How we calculated this date
| Step | Input | Date after this step | Confidence |
|---|---|---|---|
| Base term, 20 years from filing | Clock starts May 22, 2009, when application 12/470,550, the earliest non-provisional in its chain, was filed (this one was filed Nov 22, 2011); a parent in its chain could not be resolved (the next row) | May 22, 2029 | 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 | +90 days, USPTO patent term adjustment record | Aug 20, 2029 | 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 | 3 of 3 maintenance fees paid | In force (reinstated) | High confidence |
| Computed term end | The steps above, in order | no later than Aug 20, 2029 | Low confidence |

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 Aug 20, 2029. We will not guess the cap.
