How we calculated this date

One row per rule, each showing its own input and what it did to the date. A step we could not verify says so instead of resolving itself.

Step	Input	Date after this step	Confidence
Base term, the 1995 transition rule	Granted Nov 8, 2005 + 17 years, or clock starts Apr 13, 1992 + 20 years, whichever is later; a parent in its chain could not be resolved (the next row)	Nov 8, 2022	High confidence
Continuity chain	A reissue: its term follows the original patent's, with the original's term adjustment; a parent in the chain could not be resolved	dated from this application's own claim	Low confidence
Patent term adjustment	None on file	no change	High confidence
Terminal disclaimer cap	None on record	no cap applied	High confidence
Patent term extension	None on file	no change	High confidence
Fee events	The reissue's fees post to its original, whose fee record is not available (likely before 2001)	term ended	Medium confidence
Computed term end	The steps above, in order	Nov 8, 2022	From the USPTO record
