| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | +68 days, USPTO patent term adjustment record | Oct 1, 2026 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 7,880,154) | resolves to Oct 1, 2026, no earlier than this term, so no change | Medium confidence |
