How we calculated this date
| Step | Input | Date after this step | Confidence |
|---|---|---|---|
| Base term, 20 years from filing | Clock starts May 21, 2004, when the earliest non-provisional application in its chain was filed (this one was filed Jul 10, 2012); a parent in its chain could not be resolved (the next row) | May 21, 2024 | 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 | +55 days, the original patent's USPTO patent term adjustment record, which governs a reissue (35 U.S.C. 251). This reissue's own record carries none | Jul 15, 2024 | Medium confidence |
| Terminal disclaimer cap | Disclaimer on file (approved), reference document not resolved | no cap applied, and none guessed | Medium 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 | term ended | Medium confidence |
| Computed term end | The steps above, in order | no later than Jul 15, 2024 | Low confidence |

USPTO account required: This application in Patent Center · USPTO's maintenance fee lookup
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
This computed term ends no later than the date shown; an unresolved terminal disclaimer may end it earlier. Related patents and pending applications may cover overlapping subject matter.
