The following is a statement of reasons for the indication of allowable subject matter: The prior art fails to teach, disclose, or suggest, in combination with other limitations recited in dependent Claim 6: “wherein the fire extinguishing pipe comprises a fixing member protruding from a side surface of the fire extinguishing pipe facing the at least one battery module and extending into the rigid reinforcement portion.”. Regarding Claim 6, in reference to the battery rack of Jung as applied to Claim 2 above, Jung further discloses wherein the fire extinguishing pipe comprises a fixing member protruding from a side surface of the fire extinguishing pipe facing the at least one battery module (See #135 in Fig. 11). However, Jung does not disclose wherein the fixing member extends into the rigid reinforcement portion as claimed (See Annotated Fig. 3, the rigid reinforcement portion RRP has nozzles on both sides but no nozzles go through RRP such that none of the fixing members #135 extend into the rigid reinforcement portion). One having ordinary skill in the art before the effective filing date of the claimed invention would not be motivated to reconfigure the battery rack of Jung such that the fixing member extends into the rigid reinforcement portion as required by Claim 6, as there is no apparent benefit to making such a modification and making such a modification would change the overall configuration of the battery rack of Jung. Furthermore, there is no prior teaching in Jung or other prior art that indicates that making such a modification would be an obvious design choice without utilizing improper hindsight. The prior art also fails to teach, disclose, or suggest, in combination with other limitations recited in dependent Claim 8: “wherein the at least one nozzle faces the rigid reinforcement portion and is configured to be connected to the at least one battery module by passing through the rigid reinforcement portion”. Regarding Claim 8, in reference to the battery rack of Jung as applied to Claim 2 above, Jung does not disclose wherein the at least one nozzle faces the rigid reinforcement portion and is configured to be connected to the at least one battery module by passing through the rigid reinforcement portion (See Annotated Fig. 3 and Annotated Fig. 10, the rigid reinforcement portion RRP has nozzles on both sides but no nozzles go through RRP, thus none of the nozzles face RRP or pass through RRP). One having ordinary skill in the art before the effective filing date of the claimed invention would not be motivated to reconfigure the battery rack of Jung such the at least one nozzle faces the rigid reinforcement portion and is configured to be connected to the at least one battery module by passing through the rigid reinforcement portion as required by Claim 8, as there is no apparent benefit to making such a modification and making such a modification would change the overall configuration of the battery rack of Jung. Furthermore, there is no prior teaching in Jung or other prior art that indicates that making such a modification would be an obvious design choice without utilizing improper hindsight. Response to Arguments Applicant's arguments filed 8/12/2026 have been fully considered but they are not persuasive. Regarding Claim 1 being rejected under 35 U.S.C. 102(a)(1) as being anticipated by Jung, applicant argues that Jung does not disclose the rigid reinforcement portion as now claimed. This argument is not found persuasive. In accordance with MPEP 2111.01, during examination the claims must be interpreted as broadly as their terms reasonably allow. In re Prater, 415 F.2d 1393, 1404-05, 162 USPQ 541, 550-51 (CCPA 1969). The portion RRP shown in Annotated Fig. 3 is equivalent to a rigid reinforcement portion that extends horizontally on the first side of the rack frame to reinforce a rigidity of the rack frame, such that a top edge of the rigid reinforcement portion is positioned below a top edge of the support and a bottom edge of the rigid reinforcement portion is positioned above a bottom edge of the support as claimed. Therefore, the disclosed battery rack of Jung still reads on a broadest reasonable interpretation of Claim 1, and Claim 1 remains rejected under 35 U.S.C. 102(a)(1). Conclusion THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
