Office Action

§103
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 . 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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 09/17/2026 has been entered. Response to Amendment The amendment filed on 09/17/2026 is entered and acknowledged by the Examiner. Claim 1 has been amended. Claims 4, 5, 10, 12, and 18 have been canceled. Claims 1-3, 6-9, 11, 13-17, and 19 are currently pending in the instant application. The rejection of claims 1-3, 6-9, 11, 13-17, and 19 under 35 U.S.C. 103 as being unpatentable over Koyama (WO 2021201003 Al) in view of Lee (US 2015/0364766 A1) and further in view of Kim (US 2021/0005893 A1) is withdrawn in view of Applicant’s amendment. Priority Acknowledgment is made of applicant's claim for foreign priority based on an application filed in Republic of Korea on 12/23/2021. It is noted, however, that applicant has not filed a certified copy of the 10-2021-0186382 application as required by 37 CFR 1.55. Allowable Subject Matter Claims 1-3, 6-9, 11, 13-17, and 19 are allowed. The following is a statement of reasons for the indication of allowable subject matter: the claims, filed on 09/17/2026, have been carefully reviewed and searched. Currently, there is no prior art alone or in combination that teaches or fairly suggests a conductive material slurry comprising a dispersant comprises a weight ratio of (i) cellulose-based compound having a weight average molecular weight of 100,000 g/mol or less and (ii) a conductive polymer having a weight average molecular weight of 50,000 g/mol to 200,000 g/mol is 1:0.25 to 1:2 as required in amended claim 1. Therefore, amended claim 1 is allowable over the prior art of record. Claims 2-3, 6-9, 11, 13-17, and 19 directly or indirectly depend from claim 1 and are allowable based on their dependencies.
