| Step | Input | Date after this step | Confidence |
|---|---|---|---|
| Base term, 20 years from filing | Clock starts Oct 25, 2007, when the earliest non-provisional application in its chain was filed (this one was filed Aug 9, 2013); a parent in its chain could not be resolved (the next row) | Oct 25, 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 | None on file | no change | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 8,532,713) | capped to Jun 25, 2027 | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 2 of 3 maintenance fees paid | lapsed Dec 24, 2025 | High confidence |
| Further caveats on record | The record names parents not resolved: 13402880, 13093733, 11977763 | Low confidence overall | Low confidence |
| Computed term end | The steps above, in order | Dec 24, 2025 | Low confidence |
