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 May 9, 2006, when application 11/431,942, the earliest non-provisional in its chain, was filed (this one was filed Nov 15, 2006) | May 9, 2026 | High confidence |
| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | +77 days, USPTO patent term adjustment record | Jul 25, 2026 | High confidence |
| Terminal disclaimer cap | Disclaimer on file (approved), reference document not resolved | no cap applied, and none guessed | Medium confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 1 of 2 maintenance fees paid | lapsed Dec 23, 2022 | High confidence |
| Computed term end | The steps above, in order | Dec 23, 2022 | Medium confidence |
