ALL-SOLID-STATE BATTERY

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 . Information Disclosure Statement The information disclosure statement filed 9/2/2026 fails to comply with the provisions of 37 CFR 1.97, 1.98 and MPEP § 609 because the office action issued from the Korean Patent Office was never submitted along with a translation into English. It has been placed in the application file, but the information referred to therein has not been considered as to the merits. Applicant is advised that the date of any re-submission of any item of information contained in this information disclosure statement or the submission of any missing element(s) will be the date of submission for purposes of determining compliance with the requirements based on the time of filing the statement, including all certification requirements for statements under 37 CFR 1.97(e). See MPEP § 609.05(a). Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 9/16/2026 has been entered. Claim Status This Office action is responsive to amendments and remarks filed on 9/16/2026. Claims 1, 15, 23 and 27 have been amended. Claims 9, 22, and 34 are canceled. Claims 1-8, 10-21, 23-33, and 35 are currently pending. Response to Arguments Applicant's arguments filed 9/16/2026 have been fully considered but they are not persuasive. Applicant amended the claims to include the limitation “a surface of the negative electrode layer which is directly connected with the negative terminal has a spiral shape.” The applicant then goes on to show how this limitation reads on the instant drawing. However, the term “directly connected” when applied to electrical connections is overly broad and can still be interpreted as a direct electrical connection which is explained in further detail under both the claim interpretation section and the rejection under 103 below. Claim Interpretation The term “directly connected” while being definite and therefore not a rejection under 112(b) when applied to electrical connections is overly broad and can be interpreted as a direct electrical connection. While it could also be interpreted as physically adjacent to or some other type of direct connection which is explained in further detail in the rejection under 103 detailed below it should also be noted that for the negative connection, the Fig-6C of LUNDSGAARD shows a current collector/conductor (22) strip, which is also a layer of the negative electrode, directly connected to the negative terminal . Claim Rejections - 35 USC § 103 The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. Claims 1-8, 10-12, 14-21, 23-25, 27-33 and 35 are rejected under 35 U.S.C. 103 as being unpatentable over US 4879190 A, LUNDSGAARD in view of US 20200006718 A1, IMAI provided in the IDS dated 6/2/2026.
