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

| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | +54 days, USPTO patent term adjustment record | Oct 29, 2034 | High confidence |
| Terminal disclaimer cap | None on record | no cap applied | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | No fee event states this; the fee state is read from the payments the fee record holds; the fee record shows no payment for this window, and USPTO's status still reads "Patented Case"; the grace period ended with no payment on record in the fee file | grace period ended Oct 30, 2026 | Low confidence |
