20-year base term ends Dec 16, 2030

|---|---|---|---|
| Base term, 20 years from filing | Clock starts Dec 16, 2010, when application 12/970,072, the earliest non-provisional in its chain, was filed (this one was filed Apr 1, 2014) | Dec 16, 2030 | High confidence |
| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | +12 days, USPTO patent term adjustment record | Dec 28, 2030 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 9,052,224) | resolves to Dec 28, 2030, no earlier than this term, so no change | Medium confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 2 of 3 maintenance fees paid | In force | High confidence |
