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.
| Step | Input | Date after this step | Confidence |
|---|---|---|---|

| Continuity chain | A parent in the chain could not be resolved | dated from this application's own claim | Medium confidence |

| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 8,286,209, US 8,429,695) | resolves to Feb 16, 2029, no earlier than this term, so no change | High confidence |
| Patent term extension | None on file | no change | High confidence |
