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 Nov 2, 2006, when application 11/591,768, the earliest non-provisional in its chain, was filed (this one was filed Apr 11, 2014); a parent in its chain could not be resolved (the next row) | Nov 2, 2026 | 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 | 2 of 2 maintenance fees paid | term ended | High confidence |
| Computed term end | The steps above, in order | Nov 2, 2026 | Medium confidence |
