Regarding claim 24, Revuelta further discloses the first side rail assembly being formed of multiple sections (68), releasably joined together (via base 10 which contain hollow tubes 32 in which 68 rests. Revuelta, Figure 3. Revuelta translation: “ Each railing 68 comprises on the one hand two uprights whose lower ends are capable of fitting into the hollow tubes 32”). Regarding claim 25, Revuelta further discloses the second side rail assembly being formed of multiple sections (68) releasably joined together (via base 10 which contain hollow tubes 32 in which 68 rests. Revuelta, Figure 3. Revuelta translation: “ Each railing 68 comprises on the one hand two uprights whose lower ends are capable of fitting into the hollow tubes 32”). Regarding claim 26, Revuelta further discloses the first and second side rail assemblies including respective top rails, center rails, and bottom rails (Revuelta, Figure 9). Regarding claim 27, Revuelta further discloses the second side rail, the first support post, and the second support post each including respective latch posts (Revuelta translation: “ According to one embodiment, each gate 72 includes at the level of a post two hinges 74, each having an axis oriented downwards, cooperating with two sleeves (or two tabs each with an opening) attached to a post of a railing 68 so as to form two hinges.”). Regarding claim 29, Revuelta further discloses the first side rail assembly being formed of multiple sections (68) releasably joined together (via base 10 which contain hollow tubes 32 in which 68 rests.

Regarding claim 30, Revuelta further discloses the first and second side rail assemblies include respective top rails, center rails, and bottom rails (Revuelta, Figure 9). Regarding claim 31, Revuelta discloses a guard rail system for a scaffold; the scaffold having first, second, third, and fourth guard rail mounting points (at 24) located proximate corresponding corners of the scaffold (Revuelta, Figure 2); the guard rail system comprising: a first side rail assembly (formed by 68) configured to mount to the first and second mounting points; the first side rail assembly having longitudinally opposing first and second end portions (Revuelta, Figure 9); a second side rail assembly (formed by 68) configured to mount to the third and fourth mounting points (Revuelta, Figure 9); a first gate (72) configured to be pivotally mounted to the first end portion of the first side rail assembly (via 74); a second gate (72) configured to be pivotally mounted to the second end portion of the first side rail assembly (via 74); a first support post (32) configured to mount to the third mounting point; a second support post (32) configured to mount to the fourth mounting point; wherein the guard rail system is changeable between a four-sided configuration (Revuelta, Figures 9) and an three-sided configuration (in that isolated upright posts can be used. Revuelta translation: “Each gate 72 includes at the level of the other upright at least one hinge 76, having an axis oriented downwards and cooperating with at least one sleeve (or at least one tab with an opening) attached to an isolated upright 70 or to an upright of a railing 68 so as to form a latch.”); wherein in the four-sided configuration, the guard rail system forms a closed perimeter fence (Revuelta, Figure 9) and: the first gate is pivotally mounted to the first end portion of the first side rail assembly and extends to and is latched (at 76) to the second side rail assembly (Revuelta translation: “ According to one embodiment, each gate 72 includes at the level of a post two hinges 74, each having an axis oriented downwards, cooperating with two sleeves (or two tabs each with an opening) attached to a post of a railing 68 so as to form two hinges.”); and the second gate is pivotally mounted to the second end portion of the first side rail assembly and extends to and is latched to (at 76) the second side rail assembly (Revuelta translation: “ According to one embodiment, each gate 72 includes at the level of a post two hinges 74, each having an axis oriented downwards, cooperating with two sleeves (or two tabs each with an opening) attached to a post of a railing 68 so as to form two hinges.”); and; wherein, in the three-sided configuration, the guard rail system forms a perimeter fence open on one side and: the first gate is pivotally mounted to the first side rail assembly and extends to and is latched to the first support post with the second gate is pivotally mounted to the first side rail assembly, and extends to and is latched to, the second support post (Revuelta translation: “ According to one embodiment, each gate 72 includes at the level of a post two hinges 74, each having an axis oriented downwards, cooperating with two sleeves (or two tabs each with an opening) attached to a post of a railing 68 so as to form two hinges.”); and the second side rail assembly is detached from all of the first side rail assembly, the first gate, and the second gate (in that the scaffold is modular). Regarding claim 32, Revuelta further discloses the first side rail assembly including a first hinge portion in the first end portion and another first hinge portion in the second end portion; wherein the first gate includes a second hinge portion configured to mate with the first hinge portion in the first end portion to pivotally mount the first gate to the first side rail; wherein the second gate includes a second hinge portion configured to mate with the first hinge portion in the second end portion to pivotally mount the second gate to the first side rail (Revuelta translation: “ According to one embodiment, each gate 72 includes at the level of a post two hinges 74, each having an axis oriented downwards, cooperating with two sleeves (or two tabs each with an opening) attached to a post of a railing 68 so as to form two hinges.”).

Regarding claim 40, Revuelta further discloses the first and second side rail assemblies including respective top rails, center rails, and bottom rails (Revuelta, Figure 9). 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(s) 28 and 38 is/are rejected under 35 U.S.C. 103 as being unpatentable over Revuelta FR 2941729 in view of Ruemmer DE 102010009247. Regarding claims 28 and 38, Revuelta discloses the guard rail system of claims 27 and 37, respectively. Revuelta fails to disclose the latch posts each including a locking member rotatable about a pivot pin. Ruemmer teaches a guard rail system having latch posts (21p) including a locking member (32) rotatable about a pivot pin (321). It would have been obvious to one of ordinary skill in the art before the filing date of the invention with a reasonable expectation of success to modify each latch post of Revuelta with a locking member rotatable about a pivot pin as taught by Ruemmer as to provide a way to secure the guard rails to the posts. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure: US 2023/0235580; KR 2006033757.
