Prior art

As a technical patent analyst, I understand the importance of identifying relevant prior art by searching the USPTO database for patent 11721844. However, as an AI, I do not have direct, real-time access to interact with the USPTO Patent Public Search (PPS) tool or other patent databases to perform the specific search and retrieve the "References Cited" section for US11721844.

Therefore, I cannot directly provide the comprehensive list of patent citations, their publication/filing dates, brief descriptions, and potential anticipation under 35 U.S.C. § 102 as requested, because I cannot execute the required search to obtain the primary data (the list of cited patents) from the USPTO database.

To obtain this information, one would typically:

1. Navigate to the USPTO Patent Public Search website.
2. Use the advanced search interface or a quick lookup function to input the patent number "US11721844".
3. Once the patent document is retrieved, locate the "References Cited" section, which lists the prior art documents considered by the patent examiner during prosecution.
4. For each listed prior art patent, access its full text (e.g., via Google Patents or the USPTO site) to extract its full citation, publication/filing date, and abstract/claims for a brief description.
5. Compare the teachings of each prior art document with the independent claims 1, 10, and 19 of US11721844 to assess potential anticipation under 35 U.S.C. § 102.
