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 2-8 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.
Claim 2 recites the limitation the third chamber in line 3.  There is insufficient antecedent basis for this limitation in the claim.
Claim 3, line 4, recites “a second pump oil path” which is indefinite because it is unclear how there can be a second pump oil path without a previously claimed first pump oil path. Does the power transmission device have a first pump oil path?
The term “near” in claim 4, line 3, is a relative term which renders the claim indefinite. The term “near” is not defined by the claim, the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably apprised of the scope of the invention. What one person considers as near may not be the same as what another person considers as near thus the metes and bounds of the limitation cannot be determined.
Claim 6, line 7, recites “in other areas” which is indefinite because it is unclear if the other areas from claim 6 are the same other areas from claim 5, line 4. How are the two “other” areas different from each other or related to each other?
Allowable Subject Matter
Claims 1 and 9 are allowed over the prior art of record.
Claims 2-8 would be allowable if rewritten 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 and to include all of the limitations of the base claim and any intervening claims.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
Takahashi et al. (US 11,434,977 B2) discloses a vehicle drive device that is comprised of a housing that houses a power transmission mechanism, an electric oil pump and a mechanical oil pump move oil throughout the housing, the mechanical oil pump is located within the housing, and the electric oil pump is located outside the housing.

NEXT OFFICE ACTION: DETAILED ACTION
Notice of Pre-AIA  or AIA  Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Allowable Subject Matter
Claims 1-9 are allowed over the prior art of record.
The following is an examiner’s statement of reasons for allowance:
The prior art does not teach or render obvious the claimed combination of elements recited in claim 1, wherein a power transmission device is comprised of a case that houses a power transmission mechanism, a control valve that controls an oil pressure, the control valve is arranged upright inside the case, a first pump and a second pump that supply oil to the control valve, the case has a first support wall that supports an axis of rotation of the power transmission mechanism, a second support wall that supports the control valve and is aligned with the axis of rotation, a first chamber located on one side of the first support wall, a second chamber adjacent to the first chamber across the second support wall, a third support wall extending from the second support wall along the axis of rotation to the other side of the first support wall, the first pump is mounted on the first support wall inside the first chamber, and the second pump is mounted on the third support wall inside the second chamber. While the prior art discloses cases, control valves, pumps, support walls, oil, and chambers, the prior art does not teach or render obvious the power transmission device as claimed. One of ordinary skill in the art would not be motivated to connect the elements of each prior art reference to make the applicant's invention absent improper hindsight.
Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee.  Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.”
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
