base term after the term ends fee events Updated Nov 14, 2026 · includes USPTO assignment & status data published Nov 14, 2026 and grant & fee data published Nov 10, 2026 (weekly) · how we know

None

Term adjustment

No prosecution delay on this record.

No effect

Terminal disclaimer

Resolved from the filed document, referencing US 8,301,108, to Oct 24, 2022. The term already ends on or before that date, so the cap shortened nothing.

2 of 2

Maintenance fees paid

Two maintenance fees can end this term early, the ones due 3.5 and 7.5 years from grant; the third one's grace period runs past the term end. This counts the ones the record shows paid.

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 Oct 24, 2002, when the earliest non-provisional application in its chain was filed (this one was filed Oct 29, 2012)	Oct 24, 2022	High confidence
Continuity chain	Every parent in the chain resolved	no change	High confidence
Patent term adjustment	None on file	no change	High confidence
Terminal disclaimer cap	Disclaimer resolved from the filed document (refs US 8,301,108)	resolves to Oct 24, 2022, no earlier than this term, so no change	High confidence
Patent term extension	None on file	no change	High confidence
Fee events	2 of 2 maintenance fees paid	term ended	High confidence
Computed term end	The steps above, in order	Oct 24, 2022	High confidence

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
