Term ended Apr 13, 2026 · Medium confidence

Computed 20-year base term

Why Medium: The disclaimer's references carry disclaimers of their own not yet read (US 10,572,898, US 8,356,253, US 9,361,632, US 9,805,393), so the cap could be lower.

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 10,068,253, US 10,565,618, US 10,572,898, US 11,488,206, US 11,587,117, US 7,870,497, US 8,356,253, US 8,930,832, US 9,361,632, US 9,805,393, to Apr 13, 2026. 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.

Base term, 20 years from filing	Clock starts Apr 13, 2006, when the earliest non-provisional application in its chain was filed (this one was filed Oct 31, 2022)	Apr 13, 2026	High confidence
Continuity chain	Every parent in the chain resolved	no change	High confidence

USPTO account required: This application in Patent Center · USPTO's maintenance fee lookup

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

Computed patent terms end on the dates shown. Related patents and pending applications may cover overlapping subject matter.
