|---|---|---|---|
| Base term, 20 years from filing | Clock starts Feb 8, 2002, when application 10/072,683, the earliest non-provisional in its chain, was filed (this one was filed Dec 30, 2013); a parent in its chain could not be resolved (the next row) | Feb 8, 2022 | 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 8,370,936) | resolves to Feb 8, 2022, no earlier than this term, so no change | High 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 Sep 4, 2023, after the term ended | no change | High confidence |
