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.
Claims 9, 16, and their depending claims are 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 9 recites the limitation "said anodal foil" in lines 7-8. There is insufficient antecedent basis for this limitation in the claim.
Claim 9 recites the limitation "an external leading terminal" in lines 8. It is unclear if this “external leading terminal” is the same as “a lead terminal” introduced in line 3. Furthermore, “the lead terminal” is re-introduced in line 10.
Claim 10 recites the limitation "the lead-out terminal" in line 2. There is insufficient antecedent basis for this limitation in the claim.
Claim 11 recites the limitation "the lead-out end side" in line 2. There is insufficient antecedent basis for this limitation in the claim. Furthermore, the Applicant has stated “the external leading terminal” in line 3. It is unclear if this is referring to the “lead terminal” or the “external leading terminal” of claim 9.
Claim 16 recites the limitation "the external leading terminal" in lines 7 and 8. There is insufficient antecedent basis for this limitation in the claim.
Claim 16 recites the limitation "the anodal side foil" in line 8. There is insufficient antecedent basis for this limitation in the claim.
Claim 16 recites the limitation "the anodal external leading terminal" in line 10. There is insufficient antecedent basis for this limitation in the claim.
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.
Claim(s) 9-14, 16-18, 20-21, 23 and 26 is/are rejected under 35 U.S.C. 103 as being unpatentable over Yukihiro et al. (JP2002083738A) in view of Yano et al. (US Publication 2012/0267161).
In re claim 9, Yukihiro discloses a solid electrolytic capacitor comprising an anode foil (1 – Figure 1, ¶28) with dielectric oxide film formed thereon (¶28), a lead terminal (5 – Figure 1, ¶28) connected to the anode foil (1 – Figure 1), a capacitor element including the anode foil and a solid electrolyte (¶28) formed within the capacitor element and comprising a conductive polymer (¶18-20) , wherein a coating layer (11 – Figure 2, ¶30) repealing a conductive polymer forming solution between said anodal foil and an external leading terminal (5, 6 – Figure 1, ¶30) is formed (¶14-15, ¶32-37). Yukihiro does not disclose the thickness of the coating layer is not less than 10 nm and more than 150 nm. However, Yukihiro discloses reducing the thickness of the resin layer to reduce unevenness on the surface of the electrode tab, and thus, resulting in improved leakage current characteristics (¶12, ¶14). ). It would have been obvious to a person having ordinary skill in the art to adjust the thickness of the coating layer to realize a device having desired leakage current and miniaturization characteristics per user specifications, since such a modification would have involved a mere change in the size of a component. A change in size is generally recognized as being within the level of ordinary skill in the art. In re Rose, 105 USPQ 237 (CCPA 1955).
Yukihiro does not disclose wherein the coating layer does not crack or peel when a load of up to about 10 MPa is applied to the surface of the lead terminal.
Yano discloses increasing the pierce strength and adhesion of the resin film (15 – Figure 2, ¶35) to prevent the occurrence of whiskers and peeling (¶35, ¶40). It would have been obvious to a person having ordinary skill in the art before the effective filing date of the invention to adjust the pierce strength and adhesion characteristics of the resin film, and thus mechanical strength in response to external loads, to achieve a device having a reduced occurrence of whiskers, since it has been held that discovering an optimum value of a result effective variable involves only routine skill in the art. In re Boesch, 617 F.2d 272, 205 USPQ 215 (CCPA 1980).
In re claim 10, Yukihiro in view of Yano discloses the solid electrolytic capacitor of claim 9, as explained above. Yukihiro further discloses wherein the coating layer (11 – Figure 2) is for med at least at a portion facing the anode foil (1 – Figure 2) of the lead-out terminal (¶32-33).

Yukihiro does not explicitly disclose the contact angle between the surface of the coating layer and the conductive polymer forming solution is 80° or more.

It would have been obvious to a person having ordinary skill in the art to adjust the wettability effect, and thus arrive at a desired contact angle, since it has been held that discovering an optimum value of a result effective variable involves only routine skill in the art. In re Boesch, 617 F.2d 272, 205 USPQ 215 (CCPA 1980).

an electrolyte formation step that immerses a solution forming a solid electrolyte (¶35) from the opposite face of the end face of the capacitor element (Figure 1) formed around the external leading terminal (5, 6 -Figure 2) (¶35)and derived by the external leading terminal connected to the anodal side foil (1 – Figure 1), following the wounding step (¶34-36),
