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 |
|---|---|---|---|
| Base term, 20 years from filing | Clock starts Nov 1, 2005, when application 11/264,958, the earliest non-provisional in its chain, was filed (this one was filed Feb 21, 2020); a parent in its chain could not be resolved (the next row) | Nov 1, 2025 | High confidence |
| Continuity chain | A parent in the chain could not be resolved | dated from this application's own claim | Medium confidence |
| Patent term adjustment | +355 days, USPTO patent term adjustment record | Oct 22, 2026 | 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 maintenance fee can end the term early | term ended | High confidence |
| Computed term end | The steps above, in order | Oct 22, 2026 | Medium confidence |
