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 Nov 13, 2017, when application 15/811,415, the earliest non-provisional in its chain, was filed (this one was filed May 29, 2020); a parent in its chain could not be resolved (the next row) | Nov 13, 2037 | High confidence |
| Continuity chain | A parent in the chain could not be resolved | dated from this application's own claim | Medium confidence |
