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 5, 2001, when application 10/010,018, the earliest non-provisional in its chain, was filed (this one was filed Nov 1, 2002); a parent in its chain could not be resolved (the next row) | Dec 5, 2021 | 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 | +912 days, USPTO patent term adjustment record | Jun 4, 2024 | High confidence |
| Terminal disclaimer cap | None on record | no cap applied | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 3 of 3 maintenance fees paid | term ended | High confidence |
| Computed term end | The steps above, in order | Jun 4, 2024 | Medium confidence |
