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 Nov 6, 2008, when applications 12/266,101, 12/266,146, 12/266,226, 12/266,252 and 12/266,320, the earliest non-provisional applications in its chain, were filed (this one was filed Oct 9, 2020); a parent in its chain could not be resolved (the next row) | Nov 6, 2028 | High confidence |
| Continuity chain | A parent in the chain could not be resolved | dated from this application's own claim | Medium confidence |
