Citation and referencing data from recent biotechnology patents and bioscience papers is used to show that the bibliometric properties in these two realms are quite similar. Specifically, it is shown that the time distribution of references from both patents and papers are similar, with peak citing at two to four years prior to publication or issue. This is shown to hold for patents citing patents, for papers citing papers, and for patents citing papers. Furthermore, it is shown that there is a very skewed distribution of cited material in both patents and papers, with a relatively small number of highly cited patents and papers, and a relatively large number of documents which are cited only once or twice, or not at all. Finally, it is shown that there is a substantial amount of citation from biotechnology patents to the central scientific literature. We conclude from this that science and technology are far more closely linked today than is normally perceived, and that, in fact, the division between leading edge biotechnology and modern bioscience has alsmot completely disappeared.
