Maintenance fees paid
Two maintenance fees can end this term early, the ones due 3.5 and 7.5 years from grant; the third one's grace period runs past the term end. This counts the ones the record shows paid.
This patent's term runs 69 days past its 20-year base term on prosecution delay. A terminal disclaimer resolved from the filed document caps it earlier. 2 of 2 maintenance fees are 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 Nov 22, 2006, when application 11/603,178, the earliest non-provisional in its chain, was filed (this one was filed Aug 27, 2015); a parent in its chain could not be resolved (the next row) | Nov 22, 2026 | 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 | +69 days, USPTO patent term adjustment record | Jan 30, 2027 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 9,125,190) | capped to Nov 22, 2026 | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 2 of 2 maintenance fees paid | In force | High confidence |
| Further caveats on record | The record names parents not resolved: 13217572, 11603178, 13217572, 11603178 | Low confidence overall | Low confidence |
| Computed term end | The steps above, in order | Nov 22, 2026 | Low confidence |
Assignments
Assignment documents as recorded at the USPTO, oldest first, with the reel and frame each was recorded at. A recorded assignment is a filed document, not a statement of current ownership, and the absence of a later one is not evidence that the last one still stands.
