SAN DIEGO–(BUSINESS WIRE)–KFx Medical, LLC. announced it has sued Stryker, Inc. (NYSE: SYK) for its continued infringement of US Patent number 7,585,311 and related 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, LLC 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.
