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 Dec 11, 2006, when application 11/637,514, the earliest non-provisional in its chain, was filed (this one was filed Sep 19, 2014); a parent in its chain could not be resolved (the next row) | Dec 11, 2026 | High confidence |
| Continuity chain | A reissue: its term follows the original patent's, with the original's term adjustment; a parent in the chain could not be resolved | dated from this application's own claim | Low confidence |
| Patent term adjustment | No term adjustment record on a grant after 2005, so none is added | no change | Medium confidence |
| Terminal disclaimer cap | None on record | no cap applied | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | The reissue's fees post to its original, whose fee record is not available (likely before 2001) | In force | Medium confidence |
| Computed term end | The steps above, in order | Dec 11, 2026 | Low confidence |
