Office Action

§102 §103 §112
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 . Drawings The drawings are objected to under 37 CFR 1.83(a). The drawings must show every feature of the invention specified in the claims. Therefore, the “umbilical tether drive”, “drive element” and “drive motor”, as required in claim 1; “at least one protrusion” engaging with the spaced apart annular disk, as required in claim 2; protrusions engaging catch structures, as required in claim 3; and the “flexible interconnected links”, as required in claim 17, must be shown or the feature(s) canceled from the claim(s). No new matter should be entered. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 8, 10, 13 and 14 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Regarding claim 8, recited “a second sensor” and “second control unit” is indefinite because how could be a second sensor and a second control unit if a first sensor and a first control unit are not required. Regarding claim 10, recited “a second power supply” is indefinite because how could be second power supply without a first power supply. Regarding claim 13, recited “a third control unit” is indefinite because how could be a third control unit without first and second control units. Regarding claim 14, the claim is indefinite because inherits the same issues of claim 13 because of its dependency. 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 21-23 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Roscoe (US 2009/0014036). Claim 21 Roscoe discloses a system capable of controlling temperature and humidity conditions in a pipe, the system comprising an air conditioning apparatus configured to discharge air into a pipe; at least one sensor configured to detect temperature and/or air velocity; and a control unit/arrangement capable to adjust the air conditions in the pipe based on the data from the at least one sensor (see [0029]). Claim 22 Roscoe further discloses the control unit is configured to adjust the temperature of the air discharged into the pipe, and/or the velocity of the air discharge into the pipe (see [0029], [0048] and abstract). The control blowing means is capable to adjust and detect air velocity. Claim 23 Roscoe further discloses the control unit is configured to adjust the air velocity in the pipe by controlling the dimension of an orifice positioned in the pipe. Roscoe discloses the control valve arrangement that open or close valve (see [0042]). 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, 3-5, 8, 9 and 12-20 are rejected under 35 U.S.C. 103 as being unpatentable over Motzo (US 2016/0256903) in view of Zink (US 2015/0000760) (both references provided by the applicant). Claim 1 Motzo discloses a system for positioning an umbilical supply line, the system comprising an umbilical supply line (62); a plurality of spaced apart annular disk assemblies (61), wherein each annular disk assembly defines an aperture (defined by area of the disk where the umbilical supply line passes through) through which the umbilical supply line is positioned (see figure 6); and a reeling apparatus/winch-pulled tool (see [0037]) comprising an axle that receives the umbilical supply line therearound. Motzo does not disclose an umbilical tether drive system comprising at least one drive element driven by a drive motor, as required. However, Zink discloses an apparatus for insertion into a tank comprising an umbilical tether drive (102) comprising a drive element (146) driven by a motor (144), wherein the drive element has plurality of protrusions (140) (see [0032] and [0033]). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Motzo including a drive element driven by a drive motor as taught by Zink for self-displacement of the umbilical supply line. Claim 3 Zink further discloses upon movement of the drive element, at least one of the plurality of protrusions (140) engage one of a plurality of catch structures (138) positioned on the umbilical supply line (see [0032]). Claim 4 Zink further discloses the umbilical tether drive system further comprises a power supply (114); and a control unit (166) that communicates with the power supply and at least one drive motor (see [0049], [0032] and [0050]). Claim 5 Zink further discloses the umbilical tether drive system further comprises at least one sensor/actuator (166) that detects/controls a position/angle of the umbilical supply line, or direction of movement of the umbilical supply line (see [0049]). Claim 8 Motzo further discloses a sensor capable to detect position of a centralizer in a pipe, or to adjust air conditions in the pipe based on the data from the sensor (see [0061]-[0063]). Claim 9 Motzo further discloses a centralizer (see [0077]). Claim 12 Motzo further discloses the centralizer further comprises an application device for dispensing a fluid (see [0092]). Claim 13 Motzo further discloses a control unit capable to control the movement of the centralizer (see [0062]-[0064]). Claim 14 Motzo further discloses the control unit of the drive system and the control unit are capable to synchronize deployment and retraction/position of the umbilical supply line and the centralizer (see [0062]-[0067]). Claim 15 Motzo further discloses the plurality of spaced apart annular disk assemblies (61) further comprise a plurality of angularly spaced rollers mounted generally on and extending radially therefrom an outer perimeter of each of the annular disk assemblies (see figure 6). Claim 16 Motzo further discloses the plurality of spaced apart annular disk assemblies are positioned along the length of the umbilical supply line (see figure 6). Claim 17 Motzo further discloses a plurality of flexible interconnected links (defined by connections between the disk assemblies as shown in figure 6) that couple two adjacent annular disk assemblies. Claim 18 Motzo further discloses the reeling apparatus/winch-pulled tool is configured to rotate such that when the reeling apparatus is rotated in a first direction, the umbilical supply line is unwound during deploying of the umbilical supply line and when the reeling apparatus is rotated in a second direction, the umbilical supply is positioned around the reel during retracting of the umbilical supply line. The normal function of a winch-pulled tool is to unwound a line attach and to wound around a reel or the winch-pulled tool. Claim 19 Motzo further discloses the system positions the umbilical supply line in a pipe (defined by pipe that encloses the umbilical supply line) (see figure 6). Claim 20 Motzo discloses a system for positioning an umbilical supply line, the system comprising an umbilical supply line (62) (see figure 6) and a reeling apparatus/winch-pulled tool (see [0037]) comprising an axle that receives the umbilical supply line therearound. Motzo does not disclose the umbilical supply line including a plurality of catch structures positioned on, affixed to, and/or connected to the umbilical supply line; and an umbilical tether drive system comprising at least one drive element driven by a drive motor. However, Zink discloses an apparatus for insertion into a tank comprising an umbilical tether drive (102) comprising a drive element (146) driven by a motor (144), wherein the drive element has plurality of protrusions (140) (see [0032] and [0033]). Zink further discloses the drive element comprising plurality of protrusions (140) complementary in shape with plurality of catch structures (138) positioned on the umbilical supply line (see [0032]). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Motzo including a drive element driven by a drive motor as taught by Zink for self-displacement of the umbilical supply line. After Motzo is modified by Zink, when the drive element is driven by the drive motor, the umbilical tether drive system will deploy and/or retract the umbilical supply line from the reeling apparatus. Allowable Subject Matter Claims 2, 6, 7 and 11 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.
