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 Jun 4, 2019, when application 16/431,167, the earliest non-provisional in its chain, was filed (this one was filed Apr 20, 2020); a parent in its chain could not be resolved (the next row) | Jun 4, 2039 | 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 | +890 days, USPTO patent term adjustment record | Nov 10, 2041 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 11,734,555, US 11,853,871) | capped to Jun 4, 2039 | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 0 of 3 maintenance fees paid | In force | High confidence |
