Office Action

§103
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 . The amendment filed 5/18/2026 has been entered. 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. Claims 1-20 are rejected under 35 U.S.C. 103 as being unpatentable over Dang (US 2015/0090171). With respect to claims 1, 15 and 16, Dang discloses a mechanical joint and inherent method configured to provide an articulated connection between a first member/vessel 1 and a second member/ mooring 4, comprising: a first bearing block 20 and a second bearing block 20 configured to be disposed on the vessel (see Figs. 4, 7A-B), a gimbal table 8 that defines an aperture therethrough, wherein an upper surface of the gimbal table defines a first bearing surface and a second bearing surface on a first pair of opposing sides of the gimbal table (see Figs. 6A-B); a first trunnion 10 and a second trunnion 10 disposed on a second pair of opposing sides of the gimbal table; and an arm 11 having a first end and a second end, wherein a third trunnion and a fourth trunnion 9 are each disposed toward the second end of the arm, wherein: the third trunnion and the fourth trunnion are aligned with a first axis 6, the first trunnion and the second trunnion are aligned with a second axis 5, the first axis and the second axis are substantially orthogonal or substantially perpendicular with respect to one another (see Fig. 5B), the third trunnion and the first bearing surface are engaged with one another, the fourth trunnion and the second bearing surface are engaged with one another, the arm is rotatable relative to the gimbal table about the first axis 6, and at least a portion of the arm is disposed through the aperture/ opening defined by the gimbal table (See Figs. 4 and 7 A-B, Para [0030]-[0041]). As to further limitations of claim 16, Dang discloses the mechanical joint further comprising an arm having a first end and a second end, wherein a third trunnion and a fourth trunnion are each disposed toward the second end of the arm; a first bearing cap 12 engaged with the third trunnion and attached to the upper surface of the gimbal table; a second bearing cap 12 engaged with the fourth trunnion and attached to the upper surface of the gimbal table 8 (see 6B); a third bearing cap 12 secured to the first bearing block 20; and a fourth bearing cap 12 secured to the second bearing block 20, the third trunnion and the first bearing surface are engaged with one another, and the first trunnion 10 is configured to rotatively engage with the first bearing block 20 and the second trunnion 9 is configured to rotatively engage with the second bearing block; and installing the mechanical joint on the first member (See Figs. 5-10, Para [0031]-[0039]. Dang also discloses the first end of the arm is located on a side of the gimbal table8 that is opposite the upper surface of the gimbal table, and the first end of the arm is configured to connect to the second member/mooring 4 (see Figs.1 & 2 (prior art), Para [0004]). Therefore, in view of Dang’s Figs. 1 and 2, it would have been obvious to one of ordinary skill in the art before the effective filing date to modify the first end of the articulated joint in order to make the articulated joint with the arm interchangeable with easily replacing the first end of the arm of the articulated joint for the mooring when the main connecting part in the articulated joint as taught by Dang was not in use or broken. With respect to claim 2, Dang discloses a connection link disposed on the arm toward the second thereof, wherein the third trunnion and the fourth trunnion are attached to the arm via the connection link (see Figs. 8A-B, Para [0037]). With respect to claim 3, Dang discloses the second end of the arm defines a bore therethrough that is aligned with the first axis, the connection link is disposed through the bore defined by the second end of the arm, and the third trunnion and the fourth trunnion 9 are rigidly connected to the connection link (See Figs. 10A-B, Para [0036]). With respect to claim 4, although Dang does not specifically disclose the connection link is rotatively connected to the arm, it would have been obvious to one of ordinary skill in the art before effective filing date to provide the screw connection to the arm in order to conveniently disassemble the device for repair or storage. With respect to claim 5, Dang discloses a bushing 18 disposed between the connection link and a surface of the bore defined by the second end of the arm (See Figs. 7A-B, Para [0033]). With respect to claim 6, Dang discloses the connection link is rigidly connected to the arm, the third trunnion 9 and the first bearing surface of the body 12, 20 are rotatively engaged with one another, and the fourth trunnion 9 and the second bearing surface of the body 12, 20 are rotatively engaged with one another (See Figs. 7A-B, Para [0033] & [0035]). With respect to claim 7, Dang discloses a first bearing cap12 and a second bearing cap 12, wherein: the first bearing cap is engaged with the third trunnion 9 and attached to the upper surface of the gimbal table 8, and the second bearing cap 12 is engaged with the fourth trunnion 9 and attached to the upper surface of the gimbal table (See Figs. 7A-B, Para [0033]). With respect to claim 8, Dang discloses a first bushing 18 disposed between the third trunnion 9 and the first bearing surface and a third bearing surface defined by the first bearing cap 12, and a second bushing 18 disposed between the fourth trunnion 9 and the second bearing surface and a fourth bearing surface defined by the second bearing cap 12 (See Figs. 7A-B, Para [0033] & [0035]). With respect to claim 9, Dang discloses a first bearing block and a second bearing block 20 configured to be disposed on the first member/vessel 1, wherein the first trunnion 10 is configured to rotatively engage with the first bearing block 20 and the second trunnion 10 is configured to rotatively engage with the second bearing block 20 (See Figs. 7A-B, 8A-B, Para [0033], [0035] &[0039]). With respect to claim 10, Dang discloses comprising a third bearing cap 12 attached to the first bearing block 20 and a fourth bearing cap 12 attached to the second bearing block 20 (See Figs. 7A-B, Para [0033]). With respect to claim 11, Dang discloses the third bearing cap 12 is rotatively engaged with the first trunnion 10 and the fourth bearing cap 12 is rotatively engaged with the second trunnion 10 (See Figs. 7A-B, Para [0033]). With respect to claim 12, Dang discloses a third bushing 18 disposed between the first trunnion 10 and a bearing surface of the body defined by the first bearing block 20 and a bearing surface defined by the third bearing cap 9, and a fourth bushing disposed between the second trunnion and a bearing surface defined by the second bearing block 10 and a bearing surface defined by the fourth bearing cap 12 (See Figs. 7A-B, Para [0033]). With respect to claim 14, Dang discloses the first member is a vessel 1 and the second member is a mooring leg 4 (See Fig. 4, Para [0030]). With respect to claim 17, Dang discloses inherent process comprising attaching the second member/mooring 4 to the first end of the arm 11 (See Fig. 4, Para [0030]). With respect to claim 18, Dang discloses inherent process comprising the first member is a vessel 1 and the second member is a mooring leg 4, and wherein installing the mechanical joint on the vessel 1comprises attaching the first bearing block 20 and the second bearing block 20 to the vessel 1 (See Fig. 4, Para [0030]). With respect to claim 19, Dang discloses a connection link disposed on the arm toward the second trunnion 10, and wherein the third trunnion 9and the fourth trunnion 9 are attached to the arm 11 via the connection link (See Figs. 8A-B, Para [0027] & [0037]). With respect to claim 20, Dang discloses the mechanical joint further comprises: a first bushing 18 disposed between the third trunnion 9 and the first bearing surface and a third bearing surface defined by the first bearing cap 12; a second bushing 18 disposed between the fourth trunnion and the second bearing surface and a fourth bearing surface defined by the second bearing cap 12; a third bushing 18 disposed between the first trunnion and a fifth bearing surface defined by the first bearing block and a seventh bearing surface defined by the third bearing cap 12; and a fourth bushing disposed between the second trunnion and a sixth bearing surface defined by the second bearing block and an eighth bearing surface defined by the fourth bearing cap 12 (See Figs. 7A-B, 8A-B, Para [0033], [0035] &[0039]).
