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.

| 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 |
