One row per rule, each showing its own input and what it did to the date. A step we could not verify says so instead of resolving itself.

| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | +220 days, USPTO patent term adjustment record | Oct 3, 2025 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 7,508,922) | resolves to Oct 3, 2025, no earlier than this term, so no change | High confidence |
| Patent term extension | None on file | no change | High confidence |
