| Continuity chain | A parent in the chain could not be resolved | dated from this application's own claim | Medium confidence |

| Terminal disclaimer cap | None on record | no cap applied | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 2 of 3 maintenance fees paid | In force | High confidence |
