| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | +955 days, USPTO patent term adjustment record | Mar 12, 2029 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 8,532,930) | resolves to Mar 12, 2029, no earlier than this term, so no change | Medium confidence |
