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 because: The following recited limitations do not have reference numerals in the specification that can be found in the drawings: “Boom section” (first, second, third and fourth) “Extension system” (first and second) “Tensile member” (first, second, third and fourth) “Wall” (several walls recited in the claims while there is no mention for any wall in the specification) “Retraction system” (first and second) “First portion” and “Second portion” of any element. “Flexible chain” The drawings are also objected to for general clarity issues throughout the figures; whereas none-limiting examples: flexible segment is being referred to with both numerals 34 and 36, loose ends of ropes 30 and 32 in fig. 6 are not understood as to their function/operation, area where ends of ropes 26 attach to section 13 appear to be the same as that piston 24 attaches to section 13. 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. Specification The specification is objected to as failing to provide proper antecedent basis for the claimed subject matter. See 37 CFR 1.75(d)(1) and MPEP § 608.01(o). Correction of the following is required: The following limitations positively recited, required and pivotal to the invention either does not have mentioned in the specification or is mentioned only in the background with no reference that can be found in the drawings in the body of the description: “Boom section” (first, second, third and fourth) “Extension system” (first and second) “Tensile member” (first, second, third and fourth) “Wall” (several walls recited in the claims while there is no mention for any wall in the specification) “Retraction system” (first and second) “First portion” and “Second portion” of any element. “Flexible chain” 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 12-31 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. In light of the significant number of limitations missing in the speciation, it is submitted that failure to find those limitations led to indefinite claims. To clarify, while the four boom sections can be understood from the specifications and drawings, failure to point out the first and second tensile member in light of the presence of several ropes make the claim indefinite as to what are the components being claimed. Similarity, where there is no mention throughout the specification for any wall, first or second portions of any of the claimed elements, a flexible chain, or any mention for an extension or a retraction system, resulted in that the application does not only include drawings objections for missing illustration of few limitations, but lack of being able to find the limitations in the specification and track the claimed elements in the drawings submitted, which is necessary for the understanding of the claims and for the applicant to particularly point out and distinctly claim the subject matter which the inventor regards as the invention. To yet further clarify, as none limiting examples, ropes 26 best assumed to be the first tensile member appear to be configured to move third section with respect to the first section (not the second as recited in line 11-12 of claim 12), and similarly, ropes 28 best assumed to be the second tensile member appear to be configured to move fourth section with respect to the second section (not the third as recited in line 14-15 of claim 12). As further example, none of the ropes appear to be between side walls of the different boom sections, instead they appear to be between inner walls of the boom section i.e., encompassed within interior of sections, and extends through other sections. The claimed pipe in claim 26 according to paragraphs [0047] and [0049], are coupled to 3rd and 4th sections and 1st and 3rd sections respectively, not 1st and 4th as recited in lines 10-11 of claim 26. Dependent claims are rejected at least for depending from a rejected claim. Claims are examined as best understood. Claim Rejections - 35 USC § 102 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 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.

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 20, 24-25 and 27-29 are rejected under 35 U.S.C. 103 as being unpatentable over Dupre as applied to claims 23 and 26 respectively above, and further in view of Magni, US (2015/0151954). In regards to claim 20 Dupre does not disclose the first tensile member is a rope. Magni teaches tensile member is a rope (rope driving means 110 and 120) for the purpose of driving sections of a boom. Therefore, before the effective filing date of the claimed invention, it would have been obvious to a person of ordinary skill in the art to substitute the chains of Dupre with ropes as taught by Magni, for the predictable result with reasonable expectation of success i.e., to provide for more flexible drive means not prone to rusting, and as suggested by Magni where ropes are used interchangeably throughout the Magni reference. In regards to claims 24 and 27 Dupre does not disclose a pulley coupled to the second boom section, and a segment of the pipe is wound around the pulley. Magni teaches a pulley (212; fig. 2) coupled to the second boom section (section to which 212 equated to second boom section of Dupre), and a segment of the pipe (portion of 211; fig. 2) is wound around the pulley (212; as shown in fig. 2; Magni). Therefore, before the effective filing date of the claimed invention, it would have been obvious to a person of ordinary skill in the art to utilize the pulley taught by Magni to facilitate turning sections of the pipe of Dupre for the predictable result with reasonable expectation of success i.e., to minimize friction and stress points experienced at bends in the pipe. Further with regards to claims 24 and 27 Dupre discloses a third segment of the pipe extends within the second boom section (within section 40 as shown in fig. 4; Dupre). In regards to claim 25 Dupre discloses a flexible chain (hose guide 132; fig. 4) receiving a fourth segment of the pipe (segment of the pipe with portions of 132) and extending within the fourth boom section (within 60 as shown in fig. 4), wherein a first end portion of the flexible chain is coupled to the third boom section (directly or indirectly at least via hose carrier housing 110), and wherein a second end portion of the flexible chain is coupled to the fourth boom section (directly or indirectly at least via hose carrier housing 110). In regards to claim 28 Dupre discloses a flexible chain (hose guide 132; fig. 4) receiving a fourth segment of the pipe (segment of the pipe with portions of 132), wherein a first end portion of the flexible chain is coupled to the third boom section (directly or indirectly at least via hose carrier housing 110),, and wherein a second end portion of the flexible chain is coupled to the fourth boom section (directly or indirectly at least via hose carrier housing 110),. In regards to claim 29 Dupre discloses the flexible chain extends within the fourth boom section (as shown in fig. 4).
