| Continuity chain | A parent in the chain could not be resolved | dated from this application's own claim | Medium confidence |
| Patent term adjustment | +28 days, USPTO patent term adjustment record | Dec 28, 2030 | High confidence |
| Terminal disclaimer cap | None on record | no cap applied | High confidence |
