| Continuity chain | chain has unresolved parents (dated from child's own claim) | dated from this application's own claim | Medium confidence |
| Patent term adjustment | +601 days, USPTO PTA record | Feb 6, 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 | 1 of 3 maintenance fees paid | lapsed Jun 28, 2024 | High confidence |
| Computed term end | The steps above, in order | Jun 28, 2024 | Medium confidence |
