Obviousness

I am unable to perform an obviousness analysis of US patent 11209863 under 35 U.S.C. § 103, as the provided patent text does not include a list of specific prior art references (e.g., patents, publications) that would be required for such an analysis. The "Prior art keywords" and "Prior art date" listed in the patent metadata are insufficient to identify combinations of references and discuss motivations for combining them to render claims obvious.

To conduct an obviousness analysis, specific prior art documents, along with their disclosures, would need to be identified and examined in relation to the claims of US11209863.
