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 Mar 4, 2009, when this application, 12/398,111, was filed | Mar 4, 2029 | High confidence |
| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | +230 days, USPTO patent term adjustment record | Oct 20, 2029 | 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"; the grace period ended with no payment on record in the fee file | grace period ended Oct 28, 2026 | Low confidence |
| Computed term end | The steps above, in order | Oct 20, 2029 | Low confidence |
