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, 20 years from filing	Clock starts Dec 6, 2005, when the earliest non-provisional application in its chain was filed (this one was filed Jun 25, 2018); a parent in its chain could not be resolved (the next row)	Dec 6, 2025	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	+395 days, the original patent's USPTO patent term adjustment record, which governs a reissue (35 U.S.C. 251). This reissue's own record carries none	Jan 5, 2027	Medium confidence
Terminal disclaimer cap	Disclaimer resolved from the filed document (refs US 7,179,561)	capped to Dec 6, 2025	High confidence
Patent term extension	None on file	no change	High confidence
Fee events	No fee event states this; the fee state is read from the payments the fee record holds	term ended	Medium confidence
Computed term end	The steps above, in order	Dec 6, 2025	Low confidence

Maintenance fee events come from USPTO's own fee records. Its fee lookup asks for the patent number and the application number.

Every date shows its work: the base term, any term adjustment or extension, any disclaimer cap, and the maintenance fee record, each with a confidence tier. How this record was built
