Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
5.Claims 12, 24, 10, 22, 34, and 4, 9, 16, 21, 28, 33, are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor, or for pre-AIA the applicant regards as the invention.
Claim 12 recites the limitation "the safety switch" in line 1. There is insufficient antecedent basis for this limitation in the claim. It is unclear claim 12 should depend on claim 11, so that the safety switch will have antecedent basis or claim 12 should depend on claim 1 and should be modified as “a safety switch.” For examination purpose, “the safety switch” in claim 12 is interpretated as “a safety switch.”
Claim 24 recites the limitation “the safety switch" in line 1. There is insufficient antecedent basis for this limitation in the claim. It is unclear claim 23 should depend on claim 11, so that the safety switch will have antecedent basis or claim 12 should depend on claim 13 and should be modified as “a safety switch.” For examination purpose, “the safety switch” in claim 24 is interpretated as “ a safety switch.”
Claim 10, claim 22, claim 34 recites “prevent charging of the internal battery from the DC port if the DC port is connected to the vehicle battery with an incorrect polarity.” It is unclear how could DC port is connected to the vehicle battery with an incorrect polarity, since DC port is (fixed) part of vehicle and always connects to the vehicle battery the same way. For examination purpose, the limitation has been interpretated as “prevent charging of the internal battery from the DC port if the USB connector is connected to the vehicle battery with an incorrect polarity.
The term “low power charging mode” in claims 4, 9, 16, 21, 28, 33 is a relative term which renders the claim indefinite. The term “low power” is not defined by the claim, the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably apprised of the scope of the invention. For examination purpose, the low power charging mode has been interpretated charging mode at any power level.
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 of this title, 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.

Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the battery charging system of claim 30, to operate at a high power charging mode when the detected voltage of the vehicle battery is above a minimum threshold voltage level and when the detected temperature of the internal battery is below a maximum threshold temperature level, as taught by Wu , in order to enable a high power fast charging ([0046][0047]) the battery but not to overheat the battery.
With regard to claim 32, the combination of Nook and Chen and Wu teaches all the limitations of claim 31, Chen teaches charging power is controlled at least in part by disabling the high power charging mode when the detected voltage of the vehicle battery is below the minimum threshold voltage level (detected voltage too low, below the normal range, automatically switch to output low current mode[0033]) or the detected temperature of the internal battery is above the maximum threshold temperature level.
8. Claims 12, 24, 35 are rejected under 35 U.S.C. 103 as being unpatentable over Nook(WO2016003471A1) and Chen (CN-206442135-U) in further view SALORANTA (US20170005509A1)
With regard to claim 12, the combination of Nook and Chen teaches all the limitations of claim 1, but not the safety switch is controlled by the USB driver based on a determination of whether the USB connector is attached to a compatible jump starter device.
However, Saloranta teaches the safety switch is controlled by the USB driver based on a determination of whether the USB connector is attached to a compatible jump starter device (.[0025]the battery charger 100 switches itself on automatically only when …. an USB OTG-compatible rechargeable device 130.[0034] the connected device is in an ‘off’ state, or the device is not USB OTG compatible 204 NO, the battery charger will not switch on, and Nook teaches about the USB connector attached to the jump starter device )
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the battery charging system of claim 1, to configure the safety switch to be controlled by the USB driver based on a determination of whether the USB connector is attached to a compatible jump starter device, as taught by Saloranta, in order to remove the risks of battery charger ‘s malfunction by using compatible device [0005]
With regard to claim 24, the combination of Nook and Chen teaches all the limitations of claim 13, but not the safety switch is controlled by the USB driver based on a determination of whether the USB connector is attached to a compatible jump starter device.
However, Saloranta teaches the safety switch is controlled by the USB driver based on a determination of whether the USB connector is attached to a compatible jump starter device (.[0025]the battery charger 100 switches itself on automatically only when …. an USB OTG-compatible rechargeable device 130.[0034] the connected device is in an ‘off’ state, or the device is not USB OTG compatible 204 NO, the battery charger will not switch on, and Nook teaches about the USB connector attached to the jump starter device )
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the battery charging system of claim 13, to configure the safety switch to be controlled by the USB driver based on a determination of whether the USB connector is attached to a compatible jump starter device, as taught by Saloranta, in order to remove the risks of battery charger ‘s malfunction by using compatible device [0005]
With regard to claim 35, the combination of Nook and Chen teaches all the limitations of claim 25, but not preventing charging of the internal battery from the DC port based on a determination that the USB connector is attached to an incompatible jump starter device.
However, Saloranta teaches preventing charging of the internal battery from the DC port based on a determination that the USB connector is attached to an incompatible jump starter device. (.[0025]the battery charger 100 switches itself on automatically only when …. an USB OTG-compatible rechargeable device 130.[0034] the connected device is in an ‘off’ state, or the device is not USB OTG compatible 204 NO, the battery charger will not switch on, and Nook teaches about the USB connector attached to the jump starter device )
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the battery charging system of claim 13, to prevent charging of the internal battery from the DC port based on a determination that the USB connector is attached to an incompatible jump starter device., as taught by Saloranta, in order to remove the risks of battery charger ‘s malfunction by using compatible device [0005]
Conclusion
9. The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
Mattos (US20190288532A1) teaches that Techniques for control of power switches in a USB Power Delivery (USB-PD) system
