On June 10, 2013, AngleFix Tech, LLC sued Wright Medical Technology, Inc. in the Western District of Tennessee. AngleFix’s complaint alleges that Wright Medical’s plate and screw systems for bone fixation infringe U.S. Patent No. 6,955,677 entitled “Multi-Angular Fastening Apparatus and Method for Surgical Bone Screw/Plate Systems.” The accused systems include the Claw, Claw II, Charlotte Claw, Ortholoc, Ortholoc 3Di, and Ortholoc 3Di2.
The complaint states that the ‘677 Patent was the result of the inventor’s “desire to capture bone fragments during orthopedic surgery that would otherwise evade locking screws set at a single fixed angle.” The Abstract of the ‘677 Patent describes an apparatus including a fastener and a fastener receiving member that “enables the fastener to be affixed to the fastener receiving member at a variable insertion angle selected by the user.” Figure 3 from the ‘677 Patent is shown below:
AngleFix is based in North Carolina and holds an exclusive license to the ‘677 Patent from the University of North Carolina. AngleFix sued NuVasive, Inc. on the same patent in the Southern District of California earlier this year.
