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 | +365 days, USPTO patent term adjustment record | Mar 14, 2034 | High confidence |
| Terminal disclaimer cap | None on record | no cap applied | High confidence |
