[0042]), wherein metal layers adjacent to each other in the plurality of metal layers are made of different kinds of metals (First region 90 composed of a copper-based metal, and a second region 92 comprised of aluminum metal [0042]), and second metal layer covers a peripheral end surface of a remaining metal layer among the plurality of metal layers ( (92) fig. 7(b)). Muroya does not explicitly disclose the flange portion is formed of a clad material. However in the same field of endeavor Tsunaki discloses a battery [Abstract] and teaches the negative electrode external terminal 105 is formed of a flat clad material in which an aluminum alloy portion 105a (first alloy portion) and a copper alloy portion 105b (second alloy portion) [0053], and further teaches the connection resistance may be reduced by terminal made of clad materials [0092]. It would have been obvious to one of ordinary skill in the art before the time the application was filed to modify Muroya with the clad materials of Tsunaki to reduce the connection resistance of the terminal. Modified Muroya does not explicitly disclose shaft portion includes an enlarged diameter portion formed between the flange portion and the outer surface of the case and spreading along the outer surface of the case; wherein the swaged portion sandwiches the peripheral edge portion of the through hole in the flange portion between the swaged portion and the enlarged diameter portion. Yamada discloses the shaft portion includes: an enlarged diameter portion (8a) formed between the flange portion and the outer surface of the case and spreading along the outer surface of the case (fig. 3). the swaged portion (8d) sandwiches the peripheral edge portion of the through hole in the flange portion (9a) between the swaged portion and the enlarged diameter portion (fig. 3). Yamada further teaches when a force is applied to terminal plate (9) with the above configuration it can prevent the damage and breakage of the connecting part of the negative electrode terminal plate 9 and the negative electrode terminal member 8. [0059] It would have been obvious to one of ordinary skill in the art before the time the application was filed to modify Muroya with the structure of Yamada to prevent damage to the electrode terminal plate and terminal. The product-by-limitations of claim 2, “clad material”, are not given patentable weight since the courts have held that patentability is based on a product itself, even if the prior art product is made by a different process (In re Thorpe, 227 USPQ 964, 1985). Moreover, a product-by-process limitation is held to be obvious if the product is similar to a prior art product (In re Brown, 173 USPQ 685, and In re Fessman, 180 USPQ 324). Claim 1 as written does not distinguish the product of the instant application from the product of the prior art. Response to Arguments Applicant's arguments filed 06/24/2026 have been fully considered but they are not persuasive. Applicant argues, page 12, Muroya does not teach separate bodies as the elements of Muroya (regions 90, 92) are not individually formed and then assembled together. The office respectfully disagrees regions (90), (92) are made of different materials, the former of copper, and the latter of aluminum based material [Abstract] These regions contain a boundary portion C between region (90) and region (92) in flange (80) [0043] fig. 6 and these regions are laminated together [0042] fig. 6. The process of lamination would inherently suggest there are multi layers which would constitute separate bodies as shown in fig. 6. Further individually formed and assembled is not claimed, and the Courts have held that making known elements separable is within the skill of a person of ordinary skill in the art. See In re Dulberg, 129 USPQ 348 (CCPA 1961) (see MPEP § 2144.04). Applicant argues, page 13, the examiner’s annotated fig. 6 of the thin portion and thick portion is incorrect, because Muroya has no through-hole, Muroya cannot have a thin portion “surrounding the through-hole.” The office respectfully disagrees as Muroya is not used to teach the through-hole, Yamada is relied upon to teach the flange portion includes a through hole through which the shaft portion is inserted, the shaft portion includes a swaged portion spreading along a surface of the flange portion opposite to the case and locating a peripheral edge portion of the through hole in the flange portion, as claimed, and in the combination of the through-hole of Yamada with the flange of Muroya would provide a thin portion surrounding the through hole and a thick portion surrounding the thin portion. Further in response to applicant's arguments against the references individually, one cannot show nonobviousness by attacking references individually where the rejections are based on combinations of references. See In re Keller, 642 F.2d 413, 208 USPQ 871 (CCPA 1981); In re Merck & Co., 800 F.2d 1091, 231 USPQ 375 (Fed. Cir. 1986). Applicant argues, page 13-14, Yamada’s plate 9 is a single metal and is not as the claimed second metal layer. The office respectfully disagrees as Yamada teaches plate 9 mainly made of copper, which is the same type of metal as the shaft portion of Muroya, has a surface on which a covering layer made of nickel or the like is formed [0069]. The office notes Yamada’s plate 9 is not relied upon to teach the claimed second metal. Further in response to applicant's arguments against the references individually, one cannot show nonobviousness by attacking references individually where the rejections are based on combinations of references. See In re Keller, 642 F.2d 413, 208 USPQ 871 (CCPA 1981); In re Merck & Co., 800 F.2d 1091, 231 USPQ 375 (Fed. Cir. 1986) D. Applicant argues, page 14, the combination of Muroya and Yamada does not teach the claimed features. The office respectfully disagrees Muroya is relied upon to teach the multilayer flange (80) consisting of first region (90) and second region (92), Yamada provides a swaging structure (8d), shaft (8b), with a through-hole (fig. 3) and in the combination Muroya’s flange (80) having protrusion (84) swaged, as taught by Yamada, and flange (80) provided a through-hole as taught by Yamada would provide the claimed structure as exemplified in fig. 7 of the instant specification as shown below. The figs. 5a and 7A of Yamada connection part (8c) with swaged part (8d) located on Muroya’s protrusion (84) of second metal (92) of flange (80) and provides the thick and thin parts as disclosed. Further in response to applicant's arguments against the references individually, one cannot show nonobviousness by attacking references individually where the rejections are based on combinations of references. See In re Keller, 642 F.2d 413, 208 USPQ 871 (CCPA 1981); In re Merck & Co., 800 F.2d 1091, 231 USPQ 375 (Fed. Cir. 1986) PNG media_image8.png 839 1614 media_image8.png Greyscale (The combination of Muroya, fig. 5a and Yamada, fig. 7A ) .The office respectfully disagrees as regions 90, 92 are laminated [0042], and both regions contain a boundary portion C between the regions 90, 92 [0043, 0055] fig. 6. Further individually formed and assembled is not claimed, and the Courts have held that making known elements separable is within the skill of a person of ordinary skill in the art. See In re Dulberg, 129 USPQ 348 (CCPA 1961) (see MPEP § 2144.04). In response to applicant's arguments, page 13-14, against the references individually, one cannot show nonobviousness by attacking references individually where the rejections are based on combinations of references. See In re Keller, 642 F.2d 413, 208 USPQ 871 (CCPA 1981); In re Merck & Co., 800 F.2d 1091, 231 USPQ 375 (Fed. Cir. 1986). Conclusion THIS ACTION IS MADE FINAL.
