This patent's term is its 20-year base term, with no adjustment for 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 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 2, 2008, when application 12/244,723, the earliest non-provisional in its chain, was filed (this one was filed May 13, 2013); a parent in its chain could not be resolved (the next row) | Oct 2, 2028 | 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 | None on file | no change | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 8,822,167) | resolves to Oct 2, 2028, no earlier than this term, so no change | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 2 of 3 maintenance fees paid | In force | High confidence |
| Further caveats on record | The record names parents not resolved: 13889674, 13326023, 12244723 | Low confidence overall | Low confidence |
| Computed term end | The steps above, in order | Oct 2, 2028 | Low confidence |
