Term ends no later than Oct 2, 2027 · Low confidence
20-year base term ends Oct 1, 2027
In force on USPTO's status record and by its fee record. A terminal disclaimer on file may shorten this term, possibly to a date already past; its reference document is unresolved, so the date above is an upper bound and no earlier date is guessed.

USPTO first gave this application the number US 8,914,402 and withdrew it before it issued. That number now leads here.

Family applications on record here
Applications sharing this one's continuity chain whose file history this site holds. The family may have others.
This patent's term runs 1 days past its 20-year base term on prosecution delay. A terminal disclaimer is on file with no resolved reference, so no cap is applied and none is guessed. 2 of 3 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 Oct 1, 2007, when applications 11/865,692, 11/865,694 and 11/865,697, the earliest non-provisional applications in its chain, were filed (this one was filed Aug 27, 2010); a parent in its chain could not be resolved (the next row) | Oct 1, 2027 | 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 | +1 days, USPTO patent term adjustment record | Oct 2, 2027 | 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 | 2 of 3 maintenance fees paid | In force | High confidence |
| Computed term end | The steps above, in order | no later than Oct 2, 2027 | Low confidence |

How we rank
Every date shows its work: the base term, any term adjustment or extension, any disclaimer cap, and the maintenance fee record, each with a confidence tier. How this record was built
This computed term ends no later than the date shown; an unresolved terminal disclaimer may end it earlier. Related patents and pending applications may cover overlapping subject matter.
In force means the term is running and no lapse is on record. It is not a finding that the patent is valid.
