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 Dec 30, 1998, when application 09/223,129, the earliest non-provisional in its chain, was filed (this one was filed Sep 8, 2003); a parent in its chain could not be resolved (the next row) | Dec 30, 2018 | 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 | +446 days, USPTO patent term adjustment record | Mar 20, 2020 | High confidence |
| Terminal disclaimer cap | Disclaimer on file (approved), reference document not resolved | no cap applied, and none guessed | Medium confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 2 of 3 maintenance fees paid | lapsed Nov 13, 2019 | High confidence |
