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 Apr 1, 2002, when application 10/114,798, the earliest non-provisional in its chain, was filed (this one was filed Sep 10, 2012) | Apr 1, 2022 | High confidence |
| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | +1010 days, USPTO patent term adjustment record | Jan 5, 2025 | High 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; the fee record shows no payment for this window, and USPTO's status still reads "Patented Case" | no change | Low confidence |
| Reissue | US RE48,845 issued Dec 7, 2021, and this patent's term continues in it (35 U.S.C. 251, 252) | surrendered Dec 7, 2021 | High confidence |
| Surrendered on reissue | The steps above, in order | Dec 7, 2021 | Low confidence |
