Welcome to i-BIS;

International Business and Inventions Services


i-BIS; International Business and Inventions Services has been actively engaged in education and research, especially in the field of intellectual property, with the support of many customers from the beginning of office registration. Our office was registered in April 1994. In the midst of changes such as the strengthening of Japan's intellectual property strategy in 2002, the recent progress of real and full-scale globalization, and the arrival of a new era of IoT, AI, and 5G, and unexpected events such as the recent corona pandemic era, we have been engaged in educational research and dissemination activities related to strategy formulation in the field of intellectual property.
Yoshitoshi Tanaka, the director of our office, retired from Tokyo Institute of Technology at the end of March 2020, and has been devoting himself to work at the Ibis International Patent Office since last year. We would be grateful if we could cooperate in resolving the management issues faced by our customers. In particular, how to reflect intellectual property activities in corporate management and contribute to the sustainable growth of the company, and redefinition of intellectual property activities that should be tackled in the increasingly fierce international competition in the future. We would like to cooperate with you for the further development of everyone.
