|---|---|---|---|
| Base term, 20 years from filing | Clock starts Apr 17, 2012, when this application, 13/449,153, was filed | Apr 17, 2032 | High confidence |
| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | +158 days, USPTO patent term adjustment record | Sep 22, 2032 | 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 (reinstated) | High confidence |
| Computed term end | The steps above, in order | Sep 22, 2032 | 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
