).

Deakin discloses the cooling garment,
wherein the coolant material comprises ammonium nitrate (Deakin [0034]; preferably the coolant is a first and a second reactant: can be ammonium nitrate and/or water).
It would have been obvious to a person of ordinary skill in the art, before the effective filing date of the claimed invention, to modify the modified respirator of Steven in view of HDK, further in view of Schmidt to include ammonium nitrate as a coolant material as taught by Deakin, since, ammonium nitrate has a high solubility allowing it to have an advantageous cooling power than other salts (eurekaalert.org[1] [03]).
Claims 15, 16, and 18 are rejected under 35 U.S.C. 103 as obvious over Steven (WO 2021231585 A1) in view of Cull (WO 0192793 A1), further in view of HDK (https://www.heavydutykits.com/product/oil-cooler-donut-1004-42-perkins-p2486a218/?srsltid=AfmBOooibyLSLZom7ip-hTAH_xwQLSOMCpdBH_WYHqNaWFyCa-ln1i0C), and even further in view of Davis (US 20100242865 A1).
Regarding claim 15, modified Steven in view of HDK, further discloses the air-purifying respirator of claim 1, further comprising:
