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 Aug 25, 2004, when application 10/925,693, the earliest non-provisional in its chain, was filed (this one was filed Dec 10, 2009) | Aug 25, 2024 | High confidence |
| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | +142 days, USPTO patent term adjustment record | Jan 14, 2025 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 7,803,865) | resolves to Jan 14, 2025, no earlier than this term, so no change | Medium 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 | Jan 14, 2025 | Medium confidence |
