Obviousness

The provided patent text for US8103865, specifically the "Prior art keywords" section, lists general terms such such as "wireless device," "rendering," "page description," "server," and "custom configuration". However, it does not identify or list any specific prior art patents, publications, or other references that would be necessary to conduct an obviousness analysis under 35 U.S.C. § 103.

To perform an obviousness analysis, one would typically combine specific teachings from two or more identified prior art references to demonstrate that the claimed invention would have been obvious to a person having ordinary skill in the art (PHOSITA). Without specific prior art references from the "Prior Art" section of the provided patent document, it is not possible to:

1. Identify combinations of prior art references.
2. Explain why a PHOSITA would have been motivated to combine them.

The "RELATED U.S. PATENT APPLICATION" mentioned in the patent's description, U.S. patent application Ser. No. 11/888,803, shares the same filing date and inventors, making it a related application rather than a prior art reference for an obviousness analysis under 35 U.S.C. § 103.

Therefore, based strictly on the information provided in the patent text and its "Prior art" section, I cannot identify specific combinations of prior art references or elaborate on the motivation for combining them to render the claims of US8103865 obvious.
