The boring machine as claimed in claim 18, wherein the translational guiding device is integrated into the frame, and the movable member is disposed in the frame.(based upon broadest reasonable interpretation, integration into the frame is interpreted as being structurally supported within the structure of the body ( which includes the cage) where in the cylinder 44 is the translational guiding device, ) 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 (i.e., changing from AIA to pre-AIA ) 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, 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. JPS6245831 – Nippon Claim(s) 29 and 30 are rejected under 35 U.S.C. 103 as being unpatentable by JPH10195924 – Toru et al. hereinafter as TORU in view of Official Notice Regarding Claim 29 TORU discloses claim 21: TORU discloses using a hydraulic jack but not explicitly a hydraulic motor for running the mill drums. OFFICIAL NOTICE 29. The boring machine as claimed in claim 18, wherein the first motor is hydraulic.(where in hydraulic motors are a well known drive unit) It would be obvious to one of ordinary skill in the art before the effective filling date of the applicants invention for TORI disclosing of a drilling device to include the motor to be hydraulic as taught by official notice. Regarding Claim 30 TORU discloses of utilizing hydraulics in the milling drum machine, However does not explicitly disclose a swivel joint. OFFICIAL NOTICE 30. The boring machine as claimed in claim 18, wherein the frame further includes a swivel joint which is connected to the body by way of a removable element.(Wherein a swivel join, rotary union, center joint are fundamental to excavator operation) It would be obvious to one of ordinary skill in the art before the effective filling date of the applicants invention for TORI disclosing of a Milling drum excavator device to include swivel joint as taught by official notice. Allowable Subject Matter Claims 25, 27, 31 and 32 are allowable TORU disclose the boring machine as recited in the rejection above. However does not explicitly disclose wherein, considered along a transverse direction perpendicular to the longitudinal direction and to the first pivoting axis, the first and second axes of pivoting are located between the first and second axes of pivot, wherein the first and second supports are shaped to come into contact with one another when the boring machine is in the retracted position, the stop device consisting of stop faces disposed face-to-face on each of the first and second supports, wherein the movable member is housed in the translational guiding device such as to form together a sliding coupling, wherein the translational guiding device includes two parallel rails extending along the longitudinal direction of the body and together delimiting a passage for the movable member and wherein the translational guiding device is separate from the actuating device. Such modification would require too significant modifications and would constitute an improper degree of hindsight reasoning. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
