Obviousness

The provided text from the Google Patents page for US9147297B2 includes "Prior art keywords: user, vehicle, infotainment, data, sensors" and a "Prior art date: 2012-03-14." However, it does not include a direct list of specific "Prior art citations" or "References Cited" documents, which are typically found on a full Google Patents page and are necessary for a detailed obviousness analysis under 35 U.S.C. § 103 by combining references. The "Priority claimed from" documents are related applications from which US9147297 claims priority, not prior art against it.

To proceed with the obviousness analysis as requested, it is necessary to identify specific prior art references. Since the provided text is incomplete in this regard, a live web search for prior art citations for US9147297B2 is warranted to gather this information from the authoritative Google Patents source.

The search results clarify the nature of prior art and the process of citing it at the USPTO. However, they do not directly provide a list of "Prior art citations" for US9147297B2, which would contain specific patent or publication numbers. The information from the Google Patents page that was initially provided to me simply does not contain this specific list. Without a concrete list of prior art references (patents, publications, etc.) explicitly cited against US9147297, I cannot fulfill the request to "Identify combinations of prior art references that would render the claims obvious" and explain the motivation to combine those specific references.

Therefore, I must explicitly state that based on the provided text and the supplementary search, I cannot identify specific prior art references for US9147297B2. The request for an obviousness analysis, which depends on combining specific prior art, cannot be performed with the information currently available.
