|---|---|---|---|
| Base term, 20 years from filing | Clock starts Feb 2, 2007, when application 11/701,699, the earliest non-provisional in its chain, was filed (this one was filed Dec 21, 2011) | Feb 2, 2027 | High confidence |
| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | None on file | no change | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 7,671,192, US 7,732,595, US 8,106,183, US 8,268,988) | resolves to Feb 2, 2027, no earlier than this term, so no change | Medium confidence |
| Patent term extension | None on file | no change | High confidence |
