Office Action

§102 §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 . Specification Applicant is reminded of the proper language and format for an abstract of the disclosure. The abstract should avoid using phrases which can be implied, such as, “The disclosure concerns,” “The disclosure defined by this invention,” “The disclosure describes,” “of the present invention”, and “improved” etc. The abstract of the disclosure is objected to because it contains implied terminology, specifically “of the present invention” in lines 6 and 7 and “improved” in line 1 thereof. A corrected abstract of the disclosure is required and must be presented on a separate sheet, apart from any other text. See MPEP § 608.01(b). Claim Objections Claim 19 is objected to because of the following informality: In line 2 of claim 19, the recitation “a channel bracket 406” appears to be a typographical error and should be corrected to -- a channel bracket--. Appropriate correction is required. 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. Claims 1 and 10-13 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Ames US 4,041,975. Regarding Claim 1, Ames US 4,041,975 discloses an irrigation pipe attachment system (Fig. 1-5; ABSTRACT), wherein the system comprises: a truss angle bracket assembly (102, Fig. 3; col 4, In 20-54); a hitch channel lock assembly (40, Fig. 2; col 2, In 57-64); and a truss rod bracket assembly (25, Fig. 2, Fig. 4; col 2, In 34-42). Regarding Claim 10, Ames US 4,041,975 discloses a hitch channel lock assembly (40, Fig. 2; col 2, In 65-68, col 3, In 1 -15) comprising a hitch ball assembly (52, 56, Fig. 4; col 3, In 22-32) and a hitch channel body (42, Fig. 4). Regarding Claim 11, the hitch ball assembly (52, 56, Fig. 4; col 3, In 22-32) comprises a hitch securing block (52, Fig. 4; col 3, In 22-32) and a hitch ball (56, Fig. 4: col 3, In 22-32). Regarding Claim 12, the hitch ball assembly (52, 56, Fig. 4; col 3, In 22-32) is located within the hitch channel body (42, Fig. 4). Regarding Claim 13, the hitch channel body (42, Fig. 4) comprises a single surface of uniform composition (Fig. 4-5 - the uniform surface of body 42). 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 2-9 are rejected under 35 U.S.C. 103 as being unpatentable over Ames US 4,041,975 in view of Korus et al. US 11,242,947 B2. Regarding Claim 2, Ames US 4,041,975 discloses the system of claim 1, wherein the truss angle bracket assembly (102, Fig. 3; col 4, In 20-54) comprises: a central backing section (105, Fig. 3; col 4, In 41-44); a right extension arm (103, Fig. 2-3; col 4, In 41-44); wherein the right extension arm (103, Fig. 2-3) is connected to the central backing section (105, Fig. 3) via a first bent section (Fig. 3 the bend between 103 and 105); wherein the right extension arm comprises a right securing surface (Fig. 3 the surface of 103); wherein the right securing surface (Fig. 3 the surface of 103) is substantially perpendicular to the central backing section (105, Fig. 3); wherein the position of the right securing surface (Fig. 3 the surface of 103) relative to the central backing section is determined at least in part by a degree of bend in the first bent section (Fig. 3 - the bend between 103 and 105); and a left extension arm (104, Fig. 2-3; col 4, In 41-44), wherein the left extension arm is connected to the central backing section via a second bent section (Fig. 3 the bend between 104 and 105); wherein the left extension arm comprises a left securing surface (Fig. 3 - the surface of 104); wherein the left securing surface (Fig. 3 the surface of 104) is substantially perpendicular to the central backing section (105, Fig. 3); wherein the position of the left securing surface (Fig. 3 the surface of 104) relative to the central backing section is determined at least in part by a degree of bend in the second bent section (Fig. 3 the bend between 104 and 105), but does not specifically teach wherein the right securing surface comprises at least one bolt hole; wherein the left securing surface comprises at least one bolt hole. However, Korus et al.
