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 10, 2006, when application 11/484,370, the earliest non-provisional in its chain, was filed (this one was filed Feb 15, 2011) | Jul 10, 2026 | 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 7,890,891, US 7,910,993, US 8,129,787, US 8,405,147) | resolves to Jul 10, 2026, 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 RE48,965 issued Mar 8, 2022, and this patent's term continues in it (35 U.S.C. 251, 252) | surrendered Mar 8, 2022 | High confidence |
