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.
Claims 12-13 are rejected under 35 U.S.C. 103 as being unpatentable over Torosyan 20190326623.
Regarding claim 12, Torosyan further teaches wherein each spring element (each pair of 308s in Fig. 3A, or each pair of 408s in Fig. 4A) is configured to provide, when compressed, a linear force (the spring force/force exert by each pair of 308, see [0029 and 0031], or each pair of 408, see [0032 and 0034]) towards the respective connection tab (106 or 108 in Fig. 1B) to be welded.
Torosyan does not teach said liner force is up to 4N.
However, Torosyan further the linear force (the spring force/force exert by each pair of 308 that determined by the selected material, see [0029 and 0031], or each pair of 408 that determined by the selected material, see [0032 and 0034]) provided toward the respective connection tab (106 or 108 in Fig. 1B) causes a position of the corresponding clamping element (the 302 in Fig. 3A or the 402 in Fig. 4A) to move along a direction (along the center axis, see demonstration in annotated Fig. 3B in claim 3) substantially perpendicular to the clamping face (the bottom surface of 202, e.g., where recess 212 is in Fig. 5A or where recess 512 is in Fig. 5B) until a zero-gap (see [0029 or 0032]) is formed between the respective tab (106 or 108 in Fig. 1B) and the corresponding terminal (the positive terminal or the negative terminal per [0023]) in order to improve battery module performance ([0003]).
A particular parameter is a result-effective variable when the variable is known to achieve a recognized result. See In re Antonie, 559 F.2d 618, 620, 195 USPQ 6,8 (CCPA 1977). Therefore, an ordinary skilled worker would recognize that a moving distance of the position of the corresponding clamping element determined by the linear force provided by the spring element is a results-effective variable that controls the battery module performance. Thus, the claimed limitation of the liner force is up to 4N is found to be an obvious optimization of the prior art obtainable by an ordinary skilled worker through routine experimentation. Further, it appears that one of ordinary skill in the art would have had a reasonable expectation of success in modifying the spring element of Torosyan to provide a linear force of up to 4N as it involves only adjusting a material of the spring element of Torosyan disclosed to require adjustment.
"[W]here the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation", In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955). The presence of a known result-effective variable would be a motivation for a person of ordinary skill in the art to experiment to reach another workable product or process. See KSR; MPEP 2144.05(II)(B).
Therefore, it would have been obvious to one of ordinary skill in the art at the time of effective filing to modify Torosyan to provide a linear force of up to 4N.
Regarding claim 13, Torosyan further teaches wherein each spring element (each pair of 308s in Fig. 3A, or each pair of 408s in Fig. 4A) is configured to allow a position of the corresponding clamping element (the 302 in Fig. 3A or the 402 in Fig. 4A) with respect to the clamping face (the bottom surface of 202, e.g., where recess 212 is in Fig. 5A or where recess 512 is in Fig. 5B), when compressed, to move along a direction (along the center axis, see demonstration in annotated Fig. 3B in claim 3) substantially perpendicular to the clamping face (the bottom surface of 202, e.g., where recess 212 is in Fig. 5A or where recess 512 is in Fig. 5B).
Torosyan does not teach moving by up to 2.2 mm.
However, Torosyan further a linear force (the spring force/force exert by each pair of 308 that determined by the selected material, see [0029 and 0031], or each pair of 408 that determined by the selected material, see [0032 and 0034]) provided toward the respective connection tab (106 or 108 in Fig. 1B) causes a position of the corresponding clamping element (the 302 in Fig. 3A or the 402 in Fig. 4A) to move along a direction (along the center axis, see demonstration in annotated Fig. 3B in claim 3) substantially perpendicular to the clamping face (the bottom surface of 202, e.g., where recess 212 is in Fig. 5A or where recess 512 is in Fig. 5B) until a zero-gap (see [0029 or 0032]) is formed between the respective tab (106 or 108 in Fig. 1B) and the corresponding terminal (the positive terminal or the negative terminal per [0023]) in order to improve battery module performance ([0003]).
A particular parameter is a result-effective variable when the variable is known to achieve a recognized result. See In re Antonie, 559 F.2d 618, 620, 195 USPQ 6,8 (CCPA 1977). Therefore, an ordinary skilled worker would recognize that a moving distance of the position of the corresponding clamping element determined by the linear force provided by the spring element is a results-effective variable that controls the battery module performance. Thus, the claimed limitation of allow a position of the corresponding clamping element by up to 2.2 mm is found to be an obvious optimization of the prior art obtainable by an ordinary skilled worker through routine experimentation. Further, it appears that one of ordinary skill in the art would have had a reasonable expectation of success in modifying the spring element of Torosyan to provide a linear force to allow the corresponding clamping element to move up to 2.2 mm as it involves only adjusting a material of the spring element of Torosyan disclosed to require adjustment.
"[W]here the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation", In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955). The presence of a known result-effective variable would be a motivation for a person of ordinary skill in the art to experiment to reach another workable product or process. See KSR; MPEP 2144.05(II)(B).
Therefore, it would have been obvious to one of ordinary skill in the art at the time of effective filing to modify Torosyan to provide a linear force to allow a position of the corresponding clamping element with respect to the clamping face, when compressed, to move along a direction substantially perpendicular to the clamping face by up to 2.2mm.
Claims 16-17 are rejected under 35 U.S.C. 103 as being unpatentable over Torosyan 20190326623 in view of REINGRUBER 20230035654.
Regarding claim 16, Torosyan further teaches wherein each clamping element (each 302 in Fig. 3A) has an internal dimension (a diameter of the contact end 310, annotated Fig. 3B) across the contact end (310) through a central point (on the center axis of 302, annotated Fig. 3B) of contact end face (interpreted as contact end, which is 310), wherein the contact end (310) is pressing on the corresponding terminal end (positive end [0023]) of the electrical cell having a diameter of between 18.6 mm and 21 mm ([0024]).

Torosyan does not teach said internal dimension is between 5 mm and 9 mm.
However, REINGRUBER teaches each clamping element (7, which is a hollow rod-shaped/pin-shaped holder in Fig. 3 and [0062-0064]) has an internal dimension (a diameter of a contact end of 7 where 7 presses on connection tab 2, see Fig. 3 and [0062]) across the contact end (a contact end of 7 where 7 presses on connection tab 2, see annotated Fig. 3 and [0062]) through a central point (on the center axis in annotated Fig. 3) of contact end face (where 7 contact 2), wherein the internal dimension is determined by a diameter of the electrical cell (per [0062-0064], the diameter of the contact end face of 7 is between 5% to 30% of a diameter of the corresponding cell) and the laser beam landing location/area (the diameter of the contact end may be lager to prevent blocking laser beam, [0055-0056]) in order to achieve a better spot welding ([0054-0055]).

A particular parameter is a result-effective variable when the variable is known to achieve a recognized result. See In re Antonie, 559 F.2d 618, 620, 195 USPQ 6,8 (CCPA 1977). Therefore, an ordinary skilled worker would recognize that the internal dimension of the contact end, which determined by a diameter of the electrical cell and the laser beam location/area, is a results-effective variable that controls the quality of spot welding. Thus, the claimed limitation of an internal dimension across the contact end through a central point of contact end face of between 5 mm and 9 mm is found to be an obvious optimization of the prior art obtainable by an ordinary skilled worker through routine experimentation. Further, it appears that one of ordinary skill in the art would have had a reasonable expectation of success in modifying the clamping element of Torosyan to have an internal dimension across the contact end through a central point of contact end face of between 5 mm and 9 mm, as it involves only adjusting the size of clamping element of Torosyan disclosed to require adjustment.
"[W]here the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation", In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955). The presence of a known result-effective variable would be a motivation for a person of ordinary skill in the art to experiment to reach another workable product or process. See KSR; MPEP 2144.05(II)(B).
Therefore, it would have been obvious to one of ordinary skill in the art at the time of effective filing to modify Torosyan with REINGRUBER to have an internal dimension across the mounting end through a central point of the mounting end of between 5 mm and 9 mm in order to achieve a better spot welding.
Regarding claim 17, Torosyan further teaches a distance (annotated Fig. 3B) between the mounting end (a distal end of 306, annotated Fig. 3B) and the contact end (310) is defined by an angle (beta 1, Fig. 3B) and a diameter (annotated Fig. 3B) of the contact end (310; per [0029-0030], 302 and 306 connect to 302 form the angle beta 1 having a value that allows the laser beam to pass through, i.e., when beta 1 is defined, larger distance will cause a smaller diameter, see annotated Fig. 3B), wherein the contact end (310) is pressing on the corresponding terminal end (positive end [0023]) of the electrical cell having a diameter of between 18.6 mm and 21 mm ([0024]).

Torosyan does not teach said distance is between 14 mm and 21mm.
However, REINGRUBER teaches each clamping element (7, which is a hollow rod-shaped/pin-shaped holder in Fig. 3 and [0062-0064]) has a diameter of a contact end (where 7 presses on connection tab 2, see annotated Fig. 3 and [0062]), wherein the diameter is determined by a diameter of the electrical cell (per [0062-0064], the diameter of the contact end face of 7 is between 5% to 30% of a diameter of the corresponding cell) and the laser beam landing location/area (the diameter of the contact end may be lager to prevent blocking laser beam, [0055-0056]) in order to achieve a better spot welding ([0054-0055]).

Claim 19 is rejected under 35 U.S.C. 103 as being unpatentable over Torosyan 20190326623 in view of NORTH 20220181752.
Regarding claim 19, Torosyan does not teach the support part comprising between 20 and 100 clamping elements.
However, NORTH teaches a cell array (a battery pack) comprising a plurality
of electrical cells (430), wherein a number of the plurality of electrical cells is
determined by a total required voltage of the cell array ([0031]).
A particular parameter is a result-effective variable when the variable is
known to achieve a recognized result. See In re Antonie, 559 F.2d 618, 620, 195
USPQ 6,8 (CCPA 1977). Therefore, an ordinary skilled worker would recognize that
a number of the plurality of electrical cells, which corresponding to a number of the plurality of clamping elements, is a results-effective variable that controls a total required voltage of the cell array. Thus, the claimed limitation of the clamping apparatus comprises between 20 and 100 clamping elements is found to be an obvious optimization of the prior art obtainable by an ordinary skilled worker through routine experimentation. Further, it appears that one of ordinary skill in the art would have had a reasonable expectation of success in modifying the plurality of clamping elements of Torosyan to have the clamping apparatus
comprising between 20 and 100 clamping elements, as it involves only adjusting a
number of the plurality of electrical cells of Torosyan disclosed to require
adjustment.
"[W]here the general conditions of a claim are disclosed in the prior art, it is

The presence of a known result-effective variable would be a motivation for a person of ordinary skill in the art to experiment to reach another workable product or process. See KSR; MPEP 2144.05(II)(B).
Therefore, it would have been obvious to one of ordinary skill in the art at
the time of effective filing to modify Torosyan with NORTH’s adjusting the
number of the plurality of electrical cells according to the required total voltage of
the cell array, such that wherein the clamping apparatus comprises between 20
and 100 clamping elements.
Claims 3, 8-9, and 11 are rejected under 35 U.S.C. 103 as being unpatentable over UNANNOUNCED INVENTOR CN111037093A in view of MIAO WO2020136928A1.
Regarding claim 3, UNANNOUNCED INVENTOR further teaches wherein each spring element (each pair of 146s, see Fig. 5) comprises at least one spring portion (an end of 146, annotated Fig. 5) extending inwardly towards (note: “toward” does not mean “into”) the central space (1442, relative to the center axis in annotated Fig. 5) of the corresponding clamping element (the corresponding 144, see Fig. 5), and wherein each clamping element (each 144, see Fig. 5) is mounted on the at least one spring finger portion (the end of 146, annotated Fig. 5) of the corresponding spring element (the respective pair of 146s, Fig. 5).

UNANNOUNCED INVENTOR does not teach said at least one spring portion is at least one spring finger portion.
However, MIAO teaches a spring element (wave spring 3611, Fig. 10 and p. 10, ll. 16-33) comprising at least one spring finger portion (annotated Fig. 10).

It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to modify the disclosed but non-depicted spring element of UNANNOUNCED INVENTOR with MIAO’s spring element comprises at least one spring finger portion because it is noted that the use of a known prior art structure, in this case the use of wave spring as a spring element taught by MIAO, to obtain predictable results, in this case providing a compressive force, was an obvious extension of prior art teachings, KSR; MPEP 2141 III A.
Regarding claim 8, UNANNOUNCED INVENTOR in view of MIAO further teaches wherein: the support part (UNANNOUNCED INVENTOR’s 12 and 142 in UNANNOUNCED INVENTOR’s Fig. 1) comprises a clamping plate (UNANNOUNCED INVENTOR’s 142) comprising the clamping face (UNANNOUNCED INVENTOR’s 1425 in UNANNOUNCED INVENTOR’s Fig. 5), and a back plate (UNANNOUNCED INVENTOR’s 12) parallel with the clamping plate (UNANNOUNCED INVENTOR’s 142, see UNANNOUNCED INVENTOR’s Fig. 1); and each spring element (UNANNOUNCED INVENTOR’s each pair of 146s in UNANNOUNCED INVENTOR’s Fig. 5, which is MIAO’s wave spring 3611 in MIAO’s Fig. 10) comprises a spring plate (a plate-shaped layer of MIAO’s wave spring 3611, see MIAO’s annotated Fig. 10) sandwiched between the clamping plate (UNANNOUNCED INVENTOR’s 12) and the back plate (UNANNOUNCED INVENTOR’s 142) to hold each spring element (UNANNOUNCED INVENTOR’s each pair of 146s in UNANNOUNCED INVENTOR’s Fig. 5, which is MIAO’s wave spring 3611 in MIAO’s Fig. 10) in the support part (UNANNOUNCED INVENTOR’s 12 and 142, see UNANNOUNCED INVENTOR’s Figs. 1 and 5 and 7), and wherein each spring element (a portion of UNANNOUNCED INVENTOR’s each pair of 146s, which is the portion of MIAO’s wave spring 3611 marked in MIAO’s annotated Fig. 10) extends from the spring plate (a plate-shaped layer of MIAO’s wave spring 3611, see MIAO’s annotated Fig. 10).

Regarding claim 9, UNANNOUNCED INVENTOR in view of MIAO further teaches a plurality of individual spring plates (UNANNOUNCED INVENTOR’s plurality of individual spring elements 146s, see UNANNOUNCED INVENTOR’s Figs. 5 and 7, and each said individual spring element is Miao’s wave spring 3611 in Miao’s Fig. 10, which is a multi-layer-plate-shaped spring, see MIAO’s Fig. 10) each corresponding to a respective clamping element (UNANNOUNCED INVENTOR’s corresponding 144, see UNANNOUNCED INVENTOR’s Figs. 5 and 7) of the plurality of clamping elements (UNANNOUNCED INVENTOR’s 144s).
Regarding claim 11, UNANNOUNCED INVENTOR in view of MIAO further teaches the at least one spring finger portion (MIAO’s annotated Fig. 10) comprises an elongated connection tab portion (MIAO’s annotated Fig. 10) and an end connection tab portion (MIAO’s annotated Fig. 10); the at least one spring finger portion (MIAO’s annotated Fig. 10) is bent (in order to form the last layer of MIAO’s wave spring 3611, see MIAO’s annotated Fig. 10) so that the elongated connection tab portion (MIAO’s annotated Fig. 10) and the clamping face (UNANNOUNCED INVENTOR’s 1425) are in substantially parallel planes (when MIAO’s wave spring 3611 is placed in UNANNOUNCED INVENTOR’s 1422 as UNANNOUNCED INVENTOR’s spring element 146 as shown in UNANNOUNCED INVENTOR’s Fig. 5, MIAO’s at least one spring finger portion abuts to UNANNOUNCED INVENTOR’s wall 1421, and thus is substantially parallel to UNANNOUNCED INVENTOR’s clamping face 1425); and the clamping element (UNANNOUNCED INVENTOR’s 144) is mounted on the end connection tab portion (because UNANNOUNCED INVENTOR’s 144 abuts to UNANNOUNCED INVENTOR’s spring element 146 as shown in UNANNOUNCED INVENTOR’s Fig. 5, which is MIAO’s wave spring 3611).
