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.

|---|---|---|---|
| Base term, 20 years from filing | Clock starts Oct 6, 2004, when the earliest non-provisional application in its chain was filed (this one was filed Jun 13, 2005); a parent in its chain could not be resolved (the next row) | Oct 6, 2024 | 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 | +1920 days, USPTO patent term adjustment record | Jan 8, 2030 | 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 | 2 of 3 maintenance fees paid | lapsed Nov 15, 2023 | High confidence |
| Computed term end | The steps above, in order | Nov 15, 2023 | Medium confidence |
