Regarding claim 2, Reinstein discloses the portable skin cooling device according to claim 1, characterized in that the thermoelectric module (thermoelectric (TE) module 14) comprises a thermoelectric cooler (fig.1; cool surface 3, see also [0067]). Regarding claim 3, Reinstein discloses the portable skin cooling device according to claim 2, characterized in that the thermoelectric module (thermoelectric (TE) module 14) comprises one or multiple thermoelectric coolers arranged by stacking cold and hot surfaces or in a planar array (fig.1, see also [0067]). Regarding claim 4, Reinstein discloses the portable skin cooling device according to claim 1, further comprising a cooling temperature sensor, the cooling temperature sensor being located inside the housing (electronic controller 33) and connected to the PCB board (electronic controller 33), wherein the cooling temperature sensor is used to monitor temperature data of the cooling head ( cool plate 13) and feed back to the central control module (fig.2, see also [0068]). Regarding claim 5, Reinstein discloses the portable skin cooling device according to claim 1, characterized in that the housing (fig.2) is provided with a heat sink module (fig.1; heat sink 12, see also [0066]), the thermoelectric module (thermoelectric (TE) module 14) comprises a cooling surface (cool side 1) and a heating surface (hot side 2), and the heat sink module is connected to said heating surface (fig.1). Claim Rejections - 35 USC § 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claims 6 rejected under 35 U.S.C. 103 as being unpatentable over Reinstein (US 2008/0300529) in view of KIM (US 2021/0113365). Regarding claim 6, Reinstein the portable skin cooling device according to claim 5, characterized in that the heat sink module comprises a heat pipe (fig.1, see also [0068]), connected to the heating surface of the thermoelectric power source [0068] fixed inside the housing (fig.2). However, Reinstein does not disclose a phase change material sealed inside the heat pipe. Arnold teaches a medical cooling device including a cooling medium configured to cool a target region through thermal contact with the target region (abstract). The device includes heat transfer medium 116 may connect the cooling generator 113 and the heat dissipation unit 114 to transfer the heat of the cooling generator 113 to the heat dissipation unit 114. The heat transfer medium 116 may comprise a heat pipe or a vapor chamber and may include a pipe body and phase change material (PCM) provided inside the pipe body. The pipe body may be made of material having the high thermal conductivity so as to effectively transfer the heat from the cooling generator 113 that is in contact with the heat transfer medium 116 to the PCM therein. The PCM is the material that is able to store a great amount of thermal energy or release the stored thermal energy through the phase change . Therefore, it would have been obvious to one of ordinary skill in the art at the time the Application was effectively filed to modify as taught by Reinstein with heat pipe that includes phase changing material as taught by KIM for the purpose of effective heat transfer. Claim 7 is rejected under 35 U.S.C. 103 as being unpatentable over Reinstein (US 2008/0300529) in view of KIM (US 2021/0113365) in further view of Schaefer (US 2016/0022477). Regarding claim 7, Reinstein/ KIM does not disclose further comprising a heat sink module temperature sensor, said heat sink module temperature sensor fixed inside the housing and connected to the central control module, said heat sink module temperature sensor used to monitor the temperature of the heat sink module and feed back to the central control module. Schaefer teaches treatment methods for providing thermal contrast therapy, and systems for providing and managing thermal contrast therapy treatments. Schaefer further teaches the temperature of the heat sink may be monitored via heat sink temperature sensor 160. Therefore, it would have been obvious to one of ordinary skill in the art at the time the Application was effectively filed to modify as taught by Reinstein/ KIM with heat sink module temperature sensor as taught by Schaefer for the purpose of monitoring the temperature. Claims 9-10 are rejected under 35 U.S.C. 103 as being unpatentable over Reinstein (US 2008/0300529) in view of Ella (US 2003/0032900). Regarding claim 9, Reinstein does not disclose the portable skin cooling device according to claim 1, further comprising LED light therapy module and radio frequency therapy electrodes and further comprising electrotherapy electrodes, said electrotherapy electrodes fixed on the surface of the housing and connected to the central control module, said electrotherapy electrodes used for electrotherapy. Ella teaches the system includes a portable control-and-power console and a light-weight portable device having a plurality of spouts, designed for different portions of the body, and comprising different features. The different features are adapted for different modes of therapy, such as suction massage therapy, warming light therapy, UV light therapy, LLLT, ultrasound therapy, pulsating magnetic field therapy, constant magnetic field therapy, electrostimulation therapy, cooling-diode therapy, and warming-diode therapy (abstract). The system includes cooling-diode therapy and an electrode pair, for applying a electrostimulation therapy [0079]. Therefore, it would have been obvious to one of ordinary skill in the art at the time the Application was effectively filed to modify as taught by Reinstein light and electrode therapy as taught by Ella for the purpose of providing multiple therapy with one device.
