Office Action

§102 §112
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. 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 appl icant regards as his invention. Claim 5 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 5 recites the limitation “The lithium ion secondary battery according to claim 1” in lines 1-2. There is insufficient antecedent basis for this limitation in the 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. Claim(s) 1 and 5 is/are rejected under 35 U.S.C. 102 (a)(1) as being anticipated by Hisashi et al (JP2021027044) . Regarding claim 1, Hisashi teaches an all-solid-state battery comprising an interlayer solid electrolyte layer 3A located between a positive electrode active material layer 1B; a negative electrode active material layer 2B; and an outermost solid electrolyte layer 3B, respectively having thickness of 0.5-20 µm and 20-100µm; and a material such as a perovskite type compound, a garnet type compound, or a nasicon type compound used for a solid electrolyte (0027-0031). Regarding claim 5, Hisashi teaches the solid electrolyte material to be a perovskite type compound, a garnet type compound, or a nasicon type compound (0027-0031). Allowable Subject Matter Claims 2-4 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Hisashi et al (JP2021027044) is considered to be the closest prior art and neither teaches nor renders obvious the inventions are described in claims 2-4.
