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 Feb 12, 2018, when application 15/894,783, the earliest non-provisional in its chain, was filed (this one was filed Apr 20, 2018); a parent in its chain could not be resolved (the next row) | Feb 12, 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 | +30 days, USPTO patent term adjustment record | Mar 14, 2038 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 10,613,550) | resolves to Mar 14, 2038, no earlier than this term, so no change | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 1 of 3 maintenance fees paid | In force | High confidence |
| Further caveats on record | The record names parents not resolved: 15894783 | Low confidence overall | Low confidence |
| Computed term end | The steps above, in order | Mar 14, 2038 | Low confidence |
