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 77 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. 2 of 2 maintenance fees are paid so far. 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 |
|---|---|---|---|
| Base term, 20 years from filing | Clock starts Aug 31, 2006, when application 11/513,312, the earliest non-provisional in its chain, was filed (this one was filed Feb 11, 2014) | Aug 31, 2026 | High confidence |
| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | +77 days, USPTO patent term adjustment record | Nov 16, 2026 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 8,649,792) | resolves to Nov 16, 2026, no earlier than this term, so no change | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 2 of 2 maintenance fees paid | In force | High confidence |
| Computed term end | The steps above, in order | Nov 16, 2026 | High 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.
