Assignments
The 40 most recent of 62 recorded documents are shown; the 22 earliest are not. 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.
