§102 §103
DETAILED ACTION Notice of Pre-AIA or AIA Status 1. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claim Rejections - 35 USC § 102 2. 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. 3. 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. 4. Claim 22 is rejected under 35 U.S.C. 102(a)(1) as being anticipated by Sauer et al. (US 5878548 A). Regarding claim 22, Sauer et al. discloses “ A corner protector (11; Annotated Fig 2) having a base (33; Annotated Fig 2) and a top (25; Annotated Fig 2), the base comprising a sidewall having an inner surface and an outer surface, a plurality of fingers (51-53; Annotated Fig 2) disposed on the sidewall surface and extending upwardly from the sidewall surface, each finger forming a cable receiving space (As seen in Annotated Fig 2) between the finger and a lateral edge of said sidewall, wherein the top joins the sidewall to form a corner (45; Annotated Fig 2) at the first sidewall end, wherein the sidewall spans from the top corner to a second sidewall end opposite the corner, and wherein at least one finger is disposed closest to one of the said first or second sidewall ends, and wherein said at least one finger is supported on a finger base (55; Annotated Fig 2), and wherein said sidewall outer surface spans from said sidewall lateral edge to the finger base of the at least one finger disposed closest to the said at least one of said first sidewall end or said second sidewall end.” PNG media_image1.png 691 816 media_image1.png Greyscale Claim Rejections - 35 USC § 103 6. 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. 7. Claims 1-21 are rejected under 35 U.S.C. 103 as being obvious over Sauer et al. (US 5878548 A) in view of Lonnberg et al. (US 10967778 B2). Regarding claim 1, Sauer et al. teaches “A corner protector (11; Annotated Fig 2) for protecting the top corners (13; Annotated Fig 2) of a stack (15; Annotated Fig 2) of lumber (17; Annotated Fig 2) or other cargo from being indented or frayed by tie-down cables (19; Annotated Fig 2) in railroad freight cars (5; Fig 1), comprising: a top wall (25; Annotated Fig 2), a sidewall (33; Annotated Fig 2) connected at its top to the top wall at a substantially right angle so that the sidewall is adapted to contact the side of the stack of lumber or other cargo and the top wall is adapted to contact the top of the stack of lumber or other cargo, said sidewall having an inner sidewall surface and an outer sidewall surface, said top wall joining the sidewall and forming a corner (45; Annotated Fig 2) with the sidewall, cable retention fingers (51-53; Annotated Fig 2) mounted on the sidewall for capturing and retaining a tie-down cable (Col. 3 Line 38- Col. 2 Line 2) … wherein said cable receiving space (As seen in Annotated Fig 2) is defined in part by said outer sidewall surface, and wherein said outer sidewall surface defining said cable receiving space spans from the attached end of the at least one finger to a lateral edge of said sidewall, wherein the cable receiving space defines a cable receiving zone that spans unobstructed between the finger attached end and the sidewall lateral edge.” Sauer et al. fails to teach “wherein at least one of said fingers has a free end and an attached end, said attached end attaching said at least one finger to said sidewall, wherein the at least one finger has a camming surface sloping upwardly toward the free end, wherein said finger free end of the at least one finger is disposed at a height above the outer sidewall surface and defines a cable receiving space between the outer sidewall surface and the finger free end” However, Lonnberg et al. annotated Fig. 2 teaches a cam surface (160; Annotated Fig 2), sloping upward with a free end (161; Annotated Fig 2) raised above the side wall (118; Annotated Fig 2) outer surface, creating a cable receiving space, as seen in Lonnberg et al. annotated Fig. 2. Therefore, it would be obvious to someone of ordinary skill in the art, prior to the effective filing date of the claimed invention to have combined the structure of Sauer et al. and replaced one of three fingers (53; Sauer et al. Annotated Fig 2) with the cam-sloped surface of Lonnberg et al. with a reasonable expectation of success for increasing ease of installation.

Col. 2 Line 59- Col. 3 Line 5).” With respect to claim 16, the combination of Sauer et al. and Lonnberg et al. teaches “The protector (11; Sauer et al. Annotated Fig 2) of claim 2, wherein the cable receiving space (As seen in Sauer et al. Annotated Fig 2) has a lower boundary that is defined by the substantially planar outer sidewall surface (33; Sauer et al. Annotated Fig 2).” In reference to claim 17, Sauer et al. teaches “A corner protector (11; Sauer et al. Annotated Fig 2) and railroad car (5; Sauer et al. Fig 1) combination for protecting the top corner (13; Sauer et al. Annotated Fig 2) of a stack (15; Sauer et al. Annotated Fig 2) of lumber (17; Sauer et al. Annotated Fig 2) or other cargo on a railroad car from being indented or frayed by tie-down cables (19; Sauer et al. Annotated Fig 2), comprising: a railroad freight car, a stack of lumber or other cargo on the railroad freight car, a tie-down cable having each end mounted on the freight car, and a corner protector comprising: a top wall (25; Sauer et al. Annotated Fig 2), a sidewall (33; Sauer et al. Annotated Fig 2) connected at its top to the top wall at a substantially right angle so that the sidewall is adapted to contact the side of the stack of lumber or other cargo and the top wall is adapted to contact the top of the stack of lumber or other cargo, said sidewall having an inner sidewall surface and an outer sidewall surface, said top wall joining the sidewall and forming a corner (45; Sauer et al. Annotated Fig 2) with the sidewall, cable retention fingers mounted on the sidewall for capturing and retaining (Sauer et al. Col. 3 Line 38 - Col. 4 Line 2) a tie-down cable… wherein said cable receiving space is defined in part by said outer sidewall surface, and wherein said outer sidewall surface defining said cable receiving space extends from the attached end of the at least one finger to a lateral edge of said sidewall. whereby, when the protector is mounted on the corner of the stack of lumber or other cargo, the lumber or other cargo is protected against being contacted and indented by the tie- down cable, the cable is protected against wearing and fraying caused by contacting the corner of the stack of lumber or other cargo (Sauer et al. Col 2 Lines 59-63), and the protector may be installed without disconnecting the cable by loosening the cable and inserting the protector under the cable and mounting the protector on the top corner of the stack of lumber, and then tightening the cable (Sauer et al. Col 2 Lines 44-52).” Sauer et al. fails to teach “…wherein at least one of said fingers has a free end and an attached end, said attached end attaching said at least one finger to said sidewall, wherein the at least one finger has a camming surface sloping upwardly toward the free end, wherein said finger free end of the at least one finger is disposed at a height above the outer sidewall surface and defines a cable receiving space between the outer sidewall surface and the finger free end…” However, Lonnberg et al. annotated Fig. 2 teaches a cam surface (160; Annotated Fig 2), sloping upward with a free end (161; Annotated Fig 2) raised above the side wall (118; Annotated Fig 2) outer surface, creating a cable receiving space, as seen in Lonnberg et al. annotated Fig. 2. Therefore, it would be obvious to someone of ordinary skill in the art, prior to the effective filing date of the claimed invention to have combined the structure of Sauer et al. and replaced one of three fingers (53; Sauer et al. Annotated Fig 2) with the cam-sloped surface of Lonnberg et al. with a reasonable expectation of success for increasing ease of installation. Regarding claim 18, Sauer et al. teaches “A method of protecting the top corners (13; Sauer et al. Annotated Fig 2) of a stack (15; Sauer et al. Annotated Fig 2) of lumber (17; Sauer et al. Annotated Fig 2) or other cargo from indentations from a tie-down cable (19; Sauer et al. Annotated Fig 2) in a railroad freight car (5; Sauer et al. Fig 1) comprising the steps of: a) loading a stack of lumber or other cargo on the railroad freight car, b) fastening both ends of tie-down cable on the railroad freight car, c) contacting the load of lumber or other cargo with the tie-down cable, and d) providing a corner protector comprising: i) a top wall, ii) a sidewall connected at its top to the top wall at a substantially right angle so that the sidewall is adapted to contact the side of the stack of lumber or other cargo and the top wall is adapted to contact the top of the stack of lumber or other cargo, iii) said sidewall having an inner sidewall surface and an outer sidewall surface, iv) said top wall joining the sidewall and forming a corner with the sidewall, v) cable retention fingers mounted on the sidewall for capturing and retaining (Col. 5 Line 62- Col. 6 Line 24) a tie-down cable…” Sauer et al. fails to teach “…wherein at least one of said fingers has a free end and an attached end, said attached end attaching said at least one finger to said sidewall, wherein the at least one finger has a camming surface sloping upwardly toward the free end, wherein said finger free end of the at least one finger is disposed at a height above the outer sidewall surface and defines a cable receiving space between the outer sidewall surface and the finger free end; vii) wherein said cable receiving space is defined in part by said outer sidewall surface, and wherein said outer sidewall surface defining said cable receiving space extends from the attached end of the at least one finger to a lateral edge of said sidewall. e) loosening the tie-down cable on the railroad freight car, f) placing the corner protector on the top corner of the stack of lumber under the tie-down cable, g) positioning the tie-down cable through said cable receiving space; h) rotating the protector in a direction so that the tie-down cable engages and is moved along the camming surface of the at least one finger, and so that the tie-down cable is secured by the plurality of cable retention fingers.” However, Lonnberg et al. Fig 7-9 teach when the tie-down cable (103; Lonnberg et al. Fig 7) is placed in the cable receiving space (109; Lonnberg et al. Fig 7), between two fingers (105 &107; Lonnberg et al. Fig 7), and the user rotates the corner protector (104; Lonnberg et al. Fig 7), the cable will slide over the cam-sloped surface (160; Lonnberg et al. Fig 7) and become secured by a plurality of fingers. Therefore, it would be obvious to someone of ordinary skill in the art, prior to the effective filing date of the claimed invention to have combined the structure of Sauer et al. and replaced one of three fingers (53; Sauer et al. Annotated Fig 2) with the cam-sloped surface of Lonnberg et al. with a reasonable expectation of success for increasing ease of installation. With respect to claim 19, the combination of Sauer et al. and Lonnberg et al. teaches “The method of claim 18, wherein rotating the protector (104; Lonnberg et al. Fig 7) rotates the tie-down cable (103; Lonnberg et al. Fig 7) through the space defined between a lateral edge of the sidewall (118; Lonnberg et al. Fig 7) and the attached end of the at least one finger (Lonnberg et al. Col 7 Lines 4-9).” In reference to claim 20, the combination of Sauer et al. and Lonnberg et al. teaches “The method of claim 18, further including tightening down the tie-down cable (19; Sauer et al. Annotated Fig 2) to hold the protector (11; Sauer et al. Annotated Fig 2), in place on the top corner (13; Sauer et al. Annotated Fig 2) of the stack (15; Sauer et al. Annotated Fig 2) of lumber (17; Sauer et al. Annotated Fig 2) (Sauer et al. Col. 6 Lines 64-65).” Regarding claim 21, the combination of Sauer et al. and Lonnberg et al. teaches “The method of claim 19, wherein the outer sidewall (33; Sauer et al. Annotated Fig 2) surface defining the cable receiving space is substantially planar in the area between the attached end of the at least one finger (51-53; Sauer et al. Annotated Fig 2) and the sidewall lateral edge.” Conclusion 9.
