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 6, 2010, when application 12/961,436, the earliest non-provisional in its chain, was filed (this one was filed Dec 21, 2017); a parent in its chain could not be resolved (the next row) | Dec 6, 2030 | 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 |
