How we calculated this date
| Step | Input | Date after this step | Confidence |
|---|---|---|---|
| Base term, 20 years from filing | Clock starts Dec 27, 2006, when application 11/616,382, the earliest non-provisional in its chain, was filed (this one was filed Mar 10, 2017); a parent in its chain could not be resolved (the next row) | Dec 27, 2026 | High confidence |
| Continuity chain | A parent in the chain could not be resolved | dated from this application's own claim | Medium confidence |
| Patent term adjustment | None on file | no change | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 7,615,385, US 9,136,457, US 9,595,656) | resolves to Dec 27, 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" | lapsed Oct 23, 2026 | Low confidence |
| Computed term end | The steps above, in order | Oct 23, 2026 | Low confidence |
