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) 11 & 16 is/are rejected under 35 U.S.C. 103 as being unpatentable over Okuno ‘112. In regards to claim 11, Okuno ‘112 disclose all the claimed limitations discussed above with respect to claim 11, except for wherein the redox active metal ion is present in the electrolyte at an amount of from 7 mole percent to 13 mole percent. However, Okuno ‘112 disclsoes that the amount of redox metal ions in the electrolyte is a result effective variable, particularly for reducing increasing the capacity capacitor ([0098]). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to construct the capacitor of Okuno ‘112 such that the redox active metal ion is present in the electrolyte at an amount of from 7 mole percent to 13 mole percent order to increasing the capacity of the capacitor, as taught by Okuno ‘112. Where the general conditions of a claim are disclosed in the prior art, discovering the optimum or workable ranges involves only routine skill in the art. In re Aller, 105 USPQ 233. In regards to claim 16, Okuno ‘112 disclose all the claimed limitations discussed above with respect to claim 16, except for wherein the redox active metal ion is present in the electrolyte at an amount of from 7 mole percent to 13 mole percent. However, Okuno ‘112 disclsoes that the amount of redox metal ions in the electrolyte is a result effective variable, particularly for reducing increasing the capacity capacitor ([0098]). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to construct the capacitor of Okuno ‘112 such that the redox active metal ion is present in the electrolyte at an amount of from 7 mole percent to 13 mole percent order to increasing the capacity of the capacitor, as taught by Okuno ‘112. Where the general conditions of a claim are disclosed in the prior art, discovering the optimum or workable ranges involves only routine skill in the art. In re Aller, 105 USPQ 233. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
