This patent's term is its 20-year base term, with no adjustment for prosecution delay. A terminal disclaimer is resolved from the filed document, and it ends no earlier than this term, so it shortens nothing. All three maintenance fees were paid, so no fee lapse ended it.

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 Sep 7, 2005, when application 11/221,015, the earliest non-provisional in its chain, was filed (this one was filed Jul 16, 2012); a parent in its chain could not be resolved (the next row) | Sep 7, 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 | None on file | no change | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 7,625,453) | resolves to Sep 7, 2025, no earlier than this term, so no change | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 3 of 3 maintenance fees paid | term ended | High confidence |
| Computed term end | The steps above, in order | Sep 7, 2025 | Medium confidence |
