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.

| 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 10,873,589, US 11,558,405, US 12,058,154) | resolves to Aug 8, 2037, no earlier than this term, so no change | Medium confidence |
| Patent term extension | None on file | no change | High confidence |
