Claim Rejections - 35 USC § 102
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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claim(s) 1 and 6 is/are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Hwangbo et al. (US 2022/0231345 A1, hereafter Hwangbo).
With regard to claim 1, Hwangbo teaches a secondary battery comprising:
a can (can 20) [0161, fig. 5];
an electrode assembly (electrode assembly 10) accommodated in the can and including a first uncoated portion (uncoated region 11) extending in a first direction (upward) and a second uncoated portion extending (uncoated region 12) in a second direction (downward) [0031, 0099, 0161-0166, 0182, 0194, fig. 5-7, fig. 13];
a first current collector plate (first current collector 60) electrically connected to the first uncoated portion of the electrode assembly [0031, 0099, 0161-0166, 0182, 0194, 0231 fig. 5-7, fig. 13];
a first terminal portion (terminal 40) coupled to the can and electrically connected to the first current collector plate [0031, 0099, 0161-0166, 0182, 0194, 0231 fig. 5-7, fig. 13]; and
a second terminal portion (cap 30 or can 20) coupled to the can and electrically connected to the second uncoated portion of the electrode assembly [0184, 0188, fig. 5-7, fig. 13].
With regard to claim 6, Hwangbo teaches a positive or negative electrode [0162].
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.
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.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claim(s) 1-13 is/are rejected under 35 U.S.C. 103 as being unpatentable over Makino et al (US 2024/0162474 A1, hereafter Makino) in view of Hwangbo et al. (US 2022/0231345 A1, hereafter Hwangbo).
With regard to claim 1, Makino teaches a secondary battery comprising:
a can (can 2) [0069, fig. 1];
an electrode assembly (jelly roll) accommodated in the can and including a first uncoated portion (exposed first conductive sheet) extending in a first direction (upward) [0069-0070, fig. 1];
a first current collector plate (electrode lead plate 6) electrically connected to the first uncoated portion of the electrode assembly [0071, fig. 6];
a first terminal portion (terminal 3) coupled to the can and electrically connected to the first current collector plate [0069, fig. 1].
Makino does not explicitly teach the details of the second terminal portion. However, in the same field of endeavor, Hwangbo teaches an electrode with two uncoated regions (uncoated regions 11 and 12) electrically connected to terminals (cap 30/can 20 and terminal 40) through current collectors [0031, 0099, 0161-0166, 0182, 0194, fig. 5-7, fig. 13]. It would have been obvious to one of ordinary skill in the art at the time the invention was made to use the second uncoated portion and second terminal portion of Hwangbo with the battery of Makino for the benefit of a second terminal portion that allows for increased space efficiency and energy density [Hwangbo 0126].

With regard to claim 2, Makino teaches the terminal portion includes a cap-up (raised area of terminal 3), the can further includes a can curling portion (curved edge of can 2) provided in an inward direction, and the first current collector plate further includes a current collector curling portion (protrusion 6a wrapping around terminal 3) provided in an inward direction between the can curling portion and the cap up [0069-0072, fig. 1].
With regard to claim 3, Makino teaches the curling portion (protrusion 6a wrapping around terminal 3) covers a bottom, side, and upper surface of the cap up (covers 3 sides of terminal 3 as seen in fig. 1) [0069-0072, fig. 1].
With regard to claim 4, Makino teaches the curling portion (protrusion 6a wrapping around terminal 3) is exposed to the outside of the can and the cap-up (as seen in fig. 1) [0069-0072, fig. 1].
With regard to claim 5, Makino teaches the cap-up (raised area of terminal 3) may include a vent notch [0004, 0022, 0077] but does not explicitly teach it is located on the bottom surface. However, this would be an obvious variant to one of ordinary skill in the art since it would perform the same function of rupturing to release pressure and only require a rearrangement of parts. See MPEP 2144.04 VI.
With regard to claim 6, Makino teaches positive and negative terminals [0002] therefore the first terminal would necessarily be positive or negative.
With regard to claim 7, Makino teaches the terminal portion includes a cap-up (raised area of terminal 3), the cap up further includes a cap up seaming portion provided in an outward direction (inner surfaces in contact with protrusion 6a), the can further includes a can seaming portion (end side 2a) provided in an outward direction of an end portion (upper end of can 2), and the first current collector plate further includes a current collector plate seaming portion (protrusion 6a wrapping around terminal 3) provided in an outward direction between the cap up seaming portion and the can seaming portion [0069-0072, fig. 1].
With regard to claim 8, Makino teaches the current collector plate seaming portion (protrusion 6a wrapping around terminal 3) covers an inner (lower), side (inner sidewall), and outer (upper) surface of the can seaming portion (end side 2a) [0069-0072, fig. 1].
With regard to claim 9, Makino teaches the cap up seaming portion (inner surfaces of terminal 3 in contact with protrusion 6a) covers an inner (lower interior wall), side (sidewall), and outer (upper interior wall) of the current collector plate seaming portion (protrusion 6a wrapping around terminal 3) [0069-0072, fig. 1].
With regard to claim 10, Makino teaches the cap-up (raised area of terminal 3) may include a vent notch [0004, 0022, 0077] but does not explicitly teach it is located on the bottom surface. However, this would be an obvious variant to one of ordinary skill in the art since it would perform the same function of rupturing to release pressure and only require a rearrangement of parts. See MPEP 2144.04 VI.
With regard to claims 11-12, Makino does not explicitly teach the details of the second terminal portion. However, in the same field of endeavor, Hwangbo teaches an electrode with an uncoated region (uncoated regions 11) electrically connected to a terminal (terminal 40) including a pillar portion (terminal insert portion 42) extending from a current collector (60) with an area corresponding to the uncoated region (as seen in fig. 7) and penetrating the can, and a terminal surface (terminal exposing portion 41) extending from the pillar portion and located outside the can [0031, 0099, 0161-0166, 0182, 0194-0195, fig. 5-7, fig. 13]. Hwangbo further teaches an insulating portion (gasket 50) between the terminal portion and can (claim 12) [0161, fig. 7]. It would have been obvious to one of ordinary skill in the art at the time the invention was made to use the second uncoated portion and second terminal portion of Hwangbo with the battery of Makino for the benefit of a second terminal portion that allows for increased space efficiency and energy density [Hwangbo 0126].
With regard to claim 13, Makino teaches positive and negative terminals [0002] therefore the second terminal would necessarily be positive or negative.
