How we calculated this date
| Step | Input | Date after this step | Confidence |
|---|---|---|---|
| Base term, 20 years from filing | Clock starts Feb 12, 2008, when the earliest non-provisional application in its chain was filed (this one was filed Nov 29, 2012); a parent in its chain could not be resolved (the next row) | Feb 12, 2028 | 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 | Disclaimer resolved from the filed document (refs US 8,380,368) | resolves to Feb 12, 2028, no earlier than this term, so no change | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 1 of 3 maintenance fees paid | lapsed Feb 11, 2022 | High confidence |
| Further caveats on record | The record names parents not resolved: 13471642, 12029470 | Low confidence overall | Low confidence |
| Computed term end | The steps above, in order | Feb 11, 2022 | Low confidence |

Maintenance fee events come from USPTO's own fee records. Its fee lookup asks for the patent number and the application number.
Not on this page: the patent's family, its recorded assignments and its citation count. USPTO's assignment records, linked above, list every recorded assignment.
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
