Regarding Claim 10, Hodgson discloses: construction machine characterized by comprising the operation lever according to claim 1 (Fig. 1). 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 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 of this title, 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) 5, 6, and 8 is/are rejected under 35 U.S.C. 103 as being unpatentable over Hodgson (US 20030152452 A1) in view of Reusing (DE 10043179 A1). Regarding Claim 5, Hodgson teaches: a swing limiting portion capable of limiting an operation of a swing operation of the boom by the swing operation portion [0038]. Hodgson does not teach: a swing lock portion capable of locking an operation of a swing operation of the boom by the swing operation portion. Reusing teaches: An operation lever (1) for a construction machine [0001], characterized by integrally connecting: a boom operation portion (6) capable of operating a movement operation of a boom with respect to a machine body [0030 & 0037]; an arm operation portion (8) capable of operating a movement operation of an arm with respect to the boom [0030 & 0037]; an attachment operation portion (10) capable of operating an operation of an attachment [0031 & 0032 & 0037 & 0040 & 0043]; a swing operation portion (4) capable of operating a swing operation of the boom with respect to the machine body [0029 & 0030 & 0037]; and a swing lock portion capable of locking an operation of a swing operation of the boom by the swing operation portion [0042]. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the operation lever for a construction machine having a boom operation portion, arm operation portion, attachment operation portion, and swing operation portion with a swing limiting portion capable of limiting an operation of a swing operation of the boom by the swing operation portion taught by Hodgson with the operation lever for a construction machine having a boom operation portion, arm operation portion, attachment operation portion, and swing operation portion with a swing lock portion capable of locking an operation of a swing operation of the boom by the swing operation portion taught by Reusing in order to provide a means for adjustably limiting the operating range of the construction machine in order to prevent damage to the machine or its surroundings due to unintentional contact. Regarding Claim 6, Hodgson does not teach: an electromagnetic-load device capable of adjusting an operation load of at least one of the boom operation portion, the arm operation portion, the attachment operation portion, and the swing operation portion. Reusing teaches: An operation lever (1) for a construction machine [0001], characterized by integrally connecting: a boom operation portion (6) capable of operating a movement operation of a boom with respect to a machine body [0030 & 0037]; an arm operation portion (8) capable of operating a movement operation of an arm with respect to the boom [0030 & 0037]; an attachment operation portion (10) capable of operating an operation of an attachment [0031 & 0032 & 0037 & 0040 & 0043]; a swing operation portion (4) capable of operating a swing operation of the boom with respect to the machine body [0029 & 0030 & 0037]; and an electromagnetic-load device capable of adjusting an operation load of at least one of the boom operation portion, the arm operation portion, the attachment operation portion, and the swing operation portion [0013 & 0014 & 0040]. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the operation lever for a construction machine having a boom operation portion, arm operation portion, attachment operation portion, and swing operation portion relying on operator observation for feedback taught by Hodgson with the operation lever for a construction machine having a boom operation portion, arm operation portion, attachment operation portion, and swing operation portion with an electromagnetic-load device capable of adjusting an operation load of at least one of the boom operation portion, the arm operation portion, the attachment operation portion, and the swing operation portion taught by Reusing in order to provide force feedback to the operator when the system encounters resistance to prevent damage to the system or surrounding environment due to interference or contact in the system which the operator is unable to or fails to observe thereby providing redundancy in the feedback system. Regarding Claim 8, Hodgson teaches: the swing operation portion is constituted rotatably in a right-left direction with respect to a base portion of the operation lever [0029 & 0031 & 0034 & 0037 & 0039 & 0046]; the boom operation portion is constituted rotatably with respect to the swing operation portion in a rotating direction in a front-rear direction as the first operation direction [0029 & 0031 & 0034 & 0035 & 0037 & 0038]; the arm operation portion is constituted rotatably with respect to the boom operation portion in a rotation direction in the front-rear direction as the second operation direction [0029 & 0031 & 0032 & 0034 & 0035 & 0036 & 0037 & 0038], and the attachment operation portion is constituted slidably with respect to the arm operation portion in a sliding direction in the front-rear direction as the third operation direction [0032]. Hodgson does not teach: the boom operation portion is constituted slidably with respect to the swing operation portion in a sliding direction in a front-rear direction as the first operation direction; Reusing teaches: An operation lever (1) for a construction machine [0001], characterized by integrally connecting: a boom operation portion (3) capable of operating a movement operation of a boom with respect to a machine body [0045 & 0046 & 0047]; an arm operation portion (26 & 28) capable of operating a movement operation of an arm with respect to the boom [0045 & 0046 & 0047]; an attachment operation portion (30) capable of operating an operation of an attachment [0046 & 0047]; the boom operation portion is constituted slidably with respect to the swing operation portion in a sliding direction in a front-rear direction as the first operation direction (Fig. 3) [0045 & 0046 & 0047]; and the attachment operation portion is constituted slidably with respect to the arm operation portion in a sliding direction in the front-rear direction as the third operation direction (Fig. 3) [0046 & 0047]. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the operation lever for a construction machine having a boom operation portion, arm operation portion, attachment operation portion, and swing operation portion where the boom operation portion is constituted rotatably with respect to the swing operation portion in a rotating direction in a front-rear direction as the first operation direction, the arm operation portion is constituted rotatably with respect to the boom operation portion in a rotation direction in the front-rear direction as the second operation direction, and the attachment operation portion is constituted slidably with respect to the arm operation portion in a sliding direction in the front-rear direction as the third operation direction taught by Hodgson with the operation lever for a construction machine having a boom operation portion, arm operation portion, attachment operation portion, and swing operation portion where the boom operation portion is constituted slidably with respect to the swing operation portion in a sliding direction in a front-rear direction as the first operation direction and the attachment operation portion is constituted slidably with respect to the arm operation portion in a sliding direction in the front-rear direction as the third operation direction taught by Reusing in order to provide a means of controlling a construction machine utilizing sliding components to accurately impart movement of the slidingly movable components.
