How we calculated this date
| Step | Input | Date after this step | Confidence |
|---|---|---|---|
| Base term, 20 years from filing | Clock starts Nov 14, 2005, when the earliest non-provisional application in its chain was filed (this one was filed Sep 6, 2011); a parent in its chain could not be resolved (the next row) | Nov 14, 2025 | 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 | +1135 days, USPTO patent term adjustment record | Dec 23, 2028 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 8,024,653) | capped to Mar 1, 2028 | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 2 of 3 maintenance fees paid | In force | High confidence |
| Further caveats on record | The record names parents not resolved: 11273568, 11314835, 11273568, 11314835 | Low confidence overall | Low confidence |
| Computed term end | The steps above, in order | Mar 1, 2028 | 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
Computed patent terms end on the dates shown. Related patents and pending applications may cover overlapping subject matter.
In force means the term is running and no lapse is on record. It is not a finding that the patent is valid.
