Dates on the curated countdown pages are USPTO-adjusted expiration dates (verified against USPTO/Google Patents legal-status data as of July 2026, including patent-term adjustment); they still assume maintenance fees keep being paid, and are not a legal determination. Dates in the searchable database are raw patent-term math (20 years from filing, or the older 17-from-grant rule) that ignores adjustments, extensions, and terminal disclaimers. This is not legal advice.
