How we calculated this date
| Step | Input | Date after this step | Confidence |
|---|---|---|---|
| Base term, 20 years from filing | Clock starts Dec 22, 2000, when the earliest non-provisional application in its chain was filed (this one was filed Mar 10, 2014); a parent in its chain could not be resolved (the next row) | Dec 22, 2020 | 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 7,647,070, US 8,019,384, US 8,175,642, US 8,706,161) | resolves to Dec 22, 2020, no earlier than this term, so no change | Medium confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 1 of 1 maintenance fees paid | term ended | High confidence |
| USPTO status record | Recorded as expired for non-payment on Jul 17, 2023, after the term ended | no change | High confidence |
| Computed term end | The steps above, in order | Dec 22, 2020 | Medium confidence |
