None

Term adjustment

No prosecution delay on this record.

No effect

Terminal disclaimer

Resolved from the filed document, referencing US 7,819,275, US 8,313,004, US 8,931,660, to Jul 3, 2021. The term already ends on or before that date, so the cap shortened nothing.

Maintenance fees paid

One maintenance fee can end this term early, the one due 3.5 years from grant; the next one's grace period runs past the term end. This counts it if the record shows it 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 Jul 3, 2001, when the earliest non-provisional application in its chain was filed (this one was filed Jan 9, 2015); a parent in its chain could not be resolved (the next row)	Jul 3, 2021	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 7,819,275, US 8,313,004, US 8,931,660)	resolves to Jul 3, 2021, no earlier than this term, so no change	Medium confidence
Patent term extension	None on file	no change	High confidence
Fee events	1 of 1 maintenance fees paid	term ended	High confidence
USPTO status record	Recorded as expired for non-payment on Jul 29, 2024, after the term ended	no change	High confidence
