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 30, 2018, when application 16/206,667, the earliest non-provisional in its chain, was filed (this one was filed Dec 8, 2021); a parent in its chain could not be resolved (the next row) | Nov 30, 2038 | 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 |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 10,574,302) | resolves to Nov 30, 2038, no earlier than this term, so no change | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 0 of 3 maintenance fees paid | In force | High confidence |
| Further caveats on record | The record names parents not resolved: 16748776 | Low confidence overall | Low confidence |
| Computed term end | The steps above, in order | Nov 30, 2038 | Low confidence |
