Prior art

To identify the most relevant prior art for US patent 12008509, I will search the USPTO database for the specific patent number and then examine its cited references.

The USPTO provides a Patent Public Search tool for this purpose.

Upon searching the USPTO database for patent number 12008509, the most relevant prior art documents would be the "References Cited" section of the patent itself. These are the documents that the patent examiner and the applicant considered during the prosecution of the patent to establish its novelty and non-obviousness.

Since I cannot directly access a live, interactive USPTO database to pull the "References Cited" list in real-time, I will rely on the information provided in the Google Patents link you initially supplied for US12008509B2, which typically lists these citations.

For each reference, I will provide: full citation, publication/filing date, brief description, and which claim(s) it potentially anticipates under 35 U.S.C. § 102.

Based on the provided patent text, the "Prior art keywords" section mentions: "product", "computer", "delivery", "food", "food product". However, this is a general keyword list, not a list of specific prior art documents. The "Related Applications" section lists prior applications that US12008509B2 claims priority from, which are not prior art in the sense of 35 U.S.C. § 102, but rather part of the patent family.

Therefore, I need to search for the specific "References Cited" in US Patent 12008509. Since I cannot perform a live, interactive search of the USPTO database from this environment that would directly list the "References Cited" section of the patent, I must state that I do not have the requisite information to complete this specific part of the request.

If you can provide the "References Cited" section directly from US Patent 12008509, I can then proceed to analyze each reference for its potential anticipation of the claims under 35 U.S.C. § 102.
