Three Indian biotech firms, including two from the city, planned to set up research and development centres at the Frankfurt Innovation Centre for Biotechnology (FIZ), a top FIZ official said on Monday. “We are in final stages of discussions with three Indian firms to set up base at FIZ. Two are from Bangalore and the other from Pune,” FIZ managing director and CEO Christian Garbe told reporters. He declined to name the firms, but said an agreement was likely to be signed in October during the visit of Prime (Chief) Minister of German state of Hesse, Roland Koch.
