This patent's term runs 2 days past its 20-year base term on 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. Confidence: High. 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 |
|---|---|---|---|

| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | +2 days, USPTO patent term adjustment record | Oct 14, 2026 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 8,114,656) | resolves to Oct 14, 2026, 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 |
