He is fluent in Japanese and worked for more than four years in Japan, both as an attorney at a Japanese law firm and for a Japanese company. He has written about patent monetization and Internet privacy issues and has spoken, in Japanese and English, on topics such as trends in e-discovery and patent exhaustion.
