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.

|---|---|---|---|
| Base term, 20 years from filing | Clock starts Jul 26, 2005, when this application, 11/189,353, was filed | Jul 26, 2025 | High confidence |
| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | +450 days, USPTO patent term adjustment record | Oct 19, 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 | 3 of 3 maintenance fees paid | term ended | High confidence |
| Computed term end | The steps above, in order | Oct 19, 2026 | High confidence |
