base term after the term ends Updated Nov 15, 2026 · includes USPTO assignment & status data published Nov 15, 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 10,102,184, US 9,405,735, US 9,892,093, to Jul 16, 2021. The term already ends on or before that date, so the cap shortened nothing.

None due

Maintenance fees

This term ends before the first maintenance fee's grace period does, 4 years from grant, so no fee can end it early.

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.

Fee events	No maintenance fee can end the term early	term ended	High confidence
USPTO status record	Recorded as expired for non-payment on Nov 25, 2024, after the term ended	no change	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
