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 1-11 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.
The claims are generally indefinite, failing to conform with current U.S. practice. They appear to be a literal translation into English from a foreign document and are replete with grammatical and idiomatic errors. Below is a small sampling of the 112 issues and is not intended as a comprehensive list of necessary edits. Complete revision of the claims is necessary.

Allowable Subject Matter
Claims 1-11 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action.
Claims 12-16 allowed.
The following is a statement of reasons for the indication of allowable subject matter:
The claims are patentable over the prior art of record because the teachings of the references taken as a whole do not show or render obvious the combination set forth in claims 1 and 12, including every structural element recited in the claims, especially the configuration of the 3/2 directional control valve adjustable between a first position and a second position via a control line and a control pressure, wherein, in the first position of the 3/2 directional control valve, a fluid line connects the motor- pump unit to the heat exchanger, an outlet of the heat exchanger branches into the second and third partial volume flows, the third partial volume flow runs directly to the stator, and the second partial volume flow is fed to the rotor via a hydraulically controllable non-return valve, and wherein a first fluid path bypasses the heat exchanger to provide the first partial volume flow to the gearbox.
More specifically, regarding claims 1 and 12, Schweiger et al., DE 102022214389 is considered the closest prior art of record.

Schweiger et al. discloses an arrangement for needs-based control of flow temperatures of cooling and lubricating oil in an electric traction drive (see abstract), the arrangement comprising: an electrically controllable motor-pump unit (2) configured to operate in a first direction of rotation (A) and an opposite second direction of rotation (B), and to provide a selectable first pressure level and a higher second pressure level by closed-loop control of rotational speed (“the distribution of the partial volume flows can be additionally influenced via the control pressure and thus via the pump speed of pump 4”); a hydraulic unit (see fig 5) coupled to the motor-pump unit (2); a heat exchanger (5) fluidly coupled to the hydraulic unit (as described above); multiple fluid outlets (connected to 11,12,13) configured to provide a first partial volume flow (10”’) to a gearbox (13), a second partial volume flow (10’) to a rotor (11) of an electric drive unit (11,12), and a third partial volume flow (10”) to a stator of the electric drive unit (12), each for at least one of cooling, heating, and lubrication, wherein the hydraulic unit (as described above) includes: a shuttle valve (7) downstream of the motor-pump unit (2); and a hydraulically controllable valve (25). Schweiger et al. does not specify that the valve comprises a 3/2 directional control valve adjustable between a first position and a second position via a control line and a control pressure, wherein, in the first position of the 3/2 directional control valve, a fluid line connects the motor- pump unit to the heat exchanger, an outlet of the heat exchanger branches into the second and third partial volume flows, the third partial volume flow runs directly to the stator, and the second partial volume flow is fed to the rotor via a hydraulically controllable non-return valve, and wherein a first fluid path bypasses the heat exchanger to provide the first partial volume flow to the gearbox. Incorporating this feature into the system of Schweiger et al. is consider non-obvious.
None of the references of the prior art teach or suggest the elements of the lubrication system as advanced above and such do not provide the necessary motivation, absent applicant's specification, for modifying the system in the manner required by the claims.
