Why Medium: The disclaimer's references carry disclaimers of their own not yet read (US 8,188,985), so the cap could be lower.
USPTO later recorded it as expired for non-payment on Apr 13, 2026.

How we calculated this date
| Step | Input | Date after this step | Confidence |
|---|---|---|---|
| Base term, 20 years from filing | Clock starts Aug 6, 2004, when the earliest non-provisional application in its chain was filed (this one was filed Apr 27, 2012) | Aug 6, 2024 | High confidence |
| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | None on file | no change | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 8,188,985) | resolves to Aug 6, 2024, no earlier than this term, so no change | Medium 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 Apr 13, 2026, after the term ended | no change | High confidence |
| Computed term end | The steps above, in order | Aug 6, 2024 | Medium confidence |
