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 Sep 30, 2014, when application 14/503,021, the earliest non-provisional in its chain, was filed (this one was filed Feb 20, 2020); a parent in its chain could not be resolved (the next row) | Sep 30, 2034 | 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 | +185 days, USPTO patent term adjustment record | Apr 3, 2035 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 10,588,843, US 10,987,294, US 9,187,538, US 9,511,012, US 9,517,191, US 9,522,107) | capped to Sep 30, 2034 | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 1 of 3 maintenance fees paid | In force | High confidence |
