This patent's term runs 30 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. 1 of 2 maintenance fees is paid so far. 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 Sep 14, 2011, when application 13/232,310, the earliest non-provisional in its chain, was filed (this one was filed Dec 1, 2017); a parent in its chain could not be resolved (the next row) | Sep 14, 2031 | 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 | +30 days, USPTO patent term adjustment record | Oct 14, 2031 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 9,155,964, US 9,861,893) | resolves to Oct 14, 2031, no earlier than this term, so no change | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 1 of 2 maintenance fees paid | In force | High confidence |
| Further caveats on record | The record names parents not resolved: 14852002, 13232310 | Low confidence overall | Low confidence |
| Computed term end | The steps above, in order | Oct 14, 2031 | Low confidence |
