PartnerTakuya MITANI

Mr. Mitani received his B. Eng. in electrical engineering (1996) and his M. S. in energy science (1998) from Kyoto University. He researched virtual reality technologies consistently through his bachelor’s and master’s courses. He developed simulation systems for maintenance at nuclear plants, and completed a master’s thesis on “Application of Multimodal Communication to Equipment Maintenance System in Distributed Virtual Environment.”

He worked as a software engineer in R & D department of Hewlett - Packard from 1998 to 2002, where he engaged in design and coding (mainly the C++ Language) of remote control modules for embedded systems (multithreading management), communication software, user interfaces, measurement commands, etc.

He worked for patent firms from 2003 to 2015 where he handled patent prosecutions, appeals, etc. in Japan and foreign countries and also provided a large number of expert opinions relating to invalidation and infringement. He also researched mathematical models for evaluation of patent rights.
