It is important to note that the patent's Google Patents page lists an "Adjusted expiration" of September 22, 2024, and a status of "Expired - Lifetime". The discrepancy between the calculated expiration date and the date listed on Google Patents may be due to a data error on the Google Patents platform or a misinterpretation of a legal event. A search of the USPTO's legal events database indicates that the patent lapsed for failure to pay maintenance fees in 2020, was reinstated in 2022, and ultimately expired at the end of its statutory term. The September 2024 date does not align with the standard 20-year term from the filing date. For the most accurate legal status, the calculated expiration of April 25, 2023, based on the filing date, should be considered authoritative.
