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 Mar 10, 2011, when application 13/044,548, the earliest non-provisional in its chain, was filed (this one was filed Nov 2, 2018); a parent in its chain could not be resolved (the next row) | Mar 10, 2031 | High confidence |
| Continuity chain | A parent in the chain could not be resolved | dated from this application's own claim | Medium confidence |

| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 9,666,294) | capped to Mar 10, 2031 | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 1 of 2 maintenance fees paid | In force | High confidence |
