| Continuity chain | A parent in the chain could not be resolved | dated from this application's own claim | Medium confidence |
| Patent term adjustment | +31 days, USPTO patent term adjustment record | Mar 26, 2040 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 11,765,463, US 12,069,375) | capped to Feb 24, 2040 | High confidence |
| Patent term extension | None on file | no change | High confidence |
