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 May 18, 2010, when application 12/782,569, the earliest non-provisional in its chain, was filed (this one was filed Apr 22, 2015) | May 18, 2030 | High confidence |
| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | +662 days, USPTO patent term adjustment record | Mar 10, 2032 | 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" | lapsed Oct 23, 2026 | Low confidence |
| Computed term end | The steps above, in order | Oct 23, 2026 | Low confidence |
