191

Days of term adjustment

Read from the USPTO patent term adjustment record, not recalculated here.

Unresolved

Terminal disclaimer

On file, reference document not resolved, so the date above is an upper bound. We do not guess the cap.

2 of 2

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.

Step	Input	Date after this step	Confidence
Base term, 20 years from filing	Clock starts Dec 22, 2000, when the earliest non-provisional application in its chain was filed (this one was filed Jul 28, 2006); a parent in its chain could not be resolved (the next row)	Dec 22, 2020	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	+191 days, USPTO patent term adjustment record	Jul 1, 2021	High confidence
Terminal disclaimer cap	Disclaimer on file (approved), reference document not resolved	no cap applied, and none guessed	Medium confidence
Patent term extension	None on file	no change	High confidence

USPTO status record	Recorded as expired for non-payment on Feb 14, 2022, after the term ended	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

This computed term ends no later than the date shown; an unresolved terminal disclaimer may end it earlier. Related patents and pending applications may cover overlapping subject matter.
