How we calculated this date
| Step | Input | Date after this step | Confidence |
|---|---|---|---|
| Base term, 20 years from filing | Clock starts Nov 6, 2012, when application 13/669,445, the earliest non-provisional in its chain, was filed (this one was filed Mar 9, 2016) | Nov 6, 2032 | 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 | Disclaimer on file (approved), reference document not resolved | no cap applied, and none guessed | Medium confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 3 of 3 maintenance fees paid | In force | High confidence |
| Computed term end | The steps above, in order | no later than Nov 6, 2032 | Low confidence |

A terminal disclaimer is on file (approved) and its reference document is not resolved. A disclaimer would cap the term earlier than Nov 6, 2032. We will not guess the cap.
