KFx Medical has sued Stryker for its continued infringement of US Patent number 7,585,311 and associated patents for knotless double row rotator cuff repair.
In 2015, when KFx successfully defended these patents versus Arthrex, Inc., Arthrex paid in excess of $35m in damages and interest for its infringement of these same KFx Knotless Double Row Fixation patents and fought KFx through the appellate court and was ultimately denied any further review by the Supreme Court of the United States.
KFx Medical, has 5 agreements that license the same patents to other medical device companies, giving them the right to promote the use of products and techniques for knotless double row rotator cuff repair as claimed in US Patent number 7,585,311 and related patents and applications for the life of those patents.
KFx Medical LLC was founded in 2003 to develop products for tissue fixation in a variety of orthopedic surgical procedures performed on the shoulder, knee, foot, and ankle.
KFx provides simple systems for orthopedic surgeons focused on sports medicine. The company is privately held. Investors include Alloy Ventures, Charter Life Sciences, Arboretum Ventures, Montreux Equity Partners, and MB Venture Partners.
