Obviousness

I cannot perform an obviousness analysis of US patent 9232403 under 35 U.S.C. § 103 as requested. The "Prior art" section provided in the patent text only lists "Prior art keywords" (service, network, agent, usage, user) and a "Prior art date" (2009-01-28). It does not provide specific prior art references (e.g., other patents, publications, or non-patent literature) that would be necessary to identify combinations and explain the motivation for combining them to render the claims obvious.

Without a list of specific prior art documents, I am unable to analyze and determine if any combinations of such references would make the claims of US9232403B2 obvious to a person having ordinary skill in the art.
