This patent's term is its 20-year base term, with no adjustment for prosecution delay. A terminal disclaimer is on file with no resolved reference, so no cap is applied and none is guessed. Confidence: Low. from the record
How we calculated this date
One row per rule, each showing its own input and what it did to the date. A step we could not verify says so instead of resolving itself.
| Step | Input | Date after this step | Confidence |
|---|---|---|---|
| Base term, 20 years from filing | Clock starts Jun 26, 2009, when application 12/492,890, the earliest non-provisional in its chain, was filed (this one was filed Jul 27, 2015) | Jun 26, 2029 | High confidence |
| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | None on file | no change | High 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; the fee record shows no payment for this window, and USPTO's status still reads "Patented Case" | no change | Low confidence |
| Reissue | US RE48,680 issued Aug 10, 2021, and this patent's term continues in it (35 U.S.C. 251, 252) | surrendered Aug 10, 2021 | High confidence |
| Surrendered on reissue | The steps above, in order | Aug 10, 2021 | Low confidence |
