Regarding claim 10, Podemski discloses a structural assembly configured to accept a bolt (226, see Fig. 14), but does not disclose it is further comprising a rectangular nut member configured to accept a bolt inserted through the at least one opening. It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to utilize a nut on the bolt to prevent the bolt from becoming loose. It would also have been obvious utilize a rectangular nut depending on material availability, since there is no invention in merely changing the shape or form of an article without changing its function except in a design patent. Eskimo Pie Corp. v. Levous et al., 3 USPQ 23. Regarding claim 11, Podemski discloses a structural assembly wherein the corner connector is comprised of a first material, the first side rail and second side rail are comprised of a second [material] (col. 11, line 67-col. 12, line 2), but does not specifically disclose the lockbolts are comprised of a third [material]. It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention that the lockbolts may be comprised of a third, different material such as titanium depending on material availability, and since it has been held to be within the general skill of a worker in the art to select a known material on the basis of its suitability for the intended use as a matter of obvious design choice. In re Leshin, 125 USPQ 416. Claim(s) 9 is/are rejected under 35 U.S.C. 103 as being unpatentable over Podemski et al., U.S. Patent 9,549,482 in view of Neri, U.S. Patent 4,691,970. Regarding claim 9, Podemski discloses a structural assembly but does not disclose wherein the lockbolts are configured to compress the first and second side rail about the first and second prong, respectively. Neri teaches a similar assembly having pronged corner connectors (4) for joining hollow rail members (27), fasteners to be inserted through the outer surfaces of the rail members and into the prongs (at 24, 25). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to utilize a lockbolt in a similar manner and protruding through the prong and rail surfaces to further secure the assembly. Upon tightening, the rail would compress about the prong. The phrase “configured to compress the first and second side rail about the first and second prong, respectively” is a statement of intended use of the claimed invention and must result in a structural difference between the claimed invention and the prior art in order to patentably distinguish the claimed invention from the prior art. If the prior art structure is capable of performing the intended use, then it meets the claim.
