base term after the term ends 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 11,368,660, to Mar 10, 2037. The term already ends on or before that date, so the cap shortened nothing.

0 of 3

Maintenance fees paid

Three maintenance fees fall due, at 3.5, 7.5 and 11.5 years from grant. 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 Mar 10, 2017, when the earliest non-provisional application in its chain was filed (this one was filed Nov 9, 2020); a parent in its chain could not be resolved (the next row)	Mar 10, 2037	High confidence
Continuity chain	A parent in the chain could not be resolved	dated from this application's own claim	Medium confidence
Patent term adjustment	None on file	no change	High confidence
Terminal disclaimer cap	Disclaimer resolved from the filed document (refs US 11,368,660)	resolves to Mar 10, 2037, no earlier than this term, so no change	High confidence
Patent term extension	None on file	no change	High confidence
Fee events	0 of 3 maintenance fees paid	lapsed Jun 21, 2026	High confidence
Computed term end	The steps above, in order	Jun 21, 2026	Medium 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
