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 Mar 8, 2009, when application 12/399,960, the earliest non-provisional in its chain, was filed (this one was filed Apr 10, 2017); a parent in its chain could not be resolved (the next row) | Mar 8, 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 | None on file | no change | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 10,479,892, US 9,617,424, US 9,884,965, US 9,896,582) | resolves to Mar 8, 2029, no earlier than this term, so no change | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 2 of 2 maintenance fees paid | In force | High confidence |
| Further caveats on record | The record names parents not resolved: 14304961, 13311445, 12399960 | Low confidence overall | Low confidence |
| Computed term end | The steps above, in order | Mar 8, 2029 | Low confidence |
