None

Term adjustment

Terminal disclaimer

Resolved from the filed document, referencing US 8,640,183, to May 8, 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.

Step	Input	Date after this step	Confidence
Base term, 20 years from filing	Clock starts May 8, 2003, when the earliest non-provisional application in its chain was filed (this one was filed Jan 6, 2014)	May 8, 2023	High confidence
Continuity chain	Every parent in the chain resolved	no change	High confidence
Patent term adjustment	None on file	no change	High confidence
Terminal disclaimer cap	Disclaimer resolved from the filed document (refs US 8,640,183)	resolves to May 8, 2023, no earlier than this term, so no change	High confidence
Patent term extension	None on file	no change	High confidence
Fee events	0 of 2 maintenance fees paid	lapsed Dec 16, 2018	High confidence
Computed term end	The steps above, in order	Dec 16, 2018	High confidence
