How we calculated this date
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 | A parent in the chain could not be resolved | dated from this application's own claim | Medium confidence |
| Patent term adjustment | +812 days, USPTO patent term adjustment record | Dec 19, 2025 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 7,502,943, US 7,519,833, US 7,536,560) | capped to Oct 20, 2025 | High confidence |
| Patent term extension | None on file | no change | High confidence |
