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 Oct 29, 2018, when application 16/173,970, the earliest non-provisional in its chain, was filed (this one was filed Jun 28, 2022); a parent in its chain could not be resolved (the next row) | Oct 29, 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 | +546 days, USPTO patent term adjustment record | Apr 27, 2040 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 10,344,091, US 10,450,374, US 11,629,191) | capped to Oct 29, 2038 | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 0 of 3 maintenance fees paid | In force | High confidence |
