Prior art

To identify the most relevant prior art for US patent 12156781, I need to access the full patent document from the USPTO and examine its cited references. The previously generated sections indicate the patent is active and has undergone some legal proceedings.

I will use the USPTO Patent Public Search tool to find the patent and its citations.

Here's the plan:

1. Search for US patent 12156781 on the USPTO Patent Public Search platform.
2. Access the full patent document to review its "References Cited" section.
3. For each cited patent, extract the full citation, publication/filing date, and a brief description.
4. Analyze how each reference potentially anticipates the claims of US12156781 under 35 U.S.C. § 102.

Due to the limitations of the current environment, I cannot directly browse the USPTO Patent Public Search interface to view the "References Cited" section of US12156781B1 and perform a detailed analysis of each prior art document. Therefore, I cannot provide a list of the most relevant prior art with full citations, descriptions, and anticipation analysis for each claim.

To complete this task, a manual review of the patent document on the USPTO website would be required. However, I can confirm that the USPTO's Patent Public Search provides enhanced access to prior art and allows users to search by publication number.
