Re claim 10: Tomioka discloses a printed circuit board (PCB) (24 in fig. 3; para. 0018; fig. 7 is the embodiment referred to in this rejection but the elements of fig. 3 are mentioned because they are not shown in fig. 7 but para. 0038 states that the embodiment of fig. 7 includes all of fig. 3 other than wick 52; also, para. 0040 mentions that 51 can be a device with an angle that varies such as tablet or mobile information terminal) comprising: (a) at least a first heat generating component (a right 25 in fig. 3; para. 0018) mounted to the PCB at a first location (right location in fig. 3) ; (b) at least a second heat generating component (a middle 25 in fig. 3; para. 0018) mounted to the PCB at a second location (middle location in fig. 3) different than said first location (fig. 3) (c) at least one heat pipe comprising a closed pipe (32 in fig. 3 is closed pipe; para. 0020) comprising: (i) a condenser section (42 in fig. 3; para. 0022) in thermal communication with cooling fluid located outside of said heat pipe (42 is in thermal communication with air that flows through 33 which is outside pipe 32 in fig. 3) , Tomioka does not explicitly disclose (ii) a first evaporator section comprising a first reservoir containing liquid refrigerant in heat transfer contact with said first heat generating component; (iii) a first liquid flow path leading a first portion of liquid refrigerant condensed in said condenser section to said reservoir in said first evaporator section; (iii) at least a second evaporator section comprising a second reservoir at a location along said heat pipe different than said first reservoir and containing a second portion of liquid refrigerant in heat transfer contact with said at least said second heat generating component; and (iv) at least a second liquid flow path leading said second portion of liquid refrigerant condensed in said condenser section to said reservoir in said second evaporator section.

Re claim 20: The modified Tong does not explicitly disclose wherein said 5G chip is located in a telecommunications device. Lee discloses wherein said 5G chip is located in a telecommunications device (5g chipset 240 of fig. 4 is mounted to the rear surface of PCB 221b of mobile terminal 100 in fig. 2; 6 th para. of page 46) . Thus 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 method of the modified Tong wherein said 5G chip is located in a telecommunications device as taught by Lee, in order to add 5G connectivity to the telecommunications device . Conclusion 07-96 AIA The prior art made of record and not relied upon is considered pertinent to applicant's disclosure : US 2017/0067701 - is considered pertinent because this reference describes a mobile device with components on a PCB with thermal conductor running across it. US 2015/0216081 - is considered pertinent because this reference describes a mobile device with a component on a PCB with a heat pipe running vertically. US 2016/0088769 - is considered pertinent because this reference describes a mobile device with components on a PCB with a heat pipe connecting all of them.
