§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 . 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—4 and 15—18 is/are rejected under 35 U.S.C. 103 as being unpatentable over Dou, et al. (WO 2021/042990 A1). Regarding claim 1, Dou. et al. teach an electrochemical apparatus (paragraph 0003), comprising: a positive electrode (paragraph 0192), a negative electrode (paragraph 0193), and an electrolyte (paragraph 0194); wherein the positive electrode comprises a positive electrode current collector (paragraph 0192) and a positive electrode active material layer formed on the positive electrode current collector (paragraph 0192, and the positive electrode active material layer comprises a positive electrode active material (paragraph 0192), wherein the positive electrode active material including a transition metal layer of a lithium nickel cobalt manganese oxide includes a doping element in particles of the positive electrode active material (paragraph 0007); the electrolyte comprises a dinitrile compound (paragraph 0162; examiner notes Dou, et al. teach succinonitrile, adiponitrile, or glutaronitrile as additives to the electrolyte solution). Dou, et al. do not specifically teach an example wherein the positive electrode active material comprises lithium nickel cobalt manganate containing aluminum, zirconium, and tungsten (Table 1; examiner notes Dou, et al. teach an example where the lithium nickel cobalt manganate doping elements are zirconium and tungsten in example 4).

Prior art which teaches a range within, overlapping, or touching the claimed range anticipates if the prior art range does not substantially deviate from the claimed range. In re Wertheim, 541 F.2d 257, 191 USPQ 90 (CCPA 1976) (anticipation found even where prior art range was not identical to claimed ranges); see also MPEP 2144.05 and MPEP 2131.03.

Wang, et al. teach an electrochemical device (paragraph 0002) containing an electrolyte comprising a dinitrile compound wherein based on a total weight of the electrolyte a weight percentage of the dinitrile compound (claim 1). Wang, et al. motivation to add the dinitrile compound to the electrolyte is to inhibit the increase in DC internal resistance of the electrochemical device (paragraph 0005) and achieves high-capacity density and has excellent cycle and storage performances (paragraph 0015). Duo, et al. and Wang, et al. teach an electrochemical device with electrolyte comprising a dinitrile compound (adiponitrile and glutaronitrile) and trinitrile (hexanetrinitrile) compound with a motivation of improving higher capacity density and long cycle performances. Therefore, it would have been obvious to one of ordinary skill in the art at the time the invention was filed to configure a electrochemical device with a mass based percentage of tungsten in the positive electrode active material taught by Duo, et al. with a mass based percentage of dinitrile compound in the electrolyte solution taught by Wang, et al. to create an electrochemical device with a higher energy density and good high-temperature cycle as claimed.
