Hopkins' Stem Cell Selection Patents Upheld

Hopkins' Stem Cell Selection Patents Upheld

WILMINGTON, Del--A Federal judge has ordered CellPro, Inc. to pay Johns Hopkins University, Becton Dickinson & Company, and Baxter Healthcare Corp. $7 million in damages for its willful infringement of patents involving stem cell selection technology.

The judge also ordered an injunction against CellPro's patent-infringing stem cell selection system (Ceprate Stem Cell Concentration System and Ceprate LC34 Laboratory Cell Separation System). This injunction will be delayed in this country until an alternative system, licensed under the patents, is approved by the FDA.

Johns Hopkins and its licensees requested the delay to ensure that transplant patients have uninterrupted access to stem cell selection technology. Baxter's Isolex 300 Magnetic Cell Separator System, already in widespread use in clinical trials, is currently under FDA review.
