|---|---|---|---|
| Base term, 20 years from filing | Clock starts Jul 27, 2004, when application 10/900,803, the earliest non-provisional in its chain, was filed (this one was filed Aug 11, 2011); a parent in its chain could not be resolved (the next row) | Jul 27, 2024 | 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 8,021,604) | resolves to Jul 27, 2024, no earlier than this term, so no change | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 1 of 3 maintenance fees paid | lapsed Jun 26, 2020 | High confidence |
| Computed term end | The steps above, in order | Jun 26, 2020 | Medium confidence |
