PNG media_image6.png 942 1475 media_image6.png Greyscale 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. Claim 23 is rejected under 35 U.S.C. 103 as being unpatentable over Masunaka 6,257,426 in view of Chang 5,676,263. Regarding claim 23, Masunaka has been discussed above but does not explicitly teach wherein said first vertical support comprises a plurality of first sections which are selectively connectable, wherein said plurality of first sections have a length which is less than a distance between said first and second ends of said plurality of shelves. Chang discloses a collapsible rack assembly (Fig 3) wherein a first vertical support (annotated Fig 3 below) comprises a plurality of first sections (annotated Fig 3 below) which are selectively connectable, wherein said plurality of first sections (annotated Fig 3 below) have a length which is less than a distance between a first end (annotated Fig 3 below) and a second end (annotated Fig 3 below) of a plurality of shelves (annotated Fig 3 below). PNG media_image7.png 650 765 media_image7.png Greyscale It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to replace a portion of the first vertical support (Masunaka, annotated Fig 11 below) of Masunaka with a plurality connectable first sections (Chang, annotated Fig 3 above) because the substitution of one known post or post section type for another would have yielded predictable results to one of ordinary skill in the art at the time of the invention. Further the interconnectable first sections (Chang, annotated Fig 3 above) will enable sections of the first vertical support (Masunaka, annotated Fig 11 above) to be easily replaced if they become damaged. PNG media_image8.png 654 1229 media_image8.png Greyscale Claims 25-28 are rejected under 35 U.S.C. 103 as being unpatentable over Masunaka 6,257,426 in view of Hanlon 2022/0287457. It should be noted that there is no support for “a first connector disposed at the first side midpoint region, a second connector disposed at the second side midpoint region, a midline rail extending from the first connector to the second connector; and a first vertical support configured to engage said first connectors of said plurality of shelves and a second vertical support configured to engage said second connectors of said plurality of shelves” in the parent application #17/693101, therefore the current subject matter of claims 21-34 will only be granted the filing date of 03/17/2025. Regarding claim 25, Masunaka has been discussed above but does not explicitly teach wherein the bottom side rail of the midline rail includes a pair of first notches defined between the first connector and the second connector. Hanlon discloses a collapsible rack assembly (Fig 1) comprising a bottom side rail (annotated Fig 6 below) of a widthwise rail (annotated Figs 1 & 6 below) that includes a pair of first notches (annotated Fig 6 below) defined between a first connector (annotated Fig 6 below) and a second connector (annotated Fig 6 below). PNG media_image9.png 827 1533 media_image9.png Greyscale PNG media_image10.png 583 1163 media_image10.png Greyscale It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to form notches (Hanlon, annotated 6 above) on the bottom side rail (Masunaka, annotated Fig 11 above) of the midline rail (Masunaka, annotated Fig 11 above) of Masunaka (which is a widthwise rail (as shown in Masunaka, Fig 11)) in order to make the shelves (Masunaka, annotated Fig 11 above) more aesthetically appealing. Further, the substitution of one known shelf bottom rail shape for another would have yielded predictable results to one of ordinary skill in the art at the time of the invention. Such a modification would have involved a mere change in the shape of a component. A change in shape is generally recognized as being within the level of ordinary skill in the art. Regarding claim 26, modified Masunaka discloses the collapsible rack assembly wherein each first notch (Hanlon, annotated 6 above) is formed by a first segment (Hanlon, annotated 6 below) coupled at a first obtuse angle with a second segment (Hanlon, annotated 6 below), the second segment coupled (Hanlon, annotated 6 below) at a second obtuse angle with a third segment (Hanlon, annotated 6 below), the third segment (Hanlon, annotated 6 below) coupled to one of the first sleeve (Hanlon, annotated 6 above) or the second sleeve (Hanlon, annotated 6 above).

PNG media_image12.png 855 1165 media_image12.png Greyscale Regarding claim 28, modified Masunaka discloses the collapsible rack assembly wherein at least one of the first notches (Hanlon, annotated 6 above) of a first elongated shelf (Masunaka, annotated 11 above) of the plurality of elongated shelves (Masunaka, annotated 11 above) is configured to or capable of allowing at least one of the plurality of end members (Masunaka, annotated 11 above) of another elongated shelf to nest within the first elongated shelf (Masunaka, annotated 11 above) when the collapsible rack assembly is in a collapsed position. Claim 29 is rejected under 35 U.S.C. 103 as being unpatentable over the combination of Masunaka 6,257,426 and Hanlon 2022/0287457; and further in view of Leeds D326,579. Regarding claim 29, modified Masunaka has been discussed above but does not explicitly teach wherein each corner region has a second notch, the second notches being aligned with a corresponding first notch. Leeds discloses a shelf (Fig 1) that is configured to be used in a collapsible rack assembly wherein each corner region (annotated Fig 3 below) of the shelf (Fig 1) has a second notch (annotated Fig 3 below). PNG media_image13.png 436 1260 media_image13.png Greyscale It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to form second notches (Leeds, annotated 3 above) at corner regions (Masunaka, annotated Fig 11 below) of the end members (Masunaka, annotated Fig 11 below) of Masunaka which will result in the second notches (Leeds, annotated 3 above) being aligned with a corresponding first notch (Hanlon, annotated 6 above) in order to make the shelves (Masunaka, annotated Fig 11 above) more aesthetically appealing. Further, the substitution of one known shelf bottom rail shape for another would have yielded predictable results to one of ordinary skill in the art at the time of the invention. Such a modification would have involved a mere change in the shape of a component. A change in shape is generally recognized as being within the level of ordinary skill in the art. PNG media_image12.png 855 1165 media_image12.png Greyscale Claim 31 is rejected under 35 U.S.C. 103 as being unpatentable over the combination of Masunaka 6,257,426 and Hanlon 2022/0287457; and further in view of Horn 2012/0031863. Regarding claim 31, modified Masunaka discloses the collapsible rack assembly (Fig 11) further comprising a third elongated shelf (annotated Fig 11 below) of the plurality of elongated shelves, the third elongated shelf (annotated Fig 11 below) comprising a plurality of feet (annotated Fig 11 below) (bottom portion of each post) disposed in the corner regions and said first connector (annotated Fig 11 below) thereof configured to receive and support a first end (top end) of said first vertical support (annotated Fig 11 below) and said second connector (annotated Fig 11 below) thereof configured to receive and support a first end (top end) of said second vertical support (annotated Fig 11 below).
