THE STRUCTURE OF BIOTECHNOLOGY RESEARCH-AND-DEVELOPMENT

The structure of R & D in biotechnology is analysed using co-classific ation analysis of joint subject heading assignments in Derwent BIOTECH NOLOGY ABSTRACTS and subject profile analysis of 44 highly productive biotechnology-intensive organizations whose patents and publications a re indexed therein. A Pathfinder Network Analysis reveals two distinct foci in biotechnology R & D - fermentation and genetic engineering - each linked to relevant products and secondary processes. Multidimensi onal scaling and cluster analysis identified 5 major groupings of comp anies, research institutes, and patent-holding organizations arranged along two dimensions - industrial fermentation processes vs genetic en gineering and biomedical vs non-biomedical R & D.
