This patent's term is its 20-year base term, with no adjustment for prosecution delay. A terminal disclaimer is resolved from the filed document, and it ends no earlier than this term, so it shortens nothing. 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 Feb 2, 2007, when application 11/701,699, the earliest non-provisional in its chain, was filed (this one was filed Aug 19, 2013); a parent in its chain could not be resolved (the next row) | Feb 2, 2027 | 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 8,524,883) | resolves to Feb 2, 2027, no earlier than this term, so no change | 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; the fee record shows no payment for this window, and USPTO's status still reads "Patented Case" | no change | Low confidence |
| Reissue | US RE47,301 issued Mar 19, 2019, and this patent's term continues in it (35 U.S.C. 251, 252) | surrendered Mar 19, 2019 | High confidence |
| Surrendered on reissue | The steps above, in order | Mar 19, 2019 | Low confidence |
