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 Jul 15, 2011, when the earliest non-provisional application in its chain was filed (this one was filed May 20, 2014)	Jul 15, 2031	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 8,740,028)	resolves to Jul 15, 2031, 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 RE48,093 issued Jul 14, 2020, and this patent's term continues in it (35 U.S.C. 251, 252)	surrendered Jul 14, 2020	High confidence
Surrendered on reissue	The steps above, in order	Jul 14, 2020	Low confidence
