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 .
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 1-20 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.
Independent claim 1 requires “providing a parallel electrical circuit having a first battery unit and a first electrical contactor disposed in a first leg of the parallel electrical circuit, a second battery unit and a second electrical contactor disposed in a second leg of the parallel electrical circuit.” Requiring a parallel circuit can be interpreted in several different ways. It could mean that the circuit provided has “parallel” elements such as resistors and capacitors wired in the well-known “parallel” manner. It could also, as written, be interpreted to mean that the circuit provided must be wired into another circuit element in the well-known parallel fashion. Either interpretation of the claim as presented would be equally valid. Therefore, clarification is required. All subsequent dependent claims are also similarly rejected as being dependent upon a rejected base claim. Independent claims 13 & are similarly rejected along with any other dependent claims.
Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claims 1-2, 8-9, 11, 13, & 20 are rejected under 35 U.S.C. 102(a)(1) & (a)(2) as being anticipated by Klintberg et al (U.S. PGPub # 2024/0239238).

Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
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 3, 10, & 15 are rejected under 35 U.S.C. 103 as being unpatentable over Klintberg et al (U.S. PGPub # 2024/0239238)
Regarding claim 3, Klintberg teaches all elements of claim 2, upon which this claim depends.
Klintberg may not explicitly teach the first voltage sensor is in electrical communication with the first leg between a pole of the first battery and the first electrical contactor, and the second voltage sensor is in electrical communication with the second leg between a pole of the second battery and the second electrical contactor.
But it would have been obvious to one of ordinary skill in the art before the effective time of filing to have the first voltage sensor is in electrical communication with the first leg between a pole of the first battery and the first electrical contactor, and the second voltage sensor is in electrical communication with the second leg between a pole of the second battery and the second electrical contactor because all of the measurements made by the plurality of voltage sensors disclosed in paragraphs 0016, 0030, 0102-0136, and multiple places elsewhere in Klintberg would necessarily require that they all be connected to the listed elements and other circuit elements so that the measurements listed could be made.
Regarding claim 10, Klintberg teaches all elements of claim 1, upon which this claim depends.
Klintberg may not explicitly teach the first voltage sensor is in electrical communication with the first leg between a pole of the first battery and the first electrical contactor, and the second voltage sensor is in electrical communication with the second leg between a pole of the second battery and the second electrical contactor.
But it would have been obvious to one of ordinary skill in the art before the effective time of filing to have the first voltage sensor is in electrical communication with the first leg between a pole of the first battery and the first electrical contactor, and the second voltage sensor is in electrical communication with the second leg between a pole of the second battery and the second electrical contactor because all of the measurements made by the plurality of voltage sensors disclosed in paragraphs 0016, 0030, 0102-0136, and multiple places elsewhere in Klintberg would necessarily require that they all be connected to the listed elements and other circuit elements so that the measurements listed could be made.
Regarding claim 15, Klintberg teaches all elements of claim 13, upon which this claim depends.
Klintberg may not explicitly teach the first voltage sensor is in electrical communication with the first leg between a pole of the first battery and the first electrical contactor, and the second voltage sensor is in electrical communication with the second leg between a pole of the second battery and the second electrical contactor.

Allowable Subject Matter
Claims 5, 7, 17, & 19 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
The following is a statement of reasons for the indication of allowable subject matter: the prior art listed does not anticipate alone or combine in an obvious manner to teach the invention claimed by applicant.
Regarding claim 5,
The method of claim 4, wherein the method further comprises determining a first contactor resistance by sensing a first leg current using a first leg current sensor, and dividing the first contactor voltage by the first leg current.
Regarding claim 7,
The method of claim 6, wherein the method further comprises determining a second contactor resistance by sensing a second leg current using a second leg current sensor, and dividing the second contactor voltage by the second leg current.
Regarding claim 17, Klintberg & Wang teach all elements of claim 16, upon which this claim depends.
Klintberg does not explicitly teach determining a first contactor resistance by sensing a first leg current using a first leg current sensor in line within the first leg, and dividing the first contactor voltage by the first leg current.
Regarding claim 19,
The method of claim 18, wherein the method further comprises determining a second contactor resistance by sensing a second leg current using a second leg current sensor in line within the second leg, and dividing the second contactor voltage by the second leg current.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. The prior art listed but not cited represents the previous state of the art and analogous art that teaches some of the limitations claimed by applicant. Specifically, U.S. PGPub # 2020/0271728 teaches, as he title indicates, measuring voltage differences between battery cells and obtaining battery cell voltages which mimics applicants claimed invention but not as precisely as Klintberg. Also, U.S. PGPub # 2016/0197499 teaches a similar set of voltage sensors in use of monitoring battery devices.
