| Patent term adjustment | +67 days, USPTO patent term adjustment record | Dec 9, 2026 | High confidence |
| Terminal disclaimer cap | Disclaimer on file (approved), reference document not resolved | no cap applied, and none guessed | Medium confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 1 of 1 maintenance fees paid | In force | High confidence |
| Computed term end | The steps above, in order | no later than Dec 9, 2026 | Low confidence |

What's changing
A terminal disclaimer is on file (approved) and its reference document is not resolved. A disclaimer would cap the term earlier than Dec 9, 2026. We will not guess the cap.
