Obviousness

I cannot perform a comprehensive obviousness analysis under 35 U.S.C. § 103 for US patent 12089889, as the "Prior Art" section of this analysis explicitly states that specific prior art citations (patent numbers and their detailed descriptions) were not available.

The previous "Prior Art" section noted: "Since I do not have direct access to the USPTO database search results for "cited references" of US patent 12089889, I cannot provide a list of the most relevant prior art citations with their detailed descriptions and specific claim anticipations under 35 U.S.C. § 102. The provided patent text includes a section for "Prior art keywords" (end effector, electrodes, energy, tissue, nasal) and "Prior art date" (2020-04-09), but it does not list the specific patent citations themselves. To fulfill your request completely, I would need to perform a search within the USPTO database for the cited references of US12089889B2 and then analyze each one for its relevance and potential anticipation of claims. Without that specific list of cited patents from the USPTO, I cannot proceed with the requested level of detail."

Without concrete prior art references, their teachings, and the specific claims they disclose, it is not possible to:

1. Identify meaningful combinations of prior art references.
2. Articulate why a person having ordinary skill in the art (POSITA) would have been motivated to combine these non-existent references to arrive at the claimed invention of US12089889.

Therefore, I must explicitly state that I lack the requisite information to fulfill this task.
