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 .
Claim Objections
Claim objected to because of the following informalities:
Claim 1, line 9 reads “(f” and should read –of--
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.
Claims 1-2, 5 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Clauss (DE 102014219049 A1).
Regarding claim 1, Clauss discloses a forage harvester (10) cracker unit drive assembly (see fig. 3) for driving a first cracker roller (28) and a second cracker roller (28’), the drive assembly comprising a drive pulley (60), a tension pulley (130), a first cracker pulley (84) associated with the first cracker roller, a second cracker pulley (86) associated with the second cracker roller, a guide pulley (126), and a drive belt (62) drivingly connecting each of these pulleys, the drive assembly further comprising a guide pulley adjustment apparatus (134, 124) for adjusting the position of the guide pulley with respect to the second cracker pulley, wherein the guide pulley adjustment apparatus comprises a rotatable body (134) comprising a first axial portion connected to a first side of a central region (f the rotatable body and a second axial portion connected to a second side of the central region, the guide pulley being mounted for rotation about the second axial portion; and wherein a central axis of the first axial portion and a central axis of the second axial portion are offset from one another such that rotation of the adjustment apparatus about the central axis of the first axial portion displaces the guide pulley about a pivot axis which is offset from the axis of rotation of the guide pulley (see fig. 3-4).

Regarding claim 2, Clauss discloses a cracker unit drive assembly according to claim 1, wherein the tension pulley (130) is located to act on the drive belt between the drive pulley (60) and the first roller pulley (see fig. 3-4).
Regarding claim 5, Clauss discloses a forage harvester (10) comprising a forage harvester frame (see fig. 1-2) and a forage harvester cracker unit (28, 28’) including a cracker unit drive assembly of claim 1, wherein the guide pulley adjustment apparatus is mounted to the forage harvester frame.
Claim Rejections - 35 USC § 103
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.
Claims 1, 5-6 are rejected under 35 U.S.C. 103 as being unpatentable over Van Vooren (US 20060089223 A1) in view of Baljozovic (US 11353092 B2).
Regarding claim 1, Van Vooren discloses a forage harvester (not shown, paragraph 0015) cracker unit drive assembly () for driving a first cracker roller (not shown, paragraph 0016) and a second cracker roller (not shown, paragraph 0016), the drive assembly comprising a drive pulley (18), a tension pulley (12), a first cracker pulley (14) associated with the first cracker roller, a second cracker pulley (16) associated with the second cracker roller, a guide pulley (20), and a drive belt (10) drivingly connecting each of these pulleys, the drive assembly further comprising a guide pulley adjustment apparatus (belt tensioning mechanism 28, 22, 24, 46, 50) for adjusting the position of the guide pulley with respect to the second cracker pulley (paragraphs 17-22).
Van Vooren does not disclose wherein the guide pulley adjustment apparatus comprises a rotatable body comprising a first axial portion connected to a first side of a central region of the rotatable body and a second axial portion connected to a second side of the central region, the guide pulley being mounted for rotation about the second axial portion; and wherein a central axis of the first axial portion and a central axis of the second axial portion are offset from one another such that rotation of the adjustment apparatus about the central axis of the first axial portion displaces the guide pulley about a pivot axis which is offset from the axis of rotation of the guide pulley.
Baljozovic discloses a pulley (120) and a pulley adjustment apparatus comprising a rotatable body (114) comprising a first axial portion (114c) connected to a first side of a central region of the rotatable body and a second axial portion (114a) connected to a second side of the central region, the guide pulley being mounted for rotation about the second axial portion; and wherein a central axis of the first axial portion and a central axis of the second axial portion are offset from one another such that rotation of the adjustment apparatus about the central axis of the first axial portion displaces the guide pulley about a pivot axis which is offset from the axis of rotation of the guide pulley (see fig. 5, col. 6 lines 34-56).
It would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to have replaced the guide pulley adjustment apparatus of Van Vooren for that of Baljozovic, as they are art recognized equivalent means of adjusting the tension of a belt via a pulley.
Regarding claim 5, Van Vooren, of the resultant combination, discloses a forage harvester (not shown, paragraph 0015) comprising a forage harvester frame (40) and a forage harvester cracker unit (not shown, paragraph 0016) including a cracker unit drive assembly of claim 1, wherein the guide pulley adjustment apparatus is mounted to the forage harvester frame.
Regarding claim 6, Baljozovic, of the resultant combination, discloses a method of adjusting the circumferential contact area of a drivebelt with the second cracker pulley in a forage harvester cracker unit drive assembly according to claim 1 comprising the steps of releasing the guide pulley adjustment apparatus, adjusting the angular position of the guide pulley with respect to the second cracker pulley and securing the guide pulley apparatus in position (col. 6 lines 34-56, fastener 130 allows the tensioning assembly to release the tensioner for angular adjustment before resecuring).
Response to Arguments
Applicant’s arguments have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument.
Conclusion
Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
