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 . Detail Action This office action is in response to the amendment filed on 3/11/2026. Claims 1-14 and 16-21 are pending. 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. Claim 7 recites the limitation "the periodic interval" in “the periodic interval is one day”. There is insufficient antecedent basis for this limitation in the claim. Claim 7 depends on claim 6, claim 6 recites “periodic intervals” instead of “periodic interval”. Claim 13 recite the limitation of “the user” in notifying the user”. There is insufficient antecedent basis for this limitation in the claim. 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. Claim(s) 1, 3, and 14 is/are rejected under 35 U.S.C. 103 as being unpatentable over Jiang (CN 210737443 U), Pillilli et al. (US 20210224061 A1) in view of Sayyed et al.

(WO 2011161778A1) Per claim 1, Jiang discloses updating software to a machine with rechargeable battery (pp. 6, discloses software update to machine vehicle with battery that can be charged) Jiang does not, however, Pillilli discloses determining that a software update exists for the software; ([0075], discloses an indication that a firmware update is available) (c) updating the software via remote flashing. ([0015], discloses access firmware code from storage 120 and have a flash image… since the firmware code 122 is in storage 120 that is outside/remote from 102 and is considered remote flashing.) Therefore, it would have been obvious to a person of ordinary skill before the effective filing date of the invention to incorporate the teachings of Pillilli into the teachings of A to include the limitation disclosed by Pillilli. The modification would be obvious to one of ordinary skill in the art to want to perform software update to fix bugs to introduce newer capabilities as suggested by Pillilli ([0002]) Jiang/Pillilli does not, however, Sayyed discloses (b) determining whether the rechargeable battery is connected to a charging module, wherein either: in an event that the rechargeable battery is connected to a charging module the method proceeds to step (c); or in an event that the rechargeable battery is not connected to a charging module, step (c) is delayed until the rechargeable battery is connected to a charging module; and ([0038], discloses battery health indicator related to firmware update risk…only performing firmware update when the information handling system is connected to AC power source, and therefore, the update is delayed until AC power source is connected.) Therefore, it would have been obvious to a person of ordinary skill before the effective filing date of the invention to incorporate the teachings of Sayyed into the teachings of Jiang/Pillilli to include the limitation disclosed by Sayyed. The modification would be obvious to one of ordinary skill in the art to want to reduce firmware update risk mitigating poor battery health condition as suggested by Pillilli([0038]) Jiang/Pillilli/Sayyed does not disclose, however, Murata discloses (d) preventing removal of the rechargable battery from the charging module via an interlock while updating the software.

([0086], discloses determining battery is fully charged and starting action of updating software. Since the battery can be fully charged, it is inherently disclosing a charging speed that minimally increase the battery charging level.) Therefore, it would have been obvious to a person of ordinary skill before the effective filing date of the invention to incorporate the teachings of Sakabibara into the teachings of Jiang/Pillilli/Sayyes/Murata to include the limitation disclosed by Sakabibara. The modification would be obvious to one of ordinary skill in the art to want to wait until the battery is fully charged before updating software to avoid issues.
