How we calculated this date
| Step | Input | Date after this step | Confidence |
|---|---|---|---|
| Base term, 20 years from filing | Clock starts Jan 7, 2002, when the earliest non-provisional application in its chain was filed (this one was filed Dec 3, 2004) | Jan 7, 2022 | High confidence |
| Continuity chain | A reissue: its term follows the original patent's, with the original's term adjustment | follows the original patent | Medium confidence |
| Patent term adjustment | No term adjustment record on a grant after 2005, so none is added | no change | Medium 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 | Jan 7, 2022 | Low confidence |
