Relevant MPEP Sections
MPEP 2113 relating to Product by Process limitations - “[E]ven though product-by-process claims are limited by and defined by the process, determination of patentability is based on the product itself. The patentability of a product does not depend on its method of production. If the product in the product-by-process claim is the same as or obvious from a product of the prior art, the claim is unpatentable even though the prior product was made by a different process.” In re Thorpe, 777 F.2d 695, 698, 227 USPQ 964, 966 (Fed. Cir. 1985)
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.
Claims 1-23 are rejected under 35 U.S.C. 103 as being unpatentable over Yoo et al. (KR 10-2015-0089716 cited in IDS, a machine translation of which is attached).
In regard to claim 1, Yoo et al. teach a battery comprising: a battery cell (electrode assemblies 120) having electrode leads (uncoated portions 124) protruding in at least one direction; and at least one bus bar (current collecting plate 131, 231) disposed at one side of the plurality of battery cells (figure 1), each of the at least one bus bar including: a bus bar body (see annotated figure 7 below – current collecting plate 230) having a top planar surface parallel to the planar surface of the battery cell 120; a pair of first surfaces connected to opposite sides of the top planar surface, respectively, and extending away from the top planar surface, the pair of first surfaces (connection portion 231d) having a first slope Ѳ1 relative to the top planar surface, wherein the pair of first surfaces are inclined; and a pair of second surfaces (connection portions 231e and 231f) directly connected to the pair of first surfaces, respectively, and extending away from the pair of first surfaces, the pair of second surfaces having a second slope Ѳ3 relative to the top planar surface that is different from the first slope, wherein the second slope is not perpendicular to the top planar surface, and wherein the electrode leads are welded to at least one of the pair of second surfaces (see pages 3-6 of attached machine translation –angle Ѳ has been reproduced as “angle?” in the translation).

While the prior art only teaches a single battery cell in the example, it would have been obvious to one of ordinary skill in the art at the before the effective filing date of the claimed invention filed to include multiple cells stacked together on their planar surfaces as duplication of the prior art to arrive at desired current and voltage outputs are an obvious modification (see MPEP 2144.05 Part VI).
Further, the prior art describes selecting a geometry of the to prevent the laser from being applied inside the current collecting plate 230 (page 7) and shows many different possible embodiments, therefore depending on the conditions for welding (i.e. direction, power etc.), changes to size and shape of the prior art busbar are an obvious modification absent evidence to the contrary (see MPEP 2144.04 Part IV).
In regard to claim 2, the entire top and side surfaces of each of the at least one bus bar are composed of five (5) sides (figure 7).
In regard to claim 3, the pair of second surfaces are connected to a bottom surface of the bus bar body (figure 7, page 6).

Double Patenting
The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969).
A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b).
The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13.
The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission.
