* Baxter International Inc., of Deerfield, Ill., and two associates have asked a federal court in Delaware to issue a permanent injunction against sales of Bothell, Wash.-based CellPro Inc.'s Ceprate SC Stem Cell Concentration System, which was approved by the FDA in December 1996. The move followed a court ruling that CellPro's product infringed patents held by Baxter, Becton Dickinson & Co., of Franklin Lakes, N.J., and Johns Hopkins University, of Baltimore. CellPro also has been ordered to pay damages. Although Baxter is seeking a permanent injunction, the company said CellPro should continue selling its product until the FDA approves Baxter's competing device, Isolex 300 Magnetic Cell Separator System. CellPro has said it is appealing the court's patent infringement decision.
