Days of term adjustment

No effect

Terminal disclaimer

Resolved from the filed document, referencing US 7,674,184, to Dec 21, 2023. The term already ends on or before that date, so the cap shortened nothing.

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.

USPTO status record	Recorded as expired for non-payment on Aug 26, 2024, after the term ended	no change	High 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
