| Continuity chain | A parent in the chain could not be resolved | dated from this application's own claim | Medium confidence |
| Patent term adjustment | +1314 days, USPTO patent term adjustment record | Oct 8, 2023 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 7,975,690) | resolves to Oct 8, 2023, no earlier than this term, so no change | 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 Jan 13, 2025, after the term ended | no change | High confidence |
