| Abstract: | The paper describes work on a citation network starting from ten U.S. patents and comprising 1204 journal articles and 43 patents in the field of prostaglandins. A journal citation network was created independently from 85 recent articles on the subject. It was found that the two networks were virtually identical except that the former included patents and was therefore more complete. It was found that the most highly cited references were those widely regarded as being key turning points in the development of the subject.The results demonstrate that in a subject field which incorporates patentable subject-matter matter, a patent/journal citation network is fuller and more reliable than a patent citation network or a journal citation network on their own. |
