Obviousness

I cannot perform an obviousness analysis of US Patent 11,520,378 under 35 U.S.C. § 103 as requested.

The provided patent text includes a section labeled "Prior art keywords" with terms such as "structural support," "support segment," "segment," "segments," and "state." However, this section lists keywords used for searching prior art and does not provide specific prior art documents (e.g., patent numbers, publication numbers, or non-patent literature) that were considered during the patent's prosecution or are intended for this analysis.

To conduct an obviousness analysis, I require actual prior art references to evaluate the claims of US11520378B2 against. Without specific prior art documents, I cannot identify combinations of references or articulate motivations for combining them to render the claims obvious to a person having ordinary skill in the art.
