|---|---|---|---|
| Base term, 20 years from filing | Clock starts Aug 30, 2010, when this application, 12/871,402, was filed | Aug 30, 2030 | 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 | 3 of 3 maintenance fees paid | In force | High confidence |

Assignment documents as recorded at the USPTO, oldest first, with the reel and frame each was recorded at. A recorded assignment is a filed document, not a statement of current ownership, and the absence of a later one is not evidence that the last one still stands.
