Office Action

§102
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 . Election/Restrictions Applicant’s election without traverse of Group I, claims 1-3 and 5 in the reply filed on 9/16/26 is acknowledged. Claim 4 is withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected method, there being no allowable generic or linking claim. 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. The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claims 1-3 and 5 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Ogata (US 2017/0077497 A1). Ogata discloses a battery apparatus comprising: a negative electrode, a positive electrode, and an electrolyte (paragraph 108), wherein the electrolyte is a sulfide solid electrolyte (paragraph 131) and the negative electrode comprises an active material comprising silicon and a polymer (paragraph 61), wherein the polymer is polyvinylidene fluoride (paragraph 69). It should be noted that no molded body is positively recited nor is the electrolyte mixed with the active material in these apparatus claims. The instant specification clearly states the claimed property is that of the polymer (paragraph 18) and that polyvinylidene fluoride is such a polymer (paragraph 17). Something which is old does not become patentable upon the discovery of a new property. See MPEP 2112 I.
