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 | +137 days, USPTO patent term adjustment record | Oct 14, 2028 | 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 | 1 of 1 maintenance fees paid | In force | High confidence |
| Computed term end | The steps above, in order | Oct 14, 2028 | Medium confidence |
