DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Status of Claims
This Office Action is in response to the application filed on 12/29/2025. Applicant amended claim 1,14, and 24. Claims 1-6, 14, and 19-29 are presently pending and are presented for examination.
Response to arguments
In regards to the rejection of Claim(s) 1,14 and 24 Applicant asserts:
Yi's Uo is not a "detection value." Yi's describes Uo as "the voltage at the voltage output end of the power adapter or mobile power supply" (Yi, [0063]), which represents a constant supply voltage parameter as acknowledged by the Office Action (see NFOA, p. 3), not a detected value.
And further asserts:
Examiner respectfully disagree. Using Broadest reasonable interpretation, in light of the specification, Examiner will interpret a first and second detection voltage value as determined voltages values at the power supply end of the charging cable.
As such as seen by the rejection of claims 1, 14 and 24, Yi teaches a first and second source voltage detection value of the first end of the charging cable (Fig. 3 and [0063] U0.
Although the applicant is entitled to be their own lexicographer, unless the Applicant set forth a special definition for the claim term the applicant does not provide a special definition for claim language “detected”. The claim term will be given its broadest reasonable construction "in light of the specification as it would be interpreted by one of ordinary skill in the art (MPEP 2111). The claim word “detect” used in its plain and ordinary meaning is “discover or identify the presence or existence of” as such, since Yi identifies “U0” as the value of the first end of the charging cable, Yi teaches “U0” as a detection voltage.
In regards to the rejection of Claim(s) 1,14 and 24 Applicant asserts:
Yi's Uo, mapped to the claimed constant first voltage value, does not disclose the claimed first and second source voltage detection values, each of which is different from the asserted first voltage value (Uo).
And further asserts:
Further, Yi does not suggest that two voltage values (i) detected at the power supply end of the cable and (2) different from the constant first voltage value (Uo) are used for calculating the asserted impedance value RS.
In regards to applicants remaining remarks:
Applicant remarks have been considered but are moot base on new grounds of rejection.
Specification
The disclosure is objected to because of the following informalities:
Claims 1-6, 14, and 19-29 recite “first voltage” lack antecedent basis to the specification.
Appropriate correction is required.
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.
Claims 1-6, 14, and 19-29 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 applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Claims 1, 14 and 24 recites “receiving, by the electronic device, first electric energy from the power supply device through the charging cable, and obtaining a first source voltage detection value of the first end of the charging cable and a first final voltage detection value of the second end of the charging cable, wherein a first voltage of the first electric energy is constant, the first source voltage detection value is different from the first voltage, and a first current of the first electric energy is a first current value; receiving, by the electronic device, second electric energy from the power supply device through the charging cable, and obtaining a second source voltage detection value of the first end of the charging cable and a second final voltage detection value of the second end of the charging cable, wherein a second voltage of the second electric energy is the same as the first voltage of the first electric energy, the second source voltage detection value is different from the first voltage” which is unclear.
It is unclear what is the distinction between “the first source voltage detection value” and “the second source voltage detection value”, “a first voltage”, “a second voltage” “a second final voltage detection value” and “a first final voltage detection value”.
The specification (Fig. 1 and [0023]) identifies “the second source voltage detection value” and “the first source voltage detection value” as the voltage at the power supply device (“Vadp_detection_yA” and “Vadp_detection_xA” respectively). The specification also identifies the “a second final voltage detection value” and “a first final voltage detection value” as the voltage at the electronic device.
However claims 1, 14 and 24 recites “the first source voltage detection value is different from the first voltage” and “wherein a second voltage of the second electric energy is the same as the first voltage of the first electric energy” suggests that the claimed “first voltage” and “second voltage” is not the voltage of the at the power supply device.
Additionally, as described above from the specification objection, the disclosure does not described the first and second voltage and therefore the first and second voltage lacks antecedent basis to the specification.
Additionally, based on the Applicants remarks which states “Further, Yi does not suggest that two voltage values (i) detected at the power supply end of the cable and (2) different from the constant first voltage value (Uo) are used for calculating the asserted impedance value RS” suggests that the first and second voltage are used to calculate the impedance value. However, the specification ([0023]) and claim 1 claims that the first and second final voltage detection value (and not the first and second voltage as suggest by applicants’ remarks) is used to calculate the impedance value of the charging cable.
Based on BRI in light of the specification ([0065] …. an exact value of Vadp is 10.5 V, a detection value of Vadp is 10.4 V), Examiner will interpret the claimed “first voltage” and “second voltage” as an expected or rated voltage.
Claims 2-6, and 19-23 and 25-29 are included in this rejection based on their dependence on claims 1, 14 and 24.

In regards to requesting the power supply device to indicate the second source voltage detection value of the first end of the charging cable to the electronic device.
However, since Yi electronic device uses the second source voltage detection value of the first end of the charging cable (U0) to calculate loop equations (Fig. 3 and [0063], it would be obvious to one of ordinary skill in the art for Yi’s electronic device request the power supply device to indicate the second source voltage detection value, in order for Yi to accurately calculate its loop equations which are then used to calculate the impedance ([0063]-[0067]).
In regards to sending, by the electronic device, a second request to the power supply device after obtaining the first source voltage detection value and the first final voltage detection value. Absent an objective showing of criticality with regards to the whether to send the second request after obtaining the first source voltage detection value and the first final voltage detection value, it would have been obvious to one of ordinary skill in the art to send the second request of providing the second electric energy and indicating the second source voltage detection value as it would have been obvious to try.
Specifically, since Yi calculates the equivalent series impedance using the first and second electric energy (i.e.RS=(U1-U2)/(I2-I1)), then either one of the first or the second electric energy must be provided first. Therefore one of ordinary skill in the art can see one of the request of providing the first or the second electric energy and their corresponding first and second source voltage detection value will happen after the other.
Claims 5, 22, and 28 is/are rejected under 35 U.S.C. 103 as being unpatentable over Yi (CN106546822) in view of Iwata (US 20180069393) in view of Jung (US 20170126023).
As to claim 5, 22 and 28, Yi in view of Iwata teaches the method according to claim 1 and teaches the electronic device according to claim 14 and teaches the non-transitory computer-readable storage medium according to claim 24.
Yi does not disclose/teach wherein an absolute value of a difference between the first current value and the second current value is less than two times the first current value, and the absolute value of the difference between the first current value and the second current value is less than two times the second current value.
Jung teaches an absolute value of a difference between the first current value and the second current value is less than two times the first current value, and the absolute value of the difference between the first current value and the second current value is less than two times the second current value ([0054] the start step determined in operation 112 is an initial charging step of the fast charging mode. [0072]..the next four charging steps correspond to the four charging steps of the fast charging mode in Table 1 above with charging currents of 4.125 A, 3.3 A, …. Therefore the difference between absolute values of 4.125 A and 3.3A are less than two times 4.125 A and 3.3A).
It would have been obvious to a person of ordinary skill in the art to modify the method of Yi wherein an absolute value of a difference between the first current value and the second current value is less than two times the first current value, and the absolute value of the difference between the first current value and the second current value is less than two times the second current value in order to prevent a reduction in battery life by dynamically adjusting the battery charging steps based on the measured battery voltage.
