Abstract “Patent licensing” refers to the role and status of licensors and licensees in the technology market. “Patent citation” reflects the existing and potential relationships between citing and cited patents in the technical knowledge field. Thus, patent licensing and patent citation have a natural and deep-seated logical connection. Patent citation occurs before when patent rights are issued, while patent licensing may or may not occur after when patent rights are issued. It is therefore possible to predict patent licensing by analyzing the characteristic index related to patent citation. This study examines the communication industry, in which patent licensing is a common practice. We measured 4,985 licensing patents by 540 licensors and their 1,332 forward citations together with 6,876 backward citations. Next, we analyzed the correlations between the variables related to patent citation and the probability of patent licensing. We then attributed the correlations of these variables to the principles of innovation economics and constructed the patent license prediction index using the Brovey converter model, which was proved to be effective through experiments.
