Office Action

§102
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 . Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Claim Objections Claim 20 is objected to because of the following informalities: Claim 20, line 9 recites “the first output shaft (5), the first output shaft (5)…” which appears to be a typographical error. An appropriate correction would be deleting one of the repeated statements. Claim 20, line 11 recites “the second output shaft (6), the second output shaft (6)…” which appears to be a typographical error. An appropriate correction would be deleting one of the repeated statements. Appropriate correction is required. Claim Rejections - 35 USC § 102 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(s) 12-13 is/are rejected under 35 U.S.C. 102(a)(1)/(a)(2) as being anticipated by Yamaguchi et al. (USPN 4,766,773). Yamaguchi discloses an oil guiding arrangement for a transmission (T) comprising: a first output shaft (9), a second output shaft (5 – considered output shaft as it receives torque and outputs it to the transmission), and a bearing (8) of the first output shaft, the first output shaft being rotatably supported at the second output shaft by the bearing, the second output shaft comprising an offset section (see Fig. 2 where bearing 6 supports shaft 5 up to 5c) extending in a radial direction, the offset section defining an oil channel (5b) extending in an axial direction (5b extends at least partially in the axially direction of the shaft) for supplying oil to the bearing of the first output shaft, the oil guiding arrangement comprising: a stationary component (4), the stationary component defining a main oil channel (4e) and an opening (end of 4e near “a”), the opening opening from the oil channel into an oil volume (“a”), the second output shaft being rotatably supported (via 6) at the stationary component with the opening of the main oil channel extending opposite (opening of 4e in “a” is considered extending opposite to the offset section of 5) in the axial direction to the offset section of the second output shaft, the oil channel for the bearing of the first output shaft being fluidly connected to the main oil channel via the oil volume (4e and 5b are connected by “a”); and wherein the opening of the main oil channel is covered (5c covers the opening of 4e in the radial direction) in the radial direction by the offset section of the second output shaft. Allowable Subject Matter Claims 14-22 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
