Claim 11 is rejected under 35 U.S.C. 103 as being unpatentable over Elfering et al. (US 20180366697 A1) in view of He (CN 107768575 A) and Pare et al. (US 20190393461 A) as applied to claim 1, and further in view of Hamazaki (JP 2000260401 A). The English translation of JP 2000260401 A is used as reference as attached.
Regarding to claim 11: Elfering et al. in view of He and Pare et al. discloses a battery pack as described above in paragraph 3. Elfering et al. fail to explicitly disclose at least one of the at least three resilient members is associated with a Shore durometer value, or Shore hardness, between 60-100 measured with durometer type A according to DIN ISO 7619-1. However, He discloses a battery housing structure (pg. 1). The battery housing structure comprises tension elastic elements (430) and limiting and fixing plates (310, 320, 330, 340) (par. 31, fig. 1). The tension elastic elements (430) are springs and the limiting and fixing plates (310, 320, 330, 340) are elastic soft rubber plate (par. 32). He further discloses both the elastic soft rubber and the tension elastic elements can limit the range of movement of the battery and both have buffering effect to protects the battery from damage (par. 34). It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to substitute springs with elastic rubbers because it is merely the selection of functionally equivalent elastic parts to buffer collision impact as shown by He. The simple substitution of one known element for another is likely to be obvious when predictable results are achieved. See KSR International Co. v. Teleflex Inc., 550 U.S. 398, 415-421, USPQ2d 1385, 1395 – 97 (2007) (see MPEP § 2143, B.).
Furthermore, Hamazaki discloses a battery pack (par. 1) The power pack comprises silicone rubber (3) around batteries (1) (par. 17, fig. 1). Hamazaki further recognizes if Shore hardness of the silicon rubber is 70 or more, the shape of the silicone rubber can be stabilized. If the Shore hardness is set to 95 or less, the elasticity of the silicone rubber will improve vibration resistance and impact resistance (par. 14). Therefore, one of ordinary skill in the art before the effective filing date of the claimed invention can adjust the Shore hardness of the silicon rubber to yield more or less elasticity of the silicone rubber for vibration and impact protection. Discovery of optimum value of result effective variable in known process is ordinarily within skill of art. In re Boesch, CCPA 1980, 617 F.2d 272, 205 USPQ215.
Claim 12 is rejected under 35 U.S.C. 103 as being unpatentable over Elfering et al. (US 20180366697 A1) in view of He (CN 107768575 A) and Pare et al. (US 20190393461 A) as applied to claim 1, and further in view of Ro Kamp et al. (US 20100221594 A1).

Elfering et al., He, and Pare et al. fail to explicitly disclose the battery having a weight between 2500g and 5500g. However, Ro Kamp et al. disclose a hand-held electric device has a device housing with a battery pack compartment (abstract). Ro Kamp et al. further recognize when it is necessary to provide greater voltage and greater power, the battery packs requires more battery cells which can increase the weight of the battery pack (par. 3, 30). Therefore, one of ordinary skill in the art before the effective filing date of the claimed invention can adjust the weight of the battery cells (10) of Elfering et al. to yield a desired voltage for a power tool. Discovery of optimum value of result effective variable in known process is ordinarily within skill of art. In re Boesch, CCPA 1980, 617 F.2d 272, 205 USPQ215.
Claim 14 is rejected under 35 U.S.C. 103 as being unpatentable over Elfering et al. (US 20180366697 A1) in view of He (CN 107768575 A) and Pare et al. (US 20190393461 A) as applied to claim 1, and further in view of Martinsson et al. (US 20110308831).
Regarding to claim 14: Elfering et al. in view of He and Pare et al. discloses a battery pack as described above in paragraph 3. Elfering et al., He, and Pare et al fail to explicitly disclose the battery adapted to be inserted into a through-hole battery compartment in a power tool. However, Martinsson et al. disclose a battery pack for powering a battery powered tool (abstract). The battery pack (320) is placed in a through aperture (310) (equivalent to a through-hole battery compartment) to power the corresponding power tool (par. 39, fig. 3A, 3B). It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to use the through aperture (310) of Martinsson et al. to place the battery pack (100) of Elfering et al. because Martinsson et al. teach that the operating life of the powered tools and their batteries can increased and the overall performance can be improved (par. 5).
Claim 15 is rejected under 35 U.S.C. 103 as being unpatentable over Elfering et al. (US 20180366697 A1) in view of He (CN 107768575 A) and Chellew (US 20140154532).
Regarding to claim 15: Elfering et al. discloses a battery pack and a method of assembling a battery pack (abstract). The battery pack (100) comprising:
a main housing (108) including a bottom portion (112) and a top portion (116) (equivalent to a second gable) (par. 135, fig. 16), wherein the bottom portion (112) comprises side walls (128) (equivalent to a central housing) and a floor (120) (equivalent to a first gable) (par. 135, 136, fig. 17, 20I) (see fig. above), the floor (112) being arranged opposite to the top portion (116) (fig. 20I) and facing in an insertion direction of the battery (fig. 46A) (see fig. above), wherein the floor (120) and the top portion (116) mate with the side walls (128) along respective gable rims (see fig. above), thereby defining a volume delimited by the floor (120) and the top portion (116) and the side walls (128) (fig. 46A), wherein each of the top portion (116) and the floor (120) defines a respective top portion and floor volume.
Elfering et al. fail to explicitly disclose a battery cell pack arranged suspended in the volume by at least three resilient members, wherein the at least three resilient members extend in a direction diagonally away from a mass center of the battery cell pack towards a supporting location on one of the respective gable portion rims. However, He discloses a battery housing structure (pg. 1). The battery housing structure comprises a battery housing (100), a battery module (200) (equivalent to a battery cell pack), tension elastic members (430) (par. 31, fig. 1). The battery module (200) is suspended by tension elastic members (430) (equivalent to at least three resilient members) (par. 30, 31, fig. 1). Each tension elastic member (430) extends in a direction diagonally away from a mass center of the battery module (200) (fig. 1) towards a fixing block (410, 420) (equivalent to a supporting location) on a peripheral edge (equivalent to a rim) (par. 30, 31, fig. 1). It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to use the battery house structure (suspending the battery cell pack diagonally) of He to suspend the battery cell pack of Elfering et al. because He teaches the battery housing structure can buffer the battery module and protect the battery from damage (par. 7).
Elfering et al. and He fail to explicitly disclose the central housing is the same for each battery type in the plurality of battery types, and the first and/or second gable volume differs between a first battery type and a second battery type in the plurality of battery types. However, Chellew discloses battery cell carriers (abstract). The cell carrier (10) can accommodate different battery types (par. 53, 58, fig. 1, 2). Different volumes of lower bodies (17b) (equivalent to different first gable volumes) of battery packs (17) are used to accommodate the different battery types (par. 78, 82, fig. 9B, 9C,12, 13). It would be obvious to the skilled artisan to use the different volumes of the lower bodies (17b) of Chellew as the volumes of the floor (120) of Elfering et al. because Chellew teaches different volumes can accommodate different rows of batter cells for different configuration applications (par. 69).
