Term adjustment

No prosecution delay on this record.

Fees paid on this patent before its reissue. Those after fall due on the reissue, which carries the term on.

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 24, 2007, when the earliest non-provisional application in its chain was filed (this one was filed Jan 3, 2014)	Sep 24, 2027	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 8,648,867)	resolves to Sep 24, 2027, no earlier than this term, so no change	High confidence
Patent term extension	None on file	no change	High confidence
Fee events	No fee event states this; the fee state is read from the payments the fee record holds; the fee record shows no payment for this window, and USPTO's status still reads "Patented Case"	no change	Low confidence
Reissue	US RE48,438 and US RE49,461 issued Feb 16, 2021, and this patent's term continues in it (35 U.S.C. 251, 252)	surrendered Feb 16, 2021	High confidence
Surrendered on reissue	The steps above, in order	Feb 16, 2021	Low confidence
