Office Action

§103 §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 applicant regards as his invention. Claim 11 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 11 recites “wherein the two tabs of the each electrode assembly protrude from the packaging shell in different directions” is unclear which tabs are being referred to here as claim 1 claims two sets of “two tabs”. Furthermore, there is insufficient disclosure to show how the tabs protrude in opposite directions as the instant Figures disclose all of the tabs that are not connected extending in the same direction. For purposes of examination the examiner is interpreting “wherein the two tabs of the each electrode assembly protrude from the packaging shell in different directions” to mean any structure where the nonconnected tabs are protruding in a different location that is not stacked as the connected tabs. Claim Rejections - 35 USC § 103 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 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claim(s) 1-20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Sano (JP2019145628, see Machine Translation for citations) (Provided in Applicant’s IDS filed on March 7th, 2023) Regarding Claim 1 & 15, Sano discloses an electrochemical apparatus (power storage device, [001]), comprising two electrode assemblies and a packaging shell, wherein the two electrode assemblies are respectively disposed in independent cavities in the packaging shell (electrode bodies-4a/4b are disposed in separate shells, Fig. 1, [0026]); Each electrode assembly comprises two tabs with opposite polarities (), wherein at least one tab of one electrode assembly is connected to one of two tabs of the other electrode assembly, and orthographic projections of the two connection tabs along a seal thickness direction Z overlap to form a tab overlapping region (Fig. 1, tab-50a and tab-52b are of opposite polarity and overlap, [0037]); and Sano does not directly disclose wherein the a ratio α of an overlapping width O1 of the two connected tabs to a width W1 of either of the two connected tabs satisfies 40%<α≤100%, wherein the overlapping width O1 is an overlapping width of the two connected tabs along a seal length direction X at an outer edge of a seal of the packaging shell viewed along the seal thickness direction Z; and the width W1 of the tab is a width of either of the two connected tabs along the seal length direction X at the outer edge of the seal of the packaging shell viewed along the seal thickness direction Z. However, the examiner notes that these limitations are relative dimension limitations. Furthermore, Sano discloses wherein the length and width of the current collector and the tabs can be adjusted ([0046]). Sano further discloses wherein the thickness of the leads can have a wide range of thicknesses ([0037]). In Gardnerv.TEC Syst., Inc., 725 F.2d 1338, 220 USPQ 777 (Fed. Cir. 1984), cert. denied, 469 U.S. 830, 225 USPQ 232 (1984), the Federal Circuit held that, where the only difference between the prior art and the claims was a recitation of relative dimensions of the claimed device and a device having the claimed relative dimensions would not perform differently than the prior art device, the claimed device was not patentably distinct from the prior art device. Therefore, absent a showing of criticality, it would be obvious to one of ordinary skill in the art using the disclosure of Sano to have wherein the a ratio α of an overlapping width O1 of the two connected tabs to a width W1 of either of the two connected tabs satisfies 40%<α≤100%, wherein the overlapping width O1 is an overlapping width of the two connected tabs along a seal length direction X at an outer edge of a seal of the packaging shell viewed along the seal thickness direction Z; and the width W1 of the tab is a width of either of the two connected tabs along the seal length direction X at the outer edge of the seal of the packaging shell viewed along the seal thickness direction Z.

However, the examiner notes that these limitations are relative dimension limitations. Furthermore, Sano discloses wherein the length and width of the current collector and the tabs can be adjusted ([0046]). Sano further discloses wherein the thickness of the leads can have a wide range of thicknesses ([0037]). In Gardnerv.TEC Syst., Inc., 725 F.2d 1338, 220 USPQ 777 (Fed.
