| 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 8,015,368) | resolves to Apr 21, 2028, no earlier than this term, so no change | High confidence |
| Patent term extension | None on file | no change | High confidence |
