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 Dec 1, 2010, when application 12/958,115, the earliest non-provisional in its chain, was filed (this one was filed Mar 1, 2017) | Dec 1, 2030 | High confidence |
| Continuity chain | A reissue: its term follows the original patent's, with the original's term adjustment | follows the original patent | Medium confidence |
| Patent term adjustment | No term adjustment record on a grant after 2005, so none is added | no change | Medium confidence |
| Terminal disclaimer cap | None on record | no cap applied | High confidence |
| Patent term extension | +989 days, USPTO 35 U.S.C. 156 certificate | added to Dec 1, 2030: Aug 16, 2033 | High confidence |
| Fee events | 3 of 3 maintenance fees paid | In force | High confidence |
| Computed term end | The steps above, in order | Aug 16, 2033 | Low confidence |
