| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | None on file | no change | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 7,884,075) | resolves to Mar 29, 2027, no earlier than this term, so no change | Medium confidence |
