Its term would have run to Feb 5, 2030: its 20-year base term plus 352 days of term 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. Confidence: Low. 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, 20 years from filing | Clock starts Feb 18, 2009, when application 12/372,809, the earliest non-provisional in its chain, was filed (this one was filed Nov 25, 2011) | Feb 18, 2029 | High confidence |
| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | +352 days, USPTO patent term adjustment record | Feb 5, 2030 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 8,131,692) | resolves to Feb 5, 2030, no earlier than this term, so no change | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | The fee record shows no payment for this window, and USPTO's status still reads "Patented Case" | lapsed Sep 23, 2026 | Medium confidence |
| Further caveats on record | The record rates this date lower than the steps above account for | Low confidence overall | Low confidence |
| Computed term end | The steps above, in order | Sep 23, 2026 | Low confidence |
