While the parent comment is completely wrong that it was acquired from them when it is actually an Apple patent Fingerworks is mentioned in the "Other references" (that is references to things that aren't patents) section:
PR Newswire, "FingerWorks Announces a Gestrue Keyboard for Apple PowerBooks," Jan. 27, 2004, 2 pages. cited by other .
PR Newswire, "FingerWorks Announces the ZeroForce iGesture Pad," Feb. 18, 2003, 2 pages. cited by other .
I haven't studied the cited patents, some of them may also refer to Fingerworks.
