Claim Rejections - 35 USC § 101 07-04-01 AIA 07-04 35 U.S.C. 101 reads as follows: Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title. Claims 1-20 are rejected under 35 U.S.C. 101 because the claimed invention is directed to an abstract idea without significantly more. Under step 1, claims 1-20 belong to a statutory category. Under Step 2A prong 1, the claims as a whole are identified as being directed to a judicial exception as claim 1 recite(s) “determining, by a processor, first and second charge/discharge test environments providing complementary characteristics for performance degradation of the higher-level battery device exhibits by performing a charge/discharge test with respect to the higher-level battery device;” and “deriving, by the processor, optimal operating conditions of the battery system in which the complementary characteristics under the first and second charge/discharge test environments are removed, upon determining that the test result of the charge/discharge test with respect to the lower-level battery device matches the complementary characteristics under the first and second charge/discharge test environments” which are directed to mathematical concepts and/or mental processes see for example, applicant’s specification Par. 33 and 59. Under Step 2A prong 2, evaluating whether the claim as a whole integrates the exception into a practical application of that exception, the judicial exception is not integrated into a practical application because “diagnosing a battery system having a hierarchical structure including a lower-level battery device and a higher-level battery device, the method comprising:” and “performing, by the processor, a charge/discharge test with respect to the lower-level battery device under the first and second charge/discharge test environments to determine whether a test result matches the complementary characteristics under the first and second charge/discharge test environments;” are considered to be generally linking the use of a judicial exception to a particular technological environment or field of use. The elements of “a processor” are considered to be generically recited computer elements do not add a meaningful limitation to the abstract idea because they amount to simply implementing the abstract idea on a computer. Under Step 2B, evaluating additional elements to determine whether they amount to an inventive concept both individually and in combination, the claim(s) does/do not include additional elements that are sufficient to amount to significantly more than the judicial exception because “diagnosing a battery system having a hierarchical structure including a lower-level battery device and a higher-level battery device, the method comprising:” and “performing, by the processor, a charge/discharge test with respect to the lower-level battery device under the first and second charge/discharge test environments to determine whether a test result matches the complementary characteristics under the first and second charge/discharge test environments;” are considered to be merely indicating a field of use or technological environment in which to apply a judicial exception do not amount to significantly more than the exception itself per MPEP 2106.05(h) and are well-understood, routine, and conventional activities/elements previously known to the industry per MPEP 2106.05(d) (see prior art of record). The elements of “a processor” are well-understood, routine, conventional computer functions as recognized by the court decisions listed in MPEP § 2106.05(d).

Under Step 2A prong 2, evaluating whether the claim as a whole integrates the exception into a practical application of that exception, the judicial exception is not integrated into a practical application because “An apparatus for diagnosing a battery system having a hierarchical structure including a lower-level battery device and a higher-level battery device, the apparatus comprising”, “wherein the processor is configured to perform a charge/discharge test with respect to the higher-level battery device”, and “perform a charge/discharge test with respect to the lower-level battery device under the first and second charge/discharge test environments” are considered to be generally linking the use of a judicial exception to a particular technological environment or field of use. The elements of “a processor” are considered to be generically recited computer elements do not add a meaningful limitation to the abstract idea because they amount to simply implementing the abstract idea on a computer. Under Step 2B, evaluating additional elements to determine whether they amount to an inventive concept both individually and in combination, the claim(s) does/do not include additional elements that are sufficient to amount to significantly more than the judicial exception because “An apparatus for diagnosing a battery system having a hierarchical structure including a lower-level battery device and a higher-level battery device, the apparatus comprising”, “wherein the processor is configured to perform a charge/discharge test with respect to the higher-level battery device”, and “perform a charge/discharge test with respect to the lower-level battery device under the first and second charge/discharge test environments” are considered to be merely indicating a field of use or technological environment in which to apply a judicial exception do not amount to significantly more than the exception itself per MPEP 2106.05(h) and are well-understood, routine, and conventional activities/elements previously known to the industry per MPEP 2106.05(d) (see prior art of record). The elements of “a processor” are well-understood, routine, conventional computer functions as recognized by the court decisions listed in MPEP § 2106.05(d). In claims 2, 7, the judicial exception is not integrated into a practical application or does/do not include additional elements that are sufficient to amount to significantly more than the judicial exception because they are considered to be data gathering steps required to use the correlation do not add a meaningful limitation to the method as they are insignificant extra-solution activity and re considered to be adding insignificant extra-solution activity to the judicial exception per MPEP 2106.05(g) and are well-understood, routine, conventional activities/elements previously known to the industry per MPEP 2106.05(d)(see prior art of record). In claim 6 and similarly 18 the elements of “changing, by the processor, the charge/discharge test conditions based on a charge/discharge test environment of each of the first and second battery units identified in the course of the charge/discharge test with respect to the lower-level battery device,”, “determine first and second battery units exhibiting complementary characteristics for performance degradation among the plurality of battery units;” and “analyzing, by the processor, a degree of degradation of the higher-level battery device after performing the charge/discharge test again” are considered to further describe the abstract ideas cited above. The judicial exception is not integrated into a practical application or does/do not include additional elements that are sufficient to amount to significantly more than the judicial exception because “wherein the lower-level battery device comprises a plurality of battery units,”, “when the test result of the charge/discharge test with respect to the lower-level battery device does not match the complementary characteristics under the first and second charge/discharge test environments: performing, by the processor, the charge/discharge test with respect to the lower-level battery device under charge/discharge test conditions defining electric current and temperature of each of the plurality of battery units to” and “followed by performing the charge/discharge test again with respect to the lower-level battery device under the changed charge/discharge test conditions;” are considered to be generally linking the use of a judicial exception to a particular technological environment or field of use and are considered to be merely indicating a field of use or technological environment in which to apply a judicial exception do not amount to significantly more than the exception itself per MPEP 2106.05(h) and are well-understood, routine, and conventional activities/elements previously known to the industry per MPEP 2106.05(d) (see prior art of record). In claims 3-5, 8-9, 11-14, 16 and 19-20 the limitations further describe the abstract ideas cited above and/or previously cited as not integrated into a practical application and not significantly more. In claims 10 and 15 the judicial exception is not integrated into a practical application or does/do not include additional elements that are sufficient to amount to significantly more than the judicial exception because they are considered to be generally linking the use of a judicial exception to a particular technological environment or field of use and are considered to be merely indicating a field of use or technological environment in which to apply a judicial exception do not amount to significantly more than the exception itself per MPEP 2106.05(h) and are well-understood, routine, and conventional activities/elements previously known to the industry per MPEP 2106.05(d) (see prior art of record).
