|---|---|---|---|
| Base term, 20 years from filing | Clock starts Jun 25, 1999, when the earliest non-provisional application in its chain was filed (this one was filed Jun 2, 2006); a parent in its chain could not be resolved (the next row) | Jun 25, 2019 | 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 | +1091 days, USPTO patent term adjustment record | Jun 20, 2022 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 6,850,965) | capped to Feb 17, 2021 | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 2 of 2 maintenance fees paid | term ended | High confidence |
| USPTO status record | Recorded as expired for non-payment on Dec 5, 2022, after the term ended | no change | High confidence |
| Further caveats on record | The record names parents not resolved: 09344688 | Low confidence overall | Low confidence |
| Computed term end | The steps above, in order | Feb 17, 2021 | Low confidence |
