|---|---|---|---|
| Base term, 20 years from filing | Clock starts Mar 27, 2009 | Mar 27, 2029 | High confidence |
| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | +446 days, USPTO PTA record | Jun 16, 2030 | High confidence |
| Terminal disclaimer cap | None on record | no cap applied | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 3 of 3 maintenance fees paid | In force | High confidence |
| Computed term end | The steps above, in order | Jun 16, 2030 | High confidence |
