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 29, 2013, when application 13/853,387, the earliest non-provisional in its chain, was filed (this one was filed Sep 17, 2024); a parent in its chain could not be resolved (the next row) | Mar 29, 2033 | 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 | +78 days, USPTO patent term adjustment record | Jun 15, 2033 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 10,997,814, US 11,699,319, US 12,125,334) | capped to Mar 29, 2033 | 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: 18324232 | Low confidence overall | Low confidence |
