Dates here are estimates from patent-term math (20 years from filing, or the older 17-from-grant/20-from-filing rule for pre-1995 filings), not a legal determination. They ignore patent-term adjustments, extensions, and terminal disclaimers, and don't reflect maintenance-fee lapses that haven't happened yet. This is not legal advice.
