Prior art

To identify the most relevant prior art for US patent 11520346, I would need to access a patent database that provides citation information. The USPTO's Patent Public Search tool would be ideal for this purpose. However, since I cannot directly interact with web interfaces or conduct live, interactive searches beyond the initial Google Search, I can only provide an overview of the process and how the information would typically be extracted.

Process to identify prior art and potential anticipation:

1. Access USPTO Patent Public Search: I would navigate to the USPTO Patent Public Search website.
2. Search for US11520346: I would input the patent number "11520346" into the search field, specifically using the patent number search function to ensure precise results.
3. Retrieve Citation List: Once the patent record for US11520346 is displayed, I would look for a section listing "Cited By" or "References Cited". This section typically includes both U.S. patents and foreign patent documents, as well as non-patent literature that the examiner considered as prior art during prosecution.
4. Extract Information for Each Reference: For each patent listed as prior art, I would then gather the following:
   • Full Citation: Patent number, inventor(s), issue date.
   • Publication/Filing Date: Both dates are important for 35 U.S.C. § 102 analysis.
   • Brief Description: I would review the abstract and potentially key figures or the specification to understand the core technology and claims of the cited patent.
   • Potential Anticipated Claim(s) under 35 U.S.C. § 102: This step requires a detailed comparison of the elements of US11520346's claims (especially the independent claims 1, 9, and 16) against the disclosure of each prior art reference. For a reference to anticipate a claim under § 102, it must disclose every single element of that claim, either explicitly or inherently.

Limitation in current response:

Without the ability to directly access and parse the detailed citation data from the USPTO database, I cannot provide the specific list of prior art, their descriptions, or a definitive analysis of which claims of US11520346 they potentially anticipate. The provided patent text only lists "Prior art keywords" but not specific patent citations. [cite: The full patent text confirms this information]

Therefore, I cannot fulfill the request to provide the most relevant prior art for US patent 11520346 with specific citations, descriptions, and anticipation analysis under 35 U.S.C. § 102 at this time.
