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 | +265 days, USPTO patent term adjustment record | Feb 10, 2030 | High confidence |

Assignments

What's changing
Note
A terminal disclaimer is on file and its reference is not resolved. No cap is applied and none is guessed

The 265 days of patent term adjustment (USPTO delay) are read from the USPTO record, not recalculated by us
Open question
A terminal disclaimer is on file (approved) and its reference document is not resolved. A disclaimer would cap the term earlier than Jul 23, 2025. We will not guess the cap.
