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 8, 2006, when applications 11/430,511, 11/431,093, 11/431,118 and 11/431,140, the earliest non-provisional applications in its chain, were filed (this one was filed Jun 26, 2008); a parent in its chain could not be resolved (the next row) | May 8, 2026 | 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 | +1290 days, USPTO patent term adjustment record | Nov 18, 2029 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 8,409,103) | capped to Apr 12, 2029 | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 3 of 3 maintenance fees paid | In force | High confidence |
