Abstract
The history and the process in the development of pharmaceutical products with biotechnology in Genentech Inc. were investigated and a kind of innovation dynamics was found in it. Genentech developed a process technology for recombinant proteins around 1980. Genentech accomplished their successive product development with this recombinant technology. Moreover, the recombinant technology induced an unique process technology for antibody products around 1990. Genentech accomplished their next successive antibody product development with the antibody technology. A recombinant technology induced not only a dynamics to recombinant products but also to an antibody process technology. Such an unique and successive innovation was a reason why Genentech accomplished a series of recombinant products and recombinant antidoby products. These dynamics in Genentch seems different from that found in typewriter industry field reported by Utterback (1998).
