|---|---|---|---|
| Base term, 20 years from filing | Clock starts Mar 31, 2003, when this application, 10/404,573, was filed | Mar 31, 2023 | High confidence |
| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | +1376 days, USPTO patent term adjustment record | Jan 5, 2027 | 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 |
