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 Jun 27, 2011, when application 13/170,181, the earliest non-provisional in its chain, was filed (this one was filed Sep 21, 2011) | Jun 27, 2031 | High confidence |
| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | +535 days, USPTO patent term adjustment record | Dec 13, 2032 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 8,963,810, US 8,963,811) | resolves to Dec 13, 2032, no earlier than this term, so no change | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 3 of 3 maintenance fees paid | In force | High confidence |
