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 Oct 18, 2007, when application 11/874,690, the earliest non-provisional in its chain, was filed (this one was filed Dec 7, 2012); a parent in its chain could not be resolved (the next row) | Oct 18, 2027 | 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 | None on file | no change | 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 fee event states this; the fee state is read from the payments the fee record holds; the fee record shows no payment for this window, and USPTO's status still reads "Patented Case" | lapsed Oct 23, 2026 | Low confidence |
| Computed term end | The steps above, in order | Oct 23, 2026 | Low confidence |
