Prior art

The search results did not directly provide the claims of US11277650 or the publication/filing dates for the Japanese prior art documents. The first search result is completely irrelevant to US11277650, seemingly a mistake in the search query interpretation or results. Other search results are also not related to the specific patent US11277650 or the Japanese prior art mentioned.

Since I am instructed to use the provided full patent text as authoritative, and the claims are not present there, I will need to perform a search that is more likely to yield the complete patent document including claims. I will use the Google Patents link provided in the initial prompt to access the full patent text, and then extract the claims from there, assuming it includes them. I will then perform separate searches for the publication dates of the Japanese prior art.

Let's try a direct search for the Japanese patent numbers to get their publication dates. I will also assume the Google Patents link for US11277650 has the full patent text including claims.

Revised Plan:

1. Access US11277650 on Google Patents using the provided URL: https://patents.google.com/patent/US11277650/en to get the claims.
2. Search for publication dates of "JP-A-2002-169747" and "JP-A-2005-198061".
3. Extract relevant information for the prior art.
4. Analyze Claim 1 of US11277650 against the description of the prior art provided in the patent itself to determine potential anticipation under 35 U.S.C. § 102.

Since I cannot browse external websites like patents.google.com directly but was given the content of US11277650 (which I previously noted did not contain the claims), I must specifically ask for a search that provides the claims. My earlier attempt to get claims did not work.

The prompt states: "Search the USPTO database for the specific patent number 11277650. Do not return results for similar numbers."
Since I cannot directly interface with the USPTO database, and my initial Google Search for "US11277650 claims" did not return the claims, I will try a more direct search for the patent on Google Patents, as the initial authoritative text was fetched from there. I will then need to assume I can extract the claims from that Google Patents page.

Given the constraints, I will proceed with the information I have from the provided patent text about the Japanese prior art (JP-A-2002-169747 and JP-A-2005-198061) and will perform a targeted search for their publication dates. I will also clearly state that the claims text for US112777650 was not present in the provided authoritative text, and thus I cannot perform a detailed claim-by-claim anticipation analysis. I will, however, use the description of what the patent states about the prior art to discuss its potential for anticipation on a general level.

Let's try to get the dates for the Japanese patents.
