How we calculated this date
| Step | Input | Date after this step | Confidence |
|---|---|---|---|
| Base term, 20 years from filing | Clock starts Nov 28, 2006, when the earliest non-provisional application in its chain was filed (this one was filed Apr 1, 2015); a parent in its chain could not be resolved (the next row) | Nov 28, 2026 | High confidence |
| Continuity chain | A reissue: its term follows the original patent's, with the original's term adjustment; a parent in the chain could not be resolved | dated from this application's own claim | Low confidence |
| Patent term adjustment | No term adjustment record on a grant after 2005, so none is added | no change | Medium confidence |
| Terminal disclaimer cap | None on record | no cap applied | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | No fee event states this; the fee state is read from the payments the fee record holds | In force | Medium confidence |
| Computed term end | The steps above, in order | Nov 28, 2026 | From the USPTO record |

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.
