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 Aug 29, 2003, when the earliest non-provisional application in its chain was filed (this one was filed May 21, 2007)	Aug 29, 2023	High confidence
Continuity chain	Every parent in the chain resolved	no change	High confidence
Patent term adjustment	+1060 days, USPTO patent term adjustment record	Jul 24, 2026	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	No fee event states this; the fee state is read from the payments the fee record holds; the fee record shows no payment for this window, and USPTO's status still reads "Patented Case"	lapsed Jun 24, 2026	Low confidence
Computed term end	The steps above, in order	Jun 24, 2026	Low confidence

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

Not on this page: the patent's family, its recorded assignments and its citation count. USPTO's assignment records, linked above, list every recorded assignment.

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
