Terminal disclaimer

Resolved from the filed document, referencing US 6,714,510, to Jun 28, 2019. 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 Sep 15, 1995, when the earliest non-provisional application in its chain was filed (this one was filed Nov 16, 2007); a parent in its chain could not be resolved (the next row)	Sep 15, 2015	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	+1382 days, USPTO patent term adjustment record	Jun 28, 2019	High confidence
Terminal disclaimer cap	Disclaimer resolved from the filed document (refs US 6,714,510)	resolves to Jun 28, 2019, no earlier than this term, so no change	High confidence
Patent term extension	None on file	no change	High confidence
Fee events	0 of 1 maintenance fees paid	lapsed Dec 24, 2017	High confidence
Computed term end	The steps above, in order	Dec 24, 2017	Medium 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

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