Furthermore, analysis the time delay of patent licensing. The results show that the most of licensed patents are individual, international licensing is less, the patent licensing has delay, and more than 90% patents are licensed six years later after application. © 2018 Portland International Conference on Management of Engineering and Technology, Inc.
