|---|---|---|---|
| Base term, 20 years from filing | Clock starts Dec 5, 2006, when application 11/633,780, the earliest non-provisional in its chain, was filed (this one was filed Jan 22, 2014); a parent in its chain could not be resolved (the next row) | Dec 5, 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 | None on file | no change | 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 | 3 of 3 maintenance fees paid | In force | High confidence |

Every date shows its work: the base term, any term adjustment or extension, any disclaimer cap, and the maintenance fee record, each with a confidence tier. How this record was built
