Arthrex Inc., of Naples, Fla., is well known for lobbing a legal hand grenade into the inter partes review (IPR) process for patent disputes, but the company is now drawing ink for a different legal reason. According to the U.S. Department of Justice (DoJ), Arthrex has agreed to pay $16 million to settle allegations that it engaged in kickbacks to a surgeon, payments ostensibly made to pay for assistance with device design, but which the DoJ claims were intended to induce the surgeon’s use and endorsement of Arthrex products.
