This paper examines tripartite relationship between industry, patent firm and patent attorney. The purpose of this research is to analyze how transaction structure between companies and patent firms affects career switch of patent attorneys. We collect data of transaction between top 50 research oriented companies and top 50 patent firms in Japan and also data of the profiles of 1,960 patent attorneys who belong to the patent firms. Our final dataset covers about 50% of all published patents in 2013. Based on quantitative analysis, we observe three major findings as follows. Firstly, the transactions between companies and patent firms are fixed and long-term. 70.9% of these transaction relationships have not changed for five years. Secondly, 29.6% of the patent attorneys have switched their career in five years. However, only 18.4 % of them have gone into private practice. That means only 4.7% of all patent attorneys have set up their own patent firm. Thirdly, these patent attorneys lost their clients after they have been independent from the top 50 patent firms. In sum, it is relatively difficult for patent attorneys to start new transactions with top 50 companies and to establish their own patent firm. That may suppress their willingness to be independent.
