Priority
Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55.
Information Disclosure Statement
The information disclosure statement filed 04/27/2023, 07/05/2024, 07/05/2024, 10/15/2024, 10/15/2024, 10/21/2024, 10/21/2024, 08/22/2025 and 08/22/2025 fails to comply with 37 CFR 1.98(a)(3)(i) because it does not include a concise explanation of the relevance, as it is presently understood by the individual designated in 37 CFR 1.56(c) most knowledgeable about the content of the information, of each reference listed that is not in the English language. It has been placed in the application file, but the information referred to therein has not been considered.

Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claims 26-29 and 37 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Regarding claim 26, the limitation “an electric machine from a machine unit” renders the claim indefinite because it is unclear which machine(s) recited in claims 18-19 the limitation is referring to.
Regarding claims 27 and 37, the claims fail to provide adequate antecedence basis for the limitation “the switchable couplings”.
Regarding claims 28-29, the claims are indefinite because they are directly or indirectly depend on claim 27.
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)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
(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 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.
Claim(s) 21, 24, 26 and 29 is/are rejected under 35 U.S.C. 103 as being unpatentable over Tarasinski et al. (US 2011/0042155 A1) in view of Murata et al. (US 2017/0264229 A1).
Regarding claims 24 and 26, Tarasinski fails to disclose, but Murata teaches at least one of the second or fourth switching devices in the second operating state is adapted to short-circuit terminals of the respective electric machine, thereby causing an active short-circuit of the electric machine (e.g. Abstract & [0074]: short-circuit the motor when inverter has a failure).
Since Tarasinski discloses the switching devices could be converter, e.g. inverter, for providing power to the machines, i.e. motor, it would have been obvious to one skilled in the art before the effective filing date of the claimed invention to modify the teachings of Tarasinski with the teachings of Murata to short-circuit the machine when converter has a failure so as to protect the system from being damaged.
Regarding claim 21, Murata teaches at least one of the first or third switching devices has at least one freewheel (e.g. Fig. 2: freewheel diode in switching devices of inverter).
Regarding claim 29, Murata teaches the state of at least one of the drive system or the coupled machine is detected by sensors (e.g. [0039]).
Claim(s) 30 and 32 is/are rejected under 35 U.S.C. 103 as being unpatentable over Tarasinski et al. (US 2011/0042155 A1).
Regarding claims 30 and 32, Tarasinski discloses the general aspect of the claimed invention except a drive power of the coupled machine of at least 0.5MW.
According to paragraph [0106] of the specification of the instant application, the claimed 0.5MW is particularly advantageous in heavy duty vehicle operation, such as “PTI-PTO (PowerTakeIn-PowerTakeOff) application”.
Although Tarasinski does not disclose the power is 0.5MW, Tarasinski discloses its invention is for power take-off drive (PTO) (e.g. [0005]).
Since applicant does not provide any reasons for choosing 0.5MW as the drive power, other than it is suitable for power take-off drive, the examiner is taking Official notice that it is known in the art to utilize any suitable power in the field of PTO as drive power since discovering optimum value of a result effective variable involves only routine skill in the art. In re Boesch, 617 F. 2d 272, 205 USPQ 215 (CCPA 1980).
