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 Feb 13, 2009, when application 12/371,429, the earliest non-provisional in its chain, was filed (this one was filed Mar 11, 2013); a parent in its chain could not be resolved (the next row) | Feb 13, 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 | +215 days, USPTO patent term adjustment record | Sep 16, 2029 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 8,237,563) | resolves to Sep 16, 2029, no earlier than this term, so no change | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 3 of 3 maintenance fees paid | In force | High confidence |
| Computed term end | The steps above, in order | Sep 16, 2029 | Medium confidence |
