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.
Claim(s) 1-2, 5, 13-14, and 16 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ein (US 2002/0026226 A1), hereinafter Ein in view of Chen et al. (US 2022/0013704 A1), hereinafter Chen.
Regarding claim 1, Ein discloses a device (therapeutic apparatus 10) comprising:
a Peltier ([0076] “The apparatus generally includes…at least one TE device (here, shown as a thermal area or thermal plate 30)”, [0079] “The TE devices of the present invention are based on the Peltier Effect…hence, are called Peltier devices”, Claim 23, TE devices 52) ;
a power supply ([0094] “The power unit 70 provides the necessary power to the therapeutic apparatus. The power unit 70 includes a power supply 74, such as several batteries or fuel cells”) in electrical communication with the Peltier (view Figures 5 and 6);
a control switch (second switch, polarity switch 84) electrically coupled to the power supply and the Peltier ([0018] “The control unit of the therapeutic apparatus generally includes a controller, a first switch, and a second switch. The controller controls a desired temperature to be delivered to the body surface. The first switch, responsive to the actual temperature detected by the temperature sensor, disconnects the power unit when the actual temperature is above a maximum temperature or below a minimum temperature. The second switch communicates with the TE device to control the direction of current through the TE device and, hence, its operation as a heater or a cooler.”, view Figures 5 and 6), wherein the control switch is configured to control direction of current supplied from the power supply to the Peltier ([0018] “The second switch communicates with the TE device to control the direction of current through the TE device and, hence, its operation as a heater or a cooler.”); and
at least one flexible layer (wrap 16) coupled to the Peltier, wherein the at least one flexible layer is configured to retain the Peltier about a portion of a subject ([0076] “at least one TE device (here, shown as a thermal area or thermal plate 30 mounted to the wrap 16 to deliver a desired temperature to the body surface”, [0086] “The wrap 40 also includes a first insulate layer 50 and contact the outer wiring/tubing layer 53 and has embedded within the wiring/tubing layer the TE device 52 and a second insulate layer 51 which is in contact with the inner wiring/tubing layer 53. A first elastic layer 58 is disposed between the outer layer 42 and the first conductive layer 54, and a second elastic layer 60 is disposed between the inner layer 44 and the second conductive layer 56. These layers 58, 60 preferably are composed of a ventilated cushion material designed to enable the wrap to conform to the contours of the body surface to which the wrap 40 is attached.”) .
Ein fails to disclose wherein the Peltier is a flexible Peltier.
However, Chen teaches a wearable thermoelectric device for personalized thermos-regulation comprising a flexible Peltier (view Figure 12A-12B, Figure 19A-B, Figure 25-27, [0003] “The present document discloses design and fabrication methods for mechanically flexible and/or stretchable thermoelectric devices for wearable personalized thermo-regulation”).
It would have been prima facie obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to have substituted the Peltier of Ein with the flexible Peltier of Chen as these prior art references are directed to wearable thermoregulator devices providing cooling and heating to a user. One would be motivated to do this as this would allow the device to have a conformal coverage of the skin ([0189]) and for easy attachment to complex surfaces of the skin with long-term use .
Regarding claim 2, Ein in view of Chen teaches the device of claim 1 (as shown above). Ein further discloses the device further comprising a temperature sensor (temperature sensor 28), wherein the temperature sensor is configured to control application of current from the power supply to the flexible Peltier ([0076] “Heating or cooling depends in part on inputs to the control unit of the electronics package from the temperature sensors 28. The temperature sensors 28 provide feedback to the control unit; the control unit then adjusts the current applied to the TE device to deliver a current corresponding to the desired temperature required from the TE device.”).
Regarding claim 13, Ein discloses a method of treating a patient ([0002] “this invention relates to a portable therapeutic apparatus for heating and cooling a body surface of a user”, [0069] “the therapeutic apparatus can be used as a therapeutic device to supply heat or coolness to a targeted body surface of the user and, in some embodiments, electrical stimulation and iontophoresis medication to the body surface to treat various medical ailments and conditions”, [0072]) the method comprising:
coupling a thermal treatment device to a subject ([0071]-[0072] “Each therapeutic apparatus generally includes a wrap 16 adapted to be secured to the target body surface…The glove wrap can also provide heat to the user's hand to treat arthritis. The shoulder wrap 10 provides therapeutic cooling for shoulder injuries incurred in accidents (e.g., sports, vehicular, etc.) and therapeutic heating for medical conditions such as bursitis or arthritis”), wherein the thermal treatment device (therapeutic apparatus 10) comprises:
a Peltier ([0076] “The apparatus generally includes…at least one TE device (here, shown as a thermal area or thermal plate 30)”, [0079] “The TE devices of the present invention are based on the Peltier Effect…hence, are called Peltier devices”, Claim 23, TE devices 52);

a control switch (second switch, polarity switch 84) electrically coupled to the power supply and the Peltier ([0018] “The control unit of the therapeutic apparatus generally includes a controller, a first switch, and a second switch. The controller controls a desired temperature to be delivered to the body surface. The first switch, responsive to the actual temperature detected by the temperature sensor, disconnects the power unit when the actual temperature is above a maximum temperature or below a minimum temperature. The second switch communicates with the TE device to control the direction of current through the TE device and, hence, its operation as a heater or a cooler.”, view Figures 5 and 6),
at least one flexible layer (wrap 16) coupled to the Peltier,
retaining the thermal treatment device about a portion of a subject using the at least one flexible layer ([0076] “at least one TE device (here, shown as a thermal area or thermal plate 30 mounted to the wrap 16 to deliver a desired temperature to the body surface”, [0086], Abstract: “A thermal apparatus includes a wrap adapted to be secured to the body surface of a user. At least one temperature sensor is mounted to the wrap to measure an actual temperature of the body surface, and at least one thermoelectric device is mounted to the wrap to selectively deliver heat to and remove heat from the body surface.”);
controlling direction of current supplied from the power supply to the Peltier using the control switch ([0018] “The second switch communicates with the TE device to control the direction of current through the TE device and, hence, its operation as a heater or a cooler.”, [0096]) ; and
applying heat or cooling to the subject based on the controlling ([0076] “Heating or cooling depends in part on inputs to the control unit of the electronics package from the temperature sensors 28. The temperature sensors 28 provide feedback to the control unit; the control unit then adjusts the current applied to the TE device to deliver a current corresponding to the desired temperature required from the TE device.”).
Ein fails to disclose wherein the Peltier is a flexible Peltier.
However, Chen teaches a wearable thermoelectric device for personalized thermos-regulation comprising a flexible Peltier (view Figure 12A-12B, Figure 19A-B, Figure 25-27, [0003] “The present document discloses design and fabrication methods for mechanically flexible and/or stretchable thermoelectric devices for wearable personalized thermo-regulation”).
It would have been prima facie obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to have substituted the Peltier of Ein with the flexible Peltier of Chen as these prior art references are directed to wearable thermoregulator devices providing cooling and heating to a user. One would be motivated to do this as this would allow the device to have a conformal coverage of the skin ([0189]) and for easy attachment to complex surfaces of the skin with long-term use .
Regarding claim 13, Ein in view of Chen teaches the method of claim 13 (as shown above). Ein further discloses the method further comprising: controlling application of current from the power supply to the flexible to control a temperature of the thermal treatment device ([0076] “Heating or cooling depends in part on inputs to the control unit of the electronics package from the temperature sensors 28. The temperature sensors 28 provide feedback to the control unit; the control unit then adjusts the current applied to the TE device to deliver a current corresponding to the desired temperature required from the TE device.”).
Regarding claims 5 and 16, Ein in view of Chen teaches the device of claim 1 and the method of claim 13 (as shown above). Ein further discloses wherein the thermal treatment device (therapeutic apparatus 10) further comprises: a thermal pad (first, or outer conductive layer 54) coupled to the at least one flexible layer (Figure 4A, [0086] “A first elastic layer 58 is disposed between the outer layer 42 and the first conductive layer 54, and a second elastic layer 60 is disposed between the inner layer 44 and the second conductive layer 56. These layers 58, 60 preferably are composed of a ventilated cushion material designed to enable the wrap to conform to the contours of the body surface to which the wrap 40 is attached.”), wherein the thermal pad is configured to conduct heat to and from the flexible Peltier ([0088] “The outer conductive layer 54 has a larger surface area than the inner conductive layer 56 so that, when the TE devices 52 are functioning in a cooling mode, heat generated at the outer conductive layer 54 is dissipated across a relatively large surface area.”). (also view pertinent prior art made of record Choi)
Claim(s) 3-4 and 15 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ein in view of Chen as applied to claims 1 and 13 above, and further in view of Choi, Jaeyoo, et al. "Lightweight wearable thermoelectric cooler with rationally designed flexible heatsink consisting of phase-change material/graphite/silicone elastomer." Journal of Materials Chemistry A 9.28 (2021): 15696-15703., hereinafter Choi.
Regarding claim 3, Ein in view of Chen teaches the device of claim 1 (as shown above). Ein further discloses the device further comprising: at least one heat sink layer ([0091] “The strip line enables the outer conductive layer 54 to create a heat sink effect by which excessive heat/cold is vented to the outside of the cast.”).
Ein and Chen, alone or in combination, fail to teach wherein the at least one heat sink layer comprises graphite.
However, Choi teaches a lighweight wearable thermoelectric (TE) cooler device with a flexible heatsink wherein the at least one heat sink layer comprises graphite (pg. 15697, Results and Discussion, Design of the wearable TE cooler: “a lightweight and flexible heatsink which was prepared with a ternary hybrid of silicone elastomer, PCM, and graphite powder.”).
It would have been prima facie obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Ein and Chen to incorporate the teachings of Choi to have the at least one heat sink later comprise of graphite, as these prior art references are directed to wearable thermoelectric devices. One would be motivated to do this as graphite improves the thermal conductivity of the flexible heatsink, as recognized by Choi (pg. 15697, Results and Discussion, Design of the wearable TE cooler).
Regarding claim 4, Ein in view of Chen in view of Choi teaches the device of claim 3 (as shown above). Ein and Chen, alone or in combination, fail to teach wherein the at least one heat sink layer is configured to absorb or provide heat to the flexible Peltier.
However, Choi discloses wherein the at least one heat sink layer is configured to absorb heat to the flexible Peltier (pg. 15697, Results and Discussion, Design of the wearable TE cooler: “This layer was combined with a lightweight and flexible heatsink which was prepared with a ternary hybrid of silicone elastomer, PCM, and graphite powder. Here, the PCM is able to absorb and store the thermal energy at a specific temperature range, originated from its phase changing from solid to liquid.”).
It would have been prima facie obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Ein and Chen to incorporate the teachings of Choi to have the at least one heat sink layer be configured to absorb heat or provide heat to the flexible Peltier, as these prior art references are directed to wearable thermoelectric devices. One would be motivated to do this maintain and maximize cooling, as recognized by Choi (pg. 15697, Introduction, Figure 3).
Regarding claim 15, Ein in view of Chen teaches the method of claim 13 (as shown above). Ein and Chen, alone or in combination, fail to teach wherein the thermal treatment device further comprises: at least one heat sink layer comprises graphite, wherein the at least one heat sink layer is configured to absorb or provide heat to the flexible Peltier.
However, Choi discloses wherein the thermal treatment device (Figure 1(c) and (d): proposed wearable TE cooler) further comprises: at least one heat sink layer comprises graphite (pg. 15697, Results and Discussion, Design of the wearable TE cooler: “a lightweight and flexible heatsink which was prepared with a ternary hybrid of silicone elastomer, PCM, and graphite powder.”), wherein the at least one heat sink layer is configured to absorb or provide heat to the flexible Peltier (pg. 15697, Results and Discussion, Design of the wearable TE cooler: “This layer was combined with a lightweight and flexible heatsink which was prepared with a ternary hybrid of silicone elastomer, PCM, and graphite powder. Here, the PCM is able to absorb and store the thermal energy at a specific temperature range, originated from its phase changing from solid to liquid.”).
It would have been prima facie obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Ein and Chen to incorporate the teachings of Choi to have the at least one heat sink later comprise of graphite, as these prior art references are directed to wearable thermoelectric devices. One would be motivated to do this maintain and maximize cooling, as recognized by Choi (pg. 15697, Introduction, Figure 3).
Claim(s) 6 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ein in view of Chen as applied to claim 1 above, and further in view of Ang, Elisa YM, et al. "Multi-stage thermoelectric coolers for cooling wearables." Thermal science and engineering progress 36 (2022): 101511., hereinafter Ang.
Regarding claim 6, Ein in view of Chen discloses the device of claim 1 (as shown above). Ein and Chen, alone or in combination, fail to teach the device further comprising a second flexible Peltier, wherein the flexible Peltier and the second flexible Peltier are stacked within the device.
However, Ang teaches a multi-stage TECs design that is suitable for use in cooling wearables such as thermal-regulating wearables used against human skin (pg. 1, Introduction), the design further comprising a second flexible Peltier, wherein the flexible Peltier and the second flexible Peltier are stacked within the device (Figure 4: 2 Stage TEC1-12703, pg. 2, 2.Methods: “The TEC1-12703 is then layered up to validate results for the 2 stage TEC”, pg. 5, 3.1 Current ratio of Multi-Stage TEC: “2 stages (two layers of TEC1-12703 with one stacked on top of the other)” )
It would have been prima facie obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Ein and Chen to incorporate the teachings of Ang to have the device further comprise a second flexible Peltier, wherein the flexible Peltier and the second flexible Peltier are stacked within the device, as these prior art references are directed to wearable Peltier devices for thermoregulation. One would be motivated do this as a multi-stage Peltier can significantly lower a temperature of the cooling side, providing significant cooling against human skin, as recognized by Ang (pg. 11, 4.Conclusion).
Claim(s) 7-12 and 17-20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ein in view of Chen as applied to claims 1 and 13 above, and further in view of Lee et al. (US Patent 10,842,205 B2), hereinafter Lee.
Regarding claims 7 and 17, Ein in view of Chen teaches the device of claim 1 and the method of claim 13 (as shown above). Although Ein discloses that a TE device depends on hot surface temperature and cold surface temperature ([0081]), Ein and Hong, alone or in combination, fail to teach wherein the device is configured to generate a cold side having a temperature in a range of about 5 °C – about 35 °C.
However, Lee teaches an apparel thermoregulatory system for actively cooling or heating a wearer using thermoelectric modules (i.e. Peltier device) wherein the device is configured to generate a cold side having a temperature in a range of about 5 °C – about 35 °C (Column 13, lines 32-33: “to maintain the cool side of each TEM between 10° C. and 20° C. when the TEMs are used for cooling.”, Column 13, lines 52-56: “And a maximum temperature of 40° C. may be set for the cold side of the TEM to avoid burning the wearer's skin. A minimum temperature of, for instance, 5° C. may be set for the cold side of the TEM to avoid freezing the wearer's skin”).
Although Lee does not explicitly teach these ranges, it would be obvious to one of ordinary skill in the art to use values within these ranges because Lee’s ranges are shown to be effective and they overlap heavily with the applicant’s ranges, therefore discovering the optimum or workable ranges of a result effective variable involves only routine skill in the art. In re Aller, 105 USPC 233.
It would have been prima facie obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Ein and Chen to incorporate the teachings of Lee to have the device configured to generate a cold side having a temperature in a range of about 5 °C – about 35 °C, as these prior art references are directed wearable thermoelectric devices.

One would be motivated to do this as this temperature range avoids freezing or burning the skin, as recognized by Lee (Column 13, lines 32-56).
Regarding claim 9, Ein in view of Chen teaches the device of claim 1 (as shown above). Although Ein discloses that a TE device depends on hot surface temperature and cold surface temperature ([0081]), Ein and Hong, alone or in combination, fail to teach wherein the device is configured to generate a cold side having a temperature in a range of about 18 °C – about 24 °C.
However, Lee teaches an apparel thermoregulatory system for actively cooling or heating a wearer using thermoelectric modules (i.e. Peltier device) wherein the device is configured to generate a cold side having a temperature in a range of about 18 °C – about 24 °C (Column 13, lines 32-33: “to maintain the cool side of each TEM between 10° C. and 20° C. when the TEMs are used for cooling.”, Column 13, lines 52-56: “And a maximum temperature of 40° C. may be set for the cold side of the TEM to avoid burning the wearer's skin.
