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 Mar 24, 2005, when application 11/089,081, the earliest non-provisional in its chain, was filed (this one was filed Oct 16, 2012); a parent in its chain could not be resolved (the next row) | Mar 24, 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 | +213 days, USPTO patent term adjustment record | Oct 23, 2025 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 8,331,723) | resolves to Oct 23, 2025, no earlier than this term, so no change | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 2 of 2 maintenance fees paid | term ended | High confidence |
| Further caveats on record | The record names parents not resolved: 12274032, 11089081, 12274032, 11089081 | Low confidence overall | Low confidence |
| Computed term end | The steps above, in order | Oct 23, 2025 | Low confidence |
