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. 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) 10-11 & 15-17 is/are rejected under 35 U.S.C. 103 as being unpatentable over Miura ‘510 in view of FR1439148A hereafter referred to as Leroy. In regards to claim 10, Miura ‘510 discloses a lid assembly configured for closing a cell body (4 – fig. 1; [0059]) of a supercapacitor, the cell body comprising a bottom portion (4A – fig. 1; [0059]), a wall portion, and a top opening (fig. 1), the lid assembly comprising: an electrically insulating sealing member (5 – fig. 1; [0068]) and a current tab member according to claim 1 (see claim rejection above), wherein the sealing member and the current tab member are in contact with each other (fig. 1). Miura ‘510 fails to disclose wherein the sealing member includes a plurality of fluid openings, and the fluid openings and the contacting portions are configured such that irrespective of a relative orientation of the current tab member and the sealing member an equivalent of at least one fluid opening is unobstructed by the current tab member. Leroy disclose wherein the sealing member (3 – fig. 1) includes a plurality of fluid openings (12 – fig. 1), and the fluid openings in fluid communication with interior of the capacitor for allow for fluid transfer into expansion chambers during fluid expansion preventing leaks. It would have been obvious to one of ordinary skill in the art prior to the effective filing date of the claimed invention to form fluid openings that are unobstructed to the fluid of the capacitor as taught by Leroy in the sealing member of Miura ‘510 to obtain a capacitor with improved protection from leaking In regards to claim 11, Miura ‘510 a modified by Leroy further discloses wherein the sealing member includes a sealing opening (5A – fig. 1 & 3; [0068] of Miura ‘510) that is defined by a circumferential sidewall and the terminal portion is inserted in the sealing opening such that a seal is formed between the terminal portion and the circumferential sidewall (fig. 1). In regards to claim 15, Miura ‘510 a modified by Leroy further discloses cell body kit-of-parts for forming a cell body of a supercapacitor, the kit-of-parts comprising: a cell body (4 – fig. 1; [0059] of Miura ‘510) having a bottom portion (4A – fig. 1; [0067] of Miura ‘510), a wall portion (4K – fig. 1; [0067] of Miura ‘510), and a top opening ([0067] of Miura ‘510; and a lid assembly according to claim 10 (see claim 10 rejection above), configured to be insertable into the top opening to form a closed off cell interior (fig. 1 of Miura ‘510). In regards to claim 16, Miura ‘510 discloses an energy storage cell comprising: a cell body (4 – fig. 1; [0059]) having a bottom portion (4A – fig. 1; [0059]), a wall portion (4l – fig. 1; [0067]), a top opening (fig. 1; [0067), and at least one of the following feature groups: a) a lid assembly configured to be insertable into the top opening to form a closed off cell interior, the lid assembly comprising an electrically conductive lid member and an electrically insulating sealing member; and an electrode assembly configured for storing electrical energy that is disposed in the cell interior, the electrode assembly having a current tab member according to claim 1; or b) a lid assembly comprising: an electrically insulating sealing member (5 – fig. 1 & 3; [0068]) and the current tab member (see claim 1 rejection above), wherein the sealing member and the current tab member are in contact with each other (fig. 1), and an electrode assembly configured to store electrical energy that is disposed in the cell interior, the electrode assembly having a current tab member ([0062-0063]). Miura ‘510 fails to disclose wherein the sealing member includes a plurality of fluid openings, and the fluid openings and the contacting portions are configured such that irrespective of a relative orientation of the current tab member and the sealing member an equivalent of at least one fluid opening is unobstructed by the current tab member. Leroy disclose wherein the sealing member (3 – fig. 1) includes a plurality of fluid openings (12 – fig. 1), and the fluid openings in fluid communication with interior of the capacitor for allow for fluid transfer into expansion chambers during fluid expansion preventing leaks. It would have been obvious to one of ordinary skill in the art prior to the effective filing date of the claimed invention to form fluid openings that are unobstructed to the fluid of the capacitor as taught by Leroy in the sealing member of Miura ‘510 to obtain a capacitor with improved protection from leaking In regards to claim 17, Miura ‘510 a modified by Leroy further discloses wherein the energy storage cell comprises a supercapacitor ([0059]). Allowable Subject Matter Claim(s) 6 & 12-14 is/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. The following is a statement of reasons for the indication of allowable subject matter: The prior art does not teach or suggest (in combination with the other claim limitations) wherein each contacting portion includes a tab welding portion that extends in a radial direction, and wherein each tapered heat sink portion includes a notch that continuously transitions into the tab welding portion (claim 6), wherein the sealing opening includes a tapered sealing portion that expands downward, and wherein the tapered sealing portion is in contact with the heat sink portion (claims 12-13), wherein the lid assembly comprises an electrically conductive lid member, wherein the lid member and the sealing member are configured to cooperatively form an expansion chamber that is arranged between the lid member and the sealing member, and wherein the expansion chamber is fluidly connectable to an interior of the cell body, and the current tab member is in contact with the sealing member and electrically insulated from the lid member by the sealing member (claim 14). Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
