Abstract
Technology transfer from university to private company is one of the major outcomes of TLOs and academia-industry collaboration sections in university. This paper describes, through the experience worked in Nihon University, that the contribution of researchers (inventors) is very important to promote licensing activities in university. It shows that the information from researchers about companies of potential future licensees is very useful to close on license agreements. It is also shown that patents solved the inventors' own research problems are often easier to be licensed than the other patents, with the inventors' earnest cooperation for licensing. Furthermore, this type of licensing with such patents is one of the clear outcomes of technology transfer activities in university and it directly supports the researcher's daily activities.
