How we calculated this date
| Step | Input | Date after this step | Confidence |
|---|---|---|---|
| Base term, 20 years from filing | Clock starts Nov 22, 2006, when application 11/562,625, the earliest non-provisional in its chain, was filed (this one was filed Mar 19, 2013); a parent in its chain could not be resolved (the next row) | Nov 22, 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 | Disclaimer on file (approved), reference document not resolved | no cap applied, and none guessed | Medium confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 2 of 2 maintenance fees paid | In force | High confidence |
| Computed term end | The steps above, in order | no later than Nov 22, 2026 | Low confidence |

Maintenance fee events come from USPTO's own fee records. Its fee lookup asks for the patent number and the application number.
What's changing
A terminal disclaimer is on file (approved) and its reference document is not resolved. A disclaimer would cap the term earlier than Nov 22, 2026. We will not guess the cap.
