Its term would have run to Dec 1, 2026: its 20-year base term plus 387 days of term adjustment for prosecution delay. A terminal disclaimer is on file with no resolved reference, so no cap is applied and none is guessed. 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 Nov 9, 2005, when application 11/270,866, the earliest non-provisional in its chain, was filed (this one was filed Apr 6, 2015); a parent in its chain could not be resolved (the next row) | Nov 9, 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 | +387 days, USPTO patent term adjustment record | Dec 1, 2026 | High confidence |
| Terminal disclaimer cap | Disclaimer on file (approved), reference document not resolved | no cap applied, and none guessed | Medium confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 1 of 2 maintenance fees paid | lapsed May 15, 2026 | High confidence |
| Computed term end | The steps above, in order | May 15, 2026 | Low confidence |
