How this date was computed
Every step shows its rule, its 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 Apr 8, 2005 | Apr 8, 2025 | High |
| Continuity chain | chain has unresolved parents (dated from child's own claim) | dated from this application's own claim | Medium |
| Patent term adjustment | +206 days, USPTO PTA record | Oct 31, 2025 | High |
| Terminal disclaimer cap | Disclaimer on file (approved), reference document not resolved | no cap applied, and none guessed | Medium |
| Patent term extension | None on file | no change | High |
| Fee events | 2 of 3 maintenance fees paid | lapsed Oct 6, 2021 | High |
| Computed term end | The steps above, in order | Oct 6, 2021 | Low |

What's changing
Note
A terminal disclaimer is on file and its reference is not resolved. No cap is applied and none is guessed
Note
The 206 days of PTA are read from the USPTO record, not recalculated by us
Open question
A terminal disclaimer is on file (approved) and its reference document is not resolved. A disclaimer would cap the term earlier than Oct 6, 2021. We will not guess the cap.
