This patent's term runs 469 days past the statutory base term on prosecution delay. All three maintenance fees are paid, so nothing but the term itself will end it. Confidence: Medium. 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, 20y-from-earliest-nonprovisional | Clock starts Oct 28, 2005 | Oct 28, 2025 | 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 | +469 days, USPTO PTA record | Feb 9, 2027 | 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 | 3 of 3 maintenance fees paid | In force | High confidence |
| Computed term end | The steps above, in order | Feb 9, 2027 | Medium confidence |
