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 1, 2008, when this application, 12/243,852, was filed | Oct 1, 2028 | High confidence |
| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | +630 days, USPTO patent term adjustment record | Jun 23, 2030 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 8,051,159) | capped to Aug 7, 2029 | Medium confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 3 of 3 maintenance fees paid | In force | High confidence |
| Computed term end | The steps above, in order | Aug 7, 2029 | Medium confidence |
