| 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 8,327,395, US 8,332,883, US 9,021,515, US 9,571,877) | resolves to Oct 2, 2028, no earlier than this term, so no change | Medium confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 1 of 2 maintenance fees paid | lapsed Feb 13, 2026 | High confidence |
