US 9,066,404 In force, term unresolved

Term ends no later than Feb 22, 2030 · Low confidence

Computed 20-year base term

In force on USPTO's status record and by its fee record. A terminal disclaimer on file may shorten this term, possibly to a date already past; its reference document is unresolved, so the date above is an upper bound and no earlier date is guessed.

606

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.

3 of 3

Maintenance fees paid

Three maintenance fees fall due, at 3.5, 7.5 and 11.5 years from grant. 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 Jun 26, 2008, when the earliest non-provisional application in its chain was filed (this one was filed Feb 19, 2011); a parent in its chain could not be resolved (the next row)	Jun 26, 2028	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	+606 days, USPTO patent term adjustment record	Feb 22, 2030	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
Fee events	3 of 3 maintenance fees paid	In force	High confidence
Computed term end	The steps above, in order	no later than Feb 22, 2030	Low 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.

In force means the term is running and no lapse is on record. It is not a finding that the patent is valid.
