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 Oct 27, 2009, when application 12/607,009, the earliest non-provisional in its chain, was filed (this one was filed Nov 30, 2020); a parent in its chain could not be resolved (the next row) | Oct 27, 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 | +218 days, USPTO patent term adjustment record | Jun 2, 2030 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 9,409,021, US 9,744,360) | capped to Oct 27, 2029 | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 0 of 1 maintenance fees paid | In force | High confidence |
| Further caveats on record | The record names parents not resolved: 16167958 | Low confidence overall | Low confidence |
