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 19, 2007, when application 11/875,500, the earliest non-provisional in its chain, was filed (this one was filed Apr 30, 2013); a parent in its chain could not be resolved (the next row) | Oct 19, 2027 | 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 | +133 days, USPTO patent term adjustment record | Feb 29, 2028 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 8,225,398) | capped to Oct 19, 2027 | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 2 of 3 maintenance fees paid | In force | High confidence |
