| Continuity chain | Every parent in the chain resolved | no change | High confidence |

| Terminal disclaimer cap | None on record | no cap applied | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | No fee event states this; the fee state is read from the payments the fee record holds | no change | Medium confidence |
