The following title is suggested: BATTERY MANAGEMENT COMMUNICATION SYSTEM INCLUDING SEGMENT COMMUNICATION UNITS CORRESPONDING TO RESPECTIVE BATTERY CELL GROUPS.
Applicant is reminded of the proper language and format for an abstract of the disclosure.
The abstract should be in narrative form and generally limited to a single paragraph on a separate sheet within the range of 50 to 150 words in length. The abstract should describe the disclosure sufficiently to assist readers in deciding whether there is a need for consulting the full patent text for details.
The language should be clear and concise and should not repeat information given in the title. It should avoid using phrases which can be implied, such as, “The disclosure concerns,” “The disclosure defined by this invention,” “The disclosure describes,” etc. In addition, the form and legal phraseology often used in patent claims, such as “means” and “said,” should be avoided.
The abstract of the disclosure is objected to because it contains legal phraseology such as “said”. A corrected abstract of the disclosure is required and must be presented on a separate sheet, apart from any other text. See MPEP § 608.01(b).
Claim Rejections - 35 USC § 102
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.

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.
Claim(s) 3 is/are rejected under 35 U.S.C. 103 as being unpatentable over KIM as applied to claims 1-2, 4-8, 10, and 12-20 above, and further in view of ERHART (EP3471186; cited on IDS with date 5/12/2023; copy provided by Applicant).
Regarding claim 3, KIM discloses the battery management communication system as applied to claim 2, but fails to disclose the at least one battery charge controller of the first group comprises a plurality of battery charge controllers, each of which being integrated with a respective one of the battery cells of the first group, and wherein the first segment communication unit is configured to communicate with said plurality of battery charge controllers via the first set of communication lines; wherein the at least one battery charge controller of the second group comprises a plurality of battery charge controllers, each of which being integrated with a respective one of the battery cells of the second group, and wherein the second segment communication unit is configured to communicate with said plurality of battery charge controllers via the first set of communication lines.
ERHART discloses the at least one battery charge controller of the first group comprises a plurality of battery charge controllers (70, Fig. 2), each of which being integrated with a respective one of the battery cells of the first group (10, Fig. 2), and wherein the first segment communication unit (90, Fig. 2) is configured to communicate with said plurality of battery charge controllers via the first set of communication lines (¶ 0036-0037). Providing a battery charge controller for a respective battery cell as disclosed in ERHART for the plurality of groups of KIM teaches the recitations the at least one battery charge controller of the second group comprises a plurality of battery charge controllers, each of which being integrated with a respective one of the battery cells of the second group, and wherein the second segment communication unit is configured to communicate with said plurality of battery charge controllers via the first set of communication lines.
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention was made to incorporate the plurality of battery charge controllers each corresponding to a respective battery cell of ERHART into the battery management communication system of KIM to produce an expected result of a battery management communication system including a plurality of battery charge controllers each corresponding to a respective battery cell. The modification would be obvious because one of ordinary skill in the art would be motivated to provide superior monitoring, protection, and/or cell balancing.
Claim(s) 9 and 11 is/are rejected under 35 U.S.C. 103 as being unpatentable over KIM as applied to claims 1-2, 4-8, 10, and 12-20 above, and further in view of SAKAI (US Pub. No. 2010/0111201).
Regarding claim 9, KIM discloses the battery management communication system as applied to claim 8, but fails to disclose the system includes an inductor between the first power line node and the first-group-positive node.
SAKAI discloses the system includes an inductor (26/L1, Fig. 3A) between [a first node] and [a second node] (inductor L1, which is part of element 26 in Figure 1, is located between nodes 18 and 28 as shown in Fig. 1; ¶ 0038-0039 discloses the inductor prevents a power line communication signal from propagating to an undesired part of the circuit). It would have been obvious to one of ordinary skill in the art to provide the inductor of SAKAI between the first power line node and the first-group-positive node of SAKAI for similar purposes/functionality.
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention was made to incorporate the inductor of SAKAI into the battery management communication system of KIM to produce an expected result of a battery management communication system including an inductor. The modification would be obvious because one of ordinary skill in the art would be motivated to control the propagation of the power line communication signals (SAKAI, ¶ 0004-0009) within the battery management communication system of KIM.
Regarding claim 11, KIM discloses the battery management communication system as applied to claim 8, but fails to disclose the system includes an inductor between the first-group-negative node and the second-group-positive node.
SAKAI discloses the system includes an inductor (26/L1, Fig. 3A) between [a first node] and [a second node] (inductor L1, which is part of element 26 in Figure 1, is located between nodes 18 and 28 as shown in Fig. 1; ¶ 0038-0039 discloses the inductor prevents a power line communication signal from propagating to an undesired part of the circuit). It would have been obvious to one of ordinary skill in the art to provide the inductor of SAKAI between the first-group-negative node and the second-group-positive node of SAKAI for similar purposes / functionality.
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention was made to incorporate the inductor of SAKAI into the battery management communication system of KIM to produce an expected result of a battery management communication system including an inductor. The modification would be obvious because one of ordinary skill in the art would be motivated to control the propagation of the power line communication signals (SAKAI, ¶ 0004-0009) within the battery management communication system of KIM.
