How we calculated this date
| Step | Input | Date after this step | Confidence |
|---|---|---|---|
| Base term, 20 years from filing | Clock starts Jul 3, 2009, when the earliest non-provisional application in its chain was filed (this one was filed Feb 9, 2011) | Jul 3, 2029 | High confidence |
| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | +315 days, USPTO patent term adjustment record | May 14, 2030 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 8,254,531) | capped to Aug 27, 2029 | Medium 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 RE46,653 and US RE47,279 and US RE48,933 issued Dec 26, 2017, and this patent's term continues in it (35 U.S.C. 251, 252) | surrendered Dec 26, 2017 | High confidence |
